Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camellia oil refining, in particular to a camellia oil refining cooling device. BACKGROUND

[0002] In the camellia oil refining process system, after degumming, deacidification, bleaching and deodorization, the camellia oil has removed most of the impurities, odors and harmful components, but still contains wax (melting point 40-50℃) and high melting point glycerides (such as saturated fatty acid glycerides), which are dissolved in oil at room temperature. Once in a low temperature environment, fine crystals will be precipitated due to the decrease in solubility, resulting in turbidity of the oil and reduction of transparency.

[0003] In the traditional winterization cooling process, the crystallization amount of wax and high melting point glycerides increases significantly. As the crystals gradually form and grow, the surface will adsorb trace impurities in the oil due to intermolecular forces, forming crystals with strong viscosity. These crystals are easily attached to the inner wall of the cooling equipment and the stirring frame, and gradually accumulate to form dense wax scale.

[0004] The accumulation of wax scale on the inner wall of the equipment and the stirring frame for a long time will affect the heat transfer efficiency. The wax scale on the inner wall of the cooling equipment will form an insulating layer, resulting in uneven oil temperature distribution in the tank, making it difficult to control the winterization cooling rate, affecting the quality stability of the oil, and increasing the cleaning difficulty and cost.

[0005] Therefore, there is an urgent need for a camellia oil refining cooling device that can filter crystals. SUMMARY

[0019] The camellia oil refining and cooling device provided by the present application can collect the crystals precipitated during cooling, reduce the adhesion of the crystals on the inner wall of the inner cylinder or the stirring part, and reduce the filtering difficulty. The camellia oil to be cooled is injected into the inner cylinder, the cooling mechanism is started, the oil temperature in the inner cylinder is reduced by the cooling medium, and the stirring mechanism is started synchronously. The oil is uniformly cooled by low-speed rotation. As the oil temperature gradually decreases, the wax and oil ester in the camellia oil begin to precipitate crystals.

If the stirring mechanism rotates counterclockwise, the sliding tube slides in the opposite direction, and the flip cover mechanism controls the opening and closing states of the intercepting nets in the opposite direction, so that the crystals can always flow into the sliding tube with the oil and be effectively intercepted. The sliding tube continuously collects the crystals generated in the oil, reducing the adhesion of the crystals on the inner wall of the inner cylinder or the stirring part. After the cooling and crystallization process is completed, the refined camellia oil is discharged, and the mounting mechanism drives the sliding tube to move out as a whole, so that the intercepting nets can be conveniently disassembled for centralized cleaning of the collected crystals.

[0044] In order to enable the above objects, features and advantages of the present application to be more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0046] The present application will be described below with reference to the accompanying drawings and specific embodiments. Figures 1 to 15 The camellia oil refining cooling device provided according to some embodiments of the present application is described.

[0047] As Figure 2 , Figure 10As shown, the camellia oil refining and cooling device provided by some embodiments of the present application comprises a device box 110, an inner cylinder 120, a cooling mechanism 200, a stirring mechanism 300, a mounting mechanism 400, an intercepting mechanism 500 and a flip mechanism 600. The inner cylinder 120 is arranged on the device box 110 and serves as a container for the camellia oil. The cooling mechanism 200 is arranged inside the inner cylinder 120 and serves to provide a cooling medium for the camellia oil. The stirring mechanism 300 is arranged inside the inner cylinder 120. The mounting mechanism 400 is arranged on the stirring mechanism 300. The intercepting mechanism 500 is arranged on the mounting mechanism 400. The intercepting mechanism 500 comprises a sliding tube 510 arranged on the mounting mechanism 400 in a sliding manner. The sliding tube 510 is in a hollow cylindrical shape. Two intercepting nets are arranged on both sides of the sliding tube 510 and serve to intercept the crystals inside the sliding tube 510. The flip mechanism 600 is connected to the mounting mechanism 400. The flip mechanism 600 can control the opening and closing of the intercepting nets on both sides of the sliding tube 510 according to the rotating direction of the stirring mechanism 300.

