Embodiment Construction

[0012] Beer foam is an important indicator of beer quality. It has the characteristics of foamability, stability and glass hanging. Among them, the formation of foam includes two-phase foam and multi-phase foam. Only the solution can form obvious foam. According to the Gibbs adsorption formula, the solute (surfactant) in the solution is adsorbed on the gas-liquid interface. The bubbles formed by beer form a certain amount of active substances on the surface of beer, and these active substances accumulate to form beer bubbles. The smaller the bubbles, the more active substances are formed and the stronger the binding capacity of these active substances. In order to realize on-line automatic detection on the production line, the present invention, after investigating and statistically analyzing the data of a large number of breweries, concluded that the foam of beer is an important indicator of beer quality. The bottled mature beer behind the sterilizer conducts online foam ana...

Abstract

The invention discloses a foam-appearance-based on-line beer detection method. At a first detection station, a backlight source is adopted for detecting, and an image of the neck region of a beer bottle is captured by a camera, so that the height and the shape of foam can be detected; and at a second detection station, the top and the side face of the beer bottle is lighted, and an image is captured by a camera which has the same direction as a light source at the side face, so that the size, the fineness and the smoothness of the foam can be detected. After the method is used, according to the detection on the appearance of the foam at the neck of the beer bottle, the quality of beer can be analyzed, and the method is high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of on-line detection on automatic production lines, and in particular relates to an on-line detection method for beer based on foam appearance. Background technique [0002] In recent years, with the improvement of consumption level and the improvement of relevant laws and regulations, product quality has become more and more important in the beer industry. Due to the production process and packaging technology, there may be foreign matter in the bottled beer after filling, the cap is not tight, and the bottle is damaged. These problems have seriously affected the product quality and reputation, so the detection link is during the production process. An important part of it is a key link in controlling product quality. At present, the online detection methods of beer are almost all based on manual visual inspection. Behind the automated assembly lines of some breweries, many inspection workers can often be ...
