Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature refining production of animal fats, and specifically to an animal fat refining device and its use method. Background Art

[0002] Animal fats refer to the fats extracted from chicken and its fat parts. During the production and processing, through the way of high-temperature heating, relatively high-purity animal fats are obtained.

[0003] For example, the "High-temperature Evaporation Tank for Chicken Fat Production" with the publication number CN220618843U includes a high-temperature evaporation tank housing. In the chamber, a loading box for loading chicken bellies is installed through a push-pull assembly. The loading box generates chicken fat in the storage chamber through the evaporation chamber. A top cover is installed on the top surface of the loading box. On one side of the top surface of the high-temperature evaporation tank housing, a first feed port is fixedly connected. On the top surface of the top cover, a second feed port for inputting chicken bellies in cooperation with the first feed port is opened. In the middle of the top surface of the top cover, a servo reduction motor is installed. The output shaft of the servo reduction motor longitudinally penetrates the top cover and is fixedly connected with a dragging and rotating assembly that can hook the chicken belly and drag it to rotate to assist in generating chicken fat.

[0004] However, in the prior art, there are some surface-active substances in animal fats. During the high-temperature refining process, these substances will cause the animal fats to produce foam. When the water in the animal fats turns into water vapor and escapes, it will also be wrapped in these foams, resulting in an increase in foam. In addition, too fast refining speed will also exacerbate the generation of foam. Excessive foam poses a danger of overflowing the refining equipment, causing losses of animal fats. Moreover, the foam will affect the normal progress of refining and reduce the refining efficiency because the foam occupies the refining space, reducing the effective space actually used for animal fat refining. Summary of the Invention

[0018] A using method of an animal fat refining device

[0019] S1. Import a large amount of animal fat into the refining tank. Use a hoisting device to cover the defoaming component on the refining tank. Then connect the electric heating base to an external power supply. Melt the solid fat in the refining tank by generating high temperature. When the liquid fat is separated out, the foam will float on the liquid surface.

[0020] S2. When the liquid fat is separated out, the first reduction motor drives the vertical rod. The vertical rod drives the rotating rod. The push block at the end of the rotating rod is used to push the strip-shaped frame. The strip-shaped frame pushes the gear through the toothed plate.

[0021] S3. The gear drives the driving wheel through a cylinder, and the driving wheel then drives the first driven wheel and the second driven wheel simultaneously through a transmission belt, achieving the purpose of driving the first defoaming belt and the second defoaming belt. The triangular cutting strips at the edges of the first defoaming belt and the second defoaming belt can achieve the purpose of cutting the foam through high-speed friction with the foam.

[0022] S4. During the steaming process, the third reduction motor drives the fan blades, which will stir the liquid flow towards the first defoaming belt, and the second reduction motor will also drive the stirring rod through the belt transmission assembly to continuously stir the solid fat until the animal fat is completely released after the processing is completed.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. In the present invention, a horizontal first defoaming belt and a vertical second defoaming belt are provided. When refining oil at high temperature, the first defoaming belt and the vertical second defoaming belt will rotate at high speed, and the triangular cutting strips at their edges are used to cut the foam, thereby reducing the amount of foam on the liquid surface and solving the problem of excessive foam. During the cutting process, the first scraping plate and the second scraping plate can continuously scrape the foam from other positions off the liquid surface and send it to the vicinity of the second defoaming belt for cutting, thereby improving the defoaming efficiency and ensuring that the foam everywhere in the device can be processed, avoiding the problem that the foam will affect the normal progress of refining and reduce the refining efficiency. After the foam is removed, more liquid surface can be exposed, which can solve the problem of the reduction of the effective space for animal fat refining.

[0025] 2. In the present invention, the position of the first driven wheel and the second driven wheel is determined by setting the extension plate and the support plate. When defoaming, the first reduction motor drives the vertical rod, and the purpose of pushing the gear is achieved by driving the toothed plate to move back and forth. Since the toothed plate moves back and forth, the driving wheel is in a state of rotating back and forth, so that the rotation directions of the first defoaming belt and the second defoaming belt are also in a changing state, thereby avoiding the generation of eddy currents. Combined with the use of the fan blades and the stirring rod, the solid fat is fully stirred, thereby improving the efficiency of oil refining and avoiding the problem that the fat accumulates together and cannot effectively absorb heat.

