Abstract: The present invention relates to a system for reducing a content of 5-hydroxymethylfurfural in a high fructose syrup, including an ion exchange positive column and an ion exchange negative column for performing cation and anion removals in sequence for an F42 high fructose syrup obtained by performing isomerization and first decolorization, a heat exchanger for performing heat exchange and temperature reduction for an F55 high fructose syrup obtained by performing concentration, chromatographic separation, blending and second decolorization in sequence for the F42 high fructose syrup subjected to ion exchange, a mixed bed column for performing purification for the heat-exchanged F55 high fructose syrup, and an evaporation tank for performing concentration for the F55 high fructose syrup subjected to mixed bed treatment. The present invention further provides a method of reducing a content of 5-hydroxymethylfurfural in a high fructose syrup.

Abstract: An apparatus and method for cleaning polymer film are provided and include a support assembly for supporting the polymer film to be cleaned, the support assembly being constructed and arranged to move the polymer film for cleaning, and at least one nozzle disposed adjacent the polymer film for providing CO2 to the polymer film for dislodging particulate matter from the polymer film and the at least one aperture, and for cleaning thereof.
