Description

Technical Field

[0001] This utility model belongs to the field of tea oil processing technology, specifically a tea oil processing dehydration and deacidification mechanism. Background Technology

[0002] Camellia oil is a high-quality edible oil with high nutritional and medicinal value. However, dehydration and deacidification are crucial steps in its processing because camellia oil contains a certain amount of water and free fatty acids, which can affect its quality and storage stability. Camellia oil is a plant oil extracted from camellia seeds and is rich in monounsaturated fatty acids, vitamin E, and other antioxidants. However, the extraction process results in a certain amount of water and free fatty acids, which can impact the quality of the camellia oil.

[0003] Existing tea oil processing dehydration and deacidification facilities have the following main shortcomings:

[0004] Existing tea oil processing dehydration and deacidification facilities mostly use in-line heating tubes or tank wall heating methods, which have limited contact area with tea oil. Moreover, the stirring devices are mostly simple paddles, resulting in a single flow trajectory for tea oil. This can easily lead to problems such as local overheating or local moisture residue. The dehydration time is long and the energy consumption is high. The deacidifying agent is delivered manually or by a simple pump, which has large errors in the amount added and can easily lead to over-acidification or under-acidification. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a tea oil processing dehydration and deacidification mechanism, which solves the problems of existing technologies that mostly use in-line heating tubes or tank wall heating methods, resulting in limited contact area with tea oil, and the stirring devices are mostly simple paddles, with a single flow trajectory of tea oil, which easily leads to local overheating or local moisture residue, long dehydration time, and high energy consumption.

[0008] As a further embodiment of this utility model: all three scrapers are attached to the inner wall of the deacidification tank, and a heating tube is provided on the outer side of the spiral blade on the other side and inside the dehydration tank. One end of the heating tube penetrates the upper inner wall of the dehydration tank and leads to the upper end face of the dehydration tank, and an electric suction pump is fixedly connected to the end.

A peristaltic pump is provided at the center of the lower inner wall of the feeding box. The output end of the peristaltic pump passes through the lower inner wall of the feeding box and leads to the lower end face of the feeding box. A flow pipe is fixedly connected to the end of the flow pipe. A flow meter is provided at the center of the front end face of the flow pipe. The output end of the flow pipe passes through the upper end face of the deacidification tank and leads to the inside of the deacidification tank.

[0011] As a further embodiment of this utility model: the filter discharge structure includes a first discharge pipe, which is located at the center of the lower end face of the deacidification tank. A filter box is provided at the center of the lower end face of the first discharge pipe.

[0012] As a further embodiment of this utility model: one end of each of the three lifting boxes penetrates the front inner wall of the filter box and leads to the front end face of the three filter boxes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a structure combining a spiral heating tube and spiral blades inside the dehydration tank. The heating tube is spirally wrapped around the outside of the spiral blades, forming a nested three-dimensional working space. When the servo motor drives the spiral blades to rotate and stir the tea oil, the tea oil forms a spiral upward flow trajectory inside the tank, making full contact with the spiral heating tube. This significantly increases the heat exchange area and contact time, avoiding the contradiction between local overheating leading to tea oil deterioration and local insufficient temperature leading to incomplete dehydration. This improves dehydration efficiency while reducing heat loss and lowering processing energy consumption.

[0016] This invention, through a closed-loop control combination of a peristaltic pump, flow pipe, and flow meter, can precisely control the amount of deacidifying agent and alkali solution added. Furthermore, the three annularly arranged scrapers on the rotating rod inside the deacidification tank are in close contact with the tank wall and can scrape off the adhering tea oil in real time as they rotate synchronously with the rotating rod. This avoids the problem of excessive or insufficient addition of deacidifying agent due to relying on experience, and also prevents tea oil from adhering to the tank wall, causing raw material waste and incomplete reaction.

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution:

[0024] A tea oil processing dehydration and deacidification device, comprising:

[0025] A dehydration tank 1 is provided, and a deacidification tank 2 is provided on one side of the dehydration tank 1. Both the outer walls of the dehydration tank 1 and the deacidification tank 2 are provided with support structures 4. A feed hopper 3 is provided at the center of the upper end face of the dehydration tank 1 near one side. A feed pump 6 is provided between the dehydration tank 1 and the deacidification tank 2.

