Description

Technical Field

[0001] The present invention relates to the technical field of spice extraction, and more specifically, it relates to a distillation and condensation device for spice extraction. Background Art

[0002] During the spice extraction process, the distillation and condensation device is one of the core devices. It uses the principle of steam distillation or hydrodistillation to separate the volatile aromatic components in spice plants (such as flowers, leaves, roots, barks, fruits) from the raw materials, and condenses them to change from a gaseous state to a liquid state that is easy to collect.

[0003] In the prior art, the traditional distillation and condensation device usually consists of core components such as a distillation tank, a condenser, and a steam generator. To facilitate the cleaning and maintenance of the interior of the distillation tank, the existing design generally adopts a separable upper and lower tank structure. However, during the cleaning operation, it is necessary to rely on external lifting equipment to first lift the upper tank and completely separate it from the lower tank; after the cleaning is completed, it is necessary to use the lifting equipment again to reset the upper tank and precisely align and assemble it with the lower tank. This disassembly and assembly process has complex operating steps, which not only significantly increases the workload and difficulty of the cleaning operation, but also greatly prolongs the overall maintenance time. Summary of the Invention

[0004] The purpose of the present invention is to provide a distillation and condensation device for spice extraction to solve the above-mentioned technical problems.

[0005] The present invention solves the above-mentioned existing technical problems through the following technical solutions: The present invention provides a distillation and condensation device for spice extraction, including: a distillation tank, a support mechanism, a condenser, a steam generator, and a collection tank. The distillation tank includes a stirring assembly and an upper tank and a lower tank spliced together, and the upper tank and the lower tank are locked by a locking member. The lower tank is connected to the steam generator through a telescopic steam delivery pipe; The support mechanism includes a base and a connecting body fixed to the lower tank. The base is connected to the upper tank through a limiting rod, and the connecting body is slidably connected to the limiting rod. An elevating drive assembly is provided on the base, and the lower tank is driven to linearly lift through the elevating drive assembly to achieve the closing and separation from the upper tank.

[0006] Preferably, the elevating drive assembly includes a lead screw rotatable on the base and a driving part. The lead screw is threadedly connected to the connecting body, and the driving part is used to drive the lead screw to rotate.

[0007] Preferably, the driving part includes a driving motor and two meshing bevel gears. The driving end of the driving motor is fixed to one of the bevel gears; the other bevel gear is fixed to the bottom end of the lead screw.

[0008] Preferably, two limiting rods are provided, and the two limiting rods and the lead screw are evenly distributed around the outside of the distillation tank.

The top end of the stirring blade is connected to the driving end of the stirring motor, and a bottom plate with mesh holes is provided at the bottom of the lower tank body.

[0010] Preferably, the stirring body is composed of a shaft body and a plurality of blades evenly distributed outside the shaft body. The blade located at the lowermost part is in contact with the top surface of the bottom plate.

[0011] Preferably, the blade includes two first blades arranged obliquely. The two first blades are arranged in a 180-degree alignment around the outside of the shaft body, and an inclined second blade is connected between the end of the first blade far from the shaft body and the outside of the shaft body.

[0018] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0019] Please refer to Figures 1 to 2 , a distillation and condensation device for spice extraction, comprising: a distillation tank 1, a support mechanism 2, a condenser 3, a steam generator 4, and a collection tank 5; the distillation tank 1 includes a stirring assembly 11 and an upper tank body 12 and a lower tank body 13 spliced together, and the upper tank body 12 and the lower tank body 13 are locked by a locking member, and the locking member can be a plurality of bolts distributed circumferentially; the lower tank body 13 is communicated with the steam generator 4 through a telescopic steam delivery pipe 14, the condenser 3 is communicated with the top of the upper tank body 12 through a pipeline, the steam generator 4 is communicated with the return end of the condenser 3 through a pipeline, and the output end of the condenser 3 is communicated with the collection tank 5 through a pipeline.

[0020] The support mechanism 2 includes a base 21 and a connecting body 22 fixed on the lower tank body 13. The base 21 is connected to the upper tank body 12 through a limit rod 23, the connecting body 22 is slidably connected to the limit rod 23, and a lifting drive assembly 24 is provided on the base 21. The lower tank body 13 is driven to linearly lift through the lifting drive assembly 24 to realize the closing and separation from the upper tank body 12.

