Description

Technical Field

[0001] The invention relates to the technical field of spice oil purification, in particular to natural spice freezing separation and subdivision equipment and a process. Background Art

[0002] In the production and processing of vegetarian and brain-based natural spices, the traditional freezing crystallization process has defects.

[0003] The traditional method is to inject about 80% to 85% of natural flavoring materials such as vegetables and brains into a high-level tank, and then transport them to multiple open barrels or pallets in the freezer through pipelines. After closing the door, the refrigeration unit is started to freeze for about 16 hours. When the temperature drops to -26℃ to -28℃, the refrigeration unit is turned off, and the freezer door is opened manually. A gear pump is used to extract the uncrystallized low-content oil (content is 40%-50%) in the barrel or pallet. This low-content oil is all transported to the distillation workshop for re-fractionation to increase the content.

[0004] The crystals are then crushed manually or by a crusher, and then placed in a centrifuge for drying (centrifugation time is about 30 to 40 minutes). Finally, the high-purity crystals are poured into a melting barrel with a jacket and melted with steam to obtain natural spice oils of about 99% purity.

[0005] The 60%-80% vegetarian and ceramide natural flavor oils thrown out by the centrifuge, of which 60%-70% vegetarian and ceramide oils need to be transported to the distillation workshop to be re-divided to increase the content, while 70%-80% can be refrozen again.

[0006] This process not only relies on a large amount of manpower, resulting in high labor costs, but also has a cumbersome and complicated process; the large number of re-divisions increases production costs; at the same time, the yield of about 99% high-content vegetarian and brain-based natural flavors is as low as about 25%, and the purity of the final product is difficult to reach the ideal content of more than 99.6%, and it is even more difficult to meet market demand, affecting production efficiency and economic benefits, and unable to meet the growing market demand.

[0007] Therefore, how to simplify the operating process, reduce the workload of re-division, and improve the production efficiency of vegetarian and brain-based natural spices is a problem that needs to be solved at present. Summary of the Invention

[0061] When sampling, the driving motor 721 starts to work, and the moving driving motor 721 can drive the cam 722 to rotate. At this time, the moving cam 722 can drive the driving wheel 723 to move, and the moving driving wheel 723 can drive the moving seat 725 to move in the axial direction of the valve seat 71, and then the moving moving seat 725 can drive the connecting valve stem 73 to move. At this time, the connecting valve stem 73 can start to move on the limit seat 741. As the cam 722 rotates, the distal area on the cam 722 moves away from the driving wheel 723. At this time, the first spring 727 that is squeezed and deformed can push the mounting seat 726 to move, so that the mounting seat 726 moves toward the direction of the driving motor 721, and then the connecting valve stem 73 moves in the opposite direction. Through the movement of the connecting valve stem 73, the sampling and transportation of the crude oil can be completed, and this part of the crude oil can be discharged at a certain speed to meet the sampling conditions of the quality inspection chromatograph.

[0062] The regulating portion 76 includes an adapter seat 765 sleeved on the connecting valve stem 73, a sleeve 761 sleeved on the adapter seat 765, a ring gear 762 provided on the sleeve 761, a gear rod 764 meshing with the ring gear 762, a driving rod 763 provided on the gear rod 764, the sleeve 761 extends toward one end of the driving portion 72 to form an extension tube, and a limiting ring 766 sleeved on the extension tube; one end of the first spring 727 is located on the limiting ring 766; when the sampling volume needs to be adjusted, the driving rod 763 is pushed, and the moving driving rod 763 can drive the gear rod 764 to move, and the moving gear rod 764 can drive the ring gear 762 The ring gear 762 rotates, and then the moving adapter 765 can drive the adapter seat 765 to move, and then the moving adapter seat 765 can drive the connecting valve stem 73 to rotate, thereby adjusting the position of the inclined groove 732 on the connecting valve stem 73, thereby adjusting the radial distance between the inclined groove 732 and the third groove 744, changing the stroke distance of the crude oil, thereby changing the sample amount in the area between the limit seat 741 and the top of the connecting valve stem 73, avoiding excessive sampling and causing waste of crude oil; the above structure can accurately adjust the position of the inclined groove 732 on the connecting valve stem 73, change the distance between the inclined groove 732 and the third groove 744, accurately control the stroke distance of the crude oil, and then accurately adjust the sampling amount to meet different detection needs.

[0063] The limiting portion 74 includes a limiting seat 741 sleeved on the connecting valve stem 73, a first groove 742 formed on the limiting seat 741, a second groove 743 connected to the first groove 742, and a third groove 744 connected to the second groove 743.

