Description

Technical Field

[0001] The invention relates to the technical field of oil extraction, and in particular to an extraction process of emu wormwood essence milk. Background Art

[0002] Emu oil is an ideal choice for cosmetic raw materials because of its rich essential fatty acids, antioxidant ingredients, skin compatibility, non-irritation, protective effects, biodegradability, high purity and multiple application potentials. It can provide natural and effective skin and hair care in a variety of cosmetics such as skin creams, facial masks, essences, hair care products, etc. Emu oil is mostly extracted from emu fat through oil extraction equipment. The oil extraction equipment includes extraction equipment for solvent injection, mixing, heating and extraction, filtration and separation equipment for removing solid residues in the extract and achieving solid-liquid separation, solvent recovery equipment for recovering and recycling the solvent used in the extraction process, drying and purification equipment for evaporating the solvent in the extract to obtain pure oil and further purification treatment, and control systems and safety and environmental protection systems for accurately controlling various parameters of the extraction process including temperature, pressure, flow, etc.

[0003] In the prior art, the crushed fat is put into the extraction part and heated by the extraction part to produce oil. However, the position of the heating element in the extraction part is fixed, and some fat is close to the heating element, so it is heated and melted first to produce oil. The other part of the fat is farther away from the heating element than the fat close to the heating element. When the fat close to the heating element begins to melt, it does not melt. The fat close to the heating element melts after a period of time. When it is completely melted, the fat close to the element has been completely melted for a period of time. In this process, fat that is heated for a long time may appear inside the equipment. If the fat melting time is too long, the oil will be heated for a long time. After heating, the color may darken and the transparency may decrease, which is a sign of deterioration in the quality of the oil. Some nutrients in the fat, such as vitamin E and other antioxidants, may also be destroyed during the long heating process, thereby reducing the nutritional value of the oil. Long-term heating may cause the decomposition of fat molecules. The structural change of the oil will affect its physical properties, such as fluidity and viscosity, and affect its application in subsequent cosmetics production, producing free fatty acids and other decomposition products, which may further affect the flavor and nutritional value of the oil, and may produce harmful substances, such as trans fatty acids and polymers, which may have adverse effects on health.

[0041] Beneficial Effects

[0042] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0043] The present invention is provided with a suction head, and the jet valve is started to release inert gas to the inner wall of the tank cover, and the air pressure in the space above the suction head increases. Since the environment with higher air pressure will exert greater pressure on the suction head, while there is almost no pressure on the vacuum side, the suction head will be subjected to a net force from the high-pressure side to the vacuum side, and this force will cause the suction head to move rapidly toward the vacuum side until the lower surface of the filter screen contacts the unmelted emu fat. The suction head and the filter screen moving between the liquid emu fat will stop under the action of the resistance, and at this time the transmission pipeline is in an open state, and the vacuum inside the tank and the pressure inside the separation tank are in a state of 0.1% to 0.1%. Under the combined effect of the force difference and the siphon formed between the heating tank and the separation tank by the connecting pipe composed of the suction head, the connecting pipe and the transmission pipe, the fat melted into liquid in the tank body will enter the separation tank through the suction head, the connecting pipe and the transmission pipe. As the melting of solid fat decreases, the friction between fats decreases, and the resistance to the suction head also gradually decreases. Therefore, as the fat melts, the suction head will gradually penetrate into the tank body, and then continuously absorb the upper layer of liquid fat that has completed the solid-liquid conversion, avoiding problems such as nutrient loss caused by its long stay in the heating environment;

[0044] The present invention is provided with a discharge piece and a connecting piece. The pressing block can contact the discharge piece only when the filter screen moves to a relatively lower position. When the two telescopic rods are contracted to the minimum size, the bottom end of the pressing block is close to the top of the slide slot. With the subsequent downward movement, the pressing block can move inside the slide slot. The inside of the slide slot is slidably connected with a movable block, and the inclined edge of the movable block fits with the inclined edge of the pressing block. With the downward movement of the pressing block, the movable block can be squeezed to move away from the center position of the valve body. After the squeezing rod moves, the butterfly valve formed by the valve body and the valve cover opens, and the lower layer of grease mixed with solid oil residue flows out of the valve, and then the lower layer of liquid grease that has completed the solid-liquid conversion is transmitted to the secondary filter tank, so as to avoid problems such as nutrient loss caused by its staying in a heated environment for a long time.

