Coffee machine: the principle of single boiler heat exchanger

Sky.zhaoyao 's coffee machine: the principle of a single boiler heat exchange since Luigi Bezzera launched the first commercial coffee machine with steam pressure in 1901, whether it is the Pavoni Gaggia or other machines that use steam or pistons as pressure, there is only one boiler: the bottom of the boiler is the hot water for brewing coffee, and the top provides steam, but in order to produce steam, the whole

The principle of coffee bean roaster the knowledge that coffee roasters must see

Baking is an esoteric 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. The conduction of stainless steel has the phenomenon of uneven heating, which can easily lead to colder and hotter parts of the pot.

Basic knowledge of high-quality coffee the principle of weight loss and weight loss of coffee

Coffee is a symbol of taste, fashion and cozy life, and its Fangchun is indispensable in the city. Now more and more people have the habit of drinking coffee, not only do they like it, but also some people use coffee to lose weight. Let's take a look at the principle of caffeine weight loss. 1.

Several practical principles for judging coffee how to express the flavor of coffee

The working principle and usage of Belgian 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 through the middle filter. You can enjoy the coffee while watching the extraction process.

General knowledge of boutique coffee ice drop coffee water drop coffee the latest coffee principle introduction and information

The principle of ice-brewed coffee is that the coffee itself is compatible with water and is extracted bit by bit by melting ice. The coffee extracted has different flavor according to the roasting degree, water quantity, water temperature, droplet speed, grinding thickness and other factors. Coffee powder is 100% soaked in low temperature and moist, and the extracted coffee has a strong, smooth and rich taste, which is admirable.

The main principle of Syphon is to use the ideal gas equation: PV=nRT, under a fixed volume, heat the steam pressure of boiling water, press boiling water into the upper layer to brew coffee through a glass tube, and then cool the lower layer in a vacuum-like state to absorb the coffee already brewed in the upper layer, and filter the dregs through a filter in the middle. You can enjoy the coffee while watching the picking process, which is the charm of syphon.

Coffee brewing method: a detailed introduction of the principle and characteristics of the French kettle

The principle of the pressure pot: the essence of coffee is released by soaking and stewing through the full contact between water and coffee powder. The characteristics of the French kettle: [not expensive! No consumables] take the French pressure of HARIO heat-resistant glass, which is the best quality on the market, as an example, the market price of the basic style is only a few hundred yuan, and it does not need consumable materials such as filter paper.

The principle of ice-brewed coffee is that ice-brewed coffee is extracted bit by bit by melting ice due to the compatibility of coffee with water. The coffee extracted has different flavor according to the roasting degree, water quantity, water temperature, droplet speed, grinding thickness and other factors. The characteristic coffee powder is 100% soaked at low temperature and moist, and the extracted coffee has a strong, smooth and rich taste.

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.
