Abstract: A cooling chamber for drawing down freshly picked and field warmed unitized (for example in cartons stacked on pallets) vegetables, such as cauliflower, is disclosed. Freshly picked cauliflower is placed in rectangular cartons in side-by-side stacks of four extending approximately fourteen cartons high. A group of individual pallets (typically 10 to 12) so loaded are typically placed in the field on a transport chassis and brought to the vicinity of the cooling chamber where they are simultaneously unloaded by a multi-pallet forklift truck. The chamber receives multi-pallet load through an open door and is inserted into the chamber. This chamber has a rear seal which conforms to the periphery of the load and defines in the interstitial volume between the chamber backwall and load a warm air return plenum to forced draft refrigeration apparatus. The load when placed within the chamber has a door closed to form an air-tight seal.

Abstract: A potato seed planter in which seeds are loaded into cups on an endless conveyor from a hopper of a seed receptacle. The conveyor is driven on upper and lower sprockets and arranged on the receptacle with the cups in two parallel rows in staggered constant relationship and moving upwardly through the hopper for seed loading. The cups pass around the upper sprocket, invert and enter a contoured tube thereat and descend in an attached discharge tube to a furrow. The cup bottoms are inclined transversely and support the seeds in their descent against the wall of the discharge tube. At the bottom the seeds are discharged from the planter and guided by the transversely inclined cup bottoms are deposited one by one alternately from one row and then the other in the furrow with precision heretofore unacheived. The planter further comprises a wheeled frame and one or more, attached, laterally extending, flexible frames upon which the receptacle is supported.

The conveyor is driven on upper and lower sprockets and arranged on the receptacle with the cups in two parallel rows in staggered constant relationship and moving upwardly through the hopper for seed loading. The cups pass around the upper sprocket, invert and enter a contoured tube thereat and descend in an attached dicharge tube to a furrow. The cup bottoms are inclined transversely and support the seeds in their descent against the wall of the discharge tube.
