Hopper Feed Conveyor Scale Controller

In service at a food processing plant, this operation has fresh product arriving in containers that are placed on a motorized conveyor. The containers travel along the conveyor, over a Weigh-Tronix conveyor scale where each is weighed and the time recorded. Finally the conveyor dumps each container's contents into a hopper, which feeds the fresh product into a blast freezer. To control the rate at which product is fed into the hopper a hydraulic gate is attached to the conveyor. It works by only allowing a single container to pass through at a time. The time between each gate opening is controlled by the WI-1310 scale indicator, which makes the decision of when to open the gate based on the desired throughput set by the operator, and the net weight that is passing over the scale. By making continuous adjustments in the timing of each gate opening, the hopper feed control system gets maximum efficiency from the blast freezer, without danger of overloading it and spoiling product.

Automated Tote Filler Controller   tote_fill

Designed to control the filling of containers with product pieces being moving along a motorized conveyor. A Weigh-Tronix scale indicator turns on and off 2-speed motors in response to the container's weight. Once a target weight and a dribble weight is set, the system fills at top-speed until the dribble weight is reached. Then filling continues at the slower speed, until it shuts off at precisely the target weight. This system is used is several mussel processing plants.  

Controller For Mixing Feed  tote_fill

A Weigh-Tronix scale indicator tracks and helps control the quantity of various ingredients and medicines that go into fish feed. In software a table of ingredients is created, and recipes for allowed feed mixes are defined that specify which ingredients to add and how much of each. When the operator selects the recipe he is stepped through each element to add to the batch, and the weight of each is verified and recorded for quality control purposes. A PC application stores the weights and time of each batch for production reporting .