[0026] 3. In the present invention, the separation frame is placed on the positioning convex strip for filtering foam. During the generation of foam, the foam can only pass through the through holes of the separation frame, thereby avoiding the situation where the solid fat comes into contact with the defoaming component. Openings are provided on the sides of the first scraping plate and the second scraping plate. When the first scraping plate and the second scraping plate move towards the end of the separation frame, the foam along the way can be pushed into the first scraping plate and the second scraping plate. Subsequently, during the process of the first scraping plate and the second scraping plate moving towards the second defoaming belt, the partition plate can play a role in gathering the foam and preventing the foam from moving out of the first scraping plate and the second scraping plate.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: Refer to Figure 1 and Figure 2 As shown: An animal fat refining device includes a refining tank 1. The refining tank 1 includes a defoaming component 2. An electric heating base 13 is fixedly connected to the bottom of the refining tank 1. An oil outlet pipe 14 is fixedly communicated with one end of the refining tank 1. The top of the defoaming component 2 is fixedly connected with a top cover 3. The defoaming component 2 includes a baffle 201, a first defoaming belt 233, a second defoaming belt 210, a separation frame 207, a first scraping plate 205 and a second scraping plate 206. The baffle 201 is vertically arranged along the edge of the refining tank 1 and forms a sealed space with the top cover 3 at the top of the refining tank 1. The oil outlet pipe 14 communicated with the bottom of the refining tank 1 is used to discharge liquid animal fat. A exhaust pipe 5 for discharging water vapor is communicated with the side of the top cover 3. When in use, after the electric heating base 13 is powered on, it heats the solid fat in the refining tank 1. The water vapor generated when the solid fat melts will be discharged from the exhaust pipe 5. Since the boiling point of animal fat is lower than that of water, the melted liquid fat will gather at the bottom of the refining tank 1, so as to achieve the purpose of only leaving animal fat. This is the prior art and will not be elaborated here. The refining temperatures of different animal fats are shown in the following table:

[0042] Chicken fat Duck fat Beef fat Pork fat Mutton fat 80℃-100℃ 85℃-105℃ 120℃-150℃ 100℃-120℃ 110℃-130℃

[0043] During the process of refining animal fats, since the density of the foam is less than that of the fat, the foam will float on the surface of the fat during the refining process. At this time, the defoaming assembly 2 located above the refining tank 1 can handle the foam on the liquid surface. The first defoaming belt 233 and the second defoaming belt 210 in the defoaming assembly 2 can cut the foam and release the air inside, thereby reducing the number of foams. The separation frame 207 is used to limit the position of the solid fat, restricting the solid fat below the liquid surface to avoid contact with the first defoaming belt 233 and the second defoaming belt 210. The first scraping plate 205 and the second scraping plate 206 are used to drive the foam close to the second defoaming belt 210, aiming to improve the defoaming efficiency.

[0044] According to Figure 2 As shown, the first defoaming belt 233 and the second defoaming belt 210 are perpendicularly arranged. Among them, the first defoaming belt 233 is horizontally arranged inside the refining tank 1, and the second defoaming belt 210 is vertically arranged inside the refining tank 1. The two first defoaming belts 233 are symmetrically arranged along the horizontal center line of the refining tank 1. There are multiple triangular cutting strips at the edges of the two first defoaming belts 233 and at the edges of the second defoaming belt 210. The second defoaming belt 210 is symmetrically arranged along the vertical center line of the refining tank 1, and the two second defoaming belts 210 are respectively located at both ends of the first defoaming belt 233. The first defoaming belt 233 and the second defoaming belt 210 are perpendicularly arranged to handle the foam at different positions. Among them, the first defoaming belt 233 is horizontally arranged to handle the foam from a direction perpendicular to the second defoaming belt 210, so as to expand the cleaning area. When the triangular cutting strips at the edges of the first defoaming belt 233 and at the edges of the second defoaming belt 210 come into contact with the foam, they can generate greater pressure and also generate friction with the foam, ensuring that foams of various volumes can be effectively processed.

