Complete tow dyeing project

GALVANIN S.p.A. produces complete tow dyeing project including:

LOADING SYSTEM OF DYEING CARRIER AND PRESS

Studied for the distribution of the tow inside the dyeing carrier placed in the press, it is composed of a retractable motorized trolley, where is installed an automatic loading arm. Together with the simultaneous rotation of the basket of the press, it places uniformly the material to be pressed in the dyeing carrier.

PADDER SYSTEM

To add chemicals before dryer.

DYEING MACHINE WITH BASKET

Vertical dyeing machines for tow with different capacities (from 5 kg to 1500 kg), complete with tanks for chemicals and dyestuff, air pad working function, differential pressure system, device for quick locking of the lid, external heat exchanger and sampling device. Machine can be supplied with preparation tank for the recuperation of the dyeing bath of the dyeing machine and for the preparation of the next dyeing cycle.

HOT AIR DRYER

It has a modular design for easier addition of supplementary chambers at a later stage to increase the capacity. It has a
special hot air circulation passing through the tow and the stainless steel perforated conveyor belt from top to bottom. Equipped with filter to guarantee removal of impurities and dust and automatic system to control the speed of the belt, air temperature and final residual humidity of the tow.

CENTRIFUGE

Hydroextracting machine suitable to accommodate one of dyeing material carrier with tow. The high rotation speeds ensure uniform extraction with minimal residual moisture and considerable reducing in drying times. It is equipped with a special device for drain of the water removing from the material during the phase of hydroextraction and a special inverter for recovery of energy during deceleration cycle allowing a big saving of energy cost.

UNLOADING SYSTEM

The unloading system takes the tow automatically from the conveyor belt of the dryer and brings the tow in the storage trolleys. The distribution of the tow in the trolley is uniform.

PRESS AND DISTRIBUTION DEVICE

Pneumatic press to remove the lid automatically and park the lid in a parking position until the complete unload of the dyed tow from the dyeing carrier. When the carrier is empty, the press puts automatically the lid on top the carrier back. The distribution device takes the tow from the dyeing carrier and brings it through a system of tube circuit that opens the tow before loading it in the conveyor belt of the dryer.
