    Thin-film Dryer - Horizontal & Vertical

     

    Gentle drying and high product purity when processing heat-sensitive media

    GIG Karasek manufactures both vertical and horizontal thin-film dryers, which are primarily used when gentle drying of heat-sensitive media is required.
     
    As our dryers are based on the principles of our proven thin-film evaporator technology, our thin-film dryers are both powerful and economical.

    ADVANTAGES

    • High product purity
    • Minimal product loss
    • Highest dry matter content
    • Gentle drying thanks to short dwell time and permanent product circulation
    • Hardly any deposits on the heating surfaces due to mechanical cleaning
    • Reduced maintenance work thanks to clever design of the bearing and shaft seals

    Functional principle
    The medium to be dried is distributed continuously around the entire circumference of the heating wall. Special wiper elements continuously renew the contact between the substance and the heating wall and ensure that the product flow continues.
     
    As the solid rotor blades do not touch the heating jacket (defined gap), incrustation or blockage of the heating surface is avoided and liquid substances can be dried to powder form despite the gentle process.
