Description

Technical Field

[0001] The utility model relates to the field of food processing equipment, in particular to an oil refining furnace. Background Art

[0002] In food production, oil refining means heating edible oil to a preset temperature and then mixing it with seasonings to form seasoned oil required for food production, so that the food has a certain flavor.

[0003] Existing oil refining equipment usually heats edible oil through a gas heater at the bottom or a heating coil wrapped on the outside. However, in the above heating methods, heat is transferred from the outside to the inside, and the heating efficiency is relatively low. Summary of the Utility Model

[0004] Therefore, to solve the above deficiencies, the utility model provides an oil refining furnace, including:

[0005] A furnace body, which includes an inner furnace and an outer furnace. The outer furnace wraps the outside of the inner furnace, and a sandwich layer is formed between the outer furnace and the inner furnace. A heating coil is wound in the sandwich layer;

[0006] A heater, and several heaters are provided. The several heaters are arranged at equal angles around the central axis of the inner furnace inside the inner furnace.

[0007] The utility model heats up through the heating coil and transfers heat from the outside to the inside. At the same time, the heaters arranged around the central axis of the inner furnace heat up and transfer heat from the center of the furnace body to the outside, so as to quickly heat the edible oil in the furnace body and improve the heating efficiency of the edible oil.

[0008] Further, it further includes a furnace cover, and the furnace cover is sealed at the opening on the top of the furnace body. The several heaters are all fixedly installed on the furnace cover.

[0009] Further, it further includes a first lifting assembly. The above-mentioned furnace cover is fixedly installed on the first lifting assembly, and the first lifting assembly drives the furnace cover to move linearly in the vertical direction.

[0010] The furnace cover is lifted by the first lifting assembly, so that the heater leaves the furnace body, and then it is convenient to clean the inside of the furnace body.

[0011] Further, it further includes a flipping assembly. The above-mentioned furnace body is installed on the flipping assembly, and the flipping assembly can drive the furnace body to rotate, so that the opening of the furnace body facing vertically upward moves to a position facing obliquely downward.

[0012] The furnace body is flipped by the flipping assembly, so as to facilitate the staff to clean and overhaul the furnace body.

[0013] Further, it further includes

[0014] The second lifting component;

[0015] A cleaning component, which is driven by the above-mentioned second lifting component to move linearly vertically to clean the grease on the inner side wall of the inner furnace;

[0016] Among them, the cleaning component includes a steam spray pipe, which is arranged around the inner side of the inner furnace. An air outlet nozzle is provided on one side of the steam spray pipe close to the inner side wall of the inner furnace, and the steam spray pipe is communicated with a high-pressure steam source.

[0017] High-pressure steam is sprayed on the side wall of the furnace body through the steam spray pipe. Under the action of the high-temperature steam, the viscosity of the grease attached to the side wall is reduced and it flows downward. At the same time, under the action of the high-pressure steam, the grease is driven downward, thereby realizing the cleaning of the side wall of the furnace body and reducing the labor intensity.

[0018] Furthermore, a notch matching the steam spray pipe is provided on the lower surface of the furnace cover corresponding to the steam spray pipe, and the steam spray pipe enters and exits the furnace cover through this notch.

[0019] When the furnace body is working, the steam spray pipe can be hidden inside the furnace cover, thus avoiding polluting the edible oil.

[0020] Furthermore, a sealing plate is provided below the steam spray pipe. When the steam spray pipe is accommodated inside the furnace cover, the lower surface of the sealing plate is flush with the lower surface of the furnace cover.

[0021] The edible oil is blocked by the sealing plate, thereby protecting the steam spray pipe hidden inside the furnace cover and preventing the edible oil from splashing and adhering to the steam spray pipe.

[0022] Furthermore, the cleaning component further includes a scraper, which is arranged on the periphery of the steam spray pipe. The scraper moves together with the steam spray pipe. The outer side of the scraper contacts the inner side wall of the inner furnace. The scraper cooperates with the sealing plate to seal the notch.

