[0003] The announcement number is CN208943504U, which discloses "a low-temperature extraction device for lily extract, including an extraction box, a support and buffer base, universal wheels with brakes, a collection tank, a vacuum pump, and a condenser. A variable frequency motor is fixedly installed on the top of the extraction box via a bracket. The output end of the variable frequency motor is fixedly connected to a threaded rod via a coupling. A fixing plate is fixedly installed on the lower end face of the threaded rod. The threaded rod is threadedly connected to an upper filter screen and a lower filter screen.

Utility Model Content
[0005] The purpose of this invention is to provide a low-temperature extraction device for plant extracts to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A low-temperature extraction apparatus for plant extracts, comprising:
[0008] An extraction assembly is installed inside the extraction chamber. The extraction assembly includes a filter cartridge that is fixedly installed inside the extraction chamber by a bracket. A water pipe is movably installed inside the filter cartridge, and a spiral blade is fixedly installed on the outer surface of the water pipe.
[0009] A circulation assembly is fixedly installed on one side of the extraction chamber. The circulation assembly includes a circulation pump, one end of which is fixedly connected to a connecting pipe.
[0010] The feeding assembly is fixedly installed on the lower surface of the filter cartridge.
[0011] Furthermore, a No. 3-way pipe is fixedly embedded in the lower surface of the extraction chamber, and a No. 1 solenoid valve is fixedly installed at one end of the No. 1 3-way pipe.
[0012] Furthermore, the outer surface of the water pipe is provided with multiple water distribution holes at equal intervals, the upper end of the extraction chamber is fixedly installed with a motor by a bracket, the output end of the motor and the outer surface of the water pipe are fixedly installed with two meshing gears, and the upper end of the filter cartridge is fixedly embedded with a feed pipe that passes through the extraction chamber.
[0013] Furthermore, the other end of the circulating pump is fixedly connected to the other end of the No. 1 three-way pipe, a No. 2 solenoid valve is fixedly installed at one end of the No. 1 three-way pipe, a No. 2 three-way pipe is fixedly installed at one end of the No. 2 solenoid valve, and a No. 3 solenoid valve is fixedly installed at one end of the No. 2 three-way pipe.
[0014] Furthermore, the water pipe passes through the extraction chamber and is rotatably connected to the extraction chamber. A rotary joint is fixedly installed at the upper end of the water pipe, and one end of the rotary joint is fixedly connected to the No. 2 three-way pipe.
[0015] Furthermore, the feeding assembly includes:
[0016] The feed pipe is fixedly embedded in the lower end surface of the filter cartridge;
[0017] The storage frame is fixedly embedded and installed on the outer surface of the feed tube;
[0018] The baffle is slidably connected inside the storage box.

[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. The motor drives the water pipe to rotate the spiral blades, squeezing the raw material downwards and extruding the extract. Then, the motor is reversed, causing the spiral blades to rotate in the opposite direction, lifting and breaking up the raw material. The solvent is then sprayed out from the water separator at a certain pressure, flushing the raw material and quickly breaking it up. The solvent then carries the precipitated extract out of the filter cartridge and into the extraction chamber. By placing the plant material into the filter cartridge, the solvent impacts the plant material at a certain pressure, accelerating the extraction speed. The forward and reverse rotation of the spiral blades squeezes and breaks up the plant material, preventing clumping and reducing the extraction and separation speed on the inner side, thus facilitating the uniform extraction and separation of the raw material by the solvent.
[0022] 2. With solenoid valve number two closed and solenoid valve number three open, the solvent is introduced into the water pipe through solenoid valve number three. Then, the circulation pump runs, causing the solvent to be discharged from the three-way pipe number one. Solenoid valve number two is opened and solenoid valve number three is closed, allowing the solvent to circulate into the filter cartridge, increasing the pressure of the solvent flushing the raw material and accelerating the extraction speed.
[0023] 3. After extraction is complete, the electric push rod extends, causing the baffle to move out of the feed pipe and into the receiving frame. Then the spiral blades rotate, squeezing the waste material out of the feed pipe, thus allowing the waste material to be discharged quickly. Attached Figure Description

