Description

Technical Field

[0001] The utility model belongs to the technical field of stone mills, and particularly relates to a stone mill cooling device for sesame paste production. Background Technique

[0002] During the production process of sesame paste, sesame needs to be ground, such as using a stone mill and other grinding equipment. For the existing stone mill equipment for grinding sesame, in order to maintain the taste of the ground sesame paste, the stone mill needs to be cooled. For example, the patent application number 202321984997.X discloses a cooling device for a stone mill for sesame, including a stone mill mechanism, a material storage frame, a fixed disk, a movable disk, etc. By setting the stone mill mechanism to provide the basic grinding function of the device, and by setting the heat dissipation mechanism to provide heat dissipation for the stone mill mechanism. Among them, the conduit, water pump, and water outlet pipe cooperate with the heat conduction frame to drive water to flow in the inner cavity of the heat conduction frame. At the same time, the heat conduction frame also absorbs heat from the stone mill mechanism, and is combined with the first fan for blowing and heat dissipation. And the circulating water can absorb heat and cool down under the cooperation of the circulation mechanism. In this way, through the blowing of the wind and the flow of water, the heat conduction frame continuously absorbs heat from the stone mill mechanism, thereby delaying the temperature rise during the grinding operation of the stone mill mechanism. Furthermore, the grinding efficiency of the stone mill mechanism can be improved according to the real-time temperature, thus improving the production speed of sesame paste.

[0003] Although the above disclosed cooling scheme can achieve the cooling of the lower disk, the scheme has the following defects: First, the cooling scheme is complex and requires more structures, resulting in a large size of the equipment and more occupied space. Second, although the cooling scheme uses blowing and water flow for cooling, the degree of cooling is limited, and the temperature of the lower disk can only be cooled to slightly lower than room temperature. In an environment where the overall room temperature is relatively high, it is inconvenient to ensure the low-temperature grinding effect of sesame paste. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides a stone mill cooling device for sesame paste production, which simplifies the cooling scheme, reduces the structures required for cooling, does not additionally increase the size, makes the equipment occupy less space, and moreover, can cool the lower grinding disk to a lower temperature, facilitating the lower grinding disk to be cooled to a temperature far lower than room temperature. In an environment where the overall room temperature is relatively high, the low-temperature grinding effect of sesame paste can still be ensured.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A stone mill cooling device for sesame paste production, including a lower grinding disc. A material frame is integrally formed at the bottom of the lower grinding disc.

[0010] Furthermore, heat-insulating cotton is fixedly connected to the bottom of the box body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. Through the cavity below the lower grinding disc, the structures of the box body, the thermoelectric cooling sheet and the copper sheet required for cooling the lower grinding disc, including the motor required for driving the upper grinding disc and the mounting plate structure for mounting the motor, are all located inside the cavity. Compared with the existing solutions, it simplifies the cooling solution, reduces the structures required for cooling, does not additionally increase the size, and makes the equipment occupy less space. Moreover, the copper sheet is used to conduct the low temperature generated by the thermoelectric cooling sheet to reduce the temperature of the cooling liquid, and the cooling liquid cools the upper part of the lower grinding disc. Compared with blowing and water flow, it can cool the lower grinding disc to a lower temperature, which is convenient for the lower grinding disc to be cooled to a temperature far lower than the room temperature. In an environment where the overall room temperature is relatively high, it can still ensure the low-temperature grinding effect of sesame paste.

[0013] 2. The sealed bearing facilitates the sealing effect at the connection between the output shaft of the motor and the box body during operation. The stirring blade facilitates the agitation of the coolant by the rotating stirring blade during the grinding process, so as to evenly cool the coolant. The support rod increases the supporting effect of the box body on the top of the lower grinding disc. The pipeline facilitates the replacement of the coolant to avoid the phenomenon of coolant deterioration due to long-term non-replacement. The heat dissipation fan facilitates the heat dissipation of the thermoelectric cooler to prevent the heating surface of the thermoelectric cooler from overheating. The heat-insulating cotton facilitates the protection of the temperature of the coolant in the box body, reduces the influence of the high indoor temperature on the coolant, and slows down the temperature rise of the coolant.

A copper sheet 13 is fixedly connected to the bottom of the box body 6. A thermoelectric cooling sheet 9 is fixedly connected to the bottom of the copper sheet 13. The upper side of the thermoelectric cooling sheet 9 is the refrigerating surface and is in contact with the copper sheet 13. A support rod 10 is fixedly connected to the bottom of the box body 6. The bottom end of the support rod 10 is fixedly connected to the installation plate 5. A pipeline 11 is communicated with the bottom of the box body 6.

[0021] Working principle: In the present utility model, the thermoelectric cooling sheet 9 is a semiconductor refrigeration sheet, which is a finished product device that can be directly purchased in the existing market. Its working principle is publicly known technology and will not be elaborated here. When grinding sesame paste, the motor 3 drives the upper grinding disc 4 to rotate. When sesame enters between the upper grinding disc 4 and the lower grinding disc 1 from the hopper above the upper grinding disc 4, the rotating upper grinding disc 4 grinds the sesame. The ground sesame paste falls into the material frame 2 and then is discharged. During the grinding process, when it is necessary to cool the top of the lower grinding disc 1, the thermoelectric cooling sheet 9 is started. The upper side of the thermoelectric cooling sheet 9 generates low temperature, and the temperature is conducted by the copper sheet 13 to cool the cooling liquid in the box body 6. The cooling liquid can be water or oil. The stirring blade 8 rotates synchronously with the motor 3 to stir the cooling liquid, so that the cooling liquid is evenly cooled. The cooled cooling liquid cools the top of the lower grinding disc 1, and the heat dissipation fan 12 is turned on to dissipate heat from the heating area on the lower side of the thermoelectric cooling sheet 9. The heat insulating cotton 14 isolates the hot air from being conducted to the box body 6, so as to maintain the low temperature effect of the cooling liquid. Until the temperature of the cooling liquid drops to a certain temperature, this temperature standard is that it can effectively cool the top of the lower grinding disc 1, then the thermoelectric cooling sheet 9 can be turned off. When the lower grinding disc 1 has a tendency to heat up again, it can be cooled in the same way as above.