[0021] When the above-mentioned distillation and condensation device is in use, spices are added through the inlet at the top of the upper tank body 12, and then high-temperature steam is introduced into the distillation tank 1 through the steam generator 4. After the high-temperature steam contacts the spices, evaporation occurs, and the effective substances in the spices are carried into the condenser 3 from the top of the upper tank body 12. At the same time, the spices are slowly stirred by the stirring mechanism so that the spices can be evenly contacted with the steam. After the steam enters the condenser 3, it is quickly cooled and liquefied, and then transported to the collection tank 5. When the distillation and condensation device needs to be cleaned after being used for a period of time, after the spices are taken out from the discharge port at the bottom of the lower tank body 13, the locking fastener is removed, and the lower tank body 13 can be driven to descend by the lifting drive assembly 24, so that it is gradually separated from the upper tank body 12. When the lower tank body 13 descends to the preset height, the lifting drive assembly 24 stops driving. At this time, the lower tank body 13 is completely separated from the upper tank body 12 and remains stationary respectively. Then, the inner parts of the lower tank body 13 and the upper tank body 12 can be cleaned respectively. After the cleaning is completed, the lower tank body 13 can be driven by the lifting drive assembly 24 to move upward and fit with the upper tank body 12, and then the docking part of the two can be fixed with the locking fastener. At this time, the cleaning operation is completed. Compared with the traditional method of using a hoisting mechanism to assist in hoisting and separating, the distillation and cooling device set in the present invention has a separation function itself, can automatically realize the separation of the upper and lower tank bodies 13, and adopts the method of linear separation of the lower tank body 13 moving downward. The separation action only moves within the limited height range of the current device, which is not only not easily restricted by the external space, but also has a faster separation and assembly speed, greatly reducing the disassembly and assembly difficulty and making the cleaning operation more convenient.

[0022] Please refer to Figures 2 to 3 , in order to realize the automatic downward movement of the lower tank body 13, the present invention designs the following scheme: The lifting drive assembly 24 includes a lead screw 241 rotatably mounted on the base 21 and a driving part. The lead screw 241 is threadedly connected to the connecting body 22, and the driving part is used to drive the lead screw 241 to rotate. The driving part includes a driving motor 242 and two meshing bevel gears 243. The driving end of the driving motor 242 is fixed to one of the bevel gears 243; the other bevel gear 243 is fixed to the bottom end of the lead screw 241.

[0023] When the above-mentioned lifting drive assembly 24 drives the lower tank body 13 to lift, by rotating the driving motor 242, the two bevel gears 243 can be driven to rotate synchronously, and the lead screw 241 is synchronously driven by the bevel gears 243. Since the connecting body 22 is slidably limited by the limiting rod 23, under the driving action of the lead screw 241, it can drive the lower tank body 13 to move linearly together. After the lower tank body 13 descends to the required position, the driving motor 242 stops rotating. Under the thread locking action of the lead screw 241, the connecting body 22 can be self-locked, so that the connecting body 22 and the lower tank body 13 remain stationary.

[0024] Please refer to Figures 2 to 3 , in order to further improve the stability of the lower tank body 13 during movement, the present invention optimizes the above solution: the number of the limiting rods 23 is set to two, and the two limiting rods 23 and the lead screw 241 are evenly distributed around the outside of the distillation tank 1. The two limiting rods 23 can increase the stability of the lower tank body 13 during movement.

[0025] Please refer to Figures 4 to 5 , the stirring assembly 11 includes a stirring motor 111 fixed on the upper tank body 12 and a stirring body arranged in the distillation tank 1. The top end of the stirring blade is connected to the driving end of the stirring motor 111, and the bottom of the lower tank body 13 is provided with a bottom plate 15 with mesh holes. The stirring body is composed of a shaft body 112 and a plurality of blades 113 evenly distributed on the outside of the shaft body 112. The lowermost blade 113 is attached to the top surface of the bottom plate 15. The number of the blades 113 can generally be set to three, two of which are located in the lower tank body 13 and the remaining one is located in the upper tank body 12. By contacting the bottom plate 15 with the lowermost blade 113, during the stirring in the distillation process, the spices adsorbed on the top surface of the bottom plate 15 can be scraped, preventing the spices from adsorbing on the top surface of the bottom plate 15 and thus causing blockage, which affects the upward flow of steam.

[0026] Specifically, in order to better stir the spices and promote their full contact with the steam, the present invention designs the following solution: the blade 113 includes two first blades 1131 arranged obliquely, and the two first blades 1131 are arranged in a 180-degree alignment around the outside of the shaft body 112. The inclination angle of the first blade 1131 itself is 10 - 15 degrees. When the obliquely inclined first blade 1131 contacts the bottom plate 15, it can generate a shoveling action on the spices adsorbed on the top surface of the bottom plate 15, enabling the spices to be easily separated from the bottom plate 15. Its angle range of 10 - 15 degrees ensures both a relatively small resistance and relatively little damage to the spices. A second blade 1132 in an inclined shape is connected between the end of the first blade 1131 far from the shaft body 112 and the outside of the shaft body 112. The inclination angle of the second blade 1132 itself is 45 - 50 degrees, and the included angle between the first blade 1131 and the second blade 1132 is 30 - 35 degrees. The design of the second blade 1132 is to increase the contact area between the stirring body and the spices, enhance the movement range of the spices, and enable the steam to fully contact the spices.

[0027] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present invention, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present invention.
