In a household roaster, it becomes quite easy to bake coffee beans by yourself.

Household baking machine

In recent years, there has been an upsurge of roasting a small amount of coffee beans, and there are many household roasters on the market, and it has become quite simple to roast coffee beans by themselves. At present, household roasters can be divided into three types: self-ignition type, hot air type and drum type. Although these are not very sophisticated professional models, as long as they are handled properly, the roasted coffee beans are still mellow.

1. Direct firing: ceramic roaster or pan

Direct-fired appliances are the simplest and can be pans or Japanese-made long-handle ceramic roasters. The ceramic roaster is closed, has the effect of stewing, and can bake coffee with delicious and complex taste; its taste is the most natural and thick. Nowadays, this kind of ceramic roaster is often available outside Japan. The effect of the pan is not good, so it is not recommended to use this appliance.

The baking method of the ceramic roaster is very simple, first put the raw beans into the pot, and then shake the long handle on the gas stove. The baker can control the firepower and the baking time by himself.

The disadvantage of this tool is that there is no hot air to blow off the silver film and debris, so it is more likely to smell. In addition, it has no cooling function. After baking, you have to pour the beans into a basket and cool them with a fan or electric fan.

2. Hot air type: hot air type popcorn machine or hot air type household roaster

The hot air popcorn machine was originally used for popcorn, but then someone used it to bake coffee beans, and it worked well, and it was all the rage for a while. Its disadvantages are: it does not have the function of collecting debris, the hot air makes the debris film fly everywhere, and it takes effort to clean it up afterwards; and the heating speed is so fast that the first burst can be heard in about 4-5 minutes, the water does not completely evaporate, and the taste is not full enough. Slightly sour. The popcorn machine can bake 100 grams of raw beans at a time, but not enough or too much. It does not have the function of automatic shutdown, so you have to look after it when you use it, otherwise it may burn the whole pot of beans.

In areas where coffee is popular, these machines can be bought in coffee stores or websites. When in use, as long as the raw beans are put in, the baking degree is set, and the start button is pressed, which is completed automatically from baking to cooling.

Hot air household roasters have the function of collecting debris and cooling, which can produce clean baked beans. The ideal baking degree setting should be to judge the temperature and then stop baking automatically. However, the baking degree setting function of these machines is just a timer, and when the time is up, it will automatically switch to the cooling phase. Because the temperature in winter is very different from that in summer, and the time required to bake coffee is also different, there may be a difference of more than one scale when setting the roasting scale.
