Description

Technical Field

[0001] This utility model relates to the technical field of hydrogel preparation equipment, specifically a defoaming device for preparing hyaluronic acid hydrogel. Background Technology

[0002] Hyaluronic acid, also known as hyaluronic acid, is widely used in beauty, medical, and health care fields. Its production process generally includes hyaluronic acid extraction and purification, followed by mixing sodium hyaluronate with other additives in a specific ratio according to product requirements to obtain a mixture, which is then gelled. During the production of hyaluronic acid hydrogels, air bubbles are inevitably generated in the mixture during the mixing process. Furthermore, the high viscosity of sodium hyaluronate increases the probability of bubble formation. Currently, commonly used defoaming processes include vacuum defoaming, chemical defoaming, and physical defoaming. Vacuum defoaming requires expensive equipment and has relatively low processing efficiency; chemical defoaming requires the addition of chemical defoaming agents, making it unsuitable for cosmetics and medical products; commonly used physical defoaming often involves low-speed stirring, resulting in unstable defoaming effects.