[0023] Furthermore, a first step is provided on one side of the scraper close to the sealing plate, and a second step is provided on one side of the sealing plate close to the scraper. The first step and the second step cooperate with each other for sealing;

[0024] The cleaning component further includes a connecting pin rod, which passes through the above-mentioned first step and second step and slides relatively with the scraper.

[0025] When the first lifting component drives the steam spray pipe and the sealing plate to move downward together, it drives the connecting pin rod to move together until the lower step surface of the top of the connecting pin rod contacts the upper surface of the first step, and then drives the scraper to move downward. At this time, a height difference is formed between the sealing plate and the scraper to supply the steam spray pipe to spray high-temperature and high-pressure steam on the side wall of the furnace body. During the downward movement, the scraper will scrape the grease whose temperature has been reduced by high temperature downward to improve the cleaning effect of the side wall.

[0026] The utility model has the following advantages:

[0027] In the utility model, the heating coil is used to raise the temperature, and the heat is transferred from the outside to the inside. At the same time, the heater arranged around the central axis of the inner furnace is used to raise the temperature, and the heat is transferred from the center of the furnace body to the outside, so as to quickly heat the edible oil in the furnace body and improve the heating efficiency of the edible oil.

[0028] The furnace cover is lifted by the first lifting component, so that the heater leaves the furnace body, and then it is convenient to clean the inside of the furnace body. The furnace body is flipped by the flipping component, so that it is convenient for the staff to clean and overhaul the furnace body.

[0029] High-pressure steam is sprayed onto the side wall of the furnace body through the steam spray pipe. Under the action of the high-temperature steam, the viscosity of the grease attached to the side wall is reduced and it flows downward. At the same time, under the action of the high-pressure steam, the grease is driven downward, so as to realize the cleaning of the side wall of the furnace body and reduce the labor intensity.

[0030] When the furnace body is working, the steam spray pipe can be hidden in the furnace cover, so as to avoid polluting the edible oil. The edible oil is blocked by the sealing plate, so as to protect the steam spray pipe hidden in the furnace cover and prevent the edible oil from splashing and attaching to the steam spray pipe.

[0031] When the first lifting component drives the steam spray pipe and the sealing plate to move downward together, the connecting pin rod is driven to move together until the lower step surface of the top of the connecting pin rod contacts the upper surface of the first step, and then the scraper is driven to move downward. At this time, a height difference is formed between the sealing plate and the scraper for the steam spray pipe to spray high-temperature and high-pressure steam onto the side wall of the furnace body. During the downward movement, the scraper will scrape the grease with reduced temperature downward to improve the cleaning effect of the side wall. Description of the Drawings

[0048] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0049] In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0050] As described in the background art, existing oil refining equipment usually heats edible oil through a gas heater at the bottom or heating coils wrapped on the outside during oil refining. However, in the above heating methods, heat is transferred from the outside to the inside, resulting in low heating efficiency.

[0051] Embodiment 1:

[0052] Therefore, in order to solve the above technical problems of the prior art, this embodiment hereby proposes an oil refining furnace, as Figure 1 shown, the oil refining furnace includes:

[0053] A furnace body 200, as Figure 2 shown, the furnace body 200 includes an inner furnace 210 and an outer furnace 230. The outer furnace 230 wraps around the outside of the inner furnace 210, forming an interlayer between the outer furnace and the inner furnace, and a heating coil 220 is wound in this interlayer;

[0054] A heater 500, several of these heaters 500 are arranged equiangularly around the central axis of the inner furnace 210 inside the inner furnace.

[0055] In this embodiment, the heating coil is used to increase the temperature, transferring heat from the outside to the inside. At the same time, the heaters arranged around the central axis of the inner furnace increase the temperature, transferring heat from the center of the furnace body to the outside, thereby quickly heating the edible oil in the furnace body.

[0056] Through the above solution, the heating efficiency of the edible oil is improved, and the rapid heating of the edible oil is achieved.

