Share the experience of roasting coffee beans on hand net

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

It takes me a short time to learn how to bake on the Internet, less than 50 nets. When I learn to watch some videos on the Internet, will I ask myself why I want to learn to bake on the Internet? 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 roast coffee beans with excellent fragrance, which is no less than that of commercial professional roasters.

Fourth, 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 do not have any smoke smell, and 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.

I have seen some textbooks that say that in Japan, South Korea and Taiwan, manual web 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.

To put it in a popular way, it is an insurmountable process and stage for any baker to learn to play fine hand web baking.

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.

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.

All in all, if beginners, especially girls, learn mobile network baking, it is strongly recommended that round flat-bottomed hand nets are the most appropriate.
