The pomace dryer is mainly composed of a heat supply source, a feeder, a rotary drum, a discharge machine, an induced draft fan, a discharger and a power distribution cabinet; Under the flipping of the copying plate of the cloth, it is evenly dispersed in the dryer and fully contacted with the hot air, which accelerates the heat and mass transfer of drying. During the drying process, under the action of the inclined copy board and the heat medium, the pomace is discharged to the star-shaped discharge valve of the other section of the dryer to discharge the dried product. The selection and design of the process parameters of the production line and the technical parameters and structure of each equipment are obtained after careful analysis and research on the pomace materials, and are verified by the actual pomace drying test. In the design of the plan, the characteristics of high moisture content, high protein content and high viscosity of the pomace are fully considered, and a series of original and unique technologies and processes are adopted to solve the problem to ensure a good drying effect.
