Description

Technical Field

[0001] This utility model relates to the field of coconut oil production technology, specifically to a high-efficiency extraction device used in coconut oil production. Background Technology

[0002] Coconut oil is a natural plant oil extracted from mature coconut meat. It is rich in medium-chain fatty acids and vitamins, and has high nutritional value and a unique flavor. To retain the active ingredients to the maximum extent, edible coconut oil is often produced using a cold-pressing process (the temperature is usually controlled below 55℃). The screw press is the core equipment in the cold-pressing process, which mechanically squeezes the coconut meat through a screw shaft to achieve continuous oil extraction.

[0003] Patent CN207256937U discloses a screw oil press, comprising an upper hopper and a lower press. The hopper contains a feeding device. The press includes a drive motor, a reducer, a screw shaft, and a pressing chamber fitted around the screw shaft. A feeding hopper connected to the hopper is fitted around the front end of the screw shaft. This feeding hopper is fixedly connected to the reducer. A maintenance opening with a sealing plate is located at the bottom of the feeding hopper. The screw shaft is coaxial with the reducer's output shaft. The hopper comprises an upper cylindrical section and a lower conical section connected together. A horizontally placed cross-shaped support frame is located inside the cylindrical section, on which the feeding device is mounted. The feeding device includes an upper feeding motor and a lower feeding hinge shaft, the lower end of which extends into the feeding hopper. The maintenance opening at the bottom of the feeding hopper facilitates inspection and maintenance during use.

[0004] However, the oil presses described above still have the following problems: during the pressing process, impurities such as coconut meat powder and debris will be discharged from the oil outlet along with the oil, causing the crude oil to become cloudy. A separate filtration process needs to be set up after pressing, which not only increases the cost of equipment, but also easily causes oil oxidation and reduces the quality of the oil due to untimely filtration. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency extraction device for coconut oil production, which integrates an oil filter at the bottom of the oil press to improve the extraction efficiency of coconut oil.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency extraction device for coconut oil production, comprising a screw oil press, an oil receiving tank located below the oil outlet at the bottom of the screw oil press, a support frame connected to the outside of the oil receiving tank, support plates fixedly connected to both ends of the support frame, two symmetrically arranged oil chambers located at the top of the oil receiving tank, several oil filter holes extending through the sides of the two oil chambers that are far apart from each other, a sliding groove located at the bottom of the support frame, the oil receiving tank being slidably connected to the sliding groove, an oil receiving trough extending through the middle of the top of the sliding groove, the oil receiving trough being located below the oil removal port at the bottom of the screw oil press, a movable component connected to one side of the oil receiving tank, the movable component being connected to two support plates, and two pressure filter components connected to the top of the support frame, the two pressure filter components being respectively matched with the two oil chambers.

[0007] Furthermore, two through holes are opened through the top of the chute. The two through holes are located on both sides of the oil receiving trough. The two pressure filter components squeeze and filter the oil collected in the two oil chambers through the two through holes.

[0008] Furthermore, the filter press assembly includes a lifting rod and a pressure plate. Both ends of the lifting rod are fixedly connected to electric push rods. The telescopic ends of the two electric push rods extend vertically downward and are fixedly connected to the support frame. Several connecting rods are fixedly connected to the bottom of the lifting rod. The connecting rods pass downward through the perforation and are fixedly connected to the pressure plate. The outer wall of the pressure plate is slidably connected to the oil cavity.

[0009] Furthermore, the top of the chute has two slots, which are connected to two perforations respectively, and two pressure plates are located in the two slots respectively.

[0010] Furthermore, support grooves are provided at both ends of the chute, and support bars are fixedly connected to both ends of the oil tank. The two support bars are slidably connected to the two support grooves respectively.

[0011] Furthermore, oil collection hoppers are fixedly connected to both sides of the oil receiving tank. Each oil collection hopper has a connecting port on the side closest to the oil receiving tank. The connecting port is connected to several adjacent oil filter holes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 5A high-efficiency extraction device for coconut oil production includes a screw oil press 1. An oil receiving tank 2 is located below the oil outlet at the bottom of the screw oil press 1. A support frame 3 is connected to the outside of the oil receiving tank 2. Support plates 4 are fixedly connected to both ends of the support frame 3. Two symmetrically arranged oil chambers 201 are located at the top of the oil receiving tank 2. Several oil filter holes 202 are opened through the sides of the two oil chambers 201 that are far apart from each other. A sliding groove 301 is opened at the bottom of the support frame 3. The oil receiving tank 2 is slidably connected to the sliding groove 301. An oil receiving trough 302 is opened through the middle of the top of the sliding groove 301. The oil receiving trough 302 is located below the oil removal port at the bottom of the screw oil press 1. A moving component 6 is connected to one side of the oil receiving tank 2. The moving component 6 is connected to the two support plates 4. Two pressure filter components 5 are connected to the top of the support frame 3. The two pressure filter components 5 are respectively matched with the two oil chambers 201.

