Patent ID: 8616020

Claim:
A rail section comprising: a base pan configured to catch and drain defrosting ice and fluids; a top rail plate supported within the base pan; and a rail freezing and chilling mechanism coupled immediately under the top rail plate, the freezing and chilling mechanism being configured to create a, continuous layer of frost on top of the top rail plate from humidity of ambient air; wherein the top rail plate is made of a metal having a first thermal conductivity factor; and the rail freezing and chilling mechanism includes: a first non-metallic thermal layer immediately below the top rail plate; a metal thermal conductor layer made of a metal with a second thermal conductivity factor greater than the first conductivity factor below the first non-metallic thermal layer; a second non-metallic thermal layer below the metal thermal conductor layer; and at least one refrigerant line partially or fully embedded within the second non-metallic thermal layer, the at least one refrigerant line being configured to flow therethrough a refrigerant.
