technical field

The invention relates to the technical field of agricultural machining, in particular to a flexible hitting and extruding walnut shell breaking device. the

Background technique

At present, China's walnut production ranks first in the world. Although China is a large walnut producing country in the world, it is not a powerful walnut producing country. The mechanization of walnut processing in my country is less than 10%. Most of the cracked walnut shells in my country are still artificially cracked. Manual cracking of shells is labor-intensive and inefficient, and the pollution index is high, which affects the quality of walnuts. The export cannot meet the standards, which greatly reduces the added value of walnuts. the

Walnut kernels have high nutritional value and contain a lot of protein and fat. Moreover, walnut kernels also contain essential amino acids, vitamins, and trace elements for the human body. Walnuts are suitable for deep processing. 80% of the walnuts in developed countries are put into the market in the form of deep processing. China’s deep processing capacity for walnuts is seriously insufficient, and the processing level is low, which not only makes the added value of products low, but also greatly affects the international trade of Chinese walnuts. Advantage. the

There are various shell breaking machines on the market now, but their effects are not ideal, and there are still some problems, which are manifested as incomplete shell breaking, low shell breaking rate, and low high road kernel rate, mainly in the shell breaking rate. And the high road kernel rate can not meet the requirements of industrial production. This has just greatly reduced the sale of walnut kernel, has also just reduced the commercial value of walnut. So now there is an urgent need for an effective shell breaking device to improve the shell breaking rate and high kernel rate, so as to speed up the mechanization of walnut processing. the
