Nut shelling and sorting machine

Abstract

The invention provides a nut shelling and sorting machine which comprises a housing case, a housing case cover, a feeding mechanism, a cracking mechanism and a separating mechanism. The feeding mechanism comprises a feeding hopper and a rotary evening rod; the cracking mechanism comprises fixed and rotary scrubbing squeezing discs, damping springs, adjusting bolts, a motor, a motor shaft and a motor support frame, and the fixed and rotary scrubbing squeezing discs are respectively provided with rubber scrubbing layers; a scrubbing squeezing channel with a gradually reduced gap is outwardly formed between the two rubber scrubbing layers, and the size of the gap at an outlet of the scrubbing squeezing channel is slightly larger than the average diameter of nuts; the separating mechanism comprises air inlet pipes, an annular blow pipe, a distributing hopper, a crushed shell discharge hopper, a kernel buffer nut, a kernel passing plate and a kernel discharge outlet; and the kernel buffer net is annularly and fixedly mounted along the inner wall of the housing case. Compared with the prior art, the nut shelling and sorting machine has the advantages of capabilities of uniformly and orderly feeding the nuts and thoroughly separating kernels from shells, and high shelling efficiency and kernel completeness rate.

Description

technical field [0001] The invention relates to a nut shelling machine, which belongs to the field of food processing machinery and equipment. Background technique [0002] Pine nuts, apricot stones, hazelnuts, ginkgo, etc. are difficult to shell due to their hard shells and irregular shapes. In the prior art, the shelling of such nuts mainly adopts the centrifugal collision method and the extrusion crushing method. The centrifugal collision method is to use the centrifugal force to throw nuts at high speed and collide with the body. This method has a low shell breaking rate, especially for apricot kernels with hard shells, pine nuts, etc. The shell breaking rate is only 10-20% at a time, and the nuts are broken. High rate. [0003] The squeeze crushing method is to utilize nuts to pass through a certain gap, and the nuts are crushed under pressure. For example, the authorized notification number is CN2011945359Y, which discloses a nut shelling machine, which includes a fee...

AI Technical Summary

Problems solved by technology

And because the nuts are piled up randomly at the feeding port, the nuts will collide with each other at the feeding port driven by the high-speed rotation of the dynamic friction wheel, which will affect the smooth entry of the nuts into the friction channel, and they cannot be evenly distributed between the fixed and dynamic friction wheels. It intensifies the cutting and collision of the broken shell on the nut, reduces the integrity rate of the nut, and also reduces the efficiency of the broken shell of the nut

At the same time, because the discharge port is not equipped with a shock absorbing device, the flying nuts will collide with the wall of the discharge bin, which will also reduce the integrity rate of the nuts
