Manufacturing and processing method for infant milk powder

Abstract

The invention belongs to the technical field of milk powder production, and particularly relates to a manufacturing and processing method for infant milk powder. The processing method comprises the main steps that the first step, inspection and measurement acceptance of original milk are conducted; the second step, purification of the original milk is conducted, specifically, high-speed centrifugal separation and purification of micro impurities such as somatic cells, white blood cells, red blood cells, dust and microorganisms in the impurities are conducted; the third step, cooling and storage are conducted, specifically, purified raw milk is cooled to 2-6 DEG C for storage; the forth step, preheat homogenization for sterilization is conducted, specifically, fat, added ingredients and thelike in milk are crushed; the fifth step, condense is conducted, specifically, the milk is vaporized at the temperature of 70-90 DEG C under vacuum pressure of -0.08-0.0895Mpa, and then an ultrafiltration membrane module is used for membrane separation; and the sixth step, drying and packaging are conducted. According to the manufacturing and processing method for the infant milk powder, the ultrafiltration membrane module is used for separating a membrane to prepare a milk powder wet material; and then spreading equipment is used for evenly spreading the milk powder wet material in a dryingplate, and thus the drying efficiency of wet milk powder can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of milk powder production, in particular to an infant milk powder production and processing method. Background technique [0002] Milk powder is a powder made by removing water from milk, which is suitable for preservation. Milk powder is a brewed food made from fresh milk or goat milk, which is processed by freezing or heating to remove almost all the water in the milk, and adding appropriate amount of vitamins and minerals after drying. [0003] Some designs of milk powder production methods use vacuum evaporators to condense the milk into cakes, and then dry them to make powder; The thin milk film remilling and so on. But the best way to make milk powder is the spray method invented by American Passy in 1877. This method is to vacuum-concentrate the milk to 1 / 4 of its original volume to become concentrated milk, then spray it into a drying room with hot air in the form of mist, dehydrate it and make po...

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, it is necessary to evenly spread the wet milk powder on the drying plate before vacuum freeze-drying of milk powder. When spreading the milk powder, a certain thickness should be maintained to increase the effect of vacuum freeze-drying of milk powder. High adhesion, it is easy to block the paving equipment, resulting in the problem of decreased production efficiency, a kind of infant milk powder production and processing method proposed by the present invention
