Practical information: can you play hand-net baking?

I have been learning coffee bean hand network roasting for more than two years, and I have roasted more than a hundred nets. During this period, I have consulted some professional roasters in China and Taiwan from time to time. I have received a lot of advice and correction from them, because I have always had respect for coffee roasting. So I didn't dare to post the first post about hand net baking until now.

Do you ask yourself why you want to learn mobile web baking? As far as coffee lovers are concerned, mobile web baking has at least several benefits:

First, the mobile network is cheap, small, flexible and does not take up space. You do not need to buy an expensive, complex and occupied roaster, so you can enjoy the fun of roasting coffee and master the whole process of roasting, grinding and making coffee.

Second, in terms of individuals, families or a small number of friends, the amount of coffee baked by the hand network can fully meet the communication needs of themselves, family and friends; the roaster has a large amount of baking at one time, as far as individuals or families are concerned, if you can't consume it in a short time, it's a big waste.

Third, compared with precision instrument control and automatic roaster, hand net baking depends on the accumulation of physical and mental experience and practical operation experience, and gets more fun in the baking process. According to Taguchi and many roasters at home and abroad, manual roasting can not only observe and experience every step and different changes of coffee beans in the whole process, skilled technical operators can also bake coffee beans with excellent fragrance no less than those of commercial professional roasters.

Fourth, hand net baking has unique advantages compared with roaster. What advantage? We know that whether direct fire, semi-direct fire, hot air or electric baking, etc., although modern instruments + modularization + computer precision control, despite accurate temperature control, ventilation, cooling and other equipment, however, because a large number of coffee beans are rolled and stir-fried in a relatively small closed container, it is inevitable to be contaminated with smoke more or less during the baking process. This is the biggest problem that many baking masters can hardly avoid completely. The biggest advantage of hand-net baking is that the whole baking process is an open environment, although silver skin flying everywhere is annoying, but this is also one of its greatest advantages, so the coffee beans baked by hand-net are very pure and have no smoke smell at all. The best coffee beans can be baked with the most primitive tools. I have seen some people use edible "foil" to wrap the hand net up and bake, but this loses the advantage of the hand net. It is very easy to cause smoke and smells. Japan's Taguchi is recognized as a baking master, who has developed a world-class professional roaster, but his favorite at home is mobile network baking.

Fifth, the small amount of hand-net baking is its deficiency, but it is also an advantage. Like small-pot cooking, it is easier to master than large-pot cooking, while small-pot cooking is always more delicious than big pot, oh, a small amount is not afraid of failure and repetition, all kinds of beans and different baking degrees can be tried, with the accumulation of experience and lessons, the effect of your hand-net baking will become better and better.

In Japan, South Korea and Taiwan, manual roasting is an indispensable process for any professional roaster. Coffee roasters often say: if you can't even bake or bake well, let alone operate a professional and complex roaster.

It can be said like this: learning to play fine hand network baking is an insurmountable process and stage for any baker.

▲, these delicious coffee beans are all baked on my hand net.

Although the baking tool of ▲ hand net is very simple, it can also bake rich and delicious coffee beans.

▲ Japanese Sanxue three Snow flat-bottomed hand net (diameter 15cm), electronic weighing one, stainless steel bowl sieve (called beans or lower beans can be used), 20-mesh stainless steel flat screen (special for cooling beans, because of the large flat bottom area, blowing from bottom to top with electric fan, the cooling effect is better), a pair of gloves, a small desktop fan (electric wind can also be used).

▲ Yega Xuefei and Yunnan Iron pickup are easy to bake beans.

▲ hand-selected to remove defective beans and beans that are too big or too small to make the beans as uniform as possible.

▲ every time I bake is a fixed 100g, never too much (the reason is related to the area of the hand net).

▲ pours the good coffee beans into the flat-bottomed hand net.

▲ this mobile network is the Japanese Mixue Three Snow.

Flame size of ▲ 's initial dehydration

When the ▲ dehydration ends in 7 minutes, the beans turn light yellow. At this time, the temperature can be slightly increased to allow the beans to enter 1 burst.

