Apparatus for making adhesive from starch, useful for making paper size, has starch boiler and circulating reactor with conical reaction zone formed by alternating teeth on stator and rotor for reaction with enzyme

摘要

In apparatus for making adhesives from starch, which has a starch boiler (10) in which a starch dispersion is subjected to steam treatment, equipment (40a, 40b, 40c) for adding enzyme and a reactor in which the enzyme acts on the starch, the reactor is a circulating reactor (26) with a stator (27) and rotor (28) forming a conical reaction zone (29) with alternating stationary and moving teeth (35, 36).
