CONVEYOR DRYERS

Our dryers come in four basic formats - and can be custom built to meet your dimension and drying needs.

  • Product enters and exits at opposite ends

  • Standard airflow is upward, downward airflow is optional for certain products

  • Models can be all, heat, all cool, or a combination of both

  • Optional airflow recycling (internally or externally)

  • Product depth of 2” to 12”

  • Highest air pressure is placed against wettest product at inlet end for best drying performance

  • Width 2’ to 8’ and Length 12’ to 50’ or more

SINGLE PASS DRYERS

TWO-PASS DRYERS

Two Pass Dryer

  • Multiple pass design increases air to product contact for improved efficiency

  • Product enters and exits at the same end of the system

  • Product is mixed as it drops into the proceeding pass for increased moisture uniformity

  • Standard airflow is upward

  • Models can be all heat, all cool, or a combination of heat and cool

  • Each convener is driven independently; product depth can be adjusted to compensate for product shrinkage, improve efficiency, and increases dwell time

  • Two pass design increases drying area without depleting floor space

  • Standard controls adjust airflow, product depth, dwell time, and air temperature

  • Product depth from 2” to 12”

  • Width 2’ to 8’ and Length 12’ to 50’ or more

Multi-Stage Custom Dryers

MULTI-STAGE DRYERS

  • Connect any amount of single-stage models together to create a custom multi-pass and multi-stage configuration

  • Connection can be made in-line, stacked or in parallel

  • Custom connection helps meet unusual or difficult floor spaces and layouts

  • Easy to upgrade the capacity and efficiency of any existing drying system by adding an additional model

Custom Negative Air Dryer and Coolers

NEGATIVE AIR DRYERS AND COOLERS

  • Single or multiple pass available

  • Fan (cyclone on air outlet side only, for negative airflow though entire system

  • Ambient air cooling and/or convection drying with steam heat exchanges

  • Airflow upward or optional downward airflow on top pass of two-pass designs

  • Lower height profile designs for reduced head space areas

  • Standard fines removal of bottom flat floor
