Description

Technical Field

[0001] The utility model relates to the technical field of yogurt production, in particular to a preheating treatment device for yogurt production. Background Art

[0002] Yogurt is a dairy product that is popular among consumers, and is mainly made from fresh milk. During the production process, the milk is first sterilized. This step is to kill harmful microorganisms that may exist in the milk and ensure the safety of the product. After sterilization, the milk needs to be preheated. The purpose of preheating is to optimize the temperature of the milk so that it reaches an environment suitable for the growth of lactic acid bacteria. Thereafter, active lactic acid bacteria are added to the milk for fermentation. These lactic acid bacteria reproduce in a suitable temperature and environment, convert lactose into lactic acid, and thus coagulate the milk to form yogurt. In the preheating process of the existing yogurt, it is not convenient to evenly heat the yogurt raw materials, and it is not convenient to accurately control the heating temperature, resulting in uneven heating of the raw materials in the tank body, and during the heating process, it is not convenient to fully stir the yogurt raw materials in the tank body, so that the yogurt raw materials contact the inner wall of the tank body unevenly, thereby reducing the heating efficiency of the yogurt raw materials.

[0003] For example, Chinese patent CN218303226U discloses a preheating treatment device for yogurt production, comprising a workbench, on which a heat treatment mechanism is installed, the heat treatment mechanism comprising a heating tank fixed on the workbench, the inner wall of the heating tank being a hollow structure, an insulating sleeve being arranged on the outer side of the heating tank, a first shell being fixed in the inner wall of the heating tank, an electric heating rod being installed inside the first shell, a first liquid port being installed on the side of the heating tank, a second liquid port being installed on the bottom of the heating tank, and a milk storage tank mechanism being installed inside the heat treatment mechanism.

[0004] The preheating treatment device for yogurt production has the following disadvantages: by arranging a heat treatment mechanism to heat the milk in the milk storage tank mechanism in a water-insulated heating manner, it can effectively avoid temperature runaway and excessive heating of the milk; however, since the water-insulated heating method transfers heat through water, its heating efficiency is usually lower than that of direct heating, resulting in a relatively slow entire heating process and relatively rough temperature control, resulting in uneven heating of the raw materials in the tank body; during the heating process, it is not convenient to fully stir the yogurt raw materials in the tank body, thereby reducing the heating efficiency of the yogurt raw materials.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In view of the problems in the related technology, the utility model proposes a preheating treatment device for yogurt production to overcome the above technical problems existing in the existing related technology.

[0007] To this end, the specific technical solutions adopted by the utility model are as follows:

[0008] A preheating treatment device for yogurt production comprises a workbench, a heating tank is inserted at the top of the workbench, a cover plate is arranged at the top of the heating tank, a servo motor is penetrated at the top of the cover plate, a rotating rod is connected to the output end of the servo motor, a plurality of stirring components are arranged on the circumferential outer wall of the rotating rod, a frame is arranged at the top of the workbench and located on the top of the servo motor, a preheating treatment component matched with the heating tank is arranged at the top of the frame, a feeding hole is opened on the cover plate, a temperature sensor is arranged on the inner wall of the heating tank, a discharge pipe is arranged at the bottom of the heating tank, and a control panel is arranged on one side of the workbench.

[0010] Furthermore, in order to evenly heat the outer wall of the heating tank under the action of the preheating treatment component, so that the yogurt raw materials in the heating tank can be evenly heated, the uneven heating can be avoided to affect the processing quality of the yogurt, thereby improving the heating efficiency of the preheating treatment device for yogurt production, and the applicability is wider.

Under the action of the stirring component, the yogurt raw materials in the heating tank can be diverted, and the length of the path of the yogurt raw materials through the stirring plate is increased, so that the yogurt raw materials in the heating tank are fully stirred. At the same time, under the action of the preheating treatment component, the outer wall of the heating tank can be evenly heated, so that the yogurt raw materials in the heating tank can be heated evenly, avoiding uneven heating to affect the processing quality of yogurt, thereby improving the heating efficiency of the preheating treatment device for yogurt production, and having a wider applicability.
