1. Distiller's grains are by-products in wine production, which have the characteristics of low price, large yield, rich nutrients, and good fattening effect. The development of distiller's grains into unconventional feed can greatly alleviate the shortage of feed resources, reduce breeding costs, and improve economic benefits. The complete set of equipment for the production line of distiller's dried grains has been put into use in many domestic beer enterprises and feed processing enterprises, and has created considerable economic benefits.

working principle
The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material moves to the other end of the inner layer and enters the middle layer for countercurrent drying. The material is continuously raised in the middle layer, showing two steps forward and one step backward. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in the outer drum in a rectangular multi-loop manner. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not achieve the drying effect is caused by Because of its own weight, the material cannot be moved quickly. The material is fully dried in this rectangular copy board, thus achieving the purpose of drying.

2. Liquor lees dryer is also known as multi-layer copy plate type rotary drum dryer. This machine is based on the advantages of ordinary single-layer or multi-layer drum dryers. It cannot be adapted to moisture greater than 60%. Adhesive and cohesive material drying and defects such as low evaporation capacity per unit area and high fuel consumption due to the "black hole" phenomenon in the center of the drum, optimize the internal structure design, strengthen the function of throwing and dispersing materials, and fill the "black hole" in the center of the drum "The surface area of the material is fully expanded, and the material is fully contacted with hot air to transfer heat and evaporate the moisture of the material. Because the material particles are relatively small, the heat transfer and evaporation speed of the moisture is greatly increased. The practice of large-area production has proved that the multi-layer plate type rotary drum dryer has a water evaporation capacity of 40-50kg water/m2·h per unit area than ordinary drum dryers, which is 2-3 times that of ordinary drum dryers. The capacity of the size dryer is increased by more than 50%, the fuel energy consumption is reduced by more than 30%, the equipment area is more than 40% smaller, the moisture of the dried material is more uniform, and the efficiency is increased by more than 40%. Suitable for drying 50-85% high humidity materials such as sludge, bean dregs, starch dregs, sauce dregs, sprayed corn husks, cassava dregs, beer lees, liquor lees, straw, pasture, organic fertilizer, chicken manure and other high humidity materials. The company can optimize the design of the drying process technology according to the characteristics of each biomass material, the output size, application requirements, cost control, automation level, and on-site working conditions.
working principle
The material flow is: 60-65% of the liquor lees screw conveyor is sent to the mixing drum dryer to achieve downstream drying. The materials are continuously picked up and scattered under the copy board and move forward in a spiral manner. Built-in multi-layer copy board structure Fully stir and disperse the material, the material and the hot air have full quality and heat exchange, and the moisture quickly evaporates and vaporizes. The material that achieves the drying effect quickly travels out of the drum under the action of the hot air. The wet material that does not achieve the drying effect cannot travel quickly due to its own weight. The drum is fully dried to achieve the drying effect and complete the drying process, which is discharged by the screw conveyor. A shock cleaning device is installed inside the drum to prevent the material from adhering to the wall of the drum.

The gas flow is: the air is pressurized by the hot blast stove blower into the hot blast stove for combustion and heating, and the temperature reaches 600-950 ℃. It is sucked into the dryer by the induced draft fan after the dryer to dry the material and evaporate the moisture. After three layers of heat exchange, the wind temperature The temperature is lowered to 55-60℃ and discharged out of the dryer. The dust-containing moisture is collected by the cyclone dust collector, and the wet dust collector is purified and discharged up to the standard.
