Description

Technical Field

[0001] The utility model relates to the technical field of greengage lactic acid processing, and more specifically, to greengage lactic acid micro-fermentation equipment. Background Art

[0002] In existing technologies, the green plum lactic acid micro-fermentation process faces serious uniformity issues. The fermentation raw materials cannot be fully mixed, which may lead to uneven fermentation and local over-fermentation or under-fermentation. This will directly affect product quality and cause inconsistent taste and flavor. At the same time, static fermentation will also reduce fermentation efficiency and prolong fermentation time. Lack of mixing may also lead to uneven temperature distribution, affecting temperature control during the fermentation process.

[0003] The addition accuracy of raw materials and auxiliary materials during the fermentation process cannot be precisely adjusted, which may lead to an imbalance in the formula ratio, directly affecting the fermentation effect and the quality of the final product. Manual addition of raw materials is not only inefficient, but also prone to human errors, and it is difficult to ensure consistency between batches. In complex fermentation processes that require the addition of different raw materials in stages, the inability to perform precision adjustment will greatly increase the difficulty of operation, which may lead to inadequate process execution and affect the stability of product quality.

The auxiliary mechanism converts the rotation of the control sleeve 23 into the precise rotation of the adjustment sleeve 12 through the combination of the control sleeve 23, the inner gear ring 24, the support rod 25, the outer gear ring 26 and the gear 27. The large rotation of the control sleeve 23 can be converted into a small rotation of the adjustment sleeve 12, thereby realizing fine control of the addition amount. The setting of multiple groups of support rods 25 and gears 27 increases the stability and carrying capacity of the transmission.

[0037] In this embodiment, the fermentation raw materials are loaded into the fermentation barrel 7, and the required auxiliary materials or strains are accurately added using the control mechanism. When the control sleeve 23 rotates, the inner gear ring 24 at the bottom drives the gears 27 on the multiple groups of support rods 25 to rotate. These gears 27 are simultaneously engaged with the outer gear ring 26 on the outer wall of the adjustment sleeve 12, thereby converting the rotational motion of the control sleeve 23 into the rotational motion of the adjustment sleeve 12.

When the adjustment sleeve 12 rotates, the sealing rod 15 moves up and down in the flow tube 10 through the cooperation of the connecting sleeve 13 and the screw 14. The movement of the sealing rod 15 can change the opening degree of the multiple groups of through holes 11 on the flow tube 10. The degree of rotation of the rotating rod 2 is controlled by the mixing mechanism, thereby accurately controlling the amount of raw materials entering the fermentation barrel 7 from the input pipe 8. The strip groove 19 on the outer wall of the sealing rod 15 cooperates with the limiting strip 20 on the inner wall of the flow pipe 10 to ensure that the movement of the sealing rod 15 is stable and accurate. The setting of the connecting pipe 21 may be used to connect to an external raw material supply system. The mixing mechanism drives the transmission wheel 17 and the transmission chain 18 through the motor 16 to drive the two sets of rotating rods 2 to rotate. The supporting wheels 3 at both ends of the rotating rod 2 drive the wheel frame 4 and the fixed frame 5 to rotate together, thereby causing the fermentation barrel 7 installed between the shaft seats 6 to flip. This flipping movement can ensure that the raw materials in the fermentation barrel 7 are fully mixed, thereby improving the fermentation efficiency and uniformity.

[0042] The limit assembly is used to ensure the precise positioning of the control sleeve 23. The annular groove 28 in the control sleeve 23 and multiple sets of slidingly installed limit blocks 29 constitute a locking mechanism. When the control sleeve 23 is rotated to a specific position, the limit block 29 can slide into the limit groove 30 on the outer wall of the control sleeve 23 under the action of the push spring 31, thereby locking the position of the control sleeve 23. This design can prevent the control sleeve 23 from rotating accidentally and ensure the accuracy and stability of the adjustment.
