The suspension type dryer
Technical field
The utility model relates to powder look unfamiliar product process equipment, especially dryer.
Background technology
Along with the raising of people's living standard, people are also more and more higher to the requirement of powder pastries, and not only the quality of powder pastries more and more is subjected to people's attention, and become first key factor that people choose the powder pastries.Powder is looked unfamiliar and is provided with this procedure of oven dry in the production. art, can be the middle redundant moisture oven dry of shaping powder face, make powder face typing and help storing, and the quality of baking operation directly has influence on the final product quality of powder face.In the prior art, the drying unit of powder face is generally the powder face box that loads the powder face and does level and come and go operation and come out until powder face drying and dewatering, powder face box is connected on the chain, the roller of chain cooperates with guide rail, powder face box is carried along guide rail, in course of conveying, powder face in the powder face box is heated, under the environment of high temperature and the roller of chain and guide rail directly roll continuously and contact, the roller and the rail friction of long-time chain, wearing and tearing will appear, that part of metallic dust that is worn still exists in the drying unit, by the hot air circulation in the drying course, the powder face of drying is undoubtedly a kind of pollution sources, on the powder face even stain can occur, directly influenced the quality of product when serious.And powder face box level comes and goes the method for operation of operation, because the stack and alternately layer by layer of powder face box, seriously increase the resistance of hot air circulation wind in the drying course and reduced the penetration power of wind, need to strengthen power of fan and air pressure air flow can satisfy, the energy consumption height, increase manufacturer's production cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of suspension type dryer, and is low, effective to drying efficiency height, the energy consumption of powder face, and pollution-free to the powder face.
