Manufacture method of silicone rubber wine stopper

Abstract

The invention provides a manufacture method of a silicone rubber wine stopper, belonging to the technical field of a wine stopper manufacture method. The method comprises the following steps of: processing a bottle cap mold and a bottom stopper mold according to design drawing; injecting a silicone rubber material into the molds, wherein the mold temperature is 140-170 DEG C, and is kept for 5-10 minutes; performing vulcanization on a qualified product at 180-210 DEG C for 3-5 minutes; performing cleaning and disinfection on the qualified product; and instantly packaging the cleaned and disinfected product. The environmental protection performance, good high-and-low temperature performance, hydrolytic stability, weather resistance, physical inertia and sealing property of the food-grade silicone rubber are utilized to manufacture the wine stopper replacing a plastic product in an existing wine industry, so that harmful substances, such as a plasticizer, in wine is eliminated. The plasticity of the food-grade silicone rubber is utilized to be adaptive to the structure of a wine bottle neck; and the method can be widely popularized and applied on the premise of not increasing winery costs.

Description

technical field [0001] The invention relates to a production method of silica gel wine stopper, which belongs to the technical field of wine stopper production method. Background technique [0002] In May 2011, Taiwan discovered for the first time that the food additive "clouding agent" contained a plasticizer (DEHP). According to Taiwan News, at least 40 midstream and downstream manufacturers were victimized. As of May 24, food products that have been recalled or taken off shelves in Taiwan include nearly 460,000 bottles of sports drinks, fruit juices, and tea drinks, 20,000 kilograms of fruit juices, jams, and yogurt powder, and more than 130,000 boxes of probiotic powder. Taiwan's Department of Health stated that the number of problematic products is expected to rise sharply, and the direct economic loss will reach 100 million yuan. [0003] Plasticizer is a kind of emulsifier, which is often used in fruit juice, beverage, jelly and yogurt powder, so that the beverage c...

Problems solved by technology

[0004] Plasticizers are also automatically produced in plastic products, so that they are already contained in food without people's awareness. Some wineries in China use plastic filling supplies in the production and filling process, such as delivery Wine pipes, wine barrels, etc., plasticizers are slowly produced during the production process, and the long-term use becomes more and more serious. At the same time, after the wine is filled, plastic wine stoppers are used to make the plasticizers in the wine The ingredients of plasticizers continue to increase, so the problem of plasticizers exceeding the standard appears
