Steps of roasting coffee beans-detailed diagram of roasting degree

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.

1. Very shallow baking (LIGHT Roast): the degree of baking; very shallow baking, also known as shallow baking. The lightest roasting degree of all roasting stages, the surface of the coffee beans is a light cinnamon color, its taste and aroma are insufficient, this state is almost undrinkable. It is generally used for testing and seldom for tasting.

2. Shallow baking (CINNAMON Roast): baking degree; shallow baking, also known as cinnamon baking. The general baking degree, showing cinnamon color on the appearance, the smell of green has been removed, the aroma is OK, and the acidity is strong, which is a common roasting degree of American coffee.

3. MEDIUM Roast: degree of baking; moderate baking, also known as micro-baking. Medium baking heat and light baking are both American, in addition to sour taste, bitterness also appears, the taste is good. It has moderate aroma, acidity and mellowness, and is often used in the baking of mixed coffee.

4. Medium baking (HIGH Roast): baking degree; moderate micro-deep baking, also known as concentration baking. Belongs to the moderate micro-deep baking, the baking degree is slightly stronger than the slight medium baking, the surface has appeared a little thick brown, the bitterness also becomes stronger. Coffee tastes sour and bitter, with good aroma and flavor, and is most often loved by people in Japan and Central Europe. (blue Mountain Coffee)
