Description

Technical Field

[0001] The invention relates to the technical field of milling, in particular to a low-temperature mill with intelligent temperature control and a use method thereof. Background Art

[0002] In the process of food processing, it is necessary to process grains such as wheat and corn into flour. The traditional device for processing flour is a stone mill, which is now gradually replaced by modern flour mills. In the process of using modern stone mill flour mills to grind flour, it is necessary to grind off the outer husk of the grain, including the pericarp, seed coat, outer endosperm layer, etc., leaving the internal endosperm. A grinding machine is needed in the processing process. The existing grinding machines mostly use rollers to roll and crush the materials, and apply pressure to the rollers during rolling. The rolled materials are crushed by the pressure. This method has the inconvenience of pressure regulation and will produce more materials that are not sufficiently crushed. At the same time, in the existing grinding machine during the grinding process, due to the collision and friction between the materials and the machine and the heat generated by the machine, the temperature of the materials rises during the grinding process, which easily causes the loss of nutrients in materials such as grains, resulting in unnecessary waste.

[0003] In the prior art, there is a wheat flour machine with a low-temperature grinding function, such as application number CN201721654184.9, and its technical solution is as follows: a grinding box is arranged on the top of the base, support frames are arranged on both sides of the top of the grinding box, a support plate is arranged on the top of the support frame, a material storage bin is arranged on the top of the support plate, a motor is arranged on the top of the grinding box, a reducer is arranged at the bottom of the motor, a rotating shaft is connected to the bottom of the reducer, and the left and right sides of the rotating shaft are connected to the grinding roller through a connecting rod, a grinding disc is arranged at the bottom of the grinding disc, a filter screen is arranged at the bottom of the filter screen, and a material receiving box is arranged at the bottom of the inner cavity of the grinding box, and the inner cavity of the material receiving box is provided with two groups of cooling plates with the same structure arranged obliquely, and the two groups of cooling plates are symmetrically arranged. The invention has the characteristics of low-temperature grinding, can reduce the damage to wheat nutrition, improve wheat grinding efficiency, and can improve grinding quality.

[0004] Another example is a brown rice low-temperature milling machine with application number CN202121946099.6, and its technical solution is as follows: it includes a bottom plate, a refrigerator is provided on the top of the bottom plate, a grinding box is provided on the top of the refrigerator, a shell is provided on the outer surface of the grinding box, a cavity is formed between the grinding box and the shell, and a pump body is fixedly installed on one side of the refrigerator. The utility model transports the cooling water inside the refrigerator to the inside of the cavity through the pump body, and the cooling water in the cavity cools the brown rice inside the grinding box to prevent the loss of nutrients inside the brown rice. Then the cooling water flows into the refrigerator from the second connecting pipe and is cooled again. The motor output shaft rotates to drive the rotating rod to rotate, and then drives the grinding wheel to rotate to grind the brown rice. During the grinding process, the scraper rotates to move the brown rice on the side wall of the grinding box to the center of the grinding box, thereby improving the grinding efficiency and preventing uneven grinding. The device is conducive to reducing the temperature during brown rice grinding, reducing the loss of nutrients in the brown rice, and improving the grinding efficiency.

[0005] However, the existing low-temperature grinding machine only cools the grains when they come into contact with the cooling plate. The refrigeration effect of the grains cannot be guaranteed after the grains enter the collection box, and the grinding amount of the material cannot be controlled. The excessive load generated by grinding causes the temperature to rise quickly, which further leads to unsatisfactory low-temperature control effect.

[0006] In view of this, we conducted in-depth research on the above issues, which led to the present case.

A hydraulic press 9 is arranged in the middle, and a telescopic rod 10 is connected to the bottom of the hydraulic press 9, a support frame 11 is arranged at the bottom of the telescopic rod 10, and limit rods 14 are arranged on the left and right sides of the support frame 11, and a grinding block 13 is arranged below the support frame 11, a grinding groove 15 is arranged in the middle of the mill housing 1, and a collection box 17 is arranged at the bottom of the grinding groove 15, temperature sensors 19 are arranged on the left and right sides of the mill housing 1, and the temperature sensors 19 are connected to the first pump 20 and the second pump 25.

