Description

Technical Field

[0001] This invention belongs to the field of rapeseed oil production technology, specifically relating to a rapeseed oil pressing and extraction device. Background Technology

[0002] In the edible oil industry, rapeseed oil, as a common and important type of oil, has always received considerable attention for its quality and yield. Traditional rapeseed oil pressing extraction methods often have limitations, resulting in less than ideal oil yields and affecting the production efficiency and economic benefits of rapeseed oil.

[0003] In the past, rapeseed oil pressing processes typically involved simply feeding rapeseed directly into the pressing equipment without adequate pretreatment. Due to differences in the size, shape, and structure of rapeseed, some larger rapeseed particles did not have sufficient contact with the screw press during the pressing process, making it difficult to completely extract the oil from the cells and thus limiting the increase in oil yield.

[0004] In addition, the temperature of rapeseed also has a significant impact on oil extraction. Without preheating, the cell structure of rapeseed is relatively compact, resulting in poor oil flow. This increases the difficulty of separating oil from the cells, leading to insufficient oil release during pressing and further reducing the oil yield.

[0005] Meanwhile, traditional pressing equipment is relatively simple in function and cannot simultaneously heat and refine rapeseed. Furthermore, heating or crushing alone often fails to achieve optimal pressing results, necessitating a comprehensive pretreatment method to improve rapeseed pressing conditions.

[0006] To address this, we propose a rapeseed oil pressing and extraction device. This device pre-treats rapeseed by heating and grinding, making the rapeseed cell structure easier to break down and the oil easier to press out, thus significantly improving the oil yield. Utility Model Content

[0007] The purpose of this invention is to provide a rapeseed oil pressing and extraction device. This device pre-treats rapeseed by heating and grinding, making the cell structure of the rapeseed easier to break down and the oil easier to press out, thus significantly improving the oil yield.

[0008] The specific technical solution adopted in this utility model is as follows:

[0009] A rapeseed oil pressing and extraction device includes two support plates, a cylinder is fixedly arranged between the two support plates, a screw press is arranged inside the cylinder, a feed shell is fixedly arranged on the outside of the cylinder and communicates with it, and a pretreatment component is arranged inside the feed shell.

[0010] The pretreatment component includes a heat-conducting pipe connected to the inner wall of the feed housing. A mounting groove is provided at the center of the top of the heat-conducting pipe, and a heating pipe is provided inside the mounting groove. A conical distributing plate is connected to the top of the heat-conducting pipe. A guide hole is arrayed on the heat-conducting pipe, and a telescopic component is provided at the bottom of the heat-conducting pipe. Multiple connecting rods are provided on the telescopic component, and a grinding roller located inside the guide hole is installed on each connecting rod.

[0011] Furthermore, a flow gap is provided between the outer side of the grinding roller and the inner wall of the feed guide hole.

[0012] Furthermore, an abrasive layer is provided on the outer side of the abrasive roller.

[0013] Furthermore, an oil outlet is provided on the outer side of the cylinder, and an oil receiving tray is provided between the two support plates.

[0014] Furthermore, a filter screen is provided at the outlet of the oil receiving tray.

[0015] Furthermore, the telescopic assembly includes an electrically operated telescopic rod disposed at the center of the bottom of the heat-conducting pipe, the telescopic end of which is connected to the connecting rod.

[0016] The technical effects achieved by this utility model are as follows:

[0017] First, the screened rapeseed is placed into the feeding shell, and the heating element is activated simultaneously. The heating element generates heat, which is transferred to the heat-conducting pipe, heating the entire pipe. The incoming rapeseed is then diverted by a conical distribution plate and enters the feed inlet. As the rapeseed flows through the feed inlet, it absorbs heat, facilitating subsequent oil extraction. Simultaneously, the telescopic component activates, driving the connecting rod to move the grinding roller inside the feed inlet, breaking larger rapeseed particles into smaller ones. This increases the contact area between the rapeseed and the screw press during pressing, further improving the oil yield. This device, through pre-treatment of the rapeseed with heating and grinding, makes the rapeseed's cell structure easier to break down, allowing for easier oil extraction and significantly increasing the oil yield.

