Kernel-hull separating system of sunflower seeds

Abstract

The invention relates to a kernel-hull separating system of sunflower seeds. The kernel-hull separating system comprises a hulling machine, a kernel-hull separating machine and a multi-stage air separator. A discharging opening of the hulling machine is connected with a separating machine feeding opening of the kernel-hull separating machine through a hulling discharging chute. The kernel-hull separating machine is provided with an integral seed outlet, a fine powder discharging opening, a seed kernel discharging opening, a top suction outlet and a tail suction outlet. The seed kernel discharging opening is connected with a top feeding opening of the multi-stage air separator through a seed kernel chute. An air separation discharging opening is formed in the bottom of the multi-stage air separator, and an air separation hull outlet is arranged on the right side of the top of the multi-stage air separator. The top suction outlet, the tail suction outlet and the air separation hull outlet are connected with a suction pipe. According to the kernel-hull separating system of sunflower seeds, un-hulled sunflower seeds, sunflower seed hulls and sunflower seed kernels can be separated, seed kernels including 16% hulls can enter the multi-separation air separator to continue to be subjected to air separation hulling, seed kernels discharged from the air separation discharging opening include 9% hulls or below, the quality of sunflower seed oil can be greatly improved, and economic benefits can be improved.

Description

technical field [0001] The invention relates to a kernel shell separation system for sunflower seeds, which is used for separating the peeled sunflower seeds from the husks, and belongs to the technical field of food processing equipment. Background technique [0002] Sunflower oil is golden in color, clear and transparent, and has a fragrant smell. It is an important edible oil. It contains a lot of essential unsaturated fatty acids such as linoleic acid, which can promote the regeneration and growth of human cells, protect skin health, and reduce the accumulation of cholesterol in the blood. It is a high-grade nutritional oil. [0003] The global production of sunflower oil generally shows a slow growth trend. From 2012 to 2015, the average annual compound growth rate of global sunflower oil production was 7.72%. In 2018, the global production of sunflower oil exceeded 17 million tons. Ukraine, Russia and the European Union are the main sunflower oil producing countries a...

AI Technical Summary

Problems solved by technology

Due to the poor separation effect of the kernel and the shell, the content of the shell and shell in the seed kernel entering the follow-up section is usually about 16%, which is not up to the ideal ratio. Because the shell contains a lot of wax, it affects the quality of sunflower oil. quality, which also seriously reduces the economic indicators of production and processing
