Production machine DD

For soaking, liming, tanning, retanning and colouring

The Dosemat DD - the superior machine for making leather. The hides are processed uniformly by the patented jet-cross-flow. No tears but effective and gentle action by the Y-Division.
The Dosemat's basic structure consists of 2 drums which are firmly connected with one another. Both rotate, while the entire width of the inner cylinder is perforated. The flow and transport chamber for the float is situated between the outer jacket and the inner cylinder. Intensive movement of the float is achieved by means of build-in diagonal stays and channels located in the front part. Via an oversize hollow axle, part of the float reaches a fixed mixing vat where it is available for measurements of all parameters and then flows rapidly back into the treatment chamber. Depending on the size of the drums, yields of between 700 and 2000 liters per minute are achieved.

Advantages

  • it works with less float than other drums
  • water and the chemicals are mixed faster
  • the float is immediatly spread over the width of the drum
  • the chemicals diffuse quickly into the leather
  • the float change is fast and controllable
  • temperature and pH are controllable
  • controllable water quantity = controllable chemical concentration
  • effective and gentle action without tears
