Foto di bawah adalah fasilitas produksi Berto Roaster di kota Tangerang, Jawa Barat. Di tempat inilah kami membuat mesin roaster kopi kami sejak tahun 2017. Tim kami terdiri dari insinyur yang terampil dan teknisi yang berpengalaman, ahli otomatisasi profesional, dan pakar kopi yang bekerja sama untuk membuat mesin roaster terbaik bagi bisnis Anda.

Perjalanan kami tidak dimulai dengan kopi

Berto didirikan pada tahun 1994 oleh Robert Patilaya sebagai fasilitas produksi mesin kosmetik. Beberapa tahun kemudian, selama dekade 90-an kami mulai fokus pada pembuatan mesin pengolah makanan. Kami adalah perusahaan pertama di Indonesia yang memproduksi mesin-mesin khusus seperti enrober, cooling tunnel, extruder dan fryer. Selama bertahun-tahun kami bekerja keras membuat mesin kami dan mengekspor produk kami ke berbagai negara di Asia Tenggara, Timur Tengah, Australia dan Eropa.

Kemudian kami mulai mengenal dan jatuh cinta kepada kopi. Pada tahun 2007 kami membuat mesin roasting kopi pertama kami, roaster konveksi dengan kapasitas 60 kilogram. Satu dekade berlalu sebelum kami memberanikan diri dan memutuskan untuk menggabungkan keterampilan teknis kami, pengalaman kami dalam membuat mesin, dan hasrat kuat kami terhadap kopi menjadi satu. Kami membuat komitmen untuk memindahkan seluruh bisnis kami ke dalam industri roasting biji kopi.

Setiap mesin Berto membutuhkan waktu 6 hingga 8 minggu untuk diproduksi, dari bahan baku menjadi sebuah produk akhir. Semua mesin roaster komersial kami terbuat dari bahan stainless steel yang higienis dan aman untuk bahan makanan, tahan lama, dan juga berpenampilan yang menarik. Semua mesin telah melalui standar proses manufaktur kami yang amat tinggi, kontrol kualitas yang ketat dan pengujian sebelum dikirim kepada pelanggan kami. Mesin roaster Berto hampir tidak memerlukan perawatan selain pelumasan biasa untuk sambungan. Kami juga menawarkan garansi selama dua tahun untuk semua produk Berto. Tapi ini bukan alasan utama mengapa Anda membeli produk kami.

Alasan Anda harus menggunakan produk Berto adalah fakta bahwa ketika Anda membeli mesin roaster kopi Berto, Anda mendapatkan lebih dari sekadar mesin roasting biji kopi.

Ketika bisnis sedang amat berkembang, Anda mulai berpikir untuk meningkatkan kapasitas roasting kopi Anda. Selain itu, Anda juga mulai merasa perlu mendelegasikan tugas roasting kopi kepada para operator, namun amatlah penting untuk menjaga kualitas tetap konsisten setiap kali proses roasting kopi dilakukan. Apakah solusinya? Pada artikel ini, kami menyoroti salah satu produk terbaik kami, Berto D-Roasters. Jenis drum roaster kami yang pintar ini mungkin dapat menjadi solusi yang sempurna untuk kebutuhan Anda.

Apa Itu Drum Roaster?

Drum roaster adalah suatu metode untuk mengubah biji kopi hijau menjadi biji kopi sangrai dengan menggunakan sebuah silinder, atau disebut juga sebagai drum, yang dipasang secara horisontal agar setiap biji kopi dapat berputar dengan mudah dan mencapai proses pemanggangan yang merata. Biasanya, silinder ini dipanaskan dari bawah, sehingga biji kopi dipanggang dengan amat perlahan selagi mereka berputar dan berjatuhan di dalam ruangan drum tanpa pernah melakukan kontak dengan api. Di dalam drum roaster, biji kopi dipanaskan secara langsung dengan menggunakan panas dari dinding drum dan juga secara tidak langsung dari udara panas yang terperangkap di dalam drum. Ini adalah kebalikan dari metode kontak api secara langsung di mana panas ditempatkan di dalam ruangan drum, bersentuhan langsung dengan biji kopi dan seketika memanggangnya.

