Description

Technical Field

[0002] In the field of dairy product production, due to the separation of pastures and factories, fresh milk transport vehicles must be used to transfer raw milk from pastures to factories for production and processing. In addition to the high transportation cost, this traditional transportation method has many transportation links, which means that it takes 24-72 hours to complete the production of raw milk. Excessive storage time will reduce the freshness of raw milk and cause the loss of nutrients. Patent application No. 202021174392.0 discloses a closed fresh milk delivery system including a central control device and a delivery device, which includes a milking platform, a fresh milk buffer tank, a first set of duplex filters, a plate heat exchanger, a first raw milk temporary storage tank, a delivery pipeline, and a degassing tank, a second set of duplex filters, and a second raw milk temporary storage tank arranged in the factory; the central control device includes a PLC programmable logic controller, a central control computer, an I / O interface, a signal conversion module, a signal transmission module, and a field control cabinet. This solution enables fresh milk to enter the workshop directly from the pasture through a closed pipeline for processing, eliminating the need for raw milk transportation and storage in the traditional transportation mode. It can preserve the freshness of the raw milk to the greatest extent. It belongs to the field of dairy product processing equipment technology and is used to transport fresh milk.

[0003] However, although the above-mentioned production and processing method solves the problem of long-distance transportation by setting up a production and processing workshop near the ranch, this production method requires the fresh milk to be stored in a fresh milk buffer tank, a first raw milk temporary storage tank and a second raw milk temporary storage tank.

[0026] Please see Figure 1 and Figure 2A clean laminar flow hood type dairy production system, comprising an automatic milking platform 100, a clean laminar flow hood production unit 200 and a purification device 300, wherein the clean laminar flow hood production unit 200 is a preventive integrated closed clean chamber; the clean laminar flow hood production unit 200 at least comprises a laminar flow hood type milk supply valve group 210, a laminar flow hood type CIP cleaning device 220, a laminar flow hood type sterilizing device 230, a laminar flow hood type homogenizing device 240, a laminar flow hood type canning device 250, a laminar flow hood type boxing device 260 and a laminar flow hood type palletizing device 270 connected by a closed production pipeline 400, and the ..., and the laminar flow hood type milk supply valve group 210, a laminar flow hood type CIP cleaning device 220, a laminar flow hood type sterilizing device 230, a la The group 210 is connected to the milk outlet end of the automatic milking station 100; the air purification device 300 includes an elevated pipe 310, an air purification mechanism 320 and a filtering mechanism 340, the elevated pipe 310 is connected to the air purification mechanism 340 and the filtering mechanism 320 in sequence, and the other end of the filtering mechanism 320 is connected to the laminar flow hood type milk supply valve group 210, the laminar flow hood type CIP cleaning device 220, the laminar flow hood type sterilizing device 230, the laminar flow hood type homogenizing device 240, the laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270.

[0027] There are lactating cows raised in the pasture, and the pasture and its surrounding environment contain pasture odor, which leads to poor air quality in the pasture and its surrounding environment. The production and processing workshop of dairy products has special requirements for the environment, and it is necessary to ensure that the processing workshop is a dust-free and sterile workshop. Therefore, the production environment of the clean laminar flow hood production unit 200 in a preventive integrated closed clean chamber plays a preventive role, preventing pollutants such as pasture microorganisms and bad air from entering the clean laminar flow hood production unit 200. Specifically, the clean laminar flow hood production unit 200 includes necessary dairy production equipment used in the dairy production process, and the corresponding dairy production equipment is a new type of dairy production equipment with a clean laminar flow hood, and the clean laminar flow hood has a closed space, and the core components of the equipment and the closed laminar flow hood are highly integrated equipment. In other words, compared with traditional factories, the dairy production system set up by the ranch does not have a production plant. Instead, it directly adopts a number of integrated laminar flow hood-type dairy production equipment, which are arranged and connected according to the process design to realize the instant production and processing of dairy products in a highly clean environment. This greatly optimizes the dairy production system and improves the quality of dairy production.

