Embodiment 1

[0026] Put 10,000 extra-grade natural corks into the drum, and heat while rolling, so that the corks are evenly heated and preheated to a surface temperature of 30°C; spray 5L on the surface of the preheated corks with a mass percentage concentration of 14 % of acrylic resin aqueous solution, the spraying rate is 1.0L / min, and the spraying pressure is 0.3MPa; the roller is rolled to make the acrylic resin aqueous solution evenly rolled on the cork, and heated until the surface temperature of the cork is 60°C , keep the drum rolling, and keep drying at 60°C for 10 minutes, and let it cool down naturally.

Embodiment 2

[0028] Put 10,000 extra-grade natural corks into the drum, heat while rolling, so that the corks are evenly heated and preheated to a surface temperature of 40°C; spray 5L on the surface of the preheated corks with a mass percentage concentration of 28 % of acrylic resin aqueous solution, the spraying rate is 1.0L / min, and the spraying pressure is 0.2MPa; the roller is rolled to make the acrylic resin aqueous solution evenly rolled on the cork, and heated until the surface temperature of the cork is 50°C , keep the drum rolling, and keep drying at 50°C for 10 minutes, and cool naturally; that is.

Embodiment 3

[0030] Put 10,000 extra-grade natural corks into the drum, and heat while rolling, so that the corks are evenly heated and preheated to a surface temperature of 20°C; spray 3L on the surface of the preheated corks with a mass percentage concentration of 22 % of acrylic resin aqueous solution, the spraying rate is 1.0L / min, and the spraying pressure is 0.4MPa; the roller is rolled to make the acrylic resin aqueous solution evenly rolled on the cork, and heated until the surface temperature of the cork is 70°C , keep the drum rolling, and keep drying at 70°C for 5 minutes, and cool naturally; that is.

Abstract

The invention discloses a surface treatment process of a natural soft wooden plug. The process comprises the following steps: placing the soft wooden plug into a roller, and preheating; coating a filming material on the surface of the preheated soft wooden plug; heating; drying; naturally cooling; transferring the cooled soft wooden plug into the roller, and preheating; coating liquid wax on the surface of the soft wooden plug; rolling under room temperature; standing; then sprinkling semi-solid wax on the surface of the soft wooden plug; rolling under the room temperature; naturally cooling to obtain the natural soft wooden plug. According to the process, the soft wood plug is covered with a film under a special condition, so that the problem of pigment leaching from the natural soft wooden plug can be solved; in addition, the surface of the natural soften wooden plug is subjected to film covering and wax spraying through special materials and process, so that the problems of severe pigment leaching of the natural soft wood plug and high leaking ratio of bottled grape wine in the storing and transporting process can be solved, and as a result, the quality of the soft wooden plug can be improved. The process is simple, easy to operate, and applicable to industrial production and popularization and application.

Description

technical field [0001] The invention relates to the field of wine packaging equipment, in particular to a treatment process for the surface of natural cork stoppers. Background technique [0002] High-quality wine not only depends on high-quality grape raw materials and processing technology, but also depends on scientific preservation after bottling. In this process, wine corks play a vital role. So far, cork is still the most widely used, oldest and most effective sealing material for wine corks in the world. The growth of cork mainly grows near the Mediterranean Sea, where the local humidity is 60-70% and the temperature is around 15-25°C. Its processing and use are more suitable for the local climate environment. If the processing and use environment are changed, the research and development personnel need to re-study the new processing technology to meet the stability of the cork stopper in later use. At present, the natural cork used in bottled wine in our country h...
