Method for controlling rusting of bottle cap by detecting water residue in skirt teeth of bottle cap

Abstract

The invention discloses a method for controlling rusting of a bottle cap by detecting water residue in skirt teeth of the bottle cap. The method comprises the following steps of: (1) preparing, i.e., selecting precision test paper with a pH (Potential of Hydrogen) range of 5.5-9.0 and equally dividing each test paper into 10 equal parts; (2) setting a judgment standard for water residue of the skirt teeth of the bottle cap; and (3) detecting a sample to be detected, calculating the water residue R of the skirt teeth of the bottle cap, distinguishing qualified products from unqualified products, handling the unqualified products which do not meet the standard through an adjustment and control method, rechecking until the products are qualified and then releasing. The invention establishes a method for detecting the water residue in the skirt teeth of the bottle cap; and parameters including blowing air speed, temperature and direction of a bottle cap skirt tooth blowing device behind a spray type pasteurization machine can be adjusted by a result which is obtained on the basis of the judgment standard and the detection method, so that the rusting situation of the skirt teeth of the bottle cap can be reduced and even avoided, the economic loss of a company is reduced, and the brand of the company and the satisfaction of customers are maintained.

Description

technical field [0001] The invention relates to a method for controlling the corrosion of the beer bottle cap, in particular to a method for controlling the corrosion of the beer bottle cap by detecting the amount of residual water in the skirt teeth of the beer bottle cap. Background technique [0002] Beer is made from barley malt made by germinating barley as the main raw material, which is brewed by saccharification, adding hops, and brewing yeast fermentation. It contains carbon dioxide, low alcohol concentration, and sparkling brewed wine. [0003] At present, the main material of domestic beer bottle caps is tinplate, which is deformed under force during the cap making process and capping process, and there will be slight coating breakage and iron leakage. After the bottle cap that has lost its coating protection is sprayed with hot water by the pasteurization machine, it will react with oxygen in the air under humid conditions, which will cause rust, and then form ru...

Problems solved by technology

To solve this problem, it is first necessary to be able to quantitatively detect the amount of residual water in the skirt teeth of the bottle cap. At present, there is no such detection method in the industry.
