Abstract
Description
Technical Field
[0001] This utility model relates to the field of dairy processing equipment technology, specifically to a plate sterilization device for pasteurized milk production. Background Technology
[0002] Pasteurized milk has become an important category in the dairy market due to its characteristics of "low-temperature sterilization and preservation of nutrients". Its core processing relies on sterilization equipment, which requires heating the raw milk to 60-85℃ and maintaining it for a specific time to kill pathogenic bacteria and some spoilage bacteria, while avoiding high temperature damage to milk proteins, active enzymes and other nutrients. The current mainstream pasteurization equipment is based on plate heat exchangers.
[0003] Utility model patent CN218898173U discloses a plate-type pasteurizer, belonging to the field of pasteurizers. It includes a base plate, with a sterilization tank mounted on one side of the top of the base plate. The sterilization tank is hollow inside. A heat exchange control box is mounted on the other side of the top of the base plate. A pump body is mounted on the upper surface of the base plate, positioned between the sterilization tank and the heat exchange control box, with both ends of the pump body communicating with the interior of both the sterilization tank and the heat exchange control box. The sterilization tank has an opening at its top, and a cover plate is mounted on the rear side of the opening via a pin. The cover plate is adapted to the internal dimensions of the opening. A column is vertically mounted on the rear side of the top of the sterilization tank. A mounting plate is symmetrically arranged on the top of the column near the cover plate. A winding wheel is mounted above the column on the rear side of the tank top. By controlling the rotation of the winding wheel, a pull rope is pulled, thereby opening the cover plate. An internal mechanism ensures the stability of the pull rope, thus ensuring the stability of the open cover plate.
[0004] While the aforementioned technical solutions have their advantages, these sterilization tanks still have some shortcomings in use. For example, the cover is connected by a hinge and opened and closed by a motor. Firstly, the gaps in the hinge may affect the sealing effect. Secondly, when the motor drives the cover to open and close, the stirring shaft extends into the tank, preventing the cover from opening fully; the opening angle is less than 90°, which obstructs the feeding area and hinders the smooth addition of materials. Therefore, we propose a plate-type sterilization device for pasteurized milk production. Utility Model Content
