[0044] The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following embodiments do not represent all implementation methods consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application.

[0045] To solve the problem of poor sterilization effect in the production process of goat milk powder, see Figure 1-Figure 2The embodiment of the present application provides a sterilization system in the production process of goat milk powder, including: a first sterilization component, a second sterilization component 2, a third sterilization component and a control module.

[0046] The first sterilization component, the second sterilization component 2, and the third sterilization component are all in communication connection with the control module.

[0047] It should be understood that the control module is used for production process control and monitoring management.

[0048] The first sterilization component includes a pasteurizer and a first extended insulation pipe; the first milk silo is connected to the balance cylinder of the pasteurizer through a milk pump; the milk purifier of the pasteurizer is connected to one end of the first extended insulation pipe; the other end of the first extended insulation pipe is connected to the second milk silo.

[0049] It should be understood that the pasteurizer is a sterilizing device for liquid food. By utilizing the sensitivity of pathogens to temperature, most bacteria are killed by appropriate temperature and insulation time, while retaining some bacteria that are beneficial to the human body. This method not only effectively extends the shelf life of food, but also maintains the nutritional value and flavor of food. The pasteurizer used in this application is a four-stage pasteurizer. The first milk warehouse is used to store the goat milk that has just been collected, and the second milk warehouse is used to store the goat milk that has been purified and sterilized. The capacity of the first milk warehouse and the second milk warehouse can be selected to be 50 tons.

[0050] The goat milk in the second milk silo is transported by a pump and then heat-exchanged by a heat exchanger before entering the batching tank, and then measured by a scale at the bottom of the batching tank. When the required amount of milk is reached, the feeding into the batching tank is stopped, and the pre-measured goat milk, oil, water, nutrients, semi-fluid sugars and other ingredients are put into the vacuum mixing tank in proportion through pipelines for mixing. Finally, the batched milk is filtered and stored in the middle storage tank for feeding the triple-effect evaporator through a pump. There can be three middle storage tanks, and the volume of each middle storage tank can be 10,000 liters.

[0051] In some embodiments, when the bacterial counts of both goat milk and ingredients exceed the standard, in order to ensure the quality of the final product, an ultra-pasteurizer is connected in parallel before the intermediate storage tank. The ultra-pasteurizer adopts ultra-high temperature instantaneous sterilization technology, and can sterilize the ingredient milk again under special circumstances. The sterilization temperature can be selected to be 105-115°C.

[0052] The second sterilization component 2 is located inside the triple-effect evaporator, and the second sterilization component 2 is connected between the first-effect evaporator 1 and the flash tank 3; the output port of the triple-effect evaporator is connected to the concentrated milk tank, the dry powder machine and the third sterilization component in sequence through a pipeline.

[0053] It should be understood that the triple-effect evaporator is an efficient and energy-saving evaporation and concentration equipment, which realizes multi-stage evaporation by connecting three interconnected evaporators in series. In the first-effect evaporator 1, fresh steam is used to heat the material to boiling, and the secondary steam generated is used as the heat source of the second-effect evaporator, and so on, until the triple-effect evaporator. The working pressure and boiling point of each effect evaporator 1 are successively reduced, so that the secondary steam of the previous effect evaporator 1 can be used as a heating medium in the next effect evaporator 1, thereby realizing the cascade utilization of energy. The dry powder machine is a product used to convert liquid milk into powder after spray drying.

[0054] The second sterilization assembly 2 includes a second extended insulation tube and a sterilizer; one end of the sterilizer is connected to one end of the second extended insulation tube, and the other end of the second extended insulation tube is connected to the top of the flash tank 3.

[0055] It should be understood that the first extended insulation tube and the second extended insulation tube are used to keep the milk at a preset temperature within a preset time. The preset time is determined according to the type of milk, the length and diameter of the extended tube and the preset temperature. The preset temperature is determined according to factors such as the sterilization effect or the critical limit in the concentration. Specifically, the first extended insulation tube can keep the goat milk at 75-85°C within 15 seconds; the second extended insulation tube can keep the ingredient milk at 95°C within 25 seconds. Since the length of the insulation tube affects the sterilization effect, this application chooses to use an extended insulation tube. For example, the standard length of a conventional insulation tube is usually 12 meters, and this application can use an extended insulation tube with a length of 18 meters. The size of the second extended insulation tube is also related to the size of the triple-effect evaporator. For example, for the triple-effect evaporator with an evaporation capacity of 7 tons, the second extended insulation tube can be a steel pipe with an outer diameter of 89 mm and a wall thickness of 4 mm.

