Description

Technical Field

[0001] The utility model relates to the technical field of HVAC, and particularly relates to an air distribution system for a drying and fermentation workshop. Background Art

[0002] Animal cured and dried foods are traditional foods with local characteristics in China. However, their processing methods and production processes are relatively primitive and backward, mainly manual pickling and natural drying. The production scale is small, the cycle is long, and the product quality is greatly affected by natural conditions, which cannot meet the needs of food industrial production. Moreover, food hygiene is difficult to guarantee. Adopting cold air drying is a special processing method that simulates the natural environment in winter, with low temperature, low humidity, high wind speed, rapid dehydration and drying, and at the same time forms flavors.

[0003] The use of supply and exhaust air systems for the processing of animal cured and dried foods has been widely applied. However, in many current food factory workshops, due to reasons such as the workshop building structure and equipment layout, the workshop height is too high, and the internal net height dimension exceeds 5 meters or 6 meters. The traditional air duct structure will cause uneven air distribution in the workshop and insufficient air volume for the food materials hanging at high places. Content of the Utility Model

[0004] The purpose of the utility model is to provide an air distribution system for a drying and fermentation workshop to solve the problem of uneven air volume in the workshop.

[0005] The utility model provides an air distribution system for a drying and fermentation workshop, which includes an air handling unit, supply air ducts, return air ducts, supply air outlets, return air inlets and air valves; the supply air ducts are divided into upper supply air ducts and lower supply air ducts according to the supply air direction.

[0007] Further, the connection mode between the upper supply air duct, the lower supply air duct and the air handling unit is star connection.

[0008] Further, the return air inlets are arranged on both the upper and lower surfaces of the return air duct; there is more than one return air duct, and each return air duct has only one open end communicating with the air handling unit.

[0009] Further, the connection mode between the return air duct and the air handling unit is star connection.

[0010] Further, the cross-sectional area of the supply air duct decreases along the supply air direction inside the duct.

[0011] Further, a deflector is provided below the supply air outlet.

[0012] Furthermore, the air return opening is a disc-shaped air opening.

[0013] Furthermore, the air handling unit is installed outside the workshop.

[0014] Furthermore, the air valve is installed at the opening end of the air supply duct.

[0015] Compared with the existing air distribution system, the present utility model has at least the following beneficial effects;

[0016] In the air distribution system proposed in this embodiment, simultaneous air supply from above and below can enable the air in the entire room to achieve full circulation, thereby making the indoor temperature more uniform, avoiding dead corners and pressure differences, and improving the indoor air quality.

[0024] The air distribution system of the air-drying and fermentation workshop of the present utility model will be described in more detail below in conjunction with the schematic diagrams, in which the preferred embodiments of the present utility model are shown. It should be understood that those skilled in the art can modify the present utility model described herein while still achieving the advantageous effects of the present utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the present utility model.

[0025] For clarity, not all features of the actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would obscure the present utility model with unnecessary details. It should be considered that in the development of any actual embodiment, numerous implementation details must be made to achieve the specific goals of the developer, such as changing from one embodiment to another according to the relevant system or commercial limitations. Additionally, it should be considered that such development work may be complex and time-consuming, but it is only routine work for those skilled in the art.

[0026] The present utility model will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of facilitating and clearly assisting in explaining the purpose of the embodiments of the present utility model.

[0027] As Figures 1 to 5 shown, an air distribution system of an air-drying and fermentation workshop in this embodiment includes an air handling unit 2, a supply air duct 3, a return air duct 4, supply air outlets 5, return air inlets 6, air valves 8, a first duct 9, a second duct 10, and a deflector 11.

[0028] The air distribution system is installed in the air-drying and fermentation workshop 1. As Figure 2 described, there is a trolley 7 with food hanging in the workshop.

[0029] The air handling unit is installed on the top of the workshop and is connected to the supply air duct and the return air duct through two different ports.

