Description

Kernel and shell separator

Technical Field

The invention relates to a kernel and shell separator which can be used for separating kernel and shell fruits such as sunflower seeds and the like, and belongs to the technical field of food processing equipment.

Background

The sunflower seed oil is golden in color, clear and transparent, has faint scent and is an important edible oil. It contains a large amount of unsaturated fatty acids such as linoleic acid, which are necessary for human body, and can promote the regeneration and growth of human body cells, protect the health of skin, and reduce the accumulation of cholesterol in blood, thus being a high-grade nutrient oil.

The global production of sunflower seed oil generally shows a slow growth trend, the annual average composite growth rate of the global production of sunflower seed oil is 7.72% from 2012 to 2015, and the global production of sunflower seed oil breaks 1700 ten thousand tons in 2018. Ukrainian, russia and the european union are the major countries and regions of sunflower oil production, accounting for around 76% of the total world.

During the production process of sunflower seed oil, sunflower seeds are first shelled by a shelling machine and then enter a kernel-shell separation section to separate kernels from shells. The traditional process of the kernel-shell separation section comprises the following steps: the whole seeds and fine powder are firstly sieved by a plane rotary sieve, a part of the hulls are removed, and the rest kernels containing a small amount of hulls enter the subsequent working section. Because the separation effect of the kernels and the shells is poor, the content of the shells and the shells in the kernels entering the subsequent working section is about 16 percent generally, so that the ideal index proportion cannot be achieved, and because the shells contain a large amount of wax, the quality of the sunflower seed oil is influenced, and the economic index of production and processing is also reduced seriously.
