[0032] As a specific embodiment, as Figure 1 As a specific embodiment, as

[0033] In this embodiment, in response to the requirement that the solution in the bioreaction is repeatedly and evenly contacted and reacted with the reactants, an external circulation pipeline is designed. The circulation pump 5 provides kinetic energy to extract the solution from the upper part of the reaction tank 1 and spray it from the lower part into the bioreaction zone. As a result, the biomass in a suspended state can repeatedly and evenly contact and react with the solution, and the effective ingredients in the biomass are dissolved into the extract to the maximum extent, thereby obtaining higher economic benefits. At the same time, the impurity content and composition are less affected, and no difficulties are caused in subsequent purification.

[0034] As a preferred embodiment, Figure 1 On the basis of the above embodiment, the water inlet area, the biological reaction area and the water outlet area are divided by the upper filter screen 2 and the lower filter screen 10 built into the reaction tank 1. The area between the upper filter screen 2 and the top wall of the reaction tank 1 is set as the water inlet area, the area between the upper filter screen 2 and the lower filter screen 10 is set as the biological reaction area, and the area between the lower filter screen 10 and the bottom wall of the reaction tank 1 is set as the water outlet area; the upper filter screen 2 and the lower filter screen 10 are arranged horizontally, which can be horizontal or slightly inclined; the upper filter screen 2 and the lower filter screen 10 are firmly fixed to the inner wall of the reaction tank 1. Preferably, the size of the upper and lower filter screens is adapted to the inner diameter of the reaction tank 1, so that there are no protrusions or redundant parts, and the reaction space in the tank is expanded; in some specific embodiments, the upper and lower filter screens are screwed to the inner wall of the reaction tank 1 through several mounting holes on the peripheral edge, or the edge of the filter screen is directly welded to the inner wall of the reaction tank 1.

[0035] In some preferred embodiments, the upper filter 2 and lower filter 10 are evenly distributed with a plurality of filter holes. These pores are capable of retaining the biomass while allowing the post-reaction extract to pass through and evenly spray the solution. A portion of the solution is returned to the bottom of the reactor 1 via an external circulation pipeline. It is then evenly sprayed into the bioreaction zone via the lower filter 10, suspending the biomass and allowing it to fully react with the solution. The completed extract is then discharged from the outlet pipe 7 to the next process. During the pumping process of the circulation pump 5, the solution flows out through the upper filter 2, retaining the biomass within the bioreaction zone.

[0036] In this embodiment, the upper and lower filters are designed to divide the reaction tank 1 into a water inlet area, a biological reaction area and a water outlet area. The upper and lower filters can simultaneously play the role of evenly spraying and intercepting biomass materials and allowing the extract to pass through. The biomass material loss is small, the biological reaction is sufficient and thorough, the product yield is high, and the economic benefits are significant. The filter of this application is easy to obtain, the configuration cost is low, the installation is convenient, and the structure inside the reaction tank 1 is compact, without increasing the space occupied by additional equipment and pipelines, significantly improving the biological reaction efficiency and reducing the overall floor area.

[0037] As a preferred embodiment, Figure 1 A liquid storage tank 4 is connected in series to the external circulation pipeline. The solution stored in the liquid storage tank 4 is returned to the bottom of the reaction tank 1 in a jet-like manner by the kinetic energy provided by the circulation pump 5.

[0038] Specifically, the external circulation pipeline includes an upper circulation pipe 3 and a lower circulation pipe 6. The inlet of the upper circulation pipe 3 is connected to the circulating liquid outlet of the water inlet area, and the outlet is connected to the inlet of the circulation pump 5; the inlet of the lower circulation pipe 6 is connected to the outlet of the circulation pump 5, and the outlet is connected to the circulating liquid inlet of the water outlet area; the connection between the pipelines is fixed with flanges.

[0039] The liquid storage tank 4 of this embodiment is used to buffer the solution drawn out from the top of the reaction tank 1 and to make the amount and flow rate of the solution circulating to the reaction tank 1 stable and easy to control.

[0040] Preferably, both the reaction tank 1 and the liquid storage tank 4 are equipped with support bases, which create a space for accommodating the pipelines between the bottoms of the reaction tank 1 and the liquid storage tank 4 and the ground. This effectively stores the pipelines, making the overall reaction equipment layout compact, saving floor space, and preventing pipeline wear and tear that could even cause interruptions to the biological reaction.

[0041] As a preferred embodiment, Figure 1 A high-pressure nozzle 9 is installed on the lower side wall of the biological reaction zone. The inlet of the high-pressure nozzle 9 is connected to the water source or the external circulation pipeline, and the outlet is arranged toward the biomass material, which is used to further impact the biomass material, so that it is stably in a suspended state and promotes the efficient progress of the plant extraction reaction.

[0042] In some preferred embodiments, multiple high-pressure nozzles 9 are evenly distributed along the circumference of the reaction tank 1, so that the water flow for auxiliary fluidization is evenly distributed around the biomass, achieving sufficient disturbance and keeping the biomass in a stable suspension state.

[0043] In some specific embodiments, a discharge port 8 is provided on the side wall of the bioreactor area for storing and taking out biomass materials, making the operation convenient.

[0044] In the above embodiment, the reaction tank 1 and the liquid storage tank 4 are both made of stainless steel, which increases the service life of the tanks.

[0045] In order to have a clearer understanding of the technical solution and technical effects of this application, the following specific process examples are provided:

[0046] During production, the extract is placed into the reaction tank 1 through the discharge port 8, and water or other solutions are added through the water inlet. Excess solution enters the liquid storage tank 4 through the upper circulation pipe 3. The circulation pump 5 is turned on, and the solution enters the reaction tank 1 through the lower circulation pipe 6. It is sprayed onto the extract through the lower filter 10, so that the extract forms a suspended state, which is conducive to a uniform and thorough reaction. As the solution increases, it will overflow through the upper filter 2 and return to the liquid storage tank 4, forming a cycle. To ensure uniform stirring, two high-pressure nozzles 9 are provided at the bottom to inject high-pressure solution for further stirring. After the reaction is completed, the solution is discharged from the water outlet to the next process, and the extracted reactant residue is discharged from the discharge port 8.

[0047] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
