Description

Technical Field

[0001] This utility model relates to the field of wine preservation technology, specifically to a structure for heat insulation of ceramic wine bottles. Background Technology

[0002] With the development of the high-end baijiu market, the control of the storage and transportation environment has become a core aspect of quality assurance. As a system of volatile organic compounds, the stability of baijiu's flavor compounds is extremely sensitive to temperature. Studies have shown that when the temperature of the baijiu exceeds 35℃, ester hydrolysis accelerates, and the oxidation rate of alcohols increases by 47%, directly leading to the decay of aroma components and the generation of harmful aldehydes.

[0003] Ceramic liquor bottles have become the mainstream packaging form for high-end baijiu (Chinese liquor) due to their excellent chemical stability, light-blocking properties, and cultural value. However, traditional ceramic liquor bottles have significant thermal protection defects in high-temperature environments (such as car trunks in summer, transportation and storage).

[0004] In high-temperature environments during summer, when bottled liquor is temporarily transported in a car trunk, the temperature inside can reach 60-75℃. The thermal conductivity of conventional ceramic materials is approximately 1.0-1.5 W / (m·K). At an ambient temperature of 60℃, the temperature of the liquor inside the bottle can rise by 22-25℃ within 30 minutes, far exceeding the safety threshold for liquor quality (≤0.5℃ / minute). Most existing liquor bottles are single-layer homogeneous ceramic structures. Although the addition of quartz sand and kaolin improves thermal shock resistance, this only addresses the mechanical cracking issue and cannot slow down the heat intrusion during the rapid temperature rise process. Utility Model Content

[0005] The purpose of this invention is to provide a structure for heat insulation of ceramic wine bottles, which improves the poor heat insulation effect of existing ceramic wine bottles by setting a composite heat insulation structure on the outside of the ceramic wine bottle.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A structure for heat insulation of ceramic wine bottles includes a ceramic bottle body, which is hollow and used to store liquid; a first heat insulation layer, a second heat insulation layer and a third heat insulation layer are sequentially disposed on the outside of the bottle body; the first heat insulation layer, the second heat insulation layer and the third heat insulation layer cover the bottle body and form a composite heat insulation structure on the surface of the bottle body;

[0008] The first heat insulation layer is adhered to the outer wall of the bottle; the first heat insulation layer is used to provide heat insulation for the side wall of the bottle.

[0009] The second heat insulation layer is coated on the first heat insulation layer; and the third heat insulation layer is wrapped around the second heat insulation layer; the second heat insulation layer forms a thermal barrier between the first heat insulation layer and the third heat insulation layer.

[0010] This invention features a composite insulation structure formed by three insulation layers: a first insulation layer, a second insulation layer, and a third insulation layer, all located on the exterior of the bottle. The first insulation layer is adhered to the outer wall of the bottle to provide thermal insulation against heat from the side walls. The second insulation layer is coated on top of the first insulation layer, and the third insulation layer is wrapped around it. The second insulation layer forms a thermal barrier between the first and third insulation layers. This composite insulation structure effectively prevents external heat from penetrating the bottle, ensuring the stability of the liquor's quality.

[0011] In this invention, the first heat insulation layer uses fermented pig blood as an adhesive and is adhered to the outer wall of the bottle. The specific method for preparing the fermented pig blood is as follows: potassium oxalate or sodium citrate is added to the pig blood to prevent coagulation, and then the cellulose is removed by filtration to produce defibrinated blood. The defibrinated blood is concentrated at low temperature and dried (50-60℃) to form blood powder, which is then rehydrated and mixed with 1-2% sodium hydroxide to form an adhesive. The adhesive is used to ensure a tight bond between the first heat insulation layer and the bottle.

[0012] Furthermore, the bottle body is provided with a bottle mouth, the closed end of the composite heat insulation structure abuts against the root of the bottle mouth, the bottle mouth is used to insert a bottle stopper, and the bottle stopper is positioned above the maximum liquid level in the bottle body.

[0013] The composite insulation structure completely encloses the bottle body and its bottom. The constriction point of the composite insulation structure is located at the top, specifically at the base of the bottle spout, where the bottle body connects to the spout. This composite insulation structure provides insulation for the entire bottle body while leaving the spout exposed for easy sealing with the cap.

[0014] Furthermore, the first heat insulation layer is a mulberry bark paper layer with a thickness of 0.6~1.0mm. The mulberry bark paper is provided in 1~3 layers, and two adjacent mulberry bark papers are bonded to each other.

