Method and system for thermoelectric cooling of products on display at retail

A thermoelectrically cooled system, the system comprising:

• a plurality of thermoelectrically cooled rods, the plurality of thermoelectrically cooled rods forming at least one rack configured to hold one or more cylindrical cans of a retail product, and wherein the thermoelectrically cooled rods having an outer member, an inner member, a thermoelectric element located between the outer member and the inner member, and at least one pair of electrical leads, which are attachable to the thermoelectrically cooled rods;
• and
• upon application of a source of electrical power to the pair of electrical leads heat moves through the thermoelectric element from the outer member to the inner member of each of the thermoelectrically cooled rods such that the outer member is cooled and the inner member is simultaneously heated.

A method of cooling a retail product, the method comprising:

• generating a heat flux between a first type of material and a second type of material to create a cold surface and a hot surface;
• and
• placing one or more cans of a moist smokeless tobacco product having a metal lid in communication with the cold surface to extend shelf life of the retail product.
