Now when it comes to the same baking color, the baking effect can not be determined what the reason is: 1. The air in this seam has a different thermal conductivity from the beans outside. If it will cause the two temperatures to be different. Most of the problem is that the air inside is much hotter than beans. For example, the oven is too hot, or the beans are not thoroughly dry.

Effect of Powder content on Coffee in Coffee production
1. The concentration determines the richness of the coffee. It is the soluble matter that determines the concentration. (it is worth mentioning that XLW007 in the common sense group mentioned that insoluble substances can also increase the thickness of caffeine. I totally agree, but this time I only focus on the main cause of soluble matter.) generally, the calculation can be measured by the concentration photorefractometer: TDS%= TDS/Coffee Weight.

Coffee roasting principle Fine Coffee basic knowledge of Coffee
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. Conduction of stainless steel