[0056] In some embodiments, the sterilizer includes a horizontal sterilization cylinder, one side of which is respectively connected to a liquid inlet pipe and a steam inlet pipe, and the other side of which is respectively connected to a liquid outlet pipe and a steam outlet pipe, a horizontal stirring mechanism and a power assembly are provided in the sterilization cylinder, the sterilization tube is respectively connected to the liquid inlet pipe and the liquid outlet pipe, and the stirring mechanism and the power assembly are connected to quickly and fully sterilize the ingredient milk.

[0057] In some embodiments, the control module is a distributed structure, including decentralized lower-level control and operation stations and centralized upper-level monitoring and management systems, and a process field bus communication method is used to build a network; the host computer can complete the automatic control of the entire production process according to the production tasks and specific recipes, and at the same time realize the collection, display, and alarm of various process parameters. The control system consists of a host computer for monitoring in the central control room, a centralized control programmable logic controller, and a field operation station.

[0058] The bus control method can turn various scattered devices into network nodes, and the bus allows various scattered devices to exchange information and jointly complete self-control tasks; this method can hang dozens of substations through a communication cable, and each substation can build a network according to local conditions and local materials; this method can save a lot of cables, cable troughs, connectors, etc. compared to traditional methods, and also makes all connections simple, greatly reducing the workload of system design, installation, and maintenance.

[0059] In some embodiments, the third sterilization component includes a first raw material sterilization feeding line and a second raw material sterilization feeding line;

[0060] The first raw material sterilization feeding line includes a first raw material sterilizer and a first feeding station; the outlet of the dry powder machine passes through the vibrating screen and the inlet of the first raw material sterilizer in sequence, the outlet of the first raw material sterilizer is connected to the inlet of the first feeding station, and the vibrating screen is located above the inlet of the first raw material sterilizer.

[0061] It should be understood that the milk powder output from the dry powder machine is filtered by the vibrating screen and then enters the first raw material sterilizer for sterilization, and the sterilized milk powder is finally transported to the powder bin above the packaging machine through the first feeding station. The first raw material sterilization feeding line is used to directly sterilize, feed, screen and package the milk powder.

[0062] The second raw material sterilization feeding line includes a second raw material sterilizer and a second feeding station; the inlet of the second feeding station is connected to the outlet of the second raw material sterilizer, and the outlet of the second feeding station is connected to the packaging machine.

[0063] The second raw material sterilization feeding line is used to sterilize packaging bags.

[0064] In some embodiments, both the first raw material sterilizer and the second raw material sterilizer are closed raw material sterilizers;

[0065] The closed raw material sterilizer includes a display 4, a stainless steel body 5, a sterilization lamp and a cleaning component; the cleaning component and the sterilization lamp are both arranged inside the closed raw material sterilizer, and the display 4 is arranged outside the stainless steel body 5; the display 4 and the cleaning component are both communicatively connected to the control module.

[0066] The closed raw material sterilizer can reduce dead angles, thereby improving the sterilization effect; the display 4 is used to display the working status and parameters of the closed raw material sterilizer in real time. Through the display 4, the operator can intuitively understand the operation of the equipment and adjust the parameters in time to ensure the sterilization effect. The cleaning component can effectively remove dirt and residues inside the equipment.

[0067] In some embodiments, the stainless steel body 5 is made of 304 stainless steel, the inner surface of the stainless steel body 5 is a mirror, the sterilization lamp tube is arranged in a fan-shaped groove of the stainless steel body 5, and the fan-shaped groove is located at the top of the inner cavity of the stainless steel body 5; the control module is communicatively connected with the sterilization lamp tube; the control module is configured to: adjust the intensity and exposure time of the sterilization rays emitted by the sterilization lamp tube.