The connecting valve stem 73 is provided with an inclined groove 732 and a fourth groove 733 connected to the inclined groove 732. The third groove 744 is an annular structure. The first groove 742 is connected to the oil filling port. The sampling volume is changed by adjusting the position of the connecting valve stem 73 in the limiting seat 741. The sampling operation is divided into three stages.

[0064] The first stage is: the cam 722 is driven by the driving motor 721 to move, so that the connecting valve stem 73 can move toward the cam 722. As the connecting valve stem 73 moves, the connecting valve stem 73 can move away from the third groove 744. At this time, the crude oil can flow along the first groove 742, the second groove 743 and the third groove 744 into the area between the limit seat 741 and the top of the connecting valve stem 73. By changing the shape of the cam 722, the position of the distal area of the cam 722 is changed, and then the overlapping area between the third groove 744 and the connecting valve stem 73 is changed, and the capacity of the crude oil in the area between the limit seat 741 and the top of the connecting valve stem 73 is changed, completing the first stage of sampling.

[0065] The second stage is: after the sampling work is completed, the cam 722 can move the connecting valve stem 73 away from the cam 722. At this time, the connecting valve stem 73 can block the oil outlet end 753 of the third groove 744, and pressurize the sample oil as the connecting valve stem 73 moves. When the connecting valve stem 73 moves to a predetermined position, the sample oil can overcome the elastic force of the supporting spring 754, so that the sample oil can be discharged from the oil outlet portion 75 and transported to the quality inspection chromatograph to complete the detection work;

[0066] The third stage is: after completing the work of the second stage, the connecting valve stem 73 still moves in the direction away from the cam 722, so that the third groove 744 is connected with the inclined groove 732, and then the remaining principle oil in the area between the limit seat 741 and the top of the connecting valve stem 73 can move along the fourth groove 733 and the inclined groove 732 to the third groove 744. In this process, even if the connecting valve stem 73 still moves in the direction away from the cam 722, the raw oil will not be discharged from the oil outlet 75, ensuring the stability of the raw oil discharge amount, and the raw oil that has not entered the quality inspection chromatograph can be located at the oil filling port along the third groove 744, the second groove 743 and the first groove 742. By providing a one-way valve and a drainage tube at the oil filling port, a connecting port is provided circumferentially of the oil filling port, and the unit valve is provided at the connecting port, so that this part of the raw oil can be discharged, which can avoid the waste of raw oil and prevent this part of the raw oil from affecting subsequent test results.

[0067] The oil outlet portion 75 includes an oil outlet seat screwed to the valve seat 71, an oil outlet cavity 751 provided in the oil outlet seat, an oil outlet end 753 provided on the oil outlet seat, a guide tube 752 connected to the oil outlet end 753 and located in the oil outlet cavity 751, a valve core 755 located in the oil outlet cavity 751, and a support spring 754 for connecting the valve core 755 and the oil outlet seat; the valve core 755 is cross-shaped and has a plurality of grooves on its circumference; one end of the guide tube 752 is provided with an oil outlet. The delivery groove and the connecting hole for connecting the delivery groove and the oil outlet chamber 751; as the connecting valve stem 73 moves, the raw oil can apply pressure to the valve core 755. When the applied pressure is greater than the elastic force generated by the supporting spring 754, the valve core 755 can move toward the oil outlet end 753, so that the sample oil can move into the oil outlet chamber 751, and then be discharged from the oil outlet end 753 along the connecting hole on the guide tube 752. The discharged sample oil is transported to the quality inspection chromatograph at a certain initial velocity to complete the detection work.

[0068] A natural flavor freezing separation and subdivision process comprises the following steps:

[0069] S1: First, the raw oil is transported to the freezing tank 1 through the gear pump. When the raw oil in the freezing tank 1 reaches a certain volume, the refrigeration unit 2 starts to work, making the temperature in the freezing tank 1 reach a preset value, thereby causing the raw oil to crystallize;

[0070] S2: Then, the discharge valve 5 is opened to discharge the uncrystallized low-content oil, and the discharged low-content oil is transported to the fractionation workshop for re-fractionation;

[0071] S3: Then the air heater 3 starts working, thereby increasing the temperature in the freezing tank 1, so that the crystallized raw oil becomes liquid, and then discharge is carried out. At this time, the discharged oil is medium-purity oil. During the discharge process, the oil content is monitored in real time using a quality inspection chromatograph;

[0072] S4: Repeat steps S2-S3 to refrozen and thaw the crude oil in the tank. After thawing, the temperature in the tank is sufficient to melt the high-purity crystals, and the melted product is transported through the provided discharge valve 5.