[0045] The present invention is provided with a secondary filtering tank. When the connecting piece is contracted to the minimum state, the pushing plate has the maximum extrusion displacement on the arc block. In this process, the valve seat is opened, and the lower layer of crude oil and oil residue gradually flow into the secondary filtering tank. The crude oil carried in the collecting box gradually increases, and the connecting layer also stretches to a certain position. The stretching of the connecting layer drives the tooth plate to move downward, and the movement of the tooth plate drives the gear meshing with it to rotate. The transmission ratio between the tooth plate and the gear is 1:3. The rotation of the gear drives the eccentric wheel to rotate reciprocally. The change in radius of the rotation of the eccentric wheel and the bottom end of the feeler rod drives the feeler rod to move reciprocally up and down. The feeler rod applies an interval thrust to the bottom end of the filter screen through the pushing rod, so that the filter screen vibrates. The vibration of the filter screen can vibrate the debris intercepted at its lower position, so that the debris can fall into the liquid grease and fall into the secondary filtering tank with the grease, so as to realize the effective removal of the oil residue.

[0081] S6, wormwood leaf extraction: the processed wormwood leaf is mixed with a solvent and soaked for a period of time to fully dissolve the active ingredients, and the soaked wormwood leaf solution is heated to reflux through an extraction tank and maintained for a certain period of time to cycle the extraction process;

[0082] S7, refining the finished product: passing the extract through a filtering device to separate the solid residue and the extract, concentrating the filtered extract to remove the solvent, leaving the concentrated wormwood extract, and drying the concentrated extract to obtain a solid wormwood extract;

[0083] S8. Preparation of essence lotion: first slowly add the processed powder into the heated oil, and after the powder and oil are evenly mixed, perform homogenization. Then add the mixed oil phase into the water phase for emulsification. After the emulsification is completed, perform necessary quality inspections and fill the final product into suitable packaging containers.

[0084] Please pay attention to Figure 1 - Fig.10 In S3, an extraction device is used to extract emu fat, such as Figure 2 and Figure 3As shown, the extraction equipment includes a heating tank 1, a conveying pipeline 2 and a separation tank 3. The heating tank 1 includes a tank body 11. A feed port 15 is provided on the outside of the tank body 11. The staff can convey the crushed raw materials to the tank body 11 through the feed port 15 for vacuuming and smelting. In this process, water molecules and odorous micromolecular volatiles in the raw materials are separated from the raw oil. During smelting, the temperature in the tank body 11 is controlled at 80 to 90 degrees Celsius, and the vacuum degree is -0.03 to -0.08Mpa. After smelting is completed, the oil residue is separated into crude oil and oil residue, and the crude oil in the oil residue is then extracted through the secondary filtering tank 18 arranged at the bottom of the tank body 11. The upper crude oil is transmitted through the transmission pipeline 2, and the lower crude oil is transmitted through the connecting pipe 2 19 arranged outside the secondary filtering tank 18. The outer side of the transmission pipeline 2 can be installed with an oil pump to provide additional power as needed. The other end of the upper crude oil transmission pipeline 2 is inserted into the separation tank 3, and the crude oil enters the separation tank 3 through the transmission pipeline 2. The lower crude oil enters the separation tank 3 through the connecting pipe 2 19 after preliminary filtration. The molten oil directly enters the separation tank 3 without being heated for a long time together with the unmelted fat, and can directly enter the separation tank 3 for further separation and filtration operations.

[0085] refer to Figure 3 and Figure 4 The heating tank 1 also includes a tank cover 12 fixed on the top of the tank body 11. The middle part of the outer surface of the tank cover 12 is fixedly connected to one end of the conveying pipe 2. The middle part of the inner surface of the tank cover 12 is fixedly connected to a connecting pipe 16. The connecting pipe 16 is connected to the conveying pipe 2. The bottom end of the connecting pipe 16 is fixedly connected to a suction head 17. The suction head 17 is set to a funnel shape with a depression in the middle, and a limiting ring is fixedly connected to one side of the suction head 17 close to the bottom end of the tank body 11. The limiting ring of the suction head 17 can slide and seal with the inner wall of the tank body 11. In the initial state, the suction head 17 is located inside the tank cover 12 and fits the inner wall of the tank cover 12.

