  • Cascade extracting and solvent refreshing method for recycling jelly cables
    Patent number: 7011713
    Abstract: The method of continuously collecting jelly compounds from jelly filled cable is performed by recycling operation of a solvent by repeatedly heating, cleaning and condensing the recycling solvent used to deprive the jelly compounds of the jelly filled cable. The solvent can be retrieved for reuse unlimited times, and the collected jelly compounds can be purified for reuse too. The method is energy saving with less consumption of solvent. Absolutely no worry of an additional public nuisance.
    Type: Grant
