Description

Technical Field

[0001] The invention relates to an oil heating device, in particular to an oil heating and aroma enhancement device. Background Art

[0002] Oil refers to plant seeds or kernels containing oil bodies, including but not limited to: peanuts, soybeans, rapeseed, sesame, flaxseed, tea seeds, walnut kernels, safflower seeds, celandine seeds, avocado seeds, flax seeds, tung seeds, sea buckthorn seeds, Xanthoceras sorbifolia seeds, pomelo seeds, pepper seeds, papaya seeds, and watermelon seeds. They need to be heated to enhance the flavor before oil extraction.

[0003] However, the existing heating equipment has a complex structure, such as the circulating tunnel drying equipment and its control method disclosed in Chinese patent CN110186268A, which has a complex structure, and the loading and unloading of oil requires manual operation, which has low work efficiency and requires frequent shutdown for loading and unloading of oil. At the same time, the infrared heating tube is close to the heated oil, and the infrared heating tube is easily damaged by external impact or accidental collision during use; because the oil contains dust, the surface of the infrared lamp tube is not cleaned for a long time during the production process, so that the pollutants on the surface of the tube body accumulate thicker and thicker, resulting in the surface temperature of the electric heating tube cannot be dissipated in time, heat accumulates, and the internal temperature is too high, resulting in cracking and bursting of the tube. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an oil heating and aroma device which has a simple structure, can automatically load and discharge materials, can effectively protect the infrared heating tube, and can automatically clean to prevent dust accumulation from affecting the heating. The specific technical scheme is as follows:

[0005] The oil heating and flavoring device comprises a circulation pipeline, a feeding plate, a traction chain and a traction device, wherein the circulation pipeline is provided with a feeding port and a discharging port; the device also comprises: a transparent cover, wherein a plurality of transparent covers are provided along the length direction of the circulation pipeline and are located inside the circulation pipeline, wherein the feeding plate is provided with a scraping trough matching the transparent cover; and an infrared heating tube, wherein the infrared heating tube is arranged inside the transparent cover.

[0006] By adopting the above technical solution, the pipeline chain conveyor is an existing mature technology, but the existing pipeline chain conveyors do not have a heating function. By combining the pipeline chain conveyor with an infrared heating tube, continuous feeding and automatic heating can be achieved.

[0007] The transparent cover can be a glass cover or a high temperature and friction resistant plastic cover. The transparent cover can protect the infrared heating tube and prevent the infrared heating tube from being damaged due to collision or accumulating oil and dust, which leads to heat accumulation and tube burst. The scraper groove on the feeding plate matches the transparent cover. The feeding plate can clean the surface of the transparent cover when moving, remove the oil or dust on the transparent cover, ensure good light transmittance, and then ensure the heating effect, improve heating efficiency, and reduce loss.

[0008] Furthermore, transparent covers are provided on both sides of the circulation pipeline, and infrared heating tubes are installed in the transparent covers.

[0009] By adopting the above technical solution, multiple infrared heating tubes can improve the heating efficiency.

[0010] Furthermore, it also includes: an air inlet duct, which is arranged on the side of the circulation duct and communicated with the transparent cover, one side of the air inlet duct is provided with at least one air inlet, and the other side is provided with at least one air outlet; an induced draft duct, which is at least one, one end of which is arranged on one side of the circulation duct and communicated with the circulation duct, and the other end of which is arranged on the air outlet; and a fan, which is fixed on the induced draft duct or the circulation duct, and is used for introducing the hot air in the air inlet duct into the circulation duct.

[0011] By adopting the above technical solution, hot air can improve the uniformity of temperature, thereby improving the heating effect and heating efficiency, and fully utilize the heat of the infrared heater to achieve energy saving and reduce costs.

[0012] Furthermore, it also includes a hood, which is arranged on the feeding plate and protrudes to one side of the feeding plate. The hood is provided with mesh holes, and the mesh holes are smaller than the diameter of the oil.

[0013] By adopting the above technical solution, the hood is used to facilitate hot air circulation and effectively prevent oil from clogging the hood.

[0014] Furthermore, the hood is arranged at the center of the feeding plate.

