Distillers grains are rich in crude protein and crude fat, rich in minerals, and high in heat energy. The dried vinasse is made into compound feed, which is an economical and effective method to increase the potency and make it better digested and absorbed. According to different feeding standards of livestock and poultry, adding trace elements and other additives can make different compound feeds.

The vinasse dryer is also known as the multi-layer copy plate type rotary drum dryer. This machine retains the advantages of ordinary single-layer or multi-layer drum dryers. It cannot be adapted to weak adhesion, moisture content greater than 60%. The drying of cohesive materials and the 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 is fully expanded, and the material is fully contacted with hot air to transfer heat and evaporate the moisture of the material. Because the particles of the material are minimized, the heat transfer and evaporation rate of the moisture is greatly increased.

Dingli company can optimize the drying process technology design according to the characteristics, output size, application requirements, cost control, degree of automation, and on-site working conditions of each biomass material.
