Stage Dryer T
NEUE HERBOLD stage dryer Series T are specially designed for gentle drying of PET plastic regrinds.
They are suitable for deposition of the surface moisture from the granular plastics. Depending on the temperature, size and structure of the starting product, a surface residual moisture content of about 1 to 2 weight percent is achieved.
Thermal Dryer TT
NEUE HERBOLD – Thermal Dryer TT Series is a down stream unit after the mechanical dryer. It is designed to achieve a final material moisture of 3% or less.
The material is fed through a cyclone. A heater supplies hot air on a continuous basis and is equipped with a temperature control unit. The required temperature is determined by the rest moisture of the various materials as well as the required through put rate. After completion of the drying process the material is blown into film silos (FS Series) or into big-bags for further treatment.
Mechanical Dryer TM
NEUE HERBOLD – mechanical Dryer TM Series are used as a downstream component after a washing process. It is used for surface drying of the material fraction primarily for film flakes, granulate from PET bottles and other rigid types of plastics.
The wet material fraction is fed into the upper hopper located on the end of the dryer housing. The rotor of the mechanical dryer transports the material through the dryer from the inlet side to the outlet port. The angular degree of the rotor flights and the rotor speed are detrimental for the material duration time in the dryer.
