Most engineering plastics spray dryers have hygroscopicity. When plastics Chinese herbal extracts spray drying equipments are taken out from moisture-tight sealed packaging dryer bags and exposed to the atmosphere, they begin to absorb moisture from the atmosphere. Hot-air drum dryers, because they use dry air to dry plastic, cannot prevent the plastic from absorbing moisture. Therefore, the dehumidifying airflow spray dryer gradually replaced the traditional hot air jet spray dryer, which greatly improved the quality of plastic products.
Air drying equipment
Using the Niagas NSD Dryer Series Dehumidification Airflow Spray Dryer High-speed Centrifugal Decontamination of Engineering Plastics The process of desiccant drying in a spray dryer is: When moist air passes through the honeycomb wheel, it is absorbed by water, and then passes through a heating tube and the air heats up. After entering the drying drum (drying drum connected to the drying air flow spray dryer gas is a down-blowing flared tube spray drying machine), the dehumidified and dried air of the engineering plastic is returned. After dehumidification in the hive wheel, the regeneration zone of the hive wheel is also working at the same time. This project is carried out at the same time, thus stabilizing the dew point of the air inside the drying drum at -40C.
NSD series dehumidification air jet pressure spray granulation drying fog drying equipment is equipped with automatic feeding function, reducing labor force and increasing production efficiency.

The airflow spray dryer has a high degree of automation and is flexible in operation (the granularity of the finished product can be controlled). Particularly suitable for use in solutions, emulsions, pastes, suspensions and even viscous materials can also be dried. Particularly suitable for medium or experimental scale drying of materials.