[0015] The bottle is wrapped with mulberry bark paper, and adhesive is used to ensure a tight bond between the paper and the bottle, forming the first insulating layer. The mulberry bark paper used is specifically designed for sealing wine jars and is 0.3-0.6mm thick. Fermented pig's blood is used to bond the two layers of mulberry bark paper together.

[0016] Furthermore, the second insulation layer is an aerogel layer with a thickness of 2-3 mm, and the second insulation layer fills the gap between the first insulation layer and the third insulation layer.

[0017] After the mulberry paper layer is completely dry, aerogel is coated on the outside of the mulberry paper layer. After the aerogel solidifies, a second heat insulation layer is formed on the outside of the first heat insulation layer.

[0018] The aerogel layer uses ZDL-001 type aerogel thermal insulation coating, which is free of heavy metals such as lead, cadmium, mercury, and chromium. Before use, the aerogel coating is thoroughly stirred with an electric mixer until it becomes creamy. After the mulberry paper layer is completely dry, one coat of aerogel thermal insulation coating is rolled onto the outside of the mulberry paper layer. After the first coat is completely dry, a second coat is rolled on, and so on, for a total of 2 to 4 coats, until a 2 to 3 mm thick aerogel layer is formed after drying.

[0019] Furthermore, the third insulation layer is a mud and lees sealing layer, and the thickness of the third insulation layer is 3~4mm. The third insulation layer prevents the second insulation layer from contacting the air.

[0020] After the second insulation layer is completely dry, the mixture of mud and lees is applied to the outside of the second insulation layer and dried to form the third insulation layer. The third insulation layer wraps the first and second insulation layers inside, so that the first, second and third insulation layers are tightly connected to form a composite insulation structure, which effectively isolates external heat from entering the bottle, avoids affecting the quality of the liquor, and ensures the stability of the liquor quality.

[0021] Furthermore, a skin layer is adhered to the outer surface of the third insulation layer.

[0022] The thickness of the epidermis is 1~3mm.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This invention utilizes a composite insulation structure formed by incorporating a first, second, and third insulation layer on the exterior of the bottle. This structure effectively prevents external high temperatures from penetrating the bottle and affecting the quality of the liquor inside, thus ensuring the stability of the liquor's quality. The invention features a simple structure, uses safe materials, and contains no harmful components, further guaranteeing the stability of the liquor's quality. Attached Figure Description

[0031] The first heat insulation layer 3 is adhered to the outer wall of the bottle body 1; the first heat insulation layer 3 is used to provide heat insulation for the side wall of the bottle body 1.

[0032] The second heat insulation layer 4 is coated on the first heat insulation layer 3; and the third heat insulation layer 5 is wrapped around the second heat insulation layer 4; the second heat insulation layer 4 forms a thermal barrier between the first heat insulation layer 3 and the third heat insulation layer 5.

[0033] This utility model forms a composite heat insulation structure by setting a first heat insulation layer 3, a second heat insulation layer 4 and a third heat insulation layer 5 on the outside of the bottle body 1. The first heat insulation layer 3 is adhered to the outer wall of the bottle body 1 to provide heat insulation for the side wall of the bottle body 1; the second heat insulation layer 4 is coated on the first heat insulation layer 3; and the third heat insulation layer 5 is wrapped on the second heat insulation layer 4; the second heat insulation layer 4 forms a heat barrier between the first heat insulation layer 3 and the third heat insulation layer 5.

[0034] This invention forms a composite heat insulation structure by setting a first heat insulation layer 3, a second heat insulation layer 4 and a third heat insulation layer 5 on the outside of the bottle body 1. This prevents external high temperatures from penetrating into the bottle through the bottle body 1 and affecting the quality of the liquor inside, thus effectively ensuring the stability of the liquor quality inside the bottle.

[0035] Example 2

[0036] like Figure 1-3 As shown, based on Embodiment 1, the bottle body 1 is provided with a bottle mouth 2.

[0037] A first heat insulation layer 3, a second heat insulation layer 4, and a third heat insulation layer 5 are formed on the outside of the bottle body 1, and the three heat insulation layers are bonded together in sequence to form a composite heat insulation structure. Adhesive is applied to mulberry bark paper, and the bottle body 1 is completely wrapped with the mulberry bark paper.

The number of mulberry bark paper layers in the first heat insulation layer can be 1, 2 or 3. In principle, the total thickness of the mulberry bark paper layer is 0.6~1mm, which can ensure good heat insulation effect.
