DETAILED DESCRIPTION

[0049] The purpose of mixing the morel culture medium is to ensure that the components in the culture medium are fully mixed and evenly distributed, ensuring that all strains have access to the same growth environment and working nutrients. If the culture medium is not mixed evenly, the strains may grow poorly or even die. At the same time, mixing can also reduce the uneven distribution of oxygen in the culture medium, thereby improving the growth rate and production efficiency of the strains.

[0050] The composition of Morel culture medium varies depending on the species and production process, but generally includes the following:

[0051] Carbon source: usually glucose, maltose, yeast extract, etc., used to provide energy and nutrition.

[0052] Nitrogen source: usually peptone, beef extract, yeast extract, etc., used to provide nutrients such as amino acids and protein.

[0053] Inorganic salts: including potassium dihydrogen phosphate, magnesium sulfate, sodium chloride, etc., used to provide trace elements and electrolytes.

[0054] Vitamins: usually include vitamin B1, niacin, nicotinic acid, etc., which are used to promote bacterial growth.

[0055] Water: As the main component of the culture medium, it is used to provide moisture and solutes.

[0056] Agar: used as a coagulant in the culture medium to fix the bacteria.

[0057] In addition to the above ingredients, different strains may also require the addition of other ingredients, such as yeast extract, casein peptone, tryptone, etc. When selecting culture medium components, it is necessary to select and adjust according to different strains and production processes;

[0058] During the mixing process of the Morchella culture medium, if a fermentation tank is used, mechanical stirring is usually used to mix the culture medium evenly. If a blender is used, it is mixed with an electric stirrer. Regardless of the equipment used, it is necessary to ensure uniform mixing to ensure the growth and development of the fungus.

[0059] The following is specifically described by way of examples:

[0060] Example:

[0061] See Figure 1-2 This embodiment discloses a mixing device for a morel culture medium, comprising a support frame 100 and a mixing box 110, and further comprising:

[0062] Rotating shaft 130, the rotating shaft 130 is installed at an eccentric position at both ends of the mixing box 110, the rotating shaft 130 is rotatably connected to the support frame 100, and the rotating shafts 130 at both ends of the mixing box 110 are coaxial;

[0063] The central axis of the mixing box 110 is arranged to intersect with the central axis of the rotating shaft 130;

[0064] A third motor 120 is also installed at one end of the rotating shaft 130, and the mixing box 110 can be driven to rotate by the third motor 120;

[0065] A material port 140 is provided on the side wall of the mixing box 110 for filling or discharging materials;

[0066] like Figure 2 As shown, through the above scheme, when the third motor 120 drives the rotating shaft 130 and the mixing box 110 to rotate, the mixing box 110 will tilt left and right in real time, so the material inside the mixing box 110 can also slide back and forth left and right. When the mixed material slides left and right in the mixing box 110, a better stirring and mixing effect can be obtained, thereby improving the mixing efficiency.

[0067] Continue reading Figure 3As a possible embodiment, the internal shape of the mixing box 110 is a polygon, which can be a regular polygon or an irregular polygon. The polygonal stirring pool is close to a circle and has edges and corners to achieve a stirring function, so that the medium is stirred evenly;

[0068] Other benefits of using polygonal containers for mixing include:

[0069] 1. Enhanced mixing effect: Polygonal containers can make the materials more evenly distributed in the container, avoiding the concentration of materials in a certain part of the container, thereby improving the mixing effect;

[0070] 2. Increase reaction rate: Stirring materials in a polygonal container can increase the contact area between materials, thereby accelerating the chemical reaction rate;

[0071] 3. Reduce energy consumption: When stirring in a polygonal container, the material can be more evenly distributed in the container, so that a lower stirring speed can be used, reducing energy consumption;

[0072] 4. Improve product quality: Mixing materials in a polygonal container can more accurately control process parameters such as temperature and concentration, thereby improving product quality;

[0073] 5. The material is dispersed more evenly: Due to the polygonal structure, when the mixing box 110 rotates, a portion of the material will temporarily stay on one side of the polygon, and then continue to rotate the mixing box 110 to drop the material. If the mixing box 110 is circular, when the mixing box 110 rotates, the material will always be at the bottom of the mixing box 110, and the material will not be easily dispersed.

[0074] like Figure 3 As shown, a scraping mechanism is provided inside the mixing box 110, and the scraping mechanism includes:

[0075] a scraper frame 210 , wherein the shape of the scraper frame 210 matches the shape of the inner wall of the mixing box 110 , and the outer edge of the scraper frame 210 contacts the inner wall of the mixing box 110 ;

[0076] A driving member is installed between the scraper frame 210 and the inner wall of the mixing box 110, and is used to drive the scraper frame 210 along the central axis of the mixing box 110;

[0077] It should be noted that the above-mentioned driving member can be an electric telescopic rod, a pneumatic telescopic rod or a hydraulic telescopic rod, and the driving member can drive the scraper frame 210 to slide in the mixing box 110, thereby scraping off the material adhered to the inner wall of the mixing box 110, so that the inner wall of the mixing box 110 remains clean.

