The skill of milking in fancy coffee

When filling the steam, you must turn up the steam at one time, so that the steam can blow the milk in the milk tank to form a vortex. To control the temperature of the milk, why is it that if the milk temperature is too high, the effect of milk foam is not good? this is because there is a kind of glue in the milk, which is dissolved at low temperature, and affected by the temperature, the colloid will coagulate and change from the sol state to the sol state.

Coffee roasting principle

Coffee roasting principle

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

A complete knowledge of siphon pot

The working principle of the siphon pot How does it work: the main principle of Syphon is to use the ideal gas equation: PV=nRT, under a fixed volume, heat the boiling water to make the steam pressure of the boiling water, press the boiling water into the upper layer to brew the coffee through the glass tube, and then cool the lower layer in a similar vacuum state to absorb the brewed coffee from the upper layer, and filter the dregs with a filter in the middle. You can take it while looking at it.

Open-box assembly drawing of Huky500 coffee roaster

FRESHROAST SR500 was recommended to me by several friends. It is said that American families use more baking. In addition, they use more household hot air equipment and I-ROAST and NESCO, the price is not much different, between 975-1200 yuan. But the repair rate of NESCO is high, and the baking of I-ROAST is relatively foolish. Relatively speaking, FRESHROAST can support continuous baking (although it can be continuous).