[0015] By adopting the above technical solution, the wind hood is set at the center or below the center of the feeding plate, so that the hot air can flow along the center of the circulation pipe. Since there are gaps between the particles, the hot air can blow through the gaps to improve the heating inside the oil, solve the problem of weak heating ability of infrared heating on the oil in the middle of the oil, and ensure that all the oil is effectively heated.

[0016] Furthermore, the traction chain is located at the center of the feeding plate, and two hoods are provided, respectively located on both sides of the traction chain.

[0017] Furthermore, the hood is provided with an air door, which is rotatably mounted on the feeding plate, and is used to close the hood so that hot air can pass through the circulation duct in one direction.

[0018] By adopting the above technical solution, the air door allows the hot water to circulate and heat in a fixed direction, preventing the feed port from sucking in cold air and affecting the heating effect.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The oil heating and flavoring device provided by the present invention adopts a pipeline chain conveying method to realize automatic feeding and discharging of oil, has a simple structure and is easy to use. The infrared heating tube is effectively protected by the lampshade, and the lamp tube has a long service life. At the same time, the lampshade is automatically cleaned to ensure the heating effect, and the production continuity is good and the processing efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 2 It is a partial cross-sectional view of an oil heating and flavoring device;

[0023] Figure 3 is along Figure 1 Section view along line AA. DETAILED DESCRIPTION

[0024] The present invention will be further described with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] like Figures 1 to 3 As shown, the oil heating and flavoring device includes a circulation pipeline 1, a feeding plate 2, a traction chain 4 and a traction device, and the circulation pipeline 1 is provided with a feeding port 11 and a discharging port 13; it also includes: a transparent cover 6, which is provided with multiple transparent covers 6 along the length direction of the circulation pipeline 1 and is located inside the circulation pipeline 1, and the feeding plate 2 is provided with a scraping trough matching the transparent cover 6; an infrared heating tube 5, which is arranged inside the transparent cover 6.

[0027] The pipeline chain conveyor is an existing mature technology, but the existing pipeline chain conveyors do not have a heating function. By combining the pipeline chain conveyor with the infrared heating tube 5, continuous feeding and automatic heating can be achieved.

[0028] The transparent cover 6 can be a glass cover or a plastic cover that is resistant to high temperature and friction. The transparent cover 6 can protect the infrared heating tube 5, prevent the infrared heating tube 5 from being damaged due to collision, or prevent the accumulation of oil and dust, which leads to heat accumulation and tube burst. The scraper groove on the feed plate 2 is just matched with the transparent cover 6. The feed plate 2 can clean the surface of the transparent cover 6 when moving, clean the oil or dust on the transparent cover 6, ensure good light transmittance, and then ensure the heating effect, improve the heating efficiency, and reduce the loss. When the transparent cover 6 adopts a discontinuous cover shell, the height of the transparent cover 6 protruding from the inside of the circulation pipeline 1 is small, so that the height of the scraper groove is small, and the height of the scraper groove is smaller than the diameter of the oil, so that when the feed plate 2 pushes the oil, the oil will not leak from the scraper groove to the next feed plate 2, ensuring that all the oil moves with the feed plate 2. When the transparent cover 6 is a continuous cover shell, the height of the transparent cover 6 protruding from the inside of the circulation pipeline 1 can be large. The transparent cover 6 can be arc-shaped or rectangular. The transparent cover 6 protrudes into the inside of the circulation pipe 1 so that the transparent cover 6 can enter the inside of the oil pile, increase the contact area with the oil, and thus improve the heating effect on the oil.

[0029] In another embodiment, transparent covers 6 are provided on both sides of the circulation pipeline 1, and infrared heating tubes 5 are installed in the transparent covers 6. In fact, the transparent covers 6 can be arranged along the entire cross section of the circulation pipeline 1. Since the circulation pipeline adopts a rectangular pipeline, infrared heating tubes 5 are arranged on the upper and lower sides. This arrangement is convenient for installation, and too many heating tubes are likely to cause excessive temperature. A large number of infrared heating tubes 5 are arranged at the bottom of the circulation pipeline 1 to fully ensure the heating of the oil.

