Jacketed, Sanitary Rotary Batch Mixer Maintains Batch Temperatures

Jacketed Rotary Batch Mixer blends ingredients in parts as small as one per million with 100% uniformity in less than three minutes, while imparting minimal energy and maintaining material temperature levels.
 
Stainless steel mixing flights have continuous, polished welds with 0.25-in (6mm) radii, and are spaced for easy access and sanitizing.
 
UTICA, NY — A new Model 700-TH-20-SSJ, 20 cu. ft. (.6 cu. m) Sanitary, Jacketed Rotary Batch Mixer gently blends batches of ingredients in parts as small as one per million with 100% uniformity in less than three minutes, while keeping materials heated or cooled, says Charlie Divine, Marketing Manager of Munson Machinery.

The mixer can be piped to an in-plant chiller to prevent heat-sensitive bulk products from agglomerating, clumping, degrading, smearing and/or sticking to contact surfaces of mixing and packaging machinery or to the final consumer packaging, or to an in-plant steam, hot water or hot oil system to maintain elevated material temperatures during processing.

"The Rotary Batch Mixer has less effect on temperature levels of materials being blended than ribbon, plow or paddle blenders because it achieves total batch uniformity 10- to 20-times faster," says Divine, "so jacketed versions afford significantly greater protection against the gain or loss of heat than by any other means."

The USDA compliant unit reportedly evacuates 100% of the batch, and can be sanitized rapidly with no tools. Material contact surfaces are of 304 or 316 stainless, and the rotating drum has external, removable seals, while internal mixing flights are spaced for easy access and have polished welds with 0.25-inch (6mm) radii.

The unit is designed with a stationary inlet and discharge, and a rotating drum with proprietary mixing flights that tumble, turn and fold material gently while achieving 100 percent uniformity in two to three minutes, regardless of disparities in the bulk densities, particle sizes or flow characteristics of batch ingredients, according to the company.

Unlike stationary mixing vessels that leave a residual "heel" of material after discharge, the rotating vessel and internal flights of the rotary mixer are said to lift and direct the entire batch into the discharge spout for complete evacuation with no residual material or manual intervention, improving product quality and process control while facilitating rapid, thorough cleaning.

Models range in capacity from 10 to 600 cu. ft. (0.28 to 17 cu. m) and are equally effective in blending of batches that comprise between 5 to 100 percent of rated capacity, obviating multiple mixers in some cases.
