DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] Referring to the accompanying drawings: the starch stirring and processing device comprises a stirring tank 1, a reducer 2 is arranged on the tank cover of the stirring tank 1, and the reducer 2 is connected to a stirrer 21 placed in the stirring tank 1, and further comprises

[0023] A feeding unit 3, used for conveying starch into the mixing tank 1; and

[0024] The water heating unit 4 is used to heat the purified water and transport the heated water into the stirring tank 1, and allows the stirring tank 1 to be flushed with the produced hot water after the stirring tank 1 completes the slurry production; and

[0025] The weighing unit 5 is used to weigh the mixing tank 1. The principle of the utility model is that 80° hot water is prefabricated by the water heating unit 4, cold purified water is pre-added in the mixing tank 1, and then starch is transported into the mixing tank 1 through the feeding unit 3, and the weighing module 5 will display the weight change of the mixing tank 1 after the water and starch enter, so as to accurately control the amount of feed, and then the reducer 2 starts to drive the stirrer 21 to rotate for stirring, and after the starch and the cold purified water are evenly mixed, the water heating unit 4 adds hot water to the mixing tank 1, so that the material temperature rises to 80°, and then continues to stir, the temperature increase increases the expansion degree of starch, the solubility increases, and starch gelatinization is achieved, and after the stirring is completed, cold water is continued to be added to the mixing tank 1, and the stirring is continued, and the temperature of the material in the mixing tank 1 is cooled to 65° by adding cold water, so as to complete the material preparation, and this method can accurately control the amount of water and starch, and can achieve starch gelatinization, and at the same time, the hot water produced by the water heating unit 4 can also be used as a flushing medium during flushing, so as to increase the flushing effect.

[0026] The feeding unit 3 includes a vacuum feeder 31, a material barrel 32, and a suction pipe 33. The vacuum feeder 31 is arranged on the tank cover of the mixing tank 1. The material barrel 32 is used to store starch and is provided with a cross bottom car 321 with wheels. One end of the suction pipe 33 is arranged on the material barrel 32 and the other end is arranged on the vacuum feeder 31. The vacuum feeder 31 attracts materials through negative pressure, which has the characteristics of high efficiency and energy saving, and can greatly reduce the loss and waste of materials. The material barrel 32 is used to store starch. The cross bottom car 321 is convenient for moving the barrel 32, which is convenient when transferring the barrel 32. The suction pipe 33 is used to connect the barrel 32 and the vacuum feeder 31, so that when the vacuum feeder 31 is working, the starch enters the suction pipe 33 after leaving the barrel 32, and is transported to the vacuum feeder 31 through the suction pipe 33. Finally, the vacuum feeder 31 transports the starch to the mixing tank 1. At the same time, a temperature sensor is provided in the mixing tank 1 to detect the slurry temperature.

[0027] The suction pipe 33 is a steel wire lined hose with a smooth inner wall, so that powder will not be stored on the inner wall of the pipe, thereby preventing waste of materials.

[0028] The water heating unit 4 includes a water storage tank 41 and a water delivery pipe 42. The water storage tank 41 is used to store purified water. One end of the water delivery pipe 42 is arranged on the water storage tank 41 and the other end is arranged on the stirring tank 1 to transfer the purified water that has been heated from the water storage tank 41 to the stirring tank 1. A drainage pipe 411 is arranged at the lower water outlet of the water storage tank 41. A spray pipe 6 is arranged between the stirring tank 1 and the water storage tank 41. The two ends of the spray pipe 6 extend into the stirring tank 1 and the water storage tank 41 respectively, and the ends extending into the inside are both provided with spray heads 61. The non-drainage end of the drainage pipe 411 is connected to the water inlet end of the horizontal circulation pump 7. The water outlet end of the horizontal circulation pump 7 is provided with a water pipe 71 that is simultaneously connected to the spray pipe 6 and realizes water circulation. A tubular heat exchanger 711 is arranged on the water pipe 71 to heat the water passing through. The water storage tank 41 is used to store purified water. The water in the tank is heated by the tubular heat exchanger. The water circulation is realized by the device 711, that is, the water circulation is realized by using the drainage pipe 411, the horizontal circulation pump 7 and the spray pipe 6. During the circulation process, the water passes through the tubular heat exchanger 711, so as to heat the water by absorbing the temperature of the tubular heat exchanger 711, and two second vertical water pumps 4111 are arranged on the drainage pipe 411, that is, one second vertical water pump 4111 is close to the drainage end, and the other second vertical water pump 4111 is close to the horizontal circulation pump 7. The water delivery pipe 42 is used to transport the hot water in the water storage tank 41 to the mixing tank 1, so as to add hot water to the mixing tank 1. The spray pipe 6 can flush and clean the water storage tank 41 or the mixing tank 1 after completing the starch preparation. During the flushing, the hot water is allowed to enter in a dispersed state through the spray head 61, so as to ensure the uniformity of the slurry flushing. At the same time, the water pipe 71 is provided with a pressure sensor and a temperature sensor, so as to realize the monitoring of temperature and pressure.

[0029] The spray pipe 6 is provided with a first vertical water pump 62 which is symmetrically distributed on both sides of the water pipe 71, and a one-way valve 63 is arranged on the spray pipe 6 between the two first vertical water pumps 62. The first vertical water pump 62 is started when flushing the water storage tank 41 or the inside of the mixing tank 1, and one of the two first vertical water pumps 62 is started selectively, so that the flushing water can flow in the corresponding direction during flushing. The one-way valve 63 is located on one side of the first vertical water pump 62 used to pump water into the water storage tank 41, so that the one-way valve 63 will not open when the water flows into the mixing tank 1, thereby preventing part of the water from flowing into the water storage tank 41.

[0030] An insulation sleeve 412 is provided on the outer peripheral surface of the water storage tank 41 to keep the heated water in the water storage tank 41 warm and avoid rapid temperature loss in a static state.

[0031] A jacket 11 is provided on the outer peripheral surface of the stirring tank 1, and a gap for inputting water is formed between the jacket 11 and the outer surface of the stirring tank 1. Hot water or cold water can be added in the formed gap. When insulation is required, hot water is added in the gap to keep the stirring tank warm; when cooling is required, cold water is added in the gap to cool the stirring tank. At the same time, a polyurethane insulation layer is provided on the outside of the jacket 11 to prevent people from being scalded.

[0032] The weighing unit 5 includes two weighing modules 51, which are arranged on the supporting feet of the mixing tank 1, so that the mixing tank 1 can completely release its own weight on the two weighing modules 51, and the weighing modules 51 can respond quickly when the weight changes in the tank.

[0033] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
