Description

Technical Field

[0001] This invention belongs to the field of dried Sichuan pepper pressing, specifically a spiral-type dried Sichuan pepper pressing device and its process. Background Technology

[0002] Sichuan pepper, a traditional Chinese spice and oil crop, produces oil with a unique aroma and medicinal value, which is widely used in food, medicine, and daily chemical industries. Currently, the extraction of dried Sichuan pepper oil mostly adopts the spiral pressing process. This process has become a commonly used method in large-scale production due to its advantages such as simple operation, low production cost, and good preservation of the inherent flavor of Sichuan pepper oil.

[0003] However, existing spiral-type dry pepper pressing devices still have some problems in practical applications: After the existing screw press device finishes pressing the dried peppercorns, a large amount of residual oil that has not been fully pressed out will still be mixed in with the peppercorn residue. Directly discharging the peppercorn residue with oil will result in a low oil recovery rate of the dried peppercorn raw material, causing a waste of resources.

[0015] A process for a spiral-type dry pepper pressing device, the process comprising the following steps: S1. Preliminary preparation: Place an oil storage assembly at the discharge end of the oil guide plate; S2. Pressing for oil extraction: Dried peppercorns are put into the hopper of the pressing component. The spiral auger pushes the raw material to compress it step by step. The squeezed oil is guided into the oil storage component for collection through the oil guide plate. S3. Pepper residue receiving: After pressing, the pepper residue falls into the guide plate.

[0016] The beneficial effects of this invention are as follows: The present invention discloses a spiral-type dry pepper pressing device and its process, which sets up a three-station rotating material cylinder and filter cylinder structure. The pepper residue discharged after pressing is introduced into the filter cylinder of the corresponding station. The pepper residue is then subjected to secondary treatment through a centrifugal oil removal process. The centrifugal force generated by the rotation of the filter cylinder is used to completely separate the residual oil that was not fully pressed out inside the pepper residue. The separated pepper oil is discharged and collected through a guide plate and an oil discharge trough. This avoids the resource waste caused by the direct discharge of pepper residue with oil in traditional pressing devices, and significantly improves the oil recovery rate of dry pepper raw materials. Through the design of the drive and filter components, the system automatically switches between three stations: pepper residue collection, centrifugal oil removal, and residue discharge, eliminating the need for manual transfer of pepper residue or switching of separation equipment. During centrifugal oil removal, the filter cylinder and drive block rotate synchronously, and the oil is naturally separated through the filter holes and discharged through the guide structure without manual intervention. When switching stations, the coordinated action of the telescopic rod and drive motor quickly completes the rotation and positioning of the support plate, enabling the orderly switching of the three cylinders. This allows the pepper residue collection, oil removal, and discharge processes to proceed continuously, significantly shortening the separation cycle. Attached Figure Description

[0030] A process for a spiral-type dry pepper pressing device, the process comprising the following steps: S1. Preliminary preparation: Place the oil storage component at the discharge end of the oil guide plate 3; S2, pressing for oil extraction: Dried peppercorns are put into the hopper of pressing component 2, and the spiral auger pushes the raw material to compress it step by step. The squeezed oil is introduced into the oil storage component for collection through the oil guide plate 3. S3, Pepper Residue Receiving: After pressing, the pepper residue falls into the guide plate 4. Start the telescopic rod 44 to open the discharge end of the guide plate 4 and send the pepper residue into the filter cylinder 521 in the corresponding work station material cylinder 52. After the filling is completed, close the discharge end. S4. Workstation rotation and deoiling: Switch to workstation rotation mode and drive the support plate 51 to rotate to complete the workstation switching; switch to centrifugal deoiling mode and drive the filter cartridge 521 to rotate. The corresponding workstation centrifuges the pepper residue for deoiling, and the oil is discharged and collected through the guide plate 525 and the oil discharge trough 54. At the same time, the corresponding workstation continues to receive material. S5, Pepper Residue Discharge: After the corresponding workstation has completed the oil removal, the workstation is rotated to the residue discharge workstation again. The automatic discharge valve 524 is opened, and the pepper residue is discharged through the residue discharge pipe 55. S6. Continuous operation: Repeat the above steps of receiving material, rotating, degreasing, and slag discharge, and use three material cylinders 52 for continuous operation in a cycle; S7. Operation complete: Stop feeding, finish processing the remaining pepper residue, shut down all parts, clean the equipment and remove the grease and pepper residue.

[0031] Specifically, An oil storage component is placed at the discharge end of the oil guide plate 3 to receive the pressed-out pepper oil; The dried Sichuan peppercorns are fed into the hopper of the pressing component 2. Under the rotation of the spiral auger inside, the dried Sichuan peppercorns are sent into the pressing area. In the pressing section, the pitch of the spiral auger gradually decreases, while the diameter of the spiral shaft gradually increases, so that the channel space where the dried Sichuan peppercorns are located is continuously and progressively compressed, thereby generating greater and greater mechanical pressure on the peppercorns. Under high pressure, the oil in the dried Sichuan peppercorns is squeezed out and collected in the oil guide plate 3. The oil guide plate 3 then guides the Sichuan peppercorn oil into the oil storage component for collection. The pressed pepper residue cannot continue forward due to the resistance of the screen and the end cone. It is eventually discharged from the machine through the gap between the end of the screen and the cone and falls into the guide plate 4 for discharge.