[0057] In this embodiment, as Figure 1 shown, the oil refining furnace may further include:

[0058] A furnace cover 300, the furnace cover 300 is sealed at the top opening of the furnace body 200, and several of the heaters are fixedly installed on the furnace cover 300.

[0059] A first lifting assembly 400, the above-mentioned furnace cover 300 is fixedly installed on the first lifting assembly, and the furnace cover is driven to move linearly vertically by the first lifting assembly.

[0060] The heater is fixedly installed on the furnace cover, and the furnace cover is lifted by the first lifting assembly 400, so that the heater leaves the furnace body, thereby facilitating the cleaning of the inside of the furnace body.

[0061] In this embodiment, the above-mentioned first lifting assembly 400 may be as Figure 3 shown, and may include:

[0062] A fixed frame body 410, the fixed frame body 410 is fixed on the ground, and a first power device 430 is fixedly installed on the top of the fixed frame body 410;

[0063] Lifting frame 420, which is arranged on the front side of the fixed frame 410 and keeps relative sliding with the fixed frame 410. The lifting frame is connected to the first power device through a transmission mechanism, and is driven by the first power device to slide vertically. The above-mentioned furnace cover is fixed on the lifting frame.

[0064] In this embodiment, the above-mentioned transmission mechanism includes, but is not limited to, a sprocket transmission mechanism, a pulley transmission mechanism or other transmission mechanisms that can realize the height adjustment of the lifting frame. Of course, the transmission mechanism may not be used, and devices such as cylinders, electric cylinders, and hydraulic cylinders that can directly lift and lower the lifting can be directly used.

[0065] In addition, the connection method between the above-mentioned lifting frame and the fixed frame can be as Figure 1 shown. Two sets of guide wheels 440 are arranged on the connection side between the lifting frame and the fixed frame. The two sets of guide wheels 440 sandwich the columns of the fixed frame, so that the guide wheels can roll along the extension direction of the columns. Of course, in addition to the above method, the slidable connection between the lifting frame and the fixed frame can also be realized by the ways of guide rail-slider and guide rod-slider.

[0066] In this embodiment, the oil refining furnace may further include a flipping assembly 100. The above-mentioned furnace body is installed on the flipping assembly 100, and the furnace body can be driven to rotate through the flipping assembly, so that the opening of the furnace body facing vertically upward moves to a position inclined downward.

[0067] The furnace body is flipped through the flipping assembly, and the opening of the furnace body is rotated from the state facing vertically upward to the state moving to an inclined downward state, so as to facilitate the staff to clean and repair the furnace body.

[0068] In this embodiment, the above-mentioned flipping assembly 100 can be as Figure 4 shown. The flipping assembly may include a mounting frame body 110. A rotating shaft 120 is arranged on the upper part of the mounting frame body 110, and the rotating shaft is fixedly connected to the side of the furnace body, including connection methods such as welding, fusion welding, bolt connection, riveting, etc.;

[0069] A worm gear 140 is installed on one of the rotating shafts, and a worm 130 meshing with the worm gear is also installed on the mounting frame body 110. The worm is connected to the second power device installed on the mounting frame body. The second power device includes, but is not limited to, devices such as motors and rotary cylinders that can make the worm rotate.

[0070] Embodiment 2:

[0071] Due to the certain viscosity of the edible oil itself, after the oil refining is completed, a small amount of edible oil will adhere to the inner wall of the furnace body and is difficult to clean. Especially for the side wall, since it has a certain angle with the ground, usually vertical, the staff needs to place the spraying device sideways against the side wall so that the spraying device can spray the cleaning liquid directly at the inner wall. However, due to the large size of the furnace body, the staff needs to frequently change positions for the cleaning operation, resulting in a relatively high labor intensity. At the same time, the traditional cleaning method is to clean the inner wall of the furnace body by manually spraying water. However, because water and oil are immiscible, it is difficult to clean the edible oil adhering to the inner wall completely. There is also a method of directly using a cleaning liquid and using the emulsifying effect of the cleaning liquid to wash away the edible oil. However, this method still requires subsequent cleaning with water, which is troublesome to operate.