▲ as the temperature rises, around 200C, as the color of the beans begins to change rapidly, the smell becomes stronger, indicating that the beans are about to enter a period of explosion, because the beans themselves will release heat at the same time, so shake the hand net quickly and make the beans roll evenly.

▲ with the sound from messy to dense, from dense to messy, slowly there is no sound, and the sweet smell in the smell is stronger, which means that the explosion is over. I like the taste of this bean after the first explosion and before the second explosion, so keep the original flame, pull the distance between the hand net and the stove slightly higher, and continue baking for 2 minutes.

What is special about the Japanese Sanxue hand net is that it makes several protrusions at the bottom of the roasting net. When gently shaking the roasting net from side to side, the coffee beans will tumble and change position because of the grooves, so that the heat is more uniform. The position of roasted net coffee beans without grooves is difficult to change easily.

I think it is very important that many friends have a big misunderstanding on how to choose the handnet correctly, and even lead to the great misunderstanding of the opponent's network baking itself.

I have seen many times that the domestic use of two semicircular stainless steel leakage mesh combined into a circular hand net, in Taobao also has similar spherical hand net sales, the price is very cheap. While Japanese hand nets are round and flat-bottomed, but the price is also relatively expensive, so many friends choose cheap spherical hand nets.

However, after my practice and repeated comparison of the two kinds of hand nets, I think that the round flat bottom is the best for hand net baking for the following reasons:

The flat-bottomed hand net can spread the beans evenly, and can shake and flip the beans with very light wrist strength, so girls and people with weak physical strength can also easily operate and bake them.

Because the flat-bottomed hand net is a neat horizontal plane, which is consistent with the fire source of the circular plane, the heating area is relatively uniform, and the phenomenon of uneven frying is not easy to occur.

The flat-bottomed hand net has a large area and is heated evenly, and the color of the baked beans is basically the same.

This emphasis is not to say that round hand nets cannot bake coffee, but compared with flat-bottomed hand nets, spherical hand nets obviously have the following fatal weaknesses or serious deficiencies:

First, because the bottom is semicircular, coffee beans can not be evenly laid, so a lot of beans have to be piled up, which in itself is not conducive to hand-net baking.

Second, in the process of baking, in order to heat each coffee bean evenly, a simple horizontal rotation and shaking like a flat-bottomed hand net will not work. It must be vigorously bumped up and down and shake to make the coffee beans heated evenly as far as possible. Some friends who love hand nets even invented the word "spoon", but in this way, the whole baking process will become quite physically exhausting. Only strong men can be competent, and it is difficult for girls to do so with their weak physical strength and wrist strength.

I once watched a video baked by a domestic ball-shaped hand net. The strong man had super physical strength, and his hands clenched the ball-shaped hand net and shook it vigorously all the time, which left a deep terrorist impression on my opponent's net baking. through the exchange with foreign friends who specialize in baking and my personal practice over the past two years, I found that this is actually a great misunderstanding of the opponent's net baking. In fact, it is the mistake of the hand net tool that leads to the mistake in the understanding of the opponent's net baking. Correct hand web baking is not as brute force consuming as seen in many domestic materials and videos. Hand net baking is not only the privilege of strong men, but also the ability of weak women to play hand net baking.

Third, because the bottom of the round spherical hand net is a hemispherical, which makes the heating area of coffee beans is not on a horizontal plane, the area close to the heat source is small, and the distance is also near and far, so the beans are heated unevenly. Frying class and inequality will occur if you don't pay attention to it. And from the strange shape of the spherical hand net, it can not bake as horizontally as the flat-bottomed hand net, nor can it rotate smoothly on a fixed bracket like a drum, and keep bumping up and down vigorously to drive the fierce flow of air near the source of fire, which will not only destroy the original steady firepower, but also make the temperature of beans go up and down in the fierce jolts, unable to steadily heat up or cool down.

Through the comparative practice and in-depth analysis of Japanese round flat-bottomed and domestic round-bottomed spherical hand nets, it is believed that those who like baking can draw scientific and correct conclusions. Therefore, if beginners, especially girls, learn to bake hand nets, it is strongly recommended that round flat-bottomed hand nets are the most appropriate.
