Abstract
Abstract AN AGGLOMERATOR FOR AGGLOMERATING FINE PARTICLES OF MATTER SUCH AS WATER WETTABLE FOOD PARTICLES AND/OR FOOD ADDITIVES, INCLUDING AN AGGLOMERATION CHAMBER HAVING A GREATER CROSS-SECTIONAL AREA IN ITS UPPER PORTION THAN IN ITS LOWER PORTION AND HAVING ADJUSTABLY MOVABLE WALLS FOR CONTROLLING THE SIZE OF THE AGGLOMERATED PRODUCT. MATERIAL TO BE AGGLOMERATED IS SUPPLIED TO AN ENTRANCE ZONE AT THE BASE OF THE CHAMBER WHERE IT IS WETTED AND THEN SUSPENDED IN A GASEOUS (AIR) MEDIUM IN THE CHAMBER. AN ADJUSTABLE BAFFLE AT THE ENTRANCE ZONE CONTROLS THE FLOW OF THE WETTING OR ACTIVE AGGLOMERATING AGENT AND THE GASEOUS MEDIUM. THE PARTICLES ARE CAUSED TO AGGLOMERATE TO A SIZE SUFFICIENT TO OVERCOME THE BUOYANT FORCE OF THE GASEOUS MEDIUM FLOWING THROUGH THE CHAMBER AND THEN TO BE DISCHARGED THEREFROM ADJACENT THE ENTRANCE ZONE, WHILE THE GASEOUS MEDIUM LEAVES THE CHAMBER THROUGH AN EXHAUST ZONE AT THE UPPER PORTION OF THE CHAMBER.