[0028] The raw hot milk squeezed from the automatic milking platform 100 will be temporarily stored in the raw milk tank 110, which is used to temporarily store the raw hot milk of a large number of lactating cows in the pasture, and the temperature of the raw hot milk is about 36°C; the raw milk tank 110 is designed according to the milking volume of the automatic milking platform 100. It should be noted that in order to achieve preventive high-standard dairy product production, this solution designs a problem milk prevention detection system on the milking platform and uses the raw milk tank 110 to temporarily store dairy products. Before entering the production process, the raw milk paper quality is further ensured through secondary prevention detection, so as to adopt a preventive production system to improve the quality of dairy products.

[0029] The laminar flow hood type milk supply valve group 210 includes a milk supply valve group and a clean laminar flow hood mounted on the outside of the milk supply valve group. The milk supply valve group and the clean laminar flow hood are integrated and integrated during the preparation and production process; the laminar flow hood type milk supply valve group 210 is used to extract the raw hot milk in the raw milk tank 110 and transport the raw hot milk to subsequent production equipment; and the clean laminar flow hood of the laminar flow hood type milk supply valve group 210 is designed to form an integrated closed clean chamber, and the production equipment and its internal environment are in contact with non-clean air or microorganisms and other substances in the ranch.

[0030] The laminar flow hood type sterilization device 230 is used to sterilize materials, including pasteurization and high-temperature sterilization. Specifically, the laminar flow hood type sterilization device includes a sterilization device and a clean laminar flow hood mounted on the outside of the sterilization device. The sterilization device and the clean laminar flow hood are integrated into an integrated arrangement. The integrated processing can effectively save production space and optimize the internal layout space of the sterilization clean laminar flow hood. At the same time, the closed and integrated laminar flow hood type sterilization device 230 can prevent the production equipment and its internal environment from contacting with non-clean air or microorganisms in the pasture, thereby reducing production risks and ensuring the quality of dairy product production.

[0031] The laminar flow hood homogenizing device 240 comprises a homogenizing device and a clean laminar flow hood sleeved outside the homogenizing device. The homogenizing device and the clean laminar flow hood are integrated and integrated during the production process. The laminar flow hood homogenizing device 240 is used to homogenize the processed hot milk. The laminar flow hood homogenizing device 240 is an integrated closed clean chamber to prevent contact with the air of the pasture.

[0032] The laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270 all have an integrated enclosed clean chamber, a clean laminar flow hood is arranged on the outside, and they are integrated and integrated during the preparation and production process; this prevents the production equipment and its internal environment from contacting with non-clean air or microorganisms and other substances in the pasture, thereby reducing production risks and ensuring the quality of dairy product production.

[0033] In order to avoid sucking bad air from the pasture and its surrounding environment into the clean laminar flow hood production unit, the present application adopts the method of obtaining clean air at high altitude in the pasture. Specifically, the elevated pipe 310 is set, and the elevated pipe 310 has a preset height of 30-60 meters, and the air at this height is extracted to effectively prevent pasture dust, microorganisms and other pollutants from entering the production environment;

[0034] The air purification mechanism 320 is used to further clean the high-altitude air, and has the function of deodorizing and purifying the air, reducing dust, microorganisms and other pollutants in the extracted air. The air purified by the air purification mechanism 320 enters the laminar flow hood type milk supply valve group 210, the laminar flow hood type CIP cleaning device 220, the laminar flow hood type sterilization device 230, the laminar flow hood type homogenizing device 240, the laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270, so that the production air in each device is a dust-free and sterile air environment to reduce the risk of production contamination.

