Description

Technical Field

[0001] This utility model relates to the field of edible fungi production technology, and in particular to an edible fungi extraction and mixing device. Background Technology

[0002] Edible fungi are rich in polysaccharides, proteins, amino acids, sterols, and various bioactive components, possessing extremely high nutritional and medicinal value. In modern food, health product, and pharmaceutical industries, extraction techniques are often used to transfer the active ingredients from edible fungi into solvents (such as water and ethanol) to prepare oral liquids, concentrated juices, or further process them into various products. The first step in this process is to thoroughly mix and stir the edible fungi powder with a specific solvent, aiming to maximize the dissolution of soluble substances in the fungi powder to form a mixed extract.

[0003] Currently, the core structure of the extraction and mixing devices commonly used in the industry is usually a mixing tank with a stirring mechanism. During operation, a fixed amount of edible fungus powder and dissolving solution are added into the tank together. The blades on the drive shaft rotate to mix the solid and liquid phases, thereby achieving mass transfer and component dissolution.

[0004] However, this traditional mixed extraction method has a significant drawback that directly affects the quality of the extract and the efficiency of subsequent processes: after the stirring extraction is completed, a large amount of undissolved solid residue remains in the mixture. This residue mainly originates from cell wall fragments of edible fungi, dietary fiber, and other insoluble components. Because existing mixing devices are designed for a single function—mixing rather than separation—these insoluble residues are discharged along with the extract rich in active ingredients when mixing is complete and the material is discharged.

[0005] Suspended residues in the mixture can make the liquid cloudy, affecting the clarity and appearance of the product. More importantly, these residues may continue to release substances that affect flavor and stability during later storage or processing, and may even become a breeding ground for microorganisms, reducing the commercial value and safety of the product.

[0006] To obtain a pure extract, the discharged mixture must undergo one or more additional filtration, sedimentation, or centrifugation processes to remove solid residues. This not only requires additional filtration equipment (such as vibrating screens, plate and frame filters, centrifuges, etc.) but also significantly increases the number of steps and complexity in the production process. Operators need to transfer materials, start and stop equipment, and clean the equipment; the entire process is cumbersome, time-consuming, and significantly increases labor costs and equipment investment.

[0007] Furthermore, transferring the mixture from the mixing tank to the separation equipment not only increases the number of operational steps but also raises the risk of contamination of the material. Additionally, during transfer and filtration, some valuable extract will inevitably adhere to and be lost. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, this utility model provides an edible fungus extraction and mixing device. This design effectively solves the problem that the two key processes of mixing and solid-liquid separation in the edible fungus extraction and mixing device are completely separated, resulting in a discontinuous production process, low efficiency, and poor controllability of the final product quality.

[0009] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a support frame, a mixing tank fixedly connected to the support frame, a hopper fixedly connected to the upper end of the mixing tank, a first connecting pipe connecting the hopper and the mixing tank, a liquid storage tank fixedly connected to the support frame, a second connecting pipe connecting the liquid storage tank and the mixing tank, a mixing chamber provided inside the mixing tank, a stirring roller provided in the mixing chamber, a filter plate provided below the mixing chamber, a liquid outlet chamber provided below the mixing chamber, a liquid outlet pipe provided on the side of the liquid outlet chamber, and the liquid outlet pipe fixedly connected to the mixing tank.

[0010] Preferably, a spiral feeding roller is rotatably connected inside the hopper, and a first pulley group is coaxially connected to the spiral feeding roller.

[0011] Preferably, the hopper is provided with a V-shaped trough, and the spiral feeding roller is located at the bottom of the trough.

[0012] Preferably, the stirring roller includes a drive shaft, which is rotatably connected to the mixing chamber. A second pulley set is fixedly connected to the outside of the drive shaft, and a spiral blade is fixedly connected to the inside of the drive shaft.

[0013] Preferably, there are two sets of helical blades, and the two sets of helical blades rotate in opposite directions on the drive shaft.

[0014] Preferably, two sets of symmetrically distributed scraper discs are fixedly connected to the drive shaft, and the two scraper discs respectively abut against the two side walls of the mixing tank.

[0015] Compared with the prior art, the outstanding advantages of this utility model are: This application installs a filter plate between the stirring chamber and the liquid outlet chamber. The filter plate separates undissolved solid particles from the mixture, thereby ensuring the quality of the finished mixture and avoiding the problems of "residue being discharged with the mixture, affecting quality" and "the mixture requiring an additional sieving process".

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0023] Please see the appendix Figure 1-5 This embodiment discloses an edible fungus extraction and mixing device, comprising a support 1, a mixing chamber 2, a hopper 3, and a storage tank 5. The mixing chamber 2 is fixed to the support 1 and has a mixing cavity 7 inside. A stirring roller 8 is installed inside the mixing cavity 7, and a filter plate 9 is located below the mixing cavity 7. A liquid outlet cavity 10 is formed below the filter plate 9, and a liquid outlet pipe 11 is connected to the side wall of the liquid outlet cavity 10. The hopper 3 is connected to the mixing chamber 2 via a first connecting pipe 4 for adding fungal powder; the storage tank 5 is connected to the mixing chamber 2 via a second connecting pipe 6 for supplying the dissolving solution. This device achieves integrated operation of feeding, mixing, extraction, and preliminary solid-liquid separation.