Seorang roaster kopi yang ingin mendapatkan kualitas unggul biasanya memilih untuk bekerja menggunakan drum roaster yang menawarkan keragaman dari segi kecepatan drum dan juga aliran udara. Dengan kecepatan drum yang dapat diubah-ubah, kita dapat mengatur seberapa jauh pergerakan biji kopi di dalam drum, dimana hal ini akan mempengaruhi seberapa banyak biji kopi tersebut terpapar udara panas yang lewat pada satu satuan waktu. Sebuah sendok dipasang di pelat depan mesin roasting, untuk mengambil sampel apabila diperlukan selama proses roasting. Dengan cara ini, operator mesin dapat melakukan pengecekan visual secara teratur selagi proses roasting tengah berlangsung. Setelah proses roasting ini selesai, biji kopi akan jatuh melalui pintu yang terbuka ke dalam wadah pendingin. Di dalam wadah ini, biji kopi didinginkan dengan penyedotan udara panas dan pengadukan konstan. Setelah masa pendinginan dan de-gassing selesai, biji kopi sangrai akhirnya siap untuk dikemas.

Selecting A Commercial Coffee Roaster Machine

If you are looking to buy or upgrade your commercial coffee roaster machine into a large-scale roaster, there are basic things like durability, size, cleanability, and price that you need to consider. The decision will depend on how much green coffee beans you plan to produce each day, your projected capacity over time, your existing and potential markets, your long-term business plan and goals, and how much you can invest in the coffee roasting machine.

In addition, there are some other considerations beyond the roasting machine itself, such as:

• Floor space
• Gas supply
• Ventilation

The ones that are still open find ways to adapt to their new circumstances. Reduced operating hours, a simpler menu, mandatory masks for both workers and customers, hand sanitizer and hand-washing facilities in place, and a cashless payment system all help in reducing the risk of the virus spreading. But how to maintain, if not increase, the coffee sales during the pandemic? In this article, we will share some strategies for coffee businesses to thrive during this difficult time.

How Coffee Businesses Can Survive During the Pandemic

While many businesses are experiencing revenue loss and a substantial slowdown due to COVID-19, it has also inspired business owners to get creative to stay afloat. Some coffee roasters and coffee shops have reacted to what has been an immediate and shocking blow to the business by responding to the demand increase in the direct-to-consumer home segment.

Below are some tips we can share on how to survive and thrive during this pandemic:

1. Strengthen your Standard Operating Procedures

Health protocols are of the utmost importance in today’s business. Take your time to do thorough planning for new business standards and training the employees. From inventory management, cleaning protocols to service protocols, everything has to adhere to the new standards for cleanliness and sanitation for the safety of workers as well as customers.

2. Offer delivery services

As customers stay at home as much as possible, businesses should try to bring their products to the customers’ homes. A lot of coffee roasters and cafes offer free curb delivery or home delivery, and also partner with online delivery services. You can even collaborate with the online delivery services to have regular promotions to attract more customers to purchase your products.

3. Get creative with your products

Going with a simpler menu doesn’t mean that your customers are stuck with very little options. Start selling cold brews or other beverage varieties in 1-Litre bottles for takeaway or online orders that your customers can drink over a two or three days period. Sell specialized coffee beans or coffee beans in seasonal themes with attractive packaging. Collaborate with your local food provider to offer a bundling package of coffee and a special food menu or snack items.

4. Focus on online sales

With reduced hours and fewer visitors, it is time to increase your online presence. Take the extra time to maintain good social media content, organise online coffee-related workshops and meet-ups. Also, shift your focus from in-store sales to selling coffee online by offering discount vouchers for online purchases, coffee subscription plans, or bundling coffee beans with a home brewing kit. 

5. Support the community

Tie-in your promotion with charity to support those affected by the pandemic. You can sell gift cards with a pledge to donate a certain percentage to baristas, coffee farmers, hospitality workers or healthcare workers. Customers will feel they are getting a good bargain and do their part for a noble cause as well.

No matter how disheartening the situation looks at the moment, the economy will eventually turn around. Your business may look entirely different a year from now. Just remember to always plan for growth, to ensure that you are still in business when the good times are back.

What Is A Drum Roaster?

A drum roaster is a method of turning green coffee beans into roasted beans using a cylinder, also called a drum, that is mounted horizontally so that the beans can rotate easily and attain an even roasting process. Usually, the cylinder is heated from underneath, so the beans are roasted slowly as they tumble over inside the chamber without ever contacting the flame. Inside the drum roaster, the beans are roasted directly with the heat from the walls of the drum and also indirectly from the hot air that is trapped inside the drum. This is the opposite of the direct-flame method where the heat is placed inside the chamber, coming into straight contact with the coffee beans and roasting them almost immediately.

