Production process of donkey milk powder

Abstract

A production technology for donkey milk powder comprises: extracting fresh donkey milk, measuring the content of microbe, nitrite and nitrate in donkey milk; rapidly cooling detection qualified raw milk by a plate-type heat exchanger and putting in a milk storage pot for storing; performing crude filtration on raw milk, adding natural carotene and soluble dietary fiber into filtered donkey milk, performing Pasteur low-temperature disinfection on the prepared donkey milk; putting disinfected donkey milk in a filter for secondary filtering; performing preheating and homogenizing on donkey milk subjected to secondary filtering; putting homogenized donkey milk in an evaporator to perform reduced-pressure triple-effect concentration and putting in a drying column for drying to obtain donkey milk powder; and sending donkey milk powder into a cooling bed for cooling, then performing vibration screening, and finally sending to a vacuum loading system to package donkey milk powder. The production technology provided by the invention not only helps to improve the extraction degree of donkey milk powder, but also helps to reduce the production cost of donkey milk powder, and also furthest keeps the nutritional compositions in donkey milk.

Description

technical field [0001] The invention belongs to a production process of milk powder, in particular to a production process of donkey milk powder. Background technique [0002] Donkey milk is a natural dairy product with low fat, low cholesterol, high calcium, rich selenium, beauty and anti-aging. The fat content is slightly lower than milk, the cholesterol content is only 15% of milk, the vitamin C content is high, 4.75 times that of milk, and the amino acid content in donkey milk is complete, of which the essential amino acid content is high, accounting for 46.7% of the total protein. Much higher than the content of 42.2% of milk and 38.1% of human milk. In addition, the content of trace elements in donkey milk is sufficient, and the content of calcium is rich, especially the content of selenium is high, which is 5.2 times that of milk. Compared with the "Selenium Content Standard", it is a selenium-rich food, so donkey milk has many functions such as strengthening the bod...

Problems solved by technology

Since donkey milk needs to be stored in a low temperature environment, and the storage time of donkey milk is also short, it is necessary to make donkey milk into milk powder, which will save a longer time and be more convenient to carry and transport. In the existing donkey milk powder In production, only 1 kg of milk powder can be extracted from 10 to 11 kg of donkey milk, which is much higher than the standard that 1 kg of milk powder can be extracted from every 8 kg of milk. During the production of donkey milk powder, problems of milk pipe blockage and excessive microorganisms are often prone to occur , which not only leads to the low output rate of donkey milk powder, but also causes the lack and waste of nutrients in donkey milk powder, which greatly increases the production cost of donkey milk powder
