Mk 8 Dry Mixer Superior to V Blenders, Cone Blenders, Company Says

The Rollo-Mixer Mk 8 rotary batch mixer is touted by its company, Continental Products Corp. (Osseo, WI), as a mixer superior in uniformity, cleanout, and overall efficiency compared to other mixers typically used in the dietary supplement and contract manufacturing industries.

The Mk 8 batch mixer uniformly blends dry particulates in 3 to 5 minutes. Like all Rollo-Mixers, the Mk 8 batch mixer creates rivers of material that gently divide and combine in the batch several times per revolution, resulting in a quick, gentle, and homogenous blend, the company says. The machine also allows the entire batch to empty completely within seconds.

Small-volume additions of vitamin additives are made easy using the technology, the firm says. “We blend batches with 80 ingredients where we can uniformly add 10 international units of a vitamin into hundreds of pounds,” the company quotes a customer as saying in a video. “V and cone blenders can’t do this, and ribbon mixers definitely can’t do this.”

The mixer was also designed with no mechanical drum seals in order to provide superior cleanout capability. The company says that easy cleanout and access are critical in food, specialty products, and high-purity batch-mixing applications. The Mk 8 machines can be rinsed and dried in 15 minutes, ready for the next batch.

The Mk 8 is one of five versions of the Rollo-Mixer line, which includes the Rollo-Mixer Mk VI Batch Mixer, the Mk VII Rotary Drum Mixer, the Mk VII-1 Rotary Drum Blender, the Mk VIII Powder Mixer, and the new Mk IX Batch Coater. 

Rollo-Mixers are designed and built to customers’ specific batch, blending, or coating applications. The Continental Rollo-Mixer is a rotary drum batch blender that uniformly blends ingredients having a wide variance in particle size, density, and proportions, typically in only 6 to 9 revolutions. Product moves by gravity in all planes. The gentle, low-shear, fast-mixing, positive displacement action creates continuous rivers of material, which course into and flow through one another in a random confluence.