[0086] refer to Figure 3 , Figure 4 and Figure 5After the emu fat in contact with the heating element is heated for a period of time, the jet valve 13 is activated to spray a fixed amount of gas into the can cover 12. The jet valve 13 is activated to release the inert gas to the inner wall of the can cover 12. The air pressure on the upper surface of the suction head 17 increases, and a pressure difference is formed between the upper and lower surfaces of the suction head 17. The suction head 17 moves downward under the push of the high pressure, and the connecting pipe 16 extends the suction head 17 to move downward and contact the filter screen 4. At this time, since the limiting ring on the side of the suction head 17 is made of flexible material, the limiting ring will expand toward the side of the can body 11 in the vacuum environment, so that the suction head The suction head 17 is close to the filter 4, and the movement of the suction head 17 will drive the filter 4 to move. Since the environment with higher air pressure will exert greater pressure on the suction head 17, and there is almost no pressure on the vacuum side, the suction head 17 will be subjected to a net force from the high pressure side to the vacuum side. This force will cause the suction head 17 to move rapidly toward the vacuum side. In a vacuum, there is no air resistance to slow down the movement of the object, so the object will continue to accelerate until the lower surface of the filter 4 contacts the unmelted emu fat. The chopped emu fat has a greater friction with each other, which will cause the filter 4 and the suction head to move rapidly. The movement of the head 17 creates a large resistance, so the suction head 17 and the filter screen 4 moving between the liquid emu fat will stop under the action of the resistance. At this time, the pushed suction head 17 will also provide pressure for the solid fat. Under high pressure, the raw material cell structure is destroyed, and the fat can be separated from the solid fat tissue, which helps to improve the oil yield. At this time, the transmission pipeline 2 is in an open state, and the vacuum inside the tank body 11 and the pressure difference inside the separation tank 3 and the connecting pipeline composed of the suction head 17, the connecting pipe 16 and the transmission pipeline 2 Under the combined effect of the siphon formed between the heating tank 1 and the separation tank 3, the oil melted into liquid in the tank body 11 will enter the separation tank 3 through the suction head 17, the connecting pipe 16 and the transmission pipe 2. As the melting of the solid fat decreases, the friction between the fats decreases, and the resistance to the suction head 17 also gradually decreases. Therefore, as the fat melts, the suction head 17 will gradually penetrate into the tank body 11, and then continuously absorb the liquid oil that has completed the solid-liquid conversion, thereby avoiding problems such as nutrient loss caused by its staying in the heating environment for a long time.

[0087] refer to Figure 3 , Figure 4 and Figure 5In the initial state, the pressure on both sides of the suction head 17 is the same, and both are in a vacuum state. The suction head 17 fits tightly with the inner wall of the tank cover 12. After the tank body 11 is heated and melted to melt part of the fat for a period of time, the corresponding time jet valve 13 is set by the control system to start, and pressure is applied to the position above the suction head 17. The suction head 17 moves toward the inside of the tank body 11 under the action of the pressure difference, so that the suction head 17 extends into the solid-liquid mixture. At this time, the suction head 17, the connecting pipe 16 and the transmission pipeline 2 constitute a connected pipeline heating tank 1 and separation tank 3. Since the vacuum environment pressure in the heating tank 1 is lower than the pressure environment in the separation tank 3, the liquid fat in the tank body 11 will be poured into the inside of the connected pipeline under the action of the pressure difference. Since the water level in the separation tank 3 is always lower than the water level in the heating tank 1, the liquid will produce a siphon phenomenon, that is, it will continue to flow from the heating tank 1 to the separation tank 3, forming a continuous liquid column, until the filter screen 4 reaches the bottom position, the suction head 17 will continuously absorb the liquid in contact with it, and complete the timely transfer of the upper layer of fat that is gradually melted and converted into liquid.

[0088] Compared with the vacuum oil boiling kettle in the prior art which consumes a lot of energy during operation, especially for heating and maintaining the vacuum state, the present invention only needs to evacuate the inside of the tank body 11 to a suitable vacuum condition after the fat is put in. There is no need to maintain the vacuum environment all the time, and the maintenance and calibration costs are low.

