External air flow distribution pulsation fluidizing drying device

Abstract

The external airflow distributed pulsate fluidizing drying apparatus includes drying tank, fluidizing bed, material guiding device and airflow distributor, and features that under each of the fluidizing beds, there are increased 'funnel' tubes with passage cross section varying rate greatly reduced along the material shifting direction. The airflow distributor is outside the drying tank and includes transmission shaft, rotating disc and cylinder shell. The hot airflow performs the double actions of both drying and material transmission.

Description

technical field [0001] The invention provides an external air distribution pulsating fluidized drying equipment, which belongs to the technical field of mechanical equipment for dehydrating and drying agricultural products and chemical products. Background technique [0002] At present, the drying form of agricultural products commonly used in China is hot air convection drying, including fixed bed and ordinary fluidized bed. Among them, the fixed bed drying speed is relatively slow, while the ordinary fluidized bed is in order to make the material reach a fluidized state and ensure the drying speed. Channeling, local agglomeration and other phenomena. The hot air drying currently used is mostly open, which not only wastes energy, but also pollutes the environment and leads to poor working conditions. In short, the current hot air convection drying method has problems such as high energy consumption, many manual operations, and low production efficiency, and the market com...
