Physical strength and flexible helical blade-coupled walnut shell and kernel drum two-way separation equipment

Abstract

The invention relates to physical strength and flexible helical blade-coupled walnut shell and kernel drum two-way separation equipment, which is high in automation degree and consistent with food safety regulations and has a walnut shell and kernel separation function. The equipment comprises a helical blade drum arranged on a support structure, wherein a concentric main shaft is arranged in the helical blade drum; the two ends of the main shaft are arranged on the support structure through respective bearings; the main shaft is connected with a power source; helical blades I, II and III are also arranged on the main shaft, and are coupled to one another to form a continuous variable pitch helical conveying blade mechanism, thereby dividing the helical blade drum into three working areas, i.e. a walnut shell conveying area, a walnut and kernel separation area and a walnut kernel conveying area, which correspond to the helical blades I, II and III respectively; an inlet of the helical blade drum is connected with a feed hopper, and meanwhile, an air blower and a walnut kernel collector are also arranged at the inlet; a walnut shell collector is arranged at an outlet of the helical blade drum.

Description

technical field [0001] The invention relates to an automatic separation process and equipment for walnut shells and kernels, in particular to a two-way separation equipment for walnut shells and kernels rollers coupled by air force and flexible spiral blades. Background technique [0002] In order to realize the mechanical automation of walnut shelling and kernel extraction, walnut shell kernel separators have been developed both at home and abroad. The existing walnut shell kernel separators generally use the principle of air separation, magnetic separation, and wet scraper principles. [0003] The air separation type and the wet scraper type use the difference in the specific gravity of the walnut shell kernel to separate the shell kernel. The specific gravity of walnut shell is 1.2-1.4, and that of walnut kernel is about 1.02. When the difference in specific gravity is small, although the separation rate of thin-skinned walnuts is relatively high, the separation effect o...

AI Technical Summary

Problems solved by technology

The main disadvantages are: the walnut inner shell floats on the liquid surface and is difficult to separate from the walnut kernel; it needs washing, drying and other post-separation treatment, which increases the processing cost and prolongs the processing cycle, and the efficiency is not high

However, the main disadvantages of using iron powder and magnetic powder as additives for processing walnuts are: increased processing costs, and also caused pollution to walnut kernels

This method is a typical wet separation method, which has a long working cycle and needs to stand for a period of time before it can be separated; the degree of automation is low, and it needs to be used with a screening machine or screen; post-processing (washing, drying, etc.) is required. increased processing costs

[0007] Although people have developed a variety of automatic separation devices for walnut shells and kernels to separate walnut shells, each device has its own advantages and disadvantages, and it cannot completely clean and automate the separation of walnut kernels.
