Internal Draining Roller

Salient features and advantages:

By replacing your regular rollers with internal draining rollers, you can;

Ø      Improve feeding

Ø      Eliminate re-absorption

Ø      Lower bagasse moisture

Ø      Improve boiler efficiency

Ø      Increase mill extraction

Ø      Increase mill capacity

Drainage is facilitated by 12 to 16 horizontal holes connected through a number of nozzles provided in the groove root. When bagasse is compressed by the rollers (in two nips) the pressure in the zone is very high which resultantly forces the expressed juice out through the nozzle and the horizontal drainage system which exit in the special juice rings provided.

Our Internal Draining Roller is designed to take due care to increase the material strength at vulnerable areas by casting the shell with special material tubes (for horizontal drainage) which increases the strength by the chilling action and provides a smooth surface which prevents build up of bagasse in this area. Due care is taken in selecting the correct shrinking tolerance, temperature control during shrinking and selection of pitch for drainage.

The roller efficiently drains juice extracted from all three nips, with almost 40% of the nozzles fed under pressure. This eliminates flooding and minimizes re-absorption. Approximately 15% of the total amount of juice removed here reduces the weight of the material to be handled by the mill.   Compared to conventional milling, moisture is further reduced by 10% for the first mill and about 4% for the last mill with reduction in Pol in bagasse.
