Vibrating Sieve for Rapeseed

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.

Coarse sieve and fine sieve are required in the process of screening rapeseed. Impurities with large particle size of rapeseed such as leaves, rapeseed stems, etc. are used for the first impurity removal and cleaning, and then vibrating sieve removes the unfilled and shriveled seed raw materials, including Cleaning of fine sand, soil and other powder impurities in seed raw materials. The screening effect of Vibrating sieve on seeds has a great influence on the performance of seeds in the later stage. Let us explain in detail the two types of screening.

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

2. After the coarse screening 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. Seeds that have been finely screened generally have a higher emergence rate and later yield, and the finely screened seeds can also be weighed and packaged.

Thevibrating sieve for rapeseedeffectively improves the quality of rapeseed oil and is widely used in the rapeseed oil industry.
