Description

Technical Field

[0001] This utility model relates to the field of fungal cultivation technology, specifically to a device for preparing edible fungal cultivation substrate. Background Technology

[0002] Golden ear fungus is a precious medicinal and edible fungus. Its spore preparation process involves pre-mixing the cultivation substrate for the golden ear fungus spores, then inoculating the substrate with the spores to cultivate the fungus. Currently, the formulation of the golden ear fungus spore cultivation substrate includes sawdust, wheat bran, corn flour, gypsum powder, sucrose, and water. During the cultivation process, the cultivation substrate usually needs to be uniformly mixed to ensure a balanced supply of nutrients and consistency in spore cultivation. Chinese patent document CN218189051U discloses a pre-mixing device for golden ear fungus spore cultivation materials. This device uses two sets of mixing rods in a dual mixing component and two sets of spiral conveyors for stirring. This increases the quantity of golden ear fungus spore materials mixed at one time and improves the uniformity of the mixture. After mixing, the spiral conveyors actively and spirally discharge the mixed materials, reducing the workload for workers. However, the mycelium of *Auricularia auricula-judae* has weak growth capacity, and the cultivation substrate (especially natural organic matter such as sawdust and wheat bran) carries a large number of miscellaneous bacteria (such as Bacillus, Penicillium, Aspergillus, and yeast). These miscellaneous bacteria grow faster than the *Auricularia auricula-judae* mycelium, leading to problems such as slow growth, thinness, or even cessation of growth during the cultivation process due to insufficient nutrients. Therefore, sterilization of the cultivation substrate is usually required during the cultivation of *Auricularia auricula-judae* spawn. Current technology typically involves sterilizing the uniformly mixed substrate after premixing. This sterilization method has two drawbacks: firstly, it cannot penetrate deep into the substrate, leaving a large number of miscellaneous bacteria inside, resulting in incomplete sterilization; secondly, it easily disperses the uniformly mixed substrate, leading to uneven mixing and the need for secondary stirring, which affects cultivation efficiency. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a device for preparing edible fungi cultivation material. This device can simultaneously sterilize the cultivation material during the mixing process, thoroughly removing miscellaneous bacteria from the cultivation material and providing a sterile, safe, and nutrient-rich growth environment for the auricularia auricula mycelium.

[0004] The objective of this utility model is achieved through the following technical solution: A device for preparing edible fungi cultivation substrate includes a crushing box and a mixing box. The crushing box is located on the top surface of the mixing box, and their sides are connected by a feeding pipe. The central axis of the mixing box is horizontal. A coaxial mixing cylinder is installed inside the mixing box, and one side of the mixing cylinder is fixedly connected to the corresponding inner wall of the mixing box. A mixing rod is coaxially installed inside the mixing cylinder, with one end of the mixing rod penetrating through the corresponding side wall of the mixing cylinder and rotatably connected to the inner wall of the mixing box. The other end of the mixing rod penetrates through the side wall of the mixing box and is connected to an external high-temperature steam device.

The cavity is connected to the airflow channel. An annular rotating cylinder is installed between the outer wall of the mixing cylinder and the inner wall of the mixing box, and ultraviolet lamp strips are evenly arranged on the inner wall of the annular rotating cylinder.

[0005] Based on further optimization of the above scheme, the bottom surface of the crushing box is fixedly connected to the top surface of the mixing box through a connecting block, and a positioning bracket is provided on the bottom surface of the mixing box.

The bottom surface of the cavity is provided with a sloping structure, and the sloping structure is in the opposite direction to the sloping direction of the filter screen; the bottom end of the sloping structure is connected to the feed pipe.

[0007] Based on further optimization of the above scheme, the pulverizing box is provided with a movable door at the inclined bottom end of the filter screen, and the movable door is located on the upper side of the end face of the filter screen.

[0008] Based on further optimization of the above scheme, the side wall of the stirring tank is made of transparent material, and the end face of the stirring tank is made of light-shielding material.

[0009] Based on further optimization of the above scheme, the mixing tank is located on the side corresponding to the feeding pipe and a vent pipe is provided on the mixing cylinder, and a one-way valve is provided on the vent pipe for the external discharge of gas in the mixing cylinder while preventing external gas from entering the mixing cylinder through the vent pipe.

[0010] Based on further optimization of the above scheme, the mixing tank is located on the side corresponding to the feeding pipe and the discharge port is set at the bottom of the mixing cylinder, and a sealing rubber plug is set at the discharge port.

[0011] Based on further optimization of the above scheme, the stirring rod and the annular rotating drum are driven by a gear mechanism. The gear mechanism includes an incomplete gear, two transmission gears, a first internal gear ring, a second internal gear ring, and two intermediate gears. The outer wall of the stirring rod between the stirring drum and the stirring box is sequentially fitted with two transmission gears along its axial direction. The first internal gear ring is coaxially arranged with the stirring rod and one side of the first internal gear ring is fixedly connected to the annular rotating drum. Two intermediate gears are symmetrically arranged between the transmission gear near the stirring drum and the first internal gear ring, and the intermediate gears mesh with the outer wall of the corresponding transmission gear and the inner wall of the first internal gear ring, respectively. The incomplete gear is rotatably arranged on the side wall of the stirring box and corresponds to the transmission gear away from the stirring drum. The incomplete gear and the outer ring of the corresponding transmission gear are provided with a second internal gear ring. The transmission gear can mesh with the inner ring of the second internal gear ring and the tooth segment of the incomplete gear.

[0012] Based on further optimization of the above scheme, the arc length of the tooth segment of the incomplete gear is less than half of its circumference.

[0013] The following are the technical effects of this utility model: This invention achieves uniform mixing of the cultivation material within the mixing drum through the cooperation of a mixing box, mixing drum, mixing rod, connecting rod, and flap, avoiding uneven mixing caused by the cultivation material settling to the bottom or adhering to the inner wall of the mixing drum. Simultaneously, high-temperature steam is continuously introduced into the mixing drum via the mixing rod and connecting rod, ensuring effective penetration of the steam into the raw materials during mixing to kill any bacteria, insect eggs, etc. Furthermore, the invention utilizes a synchronously rotating annular drum with ultraviolet lamps on its inner wall to achieve ultraviolet sterilization during mixing, which, combined with high-temperature steam sterilization, achieves complete and thorough sterilization, ensuring the aseptic nature of the cultivation material and providing a sterile, safe, and nutrient-rich growth environment for the auricularia auricula-judae mycelium.

Figure 2 As shown, the gear rotates clockwise (at this time, the smooth section of the incomplete gear 271 corresponds to the second internal gear ring 274). With the rotation of the incomplete gear 271, when the tooth segment of the incomplete gear 271 disengages from the transmission gear 272 and meshes with the second internal gear ring 274, the second internal gear ring 274 drives the transmission gear 272 and the stirring rod 22 as shown. Figure 2 It rotates counterclockwise as shown. Simultaneously, during the rotation of the stirring rod 22, it moves in a manner as shown... Figure 1 The rotating gear 272 and two intermediate gears 275 on the left drive the first internal gear ring 273 to rotate, which in turn drives the annular rotating drum 25 and the ultraviolet lamp strip 250 to circulate and rotate repeatedly around the central axis of the mixing drum 21, achieving uniform irradiation of the inner side of the mixing drum 21. Afterwards, by feeding material into the crushing box 10, the material is crushed, filtered, and guided by the crushing box 10, and then introduced into the mixing box 20 through the feeding pipe 14.
