Sand sorting box for apricot pit processing

Abstract

The invention relates to the technical field of apricot kernel processing equipment, and discloses a sand sorting box for apricot pit processing which comprises an apricot pit feeder, a sand feeder, a sand sorting box body, an apricot pit unloader, a sand medium screening and circulating device and a sundry falling bin; wherein the sand sorting box is an inclined container with an opening in the upper portion, the inclination angle is 7-12 degrees, the high-position end is the starting end, and the low-position end is the tail end; an air hole array is arranged at the bottom of the middle section of the sand separation box, and a uniform-pressure air chamber is arranged on the back side of the bottom of the sand sorting box and connected with a fan through a pipeline; and the sand feeder and the apricot pit feeder are sequentially arranged above the starting end of the sand sorting box, the apricot pit unloader is arranged at the upper part of the tail end of the sand sorting box, a sand medium discharge port is formed in the lower part of the tail end of the sand sorting box, the sand medium discharge port is connected with the sand medium screening and circulating device, and the tail end of the sand medium screening and circulating device is connected with the sand feeder. The invention provides equipment capable of completely removing high-hardness impurities in apricot pit raw materials, the service life of related production equipment such as a crusher and a spiral conveyor can be effectively prolonged, and the quality of apricot kernel products is improved.

Description

Technical field: [0001] The invention relates to the technical field of almond processing equipment. Background technique: [0002] When processing almonds, it is necessary to use apricot kernels as raw materials to perform processing steps such as crushing and sieving to obtain products. Before this process, since apricot pits need to be obtained through picking, pulp removal and drying, under the influence of relatively rough picking and transportation tools and drying sites, there are many impurities in the raw materials of apricot pits, including stones, small metal parts such as screws , nuts, etc. [0003] Among the above impurities, there are individuals whose size is close to that of the raw materials of apricot kernels, which cannot be screened out in the primary screening stage. If the apricot kernels enter the subsequent processing process, although they can be screened out by subsequent vibrating screens and wind separators after being crushed, they will not be ...

AI Technical Summary

Problems solved by technology

[0003] Among the above-mentioned impurities, there are individuals whose size is close to that of the raw material of apricot stones, which cannot be screened out in the initial screening stage. If they enter the subsequent processing process with the apricot stones, although they can be screened out by subsequent vibrating screens and wind separators after crushing, other The moving parts such as the blades of the crusher are often damaged during the crushing process, resulting in a reduction in the service life of the equipment. To deal with this problem, a magnet is usually installed at the feed hopper to absorb and remove the iron impurities that are most harmful to the blades of the crusher. , The removal of impurities is not complete. Small stones and non-magnetic metal parts such as copper and aluminum may still damage the crusher. If they are embedded or stuck in the production equipment, it will also cause damage to the almonds obtained from the crushed apricot core, and the product decline in quality
