Precise Temperature and Moisture ControlSolex dryer/conditioner technology enables both moisture content and the temperature

of the final product to be independently and precisely controlled. The combination of the

two media - indirect heat and cross-flow air - enables accurate control over the desired outcomes. The

indirect method of heating regulates the final product temperature; at the same time, the amount of

cross-flow air used regulates the final product moisture content.

Ultra-Efficient Technology with 90%+ EfficienciesThe indirect method of heating the product serves to heat the product and maintain the temperature

of the cross-flow air. Since the temperature of the cross-flow air does not drop, the air maintains its

moisture carrying capacity and is capable of carrying larger quantities of moisture. As a result, only

a very small amount of cross-flow air is needed to remove moisture from the product. The result is

efficiencies of greater than 90%.

APPLICATIONS APPLICATIONS

COOLING & HEATING FERTILIZER

Efficiently Cool Fertilizer Without Caking

The problemFertilizers are hygroscopic, containing a low percentage of water. As they cool, this water

will transfer to the air in the void space which can lead to condensation and caking.

The Solex SolutionSolex has developed advanced modeling based on the critical relative humidity and the drying characteristic of each type and grade

of fertilizer. Caking is prevented by ensuring that the water temperature is above the dew point of the air in the void space between

the prills or granules. In the Solex Fertilizer Cooler, the water temperatures and purge air requirements are carefully selected to

provide optimum cooling performance without the risk of caking.

The Result The Solex heat exchanger cools fertilizers reliably without condensation or product caking.

Lab Testing

The Solex lab testing facility provides its clients with extensive analysis of bulk solids materials to help evaluate physical and thermal properties of the bulk material, as well as determine material flow characteristics.

Lab Testing Consists of the Following Procedures:

Material Property AnalysisMaterial characteristics of the product sample are tested to

determine particle size distribution, bulk density, moisture

content and angle of repose.

Flowability TestingFlowability testing determines the optimum heat exchanger

plate spacing.

Mass FlowMass flow testing (shear cell testing) is carried out to determine

material flow characteristics to ensure that mass flow (uniform

velocity) is obtained in the equipment.

Thermal Property AnalysisThermal Conductivity testing is performed to provide the

measure of how well a material conducts heat. Solex measures

this in its lab using an advanced hot wire method.

Solex performs advanced theoretical modeling to predict the thermal performance of the proposed equipment, and validates this modeling with pilot testing under true process conditions. The result is guaranteed thermal performance.

Theoretical ModelingThermaPro, the proprietary thermal

modeling software developed by

Solex, enables precise theoretical

modeling. ThermaPro accurately

predicts product temperature profiles

of the bulk solids materials at each point

through the heat exchanger providing

100% accurate predictions of final


Pilot TestingPilot testing is performed with test units that closely

duplicate full size equipment. The on-site testing can

help analyze and validate the following:

» Equipment thermal performance.

» Product flowability under true process conditions.

» Heat exchanger performance over an extended

time period.

» Successful operation through typical plant cycles

including possible upsets.

» Successful operation with a specific product mix.

What Makes Solex Technology So Efficient?

Traditional Cooling Technology Requires High Energy ConsumptionThe most common method of cooling bulk solids is direct air-cooling – like fluid bed

coolers or drum coolers. With this method, large horsepower fans take in

and blow ambient air across the product. The air is then discharged through

an air cleaning system to an exhaust stack. The inherent problem with using

air to directly cool bulk solids is the signif icant quantity of air required

and the expense involved in chil l ing, processing and cleaning that air.

Solex Cooling Technology Requires Minimal EnergyThe Solex technology cools bulk solids indirectly using water. With this technology,

cooling water is pumped through a vertical bank of hollow stainless steel plates while

the bulk solid passes between the plates at a rate sufficient to achieve the required

cooling. No air is required in the cooling process and the energy requirements are

minimized. The total energy consumption of the Solex heat exchanger can be 90%

less than air-cooling methods.

50 tph Facility

The energy consumption of the Solex cooler is 0.3 kWh/tonne vs 7 kWh/tonne for a typical fluid bed cooler.

The total electrical energy savings over five years is approximately USD $750,000.
