Introduction to the process of dehydration in coffee roasting process controlled by throttle

In addition, when it comes to the problem of oil production of beans, the more fat we drink, the better the taste, while the beans with less oil are thin and boring, but do we have to see oil in roasted beans?

This is not the case, and the oil from baked beans is not bad, the most obvious period of oil production during baking falls at 233 degrees Celsius, when it is very easy to produce oil.

As long as the fire is not added or turned off and the throttle is opened so that the boiler is stable at about 230 degrees and does not rise, the baked beans can continue to explode to the middle and back section without oil.

If the temperature is not properly controlled, the baked beans will produce a lot of oil, so drink it as soon as possible in a few days to avoid excessive oxidation to "oil shit smell."

Baking utensils: hand net hot fan electric heating machine gas baking machine

Hand net is the easiest and cheapest appliance, the baking process can be achieved by using the gas stove at home, and the baking quality depends entirely on experience and hand feeling and arm strength.

It is open baking can not do the lock temperature, and can not measure the temperature of beans, please pay more attention to the fluency of the popping sound (neither urgent nor slow).

Hot fan this is a love and hate roaster: a simple household machine I Roster & GENE 3D is cheap and easy to operate.

Korean-made or Taiwan-made self-baking professional hot fans cost tens of thousands of yuan per 500g 1kg, while Germany's top automatic hot fans cost more than 600,000 yuan at 30kg level.

The advantage is that the hot fan is very suitable for baking beans with high water content, but the aged beans with low water content will not achieve the best flavor of baking, but the baked beans sell well.

The electric heater (direct fire type) is the safest and most environmentally friendly, and there is no open fire limit, which can best meet the requirements of urban management in the market. the effect of a good electric heater is no worse than that of a gas-type roaster.

Gas machine is divided into direct fire type and semi-direct fire type: it is relatively easy to operate the semi-direct fire roaster, also known as semi-hot air roaster, the baking flavor is good.

Direct-fired gas machine is very testing the experience of bakers, improper operation of baked beans is prone to uneven baking, charred beans are also obvious, but good baking is delicious in the world.

The four stages of the baking process: dehydration, saccharification, bursting, carbonization.

The rhythm of the fire source you can control: medium fire, warm fire, slow fire, small fire glide (actually turn off the fire)

You can also use the throttle to control the drainage and smoke discharge and timely adjust the baking effect of the thermal energy system of the oven.

The machine baking has the temperature locking effect of the boiler, but the hand net is open and can not lock the temperature. Lowering the fire is an unnecessary action, but pay more attention to the fluency of the bursting sound (neither urgent nor slow).

There is a way to do it in baking: stretch

That is the use of the rhythm of the big fire and small fire to control the climbing temperature fast and slow, the condition is not to lose the temperature, used before and after the burst period.

It can achieve the integrity of saccharification and the stretching of the bean surface without irritating taste.

PS. If the coffee tastes good, you should pay more attention to the appearance of the coffee. Erpei's look is good, but the flavor is worse.
