Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of microbial fermentation, in particular to a microbial fermentation feed production equipment. BACKGROUND

[0002] Microbial fermentation feed production is a biotechnology that improves feed quality through the metabolic activity of specific microorganisms. The core of this technology is the use of microorganisms such as lactic acid bacteria, bacillus, and yeast to biotransform agricultural and food industry by-products under controlled conditions. The production process includes raw material pretreatment, inoculation of bacterial strains, fermentation condition control, and post-processing. After the raw materials are crushed and mixed, the purified bacterial strains are inoculated. By adjusting temperature, humidity, and oxygen, the proliferation of microorganisms and the accumulation of metabolic products such as organic acids and vitamins are promoted. Finally, through drying and granulation processes, a stable product is produced. This technology significantly improves the nutritional value and palatability of feed by decomposing complex components and inhibiting harmful microorganisms.

[0003] In traditional fermentation processes, pretreated fibrous raw materials are transported to the fermentation tank and homogenized through the mechanical action of propeller blades. However, this process has the following defects: the difference in hardness between the propeller blades and the fibrous raw materials leads to non-uniform shear effects during stirring. The radial flow of the blades due to design characteristics results in strong radial fluid motion, which conflicts with the natural toughness of the fibers. When the propeller blades rotate, the friction between the blades and the material concentrates on the fiber bundles, causing mechanical shear, impact, and stretching mechanisms to damage the fiber cell wall structure, resulting in a significant reduction in effective fiber length. This physical damage not only weakens the network support function of the fibers but also directly reduces the attachment efficiency of rumen microorganisms in ruminants to fiber materials, ultimately affecting the nutritional conversion rate of the feed. Therefore, we propose a microbial fermentation feed production equipment. SUMMARY

[0039] The air jet 10 comprises a rotating shaft 101 arranged in the mounting groove 71, a circular plate 102 arranged on the rotating shaft 101, a linkage pulley 103 arranged on the rotating shaft 101 and the telescopic shaft 91, a linkage belt 104 arranged on the linkage pulley 103, a pneumatic bin 105 arranged in the mounting groove 71, a one-way air inlet valve arranged on the side wall of the pneumatic bin 105, a piston plate 106 slidably arranged in the pneumatic bin 105, a connecting rod 107 rotatably arranged on the circular plate 102, one end of the connecting rod 107 rotatably connected with the piston plate 106, a gas guide pipe arranged on the pneumatic bin 105, one end of the gas guide pipe communicated with the pneumatic bin 105 through a one-way air outlet valve, and the gas guide pipe communicated with a gas channel arranged on the mounting plate 73 and the turning and stirring rod 5.

[0040] When the telescopic shaft 91 rotates, the linkage pulley 103 is driven to rotate, and the rotating shaft 101 is driven to rotate through the linkage belt 104. The rotating shaft 101 drives the circular plate 102 arranged thereon to rotate. The circular plate 102 drives the connecting rod 107 rotatably connected therewith to drive the piston plate 106 to move circularly in the pneumatic bin 105. At this time, the gas in the pneumatic bin 105 enters the gas channel arranged on the mounting plate 73 and the turning and stirring rod 5 through the gas guide pipe, and finally is sprayed into the fermentation material through the air jet hole 51 of the turning and stirring rod 5.

The air jet hole 51 directly injects the gas into the interior of the fermentation material, thereby enhancing the oxygen transmission efficiency and the discharge capacity of metabolic waste (such as carbon dioxide) through air flow disturbance, forming a gas-solid synergistic effect with mechanical turning and stirring, further breaking the local caking phenomenon of the material, and promoting the homogenization of the distribution of the microbial population. The overall design eliminates the operation demand of manual tank opening and air supplement, fundamentally eliminates the invasion of external miscellaneous bacteria and the fluctuation of environmental parameters, stably maintains the metabolic activity of the target microorganism and the controllability of the fermentation process, and finally realizes the synchronous improvement of the fermentation efficiency and the product quality.

[0042] The mildew separation unit 11 comprises a pushing member 12 arranged on the processing bin 1, which is used to push the fermentation bin 3 to move in the processing bin 1, and the processing bin 1 is provided with a separation member 13, which is used to separate the mildew part of the raw material.

[0043] The pushing member 12 comprises a pushing bin 121 arranged on the processing bin 1, and a plurality of pushing lead screws 122 are arranged in the processing bin 1, one end of the pushing lead screw 122 penetrates the fermentation bin 3 and the processing bin 1, the other end of the pushing lead screw 122 extends into the pushing bin 121, the pushing lead screw 122 is rotationally connected with the processing bin 1 and the pushing bin 121, the pushing lead screw 122 is threadedly connected with the fermentation bin 3, and the pushing lead screw 122 is provided with a pushing belt pulley 123 at one end in the pushing bin 121, and the pushing belt pulley 123 is provided with a pushing belt 124.

