Mix low- and medium-density bulk materials fast and gently
The model MF-5-SS fluidized bed mixer gently mixes low- to medium-density bulk materials, including liquid additions, in times typically around 30 s. Mixing jobs vary from 10 s to 2 min. The machine employs two counter-rotating shafts turning paddle agitators rapidly within parallel U-shaped troughs. The flat, angular paddles with overlapping paths sweep material from the troughs toward the center and upward, causing it to become airborne in a “fluidized zone” above the longitudinal centerline of the mixing chamber, the company explains. Product degradation is said to be reduced by the shorter mixing times, and by the mixing action, which reduces shear. Liquids can be added in relatively high ratios while still maintaining the free-flowing characteristics of the batch. — Munson Machinery Co., Utica, N.Y.