[0089] Since fats with different melting degrees will have different quality changes, suspended solid particles and solid substances that sink to the bottom will appear in the heating space. Large suspended solid particles and solid substances that sink to the bottom will affect the purity and quality of the fat. Refer to 3 and Figure 5 The present invention is provided with a filter screen 4 fitted with the suction head 17. The filter screen 4 can block large suspended solid particles to prevent them from entering the connecting pipe 16 and the transmission pipe 2 and causing blockage in the liquid input process. With the conversion between solid and liquid and the effect of pressure difference, the solid-liquid mixture is in a flowing state, and the suspended solid particles can gradually gather to the edge of the filter screen 4 under the action of liquid impact, reducing the possibility of solid particles breaking and entering the connecting pipe 16 and the transmission pipe 2 under the impact.

[0090] refer to Figure 5 and Figure 6, a plurality of connecting members 5 are fixedly connected to the lower surface of the filter 4, and the connecting member 5 includes a telescopic rod 51 fixedly connected to the lower surface of the filter 4. The filter 4 slides down smoothly under the restriction of the telescopic rod 51, and a pressure plate 52 is fixedly connected to the bottom end of the telescopic rod 51. A push rod 55 is elastically connected to the side of the pressure plate 52. When the connecting member 5 receives the downward pressure from the filter 4, the telescopic rod 51 of the connecting member 5 first contracts and deforms, and a compression spring 53 is elastically connected to the bottom end of the pressure plate 52. When the telescopic rod 51 is contracted to the bottom end, the telescopic rod 51 drives the pressure plate 52 to move downward. The elastic force of the compression spring 53 is greater than the friction force of the telescopic rod 51 sliding and the resistance of the pressure block 54 sliding on the outside of the telescopic rod 51. The bottom end of the compression spring 53 is elastically connected to a pressure block 54, and the pressure block 54 is set to be a 7-shaped plate, and the bottom end of the pressure block 54 is set to be When the other telescopic rod 51 still has space to move, the compression spring 53 will not undergo elastic deformation. When the two telescopic rods 51 are shrunk to the minimum size, the bottom end of the pressing block 54 is close to the top of the discharge piece 6. In the subsequent downward movement, the pressure gradually increases until it is greater than the elastic force of the compression spring 53. At this time, the pressure plate 52 squeezes the compression spring 53, and the compression spring 53 squeezes the pressing block 54, so that the pressing block 54 moves toward the inside of the discharge piece 6 under the restriction of the compression spring 53. Therefore, the pressing block 54 can only contact the discharge piece 6 when the filter screen 4 moves to a relatively lower position.

[0091] like Figure 6 As shown, after the connecting piece 5 changes from an open state to a contracted state, the upper molten fat is absorbed into the separation tank 3 through the suction head 17. After the two telescopic rods 51 of the connecting piece 5 are contracted to the minimum size, the upper layer of fat is transferred. At this time, the remaining fat and oil residue are mixed and temporarily stored in the space between the filter screen 4 and the discharge piece 6. As the compression spring 53 of the connecting piece 5 is deformed, the remaining oil residue fat is processed.

[0092] refer to Fig. 9 , Figure 7 and Figure 8The discharging member 6 includes a valve seat 61 fixedly connected to the bottom end of the telescopic rod 51 at the lower position, and a plurality of slide grooves 63 are provided on the top of the valve seat 61. When the two telescopic rods 51 are retracted to the minimum size, the bottom end of the pressing block 54 is close to the top of the slide groove 63. With the subsequent downward movement, the pressing block 54 can move inside the slide groove 63. The inside of the slide groove 63 is slidably connected with a movable block 64. The bevel of the movable block 64 is in contact with the bevel of the pressing block 54. With the downward movement of the pressing block 54, the movable block 64 can be moved. 4 is squeezed to make it move away from the center of the valve seat 61. The end of the movable block 64 close to the inner wall of the valve seat 61 is fixedly connected with a sealing plate 67. The inner side of the valve seat 61 is rotatably connected with a butterfly plate 62. In the initial state, the sealing plate 67 is engaged with the limiting groove 621 on the side of the butterfly plate 62 to limit the butterfly plate 62. As the movable block 64 moves, the sealing plate 67 that moves synchronously gradually stops engaging with the limiting groove 621. The butterfly plate 62 is connected to the main shaft by the main shaft. The inner wall of the valve seat 61 is rotatably connected. After the butterfly plate 62 is unrestricted, the main shaft drives the butterfly plate 62 to rotate ninety degrees on the inner wall of the valve seat 61 under the rotation of the control system, and the closed valve seat 61 is opened. The remaining grease and oil residue temporarily stored in the space between the filter screen 4 and the discharge piece 6 will enter the secondary filter tank 18 through the opened valve seat 61. With reference to the existing butterfly valve structure, the push plate 65 exists as a starting switch for the valve. After the push plate 65 moves, the valve composed of the valve seat 61 and the butterfly plate 62 is no longer closed. At this time, the valve is opened, and the lower layer of crude oil mixed with solid oil residue flows out of the valve, so as to collect the oil residue containing large particles, avoid large solid particles clogging the pipeline, filter or centrifuge, causing equipment failure and affecting production efficiency, and effectively remove the oil residue that is difficult to separate from the suspended solid particles or precipitated solid matter, so as to avoid their accumulation inside the equipment, causing safety risks such as equipment overheating, fire or explosion.

