Description

Technical Field

[0001] The utility model relates to the field of edible fungus production equipment, in particular to an edible fungus culture medium and fungus strain mixing device. Background Art

[0002] There are mainly two ways to prepare edible fungus culture medium. One is to put the unsterilized base material into a bag, then sterilize it at high temperature, and finally inject the bacteria to make a culture medium. The other is to mix the sterilized base material and the bacteria, and then put it into a bag to obtain a culture medium. This method can save the later sterilization step and can improve production efficiency to a certain extent.

[0003] In the related art, the sterilized base material and the bacterial strain are mixed mainly through a modified screw conveyor, that is, a channel for injecting the bacterial strain is set inside the screw conveyor, so that the bacterial strain can enter the bag at the same time as the base material outside the base material to achieve the mixing effect. The defects and shortcomings of this method are:

[0004] The bacteria injection channel is set outside the discharge barrel of the screw conveyor. When bagging, the bacteria are mainly distributed on the periphery of the base material, resulting in less bacteria in the middle of the base material and poor mixing uniformity.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] The existing mixing device of base material and strains sets the injection channel outside the discharge barrel of the screw conveyor, so that the strains are mainly distributed around the base material, resulting in less strains in the middle of the base material and poor mixing uniformity.

[0031] In order to solve the above technical problems, this embodiment provides a device for mixing edible fungus culture medium and fungus strains, please refer to Figures 1 to 3 As shown, Figure 1 It is a stereoscopic diagram of the edible fungus culture medium and strain mixing device in the embodiment, Figure 2This is a front view of the edible fungus culture medium and strain mixing device in the embodiment, Figure 3 for Figure 2 A sectional perspective view of section A.

[0032] The edible fungus culture medium and fungus strain mixing device of this embodiment includes: a hopper 1, a stirring mechanism 2 and a discharging mechanism 3.

[0033] The hopper 1 has a feed port 11, a discharge port 12 and a bacteria injection hole 13. The feed port 11 is used to input the sterilized base material. The bacteria injection hole 13 is used to inject bacteria and is located between the feed port 11 and the discharge port 12. There are a plurality of bacteria injection holes 13, which are arranged at intervals in the horizontal direction.

[0034] The stirring mechanism 2 includes a stirring shaft 21 and a stirring driving mechanism 22. The stirring shaft 21 is rotatably arranged on the hopper 1 and is parallel to the arrangement direction of the injection holes 13. The stirring shaft 21 is provided with a stirring rod 23 located in the hopper 1. The stirring driving mechanism 22 is used to drive the stirring shaft 21 to rotate so as to mix the bacteria and the base material.

[0035] The discharging mechanism 3 includes a discharging barrel 31, a discharging shaft 32 and a discharging driving mechanism 33. The discharging barrel 31 is connected to the hopper 1 and communicates with the discharging port 12. The discharging shaft 32 is arranged inside the discharging barrel 31 and the hopper 1, and is provided with a spiral blade 34 on the periphery. The discharging driving mechanism 33 is used to drive the discharging shaft 32 to rotate so that the spiral blade 34 squeezes the mixed strain and base material out of the discharging barrel 31.

[0036] When the edible fungus culture medium material and strain mixing device of the above technical scheme is working, the sterilized base material is transported to the hopper 1 from the feed port 11, and the strain is injected into the hopper 1 from the injection hole 13, and the stirring mechanism 2 then drives the stirring shaft 21 to rotate through the stirring drive mechanism 22 to mix the strain and the base material, and finally, the discharging mechanism 3 drives the discharging shaft 32 to rotate through the discharging drive mechanism 33, so that the spiral blade 34 squeezes the mixed strain and base material from the discharging barrel 31 and puts them into the bag to obtain the culture medium; wherein, the arrangement direction of the injection hole 13 is parallel to the stirring shaft 21, and the strain is injected into the hopper 1 through the injection hole 13 in a direction parallel to the stirring shaft 21, and combined with the uniform stirring of the stirring mechanism 2, the distribution and stirring of the strain and the base material are more uniform and sufficient, which is beneficial to further improve the quality of the obtained culture medium and is beneficial to the growth of mushrooms in the later stage.