Both the dehydration tank 1 and the deacidification tank 2 are provided with dehydration and deacidification structures 5 at the center of their interiors. A material racking structure 7 is provided at the center of the upper end face of the deacidification tank 2 near one side. A filter discharge structure 8 is provided at the center of the lower end face of the deacidification tank 2.

[0026] The two dehydration and deacidification structures 5 include two servo motors 501, which are respectively located at the center of the upper end face of the dehydration tank 1 and the deacidification tank 2. The output ends of both servo motors 501 are fixedly connected to rotating rods 502. One end of each rotating rod 502 passes through the upper end face of the dehydration tank 1 and the deacidification tank 2, respectively, and extends into their respective interiors. Spiral blades 503 are fitted at the center of the outer wall of each rotating rod 502. Three scrapers 507 are arranged in a ring near the upper center of the outer wall of one rotating rod 502. The scrapers 507 are all attached to the inner wall of the deacidification tank 2. A heating tube 504 is provided on the outside of the spiral blades 503 on the other side and inside the dehydration tank 1. One end of the heating tube 504 passes through the upper inner wall of the dehydration tank 1 and leads to the upper end face of the dehydration tank 1. An electric suction pump 505 is fixedly connected to the end of the heating tube 504. The other end of the heating tube 504 passes through one inner wall of the dehydration tank 1 and leads to one side of the dehydration tank 1. A first solenoid valve 506 is fixedly connected to the end of the first solenoid valve 506. A connecting pipe is provided at one end of the first solenoid valve 506 and the input end of the electric suction pump 505. The heating tube 504 is a spiral tube.

[0027] The servo motor 501 is started to drive the rotating rod 502 to rotate, which in turn drives the spiral blades 503 to stir the tea oil. At the same time, the heating tube 504 has a spiral tube structure to increase the contact area with the tea oil. The electric suction pump 505 is connected to steam and draws in hot steam to heat the tea oil in the dehydration tank 1. During the heating process, the water in the tea oil evaporates. The evaporated water vapor can be discharged through the circulation path of the heating tube 504 and controlled by the first solenoid valve 506, thus achieving the dehydration process.

[0028] The two support structures 4 include four support plates 401, which are arranged in pairs, one above the other. The two sets of support plates 401 are arranged vertically and vertically at the upper center of the outer wall of the dehydration tank 1 and the deacidification tank 2. Eight columns 402 are arranged in a ring between the two sets of support plates 401.

[0029] The feeding structure 7 includes a feeding box 701, which is located on one side of the center of the upper end face of the deacidification tank 2. A peristaltic pump 702 is located at the center of the lower inner wall of the feeding box 701.

The alkaline solution stored in the feeding box 701 is pumped out by the peristaltic pump 702, passes through the flow pipe 703, and is accurately delivered to the deacidification tank 2 by real-time monitoring of the flow rate by the flow meter 704. The solution is fully mixed and reacted with the tea oil to achieve deacidification treatment.

[0030] The filtration discharge structure 8 includes a first discharge pipe 801, which is located at the center of the lower end face of the deacidification tank 2. A filter box 802 is located at the center of the lower end face of the first discharge pipe 801. Three sliding frames 803 are arranged vertically near the upper center of the filter box 802. Each of the three sliding frames 803 is slidably connected to a lifting box 804 at its center. One end of each of the three lifting boxes 804 penetrates the front inner wall of the filter box 802 and extends to the front end face of the filter box 802. A second discharge pipe 805 is located at the center of the lower end face of the filter box 802. A second discharge pipe 805 is located at the center of the upper lifting box 804. A filter screen 806 is provided, and a filter gauze 807 is provided at the lower end of the filter screen 806 and inside the carrying box 804. A filter membrane 808 is provided at the lower end of the filter gauze 807 and inside the carrying box 804. A flow guide 809 is provided at the center of the lower inner wall of the filter box 802. The tea oil enters the filter box 802 through the first discharge pipe 801, and passes through the filter screen 806 in the three carrying boxes 804 in sequence to filter large particles of impurities, the filter gauze 807 to filter fine impurities, and the filter membrane 808 to filter tiny impurities. Under the guidance of the flow guide 809, the pure tea oil is finally discharged through the second discharge pipe 805.

