Description

Technical Field

[0001] The present invention relates to the technical field of vinegar brewing preparation, and particularly relates to a device and method for preparing a mixed type vinegar solid starter primary product. Background Art

[0002] During the vinegar brewing process, making the vinegar solid starter is an extremely crucial process, and the fermentation degree of the vinegar solid starter directly affects the quality and taste of the later vinegar. As the core substance during the fermentation process, the fermentation degree of the vinegar solid starter has a decisive impact on the quality and taste of the final vinegar product. First of all, from a technological perspective, making the vinegar solid starter is an important bridge connecting raw material pretreatment and acetic acid fermentation. During the process of making the vinegar solid starter, after the raw materials are pretreated through crushing, mixing, steaming, etc., they are fermented together with specific microbial strains. This process not only provides a suitable environment for the growth and reproduction of microorganisms but also lays a solid foundation for subsequent acetic acid fermentation. Secondly, the fermentation degree of the vinegar solid starter is crucial for the quality of vinegar. When the fermentation degree is moderate, nutrients such as sugars and proteins in the vinegar solid starter can be fully converted, generating rich organic acids and flavor substances, thus endowing the vinegar with a unique aroma and taste. On the contrary, if the fermentation degree is insufficient or excessive, it will lead to a decline in the quality of vinegar and a poor taste. Moreover, the fermentation degree of the vinegar solid starter also directly affects the taste of vinegar. For the vinegar solid starter with moderate fermentation, the types and quantities of organic acids generated are more balanced, making the final vinegar product have a mellow taste and a long aftertaste. While for the vinegar solid starter with insufficient fermentation, the taste of the vinegar may be too thin and lack a sense of hierarchy; for the vinegar solid starter with excessive fermentation, the taste of the vinegar may be too sour and astringent to be palatable. Therefore, during the vinegar brewing process, it is necessary to strictly control the conditions of the vinegar solid starter making link, including the selection of raw materials, the use of microbial strains, fermentation temperature and time, etc., to ensure that the fermentation degree of the vinegar solid starter is moderate, so as to produce high-quality vinegar products with a unique taste.

[0003] In the traditional process of making vinegar solid starter, wheat bran is first put into the vinegar solid starter strip pool, then wine mash is sprinkled through a pipeline, and a turning machine is used to stir back and forth to mix the two. This method will cause large-area dust flying in the workshop due to the dry and light physical properties of wheat bran when it is put into the pool alone, and there is a risk of dust explosion. At the same time, it takes a long time for the wheat bran and wine mash to be evenly mixed in the vinegar solid starter pool, and it is difficult to ensure uniform mixing, which directly affects the fermentation duration and quality of the later vinegar solid starter.

[0039] Among them, the automatic unpacking machine 1 is connected to the double-station mixing machine 5 and is used to convey wheat bran into the double-station mixing machine 5. The fermented grains buffer tank 7 is connected to the double-station mixing machine 5 and is used to supply fermented grains to the double-station mixing machine 5.

[0040] Embodiment 1

[0041] As Figure 1 shown, in an embodiment of the present invention, the automatic unpacking machine 1 is connected to the wheat bran elevator 2, and the wheat bran is lifted to the wheat bran buffer bin 3 by the wheat bran elevator 2 for buffering;

[0042] The wheat bran elevator 2 lifts the wheat bran into the wheat bran buffer bin 3 through the combined action of the driving device and the traction device inside it; the wheat bran elevator 2 is an existing device, and its working principle is to vertically lift the material through a series of hoppers fixedly connected to the endless traction member. Specifically, the wheat bran elevator 2 mainly consists of hoppers, a driving device, top and bottom drums (or sprockets), a belt (or traction chain), a tensioning device, and a casing, etc. After starting the equipment, the driving device starts to operate, driving the traction member (such as a chain or a belt) to perform a circular motion. A series of hoppers are fixedly connected to these traction members, and they perform continuous lifting and lowering motions along the path of the traction member.

[0043] The working process of the wheat bran elevator 2 is as follows: The material is fed into the hopper of the wheat bran elevator 2 from the discharge port of the automatic unpacking machine 1. As the hopper rises, the material is lifted to a high place. When the hopper moves to the top, it will bypass the top wheel and then turn downward to pour the material into the receiving trough, completing the discharging process. This process is repeated continuously, thus realizing the continuous lifting and conveying of the material.

