Centrifugal Spray Dryer

The centrifugal spray dryer is a type of spray dryer. It uses a high-speed centrifugal atomizer to atomize the material liquid, and allows the atomized material liquid to form extremely small droplets and other forms to be mixed with hot air at a predetermined temperature. Full contact, complete dehydration and drying of materials in a very short time, and finally collected by the powder collection device.

Description Of Centrifugal Spray Dryer

Centrifugal spray dryer is widely used process in the liquid forming process. It is suitable for producing powdery and granular solid products from solutions, emulsions, suspoemulsions and paste liquids. Therefore, when the granule size distribution, residual moisture content, bulk density and granule shape of the finished product meet precise standards, centrifugal spray dryer is an ideal drying process. The spray dryers can be widely used in food, chemicals, pharmaceutical , ceramics and other industries.

Specification Of Centrifugal Spray Dryer

Working Principle Of Centrifugal Spray Dryer

Liquid materials enter the nozzle through the feeding system and are atomized into tiny droplets under high-speed rotation. Simultaneously, hot air generated by the hot air blower enters the drying chamber through the hot air pipeline, fully contacting the tiny droplets to rapidly dry them. The dried product is collected by the material collection device, completing the entire drying process.

Hot Air System

The hot air system is another important component of centrifugal spray drying equipment, mainly composed of a hot air blower, air filter, hot air pipeline, etc. The hot air blower generates hot air, which is transported to the drying chamber through the hot air pipeline to provide heat for the drying of liquid materials. The air filter is responsible for filtering impurities in the air to ensure the purity of the hot air.

Drying Chamber System

The drying chamber is the main working area of centrifugal spray drying equipment, where liquid materials complete the drying process. The drying chamber typically has a cylindrical structure with a hot air distributor and a material collection device inside. The hot air distributor ensures even distribution of hot air in the drying chamber, while the material collection device collects the dried product.

Spray System

The spray system is the core component of centrifugal spray drying equipment, mainly consisting of a nozzle, a rotation mechanism, and a feeding system. The nozzle is the key component of the spray system, atomizing the liquid material into tiny droplets through high-speed rotation to achieve rapid drying. The feeding system is responsible for supplying liquid material evenly and continuously to the nozzle.

Exhaust Gas Discharge System

The exhaust gas discharge system mainly consists of a dust collector and a fan, effectively reducing environmental pollution caused by spray emissions.

Control System

The control system is the "brain" of centrifugal spray drying equipment, responsible for functions such as equipment start-stop, parameter adjustment, and fault monitoring. The control system is typically controlled by PLC or touchscreen, enabling automated and intelligent operation.