[0048] In this embodiment, the camellia oil to be cooled is poured into the inner cylinder 120. The cooling mechanism 200 is started to reduce the oil temperature in the inner cylinder 120 by the cooling medium. The stirring mechanism 300 is started synchronously to rotate at a low speed to uniformly cool the oil. As the oil temperature gradually decreases, the wax and oil ester in the camellia oil begin to precipitate crystals. In this process, the intercepting mechanism 500 moves synchronously with the stirring mechanism 300. When the stirring mechanism 300 rotates clockwise, the sliding tube 510 slides along the mounting mechanism 400. The flip mechanism 600 acts synchronously to control the intercepting net on the windward side of the sliding tube 510 to open and the leeward side to close. The oil carrying the crystals enters the sliding tube 510 through the opened intercepting net and is intercepted by the closed intercepting net on the other side. If the stirring mechanism 300 rotates counterclockwise, the sliding tube 510 slides reversely. The flip mechanism 600 reversely controls the opening and closing states of the intercepting nets to ensure that the crystals can always flow into the sliding tube 510 with the oil and be effectively intercepted. The sliding tube 510 continuously collects the crystals generated in the oil to reduce the degree of adhesion of the crystals to the inner wall of the inner cylinder 120 or the stirring components. After the cooling and crystallization process is completed, the refined camellia oil is discharged. The mounting mechanism 400 drives the sliding tube 510 to move out as a whole, so that the intercepting nets can be conveniently detached for centralized cleaning of the collected crystals.

[0049] In this design, the crystals can be captured and collected in a directional manner by the cooperation of the intercepting mechanism 500 and the flip mechanism 600 to reduce the degree of wax scale formed by the crystals on the inner wall of the device or the stirring components, reduce the difficulty of impurity filtration of the subsequent filtering equipment and reduce the cleaning cost of the device.

[0050] In some possible embodiments, as shown in FIG. 6, the camellia oil refining and cooling device comprises a device box 110, an inner cylinder 120, a cooling mechanism 200, a stirring mechanism 300, a mounting mechanism 400, an intercepting mechanism 500 and a flip mechanism 600. Figures 1 to 4As shown, it also includes: a control panel 111, located on the outside of the equipment box 110; a top cover 130, located on the top of the inner cylinder 120; an oil inlet pipe 131, located on the top cover 130; an inspection door 132, movably installed on the top cover 130; an outer cylinder 140, located on the outside of the inner cylinder 120, and the top cover 130 covers the outer cylinder 140; and a drain pipe 150, located at the bottom of the inner cylinder 120, the bottom of which has a funnel-shaped structure.

[0051] In this embodiment, the control panel 111 is connected to the cooling mechanism 200 and the stirring mechanism 300 via electrical circuits to achieve automated control of the device; the oil inlet pipe 131 can be connected to upstream refining equipment, such as the oil outlet pipe of the deodorization process, to facilitate the injection of camellia oil into the inner cylinder 120; the inspection door 132 is movably installed on the top cover 130 and can be manually opened or closed, facilitating the installation and disassembly of the interception mechanism 500 by operators, and also facilitating the observation of the internal condition of the inner cylinder 120 when the equipment is stopped; the outer cylinder 140 is coaxially sleeved on the outside of the inner cylinder 120, forming an annular cavity with the inner cylinder 120, which serves as heat insulation and reduces heat exchange between the inner cylinder 120 and the external environment; the drain pipe 150 is connected to the lowest point of the bottom of the inner cylinder 120, and the bottom of the inner cylinder 120 is designed as a funnel-shaped structure, which allows the cooled and crystallized camellia oil to naturally converge to the drain port under gravity, avoiding oil residue at the bottom of the inner cylinder 120, while reducing crystal deposition at the bottom and reducing cleaning difficulty.

[0052] In some possible embodiments, such as Figure 4 , Figure 5 As shown, the cooling mechanism 200 includes: a cooler 210, which is disposed inside the equipment box 110; an inlet pipe 220, which is connected to the output end of the cooler 210; a return pipe 230, which is connected to the input end of the cooler 210; and a heat exchange tube 240, which is spirally disposed inside the inner cylinder 120, and whose two ends are respectively connected to the inlet pipe 220 and the return pipe 230.

