To keep their meat fresh, Maple Leaf carefully regulates the temperature in all production areas of their massive facility.
In the Sliced Meat Room, a 13,000 ft2 refrigerated space, Maple Leaf employees slice and package huge volumes of meat every day. After each processing shift, cleaning personnel thoroughly steam clean the room, causing the temperature and humidity to spike.When the cleaning crew is done, the refrigeration system works hard to bring the temperature back down to a set point of 6°C in time for the next production shift.
In June, 2011, Barry Drake invited us to install an ecoair Rotation System® in the Sliced Meat Room to see if increased air circulation would have an impact on humidity levels. As Barry explained, “The goal was to cut down on my humidity because I have condensation issues on all the ammonia pipes. I have a 700,000+ ft2 facility that’s refrigerated. Condensation is a big issue.”
Our initial defined objective was to reduce relative humidity to 60% or less within the Sliced Meat Room.
What We Did
On June 22—just in time for the hot summer weather—we installed one of our EA-42 Rotation Systems in Maple Leaf’s refrigerated Sliced Meat Room. (Translation: We rolled the unit in and plugged it into the nearest wall socket. Our patented design is plug and play!)
We then programmed 12 Tinytag data loggers to take temperature and humidity measurements at 30-second intervals, and we placed them at floor, occupant, and ceiling levels throughout the Sliced Meat Room. Over a four-week period, we compiled temperature and humidity data with the ecoair Rotation System® running and switched off.
Finally, we charted data corresponding to peaks in temperature greater than the room set point (6⁰C) that required a minimum of 20 minutes cooling time to achieve and maintain a temperature of 6⁰C in the room for at least 20 minutes.
While we were unsuccessful in reducing the relative humidity to 60% in the Sliced Meat Room, our system did yield three valuable benefits for Maple Leaf:
- 1. Energy Savings
- With the ecoair Rotation System® running, we returned the room to its set point temperature almost 50% faster.“What we found out is normally it would take us an hour and a half to come back down in temperature after cleaning. [With ecoair] we could come down in 45 minutes,” said Barry, who was pleasantly surprised by this result.
