A device for thermally treating products, especially food and beverages, is provided with a thermal element improved in its heat-exchanging efficiency, which is brought into surface contact with the goods to be treated and the selection of a thermal medium suited to establish any desired temperature of the goods and can be charged into the thermal element. For this purpose, the heat-exchanger wall of the thermal element is built in wall sections in order to form a closed unit with the goods to be treated and the thermal element is kept in mutual surface contact and the remaining wall portions form together with the heat-exchanger wall a tightly closable container for the thermal medium having at least one filling and discharge opening, provided with an openable closing element for the thermal medium. The thermal element can be built with basically rigid walls, comprising wall portions fitting the shape of the goods to be treated. However, it is also possible to build the thermal element with flexible walls, whereby it can be adjusted to the shape of each product to be treated.
A device for the thermal treatment of products, especially food and beverages, comprising a container for holding a thermal medium, said container defining a thermal element having walls which are at least partially formed as heat conductive walls, said heat conductive walls being formed in sections having a shape complementry to the product to be treated for maximum heat exchange when one of said sections and said product are brought into mutual surface contact, said container being formed with at least one filling and discharge opening provided with an opening and closing element for said thermal medium, the sections of said thermal element being rigid, with at least one section being formed as a concave segment of a cylinder, said concave segment having a frontal edge thereof formed with a recess for receiving radially extending can rims.
A device for the thermal treatment of products, especially food and beverages, comprising a container for holding a thermal medium, said container defining a thermal element having walls which are at least partially formed as heat conductive walls, said heat conductive walls being formed in sections having a shape complementry to the product to be treated for maximum heat exchange when one of said sections and said product are brought into mutual surface contact, the sections of said thermal element being rigid, with at least one section being formed as a concave segment of a cylinder, said concave segment having a frontal edge thereof formed with a recess for receiving radially extending can rims, the interior of said container being divided into at least two compartments separated by a dividing wall, said dividing wall being formed with a passageway communicating between said compartments, said passageway being provided with a shutter actuatable from outside of said container for opening and closing said passageway, each of said compartments being formed with at least one filling and discharge opening provided with an opening and closing element for said thermal medium.
