Abstract

The pulsate fluidizing drying machine includes a drying box, a fluidizing bed, a gas flow distributor, and a transmission unit. It features the fluidizing bed with a vibration unit for suspending inside the box, the bed gradually lowered in the material moving direction and the end connected to the material discharging port; the gas flow distributor approaching to the lower part of the fluidizing bed and comprising a transmission shaft, blades on fixed onto the shaft and a baffling board driven with the transmission unit; the increased guide unit below the gas flow distributor and vibrating unit. The present invention operates on pulsate gas flow distributing technology, is favorable to the heat transfer and heat transfer, and has high drying speed, high heat transferring efficiency, low power consumption, less cavitation damage, channeling, etc and excellent operation performance.

Description

Technical field

[0001] The invention provides a pulsating fluidized dryer, which belongs to the technical field of mechanical equipment for dehydrating and drying agricultural 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. As far as the production process is concerned, the use of ordinary hot air convection to dry agricultural products is a typical labor-intensive industry. The entire production process has many manual operations and low production efficiency. In addition, most of the hot air drying currently used is open. After drying, the hot air with a temperature as high as 50°C is directly dischar...
