Description

Technical Field

[0002] Integrated fermentation equipment utilizes an integrated design, integrating functional modules such as fermentation tanks, steam generators, and air handling components into a single system. This improves production efficiency and is suitable for small- to medium-scale production. The fermentation process for feed flavoring requires extremely high environmental cleanliness. Air, a key component of the culture medium, can contain moisture, impurities, and microorganisms that can easily contaminate the fermentation broth, reduce bacterial activity, and even affect the synthesis of flavor compounds in the flavoring. Therefore, air filtration, dehumidification, and sterilization are key components of fermentation equipment.

[0003] Existing integrated fermentation devices usually use a single filter device to remove dust and dehumidify the air. They lack deep dehumidification methods and cannot effectively remove moisture from the air, which can easily lead to condensation and accumulation of water in the fermentation tank. The sterilization device is only equipped with a small number of ultraviolet lamps, and the air flowing through is irradiated for a short time, which cannot reliably kill microorganisms in the airflow, resulting in a significantly increased risk of bacterial contamination during the fermentation process, which in turn affects the yield and quality of the flavoring agent.

When the desiccant absorbs When moisture causes weight to increase, the desiccant filling cylinder 14 applies downward pressure to the support ring 16 through the bottom cover 146, compressing the telescopic rod 15 and driving the pressure block 18 to move downward. The inclined surface on the pressure block 18 generates a horizontal component of force during contact with the contact wheel 21, pushing the sliding rod 19 to move toward the outside of the dehumidification tank 7. At this time, the second spring 23 is stretched to generate a reverse force, and the identification rod 24 moves with the connecting block 22 to the corresponding position of the reference scale 25.

When the filter cotton needs to be replaced, hold the top part of the handle 40 and press it diagonally downward to rotate the mounting ring 39 to a horizontal state, no longer forming an obstruction to the filter cotton. Then the relevant personnel can take out the filter cotton and replace it with a new one. Release the handle 40, and under the action of the torsion spring 42, the mounting ring 39 will automatically reset to a vertical state.

[0031] In this embodiment: After being extracted by the air pump 5, the outside air first enters the filter cartridge 13, and the dust particles are pre-filtered by the composite filter structure composed of primary efficiency, medium efficiency and high efficiency filter cotton. Then, the air enters the refrigerated dryer 6 through the air inlet pipe, and the refrigeration technology is used to condense and precipitate the moisture in the air, removing most of the water vapor. Then, the air enters the dehumidification tank 7 through the first exhaust pipe 9. In the desiccant filling cylinder 14, the air passes through multiple filling grids of the upper and lower filling chambers in turn, and the silica gel desiccant further absorbs the remaining moisture through the series dehumidification path; the dehumidified air enters the sterilization box 8 through the bellows 11 and the fixed pipe 10. The flow equalizing plate in the sterilization box 8 first evenly disperses the airflow, and the multiple layers of ultraviolet lamps 26 arranged longitudinally and equidistantly in the horizontal direction form a three-dimensional irradiation area to thoroughly sterilize the air. Finally, the air is introduced into the air pump 5 through the second exhaust pipe 12, and after being pressurized by the air pump 5, it is input into the air disk in the fermentation tank 2, which disperses the sterile air into tiny bubbles and efficiently dissolves them in the fermentation liquid for fermentation needs.

[0032] The observation port of the dehumidifier tank 7 is combined with the acrylic desiccant filling cylinder 14, which allows the moisture absorption status of the desiccant to be visually checked. In the displacement indication mechanism, the desiccant presses down the support ring 16 after absorbing moisture and increasing in weight. The telescopic rod 15 compresses the inclined surface of the pressure block 18 and pushes the contact wheel 21, so that the sliding rod 19 drives the marking rod 24 to move on the reference scale 25, and the degree of moisture absorption is indicated by the scale; the ultraviolet sterilization unit of the sterilization box 8 is pulled out and pulled by the sliding plate 28 in the fixed box 27. After the rotating baffle 31 is rotated upward by 90°, it will contact the magnet block 32 and be adsorbed. Then the lamp tube on the mounting plate 29 can be pulled out for cleaning. After the rotating shaft 33 and the locking piece are turned 90° for maintenance, the ultraviolet lamp tube 26 can be in a vertical state and no longer between the two sliding plates 28, which is more convenient for cleaning and maintenance; the mounting ring 39 of the filter cartridge 13 is pressed against the cartridge mouth by the torsion spring 42. Pressing the handle 40 can rotate the mounting ring 39, making it convenient to remove the filter cotton for replacement.

[0033] Second embodiment: This embodiment provides a fermentation method, comprising the following steps: T1: Check the desiccant in the integrated fermentation device for loss. Replace the desiccant when its color reaches the characteristic color corresponding to its saturated state. T2: First, add the basal culture medium and other raw materials required for fermentation except the bacterial strain into the fermentation tank 2, start the steam generator 3 to generate steam, preheat and sterilize the fermentation tank 2 and the raw materials inside to ensure that the equipment and raw materials are in a sterile environment; T3: After sterilization is completed, wait until the temperature in fermenter 2 drops to a temperature range suitable for bacterial survival, then add bacterial strains according to the formula ratio; T4: Turn on the stirring device in the fermentation tank 2 to fully stir the culture medium, bacterial strain and other raw materials to ensure full contact between the bacterial strain and the nutrients. During the stirring process, add an appropriate amount of defoaming agent through the liquid pump on the defoaming agent storage tank 4 to prevent excessive foam from affecting the fermentation effect and equipment operation during the fermentation process; T5: Start the air pump 5 and the refrigerated dryer 6 to pass the purified air into the fermentation tank 2 and dissolve it in the fermentation liquid. Monitor the fermentation parameters in real time and adjust the equipment operating parameters to control the fermentation process. T6: After fermentation is completed, the fermentation liquid is discharged and the equipment is cleaned and maintained.