[0073] In a further embodiment, at first, use gear pump that the element class, the brain class natural spices of 80%~85% content are injected into freezing tank 1, open refrigeration unit 2 and freeze, continue freezing about 16~20 hours, make the element class natural spices temperature in the jar drop to about-32 ℃, stop freezing during about-35 ℃ of brain class.At this moment, open the discharging valve 5 on the tank body, discharge the uncrystallized low-content element class, the brain class natural spices oil that account for 25% of total amount, wherein sassafras oil content is 40%-50%, eucalyptus oil content is 60-70%, anethole oil etc. brain class oils are at 50-60%, and this part oil is transported to the further multiple division raising content of fractionation workshop again.Then open and melt switch, start air heater 3 pairs of jar interior crystallization body heating, element class, the brain class natural spices oil after the heating thaw can continue to discharge from the discharging port at the bottom of the jar, this part oil content can raise gradually, and quantity is about 40% of total amount, and 70% above content can carry out secondary freezing process again. During the discharge process, the oil content is monitored in real time using a quality inspection chromatograph. When the content reaches about 99%, the discharge valve 5 is closed. Subsequently, the steam fin radiator (air heater 3) at the top of the tank is opened to continue heating the material in the tank. When the temperature in the tank reaches about 40°C, the heating is stopped. The remaining crystals in the tank are allowed to slowly melt and settle for a certain period of time with the help of the residual heat in the tank. After that, the discharge valve 5 at the bottom of the tank is opened again. At this time, the purity of the discharged vegetarian natural flavors can reach more than 99.6%, and the purity of the brain natural flavors can reach more than 99.4%, accounting for about 35% of the total. Through this process, efficient purification of vegetarian and brain natural flavors is achieved.

[0074] Description of the working principle: First, the raw oil is transported to the freezing tank 1 through the gear pump. When the raw oil in the freezing tank 1 reaches a certain capacity, the refrigeration unit 2 starts to work, so that the temperature in the freezing tank 1 reaches the preset value, so that the raw oil is crystallized; then the discharge valve 5 is opened to discharge the uncrystallized low-content oil, and the discharged low-content oil is transported to the distillation workshop for re-fractionation; then the air heater 3 starts to work, so as to increase the temperature in the freezing tank 1, so that the crystallized raw oil becomes liquid, and then the discharge work is carried out. At this time, the discharged oil is medium-purity oil. During the discharge process, the oil content is monitored in real time using a quality inspection chromatograph; repeat the above steps to realize the refrozen and thawed work of the raw oil in the tank. After thawing, the temperature in the tank body can melt the high-purity crystals, and the delivery of the melted product is completed through the set discharge valve 5;

[0075] When sampling is performed, the driving motor 721 starts to work, and the moving driving motor 721 can drive the cam 722 to rotate. At this time, the moving cam 722 can drive the driving wheel 723 to move, and the moving driving wheel 723 can drive the moving seat 725 to move in the axial direction of the valve seat 71, and then the moving moving seat 725 can drive the connecting valve stem 73 to move. At this time, the connecting valve stem 73 can start to move on the limit seat 741. As the cam 722 rotates, the distal area on the cam 722 moves away from the driving wheel 723. At this time, the first spring 727 that is squeezed and deformed can push the mounting seat 726 to move, so that the mounting seat 726 moves toward the driving motor 721, and then the connecting valve stem 73 moves in the opposite direction. Through the movement of the connecting valve stem 73, the sampling and delivery of the crude oil can be completed; when the sampling volume needs to be adjusted, the driving rod 763 is pushed at this time, and the moving driving rod 763 can drive the gear rod 764 to move. At this time, the moving gear rod 764 can drive the ring gear 762 to rotate, and then the moving ring gear 762 can drive the adapter seat 765 to move, and then the moving adapter seat 765 can drive the connecting valve stem 73 to rotate, thereby adjusting the position of the inclined groove 732 on the connecting valve stem 73, thereby adjusting the radial distance between the inclined groove 732 and the third groove 744, changing the stroke distance of the crude oil, and thus changing the sample amount in the area between the limit seat 741 and the top of the connecting valve stem 73, avoiding excessive sampling and causing waste of crude oil; as the connecting valve stem 73 moves, the crude oil can apply pressure to the valve core 755. When the applied pressure is greater than the elastic force generated by the support spring 754, the valve core 755 can move toward the oil outlet end 753, allowing the sample oil to move into the oil outlet chamber 751, and then be discharged from the oil outlet end 753 along the connecting hole on the guide tube 752. The discharged sample oil is transported to the quality inspection chromatograph at a certain initial velocity to complete the detection work.
