1.Negative Pressure Conveying 
Working principle:
The negative pressure conveyor forms a negative pressure air flow under the vacuum, under the action of this air flow, the material being conveyed is instantly conveyed to another container through the hose or pipe that sucks the material. Since the material is always under vacuum during the conveying process, even if there any accidental leakage happen, the material will not leak into the surrounding environment.

Features:
PLC automatic control, simple operation. Comply with GMP standards(Good Manufacturing Practice of Medical Products) and meet CIP requirements; Dust-free operation, conveying process environment friendly;Low maintenance costs;

2.Positive Pressure Conveying 
System introduction:
This system generally uses an air compressor as the air source, and the silo pump, high-pressure rotary valve, screw pump, etc. as the feeding device. The air and the material are fully mixed to make the material fluidized. it is suitable for material with long conveying distance, good fluidization, high abrasion, and mass transportation.  
Features:
1.Conveying capacity is large,no effect on the quality of the material
2. low air consumption
3. Automated control system 
4. Multi-point feeding and multi-point unloading

Remark:
-The sending tank/ silo is a pressure vessel, which is a mandatory equipment
-Air source is generally a screw air compressor, and the post-processing equipment must be matched
