Abstract
A system for handling a multitude of particulate solid minor ingredients to be selectively added to individual batches in a batch treatment blending process comprises storage vessels, inventory control methods, recipe correction methods, a batch weighing system and weighing trolley for feed to one of a series of blenders. The system's mechanical components are under fully automated control by a computer, using bar code scanners. Inventory control is accomplished by providing dedicated storage vessels and a weighing system whose output signals are monitored by the computer. The functions of batch weighing and batch delivery for particulate solids employ a number of carriers which serve as dedicated delivery containers. Each carrier is carried on a trolley rail system and the trolley moves the carrier to various nests of solids storage vessels for weigh-in filling of the minor ingredients by screw type feeders, as directed by the computer, and based on the computer-stored recipe information. Each filled carrier is then carried by trolley to deliver its weighed contents to its preselected blender. For efficient high-volume operation, the carriers can be transferred to and from storage…
