A portable refrigeration and insulation unit includes a hollow cartridge with a sealed cavity and a top wall including a plurality of wells extending from the top wall. The wells are configured to receive and thermally treat food or beverage items, in particular slush beverage products, where each well is suitably contoured so as to contact a majority of outer surface area portions of a food or beverage item that is placed within the well. The cartridge cavity includes a heat transfer material that surrounds portions of the wells and facilitates heat transfer from food or beverage items placed within the wells to the heat transfer material during operation of the portable unit. The unit further includes an outer insulating case that receives the cartridge and provides additional insulation features. The cartridge is cooled to achieve a suitable temperature, is loaded with food or beverage items, and is placed within the case for use in a foodservice environment.
