Description

Technical Field

[0001] This utility model belongs to the field of peppermint oil separation technology, specifically relating to a high-efficiency peppermint oil separation and purification device. Background Technology

[0002] In the separation and purification of peppermint oil, distillation equipment is used to separate the peppermint stems and leaves. Existing peppermint oil distillation equipment uses multiple layers of steam trays to support the peppermint stems and leaves, which are then laid flat on the trays. The peppermint stems and leaves are distilled by the upward-moving steam from the lower layers, and the peppermint oil in the stems and leaves is discharged along with the steam. The looseness of the peppermint stems and leaves directly determines the flow path of the steam, thus affecting the distillation effect. However, in the later stages of distillation, the peppermint leaves become too wet, softened, and even clump together due to prolonged steam exposure, which seriously affects the flow path of the steam. This results in low distillation efficiency and poor distillation effect, especially since the residual peppermint oil in the center of the clumping area can be up to three times that of the edge area. The steam flow path of existing peppermint oil distillation equipment needs to be optimized. Utility Model Content

[0003] This invention provides a highly efficient peppermint oil separation and purification device that can expand and increase the steam flow path of peppermint stems and leaves, and distill the peppermint stems and leaves more evenly.

[0004] This utility model provides the following technical solution: a high-efficiency peppermint oil separation and purification device, including a peppermint oil distillation tank, a distillation tube, a cabinet door, and several mesh containers. The inner wall of the bottom end of each mesh container is provided with several sets of vertically distributed connecting rings. The lowermost connecting ring in each set is fixedly connected to the inner wall of the bottom end of the mesh container. A spring is fixedly connected between two adjacent connecting rings in the same set. An outwardly expanding support rod is fixedly connected to the side wall of each connecting ring. A sealing telescopic sleeve rod is fixedly connected between the uppermost connecting ring and the lowermost connecting ring in the same set. Several sealing telescopic sleeve rods are connected through a gas conveying pipeline network.

[0005] One end of the gas delivery pipeline is fixedly connected to a threaded connector.

[0006] The gas delivery pipeline is fitted with a limiting sleeve on its outer wall, and the limiting sleeve is fixedly connected to the inner wall of the grid container.

[0007] Among them, several of the threaded connectors are detachably connected to an external air supply pipe on one side, and the external air supply pipe extends outward through the side wall of the peppermint oil distillation tank.

[0008] An electric control valve is installed on the external air supply pipe.

[0009] An air pump is fixedly connected to one side of the electric control valve, and an air supply pump is fixedly connected to the other side of the electric control valve.

[0010] The depth of the mesh container is greater than the maximum extension length of the sealing telescopic sleeve.

[0011] The beneficial effects of this utility model are: by using multi-layered connecting rings and outwardly expanding support rods to provide three-dimensional support for the mint stems and leaves, the looseness of the mint stems and leaves can be improved during the placement stage. The hollow structure of the connecting rings and springs can be placed inside the mint stems and leaves to form a permanent steam flow path. Furthermore, in conjunction with the sealing telescopic sleeve rod and gas delivery pipeline, the mint stems and leaves can be lifted in layers during the distillation process by using the connecting rings and outwardly expanding support rods, which can increase and expand the steam flow path of the mint stems and leaves, and distill the mint stems and leaves more evenly.

[0012] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1-4The present invention provides the following technical solution: a high-efficiency peppermint oil separation and purification device, comprising a peppermint oil distillation tank 1, a distillation tube 11, a cabinet door 12 and several grid-like containers 2. The inner wall of the bottom end of the grid-like containers 2 is provided with several sets of vertically distributed connecting rings 3. The bottommost connecting ring 3 of each set is fixedly connected to the inner wall of the bottom end of the grid-like containers 2. A spring 31 is fixedly connected between two adjacent connecting rings 3 in the same set. An outwardly expanding support rod 32 is fixedly connected to the side wall of the connecting ring 3. A sealing telescopic sleeve rod 33 is fixedly connected between the topmost connecting ring 3 and the bottommost connecting ring 3 in the same set. Several sealing telescopic sleeve rods 33 are connected through a gas conveying pipeline network 4.

