Description

Technical Field

[0001] This utility model relates to the technical field of sealing cellar devices, and in particular to a novel sealing cellar device for a strong-aroma type cellar. Background Technology

[0002] In the brewing process of strong-aroma baijiu, the airtightness of the fermentation pits is one of the key factors affecting the fermentation effect. The core function of sealing the fermentation pits is to isolate them from the outside air, maintain an anaerobic environment inside the pits, and simultaneously maintain temperature and humidity, providing stable conditions for the metabolic activities of microorganisms. Good sealing not only prevents contamination by other microorganisms but also promotes the enrichment and synergistic effects of specific functional microbial communities within the pits, thereby ensuring the efficient saccharification, fermentation, and esterification reactions of the mash, ultimately forming the unique flavor compounds of strong-aroma baijiu. Furthermore, the integrity of the sealing directly affects the aroma-producing efficiency of the mash and the quality of the final product, making it a crucial and indispensable step in the brewing process.

[0003] The traditional method of sealing fermentation pits in northern China involves covering the pit cap with a layer of food-grade PE plastic sheeting, followed by a thick layer of clay mud, and then brushing the surface with mud and water to keep it moist and prevent the clay mud from cracking. However, this traditional method has many drawbacks: the large amount of clay mud used increases labor intensity and soil input costs; when opening the pit, using a shovel to remove the clay mud can easily damage the food-grade PE plastic sheeting underneath, leading to decreased sealing when using the damaged plastic sheeting again later, or frequent replacement of the food-grade PE plastic sheeting, thus increasing the input cost of the food-grade PE plastic sheeting; the use of a large amount of clay mud also results in a poor sanitary environment around the pit, making cleaning difficult; and in the dry climate of northern China, the clay mud is more prone to cracking, affecting the sealing and fermentation effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a novel sealing device for a strong-aroma fermentation pit. This utility model is achieved through the following technical solution:

[0005] A novel sealing device for a strong-aroma fermentation pit includes a pit, with a pit opening at the top. The pit opening is surrounded by ground, and a trench is formed around the pit opening on the ground. The bottom of the trench is "V"-shaped. An arched sealing cover is laid at the pit opening. An integrated cover is provided around the sealing cover, which is embedded in the trench. A clay sealing ring is laid inside and above the trench embedded in the cover. The clay sealing ring extends upward to the surface of the sealing cover. A protective layer is provided on the surface of the clay sealing ring. An insulation pad is placed on top of the protective layer, and an insulation blanket is placed on top of the insulation pad.

[0006] As a preferred embodiment, the sealing cover is made of PE plastic sheeting.

[0007] As a preferred embodiment, the width of the clay sealing ring on the surface of the sealing cover is not less than 10cm.

[0008] As a preferred embodiment, the protective layer is a PE plastic film.

[0009] As a preferred embodiment, the insulation pad comprises a felt, the surface of which is attached with a layer of tin foil.

[0010] As a preferred embodiment, the inner layer of the insulation blanket is made of multiple layers of felt, and the outer layer is made of waterproof fabric.

[0011] As a preferred embodiment, the distance between the outer edge of the insulation blanket and the edge of the cellar opening is not less than 15cm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a ground trench around the opening of the pit, with the bottom of the trench being "V" shaped. An arched sealing cover is laid at the opening of the pit, and an integrated cover is provided around the sealing cover. The cover is embedded in the ground trench, and a clay mud sealing ring is laid inside and above the ground trench embedded in the cover. This can greatly improve the sealing performance and prevent the inside of the pit from contacting the external environment.

[0013] The protective layer not only prevents the clay from cracking due to the dry weather in the north, but also prevents the clay from soiling the thermal insulation quilt. Attached Figure Description
