[0002] The original draft beer production room had multiple return air valves and CO2 valves, as well as auxiliary facilities such as air showers and shoe changing rooms. It occupied a large area, was cumbersome to operate, and took up a lot of employees' auxiliary production time.

[0003] Positive pressure rooms maintain an indoor pressure higher than the external pressure, ensuring that air can only flow from high-cleanliness areas to low-cleanliness areas. Outdoor air is filtered multiple times before being introduced into the room, maintaining the cleanliness of the indoor air and preventing pollutants from the external environment from entering the production area, thereby ensuring that product quality meets requirements.

[0004] Positive pressure chambers are used to control environmental hygiene and ensure the stability of the brewing process. The absolute cleanliness and dust-free, sterile environment within a positive pressure chamber prevents airborne contaminants from entering the wine, thus preventing unnecessary contamination. Furthermore, factors such as temperature, humidity, and airflow speed within the positive pressure chamber can be controlled to ensure an optimal aseptic bottling environment.

[0005] With the implementation of national policies advocating energy conservation and emission reduction, reducing the configuration of clean rooms, lowering investment in positive pressure rooms, improving market competitiveness, and achieving green and sustainable development have become the main needs of enterprises.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] It should be noted that the following embodiments can be combined where there is no conflict.

[0026] Please see Figure 1 Figure 2 and Figure 3 As shown, this utility model provides a positive pressure room for a beer bottling production line, including a room body 1 enclosed by a steel structure and glass, where a bottling machine 2 is placed for bottling beer. The positive pressure room is designed in accordance with the People's Republic of China National Standard GB50073-2001 "Code for Design of Cleanrooms". Compared with traditional positive pressure rooms, the positive pressure room provided by this utility model eliminates the need for return air ducts, shoe changing rooms, changing rooms, air showers, pass-through windows, and carbon dioxide exhaust systems. Because the bottling machine 2 can achieve automatic bottling, eliminating the above structures reduces the configuration of the cleanroom, lowers the project investment for the positive pressure room, and improves the competitiveness of the positive pressure room in the market.

[0027] In some embodiments, the steel structure is made of 100*100mm SUS304 stainless steel. The wall thickness of the stainless steel pipes for the columns and beams of the steel structure is required to be no less than 3mm, and argon arc welding is required during welding. The glass is made of single-sided 8mm tempered glass. The ceiling is made of 50mm double-sided stainless steel SUS304 extruded ester cleanroom insulation board, with a stainless steel plate thickness of 0.6mm and an insulation layer of extruded ester. After installation, the ceiling has a height difference of no less than 30mm.

[0028] The positive pressure room also includes an air supply system 4 located above the outside of the room body 1. The air supply system 4 includes an air conditioning unit 6 and two air intakes, wherein the first air intake 7 is located outdoors and the second air intake 8 is located indoors. The air intake switching of the two air intakes is automatically controlled by valves.

[0029] In this invention, "outdoor" and "indoor" refer to the outdoor and indoor areas of the wine bottling production line plant where the positive pressure room is located. In one embodiment, the first outdoor air intake 7 is located on the roof of the outdoor plant; the second indoor air intake 8 is located at a high altitude in the middle section of the plant.

[0030] The second air intake 8 is installed at a height not lower than 4m above the ground. In one embodiment, the second air intake 8 is installed at a height higher than 5m above the ground.

[0031] There is usually a temperature difference between the air temperature at high altitudes and the ground (or low altitudes). In winter, the second air intake 8 is used to obtain warm air from the high altitudes inside the room, which can reduce heating energy consumption. In summer, the first air intake 7 is used to obtain cool air from the high altitudes outside, which can reduce cooling energy consumption. The air intake switching between the two air intakes is automatically controlled by valves. By utilizing the temperature difference between different seasons, the air supply to the positive pressure room can be achieved, thereby achieving energy saving and realizing the company's green and sustainable development.

