Description

Technical Field

[0001] This utility model relates to the field of peanut oil processing technology, specifically to a peanut oil dehydration device. Background Technology

[0002] Peanut oil is an edible vegetable oil extracted and refined from peanuts. It is pale yellow and transparent, with a clear color and a fragrant aroma. It is rich in a variety of nutrients, such as unsaturated fatty acids, which help lower cholesterol and protect cardiovascular health. It also contains antioxidants such as vitamin E, which can delay cell aging and enhance immunity. It is one of the high-quality cooking oils commonly used in family kitchens.

[0003] Freshly pressed peanut oil often contains a certain amount of water. This water not only affects the quality and storage stability of peanut oil, but may also provide conditions for the growth of microorganisms, leading to rancidity and deterioration of peanut oil, shortening its shelf life and reducing its food safety. Therefore, it is necessary to use a dehydration device to remove the water from peanut oil.

[0004] When dehydrating peanut oil, heating is usually used to evaporate the water. However, when the dehydrated peanut oil is discharged, it adheres to the inner wall of the device due to its adhesive properties, which slows down its flow and reduces the discharge efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a peanut oil dehydration device that effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A peanut oil dehydration device includes a heating cylinder. A hollow stirring shaft is mounted inside the heating cylinder via a drive mechanism, and stirring blades are provided on the outer surface of the hollow stirring shaft. A first threaded rod is rotatably mounted inside the hollow stirring shaft, and a nut is mounted on the outer surface of the first threaded rod. Multiple connecting slots are formed along the height of the outer surface of the hollow stirring shaft, and these slots are staggered with the stirring blades. Multiple connecting rods are mounted on the outer surface of the nut, and the ends of these connecting rods extend through the connecting slots to the outside of the hollow stirring shaft and are collectively fitted with a scraper ring. An L-shaped bracket is mounted on the top of the heating cylinder. The upper end of the first threaded rod extends through to the top of the hollow stirring shaft and is located below the horizontal plate of the L-shaped bracket. A bidirectional locking mechanism is provided on the outer surface of the first threaded rod, which can lock the first threaded rod to both the hollow stirring shaft and the L-shaped bracket.

[0008] Therefore, the hollow stirring shaft is driven to rotate by the drive mechanism, which in turn drives the stirring blades to stir the peanut oil, making it heat more evenly and improving the dehydration efficiency. The first threaded rod is kept fixed by the bidirectional locking mechanism. When the drive mechanism drives the hollow stirring shaft to rotate, the scraper ring can be raised and lowered under the action of the threaded connection to scrape off the peanut oil adhering to the inner wall of the heating cylinder, thus achieving the purpose of rapid oil discharge.

[0009] Furthermore, the drive mechanism includes a drive motor mounted on the upper surface of the heating cylinder, and a first pulley is mounted on the end of the output shaft of the drive motor. A second pulley is mounted on the outer surface of the hollow stirring shaft, and a transmission belt is fitted onto the outer surfaces of the second pulley and the first pulley.

[0010] Furthermore, the bidirectional locking mechanism includes two fixing blocks installed on the outer surface of the first threaded rod, and a second threaded rod is installed on the common internal thread of the two fixing blocks. Friction blocks are installed at both the upper and lower ends of the second threaded rod.

[0011] Furthermore, a vacuum pump is installed on the top of the heating cylinder. The pump's suction end is connected to the heating cylinder through a suction pipe, and the pump's outlet end is connected to the condenser through an outlet pipe.

[0012] Furthermore, an oil inlet pipe is installed on the outer surface of the heating cylinder, and an oil outlet pipe is installed at the bottom of the heating cylinder. Valves are installed inside both the oil inlet pipe and the oil outlet pipe.

[0013] Furthermore, a clearance groove is provided on the inner wall of the heating cylinder near its upper side. When the scraper ring rises to its highest position, it corresponds to the clearance groove.

[0014] Furthermore, a torsion bar is provided on the outer surface of the second threaded rod and located between the two fixed blocks.

[0015] Furthermore, a control panel is provided on the outer surface of the heating cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] 1. This utility model drives the hollow stirring shaft to rotate through a drive mechanism, which in turn drives the stirring blades to stir the peanut oil, making it heat more evenly and improving the dehydration efficiency. Furthermore, the first threaded rod is kept fixed through a bidirectional locking mechanism. When the drive mechanism drives the hollow stirring shaft to rotate, the scraper ring can be raised and lowered under the action of the threaded connection to scrape off the peanut oil adhering to the inner wall of the heating cylinder, thereby achieving the purpose of rapid oil discharge.

[0018] 2. By setting the relief groove, the scraper ring does not contact the inner wall of the heating cylinder when it is at the height of the corresponding relief groove. This avoids the scraper ring from rubbing against the inner wall of the heating cylinder for a long time when the hollow stirring shaft drives the scraper ring to rotate, thus preventing wear and noise problems.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This utility model provides a peanut oil dehydration device, including a heating cylinder 1. A hollow stirring shaft 101 is installed inside the heating cylinder 1 via a drive mechanism 2. Stirring blades 102 are provided on the outer surface of the hollow stirring shaft 101. A first threaded rod 103 is rotatably installed inside the hollow stirring shaft 101. A nut 104 is installed on the outer surface of the first threaded rod 103. Multiple connecting slots 105 are opened along the height direction on the outer surface of the hollow stirring shaft 101, and the connecting slots 105 and the stirring blades 102 are staggered. Multiple connecting rods 106 are installed on the outer surface of the nut 104. The ends of the multiple connecting rods 106 extend through the connecting slots 105 to the outside of the hollow stirring shaft 101 and are collectively equipped with scraper rings 107. An L-shaped bracket 108 is installed on the top of the heating cylinder 1. The upper end of the first threaded rod 103 extends through to the top of the hollow stirring shaft 101 and is located below the horizontal plate of the L-shaped bracket 108. A bidirectional locking mechanism 3 is provided on the outer surface of the first threaded rod 103. The bidirectional locking mechanism 3 can lock the first threaded rod 103 together with the hollow stirring shaft 101 and the L-shaped bracket 108 respectively.