[0019] In this implementation plan: before distillation, when arranging the mint stems and leaves, the controller controls the suction pump 52 to draw gas from the sealed telescopic sleeve 33 through the gas delivery network 4 and the external gas supply pipe 5. This causes the multi-layered connecting rings 3 to converge downwards, and the spring 31 to be in an elastic contracted state. Subsequently, the staff evenly arranges the mint stems and leaves in multiple grid-like containers 2. The grid-like containers 2 intercept the overflow of mint stems and leaves on all four sides. The multi-layered connecting rings 3 and the outwardly expanding support rods 32 provide three-dimensional support for the mint stems and leaves. The outwardly expanding support rods 32 extend into the gaps between the mint stems and leaves, which can improve the balance during the arranging stage. The loosening of the peppermint stems and leaves increases the space between them. After closing the cabinet door 12, the distillation stage begins. Water vapor generated at the bottom of the peppermint oil distillation tank 1 passes through the peppermint stems and leaves in the mesh container 2 and enters the distillation tube 11, then is transported to the external condensation mechanism. The hollow structure of the connecting ring 3 and spring 31 can be placed inside the peppermint stems and leaves to form a permanent steam flow path. During the process, the peppermint stems and leaves are eroded and softened by the water vapor. As the temperature inside the peppermint oil distillation tank 1 rises, the gas volume inside the sealing telescopic sleeve 33 increases, causing the length of the sealing telescopic sleeve 33 to increase slightly. The connecting ring 3 expands under the elastic force of the spring 31, initially lifting the mint stems and leaves with the help of the connecting ring 3 and the outward expansion support rod 32. At a suitable time, the electric control valve 51, in conjunction with the air pump 53, supplies gas to the external air supply pipe 5, which then delivers gas to multiple sealing telescopic sleeves 33 via the gas supply network 4. The air pressure inside the sealing telescopic sleeves 33 increases, and the connecting ring 3 expands under the elastic force of the spring 31, further lifting the stacked mint stems and leaves in layers. The outward expansion support rod 32 extends into the gaps between the mint stems and leaves, lifting them upwards, thus expanding and increasing the thickness of the leaves. The steam flow path of the lotus stems and leaves allows for more uniform distillation of the mint stems and leaves. The sealing telescopic rods 33 in the multiple grid-filled drawers 2 are connected to the gas delivery network 4 and the external gas supply pipe 5, maintaining a consistent internal air pressure in all sealing telescopic rods 33. Under the elastic force of the spring 31, the expansion length is consistent, thereby uniformly lifting the mint stems and leaves in all parts. The electric control valve 51, the suction pump 52, and the delivery pump 53 are all controlled by the controller to more accurately control the volume of air entering and leaving the drawer. The outer sleeve of the sealing telescopic rod 33 is sealed to the inner telescopic rod by a sealing ring.

[0020] One end of the gas delivery pipeline 4 is fixedly connected to a threaded connector 41; by setting the threaded connector 41, it is easy to connect the gas delivery pipeline 4 to the external gas delivery pipe 5.

[0021] A limiting sleeve 42 is fitted on the outer wall of the gas transmission pipeline 4, and the limiting sleeve 42 is fixedly connected to the inner wall of the grid container 2; the gas transmission pipeline 4 can be limited by setting the limiting sleeve 42.

[0022] Several threaded connectors 41 are detachably connected to an external air supply pipe 5 on one side. The external air supply pipe 5 extends outward through the side wall of the peppermint oil distillation tank 1. Multiple branch pipes extend from one side of the external air supply pipe 5. The branch pipes are threadedly connected to the threaded connectors 41 through threaded joints. The connection is sealed by a sealing gasket. The location where the branch pipes of the external air supply pipe 5 pass through the side wall of the peppermint oil distillation tank 1 is sealed by a sealing ring. The sealing ring used can withstand a high temperature of 100 degrees Celsius.

[0023] An electric control valve 51 is installed on the external gas supply pipe 5; by setting the electric control valve 51, the connection of the external gas supply pipe 5 can be controlled, and the external gas supply pipe 5 can be kept closed when gas is not needed.

[0024] An air pump 52 is fixedly connected to one side of the electric control valve 51, and an air supply pump 53 is fixedly connected to the other side of the electric control valve 51. By setting the air pump 52, the gas in the sealing telescopic sleeve 33 can be drawn through the gas delivery pipeline 4 and the external air supply pipe 5. The sealing telescopic sleeve 33 is contracted by the air pressure to compress the spring 31. The air supply pump 53 can deliver gas to the sealing telescopic sleeve 33.

[0025] The depth of the mesh container 2 is greater than the maximum extension length of the sealing telescopic sleeve 33; the greater depth of the mesh container 2 is to prevent the mint stems and leaves from overflowing from the mesh container 2 when the connecting ring 3 and the outward expansion support rod 32 lift the mint stems and leaves.

[0026] The working principle and usage process of this utility model: The controller controls the air pump 52 to draw gas from the sealed telescopic sleeve 33 through the gas delivery pipeline 4 and the external gas supply pipe 5, causing the multi-layered connecting rings 3 to converge downwards, and the spring 31 to be in an elastic contraction state. Then, the staff evenly places the mint stems and leaves in multiple grid holding drawers 2. The multi-layered connecting rings 3 and the outwardly expanding support rods 32 provide three-dimensional support for the mint stems and leaves, which can improve the looseness of the mint stems and leaves during the placement stage and increase the gap path between the mint stems and leaves. After closing the cabinet door 12, the distillation stage begins. The hollow structure of spring 31 can be placed inside the mint stems and leaves to form a permanent steam flow path. During the process, the mint stems and leaves are eroded and softened by water vapor. At the appropriate time, the electric control valve 51 and the air pump 53 cooperate to deliver gas to the external air pipe 5, and deliver it to multiple sealed telescopic sleeves 33 through the gas delivery network 4. The air pressure inside the sealed telescopic sleeves 33 increases, and the connecting ring 3 expands under the elastic force of spring 31, which can further lift the stacked mint stems and leaves in layers, expand and increase the steam flow path of the mint stems and leaves, and distill the mint stems and leaves more evenly.