[0053] In this embodiment, the cooler 210 cools the cooling medium to a preset temperature. Driven by the pump built into the cooler 210, the low-temperature medium is transported to the spiral heat exchange tube 240 through the liquid inlet pipe 220. When the low-temperature cooling medium flows in the heat exchange tube 240, it exchanges heat with the camellia oil in the inner cylinder 120. The cooling medium flowing in the heat exchange tube 240 transfers its cooling capacity to the camellia oil, absorbing the heat of the oil and causing the temperature of the camellia oil to gradually decrease. As the cooling medium absorbs heat, its own temperature rises and it flows back to the cooler 210 through the liquid return pipe 230, cools down again, and enters the heat exchange tube 240 through the liquid inlet pipe 220, forming a continuous cycle.

[0054] In some possible embodiments, such as Figure 6 , Figure 7As shown, the stirring mechanism 300 comprises: a motor 310 arranged on the top of the top cover 130; a rotating shaft 320 connected with the output shaft of the motor 310; and a plurality of stirring blades 330 arranged on the rotating shaft 320 at intervals.

[0055] In this embodiment, the motor 310 drives the rotating shaft 320 and the stirring blades 330 to rotate. When the stirring blades 330 rotate, the camellia oil in the inner cylinder 120 is pushed to flow in an arc trajectory, forming a circulation path upward from the bottom of the inner cylinder 120 and downward along the inner wall, so that the camellia oil in different regions of the inner cylinder 120 is fully mixed, the local temperature difference caused by the spiral heat exchange pipe 240 is eliminated, and the crystal aggregation caused by local supercooling is avoided.

[0056] In some possible embodiments, as shown in Figures 6 to 9 As shown, each mounting mechanism 400 comprises: a fixed frame 410 sleeved on the rotating shaft 320; two fixed sleeves 411 arranged on the two sides of the fixed frame 410; two mounting frames 420 detachably arranged on each fixed sleeve 411; each mounting frame 420 comprises: a plurality of support rods, a plurality of threaded holes are formed in each support rod; a plug-in rod 421 is arranged on the mounting frame 420, and a plug-in groove adapted to the plug-in rod 421 is formed in the fixed sleeve 411; a mounting ring 430 is arranged between adjacent two support rods on the mounting frame 420, the inner wall of the mounting ring 430 is a smooth arc surface, and the outer wall of the sliding tube 510 is a smooth cylindrical surface; and two bolts 431 are arranged in the mounting ring 430 and connected with the threaded holes in the support rods.

[0057] In this embodiment, the sliding tube 510 is located in the mounting ring 430. According to actual needs, a corresponding number of mounting rings 430 are mounted on the mounting frame 420 and fixed by screws, so that the mounting frame 420 is inserted into the plug-in groove of the fixed sleeve 411 through the plug-in rod 421. When the rotating shaft 320 rotates with the motor 310, the fixed frame 410 drives the two fixed sleeves 411 and the mounting frame 420 to rotate synchronously, the mounting ring 430 moves with the mounting frame 420, and then drives the sliding tube 510 to rotate in the oil. Under the constraint of the smooth inner wall of the mounting ring 430, the sliding tube 510 can rotate synchronously with the mounting frame 420 and can slide axially according to the flow resistance of the oil.

[0058] In some possible embodiments, as shown in Figures 10 to 13As shown, each interception mechanism 500 further includes: a first interception net 511, disposed at the bottom of the sliding tube 510; two tube covers 520, symmetrically disposed at both ends of the sliding tube 510, each tube cover 520 having a rotating shaft, and a support seat for supporting the rotation of the rotating shaft being disposed on the sliding tube 510; two second interception nets 521, respectively disposed inside each tube cover 520; and two locking components, symmetrically disposed on both sides of each tube cover 520; each locking component includes: a locking pin 530, fixedly connected to the tube cover 520; an elastic element 540, rotatably connected to the heat exchange tube 240, the elastic element 540 having a support shaft; and a locking block 541, fixedly connected to the elastic element 540 and adapted to the locking pin 530.

