Non tension dryer is used for tubular fabrics and open width fabrics drying, suitable for cotton, blender and polyester.

Five-layer three chambers tensionless pre-shrinking dryer
Machine Usage:
It 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 all the time, upper and lower nozzles are blower, 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 preshrinking and setting to reach the ideal results

Machine Drawing:

Technical Parameters:
Working width:1800-3800mm(price different)
Net speed:4-45m/min
Fabrics speed:4-60m/min
Overfeeding rate:0-30%
Drying chamber temperature: 100-150census.
Steam evaporation capacity:200-230kg/chamber/hour
Machine speed:3-45m/min
Total power:80.5Kw(3chambers)

Machine Characters:
1. The nozzles adopts Germany technology, upper nozzle will blow to seven directions. unique nozzle design, which could really realize the fabrics different position could be blowed from all sides, the fabrics move in wave shape, so the shrinking result will be the best. The shrinking rate could be 8%-10%.
2. The fan impeller adopts bolt to connect, could be disassemble completely, easy to maintain.
3. Alunium-steel composite fin pipe heat exchanger, which could raise temperature fastly,high efficient.
4. The air duct could be opened completely, very easy to clean the fibers inside of the nozzles.

Machine Mainly Structure:
TPYH series five-layer three chamber tensionless pre-shrinking dryer mainly consists of: flat feeding spread roller, tubular expanding mechanism, double over-feeding mechanism, high-efficiency drying chamber, fabric exit mechanical, moisture exhaust system, Electrical control and other system.

1.Flat feeding spread roller
The flat feeding spread roller is for open width fabrics,two sets roller totally, which could spreading the open width fabrics by spiral threads.(Optional)

2.Tubular expanding mechanism
The tubular expanding mechanism is used for tubular fabrics, The width can be adjusted freely.

3.Fabrics feeding mechanism
The fabrics feeding mechanism has belt tension mechanism,belt path correcting mechanism, fabrics infeed overfeeding mechanism, machine immergency stop deice .
Belt tension mechanism, The belt is tighten by the two ends roller, which is with screw. When the belt has deviation/drift, the belt will touch the limit switch with installed on the side of the belt, so the signal will be sent to the cylinder and action will be done.
Fabrics over feeding mechanism
Special design double overfeeding mechanism, which could make the fabrics has accurate overfeeding amount, form the natural wave inside the drying chamber. So the fabrics will be dried under the relax form. This mechanism drive by inverter motor, so could get the most reasonable overfeeding rate. The overfeeding mechanism speed could be adjusted by different type fabrics.
Emergency machine stop device
It is used for emergency occasion.

4.Drying chamber (include:machine entrance、middle chamber and tail of chamber)
Using four bolts to connect chambers. Using sealing strips to seal the space between two chambers. There is sucking tube in the top of the chamber. Each chamber has three parts: upper is air nozzles, lower is heating area, side is blowers area. In order to make the installation, maintainess and checking job easily, install gate on the side of the chamber. Each heating area and blower area are closed, so can control the chamber heating. Nozzles area are connected to other chambers.
Heating system
Every two chambers are controlled by pneumatic valve,which could control the hot air temperature inside of the chamber.
Hot air circulation blower
Each chamber has two blowers, which turn to opposite direction. There is sealing ring between drive shaft and chamber, protect hot air missing,there is coolant fan between sealing ring and motor, which could cool the bearing temperature. Under the same energy consumption,five layers dryer fabrics length(inside of the chambers) is 40% more than three layers dryer. The output could enhance nearly half.
Air nozzles
There are air nozzles inside the chambers,upper group and lower group. The nozzles adopts Germany technology, upper nozzle will blow to seven directions. unique nozzle design, which could really realize the fabrics different position could be blowed from all sides,the fabrics move in wave shape, so the shrinking result will be the best. The shrinking rate could be 8%-10%.
Filtering net
Between nozzle and heating system, there is one layer filtering net. It should be cleaned each day.

5.Fabrics exit mechanism
The fabrics exit mechanism mounted on the tail of the chamber, driven by belt.,plaiting mechanism and manual stop switch.
Belt drive mechanism
It is drive by inverter motor, speed is stepless.
Plaiting device.

6.Moisture exhaust system
This system consist of centrifugal blower driven by inverter, mounted on the roof of chamber, connect by air duct and machine. The moisture exhaust motor running could be controlled on the electric cabinet touch screen.
