Description

Technical Field

[0001] The utility model relates to the technical field of brewing equipment, in particular to a mash turning device for brewing vinegar. Background Art

[0002] The process of solid-state fermentation vinegar production is to crush the grains, steam them, and then spread them out to cool them down, then mix the crushed Daqu in proportion, put them into a vat, add water for liquid fermentation to form a wine mash, pour the wine mash into the auxiliary materials made of rice bran and bran, mix them evenly, and then put them into the vat for solid-state aerobic fermentation. The auxiliary materials are used to help ventilation, and finally the alcohol is converted into acetic acid. Acetic acid fermentation is the most laborious part of the vinegar production process. During the fermentation process, the vinegar mash needs to be turned over every day. Through manual turning, hugging, holding, and rubbing, the vinegar mash in the vat is fully exposed to oxygen, which is conducive to increasing the oxygen concentration and the diffusion of nutrients. Secondly, the vinegar mash with a higher temperature at the bottom of the vat is stirred and mixed with the vinegar mash on the surface by turning the mash, so that the fermentation temperature is within a suitable range. At the same time, the vinegar mash can be ground to avoid the formation of miscellaneous bacteria after the vinegar mash agglomerates and cause bad mash.

[0003] The process of turning the mash is time-consuming, laborious, and acetic acid is irritating. At present, there are also devices that use mechanical equipment to assist in turning the mash, such as a mash turning device for vinegar brewing disclosed in Chinese Patent No.: ZL202221965871.3, which includes a support plate, a vertical track plate is arranged at the top of the support plate, a servo motor is arranged at the top of the vertical track plate, a ball screw is connected to the bottom end of the servo motor, one side of the ball screw is rotatably connected to one side of the vertical track plate, and a universal wheel is arranged at the bottom end of the support plate. By arranging the vertical track plate, the hollow column, the drive motor, the turning rod and the annular knife plate, the ball screw rotates in the opposite direction so that the ball moving block drives the turning rod on one side to insert downward into the fermentation tank, and the drive motor starts to drive the turning rod to rotate, so that the annular knife plate turns the raw materials in the fermentation box. After turning, the annular knife plate and the turning rod are lifted, and the support plate is transferred to the next fermentation tank for turning by moving the universal wheel, thereby improving the efficiency of the operation. However, the fermentation process of grain vinegar usually takes about seven to twenty days. In the early stage of fermentation, the solid mash is relatively hard and needs to be turned over every day. The efficiency of turning the mash vat by vat is low, and the mash adhering to the surface of the annular blade may fall off during the movement, affecting the factory environment. Secondly, the amount of mash produced in the early stage of fermentation is small and the mash is relatively hard. The setting of the annular blade makes it easy for the mash to rotate with the turning rod, resulting in low turning efficiency and not easy to grind the agglomerated vinegar mash. Finally, the efficiency of turning the mash vat by vat is still low. During the turning process, the turning device needs to be moved manually one by one to the top of the fermentation box where the turning operation is required. Continuous manual supervision and transportation result in a time-consuming process. Summary of the invention

[0004] The technical problem to be solved by the utility model is how to improve the efficiency of stirring the mash and how to grind the agglomerated vinegar mash during the stirring process. The purpose of the utility model is to provide a mash turning device which is suitable for a square mash tank, has high stirring efficiency, uniform stirring and low installation cost, and can effectively grind the agglomerated vinegar mash.

[0053] Embodiment 2

[0054] When using the utility model, the two tracks 11 are fixedly installed on the top of the two long sides of the rectangular mash pit, and the length of the transmission rod 112 is set according to the width of the mash pit, so that the two track wheels 111 on the same transmission rod 112 fall on the upper surface of the tracks 11 on both sides respectively, and the travel motor 13 on the bracket 12 is connected to the idler wheel 133 on the transmission rod 112 through the sprocket 131 and the chain 132, the lifting mechanism 2 is set in the bracket 12 and the rollers 212 at the front and rear ends of the lifting mechanism 2 are respectively set in the guide grooves 141 on the support rod 14, and then one end of the traction rope 154 on the winding wheel 152 at the top of the bracket 12 passes through the pulley 153 and is connected to the lifting ring 211 at the top of the lifting mechanism 2.

[0055] When in use, the support 12 is moved as a whole to the end of one end of the rectangular fermented grains tank by the travel motor 13, preferably to the end of one end of the fermented grains tank after the lifting mechanism 2 is lowered. When it is necessary to control the fermentation temperature and increase the oxygen concentration in the fermented grains according to the temperature and fermentation degree during the fermentation process, the lifting motor 151 is first started. After the lifting motor 151 rotates and releases the winding wheel 152, the lifting mechanism 2 descends under the action of gravity and slowly descends at a uniform speed under the rotation control of the lifting motor 151. The stirring mechanism 3 can be lowered to different heights according to the requirements of the fermentation process so as to turn the fermented grains at different depths. When the stirring mechanism 3 of the lifting mechanism 2 is lowered to a suitable depth along with the lifting mechanism 2, the lifting motor 151 is turned off, and the lifting mechanism 2 maintains a constant height under the pulling action of the traction rope 154, and then the stirring motor 22 in the lifting mechanism 2 is started, and the stirring motor 22 drives the stirring mechanism 3 connected to the prefabricated shaft to rotate and start stirring the mash. The stirring action of the stirring mechanism 3 causes the mash at the bottom to move up and the mash at the top to move down, thereby reducing the temperature of the mash at the bottom. At the same time, the mash is fully exposed to oxygen through continuous stirring, which helps to control the fermentation environment according to the fermentation process; the efficiency of turning the mash can be improved by two spiral blades 32 symmetrically arranged about the center of the stirring rod 31, and a The stirring paddle 35 can push the mash at the same horizontal position as the stirring paddle 35 upward to the vicinity of the spiral blade 32 when the stirring mechanism 3 rotates. The mash agglomerated at the bottom is quickly crushed by the stirring of the spiral blade 32 and the mutual friction between the mash, thereby preventing the mash from agglomerating and fermenting and producing bacteria. After the stirring mechanism 3 starts to turn the mash, the travel motor 13 can be started at the same time, and the travel motor 13 drives the idler wheel 133 on the transmission rod 112 to rotate, thereby driving the bracket 12 to move along the track 11 to the other end of the mash pool as a whole, so that the stirring mechanism 3 moves with the bracket 12, and turns the mash while moving. When the bracket 12 moves from one end of the mash pool to the other end, the turning of all mash at the same depth in the mash pool can be completed. The next time the mash is turned over, the travel motor 13 can be used to move the bracket 12 back from the other end to turn the mash again, and this process can be repeated. The turning over of the mash saves time and effort, and does not require continuous manual supervision, thereby improving the efficiency of turning the mash. The output can be expanded by increasing the length or number of mash pools, and the increased output does not affect the efficiency of turning the mash using the device.
