Description

Technical Field

[0001] The invention relates to a temperature control device for a dough mixer. Background Art

[0002] At present, dough kneading is a key process for noodle manufacturers, and temperature has a direct impact on the quality of dough kneading. The temperature requirements for dough kneading water vary in different seasons. Generally, warm water is required in winter and cold water is required in other seasons. But in fact, when the dough kneading barrel is working, the temperature will rise and be difficult to control, which has a great impact on the taste and quality of noodles. The current dough kneading machine lacks a device that can flexibly control the temperature of the dough kneading barrel. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a temperature control device for a dough mixer which has a reasonable structure and can flexibly adjust the temperature of a dough barrel.

[0004] In order to solve the above technical problems, the present invention provides a temperature control device for a dough mixer;

[0005] It includes a heating coil, a water pump, a temperature sensor, a water inlet control valve, and at least one recovery pool. The water inlet control valve has a first water inlet hole, a second water inlet hole and a first water outlet hole. When the water inlet control valve is in a first working position, a passage is formed between the first water inlet hole and the first water outlet hole. When the water inlet control valve is in a second working position, a passage is formed between the second water inlet hole and the first water outlet hole. The first water inlet hole is connected to a cold water source through a pipeline, the second water inlet hole is connected to a hot water source through a pipeline, the first water outlet hole of the water inlet control valve is connected to the starting end of the heating coil through a pipeline, and the end of the heating coil is connected to the recovery pool through a pipeline. The heating coil is installed on the outer side of the dough barrel of the dough mixer, the water pump is installed on the pipeline between the water inlet control valve and the heating coil, and the temperature sensor is installed on the outer side of the dough barrel of the dough mixer. The temperature sensor senses the temperature of the dough barrel of the dough mixer.

[0006] After adopting such a structure, when the temperature of the dough mixing barrel is higher than the temperature required by the process, the water flowing out of the cold water source passes through the heating coil to take away the excess heat in the dough mixing barrel, so that the dough mixing barrel maintains a constant temperature working environment; when the temperature of the dough mixing barrel is lower than the temperature required by the process, the water flowing out of the hot water source passes through the heating coil to maintain the temperature of the dough mixing barrel constant and meet the process requirements.

[0007] The beneficial effects of the temperature control device of the dough mixer are: meeting the different needs of customers, solving the problems encountered by pasta production enterprises in the process of producing noodles, improving the taste, quality and production efficiency of dough strips, and reducing enterprise costs.

[0008] The hot water source of the temperature control device of this dough mixer includes a hot water tank and a heating pipe. Water is stored in the hot water tank, and the heating pipe is located inside the hot water tank. The cold water source includes a cold water tank, and water is also stored in the cold water tank. With such a structure, the structures of the hot water source and the cold water source are specified.

[0009] The temperature control device of this dough mixer also includes a water outlet control valve. The recovery tank also includes a hot water recovery tank and a cold water recovery tank. The water outlet control valve has a third inlet hole, a second outlet hole, and a third outlet hole. When the water outlet control valve is in the first working position, a passage is formed between the third inlet hole and the second outlet. When the water outlet control valve is in the second working position, a passage is formed between the third inlet hole and the third outlet hole. The second outlet hole is connected to the hot water recovery tank through a pipeline, and the third outlet hole is connected to the cold water recovery tank through a pipeline. The third inlet hole of the water outlet control valve is connected to the end of the heating coil through a pipeline. With such a structure, the water outlet control valve can cooperate with the hot water recovery tank and the cold water recovery tank to complete the separate recovery of cold and hot water.

[0010] The hot water recovery tank of the temperature control device of this dough mixer is connected to the hot water tank, and the cold water recovery tank is connected to the cold water tank. With such a structure, the cooling water of the temperature control device of this dough mixer forms a cycle.

[0011] The temperature control device of this dough mixer also includes a reversing valve. The reversing valve has a first reversing port, a second reversing port, a third reversing port, and a fourth reversing port. The first reversing port is connected to the water outlet of the water pump through a pipeline, the second reversing port is connected to the third inlet hole of the water outlet control valve through a pipeline, the third reversing port is connected to the beginning end of the heating coil through a pipeline, and the fourth reversing port is connected to the end of the heating coil through a pipeline.

[0012] When the reversing valve is in the first working position, the first reversing port is connected to the third reversing port, and the second reversing port is connected to the fourth reversing port. When the reversing valve is in the second working position, the first reversing port is connected to the fourth reversing port, and the second reversing port is connected to the third reversing port.

[0013] Every time the water pump of the temperature control device of this dough mixer runs for 3 minutes, the working position of the reversing valve switches between the first working position and the second working position once.

