Description

Technical Field

[0001] The utility model belongs to the technical field of mature vinegar manufacturing, and particularly relates to a vinegar vat mash turning machine. Background Art

[0002] To maintain the original flavor characteristics of vinegar, many vinegar manufacturers still use traditional vinegar vats for solid-state fermentation. During the solid-state fermentation process, particularly during the acetic acid fermentation stage, the mash must be regularly turned over to allow it to come into contact with air and ensure smooth fermentation. Traditionally, this step was performed manually, with workers using shovels to move the mash into empty vats. However, with the continuous expansion of production scale, manual turning has become insufficient to meet production needs, limiting product output and associated disadvantages such as low efficiency, high labor intensity, and long processing time. Existing turning techniques employ stirring devices, inserting a stirring rod deep into the vat to stir the mash evenly. However, this does not address the problem of turning over in some traditional processes.

[0003] Chinese patent publication number CN113980773A discloses an intelligent vinegar vat turner. Racks corresponding to the vinegar vats are fixed to the side walls of the frame. The vinegar vats are slidably connected to the frame. The machine turns the vats over as they rise, thereby achieving inverted vats. However, while this technology has made some progress in addressing the inverted vat problem, its relatively complex structure and large size make it unsuitable for some small vinegar manufacturers. Furthermore, due to its specific requirements for the shape and size of the vinegar vats, this technology is not universally applicable and is difficult to adapt to a variety of different sizes. Summary of the Invention

[0004] In order to solve the above problems, the present application provides a vinegar vat mash turning machine, which aims to move the spiral feeding device into the vinegar vat through a lifting frame, lift the vinegar mash in the vinegar vat to the discharge port, and make the vinegar mash fall into the empty vinegar vat on the other side through the material guide pipe, thereby realizing the work of turning the mash or inverting the vat.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The present application provides a vinegar vat mash turning machine, comprising a lifting device and a spiral feeding device.

[0008] The spiral feeding device includes an extraction chamber, a motor located above the extraction chamber, and a spiral blade located in the extraction chamber. The lifting frame is connected to the extraction chamber so that the extraction chamber moves up and down with the lifting frame.

[0009] The bottom end of the extraction bin is provided with a loading port, and the upper part thereof is provided with a discharging port. The motor drives the spiral blade to rotate to lift the vinegar mash from the loading port to the discharging port.

[0010] As an improvement of the above solution, the extraction bin is connected to the lifting frame through a connecting rod, and a movable groove is opened on the inner side of the frame. One end of the connecting rod passes through the movable groove and is connected to the inner side of the lifting frame, and the other end is connected to the outer wall of the extraction bin.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See Figure 1-2 , this embodiment provides a vinegar vat mash turning machine, including a lifting device and a spiral feeding device.

[0025] The lifting device comprises a frame and a lifting frame 2 installed in the frame. The lifting frame 2 uses hollow columns 1 on both sides of the frame as guide rails.

[0026] A rack 3 is provided on the outer side of the lifting frame 2, an opening 4 is opened on the frame, and a gear 5 is also installed on the frame. The gear 5 is engaged with the rack 3 through the opening 4. When the gear 5 is rotated, the lifting frame 2 moves up and down along the column 1 due to the engagement of the gear 5 and the rack 3.

[0027] The spiral feeding device includes an extraction chamber 6, a motor 7 located above the extraction chamber 6, and a spiral blade 8 located within the extraction chamber 6. A loading port 9 is defined at the bottom of the extraction chamber 6, and a discharge port is defined at the top. The spiral blade 8 is connected to the output shaft of the motor 7 via a coupling. The motor 7 drives the spiral blade 8 to rotate, lifting the vinegar mash from the loading port 9 to the discharge port.

[0028] The lifting frame 2 is connected to the extraction chamber 6, allowing the extraction chamber 6 to move up and down with the lifting frame 2. Specifically, the extraction chamber 6 is connected to the lifting frame 2 via a connecting rod 11. A movement slot (not shown) is defined on the inside of the hollow column 1. One end of the connecting rod 11 passes through the movement slot and is welded to the inside of the lifting frame 2. The other end is welded to the outer wall of the extraction chamber 6. When the lifting frame 2 moves up and down, the connecting rod 11 moves up and down within the movement slot, thereby moving the extraction chamber 6 up and down.

[0029] A return spring 12 is installed beneath the lifting frame 2, located at the bottom of the frame. When the lifting frame 2 moves downward, it compresses the return spring 12, allowing it to hover at any position. When the lifting frame 2 moves upward, the return spring 12 provides an upward force. This additional force allows the mash turner to hover at any position without worrying about the lifting frame 2 suddenly dropping, improving operational convenience and safety.

[0030] The discharge port is connected to a downwardly slanting guide pipe 10, through which the vinegar mash is moved to a new vinegar vat to achieve the work of turning the vat, or the vinegar mash is moved to the discharge port through the guide pipe 10 and then falls into the same vinegar vat A to achieve turning the mash. The guide pipe 10 can also be set as a guide plate.

[0031] A baffle 13 is connected to the outer wall of the bottom of the extraction chamber 6 via a movable pin. Baffle 13 consists of four sector-shaped plates made of a soft material. A cleaning brush 14 is attached to the outer end of each baffle 13. Each sector-shaped plate is adjusted to a fixed initial angle based on the opening size of the vinegar vat A. As the extraction chamber 6 descends, the cleaning brush 14 scrapes the remaining mash from the inner wall of the vinegar vat A into the bottom of the vat A. Due to the combined effects of gravity and the friction of the cleaning brush 14, the angle between the sector-shaped plates and the extraction chamber 6 gradually decreases during descent. Adjacent sector-shaped plates may partially overlap, allowing them to adapt to the shape of the vinegar vat A. The baffle 13 also prevents material from splashing.

[0032] The frame is equipped with a lock 15, and the bottom of the lifting frame 2 has a locking hole that matches the lock 15. When the lifting frame 2 moves upward to the position where the locking hole and the lock 15 are aligned, the spring pin of the lock 15 pops out and enters the locking hole, locking the lifting frame 2 and acting as a limiter. The lock 15 prevents the lifting frame 2 from lifting off the guide rails and causing a dangerous accident.

[0033] The bottom end of the frame is provided with a universal wheel 16 to facilitate the movement of the entire vinegar vat mash turning machine.

[0034] The working process of this embodiment is as follows:

[0035] Move the frame to the top of the vinegar vat A, turn the gear 5, and move the lifting frame 2 downward until the spiral feeding device contacts the vinegar mash. During the descent of the extraction chamber 6, the cleaning brush 14 will scrape the residual vinegar mash on the inner wall of the vinegar vat A into the bottom of the vinegar vat A. Turn on the motor 7, and the spiral blade 8 will rotate accordingly. The vinegar mash is lifted to the discharge port through the feeding port 9 and falls into the empty vinegar vat A on the other side through the guide pipe 10, completing the vat inversion work.

[0036] In addition, the vinegar mash can be moved to the discharge port through the guide pipe 10 and then dropped into the same vinegar vat A to achieve turning over. At this time, one of the sector plates can be removed to facilitate the vinegar mash to enter the vinegar vat.

[0037] When the vinegar vat mash turning machine is used in vinegar vats of different specifications, a baffle 13 of corresponding specifications can be selected according to the specifications of the vinegar vats.

[0038] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
