Mixer Bowl Batching System Upgrade

A customer asked Sterling Systems & Controls, Inc. to analyze their existing batching system and do a mixer bowl batching system upgrade. This resulted in offering upgrades to reduce the manual handling of batches, eliminate equipment and increase production capacity. The original system to be modified was supplied by Sterling Systems & Controls in the mid 1990’s, old and well-used. An updated design was proposed to increase the batch size by ten (10) times to reduce the number of mixes for the customer. This also reduced the handling of the small mixer bowls and the associated conveyor equipment to move the bowls and the mixers. The new/upgraded system would also replace scaling equipment for both dry and liquid ingredients, including the scales and liquid meters. The batching control system was also updated to include formulation, inventory, lot tracking and data acquisition.

The customer in this situation had objectives for their mixer bowl batching system upgrade to also:

– reduce cleaning
– reduce maintenance
– have mixer bowl in a single location for batching
– create best configuration stack-up of equipment for optimal processing
– eliminate existing equipment stack-up
– have oil and starter metered directly into the mixer bowl rather than weighed and discharged
– include new water meter
– size scales for flour-based upon larger formula
– size scale for sugar-based upon larger formula
– salt and potato flake supply bins with low-level indicators, vibratory feeder, scale hopper w/ gate
– automation for flour and sugar pneumatic conveying systems (reuses existing equipment)

Process control considerations include:

– update PLC panel to Allen Bradley PLC and current technology of weight instruments
– upgrade four (4) weight instruments (flour, sugar, salt & potato flake)
– add a local control panel to the equipment frame with remote I/O; eliminate wiring
update PC to Windows 7 software
– all devices will be on Ethernet (PLC, PC, weight instrument, etc.)
– reuse existing motor starter panel; maintain hard wiring between PLC and motor starter panels
– airlocks will be on VFD’s
