AI Technical Summary

Problems solved by technology

Ordinary food materials are more conducive to digestion and absorption after ultrafine pulverization. After ultrafine pulverization of feed materials, their utilization efficiency will also be improved. Similarly, ultrafine pulverization of fertilizers will also improve the absorption of plants. Foodstuffs, fertilizers, and feed materials are made into ultrafine powders and then used, which has obvious beneficial effects. However, due to the high processing cost of ultrafine powders, this application method is not yet fully economically feasible.

[0007] The traditional distillation method basically uses heating to vaporize the fraction, and then liquefies the gaseous fraction to realize the extraction of the gasifiable components in the material. The traditional distillation method is due to the slow gasification rate of the gasifiable components, and the gaseous The liquefaction of distillates requires additional energy and is not economical

[0008] To sum up, the existing process methods involving drying, ultrafine grinding, evaporative distillation, concentration, gasification and liquefaction, mixing, etc., because the moisture and heat exchange speed between the material and the working medium is not fast enough, the process is long and the operation is difficult. Due to factors such as high temperature, there are problems of high energy consumption, high processing cost, and difficult quality assurance, so that it is used to solve the problems of rapid normal temperature drying in the production of intermediate raw materials, ultrafine grinding of large-scale materials, and the scale of volatile components in materials. Common problems such as sexual preparation are not fully economically viable
