Description

Technical Field

[0001] The present application relates to the technical field of stir-frying equipment, and in particular to a raw material stir-frying device for rapeseed oil production. Background Art

[0002] Rapeseed oil, commonly known as rapeseed oil, is a kind of edible oil squeezed from rapeseed. When producing rapeseed oil, it is necessary to use a stir-frying device to stir-fry the rapeseed at high temperature, which can condense many fine drops of oil in the cells of the rapeseed into large drops of oil, so that the rapeseed can fully produce oil and improve the effect of subsequent oil extraction. After retrieval, the patent document with the authorization announcement number CN211926445U announced a drying device for stir-frying rapeseed, including a stir-frying shell, a stir-frying cavity is provided inside the stir-frying shell, a plurality of air holes are provided on the top of the stir-frying cavity, a vertical cylinder is vertically provided in the stir-frying cavity, the two ends of the vertical cylinder are open, and rapeseed channels are left between the two ends of the vertical cylinder and the wall of the stir-frying cavity; the vertical cylinder is also adapted to be equipped with a spiral blade, and the spiral blade is rotatably connected to the stir-frying shell; the spiral blade is driven by a rotary driver to rotate around the axis of the vertical cylinder, and the rapeseed in the stir-frying shell is moved up and down by the rotation of the spiral blade, so as to stir the rapeseed, and the water vapor generated by heating is discharged from the air hole. Therefore, it can ensure that the rapeseed can be heated evenly, preventing the rapeseed from being burnt, thereby ensuring the quality of the finished rapeseed oil.

[0003] In actual use, it was found that the above-mentioned related scheme still has at least the following shortcomings: when the rapeseed is stir-fried in the process of controlling the up and down circulation movement in the stir-fry shell, the rapeseed falls at a relatively fast speed in the process of being discharged from the top of the vertical cylinder and falling downward, and the speed of the rapeseed falling from top to bottom cannot be effectively slowed down, resulting in the rapeseed piling up on the bottom inner wall of the stir-fry shell for a relatively long time, and the amount of rapeseed piling up on the bottom inner wall of the stir-fry shell is still relatively large, which can easily cause the rapeseed to be not heated comprehensively and evenly, resulting in low stir-frying efficiency.

An annular electric heating plate 8 is fixedly mounted on the outer wall of the heat-conducting stir-frying cylinder 2. The heat generated by the annular electric heating plate 8 can be transferred to the inner space of the heat-conducting stir-frying cylinder 2 through the power supply, so that the rapeseed can be heated. The outer insulation cylinder 1 can effectively reduce the heat generated by the annular electric heating plate 8 from being transferred to the external air, thereby reducing heat loss. The outer insulation cylinder 1 is provided with a feeding assembly for controlling the rapeseed to move from bottom to top in the heat-conducting stir-frying cylinder 2. The feeding assembly includes a plurality of heat-conducting support columns 9, a heat-conducting feeding cylinder 10, a spiral feeding shaft 11 and a motor 12. The top and bottom of the heat-conducting feeding cylinder 10 are both open. The structure is that the heat-conductive feeding cylinder 10 is vertically arranged in the heat-conductive stir-fry cylinder 2, one end of each of the heat-conductive supporting columns 9 is fixedly connected to the outer wall of the heat-conductive feeding cylinder 10, and the other end of each of the heat-conductive supporting columns 9 is fixedly connected to the inner wall of the heat-conductive stir-fry cylinder 2, and the heat-conductive supporting columns 9 are evenly distributed, and the spiral feeding shaft 11 is rotatably installed in the heat-conductive stir-fry cylinder 2, the bottom end of the spiral feeding shaft 11 passes through the heat-conductive feeding cylinder 10, and the top end of the spiral feeding shaft 11 extends to the outside of the heat-conductive stir-fry cylinder 2, and the motor 12 is fixedly installed on the top of the outer insulation cylinder 1, and the output shaft end of the motor 12 extends into the outer insulation cylinder 1 and is connected to the top end of the spiral feeding shaft 11 Fixedly connected, the heat-conductive stir-frying cylinder 2, the heat-conductive supporting column 9 and the heat-conductive feeding cylinder 10 are all made of steel. The use of multiple heat-conductive supporting columns 9 can not only stably support the heat-conductive feeding cylinder 10, but also transfer part of the heat generated by the annular electric heating plate 8 to the heat-conductive feeding cylinder 10. The motor 12 can control the rotation of the spiral feeding shaft 11. The rotation of the spiral feeding shaft 11 can transport the rapeseed from bottom to top in the heat-conductive feeding cylinder 10, so that the heat on the heat-conductive feeding cylinder 10 is transferred to the rapeseed, and then the rapeseed inside can be evenly heated, thereby improving the uniformity of heating the rapeseed and improving the efficiency of heating and stir-frying the rapeseed.

[0029] In this embodiment, a material blocking assembly 13 for slowing down the falling speed of rapeseed is provided in the heat-conductive stir-frying cylinder 2. The number of the material blocking assemblies 13 is set to be multiple, and the multiple material blocking assemblies 13 are all arranged on the outer wall of the heat-conductive feeding cylinder 10 and are evenly distributed. The material blocking assembly 13 includes an axle seat 131, a rotating shaft 132 and three blocking pieces 133. The axle seat 131 is fixedly mounted on the outer wall of the heat-conductive feeding cylinder 10, and the rotating shaft 132 is rotatably mounted on the axle seat 131. The three blocking pieces 133 are all fixedly mounted on the rotating shaft 132 and are distributed in an equidistant ring shape. In the process of rapeseed falling from top to bottom inside the heat-conductive stir-frying cylinder 2, the impact force generated by the rapeseed falling on the blocking piece 133 can push the blocking piece 133 and the rotating shaft 132 to rotate, that is, the falling speed of the rapeseed can be slowed down, and the falling direction of the rapeseed can be changed, so as to achieve the effect of further stir-frying the rapeseed, and further improve the heating uniformity of the rapeseed.