[0030] The circulation pipeline 1 is made of a steel pipe or a stainless steel pipe, and the feeding plate 2 is a high temperature resistant and friction resistant plastic plate, such as a polytetrafluoroethylene plate or other engineering plastic plate.

[0031] A plurality of infrared heating tubes 5 can improve the heating efficiency.

[0032] A feeding device is provided on the feed port 11 for feeding.

[0033] The oil is respectively located between two adjacent feeding plates 2 .

[0034] The traction device drives the traction chain 4, the traction chain 4 drives the feeding plate 2, and the feeding plate 2 pushes the oil to move in the circulation pipeline 1. The circulation pipeline 1 can be in various shapes such as circular, rectangular or S-shaped.

[0035] The infrared radiation is near-infrared and mid-infrared radiation with a wavelength of 0.76-4μm and a heating radiation function. The radiation temperature is 120-170℃ and the radiation time is 20-60 min.

[0036] The problem of dust affecting the life of infrared heating tubes and the easy combustion during the heating process of oil crops was solved, and the continuous production of the heating process was realized.

[0037] Embodiment 2

[0038] On the basis of the above-mentioned embodiment 1, it also includes an air inlet duct 71, which is arranged on the side of the circulation duct 1 and communicated with the transparent cover 6, and one side of the air inlet duct 71 is provided with at least one air inlet 72, and the other side is provided with at least one air outlet 73; an air induced draft duct 74, at least one air induced draft duct 74, one end of which is arranged on one side of the circulation duct 1 and communicated with the circulation duct 1, and the other end of the air induced draft duct 74 is arranged on the air outlet 73; a fan 75, the fan 75 is fixed on the air induced draft duct 74 or the circulation duct 1, and is used to introduce the hot air in the air inlet duct 71 into the circulation duct 1.

[0039] There is a gap between the feeding plate 2 and the circulation pipe 1 to facilitate the movement of the feeding plate 2, but the gap is smaller than the diameter of the oil, so the hot air can flow through the gap between the feeding plate 2 and the circulation pipe 1 in the circulation pipe 1.

[0040] The fan 75 realizes the circulation of wind, and the air inlet duct 71 sucks in the room's room temperature air. Since the infrared heating tube 5 is heating, the air entering the air inlet duct 71 can be heated, and the room temperature air is converted into hot air, and enters the interior of the circulation duct 1 through the air duct 74 to heat the oil. Since the oil is large particles, there are gaps between the oil. After the hot air passes through, the heating effect is effectively improved, that is, the heat exchange efficiency is improved. The hot air can heat and stir the air in the circulation duct 1 at the same time. The hot air can improve the uniformity of the temperature in the circulation duct 1, speed up the heating of the oil, and thereby improve the heating effect and heating efficiency, and make full use of the heat of the infrared heater to achieve energy saving and reduce costs.

[0041] The air inlet duct 71 is set according to specific conditions. A plurality of air induction ducts 74 can be set on the air inlet duct 71 to perform segmented heating to improve the utilization rate of heat energy. When the upper and lower sides of the circulation duct 1 are provided with infrared heating tubes 5 and transparent covers 6, two air inlet ducts 71 are provided, which are respectively located at the top and bottom of the circulation duct 1, and the infrared heating tubes 5 are both located in the air inlet duct 71.

[0042] The fan 75 can also be set on the circulation duct 1, and a suction pipe 12 is added to the circulation duct 1. The fan 75 is fixed on the suction pipe 12. At this time, the fan 75 circulates the hot air in the circulation duct 1 through suction, and when the fan 75 is set on the induced draft pipe 74, the hot air is pressed into the circulation duct 1.

[0043] Embodiment 3

[0044] Based on the above-mentioned embodiment 2, Figures 1 to 3 As shown, it also includes a hood 3, which is arranged on the feeding plate 2 and protrudes to one side of the feeding plate 2. The hood 3 is provided with mesh holes, and the mesh holes are smaller than the diameter of the oil.

[0045] Hot air can improve temperature uniformity, thereby improving heating effect and heating efficiency.