[0035] There are two connection modes of the air purification mechanism 320, namely, mode 1 (parallel mode), mode 2 (series mode) and mode 3 (parallel mode + series mode): Mode 1: The air cleaned by the air purification mechanism 320 enters the laminar flow hood type milk supply valve group 210, the laminar flow hood type CIP cleaning device 220, the laminar flow hood type sterilizing device 230, the laminar flow hood type homogenizing device 240, the laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270 respectively; after purifying the laminar flow hood type milk supply valve group 210, the air is returned to the air purification mechanism 320 through the laminar flow hood type milk supply valve group 210 to clean the laminar flow hood type CIP cleaning device 220. After the device 220 is purified, the air is returned to the purification mechanism 320 through the laminar flow hood type CIP cleaning device 220; after the laminar flow hood type sterilization device 230 is purified, the air is returned to the purification mechanism 320 through the laminar flow hood type sterilization device 230; after the laminar flow hood type canning device 250 is purified, the air is returned to the purification mechanism 320 through the laminar flow hood type canning device 250; after the laminar flow hood type boxing device 260 is purified, the air is returned to the purification mechanism 320 through the laminar flow hood type boxing device 260; after the laminar flow hood type palletizing device 270 is purified, the air is returned to the purification mechanism 320 through the laminar flow hood type palletizing device 270. The production cost of this method is high. Method 2: The air cleaned by the air purification mechanism 320 enters the laminar flow hood type milk supply valve group 210, the laminar flow hood type CIP cleaning device 220, the laminar flow hood type sterilization device 230, the laminar flow hood type homogenizing device 240, the laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270 in sequence, and then flows back to the air purification mechanism 320 through the laminar flow hood type palletizing device 270. The production cost of this method 2 is low, but the cleanliness of the air is lower than that of method 1. Method three: The air cleaned by the air purification mechanism 320 enters the laminar flow hood homogenizing device 240 and the laminar flow hood canning device 250 respectively. The clean air entering from the laminar flow hood homogenizing device 240 enters the sterilizing device, the laminar flow hood CIP cleaning device 220 and the laminar flow hood milk supply valve group 210 in turn, and then flows back to the air purification mechanism 320 through the laminar flow hood milk supply valve group 210. The clean air entering from the laminar flow hood canning device 250 enters the laminar flow hood boxing device 260 and the laminar flow hood palletizing device 270 in turn, and then flows back to the air purification mechanism 320 through the laminar flow hood palletizing device 270. This method three ensures the air cleanliness of the partial clean laminar flow hood production unit 200, meets the dust-free and sterile environment, and has a low production cost, and is more energy-saving and environmentally friendly.

[0036] The filter device 340 is mainly used to filter large particles of floating dust in the air. If there is sandstorm weather, there are many large particles of floating dust (sand and stones) in the air, and dust removal is required through the filter device 340 to ensure that the air entering the clean laminar flow hood production unit 200 is dust-free air. Specifically, the filter device can be a three-effect filter. The specific structure is referred to in relevant technical literature and will not be described here. Specifically, the filter device 340 can be arranged on the top of the laminar flow hood type milk supply valve group 210, the laminar flow hood type CIP cleaning device 220, the laminar flow hood type sterilization device 230, the laminar flow hood type homogenizing device 240, the laminar flow hood type canning device 250, the laminar flow hood type boxing device 260 and the laminar flow hood type palletizing device 270.

[0037] The effect achieved:

[0038] (1) The raw hot milk squeezed out by the automatic milking station 100 directly enters the clean laminar flow hood production unit 200 for hot milk processing and production, thereby realizing the timely production of raw hot milk and avoiding the secondary or multiple heating of the raw hot milk, which would lead to the decline of the quality of the dairy products and make it difficult to obtain high-standard dairy products; at the same time, the production process adopts the production and processing method at the milk source to realize the instant completion of the processing of the raw hot milk in 2 hours to obtain high-quality dairy products (compared with the traditional processing method, which takes 24-72 hours to complete the production), avoiding the long-distance transportation of the raw hot milk, improving the production efficiency, and greatly reducing the energy consumption.

[0039] (2) By installing the overhead pipe 310 and the air purification mechanism 320, the air at high altitude of the pasture is extracted to avoid extracting the odorous air in and around the pasture. At the same time, the clean laminar flow hood production unit 200 is installed. The production unit is a preventive integrated closed clean chamber, which can effectively prevent pasture dust, microorganisms and other pollutants from entering the production equipment and production environment, thereby further improving the production quality of dairy products.

