Mixing equipment especially for manufacturing starch adhesive

摘要

A starch based adhesive is made in an agitator tank which has a first rotatable propeller shaft with a plurality of propellers distributed along the length thereof. Each of at least some of the propellers is surrounded by an apertured shroud, which could be made of expanded metal or the like, for example. Above the propeller shaft is a second rotatable shaft having a plurality of high speed shearing blades affixed thereon. The two shafts are preferably driven by separate motors, the shearing blades being driven by a motor having approximately 4-5 times the power of the motor driving the propeller shaft in order to impart a comparably larger amount of energy to the slurry via the shearing blades as compared to the energy imparted by the propellers.
