Mellow is never abstract, because you know where it comes from. For you, fragrant mellow has its own definition and expectations, even if it seems very small, we also know what every bit means to you. You focus on every bit of mellow, we focus on every bit of you.

San Douke Coffee Technology was founded in March 2012, and we couldn't find a coffee roaster that was good enough, so we decided to make it ourselves and make it as a career. Unlike other manufacturers, Sanduke's friends are engineers from the Nuclear Industry and Aerospace Science and Industry Group. We surpass the world's most advanced baking machine. We continue to bring the industry's top technology and the strictest quality control to the design and manufacture of the roaster, which is why our products are so obviously superior to others!

REVOLUTION series coffee roaster

Our current products include two roasters in the revolution series.

They are R500E and R2.5C respectively.

We are familiar with and master the top products and technologies in the industry, and on this basis, we innovate boldly, integrate the latest electronics, materials technology and better design into the products, create a better coffee roaster, and bring technological revolution to coffee roasting, which is also the source of revolution.

R500E and R2.5C are made using the same process, material and technology, and their difference lies in their baking capacity.

We design and name products according to the amount of cooked beans.

The baking capacity of R500E is 100-700g.

The baking capacity of R2.5C is 500-3200g.

Reasons for the Excellence of R500E/R2.5C

Application of temperature curve output software of REVOLUTION series technology and process industry grade

REVOLUTION series technology and technology far infrared inner pot technology, the leap of coffee baking quality

The roaster manufacturers of major brands around the world, whether probat, daichi or Fuji, have been exploring the wonderful application of far-infrared heating technology in coffee roasting. Far-infrared rays can easily penetrate coffee beans. Compared with traditional heating methods, the use of far-infrared technology allows each coffee bean to be heated uniformly and evenly inside and outside during the whole roasting process. Sanduke's latest far-infrared inner pot has been successfully developed! After the heating starts, as the temperature rises, the inner pot will automatically emit far-infrared rays, so that each coffee bean is heated uniformly inside and outside during the whole baking process, thus thoroughly improving the baking efficiency and quality!

世界各大品牌的烘焙机厂商们，无论是probat、daichi还是富士都一直在持续探索远红外加热技术在咖啡烘焙中的奇妙应用。远红外射线能够轻松穿透咖啡豆，相比较与传统的加热方式，使用远红外技术可以让每一颗咖啡豆在整个烘焙过程中内外受热一致、均匀。叁豆客最新的远红外内锅已经成功研发!加热开始之后，随着温度升高，内锅会自动发射出远红外射线，让每一颗咖啡豆在整个烘焙过程中内外受热一致、均匀，彻底提高烘焙效率和质量！

REVOLUTION series technology and technology 16 °/ MIN heat up strongly and burst into rich flavor.

The temperature rise in the baking process is an important indicator, which determines the operating potential of the machine. In the Coe Cup competition, many contestants take rapid temperature-climbing roasting techniques to bake coffee with strong flavor to gain competitive advantage. The limit temperature rise of Fuji can reach 12 degrees, the instantaneous temperature rise of R500E/R2.5 can reach 16 degrees, and the average temperature rise of the whole baking process can reach 13 degrees. So that users can easily bake coffee with rich flavor.

烘焙过程中温升是一个重要指标，决定了机器的操作潜力，COE杯的比赛中参赛选手很多都采取迅速爬温的烘焙手法烘焙出风味强烈的咖啡来取得竞赛优势。富士的极限温升可以达到12度，R500E/R2.5瞬间温升可以提到16度，烘焙整个过程平均温升可以达到13度。让用户能够轻松的烘焙出风味浓郁的咖啡。

REVOLUTION series technology and process 2min rapid cooling, locking flavor

After the baking is completed, it needs to be cooled quickly. In terms of cooling time, the cooling time of commercial roaster is generally about eight minutes after leaving the pot, and the cooling time of R500E/R2.5C is less than 2 minutes, thus quickly locking the flavor.

REVOLUTION series of technology and technology 100 °fine air door, grasp the subtle flavor

Throttle control has a great impact on coffee flavor, throttle control, Fuji is a fixed 5 throttle, for players, such a fixed mode of operation is not satisfied. Therefore, the R500E is a throttle with infinite adjustment, and a 100-gear scale is marked for adjustment. So that enthusiasts can carefully grasp the correct flavor.

REVOLUTION series technology and process top industrial-level temperature measurement and acquisition technology

The error of temperature measurement and the delay of measurement results have always been a taboo in the every minute baking process.

R500E uses the pt100 probe with the highest detection accuracy and the Omron thermometer, the first in the field of industrial temperature collection, to achieve a temperature measurement error of 0.2% (2% for other products of the same class, with a difference of 10 times. If the K-type probe is used, the error will be doubled to 20 times). The temperature feedback period is 5% seconds, and the temperature parameters of the machine feedback are almost zero error and zero delay.

We have not only the detection point of bean temperature, but also the detection point of ambient temperature, which is much more powerful in baking data collection, which provides more sufficient information for your decision-making in baking. More according to your needs to provide inlet air temperature, exhaust air temperature and other detection points to meet your high-end needs!

R500E-X features no shaft inner pot, unlimited surprise

Shaft pot

Shaftless inner pot

We all know that the motion state of coffee beans in the inner pot is the most important parameter of the roaster, which is the most powerful thing in foreign high-quality roasters such as probat. The supporting shaft in the inner pot of small roasters will seriously interfere with the ideal motion curve of coffee beans in the inner pot, resulting in defects in various aspects of the baking flavor. Through perfect design and repeated experiments, we finally realized the design of the shaftless inner pot and realized the ideal movement curve of coffee beans in the inner pot!

R500E has a designed baking capacity of 100-600g. The standard of this design is not only to be able to bake evenly, but also to achieve the most accurate baking temperature feedback and firepower control at this baking capacity! This makes it possible for this machine to meet the needs of individual users to bake a small amount of boutique coffee as well as the daily consumption of small cafes.

Another advantage of this design is that we are the only machine in China that can bake stably and evenly under all baking quantities, whether it is as small as ten grams or much more than the designed baking. only the accuracy of temperature feedback and firepower control during baking will be slightly reduced, but this has little effect on the baking results.

The users of San Douke are as brave as we are, they have made an attempt that we have never done before, baking 900g coffee once, and it has been done many times perfectly!

The far-infrared inner pot technology allows each bean to be heated uniformly inside and outside, and the shaftless inner pot design allows all beans to be heated uniformly and evenly. The two technologies are perfectly integrated to create a unique baking weapon for you!

R500E-X feature Patent Design Simling Tray

There is a basic conflict between the appearance and function of the hand-held cooling tray. The right angle of the square cooling plate is not easy to spill when pouring beans, but the shape is not liked by most users, while the round cooling plate is exquisite in shape but easy to spill out when pouring beans. So we redesigned this product called Simling Tray (smile disk). The top half is covered, leaving an exit for pouring beans, which solves the contradiction between ease of use and exquisite appearance. At the same time, the slotting of the cover plate on the top cover does not affect the air flow and has no effect on the cooling effect. I hope the users of SanDouke will smile when they get the simling tray.
