Description
Technical Field
[0001] The invention relates to the technical field of rapeseed processing, in particular to a rapeseed steaming and frying method and steaming and frying equipment. Background Art
[0002] Rapeseed, also known as Brassica rapa, is the seed of the cruciferous crop rapeseed. Rapeseed has long pods, many pods, and plump seeds. It is one of China's major oil crops and nectar crops. Its seeds are one of the main raw materials for making oils. Before oil is extracted from rapeseed, it is usually necessary to stir-fry the rapeseed to increase the temperature and reduce the water content of the rapeseed, thereby improving the quality of the oil. However, the energy-saving rapeseed steaming and frying pot with patent number CN222099882U includes: a pot body, an accommodating cavity inside the pot body, a first partition and a second partition arranged from top to bottom in the accommodating cavity, the first partition and the second partition dividing the accommodating cavity from top to bottom into a steaming layer, a frying layer and a heat preservation layer, the water vapor generated by the rapeseed in the frying layer during the heating process can heat the rapeseed in the steaming layer, the rapeseed in the steaming layer is heated under the combined action of the water vapor and the heating device, and the rapeseed in the steaming layer absorbs moisture after being fully in contact with the water vapor, so that the moisture content of the rapeseed in the steaming layer can be increased from 10% to 20%-30%; However, when this technical solution is in operation, the rapeseed is heated by combining the electric heating tube with the heat transfer oil. However, the heat transfer oil needs to be preheated to the working temperature to effectively transfer heat, and the startup time is relatively long. Moreover, under the same heating requirements, the heat transfer oil system requires a higher power input due to heat loss, resulting in increased energy consumption costs and a larger overall energy consumption. At the same time, the heat transfer oil may decompose and produce carbon deposits at high temperatures, blocking the oil circuit or covering the surface of the heating tube, affecting the heat transfer efficiency and shortening the life of the equipment.

[0012] This technical solution also discloses a method for steaming and frying rapeseed, comprising the following steps: Step S1: First, prepare the rapeseed, screen and crush the rapeseed in advance, and then put the rapeseed into the pot through the feeding port; Step S2: After the rapeseed enters the inner wall of the pot, it will first enter the steaming layer, where the partition and the inner wall of the pot are embedded with electric heating layers.

Due to the high water content of the rapeseed, there is a large room for the rapeseed to fall. Before the rapeseed temperature reaches the required temperature, the rapeseed will basically not burn. This is beneficial to improving the frying quality of the rapeseed, shortening the heating time, and saving energy. The rapeseed temperature and water content can meet the preset requirements almost at the same time, which is more beneficial to improving the frying quality of the rapeseed, shortening the heating time, and saving energy. At the same time, the electric heating method heats evenly, further increasing the energy saving effect during the rapeseed steaming and frying process. Step S5: When the rapeseed enters the frying layer from the steaming layer, the temperature has reached 80 to 90 degrees Celsius, and the heating time is shortened by about half, which can save 50% to 60% of energy; Step S6: The rapeseed then enters the insulation layer, which can keep the rapeseed warm and prevent the rapeseed from cooling down and affecting the oil extraction effect. A heat dissipation port is provided on one side of the insulation layer. When the rapeseed in the insulation layer needs to dissipate heat, the baffle can be removed and the rapeseed can be cooled.
[0013] The present invention provides a method and equipment for steaming and frying rapeseed, which have the following beneficial effects: 1. Electric heating is used to evenly steam and stir-fry rapeseed. The existing thermal oil heating method suffers from high heat efficiency loss and a utilization rate of only 60% to 70%.

