Description

Technical Field

[0001] This application relates to the technical field of milk powder pretreatment equipment, and particularly to a milk powder production pretreatment equipment. Background Art

[0002] Milk powder is a powdery product made from fresh milk as the main raw material, with or without added auxiliary materials, through processes such as sterilization, concentration, and drying. It can better preserve the characteristics and nutritional components of fresh milk. Since almost all the water in the milk is removed during production, microorganisms cannot grow, thus greatly extending the shelf life of the product, and significantly reducing the volume and mass of the product, making it convenient for transportation. The production of milk powder is not simply drying the water in the milk, but using scientific processes and processing equipment to not only maximize the preservation of the nutritional components and flavor of cow's milk, but also have good reconstitution properties. The production of milk powder requires preheating and sterilizing fresh cow's milk, and the suitable temperature range is 75 - 85 °C.

[0003] Existing preheating and sterilizing treatment equipment generally heats fresh cow's milk by means of water bath heating to achieve the effect of preheating and sterilizing treatment, and discharges the fresh cow's milk after this step. Inevitably, a part of the milk will adhere to the inner wall of the equipment. This part of the milk is prone to deterioration in a high-temperature environment and will contaminate the subsequent fresh cow's milk. It is necessary to clean and dry the inner wall of the equipment in time. However, the existing milk preheating and sterilizing treatment equipment lacks efficient measures for automatically cleaning and drying the inner wall, making it inconvenient to use. Therefore, in view of the above problems, a milk powder production pretreatment equipment is proposed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, this application provides a milk powder production pretreatment equipment, which overcomes the deficiencies of the prior art and aims to solve the problem that the existing milk preheating and sterilizing treatment equipment cannot be efficiently self-cleaned and dried.

[0005] To achieve the above object, this application provides the following technical solutions:

[0006] A milk powder production pretreatment equipment, including a constant temperature barrel and a control computer. The top of the constant temperature barrel is covered with a barrel cover. In the middle of the barrel cover, a stirring mechanism extending into the constant temperature barrel is fixedly arranged. Two symmetrically arranged rigid water pipes are hermetically arranged on the barrel cover. The bottom ends of the rigid water pipes extend into the constant temperature barrel and are hermetically connected with automatic rotating spray heads at the ends. The top ends of the rigid water pipes are hermetically connected with water supply hoses. The constant temperature barrel includes a heating inner barrel, and a heat preservation outer barrel is fixedly sleeved outside the heating inner barrel. A closed space is formed between the heating inner barrel and the heat preservation outer barrel and is filled with heat transfer oil. A plurality of groups of electric heating plates are fixedly arranged on the inner wall of the heat preservation outer barrel from top to bottom.

[0007] By adopting the above technical solution, the whole inner heating barrel can be uniformly heated with heat-conducting oil, so that the fresh milk therein is fully and uniformly heated. After the fresh milk is processed and discharged, the external water supply device will transport high-pressure water flow to the water supply hose, and the water flow sprays out from the automatic rotating spray head through the hard water pipe to wash the inner heating barrel and the stirring mechanism, cleaning the fresh milk attached to both of them. Moreover, the automatic rotating spray head will automatically rotate under the impact of the water flow to improve the cleaning effect. After the cleaning is completed, the electric heating plate works again to raise the overall temperature of the inner heating barrel, evaporating the moisture brought by the cleaning and ensuring that the inside of the barrel is clean and dry.

A sealing ring is fixedly filled in the gap between the front end of the temperature sensor and the heat-insulating layer.

[0013] By adopting the above technical solution, the temperature sensor can be installed in a sealed and isolated manner, effectively reducing the interference of the temperature of the heat-conducting oil on the monitoring of the temperature sensor, so that the temperature detected by the temperature sensor is the temperature of the fresh milk.

[0014] As a preferred technical solution of the present application, the temperature sensor and the control computer are electrically connected through a data transmission line respectively, and the electric heating plate and the control computer are electrically connected through a control line respectively.

[0015] By adopting the above technical solution, a complete circuit can be formed, that is, the temperature sensor transmits the temperature information to the control computer through the data transmission line, and the control computer can intelligently adjust the power of the electric heating plate according to the temperature information and the set heating requirement, so that the overall heating meets the preset requirement.

