Description

Technical Field

[0002] Filling equipment is a kind of equipment used to distribute liquid materials according to set specifications, capacity or weight during the production and processing of liquid materials. It is usually composed of a liquid storage cylinder, a filling nozzle, a filling mechanism, etc. It has the characteristics of being simple and reliable, easy to operate, flexible and changeable, and efficient and fast. During the liquid filling process, due to the characteristics of certain liquids, filling operations, and environmental changes, the liquid in the liquid storage tank is prone to foam and float on the upper layer. The presence of foam will have many adverse effects on the filling quality. Foam will cause inaccurate filling volume. If the foam surface is used as the filling standard, the actual liquid volume may be insufficient, resulting in inconsistent product specifications. Foam will also introduce air, increase the risk of liquid oxidation, and affect product stability and shelf life. Defoamers are often used to remove the upper layer of liquid foam. Defoamers are equipment specially designed to deal with foam problems. Through mechanical stirring, centrifugal force, pressure changes, etc., the stability of the foam is destroyed and the foam is broken to achieve the purpose of defoaming.