[0044] A radar level gauge 301 is provided on the wheat bran buffer bin 3 for measuring the level of wheat bran in the wheat bran buffer bin 3; a rotary feeder valve 302 is provided at the lower end of the wheat bran buffer bin 3 for evenly feeding the wheat bran into the double-station mixing machine 5 by rotation; the radar level gauge 301 is electrically connected to the wheat bran elevator 2, the automatic unpacking machine 1, and the rotary feeder valve 302, and the feeding of the wheat bran elevator 2 and the automatic unpacking machine 1 and the discharging of the rotary feeder valve 302 are controlled in reverse by the wheat bran level. A dispersing mechanism is provided in the wheat bran buffer bin 3 to prevent the wheat bran, the material, from bridging.

[0045] Its overall working process is as follows: After the automatic unpacking machine 1 unpacks the wheat bran, it is dust-removed through the pulse dust removal device, and then the wheat bran is lifted by the wheat bran elevator 2 into the wheat bran buffer bin 3 for temporary storage; the radar level gauge 301 measures the level of the wheat bran in the wheat bran buffer bin 3 and transmits information to the wheat bran elevator 2. When the wheat bran in the wheat bran buffer bin 3 reaches the set height, the radar level gauge 301 transmits a signal to stop feeding to the wheat bran elevator 2, and the wheat bran elevator 2 stops lifting the wheat bran; then the rotary feeder valve 302 is started to evenly feed the wheat bran into the double-station mixer 5 for mixing; when the height of the wheat bran in the wheat bran buffer bin 3 drops to the height required for feeding, the radar level gauge 301 transmits a signal to start feeding to the wheat bran elevator 2, and the wheat bran elevator 2 starts to lift the wheat bran, and thus the feeding and discharging of the wheat bran buffer bin 3 are carried out in a cycle.

[0046] The dust generated during the unpacking of the wheat bran is removed by the automatic unpacking machine 1, and then the wheat bran is lifted by the wheat bran elevator 2 into the wheat bran buffer bin 3 for caching, thereby avoiding the generation of dust during the mixing of the wheat bran and further polluting the environment and causing potential safety hazards.

[0047] Embodiment 2

[0048] As Figure 1 shown, in an embodiment of the present invention, a wheat bran blanking pipe 4 is provided between the wheat bran buffer bin 3 and the double-station mixer 5.

[0049] The wheat bran in the wheat bran buffer bin 3 enters the wheat bran blanking pipe 4 through the rotary feeder valve 302. The wheat bran stops when it falls to the position where the wheat bran feed valve 401 is located by gravity in the wheat bran blanking pipe 4. When there is too much wheat bran in the wheat bran blanking pipe 4, the wheat bran will block the rotation of the rotary feeder valve 302, thus stopping the discharging; when it is necessary for the wheat bran to enter the double-station mixer 5, the wheat bran feed valve 401 is opened, and the wheat bran enters the tank body 6 of the double-station mixer 5 and waits to be mixed with the fermented mash. The rotary feeder valve 302 can make the discharging smoother and more uniform, avoiding congestion at the discharging place.

[0054] The mash is input into the double-station mixer 5 through the mash buffer tank 7, and the flow rate of the mash is controlled by using the mash flowmeter 705, the mash valve 703 and the mash conveying pump 704, so that the mixing is carried out in a certain proportion, and the automatic feeding of the mash can be realized, and the uniformity of the mixing can be improved.

The dust-removed wheat bran is lifted to the wheat bran buffer bin 3 by the wheat bran elevator 2 for temporary storage. A radar level gauge 301 is provided on the wheat bran buffer bin 3. When the radar level gauge 301 detects that the level in the wheat bran buffer bin 3 is relatively high and reaches or exceeds the set value, the radar level gauge 301 transmits a signal to the wheat bran elevator 2 and the automatic unpacking machine 1. The wheat bran elevator 2 stops lifting the wheat bran, and the automatic unpacking machine 1 closes the discharge port. When the radar level gauge 301 detects that the level in the wheat bran buffer bin 3 is lower than the set value, the radar level gauge 301 transmits a signal to the wheat bran elevator 2 and the automatic unpacking machine 1.
