Equipment for starch based glue production for corrugating machines (glue preparation for cardboards)

Its conception is based on common technologies for glue preparation in the system ”Steinhall”, ”No-carrier” or ”Minocar” w/wo viscosity measurement. The equipment is designed and delivered according to particular technological conditions on site and according to customer's specifications. Its delivery can include starch storage machinery, own equipment for glue preparation, dosing system for both powder and liquid borax, system of NaOH storage and dosing, storage tanks, delivery pumps and recirculation loops from the corrugating machine back to the storage tanks with pumps. As a part of optional accessories there is an external station available for other sorts of powder starch, so-called the ”Big-Bag” station including lifting and handling means, respectively a hopper for loading from paper bags. Starch conveying to the cooking tank is realised by means of a screw conveyer with electronic speed control through a frequency converter.