[0044] The separation member 13 comprises an electric sliding table 131 slidingly arranged in the processing bin 1, the electric sliding table 131 is provided with a second electric push rod 132, the second electric push rod 132 is provided with a suction bin 133 at the tail end, the suction bin 133 is provided with a negative pressure pipe 134, the negative pressure pipe 134 is a hose, and the processing bin 1 is provided with a collection bin 135 outside, and the collection bin 135 is in communication with the negative pressure pipe 134.

[0045] When the staff checks the fermentation state, the pushing lead screw 122 is first rotated to drive the single pushing lead screw 122 to rotate, when the single pushing lead screw 122 rotates, a plurality of pushing lead screws 122 are driven to rotate synchronously through the pushing belt pulley 123 and the pushing belt 124, so as to push the fermentation bin 3 to move, so that the fermentation bin 3 is opened from the sealed state of the sealing plate 4, and the bin door 2 is provided with an observation window, through which the fermentation state of the fermentation raw material can be checked.

[0046] When the fermentation state is detected to be abnormal, the staff can control the electric sliding table 131 and the second electric push rod 132 to move the suction bin 133 to the abnormal point to suck out the fermentation raw material that produces the abnormality through negative pressure, and detect the suctioned raw material, so as to judge whether the fermentation raw material needs to be discarded according to the abnormal state, not only that, but also the gas in the processing bin 1 can be sucked out through negative pressure for treatment after the mildew is found, so as to avoid the spores of the mildew to spread and affect other normal fermentation raw materials.

[0047] The efficiency and non-invasiveness of fermentation state inspection are realized through the design of the push-out lead screw 122 and the observation window. The push-out lead screw 122 is driven by a belt and pulley transmission to realize multi-axis synchronous driving, thereby ensuring the coordination and consistency of the opening operation of the fermentation bin 3 and avoiding the risk of sealing failure caused by single-bin operation. The observation window allows the staff to directly observe the material state without opening the bin, thereby fundamentally eliminating the invasion of external miscellaneous bacteria and environmental parameter disturbance and maintaining the closedness and stability of the fermentation process.

[0048] When an abnormality is detected, the positioning system composed of the electric sliding table 131 and the second electric push rod 132 can accurately drive the suction bin 133 to move to the abnormal point, and the abnormal raw material is sucked out through negative pressure, thereby realizing rapid response to local problems and avoiding economic loss caused by the scrapping of the whole batch of materials. The negative pressure suction function is also applicable to gas treatment, can effectively capture spores generated by mold growth, prevent the spores from spreading to other normal fermentation bins 3, and block the cross-contamination path. Separate detection of the sucked raw material further enhances the accuracy of abnormality cause analysis and provides a direct basis for waste judgment, thereby realizing controllability of the fermentation process and improvement of product qualification rate.

When the fermentation bin 3 is reset, the inflatable air bag 14 is in contact with the side wall of the processing bin 1 and is extruded, so that the sealing air bag 17 is inflated and precisely adheres to the sealing plate 4, further improving the sealing performance of the fermentation bin 3 during fermentation.

[0050] Through the linkage design of the inflatable air bag 14 and the sealing air bag 17, the sealing performance of the fermentation bin 3 and the sealing plate 4 is improved. When the fermentation bin 3 is reset, the inflatable air bag 14 is deformed by being extruded by the side wall of the processing bin 1, the internal gas is transferred to the sealing air bag 17 through the air duct, the sealing air bag 17 is inflated and tightly adheres to the sealing plate 4, and the gap risk that may exist in the static sealing is effectively eliminated. The configuration of the reset spring 15 and the reset plate 16 ensures that the inflatable air bag 14 quickly returns to its original state in a non-extrusion state, thereby maintaining the long-term elasticity and sealing reliability of the air bag structure. The flexible inflation property of the sealing air bag 17 can adapt to the slight deformation or processing error of the surface of the sealing plate 4, realize full coverage sealing of the contact surface, and fundamentally block the invasion path of external miscellaneous bacteria and the disordered diffusion of internal gas. The overall design replaces the traditional rigid sealing element with a mechanical structure, thereby reducing the sealing failure probability and avoiding environmental parameter fluctuations caused by poor sealing, stably maintaining the ecological dominance of the target microorganism in the fermentation bin 3, and finally realizing the synchronous improvement of the controllability of the fermentation process and the safety of the product.
