[0002] The production process of dried rice noodles mainly includes steps of raw material preparation, pulp grinding, steaming, pre-drying and aging, cutting and drying. Among them, the powder sheet aging process is a very important step in the production process of dried rice noodles. Since the cut strips will not stick to the cutting knife after the powder sheet is aged, and the quality of the aged powder sheet is significantly improved, the aging process is essential in the production of dried rice noodles.

[0003] The aging process has strict requirements in the production process of dried rice noodles. Among them, the important factor determining the aging speed of dried rice noodles is temperature. When the temperature in the aging machine drops to a certain value, the aging speed of dried rice noodles is the fastest. Therefore, the aging machine needs to be equipped with a special refrigeration system to achieve temperature control of the aging machine.

[0004] Most of the existing aging machine refrigeration systems need to be equipped with an in-machine refrigeration unit, an outdoor compressor unit and a cooling water tower. Such a refrigeration system has more equipment, is more troublesome to install, and has higher production costs and labor costs. Therefore, it is necessary to design a new type of low-temperature aging machine. Content of the Utility Model

Detailed implementation mode

[0025] The following will further elaborate on the present utility model in detail.

[0026] As Figure 1 shown, a water-cooled low-temperature aging machine includes an aging box 6;

[0027] Inside the aging box 6, there are arranged an aging machine body 1 for placing the powder tablets to be aged, a heat exchange device 2, and a circulation fan 3;

[0028] Outside the aging box 6, there is a cold water source 4. The cold water source 4 is connected to the heat exchange device 2 through a pipeline to form a closed-loop circuit;

[0029] Between the heat exchange device 2 and the cold water source 4, there is a water pump 5. The water pump 5 is used to drive the cold water source 4 to supply cold water to the heat exchange device 2;

[0030] The heat exchange device 2 is fixedly connected to the aging box 6 and is used to perform heat exchange between the cold water in the heat exchange device 2 and the air inside the aging box 6 to reduce the temperature of the air inside the aging box 6; Specifically, the heat exchange device 2 is a water-cooled radiator.

[0031] The circulation fan 3 is arranged on one side of the heat exchange device 2 and is used to blow the cooled air towards the aging machine body 1.

[0032] Both the heat exchange device 2 and the circulation fan 3 are installed above the aging machine body 1. The circulation fan 3 blows the cooled air from top to bottom towards the aging machine body 1. Inside the aging box 6, there is a wind guide plate 7. The wind guide plate 7 is inclined and installed on one side of the top of the aging box 6. The wind guide plate 7 is arranged opposite to the circulation fan 3 and is used to guide the air blown out by the circulation fan 3 to the aging machine body 1.

[0033] The aging machine body 1 is installed at the bottom of the aging box 6. Spaces allowing the air flow to circulate are left on both sides of the aging machine body 1. A flow regulating valve 81 is arranged on the pipeline between the heat exchange device 2 and the cold water source 4. Inside the aging box 6, there is a temperature sensor 61. The temperature sensor 61 is connected to the flow regulating valve 81. The temperature sensor 61 is used to detect the temperature of the air after heat exchange by the heat exchange device 2.

[0034] Between the heat exchange device 2 and the cold water source 4, there are a water supply pipe 8 and a water return pipe 9. One end of the water supply pipe 8 is connected to the heat exchange device 2, and the other end is connected to the cold water source 4. The water pump 5 is installed on the water supply pipe 8; One end of the water return pipe 9 is connected to the heat exchange device 2, and the other end is connected to the cold water source 4. The water supply pipe 8 is equipped with a flow regulating valve 81. The flow regulating valve 81 is connected to the temperature sensor 61 and is used to receive the signal sent by the temperature sensor 61 to adjust the water flow rate of the water supply pipe 8.

[0035] A refrigerant is added to the cold water source 4 to adjust the freezing point of the water and prevent the cold water from freezing and blocking the water supply pipe.

[0036] In the aging machine body 1, there is a conveying chain 12 for placing the powder flakes to be aged, and the conveying chain 12 is arranged in a wave shape. As Figure 2 shown, in the aging machine body 1, there is a frame 11. On the frame 11, there are a conveying chain 12 and a plurality of rollers 13. The plurality of rollers 13 are arranged up and down in sequence in the horizontal direction. The conveying chain 12 is arranged to fold back and forth around the plurality of rollers 13, and the included angle formed by the folding back of the conveying chain 12 is 60 degrees. Compared with the structure of the straight conveying line adopted by the aging machines on the market at present, adopting the folded-back conveying chain 12 can extend the product aging time without increasing the length of the aging machine.

[0037] The working principle of the present utility model: After the dried rice noodle flakes are pre-dried, they enter the aging machine body 1. The water pump 5 is started to convey the cold water in the cold water source 4 to the heat exchange device 2. After the cold water enters the heat exchange device 2, the temperature of the heat exchange device 2 is reduced. The circulation fan 3 is started to drive the air flow. The flowing air exchanges heat with the heat exchange device 2 and the cold water and then the temperature is reduced to become cold air. The cold air is then blown by the circulation fan 3 into the aging machine body 1 to reduce the temperature in the aging machine body 1 and accelerate the aging speed of the powder flakes. The cold air blown out by the circulation fan 3 changes the wind direction through the air deflector 7, so that the cold air flows downward to avoid the wind blowing to the wall and blowing back to disrupt the air flow. After the cold air passes through the aging machine body 1, it is drawn back by the circulation fan 3 to the heat exchange device 2 above for heat exchange.

[0038] The aging temperature of the aging machine body 1 needs to be stabilized within a certain temperature range. When the temperature in the aging chamber 6 is not within this temperature range, the temperature sensor 61 feeds back a signal to the flow regulating valve 81. The flow regulating valve 81 controls the flow rate of the supplied cold water, thereby regulating the heat exchange temperature of the heat exchange device 2 and controlling the temperature in the aging machine body 1. When the temperature in the aging machine body 1 rises, the temperature sensor 61 feeds back a signal to the flow regulating valve 81 to increase the cold water flow rate, accelerate the heat exchange between the heat exchange device 2 and the air in the aging chamber 6, generate cold air with a lower temperature, and reduce the temperature in the aging machine body 1; when the temperature in the aging machine body 1 is relatively low, the temperature sensor 61 feeds back a signal to the flow regulating valve 81, and the flow regulating valve 81 reduces the cold water flow rate, thereby slowing down the heat exchange between the heat exchange device 2 and the air in the aging chamber 6, generating cold air with a relatively higher temperature, and increasing the temperature in the aging machine body 1, and so on in a cycle.

[0039] The present utility model has few supporting devices, is convenient to install, and effectively reduces the production cost.

[0040] The above embodiments are the preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present utility model shall be equivalent replacement methods and are all included in the protection scope of the present utility model.
