Description

Technical Field

[0001] The utility model relates to the technical field of wooden covers, in particular to a pine log cover for cellaring white liquor. Background Art

[0002] After newly brewed, white liquor generally has problems such as strong irritation, heavy pungency, and uncoordinated taste. Therefore, it will be subjected to cellar storage treatment for a certain period of time. During the storage process, oxygen in the air can penetrate through the cylinder wall and contact the liquor, slowly oxidizing substances such as alcohols in the liquor, promoting the formation of esters, and making the liquor produce a mellow and mellow taste. This oxidation process helps to gradually achieve balance among alcohols, acids, and esters in the liquor, not only enhancing the aromatic smell of the liquor, but also making it more gentle, soft, and the aroma more prominent. And there will be various physical or chemical reactions during the whole cellar storage process. While improving the liquor body and flavor, it will also affect the content of volatile substances such as by-products and pollutants methanol, acetaldehyde, furfural, acetal, fusel oil, etc. generated during the brewing and storage processes. Currently, white liquor cellar storage is generally carried out in pottery jars or pottery vats covered with nylon paper. However, although covering with nylon paper effectively avoids the evaporation of white liquor and excessive oxygen contact, the volatile substances gather when encountering the nylon paper and then return to the white liquor again, which will have a certain impact on the taste and flavor of the white liquor and the content of harmful substances.

[0003] Existing research has found that methanol in white liquor is very harmful to human health. After metabolism in the human body, it will produce formaldehyde with stronger toxicity. Formaldehyde will damage organs such as the nervous system, liver, and kidneys of the human body, and even cause blindness and death; after metabolism of fusel oil in the human body, it will produce ketone substances with very strong toxicity. This substance will damage the nervous system of the human body and also cause symptoms such as headache, nausea, and vomiting; acetaldehyde is one of the main substances leading to alcohol poisoning. When its content is high, it will cause the liquor to be pungent and throat-irritating, and has an anesthetic effect on the nervous system, causing symptoms such as a burning sensation in the throat, dizziness, and vomiting. Long-term and excessive intake may also increase the risk of cancer; etc.

[0004] Based on the above, how to effectively reduce the content of harmful volatile substances and other defects during the cellar storage of white liquor and improve the quality and safety of white liquor is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] In view of this, the utility model provides a log cover for cellaring white liquor.

[0006] In order to achieve the above-mentioned invention purpose, the utility model provides the following technical solutions:

[0007] A log cover for storing Chinese liquor in a cellar, comprising a cover handle, a cover body and a wooden frame. The cover handle is fixedly connected to the upper surface of the cover body, and the wooden frame is fixedly connected to the lower surface of the cover body, and the long side of the cover handle is parallel to the long side of the wooden frame;

[0008] The wooden frame includes a top wooden board and side wooden boards. The top wooden board is in contact with the lower surface of the cover body. The sides of the top wooden board are respectively connected to the upper ends of the side wooden boards, and the side wooden boards are sequentially connected to form an integral structure.

[0009] Preferably, the central points of the cover handle, the cover body and the wooden frame coincide.

[0010] Preferably, the sides of the side wooden boards are connected by butt joint.

[0011] Preferably, it further includes a connecting rope arranged on the wooden frame, and both ends of the connecting rope are connected to any two parallel side wooden boards.

[0012] Preferably, the cover handle, the cover body and the wooden frame are all made of pine wood.

[0013] Preferably, the top wooden board is a regular polygon.

[0014] By adopting the above technical solutions, the present utility model provides a log cover for storing Chinese liquor in a cellar. Compared with the prior art, it has the following beneficial effects:

[0015] In the present utility model, the cover handle, the cover body and the wooden frame are all made of pine wood, which can effectively promote the action of the medicinal value components and aromatic substances in pine trees and pine branches on the Chinese liquor body, making the liquor body have a unique pine wood fragrance; moreover, pine wood has good adsorption and hygroscopicity, and can effectively adsorb harmful gas methanol during the storage of Chinese liquor, improving the quality and safety of Chinese liquor.

[0016] In the present utility model, the cover body is combined with the wooden frame. While giving full play to the role of the pine wood material itself, substances with adsorption or hygroscopic properties can be placed in the wooden frame, further promoting the effective adsorption of harmful gas methanol during the storage of Chinese liquor and improving the safety of Chinese liquor. In addition, the setting of the connecting rope on the wooden frame can play a fixing role to prevent the substances placed in the wooden frame from falling. BRIEF DESCRIPTION OF THE DRAWINGS
