HTHP Rapid Pressure Dryer
Product Description
Drying process: lift out the carrier from the dyeing machine and put into dryer. First, do the pressure dewatering in dryer, then the dryer uses the high pressure hot air for pressure dry, in the meantime, the high temperature high pressure hot air from the blower takes moisture out of the yarn, and the water is drained out from the condenser and air-water separator, the hot air cycles continuously until the moisture content of the yarn reaches the required rate.
Application
PED HTHP Dryer is suitable for package yarn, beam, loose fiber. The fiber is including cotton, polyester cotton, acrylic, wool, polyester, artificial fiber and blended.
Special features:
- Save a lot of work space
The traditional drying method has long technological process time and occupies large workshop site. The PED dryer only needs the space for loading and unloading the package yarn.
- High efficiency
Take PED-200(1000kg) package dryer for example, the dewatering and drying time of 1000kg pure cotton yarn need 90 minutes only, but the traditional drying method needs 5 hours.
- Low consumption
Take PED-200(1000kg) package dryer for example, the dewatering and drying process of 1000kg pure cotton yarn need 300 kw-h electricity only, in addition, the heat and electricity consumed in the PED rapid dryer are converted into 55°~75°clean hot water by the condenser which can be used for dyeing, but the traditional dryer needs 500 kw-h electricity and huge steam.
- High quality
PED Dryer is a high pressure sealed circulating dryer, which is not affected by external dust, temperature and humidity.
- Save a lot of labor
- Sealed circulating dryer
PED Dryer is a high pressure sealed circulating dryer, the temperature decreases with the drying process, the high- temperature air only comes into contact with the yarn when it's very humid. The moisture in the yarn evaporates to cool the yarn. In this way, the yarn physical properties protected and maintained.
Process
- Pressure dehydration
1) Take out the package carrier from the dyeing machine directly, put it into the dryer for pressure dewatering.
2) At the beginning of drying, fill in 5kg/cm2 compressed air to the main tank
3) During the pressure dewatering the heating and cooling unit are not running.
4)The high speed running fan passes the high pressure moist air from outside to inside through the package yarn.
5)When the moist air passes through the air-water separator, the moisture is automatically drained from the main tank and the air continues to circulate in the sealed main tank.
- Drying
1) When the pressure dewatering stage is completed, it enters the drying stage automatically immediately.
2) The heating and cooling unit automatically starts operating according to different yarn and fiber at set temperature during drying stage.
3) The high speed running fan passes the high pressure moist air from inside to outside through the package yarn.
4)When the moist passes through the air-water separator, the moisture is automatically drained from the main tank and the air continues to circulate in the sealed tank.
5) The heat and electricity consumed in drying step are converted into 55°~75° clean hot water by the condenser which can be used for dyeing.
6)Drying stage ends when the yarn incoming and outgoing wind temperature reaches set difference.
- Air circulation humidification
After the drying process, the heating device stops operating and the air flow penetrates from the outside to the inside of the yarn, thus balancing and reducing the yarn temperature.
At the end of the set process time, the compressed air is discharged from the main tank through a silencer and back to the normal pressure state, after which the carrier can be took out.