[0040] Preferably, the automatic milking station 100 is provided with a raw milk tank 110, the inlet of the raw milk tank 110 is connected to the milk outlet of the automatic milking station 100, and is used for temporarily storing raw hot milk; generally, the raw hot milk squeezed from the automatic milking station 100 is directly sent to the laminar flow hood type milk supply valve group 210 to process and produce the raw hot milk, but when a large amount of raw hot milk is squeezed, the laminar flow hood type milk supply valve group cannot process and produce all the raw hot milk, and the remaining raw hot milk squeezed from the automatic milking station 100 will be temporarily stored in the raw milk tank 110, which is used to temporarily store the raw hot milk of a large number of lactating cows in the pasture, and the temperature of the raw hot milk is about 36°C.

[0041] Furthermore, since the structures of the laminar flow hood type milk supply valve group, the laminar flow hood type CIP cleaning device and the laminar flow hood type sterilizing device are mainly composed of interlaced pipes, in one embodiment, the laminar flow hood type milk supply valve group, the laminar flow hood type CIP cleaning device and the laminar flow hood type sterilizing device are integrated on the side wall of the clean laminar flow hood. Specifically, the pipeline parts of the laminar flow hood type milk supply valve group, the laminar flow hood type CIP cleaning device and the laminar flow hood type sterilizing device are integrated on the side wall of the clean laminar flow hood by design, which is conducive to saving the installation space of each device and reducing the equipment footprint.

[0042] Furthermore, in order to improve the stability of equipment installation and reduce the vibration of equipment operation, in one embodiment, the laminar flow hood type homogenizing device, the laminar flow hood type canning device, the laminar flow hood type boxing device and the laminar flow hood type palletizing device are integrated and arranged on the bottom plate of the clean laminar flow hood; further, the laminar flow hood type homogenizing device, the laminar flow hood type canning device and the laminar flow hood type boxing device are all arranged at the center position of the bottom plate of the clean laminar flow hood. In this way, since this part of the equipment is large in size and has a strong structural integrity, in order to ensure installation stability, it is more conducive to the stability of installation to install it at the center position of the bottom plate of the clean laminar flow hood; further, a reinforcing support is arranged at the center position of the bottom plate of the clean laminar flow hood, and each support corresponds to the bottom leg of the corresponding installation equipment one by one.

[0043] As a further description, the automatic milking station 100 is provided with a milk cup 120 and a preventive alarm device 130 matched with the milk cup 120, and the preventive alarm device 130 includes a conductivity meter 131, an alarm 132 and a control device 133, and the conductivity meter 131 is arranged on the milk cup 120, and the conductivity meter 131, the alarm 132 and the control device 133 are electrically connected. The conductivity of raw hot milk (35℃-37℃) is 7ms / cm-10ms / cm. This conductivity range reflects the freshness and thermal stability of milk and is one of the important indicators for measuring its quality. The level of conductivity can indirectly indicate the content of ion components in milk, and then reflect the freshness of milk and possible health problems. Therefore, by setting the conductivity meter 131, the conductivity of the raw hot milk is detected in real time. For example, when the conductivity of the raw hot milk is detected to be more than 10ms / cm, it may indicate that the raw milk is diseased, and some lactating cows have mastitis, which leads to the increase of NaCl ions in the raw hot milk, which will cause the conductivity to rise. The detected conductivity value is transmitted to the control device 133. When the conductivity value exceeds the preset conductivity value (10ms / cm), an alarm signal is issued through the alarm 132. The alarm signal is a flashing dazzling light or a sound. The preventive alarm device 130 can monitor the conductivity of the raw hot milk in real time to prevent the raw hot milk of poor quality from entering the raw milk tank 110.

