This type of blender mixes materials into a liquid. Liquefiers dissolve and disperse virtually any food product efficiently and completely. Most liquefiers are rectangular, although some are round. Some round liquefiers have an arm that scrapes the insides, catching and returning product to the mix. The benefits of liquefiers include: dissolving soluble products in less than 5 minutes, complete hydration, total product liquefaction, elimination of solid "burn-on" in the vat, elimination of waste at strainers and tank bottoms and the complete dispersement of insoluble particles in water or non-aqueous media.
