Description

Technical Field

[0001] The utility model relates to the field of fermentation devices, and more specifically to a microbial fermentation device. Background Art

[0002] Cultivating microorganisms generally requires a fermentation device. For example, edible fungi are cultivated in a fermentation tank. When cultivating edible fungi, some aerobic bacteria need to introduce air into the fermentation tank while stirring the nutrients to ensure sufficient production of target bacteria. In the prior art, when air is introduced into the fermentation tank, air can only enter the tank through a single air supply hole, making it difficult for the nutrients in the tank to fully contact with the air, thereby reducing the formation efficiency of the target bacteria.

[0019] The following combination Figure 1-5 To explain:

[0020] A microbial fermentation device includes a barrel 1, a cover plate 5 is fixed to the upper end of the barrel 1, a slide frame 11 slides through the cover plate 5, a partition 10 is fixed to the lower end of the slide frame 11, a plurality of air holes 13 are evenly arranged on the partition 10, and a one-way valve is provided at each of the plurality of air holes 13. An air supply pipe 4 is provided at the lower end of the barrel 1, and a one-way valve is also provided on the air supply pipe 4.

[0021] When in use, nutrients mixed with microorganisms are added into the box barrel 1 and isolated thereon by the partition 10. At the same time, the partition 10 is driven to rise and fall back in the box barrel 1 by the sliding rod frame 11. When the partition 10 moves upward, the space between the partition 10 and the bottom plate of the lower end of the box barrel 1 increases, and at the same time, the air pressure in the space is reduced, thereby opening the one-way valve on the air supply pipe 4, and air enters the space between the partition 10 and the bottom plate of the lower end of the box barrel 1 from the air supply pipe 4; when the partition 10 moves downward, the space between the partition 10 and the bottom plate of the lower end of the box barrel 1 decreases, and at the same time, the air pressure in the space is increased, thereby opening the one-way valve at the air hole 13, and air passes through the nutrients at the upper end of the partition 10 through the multiple air holes 13; thus, the partition 10 is lifted and lowered back and forth, so that the multiple air holes 13 are intermittently blown into the nutrients, and at the same time, the multiple air holes 13 are evenly distributed on the partition 10, so that air is evenly entered into the nutrients, so that the sample in the tank is fully in contact with the air;

[0022] At the same time, the reciprocating movement of the partition 10 and the blowing of air through the multiple air holes 13 at the bottom of the nutrient material can form agitation of the nutrient material, further allowing the sample in the tank to fully contact with the air;

[0023] Among them, a pressure relief valve is provided on the cover plate 5 to ensure the stability of the air pressure in the box barrel 1.

[0024] Further:

[0025] A spring is provided between the partition 10 and the bottom plate of the barrel 1 .

[0026] By setting the spring, the gravity of the nutrients on the partition 10 can be offset, thereby improving the smoothness of the reciprocating rise and fall of the partition 10.

[0027] Further:

[0028] An eccentric wheel 12 is rotated on the cover plate 5 , and the slide rod frame 11 presses the eccentric wheel 12 upward.

[0029] The eccentric wheel 12 is driven by the first motor installed on the cover plate 5, so that the eccentric wheel 12 rotates eccentrically, thereby cooperating with the spring to press the partition 10 upward, forming a reciprocating squeezing of the slide rod frame 11, and then forming a reciprocating lifting movement of the slide rod frame 11 and the partition 10.

[0030] like Figure 4-5 As shown:

[0031] A central tube 7 is rotated in the middle of the cover plate 5 , and a plurality of stirring plates 8 are fixed on the central tube 7 .

[0032] The central tube 7 is driven by a second motor installed on the cover plate 5, so that the central tube 7 drives the multiple stirring plates 8 to stir the nutrients, further allowing the sample in the tank to fully contact with the air.

[0033] like Figure 3-5 As shown:

[0034] The lower end of the central tube 7 passes through the partition 10 , and a plurality of connecting holes 9 are provided on the central tube 7 . A discharge pipe 2 slides through the center of the bottom plate of the barrel 1 , and the upper end of the discharge pipe 2 slides in the central tube 7 .

[0035] An adjusting screw 3 is rotated on the bottom plate of the box barrel 1, and the adjusting screw 3 is threadedly connected to the support arm plate fixed on the discharge pipe 2.

[0036] During fermentation, the upper end of the discharge pipe 2 is located in the central tube 7, and the multiple connecting holes 9 are blocked at the same time to prevent nutrient leakage. After the fermentation is completed, the adjusting screw 3 is rotated, and the adjusting screw 3 threadably drives the support arm plate, so that the support arm plate drives the discharge pipe 2 to descend, thereby opening the multiple connecting holes 9, and then the barrel 1 is connected to the discharge pipe 2 through the connecting holes 9 to complete the discharge.

[0037] Further:

[0038] The cover plate 5 is fixed with an adding pipe 6 for adding nutrients into the tank 1;

[0039] A valve is provided on the addition pipe 6 to close the addition pipe 6 .

[0040] Two leg plates are fixed to the lower end of the box barrel 1 to support the box barrel 1.
