This drum adopts isolating pump heat circulation technology and is effective in transmitting heat into drum by heating the media in the inter-bed which prevents the leather against contamination by separating the water from getting in touch with the leather liquid and ensures thorough discharge of water without residue.It works well in heating and temperature-keeping no matter with or without water in drum,even the drum stops.It is possible to make choice between the electrical heating and steam heating modes,even the double supply of both steam and electricity is feasible while it is adjustable to control the temperature at the range from the normal temperature up to 80℃ with the precision at ±1℃,which could meet the demand for various processing needs.

We adopt intelligent controller or PLC touch screen together with frequency conversion function to make it possible for automatic rotation in positive and reverse direction,intermittent shutdown,single-direction rotation,forward/backward inching operation and so on.
