Pretty sure the mechanisms to do that are built into the fridge - a compressor, just like current refrigerators but using solids instead of gas.

  Hmmm, how do you pump a solid matter?

    You don't - you pump coolant around it to exchange heat.

    Anyhow, of course one doesn’t have to remove it from the fridge each time, and all the work is done by a mechanism.
