The OptiFoil glass-lined agitator blade combines the advantages of hydrofoil agitator blades and trapezoidal agitator blades for improved mixing in glass-lined vessels, maximizing the pumping action required for homogenization, suspension, heat transfer, and crystallization of fragile particles. The blades can mix a minimum of 5 gallons in a 500-gallon vessel and 20 gallons in a 4,000-gallon vessel. The pitch angle of the blades also results in smoother contact with the product than vertically oriented trapezoidal blades as well as less shear. In addition, it prevents the alteration of fragile crystals. The blades can also mix higher viscosity liquids than can hydrofoil blades or standard flat blades, and they produce axial and radial flow characteristics that are suitable for virtually every process. Blades are available as an option on one-piece glass-lined mixers or as removable blades when used in conjunction with the company’s GlasLock interchangeable glass-lined agitator blade system. A range of sizes allows matching of the blades to the process and vessel capacity.
