Description

Technical Field

[0001] This utility model relates to the field of workshop technology, specifically a dust-free and dehumidified workshop for producing piglet milk powder. Background Technology

[0002] As a core source of nutrition for early-weaned piglets, the quality of piglet milk powder directly affects the healthy growth of piglets and the economic benefits of pig farming. The main components of piglet milk powder include whey protein, fat, vitamins, and minerals. These ingredients, especially lactose and minerals, have extremely strong hygroscopic properties.

[0003] Currently, it is known that excessively high humidity in the work area (e.g., >60% RH) can easily cause milk powder to absorb moisture and clump, affecting its flowability and reconstitution properties, and accelerating nutritional deterioration. Secondly, warm and humid environments are prone to the growth of microorganisms, leading to excessive microbial levels in the product and harming the health of piglets. Thirdly, the cross-flow of personnel and materials and insufficient regional isolation in traditional workshops can easily cause cross-contamination. Finally, external pollutants can easily enter the clean area through gaps. Existing technologies typically lack reasonable layout designs, making it difficult to continuously maintain the low-humidity, dust-free environment required for high-standard production.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figure 1-3 This utility model provides a dust-free and dehumidified workshop for producing piglet milk powder, including a main workshop 1, an environmental control system, and a moisture-proof and dehumidification system. The interior of the main workshop 1 is divided into a negative pressure dust-free area and a non-negative pressure area by partition walls and airlocks 2. The negative pressure dust-free area includes a mixed work area and an independent and one-way personnel passage area. The non-negative pressure area includes a cargo shower 3, a raw material storage area 4, and a finished product storage area 5. The environmental control system is located in the negative pressure dust-free area and is used to maintain a stable positive pressure environment in the workshop. The moisture-proof and dehumidification system is located in the negative pressure dust-free area and is used to prevent external moisture intrusion and internal condensation, and to actively reduce the ambient humidity.

[0022] The personnel passage area includes a negative pressure buffer zone 9, a changing room 10, an air shower room 11, and an air shower passage 12, where personnel pass in one direction. The negative pressure buffer zone 9 is connected to the outside through the personnel entrance 13.

[0023] The mixing work area includes a pretreatment area 14, a batching and mixing production area 15, and a packaging area 16. The pretreatment area 14 is connected to the packaging area 16 via a personnel passage 17. The pretreatment area 14 is also connected to the air shower passage 12 and the raw material storage area 4. It should be noted that the main functions of the pretreatment area 14 include pretreatment, feeding, and central batching control, so that workers can work in the batching and mixing production area 15. A feeding channel, specifically an underground tunnel, is provided between the pretreatment area 14 and the batching and mixing production area 15.

[0024] based on Figure 1 As shown, airlocks 2 are provided between the negative pressure buffer zone 9 and the changing room 10, between the changing room 10 and the air shower 11, between the pretreatment area 14 and the air shower passage 12, between the pretreatment area 14 and the raw material storage area 4, between the personnel passage 17 and the packaging area 16, and between the raw material storage area 4 and the cargo air shower 3, so as to achieve the effect of sealing and connecting the corresponding areas. At the same time, it can be used in conjunction with the environmental control system and the moisture-proof and dehumidification system to further improve the working environment in the main body of the workshop 1 and avoid cross-contamination.

[0025] The environmental control system includes multiple negative pressure suction dust removal systems 6 and a filtration and air supply system 7. Each negative pressure suction dust removal system 6 is located at the top of the negative pressure cleanroom area and is connected to each other via ventilation ducts 8, the outlet of which extends outside the main body of the workroom 1. Each filtration and air supply system 7 is located at the bottom of the negative pressure area. Each filtration and air supply system 7 regulates the air supply volume, and each negative pressure suction dust removal system 6 regulates the exhaust volume to maintain a positive pressure of 5-10 Pa within the main body of the workroom relative to the external environment. The arrangement of the filtration and air supply systems 7 and the negative pressure suction dust removal systems 6 in the environmental control system maintains a positive pressure state inside the workshop, preventing external pollutants from entering. Therefore, each filtration and air supply system 7 is equipped with a high-efficiency particulate air (HEPA) filter using existing technology, which performs three-stage filtration of the air to ensure that the air cleanliness within the workshop reaches ISO 8 or higher standards. Furthermore, the cooperation between the filtration and air supply systems 7 and the negative pressure suction dust removal systems 6 ensures an air exchange rate of no less than 15 times per hour.

[0026] Furthermore, it should be noted that a negative pressure suction dust removal system 6 and a filter air supply system 7 are respectively arranged in the changing room 10, air shower room 11, pretreatment area 14, packaging area 16, and ingredient mixing area. Based on Figure 2 As shown, the air supply direction of the filtration and air supply system 7 is designed according to the cleanliness level from high to low, ensuring that the air always flows from the area with high cleanliness to the area with low cleanliness, avoiding backflow; while each negative pressure suction dust removal system 6 discharges dust to the outside of the main body of the work room 1 through the connected air supply duct, thereby achieving the effect of clean workshop.

[0027] A glass observation window 22 is provided in the partition wall between the pretreatment area 14 and the ingredient mixing production area 15 for staff to observe. This facilitates observation by staff, improving work efficiency and product quality.

[0028] The negative pressure cleanroom area is also equipped with a dehumidification and drying system, which includes multiple constant temperature and humidity air conditioners 18 and humidity monitoring and early warning devices 19 arranged within the negative pressure cleanroom area. The constant temperature and humidity air conditioners 18 and humidity monitoring and early warning devices 19 are electrically connected. It should be noted that the constant temperature and humidity air conditioners 18 are common mechanical equipment in existing factories and can be purchased on the market.

[0029] The cargo shower 3 is connected to the outside via cargo inlet 20. Furthermore, it should be noted that the channel through which goods enter via cargo inlet 20 is a material channel, which is separate from the personnel channel through personnel inlet 13. The entire material channel is transported by a closed conveyor belt or a dedicated passageway.

[0030] The finished product storage area 5 is connected to the packaging area 16, and the finished product storage area 5 has an exit 21 for personnel and goods to exit. An airlock 2 is also provided between the finished product storage area 5 and the packaging area 16.

[0031] Specifically, when workers are working, all airlocks 2 are closed to create a sealed space inside, making the entire production line a closed production line.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
