At present, the common problem encountered in the drying equipment for alcoholic beverages is the high cost of drying. Shenyang Yitong Venture Technology Co., Ltd. has developed a process and equipment suitable for the drying of alcoholic slag, including coal consumption, electricity consumption, labor, etc., through the engineering practice experience in drying high-watery slag materials such as distiller's grains. Drying costs only 150 yuan. The device is currently used by dozens of customers.
According to the requirements of the state of dryness, yield, and use of alcohol waste, when the drying program is proposed, it is fully considered that for drying a large amount of high-humidity materials of alcoholic grains, a high-temperature direct-fire rapid drying process should be adopted, which can reduce energy consumption. , improve the drying efficiency, but also reduce equipment investment. And to avoid the alcohol grains in the dry state at high temperatures for a long time, the protein content may be reduced, affecting the quality of the material.
Because high-temperature flue gas is used as a heat source for drying, how to reduce the pollution of the flue gas to the material has become a key consideration in the selection and design of drying equipment. Generally, the pollution of the flue gas to the materials can be reduced from two aspects. Firstly, in the design of the hot blast stove, it is necessary to consider increasing the dust reduction treatment. In addition, the selection of the drying equipment and the design of the drying process are to reduce the material drying time as much as possible. Use high temperature rapid drying process.
The heat source is selected from direct fire hot air oven drying, which can not only obtain a higher drying air temperature, improve the drying efficiency, but also can significantly reduce the investment in equipment and ensure the product quality. This is because the material has a short residence time in the machine, the drying time is short, and the amount of water evaporation on the surface of the material is large. From the perspective of engineering practice, direct fire drying has basically no pollution on the lees.
Drying equipment mainly uses multi-layer rotary dryer, which is very suitable for rapid drying at high temperature. This kind of drying equipment is very beneficial to ensure nutrients in the material, protein and other nutrients are not lost, and the drying speed is fast. Especially when dealing with high output, high humidity and high viscosity materials, the advantages are very obvious.
Therefore, alcohol must use high-temperature rapid drying process. Taking into account the state of the material, considering the comprehensive cost of drying, a multi-layer rotary dryer should be used to dry it with high temperature and direct fire.
