Through the setting of the variable-frequency axial-flow fan, the present application can inhale ambient air from bottom to top during the operation of the variable-frequency axial-flow fan, so as to condense the wine in the fin tube 3 and cool the water in the water tray 4 with excessive temperature. In order to improve the air-cooling effect, the present application has obtained through experimental comparison that 4 air-cooling ports 11 are set in the present application, so that under the action of the air-cooling component 13, the flow direction of the gas in the water tray 4 can be balanced, the water temperature tends to be balanced, and its practical performance is improved.

[0023] like Figure 2 In the present application, an air inlet 20 is provided at the center of the water pan 4, and a preheating device is also provided in the water pan 4, wherein the preheating device comprises a heat exchange tube 8, and the heat exchange tube 8 is arranged in a ring shape or an arc shape at the bottom of the outer wall of the water pan 4 near the air inlet 20; wherein the long line of the center line of the heat exchange tube 8 coincides with the center line between the air cooling port 11, and the present application can diffuse the steam entering the water pan 4 in the water body through the arrangement of the heat exchange tube 8, so that the water body can be preheated evenly under the action of the steam. The heat exchange tube 8 described in the present application is connected to the steam tube 7. The steam tube 7 described in the present application is provided with a steam tap 16. The steam tap 16 is provided with 3-5 steam tap pipes 17, and the output end of the steam tap pipe 17 is connected to the middle of the heat exchange tube 8; and a meter and a steam control valve for controlling the steam intake are installed on the steam tube 7. Through experimental comparison, it is found that the present application has 4 steam tap pipes 17, and the long line along the axis thereof coincides with the symmetry line of the "V"-shaped plate between the air cooling port 11. The heating efficiency of the water body preheating is increased by more than 8% compared with directly introducing steam into the water body.

[0024] Embodiment 2 Based on the above embodiment, this embodiment is to improve the heat exchange efficiency between steam and water. Figure 3-4 The heat exchanger tube 8 of the present application is provided with a heat exchange wire mesh 9, and the heat exchange wire mesh 9 is formed by interweaving metal wires so that there are staggered gaps inside. A partition tube 14 is provided on the inner top of the heat exchanger tube 8, and air holes or gaps are provided on the side wall of the partition tube 14; the partition tube 14 separates the heat exchange wire mesh 9 to maintain the steam channel at the top of the heat exchanger tube 8. The partition tube 14 can be a metal tube or a spring tube with a hollow tube wall. A steam outlet hole is provided at the bottom of the heat exchanger tube 8, and the steam outlet hole is arranged at a position of the heat exchanger tube 8 close to the fin tube 3, and the direction of the steam outlet hole is arranged toward the fin tube 3. The steam flows out from the steam vent and passes through the water in the water pan, and then acts on the fin tube 3, thereby improving the preheating effect on the water in the water pan 4 and the fin tube 3. The present application sets a heat exchange wire mesh 9 in the heat exchange tube 8 and combines the setting of the steam vent. On the one hand, it can improve the utilization rate of steam and increase the heat exchange of steam. On the other hand, it increases the contact between steam and water and improves the preheating effect of the water. Through experimental comparison, it is concluded that the heat exchange wire mesh 9 is set in the heat exchange tube 8 of the present application, which can reduce the energy consumption required for the preheating process of the water by 5%.

[0025] Embodiment 3 On the basis of the above embodiment, in order to prevent the steam from overflowing from the air inlet 20, the present embodiment Figure 5 The top of the air inlet 20 described in the present application is also provided with an annular baffle 18, and a plurality of guide grooves 19 are opened on the annular baffle 18, wherein the height of the annular baffle 18 is 5-8 cm. On the basis of the above structure, the height of the guide groove 19 described in the present application is 2-3 cm, and the guide groove 19 is arranged away from the air outlet position of the heat exchange tube 8. Under the action of the annular baffle 18 and the guide groove 19, the steam enters the water in the water tray from the heat exchange tube 8, and blows through the fin tube 3 through the action of the air cooling component 13 (low gear operation). During the preheating process, the cooled air is discharged from the guide groove 19 and the air inlet 20. It can prevent the overflow of water vapor and promote the discharge of cold air, thereby improving the preheating effect of steam. After experimental verification, the annular baffle 18 and the guide groove 19 can increase the preheating efficiency of the equipment by 15%.

[0026] Control group 1 On the basis of Example 2, the difference between this control group and Example 1 is that the spacer 14 is not in contact with the inner wall of the heat exchange tube 8; through experimental comparison, it is found that when the water in the water tray 4 is preheated to the required production temperature, the steam consumption required for preheating the water through the heat exchange tube 8 in the control group 1 is increased by 3% compared with the steam consumption required for preheating the water through the heat exchange tube 8 of the present application.

[0027] Control group 2 On the basis of Example 2, the difference between this control group and Example 1 is that a tubular body formed by interweaving metal mesh screens is provided in the heat exchange tube 8; through experimental comparison, it is found that when the water in the water tray 4 is preheated to the required production temperature, the steam consumption required for preheating the water through the heat exchange tube 8 in the control group 2 is increased by 7% compared with the steam consumption required for preheating the water through the heat exchange tube 8 of the present application.

[0028] Control group three On the basis of Example 2, the difference between this control group and Example 1 is that no heat exchange mesh 9 is provided in the heat exchange tube 8; through experimental comparison, it is found that when the water in the water tray 4 is preheated to the required production temperature, the steam consumption required for preheating the water through the heat exchange tube 8 in the control group three is increased by 12% compared with the steam consumption required for preheating the water through the heat exchange tube 8 of the present application.

[0029] In summary, the present application provides an air cooler with a preheating function. A heat exchange mesh 9 is provided in the heat exchange tube 8. A steam outlet is provided at the bottom of the heat exchange tube 8. The heat exchange mesh 9 is connected to the inner wall of the heat exchange tube 8 through a spacer 14 on one side of the heat exchange mesh 9 close to the output end of the steam tube 7. On the one hand, the utilization rate of steam in the preheating process of the present application can be improved, and the heat exchange between the steam and the heat exchange tube 8 can be increased. On the other hand, the contact between the steam and the water body can be increased, and the preheating effect of the water body can be improved. During the preheating process of the present application, the air cooling component is stopped or below the operating state. The controller is operated to set the parameters of the air-cooling component 13, the temperature monitor and the control valve. Steam is injected into the water pan 4 through the steam pipe 7 to heat the water in the water pan 4. When heated to the required production temperature, the control valve switch is opened through the preset program. By controlling the air exhaust volume of the air-cooling component and the air intake volume of the steam pipe, the water pan is maintained at a temperature of 35-45°C in the low temperature environment in winter to slowly cool the wine. That is, the preheating temperature of the water pan 4 is monitored by the temperature monitor. When the preheating temperature reaches 35°C, the steam pipe valve is closed. The air exhaust volume of the air-cooling component 13 is controlled to keep the condensing temperature at the optimal temperature state of 35-45°C. The present invention can significantly improve the preheating efficiency of the equipment by improving the preheating structure of the water cooler, so that the equipment can also maintain the optimal temperature conditions in the winter environment, the quality of the brewed liquor is more stable, the waste of the first liquor is reduced, and the brewing output is increased.
