Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of natural product extraction, in particular to a small cell wall flexible stripping essential oil extraction equipment. BACKGROUND

[0002] In the field of natural product extraction, citrus essential oil is widely used in food, daily chemical and other industries due to its flavor and functionality, and its extraction effect is largely dependent on the pretreatment of raw materials. The pretreatment process needs to realize the flexible stripping of citrus peel through the cooperation of material conveying and peeling operation, so as to fully release the essential oil components and avoid the introduction of impurities caused by fruit flesh damage. With the increasing demand for small-scale processing, small citrus pretreatment equipment has become a necessity, and the core performance of such equipment depends on whether the conveying and peeling can be effectively coordinated.

[0003] The existing small citrus pretreatment equipment generally uses a grinding roller with fixed speed for peeling, and uses a conveyor belt or a screw rod to convey the raw materials. This design has the following obvious problems: on the one hand, the peeling component has a fixed speed, which has poor adaptability to citrus with different characteristics. When processing citrus with thin and soft peel, the fruit flesh is easily damaged due to improper grinding force control; when processing citrus with thick and hard peel, it is difficult to completely peel due to insufficient grinding force, resulting in essential oil components remaining in the peel. On the other hand, the speed of the conveying component cannot be adjusted, and it is difficult to match the peeling rhythm. When using a conveyor belt to convey, the raw materials are prone to accumulation or uneven spacing, and some raw materials are sent away without being fully contacted with the peeling component, resulting in incomplete peeling; when using a screw rod to convey, the raw materials have a fixed residence time in the peeling area, and too short residence time will result in incomplete peeling, and too long residence time will cause excessive grinding, further damaging the fruit flesh cells and increasing the impurity content. These problems make the pretreatment effect of the existing equipment unstable, and cannot adapt to citrus raw materials with different characteristics, which cannot meet the needs of small-scale processing for stable pretreatment quality.

DETAILED DESCRIPTION

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, one embodiment of the present invention provides a small-scale cell wall flexible peeling essential oil extraction device, comprising a supporting mechanism 1, a sealing mechanism 3, a circulating pushing mechanism 7, and a peeling mechanism 8. The supporting mechanism 1 provides a stable foundation support for the entire device. The sealing mechanism 3 is assembled on the top of the supporting mechanism 1, and its interior forms a closed citrus pretreatment working chamber. The circulating pushing mechanism 7 and the peeling mechanism 8 are both located in this working chamber, and the two work together to achieve directional conveying and flexible peeling of the citrus.

[0035] The load-bearing mechanism 1 includes a base frame 11. The base frame 11 is a high-strength frame structure, welded from carbon steel, which can accommodate the overall weight of the equipment and the load during the citrus processing, providing a stable reference for the installation of various functional components, while ensuring that the equipment is at a working height that meets the operational requirements.

[0036] The sealing mechanism 3 includes a housing 31. The housing 31, as the main structure of the equipment, is made of stainless steel, possessing corrosion resistance and easy-to-clean properties, making it suitable for food-grade pretreatment scenarios. The housing 31 is bolted to the top of the base frame 11, and the working chamber formed inside provides a closed space for citrus processing.

[0037] The sealing mechanism 3 also includes a feeding guide frame 33. The feeding guide frame 33 is fixed to the inside of the housing 31 near the citrus input end by bolts and has an inclined feeding structure. Its upper end is used to connect to the subsequent feeding component, and its lower end extends to the starting end of the circulating feeding mechanism 7, which can guide the citrus raw material smoothly into the circulating feeding mechanism 7 and avoid the raw material hitting the inner wall of the housing 31 and causing damage.

[0038] The sealing mechanism 3 also includes a tension adjustment component 32. The tension adjustment component 32 is installed on the inner wall of the housing 31 by adjusting bolts and is set corresponding to the driven sprocket 72 of the circulating pusher mechanism 7. Its movable end abuts against the bearing seat of the driven sprocket 72. By turning the adjusting bolts, the installation position of the driven sprocket 72 can be changed, thereby adjusting the tightness of the transmission components of the circulating pusher mechanism 7 to ensure stable transmission without slippage.

[0039] The circulating pushing mechanism 7 comprises a driving sprocket 71 and a driven sprocket 72. The driving sprocket 71 and the driven sprocket 72 are rotatably installed at two ends inside the shell 31 through bearing fitting rotating shafts, and the center axes of the two are at the same horizontal level, which guarantees the smooth operation of the transmission components.

[0040] The circulating pushing mechanism 7 further comprises a chain 73 and a pushing plate 74. The chain 73 is sleeved outside the driving sprocket 71 and the driven sprocket 72, forming a closed-loop transmission structure. The pushing plate 74 is uniformly welded and fixed along the circumference of the chain 73, and its height is adapted to the height of the inner wall of the working chamber of the shell 31, which can adhere to the chamber wall to push the citrus, avoiding the leakage of raw materials from between the pushing plate 74 and the chamber wall. The orientation of the pushing plate 74 is consistent with the transmission direction of the chain 73, which is used to drive the citrus to move directionally inside the shell 31.

