Hopper Dryer

Features

  1. It is possible to dry to a low moisture content since retention time is long.
  2. Homogeneous product quality is obtained because retention time remains sharp, and mass flow is retained.
  3. Switching of types of products is easy since perfect discharging is possible.
  4. Absence of internal moving parts makes maintenance easy.

Mechanism

Material - Product
The material under treatment, charged through the material inlet, fills the inside of the machine, falls by gravity flow, and is discharged through the product outlet.
Internal structure
The machine has a straight cylindrical shell, with the bottom part built in the shape of an inverted cone. An upper internal cone and insert cone are arranged at the upper part, and a bottom cone and lower insert cone at the lower part for the purpose of supplying hot blast in an evenly distributed manner.
The insert cone has functions to correct the mass flow disrupted by the internal cone and bottom cone.