[0072] Therefore, in order to solve the above technical problems in the prior art, this embodiment makes improvements on the basis of Embodiment 1, as Figure 5 shown, the above-mentioned oil refining furnace may further include

[0073] a second lifting assembly 600;

[0074] a cleaning assembly 700, which is driven by the second lifting assembly 600 to move linearly vertically to clean the grease on the side wall of the inner furnace;

[0075] As Figure 6 shown, among them, the cleaning assembly 700 includes a steam spray pipe 710, which is arranged around the inner side of the inner furnace. An air outlet nozzle is provided on one side of the steam spray pipe close to the side wall of the inner furnace, and the steam spray pipe is communicated with a high-pressure steam source.

[0076] This embodiment is for cleaning the side wall of the furnace body, that is, the inner wall perpendicular to the ground in the furnace body. In this embodiment, high-pressure steam is sprayed onto the side wall of the furnace body through the steam spray pipe. Under the action of the high-temperature steam, the viscosity of the grease adhering to the side wall is reduced, and the fluidity of the edible oil is enhanced, so that it flows downward under the action of gravity. At the same time, under the action of the high-pressure steam, the grease can be driven downward, thus realizing the cleaning of the side wall of the furnace body and reducing the labor intensity. Finally, the bottom of the oil refining furnace can be manually sprayed and cleaned through a hot water spray gun, realizing the efficient cleaning of the inner wall of the furnace body.

[0077] In this embodiment, as Figure 7 shown, a notch matching the steam spray pipe is provided on the lower surface of the furnace cover corresponding to the steam spray pipe, and the steam spray pipe passes in and out of the furnace cover through this notch.

[0078] When the furnace body is working, the steam spray pipe can be hidden inside the furnace cover, thus avoiding contamination of the edible oil.

[0079] A sealing plate 750 can also be provided below the steam spray pipe. When the steam spray pipe is received inside the furnace cover, the lower surface of the sealing plate is flush with the lower surface of the furnace cover.

[0080] The cooking oil is blocked by a sealing plate to protect the steam nozzle hidden in the stove lid and prevent the cooking oil from splashing and adhering to the steam nozzle.

[0081] In this embodiment, as Figure 7 shown, the cleaning assembly may further include a scraping plate 740. The scraping plate 740 is arranged around the steam nozzle and moves together with the steam nozzle. The outer side of the scraping plate contacts the inner side wall of the inner furnace. The scraping plate cooperates with the sealing plate to seal the notch.

[0082] A first step is provided on the side of the scraping plate close to the sealing plate, and a second step is provided on the side of the sealing plate close to the scraping plate. The first step and the second step cooperate with each other for sealing;

[0083] The cleaning assembly further includes a connecting pin rod 720. The connecting pin rod passes through the first step and the second step and slides relative to the scraping plate.

[0084] As Figure 8 shown, when the first lifting assembly drives the steam nozzle and the sealing plate to move downward together, it drives the connecting pin rod to move together until the lower step surface of the top of the connecting pin rod contacts the upper surface of the first step, and then drives the scraping plate to move downward. At this time, a height difference is formed between the sealing plate and the scraping plate for the steam nozzle to spray high-temperature and high-pressure steam onto the side wall of the furnace body. During the downward movement, the scraping plate will scrape the oil reduced by high temperature downward to improve the cleaning effect of the side wall.

[0085] In this embodiment, the bottom end of the above-mentioned connecting pin rod is fixedly connected to the lower surface of the second step, and the outer side of the top end protrudes outward to form a limiting portion that can be stuck on the upper surface of the first step.

[0086] Of course, in addition to the above-mentioned connecting pin rod, a connecting spring can also be used to connect the first step and the second step.

[0087] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
