2. Specific gravity concentrator (seed concentrator): It is the equipment selected and processed according to the principle of seed density. There are two forms, one is negative pressure and the other is positive pressure. Negative pressure type is mostly used as a mobile single machine, and positive pressure type is mainly used in seed processing production line. The positive pressure gravity separator has large table top, long separation path and better separation effect. Remove the grains that are moth-eaten, moldy, rotten, shriveled and less dense than good seeds.
3. Pocket drum cleaner: It is the only cleaning equipment that sorts seeds by length, and can separate long and short impurities from seeds. There are single cylinder, double cylinder and multi-cylinder combination models.
4. Seed classifier: According to the use requirements of precision seeder, seeds are divided into several grades, mainly including cylinder classifier and vibration classifier.
5. Compound cleaner: refers to the combination of three or more combined operations such as air separation, screening, pit selection or stone removal.
6. Compound cleaning machine: refers to a machine that integrates cleaning functions such as air separation, screening and specific gravity separation, and has multiple functions. All the processing links such as air separation, screening and specific gravity separation are realized by feeding raw materials at one time, which reduces the lifting times, effectively reduces the crushing rate and reduces the labor force.
Seven, seed coating machine: refers to the seed coating agent coated on the surface of seeds, chemical treatment of seeds, from the mixing mode, can be divided into spiral mixing and drum mixing; From the way of liquid medicine atomization, it can be divided into three types: gas atomization, high-pressure liquid medicine atomization and disk-throwing atomization.
Eight, complete sets of seed processing equipment: refers to the factory equipment that can complete all the requirements of seed processing and its supporting equipment and accessories. According to the different processing objects, the complete set of seed processing equipment can choose a variety of processes and modes, such as dryer, air screen cleaner, pit drum cleaner, specific gravity cleaner, classifier, coating machine, weighing scale and so on. Supporting equipment includes conveying system, air network system, dust removal system, storage system, electrical control system, etc.