[0024] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, the specific technical solution adopted by this utility model is as follows: a rapeseed oil pressing and extraction device includes two support plates 1, a cylinder 2 is fixedly arranged between the two support plates 1, a pressing screw 3 is arranged inside the cylinder 2, a feeding shell 4 connected to the cylinder 2 is fixedly arranged outside the cylinder 2, and a pretreatment component is arranged inside the feeding shell 4.

[0026] The pretreatment component includes a heat-conducting pipe 5 connected to the inner wall of the feed housing 4. A mounting groove 6 is provided at the center of the top of the heat-conducting pipe 5. A heating pipe 7 is installed inside the mounting groove 6. A conical distributing plate 8 is connected to the top of the heat-conducting pipe 5. A guide hole 9 is arrayed on the heat-conducting pipe 5. A telescopic component is provided at the bottom of the heat-conducting pipe 5. Multiple connecting rods 10 are provided on the telescopic component. A grinding roller 11 located inside the guide hole 9 is installed on each connecting rod 10.

[0027] A flow gap is provided between the outer side of the grinding roller 11 and the inner wall of the feed hole 9, through which rapeseed can flow out.

[0028] Meanwhile, an abrasive layer is provided on the outer side of the abrasive roller 11. The abrasive layer is granular and made of silicon carbide, which has a very good abrasive effect.

[0029] The screw press 3 is equipped with a motor connected to the support plate 1. The motor drives the screw press 3 to rotate, thereby pressing oil.

[0030] It should be noted that the motor, screw 3, and cylinder 2 are all existing technologies in screw oil presses. The working principle and discharge structure of screw 3 are not shown in the diagram, but they are existing technologies and will not be elaborated on here.

[0031] An oil outlet 13 is provided on the outside of the cylinder 2, and an oil receiving plate 12 is provided between the two support plates 1. The extracted rapeseed oil falls through the oil outlet 13 onto the oil receiving plate 12 and is then collected.

[0032] Furthermore, the oil receiving tray 12 is equipped with a filter screen 14 at its discharge port, through which the rapeseed oil is filtered to obtain high-quality rapeseed oil.

[0033] The telescopic assembly includes an electric telescopic rod 15 located at the center of the bottom of the heat-conducting pipe 5. The telescopic end of the electric telescopic rod 15 is connected to the connecting rod 10, and the connecting rod 10 is moved up and down by the electric telescopic rod 15.

[0034] The heat pipe 5 and the inner wall of the feed hole 9 are connected in a detachable manner, such as by bolt fixing or snap-fit, to achieve the effect of easy installation and disassembly. The heat pipe 5 can be made of ceramic or other materials, which have the effect of rapid heat conduction.

[0035] It should be noted that the temperature of heating element 7 can be controlled, for example, through a temperature controller. The connection method between heating element 7 and temperature controller is existing technology and will not be elaborated here.

[0036] The working principle of this device is as follows: First, the screened rapeseed is placed into the feed housing 4, and the heating tube 7 is activated simultaneously. The heating tube 7 generates heat, which is transferred to the heat conduction tube 5, making the entire heat conduction tube 5 heated. Then, the rapeseed enters through the conical distribution plate 8, where it is diverted and flows into the guide hole 9. As the rapeseed flows into the guide hole 9, it absorbs heat, making it more resistant to oil extraction. Simultaneously, the telescopic component is activated, driving the connecting rod 10 to move the grinding roller 11 inside the guide hole 9, breaking larger rapeseed particles into smaller ones. This increases the contact area between the rapeseed and the screw press 3 during pressing, further improving the oil yield. This device, through pretreatment of heating and grinding the rapeseed, makes the cell structure of the rapeseed easier to break down, making it easier to extract the oil and significantly improving the oil yield.