[0041] The peeling mechanism 8 comprises side plates 82. The side plates 82 are two rectangular steel plates, which are fixedly installed on the two side walls inside the shell 31 through inclined bolts. Both of the two side plates 82 are inclined inward, which is used to position and limit the subsequent peeling components.

[0042] The peeling mechanism 8 further comprises at least two groups of peeling components 81. The peeling component 81 comprises a transmission shaft 811, the two ends of which are rotatably installed on the top of the chassis 11 through bearing seats on the opposite sides of the two side plates 82. The center axis is parallel to the conveying direction of the chain 73, which ensures that the moving direction of the citrus is adapted to the peeling direction.

[0043] The peeling component 81 further comprises a positioning rod 812 and a peeling cylinder 813. The positioning rod 812 is uniformly welded and fixed on the outer periphery of the transmission shaft 811 along the axial direction of the transmission shaft 811, forming a ring-shaped array, which can uniformly transmit the torque of the transmission shaft 811. The peeling cylinder 813 is made of flexible wear-resistant material, which is sleeved outside the transmission shaft 811 through the positioning rod 812 and fixed with the positioning rod 812, avoiding the damage of rigid grinding to the fruit pulp. Uniform gaps are reserved between the peeling cylinders 813 of adjacent peeling components 81, which are adapted to the falling demand of citrus peel scraps.

[0044] During operation, the citrus raw materials are guided into the starting end of the circulating pushing mechanism 7 through the feeding guide 33. The external power source drives the driving sprocket 71 to rotate, and the driving sprocket 71 drives the driven sprocket 72 to rotate synchronously through the chain 73. The pushing plate 74 on the chain 73 pushes the citrus to move along the inside of the shell 31 to the peeling mechanism 8.

[0045] At the same time, the external power source drives the transmission shaft 811 to rotate, and the transmission shaft 811 drives the peeling cylinder 813 to rotate synchronously through the positioning rod 812. The citrus is in contact with the peeling cylinder 813 under the pushing of the pushing plate 74, and the flexible grinding surface of the peeling cylinder 813 grinds and peels the citrus skin.

[0046] If the chain 73 becomes loose during the process, the adjusting bolt of the tension adjustment component 32 can be turned to push the driven sprocket 72 to move and tighten the chain 73. The peeled citrus peel fragments fall through the gap between the adjacent grinding cylinders 813, and the citrus body that has been ground continues to move with the pusher plate 74 to the end of the housing 31 for discharge.

[0047] Example 2

[0048] like Figures 1 to 6 As shown, one embodiment of the present invention provides a small-scale flexible cell wall peeling essential oil extraction device, which, based on the first embodiment, further includes a first drive mechanism 5, a second drive mechanism 9, a reverse rolling gear and a control box 2, to realize independent regulation and coordinated control of the circulating pushing speed and the peeling speed, and to adapt to the processing needs of citrus fruits with different characteristics.

[0049] The first drive mechanism 5 is a chain drive assembly driven by a speed-regulating motor, which is fixedly installed on the left side of the base frame 11 by a bracket. Its output end is connected to the drive sprocket 71 of the circulating pusher mechanism 7. The chain drive is adapted to the drive sprocket 71 to ensure stable power transmission. It is used to drive the drive sprocket 71 to rotate, thereby adjusting the pushing speed of the circulating pusher mechanism 7.

[0050] The second drive mechanism 9 is a gear transmission assembly driven by a speed-regulating motor, which is fixedly mounted on the right side of the base frame 11 by a bracket. Its output end is connected to the input end of the reverse hobbing gear, providing power support for the peeling mechanism 8, and the peeling intensity can be adjusted according to the characteristics of the citrus peel.

[0051] The reverse roller gear adopts a helical gear meshing structure and is fixed to the right side of the base frame 11 corresponding to the position of the second drive mechanism 9 by a bracket. Its output end is connected to the drive shaft 811 of the peeling mechanism 8, which can change the power transmission direction of the second drive mechanism 9, so that the rotation direction of the drive shaft 811 is opposite to the rotation direction of the drive sprocket 71, thereby enhancing the relative friction between the citrus and the peeling cylinder 813 and improving the peeling efficiency.

[0052] The control box 2 is bolted to the outer front wall of the housing 31. Its outer shell is designed to be waterproof and dustproof, meeting the cleaning requirements of the processing environment. The control box 2 integrates a controller, a speed regulation module, and a speed feedback module. The controller has stable logic control capabilities.

[0053] The speed regulation module is electrically connected to the speed-regulating motors of the first drive mechanism 5 and the second drive mechanism 9, respectively, and is used to receive controller commands and adjust the motor speed. The speed feedback module is connected to the output shaft of the motors of the first drive mechanism 5 and the second drive mechanism 9, respectively. It collects speed signals through encoders, can monitor the actual motor speed in real time, and feeds the speed signals back to the controller.

[0054] The operation panel of the control box 2 is provided with a display screen and an adjusting button, and the operation panel is electrically connected with the controller to realize man-machine interaction. The display screen is used for displaying real-time rotating speed, working time and other parameters, and the adjusting button is used for setting target rotating speed, starting or stopping the equipment.

