Description

Technical Field

[0001] This utility model relates to the field of industrial hemp extraction technology, and in particular to a decarboxylation device for industrial hemp extract. Background Technology

[0002] Industrial hemp is a type of cannabis with a tetrahydrocannabinol (THC) content of less than 0.3%, primarily used for industrial purposes, and is fundamentally different from recreational cannabis (THC > 0.5%). Industrial hemp: THC < 0.3%, no psychoactive components, mainly utilized for its fiber, seeds, flowers, leaves, and biomass. It is legally cultivated in over 50 countries worldwide, with China accounting for half of the global cultivation area (primarily in Yunnan and Heilongjiang provinces). Current decarboxylation equipment for industrial hemp extracts mainly utilizes reaction vessels.

[0003] Traditional reactors lack an extraction mechanism, making it impossible to remove the carbon dioxide generated during the decarboxylation of industrial hemp extracts. This leads to a continuous presence of carbon dioxide during the decarboxylation reaction, which accumulates on the material surface and within the container, creating a "gas barrier." This not only hinders the separation of the generated CBD from the material but, more importantly, according to the principle of chemical equilibrium, an increase in product concentration inhibits the forward reaction, resulting in incomplete decarboxylation. Therefore, an extraction mechanism is necessary to ensure proper decarboxylation within the reactor. Utility Model Content

[0004] This invention provides a decarboxylation device for industrial hemp extract, which solves the structural problem mentioned above where carbon dioxide appears during the decarboxylation of industrial hemp extract. If the carbon dioxide is not extracted, it will inhibit the forward reaction and lead to incomplete decarboxylation.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A decarboxylation device for industrial hemp extract includes a decarboxylation reactor. A vacuum pump is installed at the top of the decarboxylation reactor, and a stirring mechanism is installed inside the reactor. A jacket is installed outside the reactor.

[0006] The beneficial effects of this utility model are as follows: The decarboxylation reactor mainly facilitates the storage of industrial hemp extract for internal chemical reactions. The pumping mechanism can extract carbon dioxide gas generated during the internal reaction, the stirring mechanism can accelerate the internal chemical reaction, the jacket allows the hot liquid introduced by the inlet pipe to conduct heat to the decarboxylation reactor, thereby heating the reactants inside the reactor, the drain pipe facilitates the discharge of the heat-exchanged liquid, the pump facilitates the extraction of gas, the connecting pipe facilitates the connection to the vacuum buffer tank, the first valve facilitates the control of the flow rate inside the connecting pipe, the vacuum buffer tank, as a large cavity, can prevent foreign objects from entering during large reactions, protecting the operation of the pumping pump, the suction pipe facilitates the extraction of gas and its delivery to the interior of the vacuum buffer tank, the second valve facilitates the control of the gas flow rate inside the suction pipe, and the check mechanism facilitates the prevention of gas backflow.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a spring is provided at the top of the disc, a support frame is provided at the top of the spring, the support frame is located inside the suction cylinder, and a suction port is provided at the bottom of the suction cylinder.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the spring can use its elasticity to push the disc to squeeze and seal the suction port, which plays a role in pre-tightening; the support frame can support one side of the spring; and the suction port facilitates the inflow of gas inside the decarboxylation reactor.

[0014] Furthermore, a scraper is provided on one side of each of the connecting rods, and multiple rotating rods are arranged in a linear equidistant array on both sides of the stirring rod near the bottom.

[0015] The beneficial effects of adopting the above-mentioned further scheme are: the scraper can be attached to the inner cavity of the decarboxylation reactor, which can scrape off the reactants during the reaction, ensuring the normal operation of the internal reaction, and the rotating rod can rotate the stirring blade.

[0016] Furthermore, each of the multiple rotating rods is provided with a stirring blade on one side, and a speed-regulating motor is provided at the top of the stirring rod. The speed-regulating motor is located at the top of the decarboxylation reactor, and a bearing body is provided on the inner top surface of the decarboxylation reactor.

[0022] The following is in conjunction with the appendix Figure 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. Example

[0023] like Figure 1-4 As shown, this utility model discloses a decarboxylation device for industrial hemp extract, comprising a decarboxylation reactor 1, an exhaust mechanism 2 at the top of the reactor 1, a stirring mechanism 3 inside the reactor 1, and a jacket 4 outside the reactor 1. A liquid inlet pipe 5 is located on one side of the jacket 4, and a liquid outlet pipe 6 is located on the other side of the jacket 4. The liquid inlet pipe 5 connects to an external hot liquid pipe, allowing hot liquid to enter the jacket 4. The liquid flows within the jacket 4, transferring heat to the reactants inside the reactor 1, thus heating the reactants. The heat-exchanged liquid is discharged through the liquid outlet pipe 6. To allow the hot liquid to continuously enter the heat treatment reactants, the gas extraction mechanism 2 includes a gas extraction pump 21. The suction end of the gas extraction pump 21 is connected to a connecting pipe 22. A first valve 23 is provided at the top of the connecting pipe 22, which facilitates the control of the internal flow of the connecting pipe 22. A vacuum buffer tank 24 is connected to one side of the connecting pipe 22, and a suction pipe 25 is provided on one side of the vacuum buffer tank 24. A second valve 26 is provided at the top of the suction pipe 25, which can control the internal flow of the suction pipe 25. A check valve 27 can prevent the extracted gas from flowing back into the decarboxylation reactor 1. Example

