Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to a fruit oil extraction device. Background Technology

[0002] Sea buckthorn berries have thin skin, soft flesh, and seeds containing a large amount of fruit oil. If they are not crushed sufficiently, the cell walls of the seeds will be difficult to break, and the fruit oil cannot be effectively released. If they are crushed excessively, impurities such as peel and pulp will easily get mixed in, affecting the quality of the fruit oil.

[0003] Current sea buckthorn fruit oil extraction equipment mostly adopts a single crushing method, such as only extrusion or only grinding, which can only achieve preliminary crushing of sea buckthorn fruit and cannot simultaneously meet the dual requirements of breaking the fruit shell and breaking the cell wall of the seed, resulting in a low fruit oil release rate. At the same time, most equipment uses separation methods such as filtration and settling after crushing, which has low separation efficiency and makes it difficult to completely separate the fruit oil from the fine fruit residue. This not only wastes the fruit oil, but also affects the purity of the fruit oil due to the residue of impurities. In view of the shortcomings of the existing technology, this utility model provides a fruit oil extraction device to solve the above problems. Utility Model Content

It integrates a crushing device and a centrifugal device on a frame, configuring the crushing device as a graded structure with a primary extrusion mechanism and a secondary grinding mechanism. Simultaneously, the discharge ports of the centrifugal device and the crushing device are connected, forming an integrated process. The primary extrusion mechanism, through first and second extrusion rollers coated with flexible material, can initially crush the fruit shell and extract some free fruit oil while protecting the sea buckthorn pulp. The secondary grinding mechanism, through first and second grinding rollers with blunt tooth structures, can further knead and crush the fruit seeds, breaking down cell walls to fully release the fruit oil. Finally, the centrifugal device achieves efficient separation of the fruit oil and fruit residue, improving the purity of the fruit oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fruit oil extraction device, comprising a frame, on which a crushing device and a centrifugal device are mounted; the crushing device comprises a feed hopper, a primary extrusion mechanism, and a secondary grinding mechanism;

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This embodiment discloses a fruit oil extraction device, according to the appendix. Figure 1 To be continued Figure 5 As shown, the device includes a frame 1, on which a crushing device 2 and a centrifugal device 3 are mounted. The crushing device 2 includes a feed hopper 21, a primary extrusion mechanism, and a secondary grinding mechanism. The primary extrusion mechanism includes a first extrusion roller 41 and a second extrusion roller 42 driven by a first motor 4 and meshing with each other. The surfaces of the first extrusion roller 41 and the second extrusion roller 42 are covered with a flexible material. The secondary grinding mechanism includes a first grinding roller 51 and a second grinding roller 52 driven by a second motor 5 and meshing with each other. The surfaces of the first grinding roller 51 and the second grinding roller 52 are provided with blunt tooth structures. The feed inlet of the centrifugal device 3 is connected to the discharge outlet of the crushing device 2. The centrifugal device 3 has a drain pipe 31 and a slag discharge gate 32 on its side.

[0025] According to the appendix Figure 2 To be continued Figure 5 As shown, further, the first extrusion roller 41 and the second extrusion roller 42 in the primary extrusion mechanism achieve synchronous opposite rotation through the meshing of the first gear 411 and the second gear 421; when the first motor 4 starts, the power is transmitted through the meshing of the first gear 411 and the second gear 421, driving the first extrusion roller 41 and the second extrusion roller 42 to rotate in opposite directions at the same speed, ensuring uniform extrusion of the input sea buckthorn fruit, and avoiding insufficient extrusion or accumulation of sea buckthorn fruit due to inconsistent roller speeds.

[0026] According to the appendix Figure 3 To be continued Figure 5 As shown, further, the first grinding roller 51 and the second grinding roller 52 in the secondary grinding mechanism achieve synchronous opposite rotation through the meshing third gear 511 and fourth gear 521, and the first grinding roller 51 and the second grinding roller 52 have different rotational speeds; driven by the second motor 5, the third gear 511 and the fourth gear 521 generate different rotational speeds due to the difference in the number of teeth during transmission, so that the first grinding roller 51 and the second grinding roller 52 with blunt tooth structures on their surfaces perform kneading and grinding on the sea buckthorn fruit residue after primary extrusion, which can not only fully break the cell walls of the sea buckthorn fruit to release the fruit oil, but also avoid the sharp structure from damaging the fruit oil components.

[0027] According to the appendix Figure 1 Appendix Figure 3 As shown, the centrifuge device 3 is equipped with a third motor 6 at the bottom, and a drum 61 is provided at the output end of the third motor 6. When the sea buckthorn fruit mixture after secondary grinding enters the drum 61 of the centrifuge device 3, the third motor 6 drives the drum 61 to rotate at high speed. The centrifugal force is used to separate the sea buckthorn fruit oil from the fruit residue in the mixture. The fruit oil will gradually accumulate on the outer side of the inner wall of the drum 61, while the fruit residue will remain in the central area of ​​the drum 61, thus achieving efficient separation of fruit oil and fruit residue.

[0028] According to the appendix Figure 4 As shown, it is particularly important to emphasize that the flexible material covering the surfaces of the first extrusion roller 41 and the second extrusion roller 42 is food-grade silicone or polyurethane. This type of material has good elasticity and wear resistance. When performing primary extrusion on sea buckthorn fruit, it can conform to the shape of the sea buckthorn fruit to achieve full extrusion, while avoiding excessive damage to the sea buckthorn fruit skin and the introduction of impurities. At the same time, the food-grade material can ensure that the extracted sea buckthorn fruit oil meets food safety standards and that no harmful substances are released.

