摘要:
A method and apparatus for the continuous sublimation of a substance includes cascading a material containing a substance capable of sublimation, such as water, between a plurality of trays vertically stacked within a processing zone provided within a processing chamber. A substantially atmospheric environment is maintained within the processing zone at a temperature whereby the substance sublimes forming a sublimate within the environment. The environment containing the sublimate is contacted with a drying agent such as a desiccant to maintain the environment whereby the substance sublimes at substantially atmospheric pressure and at the controlled temperature.

摘要:
An improved ventilated locker includes a pair of sidewalls and a a back wall connecting the sidewalls. A plurality of compartments is defined between the sidewalls, including at least an upper compartment and a lower compartment. A plenum is disposed adjacent the back wall, the plenum configured for connection to an existing HVAC system. At least one ventilation grille is carried by the back wall in fluid communication with at least one of the plurality of compartments and with the plenum. At least one circulation fan is disposed in one of the plurality of compartments to circulate air from the ventilation grilles through the plurality of compartments.
摘要:
A room for bringing products to a specific desired temperature. The room is provided with a heat or cold source and detectors for measuring temperature in the room at a plurality of locations. A number of fans are positioned in the room in the region of a wall, floor or ceiling. In a prepared embodiment, the fans are displacable in a line along a wall, floor or ceiling of the room. In another embodiment, the fans are placed at a regular distance above one another. The line of fans may be displaced backwards and forwards along the wall from one corner of the room to the other. There is also provided a method of defrosting products, such as meat.
摘要:
A device for drying sludge originating in a waste water treatment plant is enclosed in a greenhouse having a floor for receiving a bed of sludge to be dried. The greenhouse employs solar energy. A spreader located in the greenhouse ensures the the sludge is spread over the floor and turned as it progresses along the drying device. Fans are positioned over the spreader to provide for the renewal of air present in said greenhouse. A controller controls start up and shut down of a drying cycle as well as automatic control of all motorized components in response to measurement of the temperature of the surface of the bed of sludge. The controller also takes into account the difference in temperature between the surface of the bed of sludge to be dried and the atmosphere present in the drying plant, equipment in the greenhouse only being started up when this temperature difference reaches a predetermined set point.
