The walnut shell breaking machine is based on the principle of three-point rolling crushing. The half kernel rate of the walnuts after being broken by our company's walnut shell breaking machine can reach about 60-70% (the walnut varieties at this time are required to be thin-shelled, and The water content is 10-12%). The yield of 1/4 kernels accounts for less than 25-35%, and the yield of 1/8 kernels accounts for about 5%. The overall loss rate (the loss rate is related to the water content of walnuts, the higher the water content, the lower the loss rate) is. To 1%, generally around 0.4--0.5% (at this time the water content is 12-15%). The loss rate of walnuts is lower than that of manual walnuts. The product is divided into 1/2 kernel (between the sieve hole of 20mm×30mm and the sieve hole of ∮15mm), 1/4 kernel (between the sieve hole of ∮15mm and the sieve hole of ∮10mm) and broken kernel, namely 1 /8 (less than ∮10mm mesh), the output rate of walnut kernels depends on different walnut varieties, and the shell content in the kernels and the proportion of each kernel are related to the walnut variety, water content, etc. , no specific standard. This production line can only process thin-skinned walnuts: that is, after the walnuts are broken, the shell kernels will naturally disperse, no kernels are stuck in the shell, and the inner diaphragm is relatively loose, which is conducive to taking kernels, similar to the Xinjiang 185 walnut variety. So this machine is the ideal advanced shell breaking equipment.

2. Features of shell kernel separator:

   Our company's shell and kernel separation equipment adopts the air separation technology. All the shell and kernel mixtures are firstly separated. During this separation process, the larger shells are separated first, and the separation can be guaranteed. The shell does not contain kernels. Then the husk kernel mixture is classified and divided into 1/2, 1/4, and 1/8 three-way husk kernel mixture. The air volume is adjustable to ensure that the shell is separated and contains almost no kernels. There is little shell in the separated kernel, even if there is a small amount of shell, it can be simply selected by one person. During the classification of the shell and kernel mixture, in addition to being divided into 1/2, 1/4, and 1/8 three-way shell and kernel mixture, there are unbroken and complete walnuts and whole kernels from the end of the classification. It is then sent to the secondary crusher through the sorting conveyor for crushing and then returned to the discharge end of the primary crusher. If the whole kernels from the end of the classification are manually picked up by the sorting conveyor, a certain amount of whole kernels can be collected. Benevolence. Therefore, this machine is the shell and kernel separation equipment with the current separation effect.
