Machine Usage:
● GHHG2800-3 three pass tensionless dryer is used for tubular fabrics and open width fabrics drying, suitable for cotton, blender and polyester.
● During drying, the fabrics are being supported by the net belts allthe time, upper and lower nozzles are blowering, the fabrics are moving in wave form, after several times vibrating and beating, the moisture will be evaporated, and the fabrics are dried gradually.
● During the whole drying process, the fabrics are in relax status, release the inside tension force fully, after preshinking and setting to reach the ideal results
● The machine has four heating method: Steam, oil, directly natural gas and indirectly natural gas. Please indiate before order.

Machine Configuration:

Infeeding mechanism assemble Overfeeding, net one, net two, net three and rubble belt, all controlled by independent inverters.
The nets adopts pneumatic tighten,relax automatically after stop the machine.
The net adopts pneumatic correct system, correct the path reliable.
The nozzles are made of hot zinc steel plate. CNC machining center made.
Drying chambers Each chamber two sets 11kw motor and two sets centrifugal impeller.
The motor is F grade insulated, and have oil injecting holes both in front and back sides. The motor equips high temperature resistant roller bearing; the impeller have high strength, high air pressure, the hot air circulation efficiency enhance 15-30%. The air motor impeller can be pull out together with the motor, no need to came inside to discharge, easy to maintain.
Three heating method:
Steam, thermal oil, directly natural gas and indirectly natural gas.
Steam heating: Pin type heat exchanger, Max temperature is 130℃.
Thermal oil heating: Pin type heatexchanger, Max temperature is  150℃.
Natural gas directly heating:Hankfuel gas burner, Max temperature is 150 ℃.
Natural gas indirectly heating: Hankfuel gas burner and stainless steel heat exchanger. Max. Temperatur130℃, Advantage: fabrics will not turn colour, disadvantage: natural gas higher consumption(about 15% more)
Each drying chamber equips filtering net; the filtering net is with 30mesh and made of stainless steel.
The machine frame is made of carbon steel square pipe8#. Inside we filled with temperature insulated material, reduce the loss of energy.
Equip insulated panel in four sides of drying chambers, the thickness of the panel is 105mm, we fill super alumina silicate heating resistant material, high temperature resistant silicon  rubber seal strip on insulated panels, so decrease the heat loss in maximum degree, so save energy in maximum.
Net belt is made of fiber glass and Teflonmaterial.
Each chamber equips one piece moisture exhaust pipe,air door inside and could adjust the air amount. Total moisture amount controlled by inverter blower.
Fabrics Exit Exit belt is one piece guide rubble ring belt.

Electrical system
● Electric controls adopts programme controlling method, equips blowers starting in sequence system, faulty fabrics protecting system, emergency cooling system, counter-clockwise system
● Electric components adopts Delta of Taiwan, Shneiderbrand low voltage appliance, Honeywell temperature controller.