[0068] The body of 304 stainless steel has good corrosion resistance and toughness. It can not only withstand the high temperature and high pressure environment generated during the sterilization process, but also meet food grade standards to ensure the hygiene and safety of the equipment. The internal surfaces of the closed raw material sterilizer are all mirrored, which not only helps to reduce the adhesion of dirt and residues and facilitates cleaning and maintenance; it also helps to reflect sterilization rays to improve sterilization efficiency and reduce the hiding space of bacteria and microorganisms. Providing a fan-shaped groove at the top of the inner cavity of the stainless steel body 5 not only helps to fix the position of the sterilization lamp tube and ensure that it can evenly irradiate the material to be processed, but also helps to prevent the sterilization lamp tube from being subjected to external impact or damage. Controlling the closed raw material sterilizer through the control module can achieve precise control and management of the sterilization process.

[0069] In some embodiments, the cleaning components in the second raw material sterilization feeding line include an industrial vacuum cleaner and an air shower device; the exhaust pipe of the industrial vacuum cleaner is connected to the exhaust system 6, and the industrial vacuum cleaner and the air shower device are both communicatively connected to the control device; the control device is also configured to: control the industrial vacuum cleaner and the air shower device to clean the floating dust on the surface of the packaging bag.

[0070] It should be understood that the industrial vacuum cleaner can effectively remove dust and tiny particles attached to the packaging bag through strong suction, thereby maintaining the cleanliness and hygiene of the production environment. The air shower device uses high-speed airflow to wash the surface of the packaging bag to remove residual floating dust and dirt.

[0071] The cleaning assembly is used in conjunction with an industrial vacuum cleaner and an air shower device to ensure thorough cleaning of the surface of the packaging bag. The operation of the two devices can be remotely controlled by the control device, thereby improving the automation of the equipment, reducing manual intervention, and also improving production efficiency and safety.

[0072] In some embodiments, the cleaning assembly in the first raw material sterilization feeding line includes an air filling device and a pressure sensor, and the outlet of the first raw material sterilizer is connected to the exhaust system 6; the air filling device and the pressure sensor are both connected to the control device in communication; the control device is further configured as follows:

[0073] When production stops, the ball valve at the outlet of the first raw material sterilizer is controlled to close;

[0074] Controlling the cleaning component to be filled with compressed air through the inlet of the first raw material sterilizer, and measuring the pressure value inside the first raw material sterilizer in real time through the pressure sensor;

[0075] When the pressure value reaches the specified pressure, the ball valve is controlled to open so that the compressed air carries the dust and is blown to the exhaust system 6 .

[0076] It should be understood that the compressed air is compressed air that has passed through an air filter to prevent bacteria from being brought into the compressed air to contaminate the raw material sterilizer. The specified pressure can be selected as 0.7MPa, which can not only ensure that the compressed air can effectively blow and carry dust to the exhaust system 6, but also ensure the normal operation of the first raw material sterilization feeding line and the safety of the equipment.

[0077] The control device can control the cleaning component to automatically clean the first raw material sterilizer, which not only reduces manual intervention, but also ensures the stability and consistency of the cleaning process, thereby improving the overall production efficiency. The exhaust pipe of the cleaning component is connected to the exhaust system 6, which can reduce indoor air pollution.

[0078] In some embodiments, the control module is configured to:

[0080] Controlling the second milk pump to transport the goat milk in the balancing tank to the first heat recovery section for heating to obtain 45° C. goat milk;

[0084] The goat milk at 75-85°C is cooled to 5°C by ice water at 2°C and then transported to the second milk silo.

[0085] The control module not only improves production efficiency but also ensures product quality and food safety through fine temperature control, liquid level adjustment and time management of the pasteurizer.

[0086] In some embodiments, the sterilization section is connected to the balancing cylinder via a reversing valve, and the control module is in communication with the reversing valve; the control module is configured as follows:

[0087] When the sterilization temperature of the sterilization section is lower than a preset temperature, the reversing valve is controlled to allow the goat milk in the sterilization section to return to the balancing cylinder.

[0088] It should be understood that the reversing valve is a directional control valve with two or more flow forms and two or more outlets. The reversing valve realizes connection or disconnection by changing the relative position of the valve core and the valve body, thereby controlling the start, stop or reversal of the actuator. A temperature sensor is also provided in the sterilization section to detect the temperature. The reversing valve is controlled by comparing the temperature in the sterilization section with the preset temperature to achieve precise control of the sterilization process.

[0089] By controlling the reversing valve through the control device to send insufficiently sterilized goat milk back to the balancing cylinder, it is possible to avoid producing unqualified milk powder products and improve product quality and safety.
