The heat recovery system includes an oven having a treatment air with a treatment air temperature and a treatment air dew point temperature to treat a product or product in process. A zone outlet exhaust waste treatment air following the treatment of the product. A preheating zone includes a preheating inlet for the introduction of preheating air having a preheating air temperature and a preheating air dew point temperature to preheat the product. A transfer duct extends between the zone outlet of the oven and the preheating zone to transfer a portion of waste treatment air from the oven to the preheating zone to create the preheating air to preheat additional product. The preheating air preheats the product in the preheating zone to a product temperature that is at least equal to the treatment air dew point temperature to eliminate surface condensation on the product during treatment in the oven.

A drier for drying boards comprises at least one conduit for directing airflow towards one of the faces of the board. The drier is configured such that at least a portion of the airflow travels across the face of the board along the longitudinal axis of the drier, the longitudinal axis of the drier being the axis along which the board travels as it is dried.

A drying system for a vehicle includes an airflow intake duct structured to be mountable to the vehicle so as to reside exterior of the vehicle. The airflow intake duct includes an intake duct airflow passage structured to receive an airflow therein from outside the vehicle when the vehicle is moving. An airflow duct is structured to be coupled to the intake duct so as to reside in an interior of the vehicle and so as to receive therein the airflow from the intake duct when the intake duct is mounted exterior of the vehicle. The airflow duct includes a plurality of holes structured to enable discharge of a portion of the airflow from the airflow duct into the interior of the vehicle.

A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.

A tonneau cover for a vehicle cargo includes a first panel having a first opening structured to enable fluid communication between a first side of the first panel and a second side of the first panel opposite the first side. The tonneau cover defines at least one airflow passage in fluid communication with the first opening and extending along the second side of the first panel.

The present disclosure provides a smart clothes drying device and a smart clothes drying method. The smart clothes drying device includes a light intensity sensor, an integrated controller, an umbrella and at least one clothes hanger. The light intensity sensor is to sense light intensity and output a light intensity signal. The integrated controller is to receive the light intensity signal and control opening or closing of the umbrella according to a comparison result of comparing the light intensity signal with a closing light intensity threshold or an opening light intensity threshold in such a manner that the integrated controller controls opening the umbrella when the light intensity signal is greater than the opening light intensity threshold, and the integrated controller controls closing the umbrella when the light intensity signal is less than the closing light intensity threshold.

A system for heating, drying or curing an object, the system comprising a housing having a first wall and at least one second wall adjacent the first wall. The first wall and at least one second wall define an interior for holding an object to be heated, dried or cured. The system also includes an air plenum adjacent to, covering and disposed inward from the first wall, and at least one air plenum opening in the air plenum to supply air into the interior. A fan is disposed in the one air plenum opening. The system also includes a ductwork assembly adjacent to, covering and disposed inward from the second wall. The ductwork assembly is in air-communication with the air plenum, and has a ductwork opening so that substantially all air circulation in the interior is between the air plenum opening and the ductwork opening.

A tonneau cover for a vehicle cargo bed includes at least one first airflow passage extending between a first side of the tonneau cover and a second side of the tonneau cover opposite the first side, and at least one second airflow passage separate from the first airflow passage and extending between the second side of the tonneau cover and at least one side of the tonneau cover other than the second side.

A tonneau cover for a vehicle cargo includes a first panel having a first opening structured to enable fluid communication between a first side of the first panel and a second side of the first panel opposite the first side. The tonneau cover defines at least one airflow passage in fluid communication with the first opening and extending along the second side of the first panel.

A method of drying laundry in a laundry treating appliance having a treating chamber in which the laundry is received for drying comprises moving the treating chamber to redistribute the laundry, supplying air to the treating chamber to define a supply air flow, exhausting the supplied air from the treating chamber to define an exhaust air flow, heating the air supplied to the treating chamber by actuating a heater at full output to define a first heating phase and then cycling the heater ON/OFF to define a second heating phase.
