Description

Technical Field

[0001] This utility model relates to the field of liquor brewing technology, specifically to an air-cooled condenser used in liquor brewing. Background Technology

[0002] In the process of brewing baijiu (Chinese liquor), the condenser is an indispensable key piece of equipment in the distillation stage. Its function is to cool and liquefy the high-temperature alcohol vapor produced by distillation into liquid liquor (raw liquor), which is convenient for collection and subsequent processing.

[0003] Currently, the liquor industry mainly uses condensation methods such as water cooling, air cooling, and natural cooling. Air cooling uses air as the cooling medium, with a fan forcibly dissipating heat. It features water conservation, environmental friendliness, simple structure, easy installation, low maintenance costs, and flexible installation. In operation, high-temperature alcohol vapor enters the condenser's internal pipes from the distillation pot. The fan starts, forcing external air to flow over the condenser's outer surface (finned tubes). The vapor transfers heat to the tube walls within the pipes, and then to the flowing air through the fins. The vapor temperature drops below the dew point, undergoing a phase change and condensing into liquid liquor. The liquid liquor flows out from the outlet under gravity, and the air carries away the heat before dissipating it into the environment.

[0004] Existing air-cooled condensers typically have an air inlet at the bottom of the casing and an air outlet duct fixedly connected to the top, with the fan installed inside the duct. This often results in sufficient cooling at the bottom of the heat exchange tubes, while the upper part suffers from poor heat dissipation, which can cause vapor to mix into the wine, leading to a decrease in alcohol recovery rate. Utility Model Content

[0005] This utility model provides an air-cooled condenser for baijiu brewing. By arranging air inlet plates in a staggered manner on both sides of the housing, it can achieve simultaneous air intake from the sides and bottom, making the airflow distribution uniform, avoiding dead corners, and solving the problems of poor heat dissipation and reduced liquor recovery rate mentioned in the background art.

[0006] This utility model provides the following technical solution: A wind-cooled condenser for baijiu brewing includes a housing, an air outlet pipe fixedly connected to the top of the housing, a negative pressure fan fixedly connected inside the air outlet pipe, and a distribution seat and a collection seat, both detachably connected to the housing. The distribution seat is located above the collection seat, and the distribution seat and the collection seat are connected by multiple condenser pipes. An air inlet pipe is fixedly connected to the distribution seat, and a liquid outlet pipe is fixedly connected to the collection seat. Multiple air inlet plates are respectively installed on both sides of the housing, and each air inlet plate has a ventilation slot. The air inlet plates on both sides are staggered.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Reference Figures 1-4A wind-cooled condenser for baijiu (Chinese liquor) brewing includes a housing 1. An air outlet duct 101 is fixedly connected to the top of the housing 1, and a negative pressure fan 102 is fixedly connected inside the air outlet duct 101. The negative pressure fan 102 is a BT35 axial flow fan used to draw air out of the housing 1. An air inlet 103 is provided at the bottom of the housing 1. A first dustproof net 4 is detachably connected to the outer wall of the air inlet 103. The first dustproof net 4 can be fixed to the bottom of the housing 1 with screws. L-plates are fixedly connected to the left, right, and rear sides of the outer wall of the air inlet 103. The first dustproof net 4 is slidably connected in a groove composed of three sets of L-plates, thus supporting and fixing the first dustproof net 4, facilitating installation and removal, and improving maintenance efficiency. It also includes a distributor seat 2 and a collection seat 201, both detachably connected to the housing 1. Both the distributor seat 2 and the collection seat 201 are made of 316L stainless steel, with the distributor seat 2 positioned above the collection seat 201. The distributor seat 2 and the collection seat 201 are connected by multiple condenser pipes 202, preferably made of copper. There are two to fifteen condenser pipes 202, preferably eleven. The condenser pipes 202 have a serpentine structure, which increases the residence time of the alcohol vapor in the condenser pipes 202, thereby improving the alcohol recovery rate. An air inlet pipe 203 is fixedly connected to the top of the distributor seat 2, and a liquid outlet pipe 204 is fixedly connected to the collection seat 201. In use, alcohol vapor enters the distributor seat 2 through the air inlet pipe 203 and then flows along the multiple condenser pipes 202 into the collection seat 201. During this flow, heat is transferred to the pipe walls, and the flowing air passing over the pipe walls lowers the vapor temperature below the dew point, causing a phase change and condensation into liquid alcohol. Liquid wine flows out from the outlet pipe 204 under gravity, and after the air carries away the heat, it is discharged into the environment through the air outlet pipe 101. In addition, a collection chamber is provided in the collection seat 201. The bottom of the collection chamber is set at an incline. The inlet of the outlet pipe 204 is connected to the lowest point of the collection chamber, which helps to drain the wine completely. The inner diameter of the outlet pipe 204 is larger than the inner diameter of the air inlet pipe 203. Multiple air inlet plates 3 are provided, with two to ten, preferably six, installed on both sides of the box body 1, that is, three air inlet plates 3 on each side. Ventilation slots are provided on the multiple air inlet plates 3. The air inlet plates 3 on both sides are staggered, which can increase the air volume on the side of the box body 1 and improve the cooling effect of the upper condenser pipe 202.

[0020] During use, air inlet plates 3 are fixedly connected to both sides of the housing 1. The outlet of the air inlet plates 3 gradually approaches the condenser pipe 202 from top to bottom, which can cool specific positions of the condenser pipe 202. When used in conjunction with bottom ventilation, it ensures that air flows evenly across the entire heat exchange surface, thereby improving condensation efficiency, stability and equipment life.

[0021] Reference Figure 3The length of the air inlet plate 3 on the same side increases from top to bottom, and the outlet of the air inlet plate 3 is inclined upward. While achieving directional cooling, the air flows from bottom to top, which can increase the contact area of ​​the condenser tube 202 and improve the performance.

[0022] Reference Figure 3 A guide plate 301 is fixedly connected inside the ventilation slot. A guide blade is fixedly connected to the end of the guide plate 301 facing the air inlet. It can divide the air entering the ventilation slot. By utilizing the inclination of the ventilation slot outlet, the two airflows can disperse after colliding when they blow towards the condenser pipe 202, which has a turbulence effect.

[0023] Reference Figures 1-3 Air inlet slots 104 are provided on both sides of the housing 1. The air inlet end of the air inlet plate 3 is connected to the corresponding air inlet slot 104. A second dustproof net 5 is detachably connected to the outer wall of the air inlet slot 104. Here, it is preferable to detach the second dustproof net 5 to the outer wall of the air inlet slot 104 with screws. In use, by installing the second dustproof net 5 on the air inlet slot 104, dust and other objects can be reduced from entering the housing 1, thereby reducing the number of maintenance times for the housing 1 and the condenser pipe 202 and improving the performance.

[0024] Components not described in detail in this article are existing technologies.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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.
