The uses of grape pomace after drying are as follows:

1. As feed additive: Dried grape pomace is rich in nutrients, such as amino acids, vitamins and minerals, etc., and can be added to feed in proportion to feed livestock such as cattle, sheep and pigs. This can not only increase the growth rate and yield of animals, but also reduce economic costs.

2. Make organic fertilizer: grape pomace and other parts of grape pomace can become very ideal natural fertilizer after processing. This fertilizer can increase the content of organic matter in the soil, enhance the water storage function of the soil, help improve soil quality and promote plant growth.

Other uses: Dried grape pomace can also be used to make biomass pellets, activated carbon, make vinegar, extract grape seed oil, etc.

Dingli pomace dryer is mainly composed of drum crushing dryer, combustion furnace, feeding screw, discharging screw, conveying pipeline, dust collector, air shutoff device, induced draft fan, control cabinet, etc. The pomace is directly fed into the drum crushing dryer by the feeding screw, and is repeatedly picked up and scattered by the lifting board on the inner wall of the drum. After being broken up by the high-temperature crushing device at the head of the dryer, the wet material quickly generates humidity and heat with the high- temperature air. Transfer to complete the heat and mass transfer process. Due to the inclination angle of the drum and the function of diverting air, the material moves slowly from the feeding end, and after drying, it is discharged by the discharge screw, and the tail gas is discharged into the atmosphere after being dedusted by the dust collector.
