  • 140 cubic feet compact steam-heated dryer
  • Two-door pass-through
  • One-way tilt
  • PLC controls

Recommended Capacity

300-450 lbs. Dry weight.

Basket

The basket shall have a volume of 140 cu. ft. and shall be constructed of 10 gauge perforated metal with 3 main and 3 secondary lifting ribs, supported by four 10” polyurethane rollers equipped with timken roller bearings and guided at each end by a total of four 5” polyurethane rollers equipped with timken roller bearings. All rollers shall be located outside of the sealed heating chamber.

Basket Doors

The basket doors shall be a minimum of 42” in diameter and shall seal to and rotate with the basket to prevent the possibility of damage to products being dried. They shall be operated by an air over oil mechanism for smooth opening and closing. There shall be two basket doors to provide for loading at one end and unloading at the opposite end of the basket.

Basket Drive

The basket shall be driven by v-belts around the circumference of the basket. There shall be a self-adjusting, constantly variable tension device to keep the belts properly tensioned. The belts shall be located outside of the sealed heating chamber.

Optional Basket Cleaning

If specified, there shall be a device to automatically keep basket perforations open and clear of plastic residue to insure efficiency of air movement.

Machine Tilt

The main housing shall tilt a minimum of 18º to facilitate fast and easy loading and unloading of the machine. The tilt mechanism shall consist of two 5” i.d. double-cushioned air cylinders.

Heat and Cool Down System

Heat shall be supplied by three steam/air heat exchanger coils utilizing cupro-nickel tubing and silver solder with an automatic cold air bypass. All necessary traps and valves shall be included (optional).

Heat Control

Heating and cool-down shall be PLC controlled.

Exhaust System

The exhaust blower shall be single inlet, dynamically balanced and belt-driven from a 15 hp motor to afford a minimum air flow of 9800 cfm. There shall be a device to automatically clean accumulated lint from the rotor at the beginning of each cycle.

Optional Outside Air Makeup

If specified, there shall be a means of providing makeup air directly to the burner and combustion chamber from outside the plant to prevent negative air pressure within the plant. The inlet duct shall have a minimum diameter of 26”.

Electric Motors

Exhaust blower 15 hp
Basket drive 5 hp

  • Automatic fire safety suppression system with alarm
  • Exhaust blower rotation sensor
  • Basket rotation sensor
  • Tilt interlock safety switches
  • Door safety switches
  • Guards on moving parts
  • Tilt and door warning bell
  • Electrical interlock to prevent door and tilt mis-operation
  • Door opens on power failure
  • Circuit breaker w/mechanical interlock to prevent opening of electrical panel with power on
  • Thermal overload protection devices for all motors
