The cap design and interior air delivery and air exit designs provide optimal air flow into, through, and out of the apparatus. The spaced apart nozzles provide multi-levels of air delivery. The apparatus provides temperature controlled heated air. The selectively positioned nozzle openings and fan control provide selectively delivered air flow amounts.

  • Patent number: 7891115
    Abstract: A material drying apparatus for removing moisture from material positioned in an envelope interior. The apparatus comprises an inlet structure, an air removal assembly to remove air from the interior, and a moisture removal assembly for removing moisture from gases from the interior. The assembly comprises a first moisture removal structure, a second moisture removal structure, and a heat pump for transferring heat in a selected direction between the first and second moisture removal structures. The heat pump alternately heats a heat exchanger of one moisture removal structure and cooling a heat exchanger of the other moisture removal structures. The apparatus comprises a control apparatus for controlling operation of the first and second moisture removal assemblies and the heat pump. The control apparatus is configured to sense a condition of the apparatus and reverse operation of the heat pump upon detecting that the condition has passed a predetermined level.

  • Publication number: 20100212182
    Abstract: A system and method for drying cavities loaded with high level waste (“HLW”) is devised. The invention utilizes a non-intrusive procedure that is based on monitoring the dew point temperature of a non-reactive gas that is circulated through the cavity. In one aspect, the invention is a system for drying a cavity loaded with HLW comprising: a canister forming the cavity, the cavity having an inlet and an outlet; a source of non-reactive gas; means for flowing the non-reactive gas from the source of non-reactive gas through the cavity; and means for repetitively measuring the dew point temperature of the non-reactive gas exiting the cavity.

  • Publication number: 20100192405
    Abstract: A dryer fire protection system has a control circuit for controlling power supplied from a source, via a power cord comprising a neutral line and at least one entry live line, to a load connected with the neutral line and at least one load live line. The control circuit has a relay comprising an electromagnet and a normally open switch. The energized electromagnet closes the switch to allow power to flow between the entry live line and corresponding load live line. An electromagnet control circuit connected between the entry line and neutral line has a plurality of normally closed thermostats in series and mounted within the cabinet external of a drum and ducting associated therewith. Power normally flows through the electromagnetic circuit to energize the electromagnet. Excessive cabinet heat opens at least one thermostat to interrupt power to the electromagnet circuit to de-energize the electromagnet to open the switch.

  • Patent number: 7765715
    Abstract: A drying apparatus and a controlling method thereof are provided. During an initial phase of drying operation according to a selected drying cycle, a point of terminating the drying operation is calculated based on a moisture level sensed by a moisture sensor and a moisture output quantity stored in the storage. Drying is performed up to the calculated point of drying operation termination.

  • Publication number: 20100174668
    Abstract: A clothes dryer is provided comprising one or more power consuming functions and a controller in signal communication with an associated utility. The controller can receive and process a signal from the associated utility indicative of current cost of supplied energy. The controller operates the clothes dryer in one of a normal operating mode and an energy savings mode based on the received signal. The controller is configured to change the power consuming functions by adjusting one or more of an operation schedule, an operation delay, an operation adjustment, and a selective deactivation of at least one of the one or more power consuming functions to reduce power consumption of the clothes dryer in the energy savings mode.

    Abstract: A clothes dryer includes a motor adapted to be mounted on a frame of the dryer for driving a dryer belt to rotate a drum of the dryer. The motor includes a rotor adapted to rotate the belt, at least one winding energizable to cause rotation of the rotor, and a first switch operable to control energization of the winding. A second switch has a sensor for sensing belt breakage. The second switch is mounted on the first switch and is electrically connected to the winding so that when the belt is no longer sensed, the second switch stops operation of the winding and thereby stops rotation of the rotor.
