Swamiraj Engineering has designed and developed cost effective system for
Pigment
drying which saves Energy & Valuable Time for drying the pigment, thereby
reducing the overall cost for drying.
In conventional Pigment drying system, the wet cake from Filter Press cake
is
first collected in Trolleys and then from trolleys it is fed into Trays.
These
Trays are then loaded in Tray Dryer. Depending upon moisture content these
Dryers will take any time from 24 Hrs to 40 Hours for Drying. To overcome
this
energy intense Pigment drying method, Swamiraj engineering has developed a
drying system with Noodling of Pigment. Depending upon moisture content the
material is dried between 6 to 10 Hours.
The New Pigment Drying system consists of the following equipment:
The Pigment Noodle Extruder Machine is used to make noodles from the wet cake received from the filter press through the Belt Conveyor. The working principle of the noodle extruder is wet cake getting pressed at a very high pressure in between an oscillating shaft & extruder plate, resulting in formation of noodles from the bottom of the extruder plate.
The oscillating shaft oscillates to and fro on the extruder plate powered by a hydraulic power pack to develop high pressure. The output noodles are collected in trays kept below the noodler. These trays are manually transferred to the Tray Dryer.
The Belt Conveyor is placed below the Filter Press Cake. The wet cake discharged from the filter press is collected on the Belt Conveyor. The Belt Conveyor then transfers the wet cake into the Noodle Making Machine.
A Tray Dryer is an enclosed insulated chamber in which trays are placed on top of each other in trolleys. Tray Dryers are extensively used for drying the pigment wet cake / pigment noodles.
The material to be dried (noodles) is placed in the trays. Heat transfer is by circulation of hot air by electric heaters or steam in radiator coils. Blower fans are installed inside to ensure proper circulation and transfer of heat. A control panel to control the temperature and other parameters is provided outside the dryer.
These dryers are available in SS304 from inside for all contact parts and externally in MS.
