About the Product

Why is Pellet Cooling Necessary?

The AMH series Counterflow Cooler is advanced equipment designed for efficient pellet cooling and cake after the pelleting process. This system ensures the optimal product temperature for storage and transport, while simultaneously improving pellet quality and durability.

❌ Problem: Hot Pellets After Pelleting

  • Temperature: 70-90°C
  • Moisture: 17-18%
  • Soft and prone to breakage
  • Prone to deformation
  • Not ready for packaging
  • Risky for storage (mould and moisture)

✓ Solution: Cooled Pellets

  • Temperature: Ambient + 3-5°C
  • Moisture: Below 12%
  • Hardness significantly improved
  • Stable and resistant
  • Ready for packaging
  • Safe for long-term storage
Operating Principle

Counterflow Cooling Process

1

Filling

Hot pellets (70–90°C) enter the hopper through the inlet rotary valve with airlock.

2

Distribution

The distributor spreads pellets evenly across the entire hopper area.

3

Counterflow Cooling

Cold air enters from below, moving upward through the pellet bed while pellets fall downward.

4

Process Control

Level and temperature sensors continuously monitor and control the cooling process.

5

Discharge

The driven grid discharges cooled pellets in a controlled manner through the outlet.

6

Discharge

Cooled pellets (ambient + 3–5°C) ready for packaging or storage.

Features

Technical Solutions

Counterflow System

Cold air moves counter to the pellets — prevents thermal shock and pellet cracking while maximising efficiency.

Level Sensors

Automatic control of the cooling process, moisture content monitoring and pellet bed regulation in the hopper.

Temperature Sensor

Real-time monitoring of cooler operation and control of the product outlet temperature.

Rotary Airlock

Proper material dosing, complete hopper sealing and uniform pellet distribution.

RS Type Grid

Various discharge modes — controlled, closed, final and emergency discharge.

Pneumatic Cleaning

Automatic grid cleaning system ensures uninterrupted operation and extends service life.

Stainless Steel

Cover, walls and critical components in stainless steel with cream RAL 1015 protective coating.

Inspekciona Vrata

Toughened glass with door switch allows easy access and inspection without stopping the process.