[0045] According to Figure 2As shown, the first scraping plate 205 is located on one side of one of the second defoaming belts 210, and the second scraping plate 206 is located on one side of the other second defoaming belt 210. The distance between the first scraping plate 205 and the second scraping plate 206 is three-fifths of the length of the separation frame 207. Through holes 230 are provided at the bottoms of both the first scraping plate 205 and the second scraping plate 206. Both the first scraping plate 205 and the second scraping plate 206 are above the separation frame 207. During the operation of the defoaming assembly 2, both the first scraping plate 205 and the second scraping plate 206 will move back and forth on the separation frame 207, sending the foam to the second defoaming belt 210, thereby ensuring that the foam everywhere in the refining tank 1 can be processed, avoiding the problem that the foam will affect the normal progress of refining and reduce the refining efficiency, and after the foam is removed, more liquid surfaces can be exposed, which can solve the problem of the reduction of the effective space for animal fat refining;

[0046] According to Figure 2 As shown, positioning ridges 11 are fixedly installed on the inner walls at both ends of the refining tank 1. The separation frame 207 is clamped on the upper surface of the positioning ridges 11. Limiting plates 202 are fixedly installed on the inner walls on both sides of the refining tank 1. The height of the limiting plates 202 is flush with the height of the separation frame 207. A gap greater than the thickness of the first scraping plate 205 is left between both the first defoaming belt 233 and the second defoaming belt 210 and the separation frame 207. The separation frame 207 is stuck on the positioning ridges 11, thereby determining the height of the solid fat. The limiting plates 202 can determine the effective range of the liquid surface. Since the foam floats on the liquid surface and the liquid surface is at the separation frame 207, the liquid surface is in contact with the lower surface of the limiting plates 202. Blocked by the liquid, the foam will be concentrated near the separation frame 207.

[0047] In this embodiment, during use, a large amount of animal fat is introduced into the refining tank 1, and then the defoaming assembly 2 is installed. The baffle 201 and the top cover 3 enclose the top space of the refining tank 1. Then, the electric heating base 13 continuously heats the refining tank 1 to melt the solid fat inside the refining tank 1 into a liquid state. When the liquid fat precipitates, the foam will float on the liquid surface, and the limiting plates 202 will limit the foam at the separation frame 207, and the separation frame 207 prevents the solid fat from contacting the first defoaming belt 233 and the second defoaming belt 210;

[0048] During the refining process, the first defoaming belt 233 and the second defoaming belt 210 will rotate. When the triangular cutting strips at their edges contact the foam, they can scrape the foam, and during this process, the first scraping plate 205 and the second scraping plate 206 will also move back and forth on the separation frame 207, pushing the foam on the liquid surface to the vicinity of the second defoaming belt 210 for cutting treatment.

[0049] Embodiment Two: According to Figure 2 、Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , both ends of the first defoaming belt 233 and both ends of the second defoaming belt 210 are movably connected with limiting blocks 209. A vertically upward transmission rod 208 is fixedly connected to the top of the limiting block 209. A first driven wheel 223 is fixedly connected to the top of the transmission rod 208 corresponding to the first defoaming belt 233, and a second driven wheel 217 is fixedly connected to the top of the transmission rod 208 corresponding to the second defoaming belt 210. The first driven wheel 223 and the second driven wheel 217 correspond to the first defoaming belt 233 and the second defoaming belt 210 respectively;

[0050] The first driven wheel 223 and the second driven wheel 217 are symmetrically arranged in an H shape. The first driven wheel 223 is located at the corner of the H shape, and the second driven wheel 217 is located at the end of the H shape. A transmission belt 219 is synchronously meshed and connected between the edge of the first driven wheel 223 and the edge of the second driven wheel 217. A fan blade 8 is rotatably installed on one side of the refining tank 1, and a third reduction motor 12 is fixedly connected to the center of the fan blade 8. The symmetrical structure of the H shape can ensure the overall balance state of the structure and avoid imbalance. Moreover, both the first driven wheel 223 and the second driven wheel 217 are meshed and connected with the transmission belt 219, and the whole rotates at the same angular velocity;

