For superior control over particle size when excessive fine crystals are present, the Swenson Draft Tube Baffle (DTB) crystallizer has been proven highly effective. This type of crystallizer is used primarily in the production of a variety of large-size crystalline materials such as Ammonium...

For special cases requiring very low operating temperatures achieved only by very high vacuum, and for those applications involving relatively small amounts of material, or when the material being processed must be handled on less than a continuous basis, it is often both convenient and economical...

Increasing energy costs have justified the increased use of mechanical recompression evaporators. The principle is simple. Vapor from an evaporator is compressed (with a positive-displacement, centrifugal or axial-flow compressor) to a higher pressure so that it can be condensed in the evaporator...

In a Forced Circulation Evaporator, liquor is pumped from the bottom cone of the vapor body through the tubes of the heat exchanger, where heat is added, and back into the vapor body where evaporation occurs. Sufficient liquid height (submergence) is maintained above the liquor inlet on the vapor...

For applications where high rates of evaporation are required, where there are scaling components, or when crystallization must be achieved in solutions with inverted solubility or relatively high viscosity, the Swenson Forced Circulation Crystallizer is the best choice. This type of unit, also...

For operation at temperatures below which it is not economically feasible to use vacuum equipment, or for solutions with very high boiling point elevations, the Surface Cooled Crystallizer is generally specified. The surface cooled unit is a type of forced circulation crystallizer consisting of a...

Swenson can supply direct contact barometric condensers when condensate recovery and cooling water quality are not issues. Swenson can supply the condenser directly mounted on top of the vapor body. A short piece of vertical pipe connects the vapor body with the condenser to minimize piping and...

The Swenson Steam Tube Dryer is a rotating cylinder containing rows of steam tubes, arranged in concentric circles, and extending the full length of the cylinder. The tubes are designed to transfer heat from the steam to the material being dried and may be supplied with or without fins, according...

When optimum heat transfer efficiency is required for the drying process, the Swenson Fluid Bed Dryer is the best choice. The fluid bed dryer features a stationary, upright shell, through which heated air is forced and/or induced by a blower arrangement. Material enters the system through a feed...

The Swenson Falling Film long tube vertical evaporator is preferred for heat sensitive liquors. A film of liquor flows down the inside of a tube and is circulated to maintain the required flow. Because of the circulating pumps on each effect maintaining the wetted tube surfaces these evaporators...
