Double-walled crockery comprising a first wall (610) to be heated or cooled, and a second wall (620), wherein between the first wall and the second wall is located a space (630) in which a pouch (640) filled with a phase-change material is accommodated, wherein the pouch is arranged against the first wall of the crockery and wherein a thermally insulating layer is present between the pouch and the second wall of the crockery.

The present invention relates to a grain refrigerator including a housing having a grain storage space formed thereon to discharge grains stored therein, a fixing rod located at the center of the inside lower portion of the housing, dew condensation prevention means fixed to the fixing rod, a support plate located on a top periphery of the dew condensation prevention means, an evaporator disposed on the support plate to generate cool air, and a cooling tube disposed on a top periphery of the support plate on the outside of the evaporator to cool the grains, wherein a first pipe and a second pipe connected to the lower portion of the evaporator pass through a through hole of the support plate and a first drain hole of the dew condensation prevention means and are thus exposed to the outside of the housing.

A hygienic food product to food product heat exchanger (1). The heat exchanger (1) has an elongated and hollow housing (4), a metal tube plate (6) arranged at each of the opposite ends of the elongated housing (4) for defining a closed interior space (10) inside the elongated and hollow housing (4), a plurality of tightly spaced metal tubes (2) axially extending between the tube plates (2) with the ends of the tubes being received in correspondingly tightly spaced holes the tube plates (6) or with the lumen of the tubes being aligned with said correspondingly tightly spaced holes in the tube plates. The metal tubes (2) are sealingly secured to the metal tube plates (6) by a welding joint (20) on the inwardly facing side of the tube plates (6).

This invention relates generally to the distribution of a flushing gas during a packaging process. More specifically, the invention relates to an apparatus and method for the distribution of a flushing gas that displaces an undesirable gas from a packaging container during such a process, the apparatus and method optimizing the displacement of the undesirable gas within the container while also minimizing associated equipment costs and cleaning efforts.

An improved baffle assembly for heat exchanger tubes comprising a shaft and at least one opposing pair of expanding baffles positioned coaxially on the shaft, each expanding baffle comprising a central hub portion and a plurality of extension portions each radiating outward from the hub portion at complementary oblique angles so that the central hub portions of each baffle are spaced apart along the shaft and the distal ends of the extension portions of each baffle are brought into physical contact.

An inventive solution directed to the production of pasta filata type cheese, such as mozzarella, provolone and blends thereof by concurrently and continuously pulling, stretching, cooling and molding cheese through a series of channels, preferably elongated in nature, having enclosed cavities of particular negative dimension for molding purposes. The cheese is cooled by indirect heat transfer through thermal conductive walls of the elongated channels. The cheese is allowed to set as it is formed within the cooling and molding channels. As the cheese is pulled through and out of the distal end of the elongated channels, the series of released cheese ribbons are combined and pulled through a second series of compression channels by which multiple ribbons are compressed together to form larger laminated strips ready for immediate packaging, storage or further processing.

The invention relates to an insert for an exhaust manifold of a heat exchanger device for a cooking appliance comprising a support for two or more pipe sockets having at least one expansion slit, a first cover for the at least one expansion slit on the support, an insulation comprising a support insulation on the first cover and a pipe socket insulation around at least a portion of the pipe socket, and a second cover at least on the pipe socket insulation. It further relates to an exhaust manifold with such an insert, a heat exchanger device with such an exhaust manifold, and a cooking appliance with such a heat exchanger device.

An inventive solution directed to the production and lamination of pasta filata type cheese ribbons, such as mozzarella, provolone and blends thereof by concurrently and continuously pulling, stretching, cooling, and molding cheese through a series of channels, preferably elongated in nature, having enclosed cavities of particular negative dimension for molding purposes. The cheese is cooled by indirect heat transfer through thermal conductive walls of the elongated channels. The cheese is allowed to set as it is formed within the cooling and molding channels.

A flow-type carbonization device includes: a first pipe, in which beverage to be carbonized and carbon dioxide flows and a second pipe, in which beverage to not to be carbonized flows. At least one turbulence generation element is arranged in the first pipe. The first and second pipes are in thermal communication such that heat from a fluid flowing in the second pipe heats the first pipe for sterilizing the first pipe. In one embodiment, the first and second pipe are arranged concentrically.
