ColdPICK Tunnel



The ColdPICK M6 is a large postharvest pre-cooler designed to be on-site and accessible to multiple picking crews. Capable of rapidly pre-cooling up to six pallets of fresh produce continuously, a single ColdPICK M6 can process up to 6,000 lbs/hour. Though mobile, ColdPICK M6 are ideally kept stationary during a region’s picking season as their size necessitates relocation by a team of movers. M6 units can be cross-docked to additional units to increase capacity.

How It Works

  1. Produce is picked by the picking crew, then packaged and palletized.
  2. The pallets are manually loaded to the ColdPICK M6’s automated loading dock.
  3. Pallets are moved through the tunnel by conveyor so that picking crews can continuously load new pallets when ready.
  4. At the end of the M6, chilled pallets are conveyed to the discharge area and transferred to refrigerated trucks for direct shipment to the customer or distribution center.