[0093] refer to Figure 7 , Figure 8 and Fig. 9 , one end of the movable block 64 close to the outer wall of the valve seat 61 is fixedly connected with a push plate 65, and the long rod 66 drives the push plate 65 to move synchronously. The push plate 65 is set to an inclined angle from top to bottom, and the top width is the smallest. When the push plate 65 moves from a position close to the center of the valve seat 61 to a position away from the center of the valve seat 61, the height of the push plate 65 is higher than the height of the valve seat 61. When the filter screen 4 moves to the bottom, the push plate 65 can fit the side of the filter screen 4. The side of the filter screen 4 is tightly fitted with the arc block 42 through the rubber block 41. The push plate 65 is inserted between the filter screen 4 and the arc block 42. As the push plate 65 moves, the arc block 42 is squeezed, so that the arc block 42 is tightly fitted with the inner wall of the tank body 11, such as Fig.10As shown, the purpose of limiting the filter screen 4 is achieved, so that the filter screen 4 and the arc block 42 on its side are no longer in a sliding connection with the inner wall of the tank body 11, and the arc block 42 and the inner wall of the tank body 11 are tightly fitted and the positions of the two are fixed. At this time, the arc block 42 and the side of the filter screen 4 change from being tightly fitted to having a certain gap. Therefore, the filter screen 4 restricted by the rubber block 41 of the flexible material can vibrate within a certain range, which is convenient for effectively removing the oil residue.

[0094] refer to Figure 7 , Figure 8 and Fig. 9 , an eccentric wheel 68 is sleeved on one side of the long rod 66 close to the push plate 65, and a gear 69 is fixedly connected to the side of the eccentric wheel 68. A cylindrical spring is sleeved on the outside of the long rod 66 located inside the valve seat 61, and the cylindrical spring is located in the space between the gear 69 and the movable block 64. In the initial state, the eccentric wheel 68 is in a flat state, and the movement of the movable block 64 drives the long rod 66 to move, and the movement of the long rod 66 drives the eccentric wheel 68 and the gear 69 to move synchronously, until the push plate 65 squeezes the arc block 42, and the eccentric wheel 68 and the gear 69 also move to the corresponding position. At this time, the eccentric wheel A touch rod 611 is arranged above the wheel 68, and the touch rod 611 consists of a cross rod and a ball shaft. The cross rod is arranged above the valve seat 61, and the bottom end of the cross rod is fixedly connected to the ball shaft. The eccentric wheel 68 gradually contacts the ball shaft during its movement. After the push plate 65 moves to the limit position, the lower surface of the ball shaft fits with the surface of the moved eccentric wheel 68, and the gear 69 also moves to a position where it is meshed and connected with the tooth plate 183 of the secondary filter tank 18. A push rod 55 is arranged above the cross rod, and the center line of the push rod 55 coincides with the center line of the cross rod. The connector 5 shrinks to the minimum size. Fig.10 In the state shown, the push rod 55 contacts the upper part of the touch rod 611, and the touch rod 611 moves up and down to drive the push rod 55 to move up and down, and the push rod 55 moves up and down to push the filter screen 4 to move sideways.

[0095] refer to Figure 7 and Figure 8 The secondary filter tank 18 includes a connecting layer 182 elastically connected to the bottom end of the valve seat 61, and a plurality of tooth plates 183 are fixedly connected to the inner side of the connecting layer 182. In the initial state, the connecting layer 182 is in a contracted state, and the tooth plates 183 are meshed and connected with the gear 69. A collecting box 181 is provided at the bottom end of the connecting layer 182, and a filtering layer 184 for filtering the oil residue again is fixedly connected to the inner wall of the collecting box 181. The connecting pipe 19 fixedly connected to the outer wall of the collecting box 181 is flush with the filtering layer 184.

