Description

Technical Field

[0001] The utility model relates to the technical field of milk powder production equipment, in particular to a powder sieving machine used for producing milk powder. Background Art

[0002] Milk powder is made from fresh milk, or fresh milk as the main raw material, with a certain amount of plant or animal protein, fat, vitamins, minerals and other ingredients added, and almost all the water in the milk is removed through sterilization, concentration, drying and other processes. After dilution with water, it can automatically disperse into a powdery solid form of an emulsion suspension. The purpose of milk powder processing is to reduce the moisture content, light weight, small volume, convenient storage and transportation; preserve nutrients to inhibit microbial growth and extend the storage period. The production of milk powder also requires a powder sieving machine to sieve milk powder of different particle sizes, and then obtain milk powder with finer powder particles to meet the production needs of milk powder. Therefore, powder sieving is an indispensable process in milk powder processing.

[0003] For example, Chinese patent announcement number: CN219210609U is a powder sifting machine for producing milk powder, comprising: a powder sifting machine body and a lower hopper welded on the top of the powder sifting machine body; a box door hinged on the front of the powder sifting machine body; an oscillating powder sifting mechanism arranged on the side of the inner cavity of the powder sifting machine body; and a milk powder containing mechanism movably installed at the bottom of the inner cavity of the powder sifting machine body, the top of the lower hopper is hinged with a dust cover, the inner cavity side of the powder sifting machine body is provided with a vibration groove, and the oscillating powder sifting mechanism includes a detachable powder sifting unit slidably connected to the side of the inner cavity of the powder sifting machine body. The utility model uses a two-stage oscillating powder screening mechanism to cooperate with sieves of different mesh sizes to screen milk powder, separate milk powder of different particle sizes according to demand, and then cooperates with the oscillation of the disassembling and assembling powder screening unit to make the milk powder quickly screened and separated, thereby saving labor costs when screening milk powder. However, the feeding mechanism of the powder screening machine is single, which easily leads the milk powder to be concentrated and accumulated on the powder screening net, making it inconvenient to evenly sprinkle the milk powder on the powder screening net, which is inconvenient to use. At the same time, it is inconvenient to discharge the large-particle milk powder screened out, which reduces the use efficiency of the powder screening machine. For this reason, we propose a powder screening machine for producing milk powder. Utility Model Content
