Cold Chain Basics

Set points vs. pulp temperature

The reefer set point is the target air temperature. Pulp temperature is the internal product temperature. Both matter: a cold trailer with warm product still risks quality loss.

Pre-cool before load

Trailers should reach set point before product enters. Loading into a warm unit pulls heat from product and extends pull-down time in transit.

Transit risk factors

Door openings, long dock waits, incorrect set points, and mixed loads with incompatible commodities are common causes of excursions.

Documentation

Keep pickup and delivery records, temperature summaries, and exception notes aligned with your FSMA and buyer audit requirements.
