 Even, thorough, and rapid drying
Wyssmont TURBO-DRYER® delivers very uniformly dried product because material is intermittently redistributed with plug-flow operation. Uniform inside temperature or zoned temperature regions. The closest product temperature control of any dryer possible. Can give the lowest residual moisture of any dryer.
Product Quality
Gentle handling. Little dust, fines. Little product degradation, even with fragile materials such as crystals and pellets. Provides a free-flowing product when other dryers produce material that cakes or sets-up in containers, silos, or railcars.
- Handles temperatures up to 1200°F
- Precisely controlled temperature and residual time
- Easily adjusted and automatically maintained drying conditions
- Can adjust to varying feed rates
- Can operate with inert atmosphere recirculation with solvent recovery
- Operates as a dryer, cooler, reactor, heat treater, calciner, humidifier, agglomerator, sublimer, roaster, in combination if required.
- Environmentally sealed, and explosion-proof models
- The self-cleaning wiping action often eliminates the need for manual cleaning at product changeovers
- Easy startup and operation on different materials
- Low maintenance costs because of its unparalleled reliability
- Low energy costs. Low labor costs
- Can use any heating medium: steam, gas, electricity, oil, high temperature oil or waste gas from other operations
- Does low temperature drying as low as 60°F without vacuum or up to 1200°F
- Available in laboratory sizes, package units, and large field erected sizes
- Manufactured in a wide range of materials
- Vertical construction, little space requirements. Outdoor or indoor installations
- Accurate scale-up from tests on a few pounds

| The product needs to meet USP 99 and be of food grade to meet FDA and U.S. and Canadian health and food standards. After drying, we will press into large tablets then package in small plastic containers normally used in health food (supplement) sales. If you have a white paper, please email it to me. At first we need the smallest unit you have -- almost lab bench size or be able to rent a unit or outsource the initial production from our pilot plant. Our goal is to process 10 million gallons of algal oil per year which will produce about 10 or more million gallons of wet cells. We have a choice of processing the wet cells into animal feed (dry or wet), using it as a feedstock for fermentation, possibly using it as feedstock for enzymatic catalysis into ethanol when the science and engineering so allows, or drying it for the health food market, which is probably the most viable choice at this time.
