Bio-Industrial Opportunities: Dry Fractionation

Facilities & Equipment: Dry Fractionation

.
Dry fractionation is a process in which a raw material is separated into the many components that form the whole, original material. Materials are processed in a dried state and do not require the use of a solvent. Processing technologies associated with dry fractionation include, but are not limited to, milling, sieving and air classification.

	Hammer Mill (Mikro ACM) The characteristic feature is that grinding and classifying process happen synergistically. By adjusting both the speed of the classifier and the rotor, precise control can be maintained on the resultant particle size distribution.
	Wide-Chamber Pin Mill Enables ultra-fine grinding of difficult products. The large machine housing in comparison to the pin discs allows continuous milling of greasy, heat-sensitive and sticky materials without them clumping and depositing in the chamber. The speed and rotation direction of the pin disks can also be set at various parameters.

	Buhler Automatic (Flour) Mill MLU-202 Throughput: 10 - 12kg/hr
	Retsch Ultra Centrifugal Mill ZM 200 Feed material: soft, medium-hard, brittle, fibrous Size reduction principle: impact, shearing Material feed size: < 10 mm Final fineness: < 40 µm Capacity: 300 ml
	VirTis Freeze Dryer Can remove liquids from material without heat, which prevents potential damage from heat. Freeze drying involves the removal of water or other solvent from a frozen product through sublimation, a process directly from the solid state to the gaseous state without passing through the liquid phase. Freeze drying allows the preparation of a stable product that is easy to use and aesthetic in appearance. Properly freeze dried products do not need refrigeration and can be stored at ambient temperatures. VirTis Freeze Dryer features: 14 trays each 9.75" x 19.5" x 1.5" can handle food grade samples 50L condensing chamber can remove up to 2.5 L of alcohol or similar low boiling point substance programmable temperature profile sample or shelf controllable temperature can stopper samples under vacuum, if needed Click to view more Dry Fractionation equipment
