CRESCENT BLENDING SYSTEMS

Many blending systems used in frozen vegetable/fruit or nuts industries consist of several hopper feeders that operate volumetrically.  Using Magna Weigh Feeders for each product, multiple products may be blended in exact proportions, by weight.  The following picture shows ten products being blended.  The recipe of blend proportion may be sent via Ethernet network for percentage of each product.

SYSTEM FEATURES:

• Stainless Steel Construction
• Powder Coated Frame as option
• Balanced Design
• Natural Frequency or Standard Frequency Operation
• Next Generation Controls for Optimum Performance
• Sizes may be designed from micro feeders to very large feeders capable of feeding several tons per hour
• Custom designed for appropriate application

For Turf-Seed, Inc. we installed a large blending system for grass seed. The system handles eight different seed varieties stored in 30,000 lb. silos. Our electromagnetic feeders control the output from each of these silos based on recipes entered on a touch screen by the operator. A very efficient feedback system controls the displacement of each feeder. A signal from the displacement transducer on each vibratory feeder is converted to 0-10vdc, then compared with a set point. A PID loop controls the feeder controller to maintain the set point displacement for repetition and accuracy. Our total system design includes vibratory feeders, control panels, a motor control center and operator interface panel.