[0023] In use, the peanut oil is heated by the heating cylinder 1, and the hollow stirring shaft 101 is driven to rotate by the driving mechanism 2, which drives the stirring blade 102 to stir the peanut oil, making it more evenly heated and improving the dehydration efficiency.

[0024] The first threaded rod 103 and the hollow stirring shaft 101 are locked together by the bidirectional locking mechanism 3, which allows the hollow stirring shaft 101 to drive the scraper ring 107 to rotate together. When oil drainage is required, the first threaded rod 103 can be locked together with the L-shaped bracket 108 by the bidirectional locking mechanism 3. At this time, the hollow stirring shaft 101 is driven to rotate by the drive mechanism 2, and the first threaded rod 103 remains fixed. The hollow stirring shaft 101 drives the nut 104 to rotate on the surface of the first threaded rod 103. Therefore, under the action of the threaded connection, the nut 104 can be raised and lowered along the height direction of the first threaded rod 103, and the scraper ring 107 can be raised and lowered through the connecting rod 106 to achieve the purpose of scraping oil, thereby enabling the peanut oil to be drained quickly and reducing the residue on the inner wall of the heating cylinder 1.

[0025] Preferably, the drive mechanism 2 includes a drive motor 201 mounted on the upper surface of the heating cylinder 1, and a first pulley 202 is mounted on the end of the output shaft of the drive motor 201. A second pulley 203 is mounted on the outer surface of the hollow stirring shaft 101, and a transmission belt 204 is fitted onto the outer surfaces of the second pulley 203 and the first pulley 202.

[0026] When the drive motor 201 is started, it drives the first pulley 202 to rotate. Under the transmission action of the transmission belt 204, the hollow stirring shaft 101 can be driven to rotate.

[0027] Preferably, the bidirectional locking mechanism 3 includes two fixing blocks 301 installed on the outer surface of the first threaded rod 103, and a second threaded rod 302 is installed inside the two fixing blocks 301 with a common thread. Friction blocks 303 are installed at both the upper and lower ends of the second threaded rod 302.

[0028] When the second threaded rod 302 is rotated, it can be raised and lowered under the action of the threaded connection. When the second threaded rod 302 descends, it causes the friction block 303 at the bottom to press against the top of the hollow stirring shaft 101, thereby locking the first threaded rod 103 and the hollow stirring shaft 101 together. When the second threaded rod 302 rises, it causes the friction block 303 at the top to contact the horizontal plate of the L-shaped bracket 108, and causes the friction block 303 at the bottom to separate from the hollow stirring shaft 101, thereby locking the hollow stirring shaft 101 and the L-shaped bracket 108 together.

[0029] Preferably, a vacuum pump 4 is installed on the top of the heating cylinder 1. The suction end of the vacuum pump 4 is connected to the heating cylinder 1 through a suction pipe 401, and the outlet end of the vacuum pump 4 is connected to the condenser 403 through an outlet pipe 402.

[0030] The water vapor evaporated in the heating cylinder 1 is extracted by the vacuum pump 4 and transported to the condenser 403 through the gas outlet pipe 402. After condensation, the water vapor is liquefied and then discharged to the outside.

[0031] Preferably, an oil inlet pipe 109 is installed on the outer surface of the heating cylinder 1, and an oil outlet pipe 110 is installed at the bottom of the heating cylinder 1. Valves are provided inside both the oil inlet pipe 109 and the oil outlet pipe 110.

[0032] Peanut oil is added to heating cylinder 1 through oil inlet pipe 109 for dehydration treatment. After the treatment is completed, the valve on oil outlet pipe 110 is opened to discharge the peanut oil.

[0033] Preferably, the heating cylinder 1 has a relief groove 6 on its inner wall near its upper side. When the scraper ring 107 rises to its highest position, it corresponds to the relief groove 6.

[0034] By setting the relief groove 6, when the scraper ring 107 is at the height of the corresponding relief groove 6, the scraper ring 107 does not contact the inner wall of the heating cylinder 1, thereby avoiding the scraper ring 107 from rubbing against the inner wall of the heating cylinder 1 for a long time when the hollow stirring shaft 101 drives the scraper ring 107 to rotate, which would cause wear and noise problems.

[0035] Preferably, a torsion bar 304 is provided on the outer surface of the second threaded rod 302 and located between the two fixing blocks 301.

[0036] The torsion bar 304 provides a point of force, which can better rotate the second threaded rod 302 and apply sufficient torque to ensure that the two friction blocks 303 are pressed against the hollow stirring shaft 101 and the L-shaped bracket 108 respectively.

[0037] Preferably, a control panel 5 is provided on the outer surface of the heating cylinder 1.

[0038] Control panel 5 allows for unified control and adjustment of all electrical equipment, ensuring stable operation of the device.