[0017] By adopting the above technical solution, the stirring motor can drive the stirring shaft to drive the stirring paddle to rotate, stirring the fresh milk to evenly distribute the heat, thereby making the temperature of the fresh milk at various locations in the heating barrel equal.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] Refer to Figures 1-3 , a pre-treatment device for milk powder production, including a constant temperature barrel 1 and a control computer 6. A barrel cover 2 is provided on the top of the constant temperature barrel 1. A stirring mechanism 3 extending into the constant temperature barrel 1 is fixedly arranged in the middle of the barrel cover 2. Two symmetrically arranged rigid water pipes 41 are hermetically arranged on the barrel cover 2. The bottom ends of the rigid water pipes 41 extend into the constant temperature barrel 1 and are hermetically connected with an automatic rotating spray head 4 at the ends. The automatic rotating spray head 4 is a prior art, and reference can be made to an automatic rotating spray head disclosed in the publication number CN204134099U, which will not be elaborated here. The top ends of the rigid water pipes 41 are hermetically connected with a water supply hose 42. After the fresh milk treatment is completed and discharged, an external water supply device will deliver high-pressure water flow to the water supply hose 42. The water flow passes through the rigid water pipe 41 and sprays out from the automatic rotating spray head 4 to wash the inner heating barrel 11 and the stirring mechanism 3, cleaning the fresh milk attached to both of them. Moreover, the automatic rotating spray head 4 will automatically rotate under the action of the water flow impact to improve the cleaning effect. In addition, the constant temperature barrel 1 includes an inner heating barrel 11. An outer heat preservation barrel 12 is fixedly sleeved outside the inner heating barrel 11.

By adopting the above technical solutions, the inner heating barrel 11 can be uniformly heated integrally with the heat-conducting oil 13, so that the fresh milk therein is fully and uniformly heated. In particular, after the cleaning is completed, the electric heating plate 14 works again to increase the overall temperature of the inner heating barrel 11, evaporating the moisture brought by the cleaning and ensuring that the inside of the barrel is clean and dry.

[0029] Refer toFigures 2-4 Two evaporation ports 21 are provided on the barrel cover 2. A closed cover plate 211 is rotatably provided at the position where the evaporation ports 21 are provided on the upper end surface of the barrel cover 2.

By adopting the above technical scheme, the temperature sensor 53 can monitor the temperature of the fresh milk at the current position, and multiple groups of temperature sensors 53 can cooperate to monitor more accurate temperature information.

[0031] Reference Figure 5 One end of the isolating installation tube 51 is tightly connected to the inner wall of the insulating outer barrel 12, and the side surface of the other end of the isolating installation tube 51 is tightly connected to the insulating outer barrel 12. A sealing ring 54 is fixedly filled in the gap between the front end of the temperature sensor 53 and the insulation layer 52. By adopting the above technical scheme, the temperature sensor 53 can be installed in a closed and isolated manner, which can effectively reduce the interference of the temperature of the heat transfer oil 13 on the monitoring of the temperature sensor 53, so that the temperature detected by the temperature sensor 53 is the temperature of the fresh milk.

[0032] Reference Figure 1 The temperature sensor 53 and the control computer 6 are electrically connected via a data transmission line 55, and the electric heating plate 14 and the control computer 6 are electrically connected via a control line 141, to form a complete circuit, that is, the temperature sensor 53 transmits the temperature information to the control computer 6 via the data transmission line 55, and the control computer 6 can intelligently adjust the power of the electric heating plate 14 according to the temperature information and the set heating requirements, so that the overall heating meets the preset requirements.

[0033] Reference Figure 2 The stirring mechanism 3 includes a stirring motor 31 fixedly arranged at the center of the upper end surface of the barrel cover 2. The output shaft of the stirring motor 31 extends into the constant temperature barrel 1 and is fixedly connected to a stirring shaft 32 at the end.

By adopting the above technical scheme, fresh milk can be injected into the heated inner barrel 11 through the material injection port 23, and additives required in the pretreatment process can be added to the heated inner barrel 11 through the material adding hopper 22.

[0035] Working principle: The heat released by the electric heating plate 14 can be absorbed by the heat-conducting oil 13, so that the temperature of the heat-conducting oil 13 as a whole is evenly increased, thereby realizing the uniform heating of the heating inner barrel 11 as a whole, so that the fresh milk therein is heated evenly; at the same time, the stirring motor 31 can drive the stirring shaft 32 to drive the stirring paddle 33 to rotate through its own work, stirring the fresh milk to make the heat evenly distributed, thereby making the temperature of the fresh milk at various places in the heating inner barrel 11 equal, so that the temperature sensor 53 in the temperature feedback mechanism 5 can accurately detect the current real temperature of the fresh milk as a whole, and feed back the temperature information to the control computer 6, and the control computer 6 can determine the actual temperature of the fresh milk according to the temperature information and the set heating requirement. The power of the electric heating plate 14 is adjusted so that the overall heating meets the preset requirements; when the fresh milk is processed and discharged, the external water supply equipment will deliver high-pressure water to the water supply hose 42, and the water will pass through the hard water pipe 41 and be sprayed out from the automatic rotating spray head 4 to rinse and heat the inner barrel 11 and the stirring mechanism 3, and clean the fresh milk attached to both. The automatic rotating spray head 4 will automatically rotate under the impact of the water flow to improve the cleaning effect. When the cleaning is completed, the electric heating plate 14 will work again to increase the overall temperature of the heated inner barrel 11, evaporate the moisture brought by the cleaning, and ensure that the barrel is clean and dry. At this time, the closed cover 211 is opened synchronously to discharge the water vapor generated by evaporation from the evaporation port 21.
