The steps of roasting coffee beans-introduction to the roasting degree and price of coffee beans
The choice of the material of the inner pot is the most tangled place when making the product. in the initial design, because the stainless steel material can be rolled up and welded, it is convenient to manufacture, while the cast iron material has a great initial investment, so stainless steel has become a very tempting choice. but after the test, it is found that the stainless steel inner pot can not evenly transfer heat to the whole inner pot, resulting in some points that will overheat and scald coffee beans. A good stainless steel pot is a composite structure, with more than three layers at the bottom, with an outer layer of stainless steel at the bottom, with a copper plate in the middle as an important heat conduction layer to disperse the uneven heat energy at the bottom of the pot, so that the internal stainless steel layer can be heated evenly. But this kind of technical solution is used in the inner pot of the roaster, we really can't do it.) (PS: the three-layer structure requires a large punch to integrate the structure and exhaust air. Moreover, what people do is a flat plate, and the roaster is an inner pot.)
So after spending almost all the money at that time, we made the R500 series cast iron inner pot out of cast iron, which is still in use today.
The material of cast iron made the inner pot of R500 reach the same material level as most imported models, and we were proud of it for a long time until we learned about plasma spraying technology.
Far-infrared materials are widely used in the food industry, but no one has ever tried to use it in the harsh environment of a roaster. The change of temperature difference, inner pot expansion, friction and coffee bean impact all pose challenges for us. Until we tried to use plasma spraying technology to firmly attach ceramic far-infrared materials to the inner pot, this problem was still solved. Knocking and friction will not destroy its structure.
About the use of sampling spoon
The small roaster is easily affected by the environment, the mouth of the sampling spoon will be a channel for cold air to enter when pulled out, and the proportion of such channel and intake to the whole pot will be relatively large in the model 500. therefore, when operating the sampling spoon, it is recommended to take the way in the figure, not completely pulled out, at the same time, R500 adjustable led spotlights can help you to observe the spread of the bean watch and the change of color.
Similarly, the lower glass observation window is also chamfered to 45 degrees, such details can provide a better visual experience.
Cooling piece
It is easy to cool down the beans, but it takes a few seconds for the fan to run at full speed, so it will be better to turn on the fan in advance before preparing to leave the pot.

The flavor description characteristics of Colombian Jindio coffee beans, the taste of the manor region introduces the world coffee is divided into two series, one is the hard coffee represented by Brazil, which has a strong flavor, and the other is the soft coffee represented by Colombia, which has a light flavor. The difference lies in the altitude of the producing area and the method of planting. Coffee is grown extensively in hilly red soil in Brazil and in mountains in Colombia.