[0055] During work, the operator sets the pushing rotating speed of the first driving mechanism 5 and the peeling rotating speed of the second driving mechanism 9 through the adjusting button of the operation panel of the control box 2. After receiving the setting instruction, the controller drives the first driving mechanism 5 to drive the driving sprocket 71 to rotate through the rotating speed adjusting module, and drives the second driving mechanism 9 to drive the transmission shaft 811 to rotate through the reverse gear.

[0056] The rotating speed feedback module collects the actual rotating speeds of the first driving mechanism 5 and the second driving mechanism 9 in real time, and feeds back signals to the controller. If there is a deviation between the actual rotating speed and the setting rotating speed, the controller corrects the motor output through the rotating speed adjusting module to realize closed-loop control.

[0057] When processing citrus fruits with thin and soft skins, the corresponding pushing rotating speed and peeling rotating speed can be adjusted to reduce the peeling intensity and avoid damage to the fruit pulp; when processing citrus fruits with thick and hard skins, the corresponding rotating speed parameters can be adjusted to prolong the peeling time and ensure complete peeling.

[0058] Embodiment three

[0059] As shown in Figures 1 to 6 An embodiment provided by the present application: a small cell wall flexible stripping essential oil extraction equipment, further comprising a discharging structure, a top cover 4 and a drip pipe 6 on the basis of embodiment two, realizing classification collection of citrus bodies and skin scraps, improving feeding convenience and solvent mixing effect, and perfecting the pretreatment function of the equipment.

[0060] The discharging structure comprises a discharging groove 12. The discharging groove 12 is a groove body made of stainless steel, which is installed on the top of the chassis 11 corresponding to the position below the end of the shell 31 by welding. The top opening of the discharging groove 12 is matched in size with the opening at the bottom of the shell 31 and is in communication, which is used for collecting citrus skin scraps falling from the gap of the peeling cylinder 813 and subsequent mixed solvents, and the bottom end is provided with a discharge port to guide the skin scrap mixture to be discharged directionally to the subsequent separation equipment.

[0061] The discharging structure further comprises a discharging guide frame 13. The discharging guide frame 13 is a plate-shaped structure made of stainless steel, which is fixed on the top of the chassis 11 corresponding to the position of the end of the shell 31 on the left side by bolts. One end of the discharging guide frame 13 extends to the inside of the shell 31 corresponding to the position below the end of the circulating pushing mechanism 7, and the other end extends to the outside of the chassis 11, which is used for guiding the citrus bodies after peeling to be stably discharged to the subsequent fruit pulp processing equipment.

[0062] The top cover 4 is a stainless steel cover plate that can be detachably installed on the top of the housing 31 by bolts. A sealing gasket is provided at the connection between the top cover 4 and the housing 31 to enhance the sealing of the working chamber and prevent external dust from mixing in and solvent from evaporating.

[0063] The top cover 4 has a funnel-shaped feed inlet 41, which is located directly above the feed guide frame 33 inside the housing 31. Its funnel structure facilitates feeding operations and prevents raw materials from spilling. The inner wall of the feed inlet 41 is coated with an anti-slip and wear-resistant coating to reduce bumps and slips during the falling of citrus fruits.

[0064] The drip tube 6 is a round tube made of food-grade material. It is fixed to the bottom of the top cover 4 by a tube clamp and is arranged horizontally along the length of the shell 31 and located above the circulating feeding mechanism 7. Multiple drip holes are evenly opened on the drip tube 6 along its length to ensure that the solvent evenly covers the citrus fruits being processed.

[0065] The inlet of the drip tube 6 is connected to an external solvent storage tank via a flexible tube. The inlet of the drip tube 6 is also equipped with a manually controlled valve. The operator can adjust the drip rate of the solvent by turning the valve to create a suitable mixing ratio between the extraction solvent and the ground citrus peel fragments, thereby improving the efficiency of essential oil extraction.

[0066] During operation, the operator puts the citrus raw materials to be processed into the feed port 41 of the top cover 4. The raw materials slide down the anti-slip coating on the inner wall of the feed port 41 and are guided into the circulating push mechanism 7 by the feed guide frame 33.

[0067] After the equipment is started, the valve of the drip tube 6 is opened to the set opening degree, and the extraction solvent is evenly sprayed onto the surface of the citrus fruit during the movement through the drip hole. After the solvent comes into contact with the citrus peel, it falls into the discharge trough 12 along with the peel peel and peel scraps through the gap between the grinding cylinders 813, and is discharged into the essential oil separation equipment through the discharge port at the bottom of the discharge trough 12.

[0068] The peeled citrus fruit is pushed to the end of the housing 31 by the pusher plate 74, falls into the discharge guide frame 13 and slides out along its inclined surface, and enters the subsequent pulp processing process.

[0069] After the equipment has finished operating, the fixing bolts of the top cover 4 can be removed, and the top cover 4 can be removed to clean and maintain the inside of the housing 31, the circulating material pushing mechanism 7 and the grinding mechanism 8 to ensure hygiene for the next use.
