The roasting procedure of high-quality coffee learning coffee roasting

The roasting procedure of high-quality coffee learning coffee roasting

Coffee roasting is the coking of raw coffee beans at high temperature. Roasting completely changes the substances inside the raw beans to produce new compounds, which are recombined to form aroma and mellow flavor. And this effect will only happen at high temperature, if you only use low temperature, it will not cause decomposition, no matter how long the coffee beans are not cooked. Most people think that baking is nothing, just using firefighters.

Structure diagram and roasting operation of Huky500 coffee roaster

It has been three years since the publication of Huky300. Over the past three years, I have known a lot of coffee friends, and I have also received advice from many friends on Huky300. I happened to have the experience of helping my friend Yang change the drum by one kilogram last month. I thought that maybe I should also make some changes for Huky300. After more than a month of conception, design, and trial production, the final edition was finally finalized. The main changes this time are: 1. The inner tube is enlarged and the mixing sheet is increased.

The brewed coffee can retain its flavor for a long time by lowering the temperature immediately.

Experiment on how the flavor of brewed coffee changes when it is frozen and cooled to room temperature. First, prepare two cups, and 100ml's ice (ice in the back is ice) pour the coffee liquid from the hands into two cups, each 80ml add 100ml ice on the left and the same amount of hot water on the right. (that is to say, the cup on the left will drop to several degrees in an instant, and the right will continue to protect it.

I, when heated, is converted into isomers cellulose III and cellulose IV. The structure of coffee is a well-developed matrix, which improves the consistency of quality and contributes to the uniform spread of heat during baking. Cellulose in coffee is embedded in lignocellulose (an amorphous matrix containing hemicellulose and cellulose-containing lignin).