A lifting piece 16 is provided inside the socket, and an inclined plate 17 is provided on the lower side of the lifting piece 16. The upper side of the lifting plate is connected to the inner wall of the upper side of the assembly shell 13 through a spring rod 18; A heat dissipation port 19 is provided on one side of the pot body 1, a baffle 20 is provided at the heat dissipation port 19, a slot 21 corresponding to the baffle 20 is provided on the lower side of the heat dissipation port 19, a discharge port 22 is provided on the lower side of the pot body 1, and delivery pipes are evenly provided on both sides of the pot body 1. The delivery pipes are composed of a vertical pipe 24 and a pair of connectors 25. The pair of connectors 25 are connected to the steaming layer 6 and the frying layer 7 respectively; The blocking structure includes a sector block 26 that matches the sector through hole 10. A lifting ring 27 is provided on the lower side of the partition 5. The lifting ring 27 is sleeved on the outer side of the main shaft 4. A transmission frame 28 is provided on the lower side of the sector block 26. One side of the transmission frame 28 is connected to the lifting ring 27. The upper side of the transmission frame 28 is connected to the lower side of the sector block 26 through a vertical rod 29. A horizontal plate 30 is provided on the inner wall of the pot body 1, and an electric push rod 31 is provided on the upper side of the horizontal plate 30. The output end of the electric push rod 31 is connected to the upper side of the transmission frame 28; It should be noted that rapeseed is one of the main raw materials for making oils and fats. Before pressing the rapeseed, it is usually necessary to stir-fry the rapeseed to increase the temperature of the rapeseed and reduce the water content of the rapeseed to improve the quality of the oil. The operator first screens and cleans the rapeseed and crushes the rapeseed to facilitate the subsequent steaming and stir-frying of the rapeseed. Before steaming and frying, the operator can open the sealing cover 34 and feed the rapeseed material into the tube body through the feeding port and into the inner wall of the insulation layer 8. At this time, the electric push rod 31 is controlled to operate, and then the transmission frame 28 and the vertical rod 29 are cooperated to drive the lifting ring 27 and the fan-shaped block 26 to descend respectively, and the fan-shaped block 26 can be separated from the fan-shaped through-hole 10. At this time, the driving member 3 is controlled to operate, and the cross 12 and the components located on the lower side of the cross 12 can be driven to rotate through the main shaft 4, and the rapeseed inside the insulation layer 8 can be fed into the frying layer 7 through the fan-shaped through-hole 10. At this time, the driving member 3 continues to operate, and the cross 12 and other components are driven to rotate respectively through the main shaft 4. The motor heat layer can be used to evenly heat the rapeseed, thereby achieving the purpose of frying the rapeseed. The upper side of the fan-shaped block 26 is provided with an inclined chamfer to prevent rapeseed from accumulating on the fan-shaped block 26. Since the upper end surface of the fan-shaped block 26 is higher than the upper end surface of the partition 5 after the fan-shaped through hole 10 is plugged into the fan-shaped through hole 10, a spring rod 18 is provided inside the assembly shell 13. The lifting piece 16 and the inclined plate 17 located on the lower side of the lifting piece 16 can automatically rise after contacting the upper side of the fan-shaped block 26, so as not to interfere with the fan-shaped block 26. The spring rod 18 can always keep the inclined plate 17 inserted into the rapeseed material to ensure the stirring effect of the rapeseed. The assembly shell 13 is connected to the cross 12 by screws 14, which is convenient for replacing the assembly shell 13 and other components after the device is used. When the rapeseed enters the frying layer 7 for frying, the water vapor generated during the frying process will enter the steaming layer 6 through the vertical pipe 24 and the pair of connecting heads 25. After the rapeseed material in the steaming layer 6 is fully in contact with the water vapor, it will absorb water, so that the water content of the rapeseed material in the steaming layer 6 can be increased from 10% to 20%-30%. Then, when the rapeseed material in the steaming layer 6 enters the frying layer 7, the temperature of the rapeseed material is higher and the water content is higher. Within the same heating time, the temperature of the steamed rapeseed material can reach the preset temperature faster. Moreover, due to the high water content of the rapeseed material, it has a larger falling space. Before the rapeseed material temperature reaches the required temperature, the rapeseed material will basically not be burnt, which is beneficial to improving the frying quality of the rapeseed material, shortening the heating time, and saving energy. When the rapeseed enters the frying layer 7 from the steaming layer 6, the temperature has reached 80 to 90 degrees Celsius, the heating time is shortened by about half, and energy can be saved by 50% to 60%. In addition, since lecithin is hydrophilic, the rapeseed is steamed and fried after absorbing water, and the lecithin can fully contact with water. During the steaming and frying process, the lecithin can be dephosphorized, reducing the cost of oil refining and helping to improve the quality of the oil. The steaming process can also detoxify the rapeseed meal, thereby increasing its value. The rapeseed meal protein is less damaged, the solubility is increased by about 5%, and the application is wider and the value is higher. After the frying is completed, the electric push rod 31 located on the lower side of the partition 5 of the frying layer 7 is controlled to operate, thereby cooperating with the driving member 3, the main shaft 4, the cross 12 and the components located on the lower side of the cross 12 to send the rapeseed into the insulation layer 8 for insulation operation. When the rapeseed needs to be cooled, the ring 39 on the upper side of the baffle 20 can be connected to the hook 38, and the heat dissipation port 19 can be exposed, so that the rapeseed can be cooled. The transmission frame 28 is connected to the lower side of the partition 5 by a telescopic rod, which can increase the stability of the transmission frame 28. After the above operations are completed, the insert plate 40 can be opened and the steamed and fried rapeseed can be discharged through the discharge port 22.