[0031] The working principle of this utility model is as follows: The support structure 4 provides a stable foundation for the entire equipment. Two sets of support plates 401 are respectively fixed around the outer walls of the dehydration tank 1 and the deacidification tank 2. The upper and lower support plates 401 are connected by sixteen columns 402 to form a ring reinforcement for the dehydration tank 1 and the deacidification tank 2. The three support legs 403 at the bottom of the dehydration tank 1 and the deacidification tank 2 lift the entire equipment off the ground, avoiding temperature loss or contamination caused by direct contact between the dehydration tank 1 and the deacidification tank 2 and the ground, while ensuring sufficient operating space. The tea oil to be processed is injected into the dehydration tank 1 through the feed hopper 3. The servo motor 501 is started to drive the rotating rod 502 to rotate, which in turn drives the outer spiral blades 503 to rotate. When the spiral blades 503 rotate synchronously with the rotating rod 502... The tea oil in the dehydration tank 1 is thoroughly stirred to ensure even distribution and prevent localized overheating or incomplete dehydration. The heating tube 504 has a spiral design to increase the contact area with the tea oil. The electric suction pump 505 draws in a heat medium, such as high-temperature heat transfer oil or hot steam, through a connecting pipe. After entering the spiral heating tube 504, the heat medium circulates within the tea oil and heats it through heat conduction. The water in the tea oil evaporates into water vapor, and some of the water vapor can diffuse through the gaps in the heating tube 504. Finally, the first solenoid valve 506 controls the opening and closing of the outlet of the heating tube 504 and discharges it through the connecting pipe, thus achieving the purpose of dehydration. The spiral structure of the heating tube 504 ensures full contact between the heat medium and the tea oil, improving heating efficiency and shortening the dehydration time.

[0032] After dehydration, the feed pump 6 starts, pumping the dehydrated tea oil from the bottom of the dehydration tank 1 into the deacidification tank 2, achieving continuous transport between the two tanks and avoiding inefficiency or contamination caused by manual transfer. The dehydration and deacidification structure 5 inside the deacidification tank 2 starts simultaneously, driving the rotating rod 502 and spiral blade 503 to rotate via the servo motor 501, stirring the incoming tea oil to prepare for the subsequent deacidification reaction. The scraper 507 rotates with the rotating rod 502, scraping off the tea oil adhering to the tank wall to avoid raw material waste and ensure uniform mixing of the tea oil inside the tank. The feed structure 7 is responsible for adding deacidifying agents, such as food-grade alkali, to the deacidification tank 2 to neutralize free fatty acids in the tea oil. The feed box 701 stores the deacidifying agent, and the peristaltic pump 702 pumps the deacidifying agent into the flow pipe 703. The flow meter 704 monitors the delivery volume in real time to ensure the deacidifying agent... The deacidifying agent is precisely injected into the deacidification tank 2 according to the preset ratio. The deacidifying agent and tea oil are fully mixed under the stirring of the spiral blade 503, and a neutralization reaction occurs. The tea oil after deacidification contains a small amount of soap residue and impurities, which need to be purified before being discharged. The tea oil enters the filter box 802 through the first discharge pipe 801, flows through three lifting boxes 804 in sequence, and is installed in the filter box 802 through the sliding frame 803, which can be pulled out and removed. It passes through the filter screen 806 to filter out large particles of impurities and unreacted solid alkali particles in the tea oil, through the filter gauze 807 to filter out smaller suspended impurities and soap residue particles, and through the filter membrane 808 to filter out tiny impurities or colloids, thus purifying the tea oil. The filtered pure tea oil is guided to the center by the flow guide 809 and discharged through the second discharge pipe 805, completing the entire tea oil processing dehydration, deacidification and purification process.

[0033] Furthermore, the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
