Abstract: An exhaust hood and related methods for exhausting fumes are disclosed. The exhaust hood comprises a housing forming a collection region having an entry portion and an upper portion disposed above the entry portion, an exhaust inlet coupled with the housing and configured to draw air from the entry and upper portions, and a supply assembly coupled with the housing and configured to output a flow of supply air. The supply assembly is configured to direct a first portion of the supply air across the collection region generally towards the exhaust inlet and direct a second portion of the supply air generally downward away from the collection area. The directed first portion of the supply air divides the collection region into the entry and upper portions. The portion of the supply air directed into at least the first portion or the second portion can be adjustable.

Abstract: A method for maintaining produce in a near “just harvested” state during transport in a truck trailer by limiting the formation of Ethylene, scrubbing the atmosphere to remove any that does form, and by exhausting the atmosphere of any residual Ethylene.

Abstract: A cargo container has a top, bottom, and sides. The cargo container includes a ventilation unit having an air outlet. The cargo container also includes a ventilated floor, which has an air channel, and a baffle plate assembly configured to direct air from the air outlet of the ventilation unit into the air channel of the ventilated floor. The baffle plate assembly includes a first plate, which is attached to the bottom of the cargo container to remain fixed, and a second plate, which is hinged to the first plate to move from an open position to a closed position. When the second plate is in the open position, a gap between the air outlet of the ventilation unit and the air channel of the ventilated floor is exposed. When the second plate is in the closed position, the gap between the air outlet of the ventilation unit and the air channel of the ventilated floor is covered.