[0051] A driving wheel 221 is meshed and connected to the middle section of the transmission belt 219. A cylinder 220 is fixedly connected to the upper surface of the driving wheel 221, a gear 222 is fixedly connected to the top of the cylinder 220, a hollow block 214 is sleeved on the outer wall of the cylinder 220, a horizontally arranged docking rod 211 is fixedly connected to one side of the hollow block 214, the other end of the docking rod 211 is fixedly connected to the baffle 201, a connecting rod 231 is fixedly connected to the bottom of the docking rod 211, and the connecting rod 231 is fixedly connected to the separation frame 207. The driving wheel 221 is connected to the cylinder 220. During use, the gear 222 drives the driving wheel 221 through the cylinder 220, so as to drive the transmission belt 219;

[0052] On both sides of the bottom of the hollow block 214, extension plates 215 are fixedly connected. A gap 224 is provided at the junction of the hollow block 214 and the extension plates 215. The driving wheel 221 is located inside the gap 224. The driving wheel 221 and the first driven wheel 223 are both rotatably installed on the upper surface of the extension plates 215. Support plates 216 are fixedly connected to both ends of the extension plates 215. The second driven wheel 217 is rotatably installed at both ends of the support plates 216. A positioning plate 225 is fixedly installed on the upper surface of the docking rod 211. A toothed plate 203 is slidably connected to the upper surface of the positioning plate 225. One side of the toothed plate 203 is meshed with the gear 222. A trapezoidal protrusion 226 is fixedly installed on the lower surface of the toothed plate 203. The toothed plate 203 is slidably connected to the positioning plate 225 through the trapezoidal protrusion 226.

[0053] In this embodiment, during use, the movement of the toothed plate 203 will drive the gear 222, and the rotation of the gear 222 will drive the driving wheel 221 at the bottom of the cylinder 220, so as to achieve the purpose of driving the conveyor belt 219. The cylinder 220 is installed inside the hollow block 214. The gap 224 between the extension plates 215 and the hollow block 214 is used to accommodate the driving wheel 221. The positions of the driving wheel 221 and the first driven wheel 223 are determined by the extension plates 215, and the overall layout is horizontal, determining the positions of the two first defoaming belts 233.

[0054] The toothed plate 203 is slidably connected to the positioning plate 225 through the trapezoidal protrusion 226. The presence of the trapezoidal protrusion 226 can not only determine the movement route of the toothed plate 203 but also prevent the toothed plate 203 from detaching from the positioning plate 225.

[0055] The second driven wheel 217 is installed on the support plates 216 at both ends of the extension plates 215, determining the positions of the two second defoaming belts 210. When the driving wheel 221 drives the conveyor belt 219, the conveyor belt 219 will drive the first driven wheel 223 and the second driven wheel 217 at the same time. The first driven wheel 223 and the second driven wheel 217 then drive the transmission rod 208 to achieve the purpose of driving the first defoaming belt 233 and the second defoaming belt 210. The positions of the first defoaming belt 233 and the second defoaming belt 210 are determined by the limiting block 209.

[0056] During the process of refining oil, the third reduction motor 12 will drive the fan blade 8, and the fan blade 8 will agitate the liquid, so that the liquid in the refining tank 1 is always in a flowing state. And during the process of liquid flow, the foam above it will contact the first defoaming belt 233. A filter screen for separating solid fat and the fan blade 8 is installed under the limiting plate 202.

[0057] The docking rod 211 on the side of the hollow block 214 is fixedly connected to the baffle 201, serving the purpose of determining the position of the cylinder 220.

The stirring rod 10 is rotatably installed on the inner wall of the refining tank 1. Both ends of the toothed plate 203 are fixedly connected with bent rods 204. The other ends of the two bent rods 204 are respectively fixedly connected between a first scraping plate 205 and a second scraping plate 206. An opening 229 is formed on one side of the first scraping plate 205 and one side of the second scraping plate 206. A partition plate 232 is fixedly installed inside the opening 229. The inclination angle of the partition plate 232 is greater than 30 degrees and less than 45 degrees.