[0044] Preferably, the milk cup 120 is provided with an automatic cup removal mechanism, which is electrically connected to the alarm 132 and is used to determine the quality of the raw milk according to the periodic feedback information of the preventive alarm device 130 (i.e., when the conductivity of the real-time raw hot milk exceeds the preset conductivity value, feedback information is issued), and to stop transporting the bad raw hot milk in the milk cup 120 to the raw milk tank 110 through the cup removal operation in time.

[0045] Specifically, the automatic cup removal mechanism 140 includes a first infusion pipe, a first automatic milk delivery valve, a second infusion pipe, a second automatic milk delivery valve and a detection milk pipe. The inlet of the first infusion pipe is connected to the milk cup 120, and the outlet of the first infusion pipe is connected to the raw milk tank 110. The first automatic milk delivery valve is arranged in the first infusion pipe. The first automatic milk delivery valve controls the circulation of the raw hot milk in the first infusion pipe. If the raw hot milk is of good quality, the first infusion pipe is in a circulation state, and the first automatic milk delivery valve is electrically connected to the preventive alarm device 130. The feedback signal emitted by the preventive alarm device 130 controls the opening and closing of the first automatic milk delivery valve. The second infusion pipe is arranged in parallel with the first infusion pipe, the inlet of the second infusion pipe is connected to the milk cup 120, the outlet of the second infusion pipe is connected to the detection milk pipe, the second automatic milk delivery valve is arranged in the second infusion pipe, and the second automatic milk delivery valve controls the flow of raw hot milk in the second infusion pipe. If the raw hot milk is of poor quality, the second infusion pipe is in a flow state, the first infusion pipe is in a closed state, and the poor raw hot milk in the second infusion pipe flows into the detection milk pipe, and the second automatic milk delivery valve is electrically connected to the preventive alarm device 130, and the feedback signal sent by the preventive alarm device 130 controls the opening and closing of the second automatic milk delivery valve. The automatic cup removal mechanism is arranged, and the raw hot milk of poor quality is transferred to the detection milk pipe in time through the feedback signal sent by the preventive alarm device 130, so as to further detect the raw hot milk.

[0046] Furthermore, the laminar flow hood type milk supply valve group 210 is provided with a dead angle free flow pool and an automatic protein detector. The dead angle free flow pool is a chamber with a transparent cover, and the automatic protein detector is installed on the dead angle free flow pool. The dead angle free flow pool has a smooth inner wall without dead angles, and the material will not be attached to the inner wall surface when passing through, which can effectively reduce the probability of dairy microorganisms; the automatic protein detector is installed on the transparent cover of the dead angle free flow pool. The automatic protein detector uses the optical detection principle to detect the dairy material passing through the dead angle free flow pool, and determines the protein content of the raw hot milk, so as to select the RO membrane to start and adjust the dairy protein index according to the dairy protein requirements.

[0047] Furthermore, the clean laminar flow hood production unit further includes a laminar flow hood type RO membrane filter device 280, one end of which is connected to the laminar flow hood type milk supply valve group 210, and the other end is connected to the laminar flow hood type sterilization device 230. The laminar flow hood type RO membrane filter device 280 is an RO membrane filter device and a clean laminar flow hood integrated to prevent pasture air from entering the laminar flow hood type RO membrane filter device 280. If the automatic protein detector detects that the raw hot milk protein value does not meet the production standard, the laminar flow hood type RO membrane filter device 280 is started for concentration to ensure that the raw milk meets the production requirements of dairy products.

[0048] Furthermore, the laminar flow hood type milk supply valve group 210 is provided with an automatic sampling device for automatically detecting the quality value of the raw hot milk. Within a preset time period, the raw hot milk in the laminar flow hood type milk supply valve group 210 is regularly collected, and the quality value of the raw hot milk is detected in real time, so as to detect the quality of the raw milk in real time and preventively control the production quality.

