Cold Storage Manager
Custodian of a half-million hundredweight of potatoes for nine months
The crop's worth more in March than it was in October — but only if you didn't cook it in November.
Runs a potato storage shed — typically 100k-500k cwt under one roof. Manages temperature pulldown after harvest, humidity, CO2 ventilation, sprout inhibitor application (CIPC historically, now mostly 1,4-DMN or essential oils as CIPC was phased out), pile inspection, and load-out coordination with processors and fresh packers. The shed is a living chemistry experiment for 6-9 months.
Heaviest concentration in Eastern Idaho (Bingham, Bonneville, Madison counties), Columbia Basin Washington, San Luis Valley Colorado, Red River Valley, central Wisconsin, and Aroostook County Maine. Often owned by growers as part of vertically integrated operations, or by storage cooperatives.
A hot spot in the pile no one caught until the smell hit. A humidifier failure during a cold snap that pressure-bruised the bottom layer. Regulatory uncertainty post-CIPC — the sprout inhibitor playbook is still settling. A processor calling for a load and finding the specific gravity drifted because storage held too warm.
Pulling a load in March that grades out the same as November intake. A clean CO2 reading after a tense first month of curing. Catching a soft spot via a pile probe before it became a hole in the pile.
Industrial Ventilation Inc. or Gellert ventilation controllers, Techmark or Sentinel pile monitoring sensors, propane or electric heat exchangers, ultrasonic humidifiers, 1,4SIGHT or Amplify (1,4-DMN) sprout control application equipment, paper pile maps annotated weekly, FSMA-compliant cleaning logs.
Frantic intake September-October (curing window), high-attention November-December (transition to long-term hold), steady January-April (load-out to processors and fresh pack), empty and getting sanitized May-August. The 'off-season' is when repairs and FSMA audits happen.
Career path
Often grown into from a grower or harvest-crew background — somebody who ran the pile during loading and stayed on through the winter. Some come from refrigeration trades (HVAC, industrial refrigeration) and learn the potato side. Ag mechanization or post-harvest handling coursework from a community college helps. Many shed managers are second-generation — dad ran the shed, kid runs it now.
Salaried, often with a storage-season bonus tied to shrink percentage and grade-out at load-out. Housing or a truck sometimes included if the shed is rural. Owner-operator sheds pay themselves on revenue minus utilities (which are not small — ventilation runs 24/7).
