Description

A low-temperature extraction device for herbal ingredients Technical Field

[0001] This utility model belongs to the field of herbal low-temperature extraction technology, specifically relating to a low-temperature extraction device for herbal components. Background Technology

[0002] Low-temperature extraction equipment for Chinese herbal plant juices is generally used in the processing of Chinese herbal plant juices to extract them at low temperatures. It mainly utilizes the principle of different freezing points (i.e., freezing points) of the extractants to extract different liquids by freezing them at low temperatures. Common extractants include ethanol, n-butanol, petroleum ether, ethyl acetate, acetone, chloroform, and methanol. Ethanol has a freezing point of -117.3℃, n-butanol -89.8℃, petroleum ether less than -73℃, ethyl acetate -83.6℃, ​​acetone -94.9℃, chloroform -63.5℃, and methanol -97.8℃. Since different extractants have different freezing points, solid-liquid separation can be achieved by adjusting the refrigeration temperature.

[0003] However, existing low-temperature extraction equipment for Chinese herbal plant juices still mixes the frozen and unfrozen solutions during freezing, making complete extraction impossible and requiring further stratification or filtration. Secondly, due to gravity, the liquid remains in the outlet pipe at the bottom of the extraction equipment. The solidification of the liquid in the outlet pipe causes blockage, making it impossible to separate different extracts after extraction, which is inconvenient for collection and use. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a low-temperature extraction device for herbal ingredients. This device aims to solve the technical problems of existing technologies where frozen and unfrozen solutions remain mixed, resulting in incomplete extraction and requiring further stratification or filtration, which also reduces extraction efficiency. Furthermore, the solidification of the liquid in the outlet pipe can cause blockage, and the inability to separate different extracts after extraction makes collection and use inconvenient.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a low-temperature extraction device for herbal ingredients, including a low-temperature extraction tank and a water outlet pipe detachably installed at the bottom of the low-temperature extraction tank. A filter screen is installed above the water outlet pipe and embedded in the low-temperature extraction tank. A sealing plug is embedded and fixed at the bottom of the water outlet pipe. A connecting seat threaded onto the water outlet pipe is fixed at the bottom of the sealing plug. A stirring rod is rotatably installed in the low-temperature extraction tank. Multiple stirring blades are installed on the stirring rod, and a scraper for cleaning ice from the surface of the filter screen is fixed at the bottom of the stirring rod.

[0008] When using this technical solution, a connecting seat is threaded onto the bottom of the outlet pipe, and a sealing plug at the top of the connecting seat is inserted into the outlet pipe to prevent liquid from condensing and clogging in the outlet pipe. A stepless speed-regulating stirring motor drives the stirring rod and stirring blades to rotate. The scraper at the bottom of the stirring rod scrapes off the frozen ice on the surface of the filter screen, and the stirring blades cause the plant juice to shake continuously during the freezing process. Therefore, during freezing, the uncold liquid is shaken and moves to the lower layer, while the frozen ice floats on the upper layer, separating the frozen solution from the uncold solution to form a solid-liquid stratification. After condensation and stratification, the connecting seat is unscrewed to separate the sealing plug from the outlet pipe, and the liquid passes through the filter screen and is discharged from the outlet pipe, realizing the separation of different liquids after extraction, thus making it more convenient to collect and use the extracted liquid.

[0009] Preferably, the top of the low-temperature extraction tank is equipped with a top cover, and a low-temperature detector is embedded in the outer wall of the low-temperature extraction tank.

[0010] Furthermore, the top of the top cover is equipped with a plurality of bolts in a circular array that are threaded into the low-temperature extraction tank, and the top of the top cover is fixed at an angle with a feed pipe, and a sealing cap is threaded onto the feed pipe.

[0011] Furthermore, the top of the top cover is fixed with a stepless speed-regulating stirring motor connected to the stirring rod, and the top of the top cover is provided with a refrigeration pipe inlet. The bottom of the low-temperature extraction tank is installed with a refrigeration pipe outlet, and multiple circulation pipes are fixed in the low-temperature extraction tank. The refrigeration pipe outlet and the circulation pipes are both connected to the refrigeration pipe inlet.

[0012] Furthermore, the bottom of the low-temperature extraction tank is fixed with a connecting part, and the top end of the water outlet pipe is threaded into the connecting part.

[0013] Furthermore, a first handle is fixed to the outer wall of the water outlet pipe, and a second handle is fixedly installed at the bottom of the connecting seat.

