Patented rotor spraying system

How the rotors work
A liquid is carried into the center of a rapidly rotating rotor via a supply pipe Centrifugal force accelerates the liquid outwards to a specially shaped plate edge, from where the fine droplets of the spray application fly. The diameter of the droplets depends on the viscosity and surface tension of the respective sprayed liquid and is between 30 and 70 micrometers.

Product category: Dryers

HOT AIR DRYING

There are three ways of transferring heat:

Convection
Conduction
Radiation

Convection drying is hot-air drying.
Our dryers are of a modular design. Dryers and equipment are connected only by pipelines, allowing them to be modified easily. For example, a heating medium can be changed without major effort.

The drying process determines the dryer. Many variables influence the design of a dryer. The following are cited as examples:

The necessary treatment time
The transport speed of the product
The properties of the product
The behavior during drying of the layer being dried
The maximum drying temperature for each drying section
The required amount of energy
The available installation space
The heating energy to be used
The amount of dirt
The production system / technical system
The product change frequency

The dryer constructor is able to design an optimum dryer on the basis of the housing shape (door design, position of the connections, web travel), nozzle geometry, air volumes and temperatures. The material and surface of the transport system are adapted to the drying process.

Our dryers are ideal for drying web and curved products. The liquid to be evaporated can be water, but also a solvent or a solvent combination and should not be applied in too large quantities.