A coffee roaster who wishes to obtain a superior quality usually works with drum roasters that offer a versatility to play around with drum speed and airflow. With a variable drum speed, one can determine the agitation of the beans inside the drum, which affects how much of the beans are exposed to the passing hot air at any one time. A spoon is attached at the front plate of the roasting machine,  to take samples whenever necessary during the roasting process. This way, the operator can do regular visual checks of his roast. After the roasting process is finished, the beans fall through an opening door into a cooling bin. In this bin, the beans are cooled down by air suction and constant stirring. After the cooling down and de-gassing period is concluded, the roasted coffee beans are finally ready to be packed.

1. Guaranteed quality of the raw coffee beans, proven by 40 years of experience as a coffee processor
2. Guaranteed quality of the roasted coffee beans, as their roaster machine is connected to the computer to ensure the roast consistency
3. The value for money

Dapoer Kopi is quite optimistic with the future of the coffee industry in Indonesia. With the population of over 250 million people, clearly this country is a huge market and a lot of things can be improved. Their coffee philosophy is very simple: Coffee For Everyone.

Experience and Passion Is The Key To Be A Successful Coffee Roastery

As mentioned before, Dapoer Kopi’s family background in North Toraja is a coffee processor with roughly 40 years of work experience in the coffee industry. In 2008, a client in Jakarta asked “Why don’t you start selling Toraja coffee?” With the intention of being the best Toraja coffee roastery in Indonesia, they started to introduce Toraja Sapan as native coffee beans of North Toraja. The business started with an initial inventory of only 5kg of roasted coffee beans, which took around six months to sell in Jakarta. Slowly the Toraja Sapan variety started to gain recognition as native beans of North Toraja. This was followed by the introduction of Toraja Pulu Pulu beans in 2010 and Toraja Yale in 2014.

Dapoer Kopi believes that the company’s biggest strengths are their passion and family background. They are confident that excellence can only be achieved from a solid foundation. Outstanding support from their family and business partners, as well as their extensive experience, all these factors enable them to source the best raw coffee beans – they believe that a good coffee roastery is a roastery that understands its raw materials. They do not consider other roasteries as their competitors, they think of them as their fellow coffee devotees.

Dapoer Kopi truly has Toraja in their hearts. If they had a coffee shop, it would carry the theme of “Welcome to the real Toraja Experiences!” Everything related to North Toraja will be presented in the beverages. And not only coffee, there are a myriad of things to be explored from Toraja. The possibilities are endless.

Dapoer Kopi and Berto Roaster Machine

Berto One was the first Berto commercial roaster machine that Dapoer Kopi ever owned, before Berto’s bigger capacity machines were available in the market. During the period of 2008 – 2012, it was still not easy to source a good quality coffee roasting machine. Dapoer Kopi heard about Berto by word of mouth from a colleague, with high praises as a locally-made roaster machine with an excellent quality. This came as a nice surprise for Dapoer Kopi, but after three years using the Berto machine they found out that the time has come for their coffee roastery to upgrade to a bigger size.

A quote from Dapoer Kopi

What can we say? Simply, trust Indonesian products! The material, build quality, the features are comparable to imported products, the price point is attractive PLUS it is very easy to get after-sales support since the machine is built locally. Berto roaster machines are NOT euphorias without substance, they are real good-quality products dedicated to industrial scale. This means that we can rely on Berto machines in our manufacturing process. Excellent consistency on the roasted coffee beans production, outstanding technical support, and as far as we can tell, Berto always strives to attain perfection. There is no doubt about their commitment to their products and customers. So, do we recommend Berto to support your business? Definitely give it a try! Contact or visit the workshop in Jakarta. You won’t be sorry.

Revoneiro also sells custom blends to other coffee shops or cafe chains, from both its store and online channels. The sale of these custom blends accounts to up to 20% of Renoveiro’s overall sales.

In addition, the company also runs a coffee shop called Ini Kopi. At Ini Kopi, coffee lovers can enjoy great coffee in a relaxed, casual atmosphere. Its best-selling beverage is es susu kopi kocok (coffee milkshake). The shop sells various coffee beans, coffee powder, syrup, and also tea. Buyers can purchase in small quantities, in order to make the coffee more accessible to everybody.

Coffee Future, Revoneiro Style

Revoneiro Roastery has a positive outlook on the future of the coffee industry in Indonesia, as the industry keeps growing each year and also gets more competitive. Iwan believes that farmers are the key to producing good quality beans, as they conduct the entire process from harvesting the red coffee fruit to turning them into dried coffee beans. Excellent quality beans will attract coffee roasters, who will purchase at a premium price. Hence it is important to educate coffee farmers to increase production quality.

