Oilseeds cleaning

Oilseeds cleaning sieve is mainly primary cleaning the impurity, is important in oilseeds pretreatment process.

Methods of Removing Impurity in Oilseeds

• Make use of the different sizes of impurities and oilseeds to separate them.
• Separate oil seeds and impurities by comparing the specific gravity between them.
• Make use of the difference of oil seeds and impurities in kinetic properties to separate them.
• Making use of the difference in the mechanical strength of oil seeds and impurities to separate them, like grinding, impact, and water solubility.
• Magnetic separation. Make use of the difference of oil seeds and impurities in magnetic properties to separate them.

Oilseeds sieve cleaning machine

The screening separation mainly makes use of the different sizes between oilseeds and impurities. With the aid of the relative motion of the mixed oil seed and the sieve surface, impurities of bigger or smaller size than oilseeds are sieved out. Oilseeds screening equipment for edible oil plants mainly includes slide sieves, vibrating screens, rotary flat sieves, and rotary screens. The vibrating screen is also called a flat screen, its screen surface can do the reciprocating movement. It can be used to clean up impurities in all kinds of oilseed. Featured with high cleaning efficiency and stable performance, the vibrating screen is widely used in the cooking oil mill plant.

Magnetic Separator

Magnetic separator is specially designed to remove magnetic metal impurities in oilseed. A permanent magnet or electromagnet is installed in the previous process of shelling machine, crusher, and flaking machine. Magnetic separation equipment includes magnetic steel, permanent magnetic cylinder, permanent magnetic roller, electromagnetic roller, and so on.

Specific-gravity destoner

The specific-gravity destoner is applied to separate oil seeds and stone by the difference of density and suspension speed between them. 1. Suction-type specific gravity destoner It is composed of a feeding mechanism, sieve body, vibration mechanism, suction mechanism, and frame. 2. Blower-type specific gravity destoner Blower-type destoner has the same working principle as suction-type destoner. The main difference between suction-type and blower-type is that there is a fan at the bottom of the blower-type destoner and don’t need to match a fan or wind net. But the blowing type will form positive pressure in the machine chamber, resulting in the leakage of dust air, which is not good for the working environment.

Cleaning Process characteristics:

1, The process is designed according to the character of the oilseeds, targeted, and will be more thorough clean for clean oilseeds;

2, To reduce the wear and tear for the follow-up equipment, reduce the dust at workshop;

3, To pay attention to energy saving and environment protection, reduce emissions, cost savings.