[0029] According to the appendix Figure 1 As shown, it is particularly important to emphasize that the valve 311 installed on the drain pipe 31 on the side of the centrifuge device 3 can precisely control the outflow of sea buckthorn fruit oil. During the centrifugation process, the valve 311 can be closed to allow the fruit oil to fully accumulate in the centrifuge device 3. After the separation is completed, the valve 311 can be opened to discharge and collect the fruit oil, avoiding incomplete separation that could lead to the mixing of fruit residue into the fruit oil. The slag discharge door 32 can be opened after the fruit oil is discharged to discharge the fruit residue remaining in the drum 61, facilitating subsequent cleaning and the next extraction operation.

[0030] Example 1: This example uses fresh sea buckthorn berries as the extraction raw material, combined with... Figure 1 To be continued Figure 5 Detailed explanation of the workflow: The workflow is as follows:

[0031] Raw material input: Fresh sea buckthorn berries are fed into the crushing device 2 through the feed hopper 21. Under the action of gravity, the sea buckthorn berries enter between the first extrusion roller 41 and the second extrusion roller 42 of the primary extrusion mechanism.

[0032] First stage of extrusion: Start the first motor 4, which drives the first extrusion roller 41 to rotate. Through the meshing first gear 411 and second gear 421, the second extrusion roller 42 rotates synchronously in opposite directions. The two extrusion rollers, which are covered with food-grade silicone, extrude fresh sea buckthorn fruit, initially breaking the fruit shell and squeezing out some fruit oil and juice to form a sea buckthorn fruit mixture.

[0033] Secondary grinding: The sea buckthorn fruit mixture after primary extrusion enters between the first grinding roller 51 and the second grinding roller 52 of the secondary grinding mechanism. The second motor 5 is started, and the second motor 5 drives the first grinding roller 51 to rotate. Through the intermeshing third gear 511 and fourth gear 521, the second grinding roller 52 rotates in opposite directions at different speeds. The blunt tooth structure on the surface of the two grinding rollers rubs and grinds the mixture, further breaking down the cell walls of the sea buckthorn fruit and fully releasing the fruit oil.

[0034] Centrifugal separation: The seabuckthorn fruit mixture after secondary grinding enters the drum 61 of the centrifugal device 3 through the discharge port of the crushing device 2. The third motor 6 is started, and the third motor 6 drives the drum 61 to rotate at high speed. Centrifugal force is used to separate the seabuckthorn fruit oil from the fruit residue in the mixture. The fruit oil accumulates on the outer side of the inner wall of the drum 61, while the fruit residue remains in the center.

[0035] Fruit oil collection and slag discharge: Turn off the third motor 6, open the valve body 311 on the drain pipe 31, and discharge the accumulated sea buckthorn fruit oil through the drain pipe 31 to the collection container; after the fruit oil is completely discharged, open the slag discharge door 32 at the bottom of the centrifuge device 3 to discharge the fruit residue in the drum 61, thus completing one fresh sea buckthorn fruit oil extraction operation.

[0036] Example 2: This example uses frozen sea buckthorn fruit as the extraction raw material, combined with... Figure 1 To be continued Figure 5 Detailed explanation of the workflow: The workflow is as follows:

[0037] Raw material pretreatment: Frozen sea buckthorn berries are thawed to a semi-solid state at room temperature to avoid complete thawing and juice loss, and then fed into the crushing device 2 through the feed hopper 21.

[0038] First stage of extrusion: The first motor 4 is started, and the first extrusion roller 41 and the second extrusion roller 42 rotate synchronously in opposite directions under the transmission of the first gear 411 and the second gear 421. The two extrusion rollers, whose surfaces are coated with food-grade polyurethane, extrude the thawed semi-solid sea buckthorn fruit. Because polyurethane has stronger wear resistance, it can deal with the hard points that may exist in the frozen fruit, initially break the fruit structure and squeeze out the fruit oil.

[0039] Secondary grinding: The semi-solid sea buckthorn fruit mixture enters between the first grinding roller 51 and the second grinding roller 52. The second motor 5 is started, and the two grinding rollers rotate at different speeds under the transmission of the third gear 511 and the fourth gear 521. The blunt tooth structure fully grinds the relatively viscous semi-solid mixture, breaks up the fruit residue clumps that may solidify after freezing, and ensures that the fruit oil is fully released.

[0040] Centrifugal separation: The ground mixture is introduced into the drum 61 of the centrifuge device 3, the third motor 6 is started, and the speed of the drum 61 is controlled to be slightly higher than the speed when extracting fresh fruit. Since the semi-solid mixture is more difficult to separate, the sea buckthorn fruit oil and fruit residue are separated by centrifugal force.

[0041] Fruit oil collection and residue discharge: After centrifugation for 10-15 minutes to ensure complete separation, turn off the third motor 6 and open valve 311 to discharge sea buckthorn fruit oil; after the fruit oil is discharged, open the residue discharge door 32 to discharge the fruit residue. Since the frozen fruit residue has a low water content, it can be directly collected for other processing, such as making dried sea buckthorn fruit, thus completing the fruit oil extraction operation of frozen sea buckthorn fruit.
