Coffee roasting heat source heat conduction and convection
At present, the most widely used baking equipment is semi-direct fire (semi-hot air) baking, where the half is only relative to the baking heat source, not the thermal efficiency distribution ratio, such as the probat baking machine we use, in terms of thermal efficiency distribution, it is about 3(direct fire):7(hot air) or 2:8, rather than 5:5. In this article, I try to analyze the characteristics of these two heat sources.

Roasting principle of boutique coffee: heat conduction, convection and radiation
To do a good job in baking, every production link can not be ignored, the selection of materials should be fastidious, the weighing of materials should be accurate, and the operation should be careful. Baking is a science. To understand the principle of baking, we must first understand the three ways of heat conduction, convection and radiation. Conduction refers to when the heat is transmitted by the heat source, causing the surrounding molecules to vibrate and release heat, gradually moving from the high temperature to the low temperature.

American-made Diedrich Roaster coffee roaster introduces infrared coffee roasting technology
American-made Diedrich Raoster general gas-fueled bean roaster uses open fire to heat air or inner pot (drum), metal heat conduction and hot air to bake coffee, which can be roughly divided into three styles: direct fire, semi-hot air (semi-hot air) and full hot air. Although the alternative baking of infrared heater (Infared Burner) combined with steel plate heat exchanger (Heat Exchange) is rare in China.

Maintenance of percolation, drip and vacuum coffee machines
The electric coffee pot is a kind of cooking utensils which uses electric heating to boil water automatically to make coffee. Because coffee is both boiled and brewed, it is only suitable for brewing, otherwise the coffee oil will volatilize in the boiling process and the beverage will lose its aroma and color. The electric coffee maker can meet this special production requirement. According to its structure, the electric coffee pot can be divided into three types: percolation type, drip type and vacuum type.
