Multi-Hopper Drying System Delivers Flexibility in Affordable Package

Conair hoppers
Conair’s Multi-Hopper Cart is suitable for basic use but also easily accommodates upgrades for advanced applications.

A global supplier of auxiliary equipment for plastics processors has introduced a portable multi-hopper resin-drying system that is simple enough for basic use while accommodating upgrades for advanced applications.

The Multi-Hopper Cart (MHC) from Conair features up to four dependable mass-flow hoppers mounted on a lightweight yet durable caster-mounted pushcart. The cart measures 35 inches deep, saving valuable floor space and making it easy to maneuver down narrow aisles and through doorways. Material can be dried off-line and wheeled to where it is needed, or the MHC can be stationed remotely to simultaneously supply material to multiple machines.

Seven different hopper sizes are available, ranging from 0.5-ft3 volume and a nominal capacity of 18 lb to 6 ft3 volume and 201-lb capacity. Image courtesy Conair.

Two basic configurations are available. The simplest has hoppers only with an insulated integral welded manifold system for supply and return of dehumidified air from a central dryer. It can also heat the material for smaller applications. For larger throughputs or applications that require higher temperatures, the cart can be wired for power with individual heaters added to each hopper. This allows several convenient features, including the ability to dry at different temperatures in each hopper, temperature setback to prevent over drying, and dewpoint monitoring and control. It can also be integrated into Conair’s SmartServices central monitoring and control platform, providing real-time alarm displays, a key performance indicator dashboard, machine view with real-time readouts of setpoint and actual temperatures, as well as condition indicator lights. The system can also display trend lines for key measurements in real time.

Seven different hopper sizes are available, ranging from 0.5-ft3 volume and a nominal capacity of 18 lb to 6 ft3 volume and 201-lb capacity. Carts are built in two sizes: A large version can accommodate up to four hoppers (depending on hopper size) and a smaller cart can be mounted with up to three hoppers (again, depending on size). A slide-gate discharge port prevents material leakage but facilitates easy hopper draining.

Available in carbon or stainless steel, all hoppers are fully insulated from top to bottom in order to preserve heat and save energy. All are designed for easy cleaning with a large clean-out door (with sight glass) and a removable air-diffuser cone. The mass-flow hopper design ensures that all material is evenly exposed to dry air and heat. Funnel flow and material hang ups are eliminated for superior drying. Each hopper is equipped with an isolation valve so that it can be taken off-line without disrupting operation of the other drying hoppers.