[0030] In this embodiment, a truncated cone-shaped material guide cover 14 is fixedly installed on the top of the thermal conductive material conveying barrel 10. The diameter of the truncated cone-shaped material guide cover 14 increases from top to bottom. The truncated cone-shaped material guide cover 14 can be used to guide the falling direction of the rapeseed, so that the rapeseed discharged from the top of the thermal conductive material conveying barrel 10 can slide smoothly along the outer wall of the truncated cone-shaped material guide cover 14.

[0031] In this embodiment, an automatic pressure relief valve 15 is fixedly installed on the end cover 5, and the automatic pressure relief valve 15 is connected to the inside of the feeding pipe 4. When the air pressure in the thermal conductive feeding barrel 10 is too high, the automatic pressure relief valve 15 can automatically relieve the pressure inside the thermal conductive feeding barrel 10, thereby achieving the effect of safe stir-frying operation.

[0032] In this embodiment, three supporting legs 3 distributed in a ring with equal intervals are fixedly installed on the bottom of the outer thermal insulation tube 1 to stably support the outer thermal insulation tube 1 .

[0033] In this embodiment, a support pad 16 is fixedly installed on the inner wall of the bottom of the outer insulation tube 1, and the bottom of the heat-conducting stir-fry tube 2 is fixedly connected to the top of the support pad 16, thereby improving the stability of the heat-conducting stir-fry tube 2 when it is installed and fixed in the outer insulation tube 1.

[0034] In this embodiment, in order to enable the rapeseed to be smoothly piled up in the central part of the bottom inner wall of the heat-conductive stir-fry tube 2 and to better control the rapeseed to be transported from bottom to top, the bottom of the heat-conductive stir-fry tube 2 is an arc-shaped concave surface structure, and the top of the plug 7 is an arc-shaped concave surface structure, and the top of the plug 7 is adapted to the bottom inner wall of the heat-conductive stir-fry tube 2.

[0035] In this embodiment, the annular electric heating plate 8 and the motor 12 can be purchased on the market. The wiring method and control method of the annular electric heating plate 8 and the motor 12 are mature technologies in the field and are fully disclosed, so they will not be described in detail in this article.

[0036] Through the above structure, the raw material stir-frying device for rapeseed oil production provided by the present application can control the rapeseed to be circulated and transported from bottom to top in the heat-conducting stir-frying cylinder 2 when in use, and can effectively slow down the speed at which the rapeseed falls from top to bottom after being discharged from the top of the heat-conducting feeding cylinder 10, thereby improving the comprehensiveness and uniformity of the heating of the rapeseed, and improving the efficiency of heating and stir-frying the rapeseed. During the specific operation, unscrew the end cover 5, pour an appropriate amount of rapeseed from the feeding pipe 4 into the heat-conducting stir-frying cylinder 2, and then tighten the end cover 5 to the top of the feeding pipe 4, and turn on the annular electric heating plate 8 to operate, so that the heat generated by the annular electric heating plate 8 can be transferred to the heat-conducting stir-frying cylinder 2, and And part of the heat on the heat-conductive stir-frying cylinder 2 can be transferred to the heat-conductive feeding cylinder 10 through multiple heat-conductive supporting columns 9, so as to heat the rapeseed. By controlling the operation of the motor 12, the motor 12 drives the spiral feeding shaft 11 to rotate. By utilizing the rotation of the spiral feeding shaft 11, the rapeseed on the inner wall of the bottom of the heat-conductive stir-frying cylinder 2 can be controlled to move vertically from bottom to top in the heat-conductive feeding cylinder 10, so that the rapeseed is discharged from the top of the heat-conductive feeding cylinder 10 and slides down from top to bottom along the outer inclined surface of the truncated cone-shaped material guide cover 14. Then, under the continuous operation of the motor 12, the rapeseed can be controlled to be circulated and transported from bottom to top in the heat-conductive stir-frying cylinder 2, so as to achieve the function of stir-frying the rapeseed.

[0037] After the rapeseed is discharged from the top of the heat-conducting feeding cylinder 10 and falls from top to bottom, the rapeseed will fall on the baffle 133. The impact force generated by the rapeseed falling on the baffle 133 can be used to push the baffle 133 and the rotating shaft 132 to rotate, thereby slowing down the falling speed of the rapeseed, so that the rapeseed in the falling process can be in contact with the heat inside the heat-conducting stir-fry cylinder 2 for a longer time, reducing the time and amount of rapeseed accumulation on the inner wall at the bottom of the heat-conducting stir-fry cylinder 2, and changing the falling direction of the rapeseed to achieve the effect of further stir-frying the rapeseed, thereby further improving the uniformity of heating the rapeseed and improving the efficiency of heating and stir-frying the rapeseed;

[0038] After the rapeseed is stir-fried, the motor 12 and the annular electric heating plate 8 are turned off, the plug 7 is unscrewed, and the rapeseed can be discharged from the discharge pipe 6.
