Spray dryer is a kind of drying equipment widely used in food, pharmaceutical, chemical and other industries. It can quickly dry liquid raw materials into powder products. Spray drying technology has become an indispensable part of modern industrial production due to its advantages such as high efficiency, uniformity and controllability. This article will introduce the definition, working principle, components, application fields, advantages and precautions of spray dryer in detail. 1. Definition of Spray Dryer             Spray dryer is a device that uses spraying to spray liquid materials into droplets through high-speed centrifugal or high-pressure nozzles, and evaporates water instantly when in contact with hot air, eventually forming a powder or granular dry product. This drying method can complete large-area liquid evaporation in a short time, and is particularly suitable for drying heat-sensitive materials. ...

             The reverse osmosis pure water system uses reverse osmosis technology to treat water, such as removing impurities, organic matter and inorganic salts in water, so as to obtain high-purity water. It is an advanced water treatment equipment. The entire reverse osmosis pure water equipment is mainly composed of pretreatment, reverse osmosis, post-treatment, cleaning, and electrical control. The pretreatment link includes raw water pumps, dosing devices, quartz sand filters, activated carbon filters, precision filters, etc. It is widely used in various fields such as pharmaceuticals, chemicals, electronics, and food. The principle of reverse osmosis pure water equipment              Based on the reverse osmosis membrane, source water is introduced into the membrane and cross-flow is used to flush the concentration components, providing a channel for the transfer of water. This process involves applying high ...
