Roasting technology of coffee beans: introduction to the operation of roasting coffee with hand net
Hand net is one of the important tools for many coffee lovers to bake by themselves. it is cheap and convenient. A hand net plus gas at home can complete the whole process, and a domestic fake hand net is only a few dozen yuan. The amount of baking is about 100 grams at a time.
However, hand net baking also has fatal disadvantages, because it is not professional equipment, the control of fire depends entirely on personal experience to control the distance from the fire source, the baking process may be up to nearly 20 minutes, for personal arm strength is also a test, the chance of baking is high.
The hand net is also a starting point for me to start baking. I suddenly turned it out last night and suddenly wanted to play, so I tried it.
More than 100g bird of paradise sigri, very good beans.
Nearly 7 minutes into a burst, 1 explosion time is about a little more than 2 minutes, nearly 12 minutes under the beans, did not enter the second explosion.
Beans evenness is OK, did not enter the second explosion, the taste is bright, light fruit aroma, taste clean, if not said to be birds of paradise, you certainly do not know when you drink Asian beans, of course, this is my own drink, if friends want birds of paradise I will still touch the second explosion, during this period of time found that most of the domestic friends still prefer balanced taste of beans, or stay away from the sour aroma.
As for the hand net, it really feels like a good toy, the price is not expensive, and it is good to play with it, but if you are a friend who often drinks coffee, the hand net is probably very troublesome for you, the baking quantity is small and the stability is relatively poor.

Recently, I have found that more and more friends use quasi-professional Italian machines to make coffee, including Oscar, Silvier, and E61 small machines for head cooking, but when I ask them how to clean and maintain them, many people are surprised. Some friends do backflushing regularly, but they don't clean the water distribution network. In fact, the Italian machine is a rather skinny guy.