[0078] As a possible embodiment, the driving member may be composed of the following components:

[0079] A screw rod 230, both ends of which are rotatably connected to the inner wall of the mixing box 110 via bearings, and the screw rod 230 is threadedly connected to the scraper frame 210;

[0080] A first motor 220 is used to drive the screw rod 230 to rotate, and an output end of the first motor 220 is connected to one end of the screw rod 230 through a coupling;

[0081] The screw rod 230 is driven to rotate by the first motor 220 , and since the outer wall of the scraper frame 210 is slidably connected to the inner wall of the polygonal mixing box 110 , when the screw rod 230 rotates, the scraper frame 210 can be caused to slide inside the mixing box 110 .

[0082] Continue reading Figure 4 The inner side of the scraper frame 210 is provided with a stirring device 300, and the stirring device 300 includes:

[0083] A fixing ring 310 , the fixing ring 310 being fixedly connected to the inner side of the scraper frame 210 via a connecting rod 320 ;

[0084] A rotating ring 330 , wherein the rotating ring 330 is rotatably connected to the fixed ring 310 , and the rotating ring 330 rotates on the fixed ring 310 driven by the rotation drive device;

[0085] A stirring rod 331 , wherein the stirring rod 331 is connected to the inner side of the rotating ring 330 , and there are multiple stirring rods 331 ;

[0086] The rotating ring 330 is driven to rotate by the rotary driving device, so that the stirring rod 331 rotates synchronously, thereby achieving a stirring effect on the material and allowing the morel culture medium to be fully mixed.

[0087] The open end of the stirring rod 331 is connected to a stirring blade 332 , which is a multi-layer structure. The width of the stirring blade 332 is greater than the diameter of the stirring rod 331 ;

[0088] It should be noted that the stirring blade 332 can be made of metal material or carbon fiber material.

[0089] like Figure 4-7 As shown, a ring groove 340 is formed on the inner side of the fixed ring 310 , the rotating ring 330 is rotatably connected to the ring groove 340 , and the stirring rod 331 is rotatably connected to the inner side of the rotating ring 330 .

[0090] As a possible embodiment, the above-mentioned rotation drive device may be composed of the following components:

[0091] The second motor 370 is fixedly mounted on the scraper frame 210 and is used to drive the rotating ring 330 to rotate;

[0092] A driving gear 360 is connected to an output end of the second motor 370;

[0093] A driven gear 350 is connected to the outer side of the rotating ring 330 , and the driven gear 350 is meshed with the driving gear 360 ;

[0094] When the second motor 370 is started, the second motor 370 drives the driving gear 360 to rotate. Since the driving gear 360 is engaged with the driven gear 350, the driven gear 350 also rotates. Therefore, the rotating ring 330 integrally connected to the driven gear 350 also rotates synchronously, so that the stirring rod 331 and the stirring blade 332 inside the rotating ring 330 also rotate synchronously, achieving the effect of stirring and mixing.

[0095] As a possible embodiment, a gear ring 333 is connected to the inner side of the fixing ring 310 , and a pinion 334 is connected to the root of the stirring rod 331 , and the pinion 334 is meshed with the gear ring 333 ;

[0096] Through the above solution, when the rotating ring 330 and the fixed ring 310 rotate relative to each other, the pinion 334 meshes with the gear ring 333, thereby causing the pinion 334 to rotate.

[0097] As a possible embodiment, the output end of the second motor 370 is further connected to a soft rod 361, and the open end of the soft rod 361 is connected to a soft sheet 362. The soft sheet 362 corresponds to the position of the stirring blade 332. When the second motor 370 drives the soft rod 361 and the soft sheet 362 to rotate, the soft sheet 362 can scrape off the material adhering to the stirring blade 332.

[0098] It should be noted that the soft sheet 362 and the soft rod 361 can be plastic sheets, metal sheets, or rubber sheets.

[0099] Since the stirring blade 332 contacts the morel culture medium when rotating, part of the material will adhere to the stirring blade 332, so the stirring blade 332 needs to be cleaned. By setting a soft rod 361 and a soft film 362 at the output end of the second motor 370, and the position of the soft film 362 corresponds to the stirring blade 332, the material adhering to the stirring blade 332 can be scraped off by the soft film 362, thereby achieving a cleaning effect.

[0100] A cleaning ring 410 is further provided at one end of the scraper frame 210. The cleaning ring 410 is rotatably connected to one end of the scraper frame 210 via a bearing 440. Bristles 420 are connected around the cleaning ring 410. The ends of the bristles 420 abut against the inner wall of the mixing box 110. A cleaning gear 430 is connected to the output end of the second motor 370. Teeth are provided on the inner side of the cleaning ring 410. The cleaning gear 430 meshes with the teeth. It should be noted that the bristles 420 can be made of metal wire, plastic or rubber and have a certain toughness.

[0101] Through the above solution, when the second motor 370 drives the cleaning gear 430 to rotate, the cleaning gear 430 engages with the teeth on the inner side of the cleaning ring 410, so that the cleaning ring 410 rotates synchronously, allowing the bristles 420 to clean the inside of the mixing box 110, further improving the cleaning ability.