[0037] Exemplarily, the injection holes 13 are arranged at equal intervals, which is beneficial to further improve the uniformity of the distribution of the bacteria and the mixing with the base material.

[0038] Exemplarily, the injection hole 13 is connected to an existing injection device for injecting bacterial strains through a pipeline, and the injection device injects bacterial strains into the injection hole 13 through the pipeline.

[0039] In an embodiment in which the stirring shaft 21 is arranged in parallel with the injection holes 13, the hopper 1 is provided with a stirring chamber 14, the cross-section of the chamber wall of the stirring chamber 14 is square, the injection holes 13 are arranged along the length direction of a chamber wall of the stirring chamber 14, and the stirring shaft 21 is rotatably connected to the other two adjacent chamber walls.

[0040] Exemplarily, the stirring shaft 21 is rotatably connected to the wall via a bearing.

[0041] In order to facilitate the input of the base material into the hopper 1 from the feed port 11, the mixing device also includes a transfer bucket 15, which is connected to the hopper 1 and communicates with the feed port 11, and is used to connect a conveying mechanism for the base material. In this way, the conveying mechanism can convey the base material after high-temperature sterilization to the hopper 1 through the transfer bucket 15, thereby realizing automatic loading.

[0042] In order to facilitate the cleaning of the discharge mechanism 3 and the hopper 1, the hopper 1 is provided with an opening and a door panel 16 for sealing the opening. One end of the door panel 16 is rotatably connected to the hopper 1, and the other end is connected to the hopper 1 by a quick release buckle 17. When cleaning, the door panel 16 can be quickly opened by the quick release buckle 17, and the cleaning water can enter or flow out from the opening to achieve cleaning of the discharge mechanism 3 and the hopper 1.

[0043] Exemplarily, the door panel 16 is made of a transparent material, so that the door panel 16 can also serve as an observation window, making it convenient for operators to understand the situation in the hopper 1 through the door panel 16 .

[0044] In one embodiment in which the above-mentioned discharge shaft 32 outputs the mixed material through the spiral blade 34, the discharge shaft 32 is located below the stirring shaft 21 and at the bottom end of the hopper 1. The mixed bacteria and base material fall into the bottom end of the hopper 1 by their own weight and are transported to the discharge barrel 31 by the spiral blade 34 and finally output from the discharge barrel 31.

[0045] In order to further optimize the uniformity of the distribution of the strain in the hopper, an injection channel 201 is provided inside the stirring shaft 21. One end of the injection channel 201 is connected to the outside of the stirring shaft 21, and is connected to one end of the conveying pipeline through a high-precision rotary joint 203 to avoid interfering with the rotation of the stirring shaft 21. The other end of the pipeline is directly connected to the injection equipment. At the same time, the stirring rod 23 is provided with a number of injection holes 202 that are connected to the injection channel 201. In the actual working process, the injection equipment accurately injects the strain into the injection channel 201 of the stirring shaft 21 through the pipeline. As the stirring shaft 21 rotates, the strain is evenly sprayed into the base material in the hopper through the injection holes 202. This design not only ensures the full mixing of the strain and the base material, but also significantly improves the uniformity of the strain distribution, thereby optimizing the quality and performance of the final product.

[0046] In one embodiment of the stirring drive mechanism 22 and the discharging drive mechanism 33 , the stirring drive mechanism 22 and the discharging drive mechanism 33 are motor drive mechanisms, and are drivingly connected to the stirring shaft 21 and the discharging shaft 32 .

[0047] Exemplarily, the motor drive mechanism is connected to the stirring shaft 21 and the discharging shaft 32 via a gear transmission mechanism, a chain transmission mechanism or a belt transmission mechanism.
