Final Product: Frozen Bagels
Project Scope:
Use Bin-(1) 350 Ft3 • Pressure Transfer to (5) Scale Vessels • Minor Ingredient Hand Dump, Transfer and
Storage • Minor Ingredient Automated Scaling and Transfer to (5) Receiving Vessels • Local Dust Collection
on Each Vessel • PLC Control with Local Graphic Operator RT Terminal Interfaced with Central Supervisory Computer
Materials Handled: Flour • Onion • Egg • Salt • Pea Flour
• Rye Flour • Wheat Gluten • Wheat Flour • Corn Flour
Solution Overview
Minor Ingredient Handling:
To assure scaling accuracy and repeatability, the ingredients are grouped into majors, minors, and micros. The
minor and micro ingredients are hand fed from bags and pressure conveyed to receiving vessels with individual
dust collectors, thereby eliminating cross-contamination. The volumetric feeders are calibrated to accurately
account for the different material specific weights and flow characteristics.
Automated Transfer System: Feeders automatically transfer ingredients
at variable rates to the (3) minor scales. A pressure system then transfers all minor ingredients to the
designated receiver located adjacent to the major flour scale. All minor ingredients are conveyed with
conditioned air to control the moisture and temperature of the materials.
Integrated System Control: The customer developed a specification to
guarantee commonality amount PLC's, format, screen configuration, and documentation. Each major equipment
supplier provided an electrical control system designed to operate their process. Our PLC receives recipe
and mixer designation from the customer supplied central supervisory computer. The software and logic then
schedule and execute the scaling and transfer of minor ingredients to coincide with the conveying and
scaling of the majors and liquids. All dry and liquid ingredient additions are integrated with the control
system supplied by the mixer manufacturer. Actual weighments are up-loaded to the supervisory system and a
running inventory is kept on all materials. An operator terminal was supplied to display equipment status,
alarms and batch information, utilizing color graphics.
