Dry vs Wet refrigeration?

[MacMac]

I can't remember how to create a dry refrigerator or wet refrigerator? Humidity? I didn't write down the technique because I thought I wouldn't forget.

Evaporator TD. More TD lowers humidity and less TD raises humidity.

Thanks, makes sense more colder means more water down the drain pipe.

Yeah the colder the coil is the lower the dew point of the air coming off the coil will be.

Knowing the refrigerated product determines the required storage conditions.This is for two conditions, RH% & temperature. A can of beer could care less about wet/dry WI box conditions. But ask a watermelon/lemons/limes/melons what conditions they demand for storage,dry. Then see what Lettice/strawberries,peaches would like,wet. Then check what conditions an "Aged Steak" MUST HAVE for WI box conditions. Clams require a dry shell so that the clam will clamp its shell shut to retain its inner water/moisture.

Flowers are the most demanding, I don't care what anyone says. Floral cases have to conserve as many drops of water as possible. Air velocity off the coil plays a significant role in dehydrating unpackaged products too.

Actually an overly wet beer box is a problem as well. If its bad enough the cardboard gets soaked, labels fall off bottles and the cheap glue on the packaging fetches loose. The problem is the customer projected a high turnover with lots of new product going in warm.

How true,how true! But covering my own butt,I did stipulate a can of beer.

Cans don't care, and that seems to be the trend. Maybe it won't be an issue any more.

Did a outdoor box here. Spring and Fall it had that problem. Installed a drain pan heater and humidistat for extra run time. Problem Solved.

How did the drain pan heater help?
How did you set up the humidistat?

Spring and fall it was cool outside so there wasn't enough run time. When the humidity was above 50% the heater ran with the refrigeration, longer cycles.
