Hyaluronic Acid (HA), also known as hyaluronic acid, is an acidic mucopolysaccharide. In appearance, hyaluronic acid is a white, odorless, tasteless, hygroscopic powder. In aqueous solution, due to its hydrophilicity, it can absorb and retain a large amount of water, forming a viscous, elastic gel-like substance. The viscosity of its solution is related to its concentration, molecular weight and other factors, generally speaking, the higher the molecular weight, the higher the viscosity of the solution. Hyaluronic acid is one of the most popular soft tissue fillers, and can be used to fill facial wrinkles, lip augmentation, rhinoplasty and other micropigmentation projects. Despite the increasingly fierce competition in the market, with the increasing consumer demand for medical aesthetics and the continuous innovation of hyaluronic acid technology, such as the application of new cross-linking technology and the combination with other active materials, there is still a large space for its growth in the field of medical aesthetics and plastic surgery. As an ideal natural moisturizing factor, hyaluronic acid absorbs and locks in a large amount of water to keep the skin hydrated and smooth, and is one of the core ingredients of many skin care products. With consumers' increasing demand for skin care and the pursuit of high-quality skin care products, the application of hyaluronic acid in skin care products will become more widespread, and the market size is expected to continue to expand.
The production process and technological development trend of hyaluronic acid is toward a more efficient, environmentally friendly, intelligent direction, while constantly innovating product forms and service modes to adapt to changes in market demand and promote industrial upgrading. Jiangsu Longxin develops hyaluronic acid spray dryer around improving efficiency, ensuring quality, enhancing environmental performance, improving operation convenience and safety, etc. It adopts high-efficiency heat exchanger, energy-saving motor, etc. to reduce energy consumption and improve energy utilization rate. With its advantages of high efficiency, flexibility, environmental protection, etc., it improves the production efficiency while guaranteeing the quality of products and becomes an indispensable and important equipment in the production of hyaluronic acid. These advantages not only meet the current market demand, but also provide a solid foundation for future development.
Hyaluronic acid spray dryer working principle
(1) Air heating and conveying: the air first passes through the filter to remove the impurities and dust in it, and then enters the heater. In the heater, the air is heated to a set temperature and becomes hot air. The hot air then enters the air distributor at the top of the centrifugal spray dryer and enters the drying chamber evenly in a spiral shape.
(2) Material Liquid Atomization: The material liquid is filtered by the material liquid tank through the filter and then sent to the centrifugal atomizer on the top of the dryer by the pump. The centrifugal atomizer generates strong centrifugal force through high-speed rotation, and disperses the material liquid into very small mist droplets. These atomized droplets have a large surface area and can fully contact with the hot air, thus accelerating the drying speed.
(3) concurrent contact drying: the atomized material liquid and hot air in the drying room concurrent contact, that is, the two flow in the same direction. The hot air will transfer the heat to the fog droplets, so that the droplets of water on the surface of the rapid evaporation. Due to the large surface area of the droplets, the water evaporation rate is very fast, in a very short period of time (generally only 5 to 15 seconds), the water in the droplets will be evaporated, thus drying the material into a finished product.
(4) Finished product collection and exhaust gas discharge: a part of the dried finished product falls directly into the bottom of the drying tower, and the other part is collected by the cyclone separator with the airflow. The cyclone separator utilizes centrifugal force to separate the finished product from the exhaust gas, the finished product is collected into the designated container, while the exhaust gas is discharged by the fan. Users can select the appropriate heating method as well as dust collection and dust removal method according to the actual situation to meet the production demand and environmental protection requirements.