[0059] In this embodiment, when the motor 310 drives the rotating shaft 320 to rotate clockwise, the rotating shaft 320 drives the mounting bracket 420 and the mounting ring 430 to move clockwise synchronously. As the sliding tube 510 rotates with the mounting ring 430, it experiences reverse resistance from the oil, which pushes the sliding tube 510 to move along the inner wall of the mounting ring 430 towards the leeward side until one side of the outer wall of the sliding tube 510 contacts the mounting ring 430. During the sliding process, the sliding tube 510 contacts the flip-top mechanism 600, pushing the elastic element 540 to disengage the locking block 541 from the locking pin 530. The tube cover 520 opens to a 45° angle with the axis of the sliding tube 510. The sliding tube 510 continues to move until the tube cover 520 opens to 90°. The second intercepting net 521 on this side retracts with the tube cover 520, and the leeward side tube cover 520 is no longer restricted by the flip-top mechanism 600. Under the influence of gravity, the system rotates and closes around the support base. The locking pin 530 automatically engages with the locking block 541 slot. The second intercepting net 521 fits against the leeward side opening of the sliding tube 510, forming a closed intercepting surface. The oil carrying crystals flows towards the windward open inlet of the sliding tube 510 in the direction of rotation and smoothly enters the interior of the sliding tube 510. The crystals are pushed by the oil and move towards the leeward side, where they are intercepted by the closed second intercepting net 521. The oil flows out of the sliding tube 510 through the mesh of the second intercepting net 521 and continues to participate in the circulation and cooling within the inner cylinder 120. If the process requires switching the stirring direction, the rotating shaft 320 drives the mounting bracket 420 and the mounting ring 430 to move counterclockwise synchronously. The sliding tube 510 slides along the inner wall of the mounting ring 430 towards the new leeward side, and the tube covers 520 on both sides switch to the open state through the flip-top mechanism 600.

[0060] In this design, the two side caps 520 automatically open and close accordingly through intermittent forward and reverse rotation, preventing long-term unidirectional rotation from causing crystal accumulation and clogging of the interception net.

[0061] In some possible embodiments, such as Figure 14 , Figure 15As shown, the flip cover mechanism 600 includes two push posts 610 symmetrically arranged on both sides of the mounting ring 430, and the push posts 610 are not in the same horizontal plane as the support shaft of the elastic member 540; two push frames 620 symmetrically arranged on the top of the mounting ring 430; and two push rods 630 arranged on both sides of the rotating shaft of the pipe cover 520, and each push rod 630 is in contact with the push frame 620.

[0062] In this embodiment, the stirring mechanism 300 drives the rotating shaft to rotate clockwise, the mounting ring 430 rotates synchronously with the rotating shaft, and the sliding pipe 510 slides along the mounting ring 430 to the leeward side under the reverse resistance of the oil liquid. During the sliding process of the sliding pipe 510, the end of the push post 610 first contacts the middle part of the elastic member 540, so that the elastic member 540 rotates around the support shaft, thereby driving the locking block 541 to disengage from the locking pin 530 of the pipe cover 520. The sliding pipe 510 continues to slide, the push post 610 pushes the locking block 541, so that the pipe cover 520 rotates relative to the mounting ring 430. At this time, the pipe cover 520 and the sliding pipe 510 are at an angle of 45°, and the sliding pipe 510 continues to slide, the push frame 620 contacts the push rod 630 on both sides of the rotating shaft of the pipe cover 520, and the pipe cover 520 is opened to 90°. The pipe cover 520 on this side is fixed, and if the rotating shaft is switched to rotate counterclockwise, the sliding pipe 510 slides reversely under the resistance of the oil liquid, the push rod 630 is separated from the push frame 620, and the push post 610 is separated from the elastic member 540. The pipe cover 520 on this side loses the force of the push post 610 and the push frame 620, and rotates counterclockwise around the rotating shaft under the action of its own gravity. The locking pin 530 and the locking block 541 are re-engaged, and the pipe cover 520 is closed. The pipe cover 520 on the other side is opened, and the state exchange of the pipe covers 520 on both sides is completed, thereby ensuring that the crystal is continuously intercepted.