[0028] Grooves 32 are provided on both sides of the sector block 26 , and protrusions 33 corresponding to the grooves 32 are provided on both sides of the sector block 26 , so as to facilitate limiting the position of the sector block 26 .
[0029] A sealing cover 34 is plugged into the feeding port, and a handle 35 is provided on the upper side of the sealing cover 34 to facilitate the operator to move the sealing cover 34.
[0030] A solenoid valve 36 is provided in the middle portion of the vertical pipe 24 , and an operator can control the on / off of the vertical pipe 24 through the solenoid valve 36 .
[0031] A control panel 37 is provided on the front side of the pot body 1 , and the control panel 37 is electrically connected to the driving member 3 , the electric push rod 31 , the motor thermal layer and the solenoid valve 36 , respectively, so as to facilitate the operator to control the above components.
[0032] A support base 41 is mounted on the lower side of the pot body 1 to increase the stability of the pot body 1; To sum up, the present technical solution uses electric heating to uniformly steam and fry the rapeseed, while the existing thermal oil heating method has high thermal efficiency loss and a utilization rate of only 60% to 70%. The present solution has low thermal efficiency loss and a thermal efficiency utilization rate of more than 95%. At the same time, the overall heating effect is uniform, the temperature control is simple, and it has the advantages of fast startup response speed, easy maintenance, and overall safety, thereby achieving energy-saving effects. At the same time, through the coordination of the stirring structure and the sealing structure, the rapeseed can be heated evenly, and with the cooperation of the conveying pipe and the baffle 20 and other components, the rapeseed steaming and frying effect can be further increased.
[0033] This technical solution also discloses a method for steaming and frying rapeseed, comprising the following steps: Step S1: First, prepare rapeseed, screen and clean the rapeseed and crush it in advance, and then put the rapeseed into the pot body 1 through the feeding port; Step S2: After the rapeseed enters the inner wall of the pot body 1, the rapeseed will first enter the steaming layer 6, wherein the partition 5 and the inner wall of the pot body 1 are both embedded with an electric heating layer 9. The operation of the motor heating layer can be controlled to uniformly heat every corner of the pot body 1. Compared with the existing technology using thermal oil, the method has the advantages of uniform heating, fast start-up response speed, and overall easy control; Step S3: Control the driving member 3 to operate, drive the multiple stirring structures to rotate via the main shaft 4, and stir the rapeseed in the steaming layer 6. At the same time, the blocking structure is opened, and the stirring structure can drive the rapeseed into the frying layer 7. Step S4: The electric heating layer 9 cooperates with the stirring structure to evenly fry the rapeseed. The water vapor generated during the frying process will enter the steaming layer 6 through multiple groups of conveying pipes (at least four groups). After the rapeseed in the steaming layer 6 is fully in contact with the water vapor, it will absorb water, so that the water content of the rapeseed in the steaming layer 6 can be increased from 10% to 20%-30%. When the rapeseed in the steaming layer 6 enters the frying layer 7, the temperature of the rapeseed is higher and the water content is higher. Within the same heating time, the temperature of the steamed rapeseed can reach the preset temperature faster. Due to the high water content of the rapeseed, there is a large room for temperature drop. Before the rapeseed temperature reaches the required temperature, the rapeseed will basically not burn. This is beneficial to improving the frying quality of the rapeseed, shortening the heating time, and saving energy. The temperature and water content of the rapeseed can meet the preset requirements almost at the same time, which is more beneficial to improving the frying quality of the rapeseed, shortening the heating time, and saving energy. At the same time, the electric heating method heats evenly, further increasing the energy saving effect during the rapeseed steaming and frying process. Step S5: When the rapeseed enters the frying layer 7 from the steaming layer 6, the temperature has reached 80 to 90 degrees Celsius, and the heating time is shortened by about half, which can save 50% to 60% of energy; Step S6: The rapeseed then enters the insulation layer 8, which can keep the rapeseed warm and prevent the rapeseed from cooling down and affecting the oil pressing effect. A heat dissipation port 19 is provided on one side of the insulation layer 8. When the rapeseed in the insulation layer 8 needs to dissipate heat, the baffle 20 can be removed and the rapeseed can be cooled.

The thermal insulation layer (8) can keep the rapeseed warm and prevent the rapeseed from cooling down and affecting the oil pressing effect. A heat dissipation port (19) is provided on one side of the thermal insulation layer (8). When the rapeseed in the thermal insulation layer (8) needs to dissipate heat, the baffle (20) can be removed and the rapeseed can be cooled.
