The author's hometown is surrounded by endless mountains, so the knowledge of the lotus is mostly from textbooks, which gives birth to many misperceptions. The lotus seeds that I have been exposed to in the past are dried lotus seeds, and the subconsciously think that the lotus seeds are white. Flowers have no outer shell.
Until I saw someone selling the lotus on the market, the author was only stunned by the conversation. On the surface, the lotus was sold. The actual sale was fresh lotus seeds. 'When peeling the lotus seeds, the lotus seeds must be pulled out from the lotus hole and then green. Peeling off the skin is a lotus seed, but the green skin is very tender, and it will hurt the lotus seed if you accidentally. 'The grandmother tells the author. The operation of selling the grandmother is so difficult, the lotus seeds on the market are catching a lot. I don’t always want to peel it out by hand. What kind of food machinery and equipment behind the shelled lotus seeds makes the author very curious.
Outside the lotus seeds, not only the lotus, the outer skin, but also a layer of lotus clothes. The conformity and size of the three shells are different, so to get the lotus seeds, you need to take off the shell three times. The first thing to go is the lotus. The outer shell, the lotus thresher is a device that separates the lotus from the lotus. The lotus thresher starts to rotate after the lotus enters, and uses the centrifugal force to separate the lotus and the lotus, and then produces the lotus. In the treatment of the lotus, such equipment There are two different treatment methods, one is to crush the lotus, the other does not do any treatment on the lotus. You can choose equipment according to the subsequent use of the lotus.
After the threshing, the lotus seedlings with green skin need to be shelled. At present, some lotus seedling machines are mechanized in the working procedure and are not equipped with smart equipment. Therefore, it is impossible to adjust the parameters of the shelling equipment according to the size of the lotus seeds. This means that the lotus seeds need to be used. In the early stage of shelling, the size of the lotus seeds is sorted. The equipment for sorting food size is simple in structure and the equipment is relatively mature. The lotus seed particle screening machine sets different apertures through the machine, and then rotates and advances. 3. The shock and other methods make the lotus movement, and screen out the size.
Taking off the outer layer of lotus seeds is the shelling process we often say. Shelling has been in the stage of manual labor for a long time. In view of the fact that the lotus seed shell is hard, one worker needs a blade to open the lotus shell, and another worker carries out the shelling operation. The process is more cumbersome. At a time when labor costs are rising, it is a big problem for many enterprises to shell the lotus seeds. The lotus seedling machine is generated for this phenomenon. The equipment generally uses a blade to open the lotus seed shell, according to the blade movement. The difference in form can be divided into rotary lotus sheller, linear lotus sheller, etc. Then use centrifugal force, sputum and other means to remove the lotus shell.
Of course, the lotus seed is not the last step after removing the two-layer shell. The fresh lotus seeds also have a layer of transparent skin. This layer of belt has a bitter taste similar to that of the lotus heart. It is not popular for most people. Therefore, to get the lotus seeds we buy every day. It is also necessary to remove this layer of skin. The lotus seedless machine is produced under this condition. This layer of skin is more transparent and soft. The removal method includes high-pressure water washing, grinding wheel grinding, etc. It is understood that the equipment is soft and does not damage the lotus meat. The basic requirements of the equipment, therefore, the size of the water pressure, the length of the grinding time, etc. need to be adjusted.
With the enhancement of equipment integration, a lotus peeling and peeling machine has emerged, which has a peeling effect while the lotus seeds are shelled. This device greatly speeds up the peeling and peeling efficiency of the lotus seeds and reduces the space occupied by the equipment. It is more popular in the primary processing stage.
It can be seen that even the lotus seeds that can often be seen in daily life, its production is not simple, and it needs to go through many processes such as shell breaking, sorting, peeling, etc. In the initial processing of food, there are many Such foods need to carry out cumbersome processing, how to simplify these processes, and design related equipment that meets market demand is a major problem that food machinery equipment manufacturers need to consider.