[0024] The support frame 1 serves as the overall support structure, with its bottom supported by six vertical legs. Furthermore, to ensure the upper part of the support frame 1 is placed horizontally, these six legs are adjustable, allowing for easy adjustment of the support frame 1's level. A mixing tank 2 is fixedly connected to the support frame 1; this mixing tank 2 is the core area for the extraction and mixing reaction. At the upper end of the mixing tank 2, a hopper 3 is fixedly connected via a first connecting pipe 4. The hopper 3 is used for quantitatively and controllably adding edible fungus powder. Simultaneously, a storage tank 5 is also fixedly connected to the support frame 1. This storage tank 5 is connected to the mixing tank 2 via a second connecting pipe 6, and its function is to precisely deliver the extraction solvent (such as water or ethanol solution) into the mixing tank 2.

[0025] The mixing chamber 2 contains a mixing cavity 7, within which the solid-liquid two-phase mixing and the dissolution of active ingredients take place. A stirring roller 8 is installed within the mixing cavity 7 to provide forced shearing and convection, promoting mixing. Below the mixing cavity 7 is a removable filter plate 9. The filter plate 9 has a semi-annular structure, which increases the liquid flow area within a limited space, while ensuring better liquid flow within the mixing cavity. This filter plate 9 is one of the key components of this invention in solving the problems described in the background art; its pore size can be selected according to the required powder fineness and solution requirements. Below the filter plate 9, an independent outlet cavity 10 is formed. An outlet pipe 11 is fixedly connected to the side wall of the outlet cavity 10 for discharging the filtered, clarified extract. Similar to existing pipe structures, the outlet pipe 11 is equipped with a controllable valve structure.

[0026] The working process of this core structure is as follows: After the edible fungus powder and the dissolving liquid are fully mixed and extracted in the mixing chamber 7 by the stirring roller, the mixture flows through the filter plate 9 under the action of gravity. At this time, the undissolved solid residue is effectively trapped in the mixing chamber 7 by the filter plate 9, while the clear, high-quality extract enters the outlet chamber 10 and is collected through the outlet pipe 11.

[0027] The hopper 3 preferably has a V-shaped trough 14 inside. This V-shaped structure can effectively guide the powdery material to concentrate towards the bottom center, preventing it from accumulating in the corners. At the bottom of the trough 14, a spiral feeding roller 12 is rotatably connected. The spiral feeding roller 12 is connected to a first pulley assembly 13 installed outside the hopper 3 via a rotating shaft at one end. The first pulley assembly 13 is driven by a drive motor (not shown in the figure).

[0028] Its beneficial effects are as follows: By controlling the number of rotations of the screw feeder 12, precise and quantitative feeding of edible fungus powder can be achieved, avoiding the problems of dust and inaccurate measurement caused by manual feeding. At the same time, the screw conveyor is a closed conveying method, which can effectively prevent the material from absorbing moisture or becoming contaminated, ensuring the hygiene and controllability of the feeding process. Furthermore, the stirring roller includes a drive shaft 801, which is rotatably connected to the cover of the mixing chamber 2 via bearings. A second pulley set 802 is fixedly connected to the outside of the drive shaft 801, and this second pulley set 802 is driven by an independent motor, thereby providing rotational power to the stirring roller. Inside the drive shaft 801, helical blades 803 are fixedly connected. As a key optimization, there are two sets of helical blades 803, and the two sets of helical blades 803 rotate in opposite directions on the drive shaft 801.

[0029] When the drive shaft 801 rotates, two sets of oppositely rotating helical blades 803 work simultaneously with the drive shaft 801. One set of helical blades 803 generates a downward axial thrust, forcing the upper liquid and particles downward; while the other set generates an upward axial thrust, forcing the lower material upward. This creates a strong axial convection circulation within the mixing chamber 7. This turbulent flow field greatly enhances the mass transfer process between the solid and liquid phases, ensuring more thorough contact between the edible fungus powder and the dissolving liquid, and more complete dissolution of the effective components. It also effectively prevents the powder from floating on the liquid surface or settling and clumping at the bottom, solving the mixing dead zone problem that may exist in traditional stirring. Furthermore, two sets of symmetrically distributed scraper discs 804 are fixedly connected to the drive shaft 801. The radial outer edges of these two scraper discs 804 are designed to fit tightly or slightly elastically against the two inner sidewalls on the left and right sides of the mixing chamber 2.

[0030] During prolonged mixing and extraction, fine fibers or sticky substances easily adhere to the inner wall of the mixing chamber 2, forming a "wall-hanging" phenomenon. These wall-hanging substances not only waste material, but their long-term accumulation can also become a source of microbial growth and affect the effective volume and heat transfer efficiency of the mixing chamber 2. The scraper disc 804, rotating with the drive shaft 801, can promptly and effectively scrape off the material adhering to the inner walls on both sides of the mixing chamber 2, allowing it to return to the main mixing flow for circulation. This ensures uniform mixing, improves yield, and reduces cleaning and maintenance workload.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