[0032] It should be noted that the oil drain port 551 is used to drain the separated Sichuan pepper oil.

[0033] When the guide plate 4 discharges pepper residue, the telescopic rod 44 is activated to push the push plate 43 outward, and the valve plate 41 is moved away through the connecting rod 42, so that the discharge end of the guide plate 4 is opened and the pepper residue can be discharged; similarly, the telescopic rod 44 is used to pull the push plate 43, and the valve plate 41 is pushed into the guide plate 4 through the connecting rod 42, so that the discharge end of the guide plate 4 is closed.

[0034] like Figure 15 As shown, the positions of the three material cylinders 52 are labeled a, b, and c, respectively. The material cylinder 52 at position a corresponds to the discharge end of the guide plate 4 and is used to collect pepper residue. The material cylinder 52 at position b is used for the centrifugal oil extraction process. When the filter cylinder 521 rotates to centrifuge and extract oil from the pepper residue inside, the pepper oil is thrown through the filter holes on the outside of the filter cylinder 521 between the filter cylinder 521 and the material cylinder 52, and falls onto the guide plate 525. The guide plate 525 then directs the pepper oil through... The oil is discharged through the oil drain trough 54, flowing into the support platform 5 and then out through the oil drain port 551. The material cylinder 52 at position c is directly above the slag discharge pipe 55. The filter cylinder 521 is connected to the oil baffle ring 552 via the drive block 516 at its bottom. When the automatic discharge valve 524 is opened, the pepper residue on the discharge pipe 523 is discharged through the filter cylinder 521 into the oil baffle ring 552, and then discharged through the slag discharge pipe 55, thus completing the discharge of the pepper residue. It should be noted that the function of the oil baffle ring 552 is to prevent the separated pepper oil from flowing into the slag discharge pipe 55.

[0035] Principles of oil filter assembly and drive assembly: In the default state, the rectangular connecting block 566 is inserted into the rectangular groove 5110, and the rectangular connecting block 566 does not contact the rectangular groove 513. The connecting post 565 is placed in the rectangular groove 513. Since the connecting post 565 is a columnar design, it will not drive the support plate 51 to rotate when it rotates. Therefore, under the driving action of the drive motor 568, the gear 519 rotates and drives the gear ring 517 to rotate, causing the drive block 516 and the filter cartridge 521 to rotate. This is state A. It should be noted that when the gear 519 rotates, the support plate 51 remains stationary. In order to ensure its accurate position, the pin of the telescopic rod 512 is inserted into the locking block 511 to lock and fix the position of the support plate 51.

[0036] When driving the support plate 51, first activate the telescopic rod 3 564 to pull down the sliding block 567, causing the movable plate 56 to move down, so that the rectangular connecting block 566 moves out of the rectangular groove 2 5110 and is locked into the rectangular groove 1 513 at the bottom of the support plate 51. At this time, the drive motor 568 is connected to the support plate 51, and the telescopic rod 2 512 is activated to disengage its pin from the locking block 511, stopping the locking of the support plate 51. The drive motor 568 can then drive the support plate 51 to rotate to change the position of the three material cylinders 52. This is state B.

[0037] It should be noted that state A is the process of driving the filter cartridge 521 to rotate, and state B is the process of changing workstations.

[0038] Open the discharge end of the guide plate 4 to inject pepper residue into the material cylinder 52 at position a. The pepper residue is introduced into the filter cylinder 521 through the second hopper 53 and the first hopper 522. After injecting a sufficient amount of pepper residue into the filter cylinder 521, adjust the component to state B, so that the material cylinder 52 at position a moves to position b. Then adjust the component to state A to perform centrifugal deoiling of the pepper residue. At the same time, the material cylinder 52 at position c moves to position a to collect the pepper residue. After collecting, adjust the component to state B, so that the collected material cylinder 52 moves to position b. At this time, the material cylinder 52 at position b moves to position c to perform the pepper residue discharge operation. Repeat the above process to rotate the material cylinders 52 at the three positions, thereby realizing the collection, deoiling and discharge of pepper residue. It should be noted that when gear 519 rotates, it will synchronously drive the three filter cylinders 521 to rotate synchronously. To ensure that the filter cylinder 521 at position a is fed smoothly, a guide head of the corresponding specification needs to be installed at the discharge end of the guide plate 4 according to the actual specifications of the equipment. Through the guiding action of the guide head, the pepper residue falls accurately from the center of the filter cylinder 521 into the cylinder, avoiding the residue from shifting due to the reciprocating rotation of the filter cylinder 521, and ensuring smooth feeding. The filter cylinder 521 at position c performs the discharge process in the reciprocating rotation state. The centrifugal force of rotation can be used to assist the discharge of the residue, which greatly improves the discharge efficiency and thoroughness of the pepper residue.

[0039] It should be noted that when the support platform 5 rotates, the guide block 514 at its bottom will rotate within the guide ring 515. The guide block 514 and the guide ring 515 can guide the rotation of the support platform 5 and ensure its rotational stability. At the same time, the guide ring 515 is located on the inner bottom wall of the support platform 5, and the oil drain port 551 is located on the outer periphery of the guide ring 515. The guide ring 515 can block the pepper oil discharged through the oil drain groove 54 and prevent it from flowing through the middle position inside the support platform 5 into the various components at its bottom, thus preventing oil leakage.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
