The small soybean residue organic fertilizer dryer is a combination of water and oily materials, and water is not easy to handle. In response to this physical characteristic, a complete set of dehydration and drying equipment is used to reduce the water content to less than 12% at once. We use a production technology of DC vortex and AC reciprocating block multi loop dryer, which can fully utilize heat energy throughout the entire drying process, making the soybean residue evenly heated, The dried soybean residue has good color, minimal loss of nutrients, and low energy consumption. After dehydration, it enters the drying equipment and is evenly distributed in the drum under the flipping of the plate. It is evenly dispersed in the dryer and fully contacts with hot air, accelerating heat and mass transfer during drying.
The organic fertilizer dryer is divided into three parts: a heat source, a drying part, and a separation device. After the material enters the dryer, an induced draft fan is used to extract and pressure the dried material into a spiral device for separation to achieve the drying effect. After entering the separation device, the air flow and material are separated, and the air flow is discharged from the upper chimney, while the material is discharged from the lower end.
The working principle of a small soybean residue organic fertilizer dryer: After the dehydrated wet soybean residue enters the dryer, it is evenly distributed in the drum and flipped, and fully contacts with hot air in the dryer, accelerating heat and mass transfer during drying. During the drying process, the soybean residue is discharged from the other section of the drying machine through a star shaped discharge valve under the action of a slanted plate and a hot medium. The selection and design of the process parameters, equipment technical parameters, and structure of the soybean residue drying machine production line were obtained through careful analysis and research of the soybean residue materials, and verified through actual soybean residue drying experiments. In the design of the scheme, full consideration was given to the characteristics of high moisture content, high protein content, and high viscosity of soybean residue, and a series of unique and innovative technologies and processes were adopted to solve the problem, ensuring a good drying effect.
