1. Pretreatment This is the operation of preparing seed batches for basic cleaning. The equipment required for this operation is usually for a single crop. A It consists of a perforated steel plate with a concave structure that can remove corn kernels (seeds). The perforated steel allows the seeds to pass and retain the embryo core and its parts. B. It removes tightly fixed husks from grass seeds to facilitate the process of sowing and germination. This process is called a green shell ship. C. It can remove lawn and other appendages from oat and barley seeds, hindering the processing of seed batches. This process is called a bear market. D. It scratches the hard seed coat by increasing the exchange of water and oxygen in crops such as alfalfa, broad beans and rice to promote the germination process. This process is called scarring.

2. Basic cleaning The step of this seed treatment is to remove larger, smaller, lighter, and thicker adulterants from the seed batch. It is based on weight, size, and density, using cleaners and air screens. It separates seeds that are too small in size from coarse impurities, such as garbage, soil mats, etc. A. According to the density and size of the seeds, by screening different grid sizes and their vibrations. B. After pelleting, screening or pretreatment, there are a lot of inert substances in the seeds. It is the top screen of the seed cleaner with holes larger than the ideal seed size to remove inert substances larger than the seed size. This process is called gettering. It removes lighter inert substances and adulterants from crop seeds with the help of air pressure. This process is called suction.

3. Classify seed batches according to commercial use. The size, shape, density, and color are called grading. This operation is intended as a further improvement of the seed batch. Grading requires different types of separators to remove weeds and broken and undesirable seeds. The different types of classification equipment are as follows.

A. The broken seeds, weeds and other round crop seeds of the disc separator can be removed by the disc separator. It can separate impurities, especially broken seeds, other crop seeds and weed seeds, which are longer or shorter than crop seeds.

B. It has two types of grading systems, namely forward removal of impurities that exceed the required seed size. Wheat, rice reverse grading-remove impurities larger than the required seed size

C. The gravity separator utilizes the density between high-quality seeds and undesirable high-quality seeds. It uses the principle of flotation, that is, the seeds are layered on the deck according to the vibration density. It improves the germination rate of seed batches because it removes immature, broken, and undesirable seeds.

D. The difference in the roundness or shape of the seeds of the spiral separator is the use of spiral or dropper separators to remove contaminants.

E. It can remove seeds of different varieties, crops or weeds according to different degrees of seed color. The color separator improves genetic purity, seed health, and separates seeds damaged by weathering and moisture.

F. Surface texture separator removes inert substances according to the difference in surface texture, and removes rough texture weeds and other crop seeds from smooth crop seeds.
