How is the dryer applied to the processing of puffed feed?

Drying is one of the most important processes in the processing of expanded feed. Today's multi-layer circular vibrating dryers are being used in the processing of expanded feeds to replace traditional conveyor belts and chain-type box dryers. The following is a discussion of how multi-layer circular vibration dryers can be used in expanded feed processing.
1. Composition of the drying system The multi-layer circular vibration dryer is applied to the processing of puffed feed. The drying system consists of a multi-layer circular vibration dryer, a damper, a steam heat exchanger, a blower, an induced draft fan, and a cyclone. And a winder and other components. The technical key of the design of the drying system is firstly, the rational design of the structural principle of the multi-layer circular vibration dryer, and the second is the reasonable selection of the parameters of the drying wind network.
2. Basic structure and principle of the dryer The existing multi-layer circular vibration dryer generally has a feed port, a top cover, an exhaust gas outlet, a multi-layer drying bed, a hot air inlet, a discharge port, an excitation plate, and a vibration isolation spring. , excitation motor and frame. The multi-layer drying bed is composed of an inner and outer short cylinder, an annular horizontal sieve plate and a baffle plate. Each layer of annular horizontal sieve plate has a discharge opening, and when connecting the inner and outer cylinder flanges of each layer bed, the upper and lower discharge ports are staggered, so that the material of the upper layer outlet can fall into the next layer. The inlet of the material to be dried is discharged from the top layer to the lowest layer.
3. The structure of the dryer is improved. The multi-layer circular vibration dryer is designed to be different from the structure of the general single material drying application. There are many varieties of puffed feed, and the particle size varies greatly. Therefore, for the dryer, it is necessary to strengthen the drying ability of the equipment in the production of large particles, and to avoid excessive drying and blowing of small granular products. In addition, it is also necessary to avoid the residual doping and pollution of the equipment during product conversion, which affects the appearance quality of the product. In summary, the application of the multi-layer circular vibration dryer needs to solve such problems as the problem of yield matching and hot air fan distribution, residual problems in the machine, and the quality and uniformity of the large-sized puffed feed.