[0014] Furthermore, the outer wall of the filter screen is fixed with an installation ring, which is slidably inserted into the connecting part, and the top end of the water outlet pipe abuts against the installation ring.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a connecting seat threaded onto the bottom of the outlet pipe, with a sealing plug at the top of the connecting seat inserted into the outlet pipe. This prevents the liquid from condensing and clogging as it flows into the outlet pipe. A continuously variable speed stirring motor drives the stirring rod and blades to rotate. A scraper at the bottom of the stirring rod scrapes off the ice blocks frozen on the filter screen. The stirring blades cause the plant juice to slosh continuously during the freezing process. Therefore, during freezing, the uncold liquid is moved to the lower layer, while the frozen ice blocks float on the upper layer, separating the frozen solution from the uncold solution and forming a solid-liquid stratification. After condensation and stratification, the connecting seat is unscrewed to separate the sealing plug from the outlet pipe. The liquid then passes through the filter screen and is discharged from the outlet pipe, achieving the separation of different liquids after extraction, thus making the collection and use of the extracted liquid more convenient.

A stirring rod 9 is rotatably installed in the low-temperature extraction tank 1. Multiple stirring blades 12 are installed on the stirring rod 9. A scraper 14 for cleaning ice on the surface of the filter screen 13 is fixed at the bottom of the stirring rod 9.

[0026] Preferably, a top cover 2 is installed on the top of the low-temperature extraction tank 1, and a low-temperature detector 7 (preferably a DT type low-temperature thermometer) is embedded in the outer wall of the low-temperature extraction tank 1. Multiple bolts 6, threaded into the low-temperature extraction tank 1, are installed in a ring array on the top of the top cover 2. A feed pipe 3 is fixedly fixed to the top of the top cover 2 at an angle. A sealing cap is threaded onto the feed pipe 3. A stepless speed-regulating stirring motor 4 connected to the stirring rod 9 is fixed to the top of the top cover 2. A refrigeration pipe inlet 5 is provided on the top of the top cover 2. A refrigeration pipe outlet 11 is installed at the bottom of the low-temperature extraction tank 1. Multiple circulation pipes 8 are fixed in the low-temperature extraction tank 1. Both the refrigeration pipe outlet 11 and the circulation pipes 8 are connected to the refrigeration pipe inlet 5. A PTLQ series gas refrigerator is fixedly connected to the refrigeration pipe inlet 5 and the refrigeration pipe outlet 11. The outlet temperature of the equipment is between -20°C and -120°C.

[0027] As shown in Figures 3 and 4, a connecting part 16 is fixed to the bottom of the low-temperature extraction tank 1. The top end of the water outlet pipe 20 is threaded into the connecting part 16. A first handle 17 is fixed to the outer wall of the water outlet pipe 20. A second handle 18 is fixed to the bottom of the connecting seat 19. An installation ring 15 is fixed to the outer wall of the filter screen 13. The installation ring 15 is slidably inserted into the connecting part 16. The top end of the water outlet pipe 20 abuts against the installation ring 15. The stepless speed-regulating stirring motor 4 drives the stirring rod 9 and the stirring blade 12 to rotate. The scraper 14 at the bottom of the stirring rod 9... Ice blocks frozen on the surface of filter screen 13 are scraped off, and stirring blade 12 causes the plant juice to shake continuously during the freezing process. Therefore, during freezing, the unfrozen liquid is shaken and moves to the lower layer, while the frozen ice blocks float on the upper layer, separating the frozen solution from the unfrozen solution and forming a solid-liquid stratification. After condensation and stratification, the connecting seat 19 is unscrewed to separate the sealing plug 10 from the water outlet pipe 20. The liquid passes through filter screen 13 and is discharged from water outlet pipe 20, realizing the separation of different liquids after extraction, thus making it more convenient to collect and use the extracted liquid.

[0028] Working principle: When using the device of this technical solution, the extract is input into the low-temperature extraction tank 1 through the inlet pipe. The refrigeration pipe inlet 5, the refrigeration pipe outlet 11, and the circulation pipe 8 cool the inside of the low-temperature extraction tank 1. The sealing plug 10 at the top of the connector 19 is inserted into the outlet pipe 20 to prevent the liquid from flowing into the outlet pipe 20 and causing condensation and blockage. The stepless speed-regulating stirring motor 4 is started to drive the stirring rod 9 and the stirring blade 12 to rotate. The scraper 14 at the bottom of the stirring rod 9 scrapes off the ice blocks frozen on the surface of the filter screen 13. The stirring blade 12 makes the plant juice shake continuously during the freezing process. Therefore, during freezing, the unfrozen liquid is shaken and moves to the lower layer, while the frozen ice blocks float on the upper layer, so that the frozen solution is separated from the unfrozen solution, forming a solid-liquid stratification. After condensation and stratification, the connector 19 is unscrewed to separate the sealing plug 10 from the outlet pipe 20. The liquid passes through the filter screen 13 and is discharged from the outlet pipe 20, realizing the separation of different liquids after extraction, thus making it more convenient to collect and use the extracted liquid.
