The Komline-Sanderson Paddle Dryer / Processor are highly efficient, mechanically agitated, indirect heat transfer devices that add or remove heat from a process mass. They are used for drying, heating, cooling, pasteurization, crystallizing, and reacting of pastes, cakes, powders, and granules.

Dual counter-rotating shafts with unique intermeshing wedge shape paddles produce intimate mixing and optimize heat transfer. The use of hollow paddles for heat transfer results in a compact machine. The heat transfer medium: steam, oil, thermal fluid, water, or glycol is isolated from the process mass.

Komline-Sanderson offers vapor tight designs for applications with volatile organic compounds (VOCs) or hazardous materials. Temperature sensitive materials can be dried at low temperatures under vacuum.

Applications
Drying
The K-S Paddle Dryer is indirectly heated with steam or thermal fluid (hot oil). This provides for high energy efficiencies and low off-gas volumes. Heat transfer mediums of up to 750 °F can be used. Hot sweep gas can be employed to prevent condensation in the vapor space or downstream of the dryer.

Drying to low moistures or residual solvents levels of 10 ppm or lower requires uniform heating and residence time. The K-S Paddle Dryer allows you to reach these objectives with a continuous process.

The K-S Paddle Dryer provides a reliable and efficient method for drying slurry, filter cakes and centrifuge concentrates. Vacuum designs can remove water or organic solvents at reduced temperatures.

Heating
Heating a process mass for melting, cooking, pasteurization, roasting or reacting. The heating medium can be steam, hot oil, or hot water. Two- zone design allows for two distinct temperature zones.

Cooling
Remove heat from a process mass with cold water or thermal fluid (glycol, down to -40 °F). Cooling can be done in a controlled moisture-free environment. Two- zone design allows for two distinct temperature zones.

Calcining
Hot oil can be used for calcining at temperatures up to 700 °F. Evaporation of water prior to high temperature calcining will increase the capacity of the high temperature equipment, and the thermal efficiency of the process.

Reacting
Precise temperature and residence time control allows the K-S Paddle Processor to be used for catalyzing and controlling reactions. It can be used for both exothermic and endothermic reactions. A high degree of mixing allows multiple ingredients to be thoroughly mixed as part of the reacting process.

Crystallizing
Selective polymer crystallization or crystallizing at controlled rates and temperature can be achieved by using the K-S Paddle Processor.

Materials processed include:
Chemical: salts, catalyst, brominated organics, cellulose, starch
Petrochemical: solids devolatization
Polymer and plastic: polypropylene, polycarbonate, polyphenylsulfide, PET, PTA
Food: flour, beverage powders, confectionary ingredients, meat products
Mineral and metal: metal powders, metal carbonates, sulfates and hydroxides

The Komline-Sanderson Paddle Dryer / Processor are a highly efficient, mechanically agitated, indirect heat transfer devices for adding or removing heat from a process mass. Dual counter-rotating shafts with unique intermeshing wedge-shaped paddles produce intimate mixing, uniform heat transfer, a high heat transfer rate, and a self-cleaning effect. No stator bars (breaker bars) are needed.

A large heat transfer area to volume ratio is achieved by the use of hollow paddles and a jacketed vessel, through which the heating medium flows. The result is a compact machine with less space requirements and lower installation cost.

A metal wall separates the process mass from the heat transfer medium. High thermal efficiency is obtained because the heat transfer is by conduction. Very little heat is lost with an insulated dryer.

The K-S Paddle Dryer transports material, regardless of its handling characteristics. Sticky, pasty materials can be transported. Pre-conditioning the feed by mixing with recycled dried product, to make it conveyable, is not required. This results in lower capital, operating, and maintenance cost.

Material is conveyed through the K-S Paddle Dryer by displacement (“piston flow”). As material is added to the feed end, it is assimilated into the bed by the mixing action of the agitators. Hydraulic head pressure, combined with the action of the wedge-shaped paddles, pushes material around and through the paddles. Since the product moves by displacement, residence time is controlled by the feed rate and the overflow weir height.

The K-S Paddle Dryer is designed with high torque capabilities to increase its process flexibility. Extra torque keeps you on-line, when upset conditions develop.

Because the K-S Paddle Dryer is indirectly heated the amount of off-gas is minimal. Typically no external sweep gas is required. For certain applications sweep gas is used to increase the drying rate or to prevent condensation in a cooler or the vapor outlet of a dryer. Heat tracing the cover can also be done to prevent condensation from occurring.

System
K-S process and project engineers provide assistance at all phases of the project. Depending on your specific requirements, K-S can provide you with a dryer/processor, or a complete system.

A successful plant depends on the integration of the key process units with properly selected ancillary equipment and the right facility design. Reliability, ease of operation, rugged construction, performance, and the superior customer service are all trademarks of a K-S installation.

A typical system includes a feed metering device such as a variable speed conveyor or pump. Feed metering is an important part of process control.

In most applications the off-gas volume is very low and at a low temperature. When sweep gas is used, K-S can integrate sweep air conditioning into the system.

Safety features must be part of the system design. The K-S Paddle Dryer operates with an inert low temperature environment. Air is not used to convey a hot product in the dryer. Off-gas can be recycled after volatiles are condensed.

When necessary, explosion suppression systems or deflagration vent panels are incorporated into the dryer’s cover. Inerting of the process with nitrogen can also be accomplished with a minimal purge rate.

Our vapor tight design allows for the processing of material containing organic solvents and hazardous materials in an enclosed safe manner. Heat sensitive materials can also be dried at low temperatures under vacuum using hot water as the heating medium.

FAQs
How efficient is the K-S Paddle Dryer?
An indirectly heated, well insulated, Paddle Dryer / Processor has a thermal efficiency of approximately 98%.

How much energy is needed for drying?
The amount of energy required for the K-S Paddle Dryer is dependent on the initial moisture and the final moisture as well as the feed and discharge temperatures.

Example: Our dryer needs 1155 BTU per pound of water removed to dry material from 20% ds to 90% ds. This is the “heat load” at the dryer. To calculate the fuel cost, you need to factor in loses at the boiler or thermal fluid heater and line loses. For example, a steam boiler is typically 80% efficient while a thermal fluid heater’s efficiency ranges from 83% to 87% depending on design.

How is the dryer/processor sized?
The hourly feed rate is established and from this the total heat load (Q) is determined. The heating/cooling medium temperature establishes the log mean temperature differential (driving force, LMTD). The heat transfer coefficient (U) is dependent on the material being processed. This is established by using data from prior experience and test data. With these values established the heat transfer area (A) is calculated by:

A = Q/(U x LMTD)

What steam pressure is required? What thermal fluid temperature is used?
For drying of most materials, a heating medium temperature of 380 to 400 °F is used. For heat sensitive materials, much lower temperatures are used. For drying of inert materials much higher heating medium temperatures can be used (up to 750 °F).

Does K-S offer lab and pilot test?
Yes, K-S can provide pilot testing at our Technical Center or at your plant. Information on our test programs is provided in “References”.