[0059] In this embodiment, the push block 227 in the strip-shaped frame 218 above the toothed plate 203 is rotatably connected with the rotating rod 228. During use, the first reduction motor 4 drives the rotating rod 228 through the vertical rod 213. The rotating rod 228 drives the strip-shaped frame 218 through the push block 227 to drive the toothed plate 203. The toothed plate 203 will move back and forth once when the rotating rod 228 rotates one week. The position of the vertical rod 213 is determined by the docking block 212;

[0060] During the refining process, the exhaust valve 9 on the top cover 3 can discharge the gas in the refining tank 1 in real time to ensure that the air pressure in the refining tank 1 will not be too high. The exhaust pipe 5 is used to discharge the water vapor during the process of heating the fat;

[0061] The second reduction motor 6 drives the stirring rod 10 in the refining tank 1 through the belt drive assembly 7. The rotation of the stirring rod 10 will continuously stir the solid fat, making it heat more evenly and ensuring the refining efficiency;

[0062] The first scraping plate 205 and the second scraping plate 206 are respectively connected to the toothed plate 203 through two bent rods 204. During the movement of the toothed plate 203, the first scraping plate 205 and the second scraping plate 206 will be driven synchronously. When the first scraping plate 205 and the second scraping plate 206 move towards the end of the separation frame 207, the foam along the way can pass through the opening 229 and enter the first scraping plate 205 and the second scraping plate 206. Subsequently, during the movement of the first scraping plate 205 and the second scraping plate 206 towards the second defoaming zone 210, the inclined partition plate 232 can play a role in gathering the foam and preventing the foam from moving out of the first scraping plate 205 and the second scraping plate 206.

[0063] Usage method and working principle of this device: First, a large amount of animal fat is introduced into the refining tank 1. The defoaming assembly 2 is installed on the refining tank 1 using the lifting device. Subsequently, the electric heating base 13 is connected to an external power source, and the solid fat in the refining tank 1 is melted by generating high temperature. When the liquid fat is separated out, the foam will float on the liquid surface, and the limiting plate 202 will limit the foam at the separation frame 207. During the refining process, the water vapor will be discharged from the exhaust pipe 5, and the liquid oil mainly accumulates at the bottom of the refining tank 1. The foam will float on the liquid surface. As the liquid level rises, the oil outlet pipe 14 at the bottom of the refining tank 1 is opened to discharge a part of the liquid oil, and the liquid level is controlled at the separation frame 207 until all the liquid fat is completely evaporated. During the refining process, the third reduction motor 12 drives the fan blade 8, which will stir the liquid oil to flow towards the first defoaming zone 233, and the second reduction motor 6 will also drive the stirring rod 10 through the belt drive assembly 7 to continuously stir the solid fat;

[0064] When the liquid fat is separated out, the first reduction motor 4 drives the vertical rod 213, drives the rotating rod 228 through the vertical rod 213, and uses the push block 227 at the end of the rotating rod 228 to push the strip-shaped frame 218. The strip-shaped frame 218 drives the toothed plate 203 to move along the direction of the positioning plate 225. During the movement of the toothed plate 203, it will push the gear 222;

[0065] The gear 222 drives the driving wheel 221 through the cylinder 220, and the driving wheel 221 drives the first driven wheel 223 and the second driven wheel 217 simultaneously through the transmission belt 219. During the rotation of the first driven wheel 223 and the second driven wheel 217, the first defoaming zone 233 and the second defoaming zone 210 on the limiting block 209 at the bottom of the transmission rod 208 rotate at the same speed;

[0066] During the rotation of the first defoaming belt 233 and the second defoaming belt 210, the triangular cutting strips at their edges can rub against the foam at high speed, achieving the purpose of cutting the foam. Moreover, as the toothed plate 203 moves, the first scraping plate 205 and the second scraping plate 206 will continuously bring the foam on the separation frame 207 to the vicinity of the second defoaming belt 210.

[0067] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
