The dregs feed dryer is highly adaptable and can dry high-humidity wastes including sauce residues, soy sauce residues, sesame oil residues, vinegar residues, etc. The unit uses coal (natural gas, gas) as energy and hot air as the drying medium. The process of using strong hot air to dry all kinds of wet materials at a high temperature with a difference in thermal moments. The main engine transmission device adopts electromagnetic speed regulation and is equipped with an automatic temperature control device. The color of the dried product after drying does not change and the original The color, taste and nutritional content of the material. The vinegar residue dryer uses coal (natural gas, coal gas, biomass energy, steam) as energy, hot air as the drying medium, and the use of strong hot air to dry all kinds of wet materials at a high temperature with instantaneous temperature difference. The main engine drives The device adopts electric control stepless speed regulation, and is equipped with an automatic temperature control device. After drying, the color of the finished product does not change, and the color, flavor and nutritional ingredients of the original material are retained.
