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.

Measurement and control section

The function description of the control system is shown in the figure. On the 500 model, it seems that only we have the strength to integrate the complete measurement and control system at all costs. The output of the temperature curve only needs a cable and is synchronized with the thermometer of the fuselage.

(PS: there is not much ridicule for those who lack arms and legs to pull wires and patches.)

If the speed of the inner pot is controlled on the left side of the machine, it will not be photographed and will be used when you see it.

In the selection of measurement and control system accessories, when we developed the products, we looked at the existing models. At that time, most of the machines were filled with 50 Taobao thermometers, 10 yuan plastic switches and toggle switches. We chose the Japanese thermometer, the German temperature probe and the control switch of the all-metal ring lamp. (the first sight of it reminds me of BMW's angel eye lights. Then I didn't hesitate to use the best timer available on the market.

Because of the deep shadow left by all kinds of shoddy products in our memory, we have not been able to use these cheap parts on our cherished products in the face of tens of times the cost (it turns out that many of our peers still do not think so at all. .
