What types of valve rotors are best suited to pet food processing?

There are a few good choices depending on your material. A standard V-shaped rotor does well in many cases, though we often specify U-shaped rotors to prevent material from packing in the creases — this makes cleaning and sanitation much easier. If you’re metering small batches, you might need a Reduced Volume Rotor or a Staggered Pocket Rotor to control the flow rate.
