DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following is combined with Figures 1 - 5A further detailed description is given to the present utility model.

[0023] An embodiment of the present utility model discloses a water circulation cooling system.

[0024] Refer to Figure 1 、 Figure 3 A water circulation cooling system includes a cooling sleeve 1 which is sleeved outside the rear section of the auger conveyor pipe 2. The cooling sleeve 1 uses a double-layer hollow structure. The cooling sleeve 1 includes an inner pipe 3 and an outer pipe 4. An inlet 5 and an outlet 6 are arranged on the outer pipe 4. A cooling cavity 7 is arranged between the inner pipe 3 and the outer pipe 4. The cooling cavity 7 is externally connected to a water circulation device 8. A stirring and conveying shaft is arranged at the axial center position inside the auger conveyor pipe 2. Blades are arranged around the stirring and conveying shaft. The stirring and conveying shaft is driven by a motor. The dough is fed by the blades and conveyed.

[0025] Refer to Figure 3 、 Figure 5 Support columns 9 are distributed in the cooling cavity 7. Both ends of the support columns 9 are vertically fixed to the inner pipe 3 and the outer pipe 4 respectively, to support the double-layer hollow structure of the cooling sleeve 1, and at the same time transfer the heat of the inner pipe 3 to the cooling water in the cooling cavity 7, increasing the heat transfer area.

[0026] Refer to Figure 5 Both the support columns 9 and the inner pipe 3 are made of heat-conducting materials. The inner pipe 3 is in contact with the auger conveyor pipe 2, increasing the heat transfer area.

[0027] Refer to Figure 4 Hoops 10 are arranged on the outer sides of both ends of the cooling sleeve 1 and fastened through the hoops 10 to fix the cooling sleeve 1.

[0028] Refer to Figure 1 、 Figure 2 The water circulation device 8 includes a cooling water tank 11. The cooling water tank 11 is connected to the inlet 5 through a water inlet pipe 12. A high-pressure water pump 13 is arranged on the water inlet pipe 12. The cooling water tank 11 is connected to the outlet 6 through a water outlet pipe 14. A radiator 15 is arranged on the water outlet pipe 14 to realize the water circulation for heating and cooling.

[0029] Refer to Figure 1 、 Figure 2, a first temperature sensor 16 and a water level sensor 17 are arranged inside the cooling water tank 11. Both the first temperature sensor 16 and the water level sensor 17 are communicatively connected to a microcomputer controller 18 arranged on one side of the cooling water tank 11; a heat dissipation plate and a cooling fan 19 are arranged on one side of the cooling water tank 11; the cooling water tank 11 is communicated with a water supply pipe 20 and a drain pipe 21, and electromagnetic valves 22 are arranged on both the water supply pipe 20 and the drain pipe 21. The switch of the cooling fan 19 and the electromagnetic valves 22 are both communicatively connected to the microcomputer controller 18; the communicative connection is a kind of electrical connection. The first temperature sensor 16 and the water level sensor 17 in the cooling water tank 11 sense the temperature and the water volume. When the temperature is slightly higher than the set temperature value, the cooling fan 19 is started to cool down; when the temperature is much higher than the set temperature value, the first temperature sensor 16 sends out information, the microcomputer controller 18 receives the information and conveys an instruction to control the electromagnetic valve 22 at the position of the drain pipe 21 to open, and drain the water with too high temperature in the cooling water tank 11. The electromagnetic valve 22 at the position of the water supply pipe 20 is opened to add external cold water into the cooling water tank 11; when the water volume in the cooling water tank 11 is insufficient, the electromagnetic valve 22 at the position of the water supply pipe 20 is opened, and external cold water is replenished to keep the water temperature and volume in the cooling water tank 11 within a certain range.

[0030] Refer to Figure 1 , Figure 3 , Figure 4 , a second temperature sensor 23 is arranged inside the rear section of the auger conveying pipe 2. The second temperature sensor 23 is communicatively connected to the microcomputer controller 18, and the second temperature sensor 23 senses the temperature of the dough after cooling.

[0031] The implementation principle of the water circulation cooling system in an embodiment of the present utility model is as follows: In the embodiment of the present utility model, the water circulation cooling system is applied to the cooling and shaping of dough. The hollow cooling sleeve 1 is sleeved outside the auger conveying pipe 2, and cold water in the cooling water tank 11 is injected into the cooling cavity 7 of the cooling sleeve 1 through a high-pressure water pump 13. The warmed water in the cooling cavity 7 is dissipated heat through the radiator 15 and flows back to the cooling water tank 11. Thus, when the auger conveying pipe 2 conveys the dough, an uninterrupted cooling cycle work is carried out. The whole process is automatically controlled by a microcomputer controller, so that the water in the cooling water tank is automatically drained after heating up and the water tank is automatically replenished with water, always keeping the water temperature and volume in the cooling water tank within a certain range to ensure the smooth progress of water circulation cooling.