[0063] In some possible embodiments, as shown in FIG. 6, the stirring mechanism 300 includes a plurality of groups of stirring blades 330 and fixed frames 410, and the stirring blades 330 and the fixed frames 410 are alternately arranged on the rotating shaft 320. Figure 6 As shown, the stirring blades 330 and the fixed frames 410 are alternately arranged on the rotating shaft 320.

[0064] In this embodiment, the stirring blades 330 and the fixed frames 410 are alternately arranged, which avoids local oil liquid stagnation caused by concentrated installation. Through the synergistic effect of multiple groups of stirring blades 330, the oil liquid forms a spiral circulation, thereby improving the uniformity of flow rate.

[0065] The camellia oil refining cooling device, when working, injects the camellia oil to be cooled into the inner cylinder 120 through the oil inlet pipe 131, the inner cylinder 120 serving as a containing container, the outer cylinder 140 sleeved outside the inner cylinder 120 forming a heat insulation layer through the annular cavity, reducing the heat exchange between the inner cylinder 120 and the outside, ensuring the stability of the cooling environment, the oil injection amount being controlled within 80% of the volume of the inner cylinder 120, reserving space for subsequent stirring and crystal interception, the refrigerator 210 inside the equipment box 110 being started, the cooling medium being reduced to a preset temperature, the low-temperature medium being transported to the spiral heat exchange pipe 240 inside the inner cylinder 120 through the liquid inlet pipe 220 under the driving of the built-in pump, the low-temperature medium in the heat exchange pipe 240 exchanging heat with the camellia oil in the inner cylinder 120, absorbing the heat of the oil, the cooling medium being warmed after heat absorption flowing back to the refrigerator 210 through the liquid return pipe 230, being reused after being cooled again, forming a closed cooling loop, the rotating shaft 320 being rotated through the motor 310, the stirring blades 330 pushing the oil to form a spiral circulation with the bottom upwards and along the inner wall downwards in an arc trajectory, eliminating the local temperature difference caused by the heat exchange pipe 240, as the oil temperature decreases, the wax and oil in the camellia oil begin to precipitate crystals, when the stirring mechanism 300 rotates clockwise, the sliding pipe 510 slides to the leeward side along the mounting ring 430 under the reverse resistance of the oil, the push column 610 on the sliding pipe 510 first contacts the elastic member 540 on this side, drives the lock block 541 to disengage from the lock pin 530, the push column 610 continues to push the lock block 541, so that the pipe cover 520 rotates around the support seat to 45° with the axis of the sliding pipe 510, the sliding pipe 510 continues to slide, the pushing frame 620 on the top of the mounting ring 430 abuts against the toggle lever 630 on both sides of the rotating shaft of the pipe cover 520, so that the pipe cover 520 is opened to 90°, the second interception net 521 on the windward side is retracted, forming an open inlet, the oil carrying crystals enters the sliding pipe 510 from the open inlet, is intercepted by the second interception net 521 on the leeward side, flows out through the interception mesh, and continues to participate in the circulation, after a period of time, the rotating shaft 320 rotates counterclockwise, the sliding pipe 510 slides reversely, the toggle lever 630 on the original windward side disengages from the pushing frame 620, the pipe cover 520 is closed under the action of its own gravity, the lock pin 530 automatically engages into the lock block 541 for locking, the push column 610, the pushing frame 620 and the toggle lever 630 on the other side repeat the above actions, so that the opening states of the pipe covers 520 on both sides are exchanged, ensuring that the crystals are always directed into the sliding pipe 510 to be intercepted, and preventing the crystals from accumulating to block the interception net due to long-term unidirectional rotation, after the cooling and crystallization process is completed, the cooling and stirring are stopped, the valve port of the liquid outlet pipe 150 at the lowest part of the funnel-shaped structure at the bottom of the inner cylinder 120 is opened, the oil naturally converges and is discharged under its own gravity, the movable maintenance door 132 on the top cover 130 is opened, the mounting bracket 420 is taken out from the fixed sleeve 411 through the plug-in rod 421, and cleaning is performed.