[0014] With such a structure, the flow direction of the circulating water in the heating coil can be changed regularly, making the water temperature in the heating coil more uniform, and then ensuring that the temperature change of the dough bucket is more linear. Description of the Drawings

[0017] As Figures 1 to 2 shown

[0018] The temperature control device of the dough mixer includes a heating coil 4, a water pump 11, a temperature sensor 5, a reversing valve 7, an inlet control valve 1, an outlet control valve 6, a hot water recovery tank 8 and a cold water recovery tank 9.

[0019] The inlet control valve 1 has a first inlet hole A1, a second inlet hole B1 and a first outlet hole C1. When the inlet control valve 1 is in the first working position, a passage is formed between the first inlet hole A1 and the first outlet. When the inlet control valve 1 is in the second working position, a passage is formed between the second inlet hole B1 and the first outlet hole C1.

[0020] The cold water source includes a cold water tank 2 with water stored therein. The first inlet hole A1 is connected to the cold water source through a pipeline. The hot water source includes a hot water tank 3a and a heating pipe 3b with water stored in the hot water tank 3a. The heating pipe 3b is located inside the hot water tank 3a. The second inlet hole B1 is connected to the hot water source through a pipeline.

[0021] The heating coil 4 is fixedly installed on the outer side surface of the dough bucket 10 of the dough mixer through a bracket. The water pump 11 is installed on the pipeline between the first outlet hole C1 of the inlet control valve 1 and the heating coil 4. The temperature sensor 5 is installed on the outer side surface of the dough bucket 10 of the dough mixer, and the temperature sensor 5 senses the temperature of the dough bucket 10 of the dough mixer.

[0022] The outlet control valve 6 has a third inlet hole A6, a second outlet hole B6 and a third outlet hole C6. When the outlet control valve 6 is in the first working position, a passage is formed between the third inlet hole A6 and the second outlet. When the outlet control valve 6 is in the second working position, a passage is formed between the third inlet hole A6 and the third outlet hole C6. The second outlet hole B6 is connected to the hot water recovery tank 8 through a pipeline, and the third outlet hole C6 is connected to the cold water recovery tank 9 through a pipeline.

[0023] The hot water recovery tank 8 is connected to the hot water tank 3a, and the cold water recovery tank 9 is connected to the cold water tank 2.

[0024] The reversing valve 7 has a first reversing port A7, a second reversing port B7, a third reversing port C7 and a fourth reversing port D7. The first reversing port A7 is connected to the outlet of the water pump 11 through a pipeline. The second reversing port B7 is connected to the third inlet hole A6 of the outlet control valve 6 through a pipeline. The third reversing port C7 is connected to the starting end of the heating coil 4 through a pipeline. The fourth reversing port D7 is connected to the end of the heating coil 4 through a pipeline;

[0025] When the reversing valve 7 is in the first working position, the first reversing port A7 is communicated with the third reversing port C7, and the second reversing port B7 is communicated with the fourth reversing port D7. When the reversing valve 7 is in the second working position, the first reversing port A7 is communicated with the fourth reversing port D7, and the second reversing port B7 is communicated with the third reversing port C7.

[0026] When the dough mixer is in use, the temperature sensor 5 senses the temperature of the dough bucket 10, and the temperature sensor 5 transmits the temperature signal to an external control circuit. If the temperature sensor 5 senses that the temperature of the dough bucket 10 is too high, the inlet control valve 1 is controlled to be in the first working position, and the outlet control valve 6 is controlled to be in the second working position. The low-temperature water in the cold water tank 2 sequentially passes through the water pump 11, the heating coil 4, and the cold water recovery tank 9 and then flows back into the cold water tank 2 again to form a cycle for cooling the dough bucket 10 of the dough mixer.

[0027] Similarly, if the temperature sensor 5 senses that the temperature of the dough bucket 10 is too low, the inlet control valve 1 is controlled to be in the second working position, and the outlet control valve 6 is controlled to be in the first working position. The water in the hot water tank 3a is heated by the heating pipe 3b to become high-temperature water. The high-temperature water in the hot water tank 3a sequentially passes through the water pump 11, the heating coil 4, and the hot water recovery tank 8 and then flows back into the hot water tank 3a again to form a cycle for heating the dough bucket 10 of the dough mixer.

[0028] Regardless of whether the temperature control device of the dough mixer is in the heating cycle or the cooling cycle, the reversing valve 7 switches between the first working position and the second working position every 3 minutes when the water pump 11 is running.

[0029] The above is only one implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several variations and improvements can be made, and these should also be regarded as belonging to the protection scope of the present invention.
