Dried skimmed milk powder is automatically discharged from an in flight weigher 46 and blended with an adjunct such as whey, starch, vitamins or fat. The powder is conveyed to the in flight weigher which discharges a selected weight of powder to hopper 48 where adjunct material from feed hopper 50 is added. The powder and adjunct are then conveyed to mixers 56, 57, 58 and blended by augers 59. The blended powder is then passed through a sieve 64 and conveyed to a storage silo 68 prior to bagging. The weigher 46 comprises trap doors that are activated when a preselected quantity of powder weighs against them and close after discharge so that a fresh weighing cycle can commence. The weigher has an agitator 47 and the entire weight of milk powder discharged can be monitored by a central control unit. |