[0018] The main improvement of this invention lies in enhancing the oil extraction effect, such as... Figures 1 to 5 As shown, the high-efficiency extraction device for coconut oil production in this invention, during use, moves any one of the oil chambers 201 on the oil receiving tank 2 to the position of the oil receiving trough 302 via the moving component 6. This allows the oil extracted by the screw oil press 1 to drip from the oil receiving trough 302 into the oil chamber 201 for collection. Simultaneously, the oil can be filtered through the oil filter holes 202 on the side of the oil chamber 201, allowing clean oil to be discharged from the oil chamber 201. An oil drum can be placed at the bottom of the oil receiving tank 2 to collect the clean oil, reducing the need for subsequent oil filtration and minimizing the oil loss that may occur during oil transfer. Oxidation improves oil extraction efficiency and collection quality. As the oil filter 202 continues to filter, the filtration efficiency gradually decreases. When a large amount of oil is collected in the oil chamber 201, the other oil chamber 201 can be moved below the oil receiving tank 302 by the moving component 6 to continue collecting oil. The oil in the full oil chamber 201 is then squeezed by the pressure filter component 5, which makes the oil in the oil chamber 201 quickly squeezed and filtered. When there are a lot of impurities filtered in the two oil chambers 201, the oil chamber 201 can be moved below the concave oil receiving tank 302 and the internal impurities can be cleaned. Then, the oil is filtered again.

[0019] like Figures 1 to 5 As shown, two through holes 303 are formed at the top of the chute 301. The two through holes 303 are located on both sides of the oil receiving groove 302. The two filter press assemblies 5 squeeze and filter the oil collected in the two oil chambers 201 through the two through holes 303. The filter press assembly 5 can be moved down from the through holes 303 at the top of the support frame 3, thereby squeezing and filtering the oil in the oil chamber 201 inside the support frame 3.

[0020] like Figures 1 to 5As shown, the filter press assembly 5 includes a lifting rod 51 and a pressure plate 52. Both ends of the lifting rod 51 are fixedly connected to electric actuators 53. The telescopic ends of both electric actuators 53 extend vertically downwards and are fixedly connected to the support frame 3. Several connecting rods 54 are fixedly connected to the bottom of the lifting rod 51. These connecting rods 54 pass downwards through the through-hole 303 and are fixedly connected to the pressure plate 52. The outer wall of the pressure plate 52 is slidably connected to the oil chamber 201. The two electric actuators 53 are synchronously controlled by the same controller, causing the lifting rod 51 to move downwards and, through the multiple connecting rods 54, to press the pressure plate 52 into the oil chamber 201, creating a squeezing force on the oil in the oil chamber 201, thereby accelerating the discharge of oil from the filter hole 202.

[0021] like Figures 1 to 5 As shown, the top of the chute 301 has two plate grooves 304, which are connected to two through holes 303 respectively. Two pressure plates 52 are located in the two plate grooves 304 respectively. When the pressure plates 52 are not used to squeeze and filter the oil in the oil cavity 201, they can be moved upward and stored in the plate grooves 304, so that the oil receiving tank 2 can move smoothly laterally in the chute 301.

[0022] like Figures 1 to 5 As shown, both ends of the slide groove 301 are provided with support grooves 305, and both ends of the oil receiving tank 2 are fixedly connected with support bars 21. The two support bars 21 are slidably connected to the two support grooves 305 respectively. When the oil receiving tank 2 moves laterally in the slide groove 301, the connection between the support bars 21 and the support grooves 305 allows the oil receiving tank 2 to be stably supported and moved inside the support frame 3.

[0023] like Figures 1 to 5 As shown, oil collecting hoppers 7 are fixedly connected to both sides of the oil receiving tank 2. Each oil collecting hopper 7 has a connecting port 701 on the side closest to the oil receiving tank 2. The connecting port 701 connects to several adjacent oil filter holes 202. The bottom of each oil collecting hopper 7 has an oil drain port 702 connected to the connecting port 701. During the pressure filtration operation, the oil collecting hoppers 7 prevent oil from splashing out of the oil filter holes 202, allowing the oil to flow downwards within the oil collecting hoppers 7 and be discharged through the bottom oil drain port 702. An oil drum can be placed below the oil drain port 702 at the bottom of the two oil collecting hoppers 7 to smoothly collect the clean oil.

[0024] like Figure 1 and Figure 2As shown, the moving component 6 includes a U-shaped frame 61 and two telescopic members 62. The two ends of the U-shaped frame 61 are fixedly connected to two support plates 4, respectively. The two telescopic members 62 are fixedly connected to the two ends of the U-shaped frame 61, respectively. The telescopic ends of both telescopic members 62 pass through the U-shaped frame 61 and are fixedly connected to the adjacent oil collection hopper 7. The U-shaped frame 61 supports the two telescopic members 62. The two telescopic members 62 can be cylinders, electric actuators, or hydraulic cylinders, and are controlled by the same controller to synchronously drive the oil collection hopper 7 and the oil receiving tank 2 to reciprocate within the slide groove 301 of the support frame 3, completing the switching operation of the two oil chambers 201.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
