Selling and supplying second-hand drum dryers and dryers

Drum dryer is widely used in chemical, brewing, manufacturing, pharmaceuticals, fertilizers, urban sludge treatment and other fields.

Drum drumdryer(also known as rotary drum dryer, rotary dryer, etc.) is a contact type internal heating conduction type drying machinery. During the drying process, heat is transferred from the inner wall of the drum to its outer wall, passing through the food material attached to the outer wall of the drum and evaporating the moisture on the material. It is a continuous drying production machinery.

​

The drum of the drum dryer is a slightly inclined and rotatable cylindrical body, with wet materials entering from the upper part of one end and dry materials collected from the lower part of the other end. Hot air enters from the feeding or discharging end and is discharged from the upper part of the other end. The cylinder is equipped with a forward copying plate, which continuously picks up and sprinkles the material during the rotation of the cylinder, allowing it to fully contact with the hot air flow to improve drying efficiency and move the material forward. The heat source for drying materials is generally hot air, high-temperature flue gas, water vapor, etc.

The working process of a drum dryer is as follows: the liquid that needs to be dried flows into the receiving tank of the drum dryer from a high-level tank, and the material is thinly (in the form of a film) attached to the surface of the drum by a film distribution device. The drum is supplied with a heating medium, and steam is commonly used in the food industry, with a pressure generally between 0.2~6MPa and a temperature between 120~150 ℃. The material is vaporized by heat transfer through a simple wall during the rotation of the drum, and the roller completes the processes of film distribution, vaporization, dehydration, etc. in one rotation cycle. The dried material is scraped off by a scraper, transported by a screw to the finished product storage tank, and then crushed or directly packaged. The water evaporated during heat transfer can be introduced into the corresponding treatment device for dust capture or emission through a sealed cover depending on its properties.
