Application of ultrafine grinding technology in agricultural product processing
Food powder plays an important role in people’s daily life and food processing. As powder is frequently used in food, in order to meet people’s various requirements when using food powder, it is necessary to understand the processing methods of powder. and various changes in processing properties, powder processing technology is continuously researched and developed by relevant researchers. Among the many types of food processing powder and raw material processing technologies, ultrafine grinding technology is an emerging agricultural product processing technology that can effectively prepare ultrafine powder. This technology can increase the utilization rate of processed materials and improve processing characteristics, Improve product quality and make it widely used in the food processing industry. By summarizing the working principle and usage characteristics of ultrafine grinding equipment technology, this paper focuses on the actual use of ultrafine grinding equipment technology in various fields, makes important prospects for the development prospects of ultrafine grinding technology, and summarizes the current applications of this technology. Problems that need to be solved urgently.
1. Fast crushing speed and good temperature controllability
There is basically no overheating during the entire process of ultrafine grinding technology, and it can also work at low temperatures. It is a low-temperature grinding technology. The micronization process lasts for a short time, and most of the biologically active chemical components will not be taken away by the process, which is conducive to the production of all necessary high-quality micronized products. Ultra-fine grinding technology can use medium, low or ultra-low temperature grinding according to the needs of different materials, so that the properties and processing requirements of the materials can achieve the desired results.
2.The particle size of the powder is small and evenly distributed, which improves the physical and chemical properties of the material and increases the reaction speed.
Since the external force used by ultra-fine grinding technology on the raw materials is very uniform, the resulting powder has a uniform particle size distribution. After various ultra-fine grinding processing technologies, the specific gravity and surface area of the material gradually increase. When various biological and chemical reactions are carried out, the contact area increases, and the dissolution rate, reaction rate, etc. are improved. Research has found that when oat fiber is ultrafinely pulverized and then added to wheat flour dough, the degree of ultrafine pulverization is directly proportional to the moisture content and elasticity of the dough. Ultra-fine grinding technology saves production time and improves production efficiency. Research shows that when crop straw is ultrafinely powdered, the physical and chemical properties are significantly changed, the structural components of plant fiber can be rationally utilized, and the absorption of plant fiber in the animal body is reduced.
3.Save processing raw materials and improve raw material utilization
Some fibrous materials are not suitable for conventional crushing methods. The formation of larger particles will cause a lot of waste of raw materials, and most production processes require intermediate processes to meet the requirements. Products produced by ultra-fine grinding technology can be directly used in the production process and are suitable for the use of rare and precious raw materials.
4.Reduce surrounding environmental pollution and improve the quality of processed materials
The entire ultrafine grinding process is carried out in a closed environment, which prevents external contamination during this process and does not cause pollution to the outside world. This technology is suitable for use in food and medical health products under high standard environmental requirements. Ultra-fine grinding technology is a physical processing process that will not be adulterated or mixed with other substances. Especially during the processing of Chinese herbal medicine, the naturalness will be guaranteed. Therefore, this technology ensures the naturalness and safety of the raw materials.
5. Improve the body’s digestion and absorption of nutrients.
According to research, after the ultra-finely pulverized material enters the digestive system, its particle size is very small, 10-25 μm or even below. The nutrients will not be released after a long and complicated pathway, and because the particles are smaller, they are more It is easily absorbed into the lining of the small intestine, thereby increasing the rate of nutrient excretion and giving raw materials more time to be absorbed and utilized.