[0096] When the connector 5 is retracted to the minimum state, that is, Fig.10When the position is shown, the push plate 65 has the largest extrusion displacement on the arc block 42. During this process, the valve seat 61 is opened, and the lower layer of crude oil and oil residue gradually flow into the secondary filter tank 18. The crude oil carried in the collecting box 181 gradually increases, and the connecting layer 182 is also stretched to a certain position. The stretching of the connecting layer 182 drives the tooth plate 183 to move downward, and the movement of the tooth plate 183 drives the gear 69 meshing therewith to rotate. The transmission ratio between the tooth plate 183 and the gear 69 is 1:3. The rotation of the gear 69 drives the eccentric wheel 68 to rotate reciprocatingly. The change in radius of the rotation of the eccentric wheel 68 and the bottom end of the feeler rod 611 drives the feeler rod 611 to move up and down reciprocatingly. The feeler rod 611 applies an interval thrust to the bottom end of the filter screen 4 through the push rod 55, so that the filter screen 4 vibrates. The vibration of the filter screen 4 can vibrate the debris intercepted at its lower position, so that the debris can fall into the liquid grease and fall into the secondary filter tank 18 with the grease, so as to realize the effective removal of the oil residue.

[0097] refer to Figure 7 and Figure 8 During the process of opening the valve port, the bottom of the suction head 17 is no longer in a vacuum environment. The entry of external gas increases the air pressure at the bottom of the suction head 17. The temperature and pressure in the closed space are different from those in the external environment. After the space is opened, the length and elastic coefficient of the compression spring 53 will change due to the changes in temperature and pressure. Therefore, the compression spring 53 will vibrate or move slightly, thereby driving the debris on the lower surface of the filter screen 4 to vibrate and make it fall, thereby improving the efficiency of removing oil residue.

[0098] After the oil residue and the lower layer of oil fall into the collecting box 181, open the connecting pipe 19, and the inner wall of the connecting pipe 19 is set to an inclined state to facilitate the rapid flow of liquid oil. After the lower layer of oil is melted, it enters the connecting pipe 19 through the initial filtration of the filter layer 184 and is transmitted to the separation tank 3 along the connecting pipe 19. The upper and lower layers of oil enter the separation tank 3 in batches, and the oil does not need to be heated for a long time. The solid oil residue gradually settles at the bottom of the inner wall of the collecting box 181 as the oil is transmitted. After the lower layer of oil is transmitted, the collecting box 181 shrinks to its initial position. The secondary filter tank 18 is set to a detachable structure, which can be disassembled and cleaned regularly. The device can be disassembled as a whole for cleaning to increase the service life of the device.

[0099] After the oil residue is completely removed, the pressure relief valve above the heating tank 1 opens, and the air pressure above the suction head 17 gradually returns to normal atmospheric pressure. At this time, the connecting pipe 16 is not restricted by pressure, and drives the suction head 17 to move toward the tank cover 12. The suction head 17 no longer applies pressure to the connecting piece 5 through the filter screen 4. The compression spring 53 of the connecting piece 5 and the two telescopic rods 51 are all restored to their initial lengths. Since the elastic force of the compression spring 53 is greater than the elastic force of the telescopic rod 51, during the elastic deformation recovery process of the compression spring 53, the pressure block 54 will be pulled to slide along the outer side of the lower telescopic rod 51 until it returns to its original position, and the pressure block 54 moves out of the slide groove 63. , the movable block 64 recovers the push plate 65 to its original position as the elastic deformation of the cylindrical spring recovers. The pressure relief valve is opened and the control system of the valve seat 61 performs the closing task, controlling the butterfly plate 62 to rotate in the opposite direction until the two overlap. The push plate 65 squeezes and seals the butterfly plate 62 and the valve seat 61 again, and the rubber block 41 returns to its original position. The filter screen 4 and the rubber block 41 return to a state where they can slide on the inner wall of the tank body 11, and return to their original position driven by the overall elastic deformation recovery of the connecting piece 5, that is, the lowest end of the filter screen 4 is slightly higher than the position of the feed port 15, which will not interfere with the feeding process of the fat, and is convenient for the melting treatment of the next batch of fat.
