Box Temp

No.

 

No. When you set it at 32,33,34, it is trying to push air out at exactly that temperature. Rather than say it's a warm day and you put it at -10 it just goes as cold as possible until it gets there. It does that so it doesn't freeze the top layer like old units would. 35 is fine just remember any berries or leafy greens MUST run continuous. You can cheat a little with other commodities but never with berries especially.

 

Box temp=ambient temp in wagon--and only way to truly know--is to pulp...and I would be much more concerned w/berries(depending on what kind)if you were off to the low side--
and in constant run--you really need to watch unit for at least 10 minutes---especially once unti has reached setpoint--because it cycles between cool/heat constantly and will float couple of degrees in each direction
You'll be fine

 

Pulp the product first, especially berries and cherries. Do not accept a load that doesn't pulp within a degree or two of the set point.

Your reefer unit is not a blast chiller and will not cool a hot load in transit.

One exception is onions, potatoes and carrots, they are sometimes loaded hot, straight from the field and they'll want them run at 50° continuous.

 

Hey, just curious and interested in learning more about other segments of the industry than my own...

What do you mean when you say "pulp the load"?

Also, just wondering, why do berries need the unit to run continuious?

Thanks in advance for sharing!

 

Berries and leafy greens are very sensitive to temperatures outside their mostly 33-34 range. Even outside that a few degrees can shorten shelf life or damage the product. Other produce like apples onions potatoes lemons oranges etc. you can get away with a little more fluctuation since they are less sensitive to small variations in temperature. Every produce broker will tell you to run it continuous for whatever reason ...you learn as you go what you can get away with... Lots of it is common sense too. I did lots of apples and they are happy as long as they pulp between 33 and lower than 40. In summer can do start stop 33..winter start stop 37. Even in start stop if you set it at 33 or 34 it will try to blow the air out at exactly that temperature. It doesn't just blow in freezing cold air until box temp is happy. Old units did that, anything relatively new does not.

 

Reason you run continuous is because it it is easier on the unit. Anything above 10 degrees should be a continuous mode. Anything under 10 you're basically frozen load and a bigger gap in the times your unit would be kicking off and on. It wouldn't take as long to reach out of range then your unit would be kicking on then back off with a big fluctuation of temp. With continuous it cycles between cool/heat keeping a precise temp.
