FLUIDISED BED MIXER ULTRA-FAST, GENTLE

A new 142-litre capacity Fluidised Bed Mixer model MF-5-SS from Munson Machinery, gently mixes low- to medium-density bulk materials, including liquid additions, in 10 seconds to two minutes, with 30 seconds typical.

Unlike ribbon, paddle and plow blenders with a single shaft turning agitator blades slowly within a U-shaped trough, this specialised machine has two counter-rotating shafts turning paddle agitators rapidly within two, parallel U-shaped troughs.

Flat, angular paddles with overlapping paths sweep material from the troughs toward the centre and upward, causing it to become airborne in a “fluidised zone” above the longitudinal centreline of the mixing chamber, where discreet particles of batch ingredients readily intersperse, regardless of disparities in particle size, shape or bulk density.

High- or low-viscosity liquids sprayed into the fluidised zone disperse readily throughout the batch, allowing liquids to be added in relatively high ratios while maintaining free-flowing characteristics of the batch.

The mixing action is said to minimise shear, which together with short mixing times, reduces product degradation.
According to the company, the mixer discharges rapidly through full-length, drop-bottom gates, and evacuates a greater percentage of material than conventional agitated machines, reducing the need to manually remove, and waste, residual material between product changeovers.
Recommended uses include mixing of low- to medium-density materials ≤800 kg/m3 ranging from powders to fragile flakes, with or without liquid additions, in applications requiring short cycle times and gentle product handling.

Other mixing and blending machinery offered by the company includes Rotary Batch Mixers, Ribbon/Paddle/Plow Blenders, Vee-Cone Blenders, Rotary Continuous Mixers and High Intensity Blenders. Size reduction equipment includes Screen Classifying Cutters, Pin Mills, Attrition Mills, Lump Breakers, Rotary Knife Cutters, Hammer Mills and Shredders.