[0024] like Figure 1-4As shown, the check valve mechanism 27 includes a suction cylinder 271 and a disc 272. The suction cylinder 271 is located at the bottom of the suction pipe 25. A spring 273 is located at the top of the disc 272, and a support frame 274 is located at the top of the spring 273. The support frame 274 is located inside the suction cylinder 271 and supports the spring 273. The spring 273 uses its elasticity to support the disc 272, giving the disc 272 a pre-tight force. This allows the disc 272 to seal the suction port 275 below the suction cylinder 271. The stirring mechanism 3 includes a stirring rod 31. Multiple connecting rods 32 are arranged linearly and equidistantly on both sides of the stirring rod 31. A scraper 33 is located on one side of each connecting rod 32. Multiple rotating rods 34 are arranged linearly and equidistantly on both sides of the stirring rod 31 near the bottom. Stirring blades 35 are provided on one side of the stirring rod 31, and a speed-regulating motor 36 is provided at the top of the stirring rod 31. The speed-regulating motor 36 is located at the top of the decarboxylation reactor 1. A bearing body 37 is provided on the inner top surface of the decarboxylation reactor 1. The stirring rod 31 passes through the bearing body 37 and is connected to the speed-regulating motor 36. The speed-regulating motor 36 can rotate the stirring rod 31, which can also rotate the connecting rod 32 and the scraper 33, allowing the scraper 33 to fit into the interior of the decarboxylation reactor 1 and scrape the material on the inner wall of the decarboxylation reactor 1 back into the main fluid in the center of the reactor. This prevents the material from staying on the wall for a long time and causing coking. The stirring rod 31 can also easily rotate the rotating rod 34 and the stirring blades 35, which can make the heated material inside the reactor evenly stirred and prevent uneven heating of the reactants inside the reactor.

[0025] Working principle: When decarboxylation of industrial hemp extract is required, the reactants are first allowed to enter the interior through the feed port on the decarboxylation reactor 1. The inlet pipe 5 is connected to the hot liquid conveying device, and the outlet pipe 6 is connected to the collection device. The hot liquid can be transported to the interior of the jacket 4 through the inlet pipe 5. The hot liquid inside the jacket 4 can heat the reactants inside the decarboxylation reactor 1. The liquid after heat exchange can be discharged through the outlet pipe 6. In this way, hot liquid can be continuously transported to conduct heat to the reactants and accelerate the chemical reaction of the reactants. When it is necessary to stir the internally heated reactants, the speed-regulating motor 36 drives the stirring rod 31 to rotate, which in turn drives the connecting rod 32 and the scraper 33 to rotate. The scraper 33 can fit into the inside of the decarboxylation reactor 1 to scrape the material on the inner wall of the decarboxylation reactor 1 and return it to the main fluid in the center of the reactor. This prevents the material from staying on the wall for a long time and causing coking. The stirring rod 31 can also easily drive the rotating rod 34 and the stirring blade 35 to rotate, which can make the internally heated material evenly stirred and prevent uneven heating of the internal reactants. When the reactants inside the decarboxylation reactor 1 produce a large amount of carbon dioxide, the vacuum pump 21, acting as a vacuum source, is connected to the vacuum buffer tank 24 via the connecting pipe 22, forming the main vacuum channel. Valve 23 controls the gas flow between the vacuum pump 21 and the buffer tank, enabling start-up and shutdown of the pumping process. The vacuum buffer tank 24, acting as a pressure buffer device, balances the pressure fluctuations generated by the vacuum pump 21 during operation, preventing excessively high or low local vacuum levels from affecting the uniformity of decarboxylation. It also prevents excessively vigorous reactions that could cause liquid ejection, thus preventing damage to the vacuum pump 21. The vacuum pump 25 is connected to the check mechanism 27 via the suction pipe 25, forming a gas extraction path from the tank to the reaction chamber. The bottom of the suction pipe 25 is connected to the check mechanism 27, and finally, it connects to the inside of the decarboxylation reactor 1 via the suction port 275, achieving directional extraction of gas from the reaction chamber. The check valve mechanism 27 has the suction cylinder 271 as its main structure, and internally it is equipped with a disc 272, a spring 273, and a support frame 274 to form a one-way valve structure. When the vacuum pump 21 is working, the gas in the reaction chamber enters the suction cylinder 271 through the suction port 275. Under the action of negative pressure, the disc 272 overcomes the elastic force of the spring 273 and moves upward, allowing the gas to enter the suction pipe 25 through the gap of the support frame 274. When the vacuum pump 21 stops or the system pressure is balanced, the spring 273 pushes the disc 272 to reset, tightly adhering to the inner wall of the suction cylinder 271, sealing the suction port 275, preventing backflow of external gas or gas in the reaction chamber, and maintaining the stability of the vacuum environment.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way.

However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
