Vibro Sifter For Rapeseed Sorting

Rapeseed, also known as Brassica seed, is a herbaceous cruciferous crop and one of the main oil crops and nectar crops in my country. Cultivation throughout the country, divided into two kinds of winter rape and spring rape. Its planting area accounts for more than 40% of the country's total oil crop area, and its output accounts for more than 30% of the country's total oil crop output, ranking first in the world.

The fruit of rapeseed is silique, and the silique is composed of three parts: fruit peck, fruit body, and fruit stalk. After the silique is mature, due to the dehydration and shrinkage of the fruit petals, it can automatically crack, and the seeds are spherical or oval, and consist of three parts: the seed coat, the embryo and the remains of the endosperm. The chemical composition of seeds generally contains 3.9%-5.2% nitrogen, 24.6%-32.4% protein, 5.7%-9.6% cellulose, 4.1%-5.3% ash, and 37.5%-46.3% oil.

Rapeseed contains a certain amount of erucic acid, which will affect the quality of rapeseed and rapeseed oil. Rapeseed also contains a certain amount of sinapine, tannin and other chemical substances, all of which have certain toxicity, so the rapeseed cake needs to be detoxified before it can be used as feed.

The sieving effect of Vibro sifter For rapeseed sorting has a great influence on the performance of later seeds. Let us explain in detail the two types of sieving.

1. Coarse screening process

The seeds before the coarse sieving contain many impurities, and there are some impurities with larger particles, such as stones, hemp flakes, straw, plastic flakes, etc. In the process of coarse screening, the Vibro sifter screen is mainly used to remove impurities for the first time on the seed material.

2. After the coarse sieving process

Screen some fine impurities in the seeds. This process is relatively fine and requires a larger mesh screen to make the sieved seeds cleaner. The seeds after fine sieving generally have a higher emergence rate and later yield, and the fine sieved seeds can also be weighed and packaged. .
