Description

Technical Field

[0001] The utility model relates to the technical field of whole milk powder processing, in particular to a screening device for whole milk powder production. Background Art

[0002] Whole milk powder is produced from pure milk, which basically maintains the original nutrients in milk, with protein not less than 24%, fat not less than 26%, and lactose not less than 37%. After dehydrating the whole milk powder, some of the whole milk powder will clump, so it is necessary to screen the whole milk powder to facilitate the subsequent canning of the whole milk powder.

[0003] According to the description of a screening device for milk powder production disclosed on the patent website (authorization announcement number: CN 216261827 U), "The utility model discloses a screening device for milk powder production, including a screening box, a discharge sleeve fixedly connected to the lower end of the screening box, the discharge sleeve is a conical structure, a rotating drum is rotatably connected in the screening box, a group of sieve holes are evenly opened on the side wall of the rotating drum, and a driving mechanism is arranged between the upper end of the side wall of the screening box and the rotating drum. The beneficial effect of the utility model is that the driving shaft of the driving mechanism rotates, and the driving bevel gear and the driven bevel gear are driven to drive the rotating drum to rotate at a high speed, so that the semi-finished milk powder in the rotating drum generates centrifugal force, and finally the sieve holes can be used to screen out the agglomerated milk powder, thereby improving the screening efficiency in the milk powder production process."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model drives the drum to rotate at high speed through the transmission of the active bevel gear and the driven bevel gear, so that the semi-finished milk powder generates centrifugal force, and finally the agglomerated milk powder is screened out by the sieve holes. However, during use, a large amount of residue is easily attached to the drum after long-term use. Since the drum cannot be replaced in time, it is easy to affect the subsequent screening work, reducing the practicality of the device. In addition, during the screening process, a lot of milk powder will remain on the inner wall of the screening box, so the comprehensive collection of milk powder cannot be guaranteed. Therefore, it is necessary to improve a screening device for whole milk powder production to solve the above problems. Utility Model Content
