Bean Processing Plant Positive Pressure Components

Bean processing plant positive pressure transmission is also called pneumatic pressure transmission, which is one of the pneumatic transmission forms. Positive pressure transmission consists of one system, which includes the following several devices:
 

The first positive pressure component of bean processing plant: roots blower. Roots blower is the power source of the system. It can press the outside air into the pipeline continuously. It forms high speed airflow in the pipeline, and depends on the airflow function to drive corn material advancing in the pipeline.
 

The second positive pressure of bean processing plant: airlock. It is the throat part of the system. It can convey corn material into the delivery pipe evenly and prevent the positive pressure air overflow from the pipeline.
 

The third positive pressure of bean processing plant: feed delivery pipe. It is the road for airflow and raw material movement. Its diameter should meet the requirement of conveying quantity and ensure the pipeline’s good sealing. It also requires the inner wall smoothness, less lines turning and large turning circle so as to reduce the motion resistance of the airflow and material in the pipeline.
 

The fourth positive pressure of bean processing plant: double-switch. When the conveying system has two or more emptying points, we need set double-switch or more switches in the pipeline.
 

The fifth positive pressure of bean processing plant: discharging device. The material of the positive pressure delivery system can be sent to the bin directly. Usually, we don’t need to set the special discharging device. The bin can be used as the discharging device in material and air separation.
 

The sixth positive pressure of bean processing plant: dedusting device. Tail gas treatment is one necessary part in positive pressure delivery system. The tail gas treatment refers to the treatment of the air discharged from the feeding process and the air separated from the material. The tail gas treatment has two forms: the one form is that several dedusting aspiration systems and bins use one set of dedusting device to process the tail gas. The another form is the unique aspiration system, which means that each bin has one small dedusting device with air blower. The dedusting work and the flour bin feeding process is synchronized.
