Introduction
Air-screener has 3-4 layers sieve, With a very wide range of sieves available, this machine is very versatile and can be used for seed cleaning of almost all crops.
The machines sift based on aerodynamics and the surface speed difference of seed and impurities, adjusting the seed of the air current. As impurities are light, they are sucked into the cyclone duster, while seed is heavy and is transferred into a vibrating screen. The vibrating screen has Three layers sieves with four outlet which eject large impurities, small impurities and seed respectively, The vibration screen used for separating seeds according different sizes.

Features
1.The machine works with 3 or 4 sieve levels, The sieve are cleaned on ball frames, with rubber balls.
2.The  rubber  ball  sifting  structure  complies  with  international  standards,  Sanli’s  patented  rubber  ball  is highly elastic, endures and long lasting.
3. The sieves are tightly fit in the machine by a clamp-locking system for quick changing of the sieves and thorough cleaning of the machine.
4.The volume of air is variable and adjusted from minimum to maximum by a controlling handle, assuring very accurate cleaning and sorting of seeds. The blower has a very stable and reproducible output.
5. Transparent inspection windows for easy inspection and clean out.
6. The machine has a very low noise level.
7. Very easy and thorough cleaning of the machine and no contamination risk.
8. No wooden frames on the sieves where seeds can hide.
9. With cyclone duster, Environmentally friendly model.

Working principle sketch

Working principle
Feed grain into inlet hopper after air sieving, and then under the vibration the grain jumping and flow to the multi-layer sieving trunk, following the grains well-proportioned enter to the upper layer sieve via the rubber curtain. Selected grains will fall into the next lower sieving panel after sieving, chaff and debris blocked by sieves and transfer to the outlet of large impurity. The selected grains will fall into the lower layers sieving panels, and will be graded into different levels of the different grain sizes by sieving in different sieving layers, that caused by the layers sieving panels have different mash size. Selected grains flow to the outlets of good grain, fill into bag hung on the bag holder. Cap of outlets can be used when shift bagging that means the cap can be close when you change the bag. It is the whole work flow for the separator.
Use different sieve to different process of different type of grains. The observing windows on the sieving trunk are for checking operation.

Aspiration Chamber(Wind Sieve)
Removing dust, straws, hey, husk and other light weight impurity out of the grain.
Handle and knobs adjusting the gap of channel (wide at top and narrow at bottom) to obtain optimum aspiration separating result. Removal of all the light weight impurity while fine seed falling down.
