Dryers

Yarn Drying Systems

Three yarn drying systems are available to work with your Gaston County Package Dyeing Machine, or in a stand-alone mode. All incorporate heavy-duty, stainless steel construction to minimize maintenance and are easy to use, with standard features like the quick-locking kier lid. Coupled with a Gaston County controller, operation consists of loading the machine and touching a button.

The PERV (Pressure Extractor, Reverse Valve) Dryer provides efficient drying and extraction of moisture from dyed yarn. Our lowest cost dryer offers an economical balance between purchase price and operating cost.

The Avesta Dryer has been the industry workhorse since the mid-1960's, combining high speed and low operating cost for many yarn products.is one of industry's most efficient yarn dryers.

The HP-ST (High Pressure-Shell and Tube) Dryer Evolving from the proven technology of the traditional Avesta design, drying performance has been enhanced by the use of a high pressure blower, shell and tube heat exchanger, mist eliminator and modern control system.

PERV	Avesta	HP-ST	Feature
			Large pipes and full flow valves minimize system pressure and volume losses, permitting air flow directly to the yarn
			Quick opening and quick lock kier lids are standard
			Single or multiple kiers can be sized to use the same carriers as the dyeing equipment
			Kier Isolation valves may be installed on twin kier systems. Prevent overdrying of packages in the dry kier and direct air flow to the remaining kier for more efficient cycles
			Bypass valve is automatically controlled for blower anti-surge protection
			Air operated carrier hold-down is standard
			Hot air can be programmed to increase at a desired rate
			Static pressure is programmable and automatically controlled. It can be programmed to compensate for increased blower load as the drying progresses
			The condenser temperature setpoint can be programmed to change as drying progresses and the incoming air temperature rises, resulting in cooling water and steam savings
			Steam injection system for opening up warp beams
			Closed system prevents contamination of yarn and discharge of hot moist air into the environment
			Permits reclamation of energy used in drying in the form of clean hot water.
			Drying can be programmed either by achieving a pre-programmed differential between input and output air temperature with a preset time limit, or by time only
			The timed direction of air flow (inside/out, outside/in) can be programmed during all steps
			System sized for operation at 125 psi (862 kPa)
			Heaters and cooling coils are extra heavy duty fin type copper-nickel providing temperatures up to 300 degrees F (149 degrees C)
			Water separator and mist eliminator remove water from the air circulation system to improve efficiency and reduce drying time
			Maintenance-free shell, tube heater and condenser virtually eliminate downtime for cleaning
			High output blower (up to 400 hp) achieves the necessary air mass transfer for quick cycle times
			Offered in either vertical or horizontal motor configuration
			A programmable spray clean-out function is provided
