Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation tank technology, and in particular to a liquid spawn fermentation tank for Oyster mushrooms. Background Technology
[0002] Oyster mushroom, also known as miniature oyster mushroom, lung-shaped oyster mushroom, yellow-white oyster mushroom, ring-stalked oyster mushroom, and small oyster mushroom, differs from the common phoenix tail mushroom in its smaller size, with a stem of 5-6 cm and a cap diameter of less than 3 cm. Oyster mushroom is actually a more commercially-oriented name for the phoenix tail mushroom; it refers to the immature fruiting body of the phoenix tail mushroom. Oyster mushrooms are not only crisp and tender with low fiber content, offering an excellent texture and delicious flavor, but they are also rich in nutrients. The polysaccharides they contain have been proven to have anti-tumor properties, and their fruiting bodies are rich in high-quality fungal protein, 17 kinds of amino acids needed by the human body, and various trace elements. It is a rare and highly nutritious edible fungus, renowned as the "ultimate mushroom."
[0003] The cultivation of oyster mushrooms requires the use of fermentation tanks to cultivate the spawn. Current technology involves directly pouring the spawn into the fermentation tank, but this method has the following problems: 1. If the poured spawn clumps, it affects cultivation within the fermentation tank; 2. Direct pouring results in uneven feeding, requiring prolonged stirring to ensure optimal cultivation, thus reducing efficiency. Therefore, there is room for improvement. Utility Model Content
[0004] This invention provides a liquid spawn fermentation tank for oyster mushrooms to solve the problems mentioned in the background art.
[0005] To address the aforementioned issues, this invention provides a liquid spawn fermentation tank for *Pleurotus ostreatus*, comprising a fermentation tank body. A feeding box is located at the top of the fermentation tank body, and an inlet communicating with the feeding box is installed at the top of the fermentation tank body. A filter screen is located in the middle of the feeding box, and the upper part of the feeding box is designated as a crushing chamber, and the lower part as a discharging chamber, through the filter screen. A discharging screen is located at the bottom of the feeding box, and the discharging screen communicates with the discharging chamber. A stirring shaft rotates within the fermentation tank, and several stirring blades are equidistantly arranged below the feeding box on the stirring shaft. The top of the stirring shaft passes through the axis of the feeding box to the top of the fermentation tank body. A stirring motor connected to the top of the stirring shaft is located at the top of the fermentation tank body. A material-dispensing plate is installed on the part of the stirring shaft located in the discharging chamber, and several stirring rods are equidistantly installed on the part of the stirring shaft located in the crushing chamber.
[0006] Preferably, a sealing plug is connected to the feed inlet at the top of the fermenter body.
[0007] Preferably, the diameter of the mesh openings in the filter screen plate inside the feeding box is smaller than the diameter of the mesh openings in the discharging screen plate.
[0008] The beneficial effects of adopting the above technical solutions are:
[0009] The inoculum is poured into the crushing chamber of the feeding box through the inlet. The rotation of the stirring motor causes the stirring rod to rotate in the crushing chamber to stir the clumps of inoculum, allowing it to fall into the feeding chamber through the mesh of the filter plate. As the stirring shaft rotates, it drives the feeding plate to rotate, allowing the inoculum to fall evenly into the fermentation tank body through the mesh of the feeding plate. The even entry of the inoculum reduces the time required for stirring and improves work efficiency. Attached Figure Description

[0014] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] like Figure 1-3 In this embodiment, a liquid spawn fermentation tank for *Pleurotus ostreatus* includes a fermentation tank body 1. A feeding box 2 is located at the top of the fermentation tank body 1, and an inlet 11 communicating with the feeding box 2 is installed at the top of the fermentation tank body 1. A filter screen 21 is located in the middle of the feeding box 2, and the upper part of the feeding box 2 is configured as a crushing chamber 3, and the lower part as a discharging chamber 4, through the filter screen 21. A discharging screen 22 is located at the bottom of the feeding box 2, and the discharging screen 22 is communicating with the fermentation tank body 1. A stirring shaft 5 is rotatably mounted inside the fermentation tank 1, and several stirring blades 51 are equidistantly arranged below the feeding box 2 in the stirring shaft 5. The top of the stirring shaft 5 penetrates through the axis of the feeding box 2 to the top of the fermentation tank body 1. A stirring motor 52 connected to the top of the stirring shaft 5 is located at the top of the fermentation tank body 1. A feeding plate 53 is installed at the part of the stirring shaft 5 located in the discharging chamber 4, and several stirring rods 54 are equidistantly installed at the part of the stirring shaft 5 located in the crushing chamber 3.
[0018] With the above technical solution, during use, the inoculum is poured into the feeding box 2 through the inlet 11. After the inoculum enters the crushing chamber 3 of the feeding box 2, the un-clumped inoculum falls into the discharge chamber 4 through the filter screen 21. At the same time, the stirring motor 52 drives the stirring rod 54 to rotate through the stirring shaft 5, stirring the clumped inoculum in the crushing chamber 3 and breaking up the clumped inoculum. The broken inoculum falls into the discharge chamber 4. Simultaneously, the stirring shaft 5 rotates the feeding plate 53 in the discharge chamber 4, and then the discharge screen 22 evenly pours the inoculum into the fermentation tank body 1. The stirring blade 51 follows the rotation of the stirring shaft 5 to evenly stir the inoculum. By ensuring the evenness of the discharge and breaking up the clumps, the clumps are prevented from directly entering the fermentation tank body 1, thereby reducing the stirring time and improving the working efficiency.
[0019] Preferably, a sealing plug 12 is provided in the feed inlet 11 at the top of the fermenter body 1.
[0020] Through the above technical solution, the sealing plug 12 in the feed inlet 11 is used to ensure the sealing of the fermenter body 1 and the stability of fermentation cultivation.
[0021] Preferably, the mesh diameter of the filter screen plate 21 inside the feeding box 2 is smaller than the mesh diameter of the unloading screen plate 22.
[0022] Through the above technical solution, the small mesh diameter of the filter screen plate 21 can prevent clumps from falling into the feeding chamber 4, and the larger mesh of the feeding screen plate 22 can facilitate the rapid and uniform introduction of bacteria into the fermentation tank body 1 in conjunction with the feeding plate 53.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