Iwan is actively representing Revoneiro in a number of events, from cupping sessions, talk shows, roasting workshops, and many other events in various locations.

Revoneiro and Berto Roaster Machine

Since the first time Iwan saw and tested Berto machine for roasting, he was immediately convinced about the quality of the material, build-up, and the roasting results. Iwan is confident that Berto is an Indonesian-made coffee roasting machine with outstanding quality, supported by an exceptional team.

Revoneiro currently uses three Berto roasters, Berto One, Berto Six, and Berto D12. Another roasting machine, Berto D3 will soon join the roastery as well.

Bayangkan, sekarang anda punya green bean yang hebat dengan score tinggi dan anda juga telah berhasil menyangrainya dengan sempurna. Anda yakin kopi ini akan menjadi favorit. Pertanyaannya, apakah tugas anda sudah selesai? Tantangan anda selanjutnya adalah bagaimana anda bisa mereplikasi profile sangrai juara anda di batch berikutnya, 10 batch berikutnya, atau bahkan 20 dan 30 batch seterusnya.

The Ultimate Goal

Dari sudut pandang pelanggan, hal yang paling menjengkelkan adalah ketika membeli kopi anda untuk kedua kalinya tapi tidak sebaik pembelian pertama. Oleh karena itu, tugas utama anda adalah meroasting biji kopi anda dengan hasil yang konsisten, setiap batch, setiap hari. Konsistensi adalah hal terpenting untuk menjaga brand anda jika anda memutuskan untuk menjalankan bisnis coffee roaster. Brand anda adalah janji kepada pelanggan, dan menjaga konsistensi adalah cara terbaik untuk memenuhi janji tersebut. Dengan menghasilkan produk yang konsisten, barista ataupun pelanggan rumahan anda selalu tau apa yang akan mereka dapatkan dari kopi yang mereka seduh.

Mencapai konsistensi butuh waktu dan usaha. Menyangrai kopi yang baik saja cukup sulit, apalagi melakukannya berkali-kali dengan hasil yang konsisten. Lalu bagaimana kita bisa memastikan hasil roasting kita konsisten dari batch ke batch?

Bagaimana Menjaga Konsistensi?

1. Bikin rencana

Atur tempat kerja anda agar anda bisa bekerja seefisien mungkin. Artinya anda bisa bekerja dengan pergerakan seminim mungkin dimana semua peralatan dan bahan yang digunakan bisa dijangkau dengan mudah, tanpa anda harus banyak pindah tempat. Selain itu, buat rencana roasting (roasting plan), selalu lakukan pengukuran dan cek kualitas green bean sebelum memulai proses roasting.

2. Panaskan mesin sebelum mulai roasting

Memanaskan mesin dengan sempurna sangat penting untuk mencapai konsistensi. Sebelum memulai roasting batch pertama, pastikan suhu mesin mencapai suhu ideal dan pertahankan selama beberapa menit sebelum memasukan kopi ke mesin. Kenali mesin anda agar anda bisa melakukan pengaturan yang sesuai, tujuannya supaya anda bisa mencapai kondisi awal yang konsisten mulai dari batch pertama hingga terakhir.

3. Lakukan PSAB (Prosedur Standar Antar Batch)

Untuk memastikan agat batch berikutnya dimulai dengan kondisi yang sama seperti batch sebelumnya, anda harus membuat dan menjalankan prosedur standar antar batch, kadang disebut between batch protocol. Hal yang umum dilakukan salah satunya adalah mengecilkan atau mematikan burner dan membuka pintu drum. Tujuannya untuk mendinginkan suhu permukaan dan udara dalam drum. Anda bisa juga meningkatkan airflow (aliran udara) sehingga volume udara dingin lebih cepat masuk ruang drum. Setelah suhu mesin turun, hidupkan burner dan panaskan mesin secara perlahan hingga mencapai suhu awal yang diinginkan.
Yang perlu diingat adalah setiap mesin punya sifat heat transfer yang berbeda, sehingga prosedurnyapun pasti berbeda. Apapun sifat mesin dan teknik anda, pastikan anda membuat prosedur standar antar batch dan selalu jalankan dengan disiplin.

4. Pahami sifat heat transfer mesin anda

Anda harus kenali mesin anda, terutama dari sisi heat transfer. Pengetahuan ini sangat membantu dalam membuat prosedur standar antar batch. Selain itu, memahami sifat mesin akan membantu anda melakukan pengaturan parameter selama proses roasting, misalnya: berapa lama sebelum first crack anda harus mengurangi energi burner untuk menghindari flick atau crash? Penyesuaian apa yang harus anda lakukan jika menyangrai di pagi, siang atau malam hari? Jika hujan, apa yang harus dilakukan?