[0052] The telescopic rod 10 penetrates the upper surface of the mill housing 1, and a driving motor 12 is fixedly installed at the bottom of the support frame 11, and the left and right sides of the driving motor 12 are connected to the bottom surface of the support frame 11 through a tripod. A grinding block 13 is connected and installed at the output end at the bottom of the driving motor 12, and the grinding block 13 is located above the grinding groove 15 to be able to move up and down. An insulation layer 16 is arranged on the outside of the grinding groove 15, and a heat-conducting sleeve 23 is installed around the outside of the insulation layer 16. Starting the hydraulic press 9 can drive the telescopic rod 10 to extend and retract, and then drive the support frame 11 and the connected driving motor 12 to move up and down, providing mechanical power for the grinding block 13 to move the distance of contacting the grinding groove 15. When the grinding block 13 is away from the grinding groove 15, a position space is provided for the discharge pipe 7 to discharge the material into the grinding groove 15.

A heat conduction plate 26 is arranged above the cooling box 3, and the heat conduction plate 26 is located at the bottom of the aggregate box 17. A first pump 20 is arranged above the left side of the cooling box 3, and the first pump 20 is connected to a liquid outlet pipe 21, and the upper part of the liquid outlet pipe 21 is connected to the left side of the cooling pipe 22.

When the second pump 25 is started, the coolant 18 in the cooling pipe 22 can be discharged back to the cooling box 3 through the right liquid inlet pipe 24, providing the recycling of the coolant 18, which is energy-saving and environmentally friendly. The coolant 18 retained in the cooling pipe 22 can ensure that the temperature-conducting sleeve 23 cools the milling tank 15 and prevents the excessive temperature in the milling tank 15 from affecting the loss of nutrients in the grains.

[0055] The method of using the cryogenic mill with intelligent temperature control comprises the following steps:

[0056] Step 1: dump the material from the feed port 6 and store it in the storage bin 5. When the sealing cover 8 is in the open state, the material enters the grinding tank 15 through the discharge pipe 7.

[0057] Step 2: Start the hydraulic press 9 to drive the telescopic rod 10 to extend and retract, and when the support frame 11 is lowered, the drive motor 12 and the grinding block 13 are driven to descend and contact the grinding groove 15, and the drive motor 12 is started to drive the grinding block 13 to rotate to perform grinding work;

[0058] Step 3: When the support frame 11 descends, the limiting rod 14 is driven to descend and touch the upper edge of the sealing cover 8, so that the sealing cover 8 can be pushed to a horizontal position, and the bottom of the discharge pipe 7 is closed to prevent the material from continuing to be discharged;

[0059] Step 4: When the temperature inside the mill housing 1 is too high, the temperature sensor 19 transmits a signal to start the first pump 20 and the second pump 25, and the coolant 18 is input to the cooling pipe 22 through the liquid outlet pipe 21 to provide low temperature treatment for the temperature guide sleeve 23. At the same time, the coolant 18 in the cooling pipe 22 is discharged back to the cooling box 3 through the right liquid inlet pipe 24 to provide a circulating use of the coolant 18;

[0060] Step 5: The ground materials enter the material collecting box 17, and the material collecting box 17 can be taken out by opening the sliding door 2.

[0061] By setting the discharge limit, the load of the grinding block 13 due to excessive material in the grinding trough 15 is prevented from increasing. When the grinding block 13 effectively grinds the grinding trough 15, the sealing cover 8 is linked to control the material at the bottom of the discharge pipe 7, and the temperature is effectively controlled to prevent the internal temperature of the mill from rising. At the same time, the temperature is intelligently controlled through monitoring by the temperature sensor 19, and the coolant 18 is recycled according to the temperature change. The mill is intelligently controlled at low temperature, which has the effect of energy saving and environmental protection, and at the same time prevents the loss of nutrients in grains during the grinding process.
