i was considering the idea of constructing my own holding plate, and was wondering about design limitations.
Background: i own a '75 Allied Seawind
, which came with a seafrost engine-driven holding plate system. it works just dandy, but the ice box it's installed in lacks sufficient insulation
to keep things cold - without ice, the plate is thawed 3 hours after you charge it. i recently purchased a second plate here on CF, but it turns out i don't have enough wall space in the box to mount it.
weld up a stainless box that fits my ice box with lots of volume to it, fit it with copper coil, and fill it with brine.
sounds simple enough, right? so why is it every commercial
holding plate out there is around 3 inches thick?
I was contemplating making the plate thick, more like a block than a sheet. say a triangular section that sits in the bottom of the box, dimensioned 8-10" thick,
or curved back, conforming to the outer wall of my icebox
, leaving a straight, deep cavity for food
. Stood off the walls/floors for airflow, of course.
what say you all? Is there a good reason the prefab ones are 3" thick?
any other consideration?
anyone done it?
