Description
Technical Field
The invention relates to the field of food machinery, in particular to jet impact grinding equipment and a jet impact grinding method for food full-component pulping.
Background
With the rapid development of society and economy, the living standard of people is continuously improved, the dietary habits of consumers are gradually changed from the prior color, aroma and taste shapes to the nutritional and health shapes, and the natural nutritional ingredients of the food are more and more emphasized. The full-ingredient food not only comprises food parts which are eaten by people in daily life, but also comprises parts which are usually discarded in the eating or processing process due to poor mouthfeel and other reasons, such as bean dregs generated in the preparation of bean products, bran generated in the fine processing of grains, fruit and vegetable skins generated in the processing process of fruit and vegetable beverages, and the like, and the food components usually contain rich natural nutrient substances, so that a large amount of nutrient substances are lost when the full-ingredient food is treated as a food byproduct or directly discarded, and the utilization rate of raw materials is seriously reduced. The full-ingredient food reserves all nutritional ingredients of the food, not only meets the requirements of consumers on food nutrition, but also can well solve the problems of nutrition loss, low raw material utilization rate and the like caused by byproducts in the food finishing process.
However, the whole component food contains a large amount of dietary fibers due to the edible skin of the food, the dietary fibers have high toughness, and part of the dietary fibers are insoluble in water, so that the whole component food is crushed only by using the conventional crushing equipment in the industry, such as a colloid mill, a homogenizer and the like, and a good crushing effect is difficult to achieve, so that the material particles are coarse, the mouthfeel is very poor, and the requirements of consumers cannot be met.
Compared with the common crushing equipment, the dynamic high-pressure micro-jet has better crushing effect, the material can reach the micron or submicron level, the crushing principle is that after the material is divided into a plurality of strands of thin flows in a specially designed micropore flow channel, most energy is released instantly to generate huge pressure drop after strong impact, and therefore the superfine effect on the material is achieved. A great deal of research is carried out on the aspect of dynamic high-pressure micro-jet in the earlier stage of the laboratory, and the dynamic micro-jet technology shows great advantages in the aspects of material ultrafine grinding, emulsification homogenization, auxiliary sterilization and food molecule physical modification, but because the diameter of a micro-pore flow channel of the dynamic high-pressure micro-jet equipment is very small (70 micrometers), the selection of materials is greatly limited in the application process, particularly when large-particle fiber materials such as bean skin, cereal bran, fruit and vegetable skin are treated, the blockage of the micro-pore flow channel is easily caused, the treatment capacity of the dynamic high-pressure micro-jet equipment is very small, the dynamic high-pressure micro-jet equipment is difficult to be used for large-scale production, and therefore, a grinding equipment which has excellent grinding effect and can be used for industrial production at the same time is urgently required to be developed so as to promote the development of the whole-component industry of food.