[0029] 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.
[0030] Please see Figure 1-4In this embodiment of the present invention, a low-temperature extraction device for plant extracts includes an extraction component 3 disposed inside an extraction chamber 1. The extraction component 3 includes a filter cartridge 301 fixedly installed inside the extraction chamber 1 by a bracket. A water pipe 302 is movably disposed inside the filter cartridge 301. A spiral blade 303 is fixedly installed on the outer surface of the water pipe 302. A circulation component 2 is fixedly installed on one side of the extraction chamber 1. The circulation component 2 includes a circulation pump 201. One end of the circulation pump 201 is fixedly connected to a connecting pipe 202. A feeding component 4 is fixedly installed on the lower surface of the filter cartridge 301. A No. 1 three-way pipe 101 is fixedly embedded in the lower surface of the extraction chamber 1. A No. 1 solenoid valve 102 is fixedly installed at one end of the No. 1 three-way pipe 101. When the No. 1 solenoid valve 102 is opened, the extract is discharged. When the No. 1 solenoid valve 102 is closed, the extract is circulated through the circulation component 2.
[0031] Specifically, the extraction component 3 causes the solvent to precipitate the extract from the raw material. The solvent is circulated through the circulation component 2, which increases the pressure of the solvent flushing the raw material and at the same time makes the extract evenly mixed into the solvent. Then, the residual waste is discharged through the feeding component 4.
[0032] Example 1
[0033] like Figure 2 and Figure 3 As shown, in this embodiment, multiple water distribution holes 304 are equidistantly opened on the outer surface of the water pipe 302. A motor 305 is fixedly installed on the upper end of the extraction chamber 1 by a bracket. Two meshing gears 306 are fixedly installed on the output end of the motor 305 and the outer surface of the water pipe 302. A feed pipe 307 is fixedly embedded in the upper end of the filter cartridge 301 and the feed pipe 307 is fixedly inserted through the extraction chamber 1.
[0034] In this embodiment, the raw material is fed into the feed pipe 307, then the feed pipe 307 is sealed. The motor 305 operates, and through the meshing transmission of the gear 306, the water pipe 302 drives the spiral blade 303 to rotate, squeezing the raw material downwards and extruding the extract from the raw material. The motor 305 is then reversed, causing the spiral blade 303 to rotate in the opposite direction, pulling the raw material upwards and breaking it up. Then, the solvent is sprayed out from the water separator 304 at a certain pressure, allowing the high-pressure solvent to flush the raw material and quickly break it up. The solvent then carries the precipitated extract out of the filter cartridge 301 and into the extraction chamber 1. Thus, by feeding the plant raw material into the filter cartridge 301, the solvent impacts the plant raw material at a certain pressure, accelerating the extraction speed of the extract. Furthermore, the forward and reverse rotation of the spiral blade 303 squeezes and breaks up the plant raw material, preventing the raw material from clumping and causing a decrease in the extraction and separation speed of the raw material on the inner side, thus facilitating the uniform extraction and separation of the raw material by the solvent.
[0035] like Figure 2As shown, in this embodiment, the other end of the circulation pump 201 is fixedly connected to the other end of the first three-way pipe 101. A second solenoid valve 203 is fixedly installed at one end of the first three-way pipe 101, a second three-way pipe 204 is fixedly installed at one end of the second solenoid valve 203, and a third solenoid valve 205 is fixedly installed at one end of the second three-way pipe 204. The water pipe 302 passes through the extraction chamber 1 and is rotatably connected to the extraction chamber 1. A rotary joint 206 is fixedly installed at the upper end of the water pipe 302, and one end of the rotary joint 206 is fixedly connected to the second three-way pipe 204.
[0036] In practice, solenoid valve 203 is closed and solenoid valve 205 is opened, allowing the solvent to enter the water pipe 302 through solenoid valve 205. Then, the circulation pump 201 is activated, allowing the solvent to be discharged from the three-way pipe 101. Solenoid valve 203 is opened and solenoid valve 205 is closed, allowing the solvent to circulate into the filter cartridge 301, increasing the pressure of the solvent flushing the raw material and accelerating the extraction speed.
[0037] Example 2
[0038] Based on Example 1, in order to compensate for the problem that the waste inside the filter cartridge 301 is not easy to discharge.
[0039] like Figure 3 and Figure 4 As shown, in this embodiment, the feeding assembly 4 includes: a feeding pipe 401 fixedly embedded in the lower surface of the filter cartridge 301, a storage frame 402 fixedly embedded in the outer surface of the feeding pipe 401, and a baffle 404 slidably connected to the inside of the storage frame 402; the feeding pipe 401 fixedly penetrates the lower surface of the extraction chamber 1, the storage frame 402 fixedly penetrates the outer surface of the extraction chamber 1, and an electric push rod 403 is fixedly installed inside the storage frame 402, the output end of the electric push rod 403 being fixedly connected to the baffle 404 via a connecting rod.
[0040] In practice, after extraction is completed, the electric push rod 403 extends, causing the baffle 404 to move out of the feed pipe 401 and into the storage frame 402. Then the spiral blade 303 rotates, squeezing the waste material out of the feed pipe 401, thereby allowing the waste material to be discharged quickly.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
