Provided are a heat exchanger, a food handler including the heat exchanger, and a manufacturing method of the heat exchanger. The heat exchanger comprises a main body wherein the plurality of flow channels passes through the inside of the heat exchanger in a first direction and a pair of cover members which is fastened to both ends of the main body in the first direction. The plurality of flow channels is composed of a first flow channel which functions as the path for a first flowing fluid which goes in and out through the cover members and a second flow channel which is connected to the side of the main body. Thermal exchange is performed between the first flowing fluid and the second flowing fluid in the direction wherein the first and second flowing fluids cross each other inside of the main body.

An exhaust valve apparatus and a drier of a food treatment system having the exhaust valve apparatus are disclosed. The drier includes a drum having an input port and a discharge port. A stirring screw is rotatably disposed in inner space of the drum, and includes rotary blades for stirring and crushing food waste put into the drum and a rotating shaft for supporting the rotary blades. A power supply unit is provided on a surface of the drum and provides power to the stirring screw to rotate the stirring screw. A heater is provided on the outer surface of a drum body and provides high temperature heat to the inner space of the drum when electric power is applied to the heater, thus drying the food waste. An exhaust apparatus is mounted to the lower surface of the discharge port and controls the discharge port.
摘要:
The present invention provides a deodorization module and a food waste treatment apparatus having the same. The deodorization module includes a heat exchanger and an electrolytic cell. The heat exchanger conducts heat exchange between exhaust gas discharged from a drying furnace and cooling air drawn into the heat exchanger from the outside of the drying furnace. The electrolytic cell electrolyzes condensate water, formed by the heat exchange process of the heat exchanger, using bipolar packed bed electrolysis to remove offensive odors from the condensate water. The heat exchanger has flow channels therein so that the exhaust gas discharged from the drying furnace and the cooling air drawn from the outside flows along the flow channels in directions that cross each other. The food waste treatment apparatus includes the deodorization module, an intake and exhaust module and a heat exchanger having a stacked structure.

Provided is a wireless communication system between medical devices. A wireless communication apparatus between medical devices using a cognitive technology may receive, from an external frequency coordination database server, state information of frequencies that are available in a predetermined area, and store interference information associated with the frequencies. The communication apparatus may sense an external interference signal that affects the frequencies outside the predetermined area, and an internal interference signal that affects the frequencies within the predetermined area. The communication apparatus may determine a priority of each of the frequencies that are available in the predetermined area based on the interference information, the external interference signal, and the internal interference signal, and may determine a frequency to be assigned based on the priority.
