Description of Operation

  • Washing and Rinsing

The JENFAB  LJ 19-Inch Rotary Drum System continuously feeds parts through a rotating drum. As the parts are advanced through the drum, they pass into cleaning, rising, and drying sections. This design enables a large quantity of parts to be economically processed.

The parts are gently tumbled in the aqueous solutions. This gentle tumbling action provides a very effective method of completely exposing all edges, surfaces and blind holes to the immersion, high pressure spray, and high solution delivery cleaning action. JENFAB’S engineered immersion and spray system has greater cleaning capability and uses less energy than competitively-designed systems, resulting in lower energy consumption and a smaller footprint.

  • Drying – Recirculating Hot Air Super Dryer – Optional

The high-volume dryer forces heated air through the drum and parts to dry the parts quickly. After passing through the parts, the air is circulated back through the heating system and delivered back through the parts. This high volume of air flow in the re-circulating drying system dries parts at lower temperatures and in a shorter distance, lowering utility costs and saving floor space. Over 95 percent of the air is re-circulated in the JENFAB dryer, typically drying parts twice as fast while using more than half the energy of other systems.

  • Drum Drive

Jenfab’s 19 Inch Rotary Drum System is offered with an optional electronic variable speed drive. This will allow the drum to rotate from less than 1 RPM through a 3 RPM speed range.  This variable speed rotation allows for total flexibility of process capability, allowing excessively soiled components to be maintained in the wash and rinse zones for longer lengths of time

  • Lean Values—Removing Waste and Non-Value Added Time

The engineered drum, spray system and re-circulating dryer eliminate waste and non-value-added time from your manufacturing process while improving product quality and reducing energy and floor space requirements. Proper weld construction of the drum and helix, as well as proper helix spacing, vertically positioned headers, and a dryer design that does not use a snorkel tube, will eliminate potential for part mixing due to lodging, bridging, and part hang up.

  • Automation

Auto loading of parts is easily accomplished by incorporating feeding conveyors from forming or machining operations, by incorporating an optional vibratory feeder, a hopper feeder, or other means. Jenfab will work with you to automate loading and unloading of the proposed system.

The LJ Rotary Drum is compact, yet versatile.  Units can be placed in line for continuous feed operation or equipped with casters for mobility within a manufacturing area.

Advanced Features

Fifty years of experience and propriety design elements enable JENFAB to provide the best value in the industry. All JENFAB machines are designed and manufactured in the United States. The specified JENFAB power spray conveyor cleaning system includes these features that make it the most productive and easiest to maintain in the world:

Ø  Faster and Better Parts Cleaning— Vee Jet high-impact spray nozzles clean parts faster using less floor space.

Ø  Lower Maintenance Costs—Vertical, in-tank, maintenance-free, seal-less pumps.  Lift-off top panels enable instant access to spray headers.

Ø  Maximized Throughput—Drum Design and spray headers are engineered specifically to maximize throughput and cleaning effectiveness for your parts.

Ø  Long Service Life—Tanks and enclosure constructed with heavy-gauge 304 stainless steel and designed to provide a lifetime of trouble-free service.

Ø  Extends Cleaning Solution Life—Specially-designed stainless steel Baffles on the drum Exterior minimize solution drag over and contamination from tank to tank.

Ø  Ease of Installation—Single-point connections for water and electrical power simplify installation. Machine is built on heavy-duty structural base for shipping and installation in one piece.

Ø  Complete Draining of All Tanks—Sloped bottoms enable 100 percent draining for easy solution change-out and tank cleaning

Recirculating Hot Air Convection Super Dryer

 ( Optional )

 

This dryer uses the principle of high volume recirculating forced hot air.  A high volume blower forces air through the drum and through the part mass.  The air is continually captured, reheated, recirculated and directed back onto the parts again.  This high volume air flow recirculating through the parts and drum allows parts to be dried at lower temperatures and in less time, thus increasing the volume of parts that can be dried on a continual basis. This type of dryer can double the production throughput while reducing energy costs because the air is being used over and over and not being heated and dumped to atmosphere. Dryer Length is also 48 Inches