Ada beberapa mesin roasting yang menggunakan teknologi resirkulasi udara, salah satunya Berto tipe R Roaster. Dengan resirkulasi, suhu ruangan dan cuaca tidak banyak berpengaruh terhadap proses roasting anda, karena hampir tidak ada udara sekitar yang dihisap ke dalam drum. Alhasil anda dapat melakukan roasting disegala cuaca dan waktu dan tetap mendapatkan hasil yang konsisten.

5. Rekam dan review lagi data roasting anda

Evaluasi dan lakukan cupping secara teratur, catat susut berat setelah roasting, lakukan sampling acak untuk diinspeksi. Simpan roast log (profile) anda, boleh secara manual (ditulis), atau jika mungkin, gunakan software. Anda bisa review ulang catatan ini untuk melakukan peningkatan di masa depan.
Dengan menggunakan software, anda akan fokus pada proses roasting, tidak perlu memecah konsentrasi untuk melakukan pencatatan. Selain itu, software akan memberi anda pemahaman lebih dalam atas proses roasting yang anda sedang/telah lakukan, yang sebelumnya tidak bisa anda dapatkan dengan pencatatan manual.

Semua mesin Berto bisa dihubungkan dengan komputer sehingga anda bisa melakukan data logging dengan bantuan software. Mesin roasting tipe D Roaster dapat menerima profile yang telah anda simpan dan melakukan pengaturan burner secara otomatis untuk mereplikasi profile tersebut. Di mesin tipe R Roaster, anda dapat menyimpan serangkaian parameter selama proses roasting sehingga, mesin dapat mengulangnya secara otomatis. Kedua fitur otomasi ini memiliki pendekatan yang berbeda, namun dapat membantu anda untuk menjaga konsistensi hasil roasting anda.

You have found a great green coffee and successfully roasted a beautiful batch. You are confident that this coffee will be the star of your business. How can you replicate the result for your next batch, and also the next ten, the next twenty, the next thirty batches after that?

The Ultimate Goal

From a customer’s point of view, there is nothing more frustrating than repeating the purchase of a particular coffee to later find out that the product is not quite the same compared to the previous purchase. Hence the ultimate goal of a coffee roaster is to provide coffee beans with consistently good quality. In fact, it is paramount for a coffee roaster to have a consistent result at every single batch. Consistent results mean baristas and customers are ensured that they will get the same cup every time. Inconsistent results cannot be sold and they cut directly into the roaster’s profit.

However, achieving consistency takes time and effort. Roasting good quality coffee can be hard enough on its own, consistently doing so, again and again, is much harder. How do we measure and ensure consistent roasting on every single batch?

How To Keep It Consistent?

1. Plan ahead

Organize your workspace so you can move around efficiently and find everything you need easily. Before you get started with the roasting process, measure out the green coffee beans for the batches that you will roast for the day, and inspect their quality.

2. Preheat your roaster

Preheating is necessary to ensure consistency. At the beginning of a roasting day, make sure the roaster reaches the ideal roasting temperature and let it idle in that temperature for a few moments before you put the beans in. Ideally, this should be the same condition from the first batch to the last.

3. Make a standardized routine between roasts

To ensure the next batch enters the roaster at the exact same condition as the previous one, it is important to standardize the process between roasts. Make sure the roaster is open for the same amount of time after each batch and to get clean air to flow in. Afterward, preheat the machine and let idle again. The most important thing is to have a set protocol of what to do between roast batches.

4. Understand the heat transfer

You need to really know how your roaster machine performs, not only in its own characteristic but also in relation to the environment (hot or cold climate, humidity, etc).

5. Record and study your roast data

Make sure you cup and evaluate the beans regularly, track the weight loss incurred from the roasting process, and taking random samples of the roasted beans for inspection. Keep a roasting log of all the roasts either manually or with an app. Store all the data in a spreadsheet so you can compare the results over time and aim for improvement.

Our R Roaster machine have a recirculated convection system which means the ambient temperature has minimum impact on the roast temperature, making consistency and repeatability between batches easier to achieve. You can monitor and control everything manually on one screen, with an option to pre-program the roast progress in Recipe mode for a fully automated batch. All of these features mean you can easily achieve the consistency of your roasts. Berto simplifies the roasting process so you can focus on growing your business – and selling great coffee.