[0049] Preferably, the closed production pipeline 400 includes an energy pipeline 410, a material pipeline 420 and a waste pipeline 430. The energy pipeline 410 is a pipeline for providing electricity, heat, etc. to ensure the normal operation of the preventive clean laminar flow hood type dairy production system. The material pipeline 420 is arranged downwardly from the production start end to the production end and is inclined to the horizontal plane to ensure that the raw hot milk can circulate quickly. At the same time, the material pipeline 420 is smooth and does not stick to the medical-grade pipeline of the raw hot milk. When the material pipeline 420 is arranged downwardly, it is ensured that the raw hot milk does not hang on the wall of the material pipeline 420, reducing the raw hot milk in the material pipeline 420. Microorganisms are also bred and it is also convenient to clean; the material pipeline 420 is provided with several sections of material pipes, and the adjacent sections of the material pipes are connected by automatic welding technology; the automatic welding technology can effectively reduce the burrs at the welding joints at the joints of the material pipes, thereby ensuring the smoothness of the inner wall of the material pipe, reducing the probability of material hanging on the wall when passing through, and facilitating thorough cleaning. Specifically, the material pipeline 420 has an inclination angle of 3°-5°. Adjusting the inclination angle through the installation process is ideal for material flow and will not cause difficulty in pipeline connection.

[0050] Specifically, the inclination angle of the material pipeline 420 is 3°.

[0051] Specifically, the inclination angle of the material pipeline 420 is 4°.

[0052] Specifically, the inclination angle of the material pipeline 420 is 5°.

[0053] Furthermore, in order to efficiently and energy-savingly utilize high-altitude clean air, the air purification mechanism 320 includes a first air purification group 321 and a second air purification group 323 connected to the elevated pipe 310, the first air purification group 321 is connected to a first gas branch pipe 322, and the gas outlet of the first gas branch pipe 322 is sequentially connected to the laminar flow hood canning device 250, the laminar flow hood homogenizing device 240, the sterilization device, the laminar flow hood CIP cleaning device 220 and the laminar flow hood milk supply valve group 210; the production sanitation environment level of each device entered by the first air purification group 321 is higher, and the power and air cleanliness setting level of the first air purification group are higher than those of the second air purification group 323; it should be noted that each device is provided with an air conditioner, and the first gas branch pipe 322 is connected to the corresponding air conditioning system of each device, and then the clean air is transported into the device. The second clean air group 323 is connected to the second gas branch pipe 324, and the gas outlet of the second gas branch pipe 324 is sequentially connected to the laminar flow hood type box packing device 260 and the laminar flow hood type palletizing device 270. Since the laminar flow hood type box packing device 260 and the laminar flow hood type palletizing device 270 belong to the packaging process after the dairy product processing, the environmental sanitation level requirements for the equipment are not very high. Therefore, in order to reduce energy consumption, the second clean air group 323 is used to purify the air, and the purified air is sequentially sent to the laminar flow hood type box packing device 260 and the laminar flow hood type palletizing device 270 through the second gas branch pipe 324. The air enters the interior of the equipment to ensure that the internal production environment has air with a certain sanitation level to meet production needs and achieve energy-saving and environmental protection effects.

[0054] Furthermore, the filtering mechanism 340 includes a shell 341, a first screen 342 and a second screen 343. One end of the shell 341 is connected to the fan 330, and the other end is connected to the air purification mechanism 320. The first screen 342 and the second screen 343 are arranged in the shell 341. The first screen 342 is arranged on the side close to the fan 330, and the second screen 343 is arranged on the side close to the air purification mechanism 320. The aperture of the first screen 342 is larger than the aperture of the second screen 343. When large particles of floating dust (wind and sand) enter the filtering mechanism 340 through the fan, since the aperture of the first screen 342 is larger than the aperture of the second screen 343, the first screen 342 filters the larger particles of floating dust (wind and sand) in the air, such as wind and sand particles of 0.2mm-0.25mm, and passes through the second screen 343 to filter the smaller particles of floating dust in the air, such as wind and sand particles of 0.1mm-0.2mm. Since the air purification mechanism 320 has a higher precision, the filtering mechanism 340 is easier to disassemble than the air purification mechanism 320, and the staff can regularly replace the first screen 342 and the second screen 343.
