The very accurate and easy to operate model PPS-5 semi-automatic scale has automatic tare, automatic feed and speed controls for both bulk and dribble feed rates, and automatic set points. The product flow from the hopper to the feed pan can also be controlled by an adjustable slide gate.
 
Example of Operation
To run a relatively free-flowing product into a l0 lb package, the product is loaded into the hopper, and the target weight is set at l0 lb. The package is placed on top of the scale, and the table is adjusted (up/ down) so that the funnel is inside the bag in order to keep the bag "standing" when empty. After starting the first fill cycle with the foot pedal, the controller will automatically switch into "learn mode" for the first cycle. During this time the controller tests the flow characteristics of the product and decides the best speeds and durations for bulk and dribble. The controller will automatically change the vibratory feed from bulk to dribble and stop the scale at l0 lb. The bag is removed and sealed. Each successive container is now filled by placing it under the funnel and depressing the foot pedal.
 
All product contact surfaces are stainless steel and easily disassembled. If needed, the scale and control panel can be removed from the table, and the table can be removed from the frame.
