Factory supply Brewery Yeast Drum Drying Equipment in Feed Industry Process

Introduction

Drum yeast dryer is divided into single dryer and double dryer, which can be used for drying a variety of slurries, especially suitable for recycling waste yeast in breweries, and dryers of different specifications. It can meet the needs of breweries with an annual output of 50,000 to 300,000 tons. The machine is also suitable for drying treatment in food, chemical, pharmaceutical and other industries.

The drum dryer is a continuous operation device that dries the liquid phase material or ribbon material attached to the outer wall of the cylinder by means of heat conduction through a rotating cylinder. The material liquid to be dried flows into the material receiving tank of the drum dryer from the upper tank. The drying drum is driven by the transmission device, and the material is formed by the filming device to form a material film on the wall of the drum. The cylinder is heated continuously, and the moisture of the material film is vaporized by the heat transfer from the cylinder wall, and the material is scraped off by a scraper, and then conveyed to the storage tank through a screw for packaging. It has high thermal efficiency and can be operated continuously, so it is widely used in the drying of liquid materials or strip-shaped materials, and is more suitable for paste-like and viscous materials.

Working principle of roller scraper dryer

Drying process: Let the liquid or muddy material form a film on the surface of the drum heated by steam or other heat carriers. The drum is dried in one revolution. The product is scraped off with a scraper, and the exposed surface of the drum comes into contact with the raw material again. And form a film to dry.
The drum scraper dryer uses a certain method to spread the liquid or pasty material on the drum (hollow metal cylinder) with a 0.1-1.5mm film. The drum can be heated with steam, hot water or thermal oil. When the drum rotates once, the material can be dried and scraped off the surface of the cylinder by a special scraper. The drum scraper dryer generally rotates at a speed of 4 to 6 rpm.
The drying of the paste-like material is to adjust the thickness of the material and to compact the material layer. On the side close to the feeding device, a material compression shaft is installed to make the material evenly spread on the drum. In order to make the material easier to fall off when the scraper discharges the material, before the scraping, the cold air pipe can also be used to blow a certain amount of cold air to cool the material.
