Model 140 GP Dryer Specifications
- 140 cu. ft. vol. Basket
- Compact Gas Heated
- Two-Door Pass-Through
- One-Way Tilt
- PLC Control
300-400 lbs. Dry Weight
The 140 cu. ft. basket frame is constructed of top quality 10-gauge steel with three main lifting ribs, three secondary lifting ribs, and six removable perforated panels for trouble-free maintenance. The basket is supported by four 10" polyurethane rollers and guided at both ends by four 5" polyurethane rollers. All CLM wheels are equipped with Timken roller bearings and located outside of the sealed heating chamber.
Consolidated's revolutionary basket door seals to and rotates with the basket to prevent damage to products being dried. The doors operate by an air over oil mechanism for smooth opening and closing, and are available with load door diameter options of 42" or 48" inches. Standard models include two basket doors providing for loading at one end and unloading at the opposite end of the basket.
The basket is driven by v-belts around the circumference of the basket. There is a self-adjusting, constantly variable tension device to keep the belts properly tensioned. The belts and basket drive are located outside of the sealed heating chamber and include an inverter for slower basket start-up and reversing.
The main housing tilts to 12º with a maximum of 18° facilitating fast and easy loading and unloading of the machine. The tilt mechanism contains two 5" ID double-cushioned air cylinders.
Lo-NOx Heat System
A high-efficiency burner is coupled to a full flame spectrum modulating system with fixed air to gas mixing for proper combustion before entering the drying chamber. The combustion chamber is constructed of a steel inner chamber with a steel outer jacket separated by a cooling space using the intake air as an insulator and to pre-heat the incoming air. Maximum firing rate of the burner shall be 2,500,000 btu/hr and average firing rate shall be 1,050,000 btu/hr at 26" wc pressure.
The flame modulation and temperature is PLC controlled and programmed to heat by inlet/outlet temperature, automatically or by time. Cool-down is also controlled by time or to programmed temperature.
The exhaust blower is single inlet, dynamically balanced and belt driven from a 15 hp motor to afford a maximum air flow of 9,800 cfm. Included is a device to automatically clean accumulated lint from the rotor at the beginning of each cycle.
Standard Outside Air Makeup
A means of providing makeup air directly to the burner and combustion chamber from the outside to prevent negative air pressure within the plant. The inlet duct has an inside diameter of 15" x 32.5".
Exhaust blower 15 hp
Basket drive 5 hp
Burner blower 2 hp

PLC Controls Shall Provide:
A. 10.4" Color Touchscreen HMI to program and control machine functions including but not limited to start/stop, reverse/non-reverse selection and recirculation time.
B. Detailed machine overview screen displays inlet/outlet temperatures, time, program number, faults, dryer cycle, excess exhaust back-pressure and other pertinent information.
C. 96 user programmable drying formulas with multi-level password protection to prevent operators from overriding management decisions.
D. Ability to customize dry/cool down processes by either time or inlet/outlet temperatures.
E. Ability to program the basket speed for each formula and to make a second speed adjustment near the end of the cycle to maintain the correct material drop.
F. Capable of transferring programs to other CLM dryers with PLC controls.
G. Control full-flame-spectrum modulation with 50:1 turndown ratio.
H. Lint trap controls with optional CLM lint collector.
Stainless Steel Dry Lint Collector Option:
If purchased, a stainless steel lint collector will be integrated with the dryer. Included with this option is an internal air receiver for end-of-cycle lint blowdown, and a separate dedicated fire suppression system with alarm. The transition from dryer to lint collector comes factory installed, and separate utility connections are not required. The 24" exhaust duct, to the atmosphere, is the only connection required. Lint shall automatically be removed into a lint bag or drum at the end of each cycle.
Interlocks, Safety Devices & Other Features Shall Consist Of:
- Automatic fire safety suppression system with alarm
- Exhaust blower rotation sensor
- Blower burner 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 malfunction
- Door opens on power failure
- Fireye flame protection device
- Automatic gas shutdown in case of increase or reduction in gas pressure (option).
- Circuit breaker w/mechanical interlock to prevent opening of electrical panel with power on
- Thermal overload protection devices for all motors
- Both hands required to close doors
- Manual fire suppression system switch with guard to prevent accidental activation
- Bell and light to indicate end of cycle
- Momentary basket jogging switch
