Description
Technical Field
The invention relates to an electric soymilk machine taking a stone mill as a grinding part, belonging to the technical field of food processing appliances.
Background
With the improvement of the living standard of people, various household appliances widely enter families, including various food processing devices, products such as juice presses, soymilk machines and the like which appear earlier are mainly used for processing juice, soymilk and the like, and various wall-breaking crushers in recent years appear on the market, so that not only can slurry be manufactured, but also various beans, nuts and the like can be crushed, and the functions are more comprehensive. Among various household processed foods, soybean milk is the most popular traditional food, has the advantages of rich nutrition, good taste, easy manufacture, high quality, low price and the like, and is a daily drink for people in various areas of the country, so the soybean milk machine is always the most interesting appliance among various food processing appliances.
In the appliance for processing the soybean milk, the traditional stone mill has a special position, the traditional stone mill is used for grinding and preparing the soybean milk by virtue of an upper grinding disc and a lower grinding disc which are made of stone, the processed soybean milk is thick and fresh and cool in taste, has unique thick fragrance of the soybean milk, has no residue and is excellent in taste, the soybean milk ground by the stone mill widely exists in cities and rural areas until seventies and eighties of the last century, and the steel mill has replaced the stone mill.
When various household soymilk machines in the market at present are used for preparing soymilk, the soybeans are smashed by means of high-speed rotation of a cutter, then a filter screen is used for filtering, and the soymilk with large particles filtered is heated to become an edible beverage. In recent years, various crushing wall breaking machines are popular, and the improvement of the crushing wall breaking machines mainly comprises that the rotation speed of a cutter is higher, so that the crushing is finer, the filtering is not needed, all the nutrition components can be kept, the dried beans can be directly crushed, and the soybean milk can be processed without soaking. The common defects of various household soymilk machines and crushing wall-breaking machines in the process of manufacturing soymilk are that as the technology of crushing beans is adopted, no matter how fine the crushed particles are, the particles are still, the filtered slurry is a suspension, and the thick feeling is realized when the filtered slurry is heated for drinking. The traditional stone mill soybean milk is prepared by grinding the soaked soybean, extruding the soybean milk, filtering, and has no bean dregs, is a particle-free liquid, and is fresh liquid juice when drunk, and has no any particle feeling even if thick. As the modern soymilk machine, the crushing wall-breaking machine and the traditional stone mill processed soymilk are actually two different liquids in properties, one is suspension and the other is granule-free juice, the two liquids are greatly different in composition. In the suspension, the proteins contained in the soybeans are not separated from other soybean fibers and still remain in a granular state, so the soybean milk produced by a soybean milk machine and a crushing wall-breaking machine contains a large amount of insoluble substances and cannot be processed into soybean products of soybean proteins such as bean curd, jellied bean curd and the like in an extending manner; the liquid of stone-ground soybean milk is a liquid containing soluble soybean protein and other soluble nutrients, has no insoluble components, is separated from insoluble bean dregs, and can be solidified and molded when processed into various soybean products such as bean curd. The obvious difference in ingredients is reflected in that the traditional stone mill soybean milk is obviously better than the soybean milk made by a soybean milk machine and a crushing wall breaking machine in taste, which is obvious for people who drink the traditional soybean milk.
With the progress of society and the improvement of living standard of people, masses put forward higher demands on living quality. Only with soybean milk, people want to drink the traditional stone-ground soybean milk with rich nutrition and excellent taste, and also want to use the modern technology to make the soybean milk rapidly and simply in the home, thereby providing convenience for the family life, so the design and development of a new generation of soybean milk machine becomes a new subject for enterprises and technicians.