[0046] In order to increase the ventilation volume, the ventilation area needs to be increased, so the gap between the feed plate 2 and the circulation pipeline 1 cannot meet the requirements. If ventilation holes are opened on the feed plate 2, the ventilation area can be increased. The diameter of the ventilation holes needs to be smaller than the diameter of the oil, otherwise the oil will leak out from the ventilation holes on the feed plate 2. However, this method is easy to cause the oil to block the ventilation holes, and more ventilation holes need to be set at the same time, and more ventilation holes affect the strength of the feed plate 2, causing the feed plate 2 to break easily. Under the action of wind pressure, the oil is blocked on the ventilation holes and is not easy to fall, causing the ventilation volume to drop rapidly, the wind pressure damage is huge, and the hot air heating effect is very poor. If the gap between the top of the feed plate 2 and the circulation pipeline 1 is increased, the ventilation volume can be increased, but the oil is not easy to reach the top of the feed plate 2 under the action of gravity. This method causes hot air to circulate at the top of the oil, and the heating of the oil is very limited. The hot air heating effect is still very poor, so how to solve the hot air heating and improve the hot air heating effect is a very difficult thing.

[0047] The hood 3 can be made of a stainless steel mesh plate or a stainless steel mesh cover. The hood 3 is used to increase the ventilation area and facilitate hot air circulation. The hood 3 protrudes from the end face of the feeding plate 2, so that the oil will not completely cover the hood 3, and because the hood 3 is made of a mesh plate, it has many mesh holes, and all the mesh holes will not be blocked, which effectively prevents the oil from blocking the hood 3, and the hood is inserted into the oil, so it can improve the heat exchange effect with the oil. The use of a steel mesh is more effective, because the mesh of the steel mesh is smaller, and the steel mesh is less likely to be blocked by the material. If a steel mesh is used on the feeding plate 2, the effect is still poor, because the oil will accumulate at the steel mesh, resulting in a decrease in ventilation volume and a decrease in wind pressure. Therefore, the use of a protruding hood 3 can effectively solve these problems, ensure ventilation volume and heating effect, and be more economical.

[0048] Embodiment 4

[0049] On the basis of the above-mentioned third embodiment, the hood 3 is arranged at the center of the feeding plate 2 or at a position slightly below the center.

[0050] The hood 3 is arranged at the center or slightly below the center of the feeding plate 2, so that the hot air can flow along the center of the circulation pipe 11 and the hot air can fully pass through the oil. Since there are gaps between the oil particles, the hot air can blow through the gaps between the oil particles, thereby improving the heating inside the oil, solving the problem of weak heating ability of infrared heating for the intermediate oil in the oil pile accumulated in the circulation pipe 1, and ensuring that all the oil is effectively heated.

[0051] When the hood 3 is arranged at the center of the feeding plate 2, the traction chains 4 are arranged on both sides of the hood 3 to ensure that the feeding plate 2 is evenly stressed and keeps the feeding in a vertical state.

[0052] Embodiment 5

[0053] On the basis of the above-mentioned third embodiment, the traction chain 4 is located at the center of the feeding plate 2 , and two hoods 3 are provided, which are respectively located on both sides of the traction chain 4 .

[0054] The oil heating and flavoring device provided by the present invention adopts a pipeline chain conveying method to realize automatic feeding and discharging of oil, has a simple structure and is easy to use. The infrared heating tube is effectively protected by the lampshade, and the lamp tube has a long service life. At the same time, the lampshade is automatically cleaned to ensure the heating effect, and the production continuity is good and the processing efficiency is high.

[0055] Embodiment 6

[0056] On the basis of the above-mentioned third to fifth embodiments, a damper 8 is provided on the hood 3, and the damper 8 is rotatably mounted on the feeding plate. The damper 8 is used to close the hood 3 so that hot air can pass through the circulation duct 1 in one direction.

[0057] The air door 8 allows the hot water to circulate and heat in a fixed direction, thus realizing the function of a one-way air valve, and preventing the feed port 11 from sucking in cold air and affecting the heating effect.

[0058] The oil heating and aroma enhancement device provided by the present invention is mainly used for heating oil with larger particle size, such as peanuts, soybeans and the like.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
