TNL TECNAL´s Dryer/Cooler can be used for expanded meat or meal. Equipped with drive and driven head structured in closed profiles made of carbon steel and closed with stainless steel plates. Shaft made of steel SAE 1045 mounted on thrust bearings FAG/SKF with keyed sprockets made of nodular cast iron. Bearing houses sealed with felt rings against dust leakage. It has frontal inspection doors with quick clamp that allows accessing the inner part of the equipment, sealed with felt joint against dust leakage. Chain stretching by bolts, for the driven head.

Feeding is done by a fix feeding hopper made of stainless steel that performs the distribution of the material over the grate-type bottom, avoiding air escaping and providing excellent performance of the equipment.

The automation system is comprised of a level transmitter, installed in the feeding hopper and connected to a controller and a frequency inverter that works directly on the drive motor of the set of chains, which synchronizes the dragging speed according to the material flow in the hopper, keeping a constant layer height of material during the entire process. This synchronization also ensures a perfect material seal, which avoids the air inlet or outlet through the drive/driven heads.


  • Perforated fix screen made of stainless steel;
  • Feeding with uniform distribution;
  • Constant and uniform height of material layer.


Capacities: 100 to 6,000 tpd
