What are the advantages of continuous mixing?

Continuous mixing can eliminate batch to batch variations and environmental concerns. It can also allow you to reduce your cycle times! A Readco processor is a versatile and flexible machine, which makes it a natural for pilot labs and today’s evolving manufacturing marketplace. Considering going from batch to continuous? Below is a batch versus continuous comparison check sheet. Would there be advantages for your process to go continuous?

CONCERN	BATCH	CONTINUOUS
Consistency of Product Quality	Batch to Batch Variations	Consistent Controls By Feeders & Pumps
Floor Space	Usually Large Area	Small Footprint
Total Mixing Time	Very Long 10 Minutes to Several Hours	Very Short Less than 1 Minute
Clean Up Labor	Intensive & Cumbersome	Very Quick, Clean In Place
Work In Process	Required	On Demand Production
Multi Stage Processes	Usually Single Step	Can Accommodate Many Processes
Utility Costs	Dependent on Motor Size & Mixing Time	Smaller Motor, Shorter Mixing Time
Environmental Issues	Usually Not Contained	Enclosed, Contained, & Controlled. No Cleanup Issues
Scrap Potential	Sizable Amount of Scrap	Small Amount of Scrap at Startup & Shut Down

Point Source Fume / Mist / Dust Control

PFP has design numerous central dust control systems and would like to introduce you to the concept of point source collection. The following represent many of the advantages of this concept.

• No ducting required for most applications
• Collected material is returned to product stream
• Building ventilation air remains balanced
• Low collector inlet velocities
• In event of fire or explosion, no link to other processes
• Expansion is just added with new process, not tied to existing systems
• Collection system is only on when process is in operation
• Lower fan horsepower
