Dilute phase pneumatic conveying
Dilute phase pneumatic conveying systems.
In DILUTE PHASE PNEUMATIC CONVEYING, under vacuum or positive pressure, the material is transported in suspension within the pipe and the particles are uniformly distributed over the entire cross section of the pipe (the flow is very homogeneous). The solids concentration is relatively low and the conveying velocity is relatively high.
One of the main advantages of this type of PNEUMATIC CONVEYOR, especially in the food industry, is that the pipe can be left clean after conveyance. The inside of the pipe is usually always empty so that different products can pass through it with a minimum risk of cross-contamination. A bag filter with an automatic cleaning system takes care of the air-product separation. The conveying air is usually generated by a turbine.