[0032] Furthermore, the air supply system 4 also includes an air outlet 3, which is located above the bottling machine 2. The airflow in the positive pressure room is vertically and unidirectionally ventilated through the air outlet 3. It should be understood that the air conditioning unit 6 is connected to the air outlet 3 via an air supply duct 12. In this invention, the air outlet 3 is located above the bottling machine 2, and the air supply duct 12 is also located above the bottling machine 2, and the air supply duct 12 is perpendicular to the horizontal plane. Therefore, a vertical and unidirectional airflow can be formed. The airflow velocity is consistent across the cross-section of the air supply duct 12, thus meeting the requirement of providing fresh air to the bottling machine 2. The airflow flows from the bottling machine 2 to other locations in the positive pressure room, which can prevent contaminants from contacting the bottling machine 2.

[0033] The air supply system 4 also includes an air conditioning unit 6, which is installed at a height of not less than 3.8m to facilitate the delivery of vertical and unidirectional airflow to the wine bottling machine 2 with a consistent flow rate; the height of the positive pressure room is not less than 4.3m to meet space requirements.

[0034] The air supply system 4 can acquire, heat, or cool fresh air, and then deliver it. Typically, the air supply system 4 is divided by the air conditioning unit 6. The air conditioning unit 6 has a fresh air section, a primary air section, a surface cooling section, and a water-blocking section between the air inlets; and an intermediate section, a heating section, a medium-efficiency section, and an outlet section between the air outlets 3, as detailed below. Figure 1 As shown; the air supply system is existing technology and will not be described in detail.

[0035] Because the bottling machine 2 generates water vapor during production and the air conditioning unit 6 operates, the internal and external air pressure of the positive pressure chamber is insufficient to allow the water vapor located above the positive pressure chamber to escape. Therefore, a water vapor exhaust system is also installed inside the positive pressure chamber. The water vapor exhaust system is located around the bottling machine 2 to absorb the water vapor generated by the bottling machine 2.

[0036] In some embodiments, the steam exhaust system includes a plurality of steam exhaust vents 9 disposed around the bottling machine 2, and the plurality of steam exhaust vents 9 are connected to the steam exhaust unit 13 through exhaust pipes 11. In this invention, four steam exhaust vents 9 are provided, respectively located at the four positions of the bottling machine 2.

[0037] Furthermore, such as Figure 3 As shown, the building 1 has a sealed glass door 5 for ventilation on each of its three sides. The sealed glass door 5 can serve as a fresh air outlet to ensure natural air circulation during beer production, and as an entrance and exit for staff.

[0038] In this invention, both the inner and outer sides of the glass are coated with an explosion-proof film, and the sealed glass door 5 is also coated with an explosion-proof film, which can prevent the glass from breaking due to excessive air pressure inside and outside the positive pressure room.

[0039] Furthermore, since the room 1 is entirely made of glass, it has good light transmission, allowing the lighting fixtures 10 to be installed outside the room 1. In one embodiment, the positive pressure room also includes lighting fixtures 10 located outside the room 1, with at least two lighting fixtures 10 installed on each side of the room 1, and the power of each lighting fixture 10 is not less than 150W, to ensure adequate illuminance inside the positive pressure room. Figure 3 As shown, Philips lighting fixtures can be used, with eight LED lights installed around the perimeter of the positive pressure chamber.

[0040] In some embodiments, the floor of the positive pressure chamber is made of stainless steel and is equipped with a stainless steel clean floor drain. The gap between the positive pressure chamber and the ground is no more than 15mm. In some embodiments, the floor and water-retaining embankment of the positive pressure chamber are made of 3mm thick stainless steel plate, material 316 stainless steel, to ensure that the design slope and water flow direction meet the design requirements. The stainless steel clean floor drain is welded to the stainless steel floor to facilitate drainage to the outside of the positive pressure chamber.

[0041] In some embodiments, the positive pressure room is equipped with at least a carbon dioxide sensor C, a temperature and humidity sensor W, a static pressure sensor Y1, and a differential pressure sensor D1. The carbon dioxide sensor C detects the carbon dioxide concentration within the positive pressure room, and the temperature and humidity sensor W detects the temperature and humidity. The static pressure sensor Y1 detects the room's static pressure, typically greater than or equal to 5 Pa. The differential pressure sensor D1 detects the pressure difference between the upper and lower surfaces within the positive pressure room. Using these sensors, real-time temperature, humidity, and CO2 alarm information can be displayed on a monitor.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
