  • In radiant energies such as infrared (IR), high frequency (HF) and microwaves (MW), energy is transferred by thermal radiation. Note that there is a difference between drying and curing: drying requires the raising of the solvent molecules to or above the latent heat of evaporation, whereas curing techniques provide the energy for cross-linking ( polymerisation) or other reactions. The drying and curing of coatings are discussed in the STS BREF.
    These technologies are applied in industrial production processes to heat products and thus, can be applied in drying processes. Radiant energies can be used alone or in combination with conduction or convection.

    輻射熱能如紅外線、高週波、微波等,其能量由輻射熱傳導出去。要注意烘乾(drying)與硬化(curing)是不同的意義:乾燥技術是要將溶劑分子的溫度提高到超過其蒸發潛熱而蒸發;硬化技術是提供能量給溶劑分子產生連鎖反應(聚合作用)或其他的反應作用。塗層烘乾技術和硬化技術參見STS BREF (surface treatment using organic soluvents)

  • None reported.

  • Radiant energies, in particular I R, can be used in retrofitting of installations or to boost the production line, coupled with convection or conduction.
    In spite of their advantages (speed of action, quality of final products, energy savings), the use of radiant energies is not common in industrial applications, today known a s having a great energy savings potential.
    IR can be used in:
    ●curing of paint, ink and varnish
    ●drying of paper, paperboard, pre-drying of textiles
    ●drying powder in the chemical and plastics industries.
    HF can be used in the drying of:
    ●massive (monolithic) products: textiles (reels of wire), ceramics
    ●powder in the chemical industry.
    MW can be used in the drying of:
    ●massive (monolithic) products (wood, agro-industry) or flat products
    ●chemical and pharmaceutical products (under vacuum).


  • Investment is generally more expensive (20-30 %) than conventional techniques.