[0030] The supply air duct group includes two upper supply air ducts with one end open, two lower supply air ducts with one end open, and a first duct with five ports; one port of the first duct is connected to the air handling unit, and the other four ports are respectively connected to the four supply air ducts.

[0031] The four supply air ducts are fixed in pairs on two opposite side walls of the workshop in the combination of one upper supply air duct and one lower supply air duct. The open ends of the supply air ducts are connected to the first duct outside the workshop by bolts; the supply air outlets are arranged on the upper surface of the upper supply air duct, and the air supply direction is upward; the supply air outlets are arranged on the lower surface of the open end of the lower supply air duct, and the air supply direction is downward.

[0032] The air supply duct is a contraction type duct, whose cross-sectional area gradually decreases along the air supply direction inside the duct. As the cross-sectional area decreases, the air flow velocity inside the duct will increase correspondingly. This helps to optimize the pressure distribution inside the duct, making the pressure drop more uniform and reducing the local pressure loss. The contraction type duct also helps to improve the distribution of indoor air, making the air flow into the workshop more uniform, so that the temperature inside the workshop is more uniform.

[0033] As Figure 4 shown, the air supply outlet 5 is a conical air supply outlet, which is fixed on the surface of the air supply duct by rivets; there is also a deflector 11 fixed to the bottom of the side wall of the workshop by screws below the air supply outlet 5 (as Figure 5 shown). The deflector 11 can adjust the wind speed, and by adjusting the angle of the deflector 11, the distribution of the air flow can be controlled, avoiding too high or too low wind speed in local areas and achieving a more uniform indoor temperature distribution.

[0034] The return air duct group includes two return air ducts with one end open and a second pipe with three ports; one port of the second pipe is connected to the air handling unit, and the other two ports are respectively connected to the ports of the return air ducts.

[0035] The two return air ducts are fixed to two opposite side walls of the workshop, and the fixed positions are below the upper air supply duct and above the lower air supply duct. The open ends of the return air ducts are connected to the second pipe outside the workshop by bolts; the return air inlets are arranged on the upper and lower surfaces of the return air ducts.

[0036] Please refer to Figure 6 , the return air inlet 4 is a disk-shaped return air inlet with adjustable height, and is connected to the return air duct by flange through threads. By rotating the screw 42 to adjust the relative height between the disk 41 and the flange to achieve the adjustment of the air volume, the distribution of the indoor air flow can be improved, avoiding too high or too low wind speed in local areas and achieving a more uniform temperature distribution; in different seasons or different time periods, the indoor heat load may change, and the return air inlet with adjustable air volume can adapt to these changes and keep the indoor temperature stable.

[0037] The air valve is installed at the port of the air supply duct located outside the workshop and is connected to the air supply duct by bolts.

[0038] The air supply duct, the return air duct, the first pipe, and the second pipe are all composed of one or more pipes combined. The connection method between multiple pipes is bolt connection.

[0039] In summary, in an air distribution system of a drying and fermentation workshop provided by an embodiment of the present utility model, simultaneous upper and lower air supply can make the air in the whole room fully circulated, so that the indoor temperature is more uniform, avoiding dead corners and pressure differences, and improving the indoor air quality.

[0040] The return air inlets of the middle return air duct are arranged vertically, enabling the upper air supply to form a convection with the upper return air inlets and the lower air supply outlets to form a convection with the lower return air inlets, thus forming an up-and-down convection. The adjustment of the up-and-down air directions can better carry out air convection, making the indoor air fresher and eliminating odors.

[0041] The above are only the preferred embodiments of the present invention and do not impose any restrictive effect on the present invention. Any person skilled in the relevant technical field, without departing from the technical solution of the present invention, making any form of equivalent substitution or modification and other changes to the technical solution and technical content disclosed by the present invention, shall fall within the scope of the technical solution of the present invention and still be within the protection scope of the present invention.
