Paddy Pre-cleaning Process

Paddy pre-cleaning process is to preliminarily remove the straw, rice head, hemp rope, clod and the other bigger impurities from the raw grain to guarantee the smooth working of the latter machines and equipment. It is the first course for the rice processing machine line.

Cylinder cleaning sieve is the equipment to clear the raw grain. It is used to remove the big matters like straw, big stone, scrip and etc.



Product Feature:

● Inner sieve and outer sieve are fixed separately, so it is easy to make the change.

● Feed opening adopts pivoting support, which makes the whole machine compact.

● Specialized sieve-surface cleaning device.

● Higher output, small power consumption, small land occupation, simple operation and maintenance and etc.

Cone cleaning sieve is responsible for the clearance of various big matters and light matters, i.e. dust, brick and stone, clod, straw, wood chip, and hemp rope to guarantee the quality of the raw grain and avoid machine failure or damage. It is widely used for the pre-cleaning in the grain processing factory. 

Product Feature:

● The sieve drum is conical, which rotate around the axis. Raw grain enters the sieve drum from the small feed opening, and then moves to the big opening depending to the gravity, during this process, the big matters flow to the impurities port, and the grains pass through the screen hole to discharge out of the machine.

● Grain flows down smoothly, and the effective square is bigger to avoid the impurities like wrapped grass, hemp rope and etc. No need to clear the drum.

● Steady technical performance and production performance.

● Dust suction pipe is equipped on the top of the machine. After connected with gas, it can avoid the dust spillover.

Vibrating cleaning sieve is suitable for the clearance of raw grain in the grain process factory. Different size of screen surface can support to clear the big and small light impurities from wheat, paddy, corn and etc. it has two layers of screen surface which guarantee the best clearance effect for the grain with more big sundries.

Product Feature:

● Novel screen structure and durable frame guarantee the strength of the machine and result of use.

● Tilt angle, amplitude, throwing angle of screen box can be adjusted according to the requirement.

● Rubber spring support and vibrating motor make the work stable and reliable.

● Sieve frame is strong and even.

● Compact structure and good tightness.

● Low noise, small power consumption.

● Vibrating motor is used for the drive; exciting force, vibrating direction and angel can be adjusted according to requirement.

Rotary flat cleaning sieve is the equipment with multiple trajectories which combines air and screen with the base of screen. It is used to clear the big, small, light impurities from the raw grain. It supports the variation of screen size according to the different materials, and it changes the vibrating range by adjusting rotary speed and weight resultant of eccentric block to achieve the best cleaning effect.

Product Feature:

● Compact structure, steady running performance and good cleaning effect.

● Low noise, small power consumption, and high output.

● Feeding flow rate of feeding tank is steady. The grain is evenly distributed in the screen-width direction. Screen movement has three trajectories which support the wide suitability of grain with different impurities contents.
