Background

The drum dryer (also called drum dryer, rotary dryer, etc.) is a contact type internal heating conduction type drying machine, and is widely applied to the fields of chemical industry, brewing, manufacturing, pharmacy, fertilizer, municipal sludge treatment, etc.

The working process of the roller dryer is as follows: the material liquid to be dried flows into a receiving tank of a roller dryer from a high-level tank, the material is thinly (membranous) attached to the surface of the roller by a film distribution device, a heating medium is introduced into the roller, the food industry adopts steam, the pressure is generally 0.2-6 MPa, the temperature is 110-160 ℃, the material is vaporized by the heat transfer of the roller wall in the rotation of the roller, the roller completes the processes of film distribution, vaporization, dehydration and the like in one rotation period, the dried material is scraped by a scraper, conveyed to a finished product storage tank by a screw, and finally crushed or directly packaged. The moisture evaporated during heat transfer may be introduced into a corresponding treatment apparatus through a closed cover depending on its nature to trap dust or discharge. Because the temperature of the roller is higher, a large amount of water in the material bin is evaporated to become more and more viscous, so that the material is stuck to the bottom of the material bin to cause a large amount of loss, and the common solution is to cool the material bin by adding a cold water jacket, but the method has higher cost and is more complex; in addition, the dipping method is not easy to control the thickness of the dipping material, so that the thickness of the dried flaky product is different, and the product properties are affected. There is an urgent need for a simpler, more practical and cost-effective feeding and circulating device to solve the above problems.
