Abstract

An aq. dispersion of starch and an enzyme are gelatinised by live steam injection. The gelatinised soln. is hydrolysed in a conversion zone by holding for a while at a selected temp. After which the enzymes are de-activated to provide a starch paste. The conversion zone now takes the form of a long passage through which the soln. flows at constant temp. and in non-turbulent fashion at a constant speed throughout the length of the passage. Flow t hrough the conversion zone is pref. achieved by pumping the intial dispersion and/or recycled product, the latter to circulate incompletely converted fractions of dispersion. The final starch paste is a claimed product of homogeneous structure having starch molecules throughout which are of practically identical size. Used for mfg. a starch paste for use as a surface dressing prepn. for coating china clay paper and in textile industries. A continuous mfg. process producing a past of controllable, uniform characteristics.
