Description

Technical Field

[0001] This utility model relates to the field of plant extract research and is a plant extract preparation device. Background Technology

[0002] Plant extracts are products made from plants as raw materials. Through physical and chemical extraction and separation processes, specific or multiple active ingredients are selectively extracted and concentrated without altering their structure, according to the intended use of the extracted product. Plant extracts are diverse, with over 300 varieties currently used in industrial extraction. They are important intermediate products widely used in the food and beverage, condiment, pharmaceutical, health product, nutritional supplement, cosmetic, and feed additive industries.

[0003] There are several traditional methods for preparing plant extracts, including solvent extraction, which selects solvents based on the solubility of various components in the plant material, choosing those with high solubility for active ingredients and low solubility for those not needed to be dissolved, thus extracting the effective components from the plant; maceration, which involves crushing the plant material into small pieces, placing them in a suitable container, adding a suitable solvent (such as ethanol, dilute alcohol, or water), and macerating the plant material to dissolve its components; percolation, which involves placing the plant material powder in a percolator, continuously adding new solvent to allow it to permeate the material, and then allowing the extract to flow out from the bottom of the percolator; and decoction, which is the earliest traditional extraction method used in my country. The containers used are generally earthenware, sand pots, or copper or enamelware; iron pots are not recommended as they may discolor the liquid. When heating over a direct flame, it is best to stir frequently to prevent the plant material from overheating and scorching. These methods of preparing plant extracts are inefficient. Summary of the Invention

[0004] To address the low efficiency of existing plant extract preparation methods, we propose a plant extract preparation device. A mechanical device rotates the extraction cup assembly forward / backward by 180°. With the extraction cup assembly upright, steam is introduced, heating the plant material. After heating, the steam input is cut off, and the extraction cup is sealed and pressurized for a period before being released. The pressure change inside the extraction cup assembly accelerates the penetration and diffusion of soluble substances. The extraction cup assembly is then sealed again and rotated backward by 180°, placing it in an inverted state. The plant material is completely immersed in the solvent, and the plant extract dissolves in the solvent. The extraction cup assembly then returns to its upright position, completing one extraction cycle. The preparation of the plant extract is completed through several extraction cycles.

[0005] To achieve the above extraction action, a plant extract preparation device comprises a base, a swing arm power assembly, an active swing arm assembly, a driven swing arm assembly, a driven swing arm bearing seat, a tilting table, a pressure head sealing assembly, an extraction cup assembly, and a downward pressure power assembly. The pressure head downward pressure power assembly is also included.

[0006] The swing arm power assembly is installed on the upper surface of the left side of the base. Two driven swing arm bearing seats are respectively installed on the front right side and the rear right side of the upper surface of the base. The lower ends of the two active swing arm assemblies pass through the drive shaft of the swing arm power assembly.

The two driven swing arm assemblies are sandwiched between the two driven swing arm bearing seats. The extraction cup assembly is stuck in the semi-circular groove on the left side of the tilting table. The pressure head sealing assembly passes through the large circular hole on the upper side of the tilting table and presses down to fix the extraction cup assembly. The power gear of the pressure head pressing power assembly passes through the hole on the right side of the tilting table and is fixed to the right side of the tilting table. The drive gear meshes with the rack and pinion housing of the pressure head, and the forward / reverse rotation of the drive gear drives the pressure head sealing assembly to rise / fall.

The active swing arm drive shaft passes through the active swing arm, the driven synchronous pulley, and the tilting table in sequence. The active swing arm drive shaft is connected to the driven synchronous pulley and the tilting table respectively. The driven synchronous pulley and the active synchronous pulley are connected by a synchronous belt. The rotation of the drive shaft drives the active swing arm drive shaft through the active synchronous pulley, the synchronous belt, and the driven synchronous pulley to rotate the tilting table forward / backward.

[0009] The driven swing arm assembly consists of a driven swing arm, an upper fixed shaft of the driven swing arm, and a lower fixed shaft of the driven swing arm. The lower fixed shaft of the driven swing arm passes through the driven swing arm bearing seat. The driven swing arm and the lower fixed shaft of the driven swing arm are fixed to the driven swing arm. The driven swing arm drives the lower fixed shaft of the driven swing arm to rotate around the driven swing arm bearing seat. The upper fixed shaft of the driven swing arm passes through the driven swing arm and the tilting table. The upper fixed shaft of the driven swing arm is fixed to the tilting table. The swinging of the driven swing arm drives the tilting table to tilt forward / backward.

The steam inlet connector and solvent inlet connector are installed on the upper end face of the pressure head rack housing, connecting to the solvent / vapor channel formed by the elongated holes in the pressure head rack housing. The guide key connects the pressure head rack housing and the tilting platform. The micro stepper motor is installed inside the pressure head rack housing. The stepper motor mounting cover presses down to tighten the micro stepper motor. The positioning button is installed directly above the micro stepper motor. The sealing valve cover is fixed to the bottom of the sealing valve lever. The sealing valve lever passes through the sealing valve rubber ring from the bottom of the sealing valve body and is inserted into the micro stepper motor. The sealing valve lever has threads on the outside. The micro stepper motor is internally connected to the sealing valve lever through a threaded pair. The forward / reverse rotation of the micro stepper motor causes the sealing valve lever to move up / down, driving the sealing valve cover to open / close the channel for steam / solvent to enter the extraction cup assembly. When the sealing valve cover closes the channel for steam / solvent to enter the extraction cup assembly, the sealing valve lever presses up to tighten the positioning button, sending a positioning signal.

[0013] This utility model, employing the above-mentioned technical solution, has the following beneficial effects: With the tilting table in the upright position, plant materials are placed in the material bin. The downward-pressing reduction motor rotates, driving the power gear to lower the pressure head sealing assembly, pressing the extraction cup assembly into the semi-circular groove of the tilting table. The micro stepper motor rotates forward, driving the sealing valve cover to lower, opening the solvent / steam inlet channel into the extraction cup assembly. The solvent enters the extraction cup assembly through the solvent inlet connector, completing the preparation work for extracting the plant materials. Steam enters the extraction cup assembly through the steam inlet connector, heating the plant materials and increasing the internal pressure of the extraction cup assembly. After a period of time, the micro stepper motor reverses, driving the sealing valve cover to rise, closing the steam / solvent inlet channel into the extraction cup assembly and cutting off the steam input. After a period of pressure holding, the micro stepper motor quickly rotates forward, driving the sealing valve cover to lower, opening the solvent inlet channel. Steam enters the extraction cup assembly, relieving internal pressure. A micro-stepping motor reverses, causing the sealing valve to rise and close the solvent / steam inlet. The tilting platform rotates 180° to the right, inverting the extraction cup assembly and immersing the plant material completely in the solvent. The plant extract dissolves rapidly. The tilting platform then rotates 180° to the left, returning to its upright position and aligning the extraction cup assembly. The micro-stepping motor rotates forward, causing the sealing valve to descend and opening the solvent / steam inlet, completing one cycle. After several cycles, the extraction of the plant material is complete. Throughout the extraction process, the plant material and solvent remain only within the extraction cup assembly. Simply replace the extraction cup assembly with the pre-filled plant material to quickly begin the next extraction operation. Attached Figure Description
