Abstract: Heated and humidified air is withdrawn by a blower from the apex of a grain elevator or bin and passed through a heat exchanger to preheat fresh air drawn into the grain elevator or bin. A heater raises the temperature of the preheated fresh air and a further blower forces it into the grain elevator or bin to flow in and about the stored grain to draw moisture therefrom. An auger located at the apex of the grain elevator or bin to transport grain into the grain elevator or bin permits filling of the grain elevator or bin during flow of the drying air.

Abstract: A warm-air hand drying installation has a floor-mounted pedestal with several drying apparatus around its periphery. A single fan supplies air to each apparatus via a central duct when any one of the apparatus is switched on. Each apparatus has a flap valve and a heater. The valve covers either the outlet of the apparatus or a side opening into the pedestal. When any one of the apparatus is switched on, the heater is energized and its valve opens to allow air flow to its outlet and onto the hands of the user. The heaters of other apparatus are not energized and their valves remain positioned such that air flow to the apparatus is directed internally between the pedestal casing and the duct, to the fan inlet. In this way, air flow can be maintained constant regardless of the number of apparatus in use. The fan remains on for a time longer than the heater.

Abstract: First and second ported ducts are associated with a drying chamber. A flow control housing has first and second compartments communicating respectively with the first and second ducts. These compartments also have openings which communicate with atmosphere. A fan is employed which draws air from the drying chamber into one of the ducts and through one of the compartments to atmosphere. At the same time a fan on a common shaft draws in make-up air from the atmosphere and forces it through the other of the compartments and into the other duct for discharge into the dryer. The fans are reversible, and the flow control housing is combined with a double acting heat exchanger which extracts heat from exhaust air in one compartment and transfers it to the other compartment for preheating make-up air. A damper is provided in the flow control housing on the atmosphere side thereof for precise control of exhaust and make-up air.

Both the supply duct formers and the vent duct formers may be equipped with valves to control the flow of air therethrough. The supply duct former is adapted to be lifted to an elevated position when a new layer of hay is deposited on an already dried layer.

Abstract: A shrink oven whose air volume is maintained constant as heated loads are removed and new loads are introduced, to prevent loss of heat and to improve performance. In an oven in which loads are introduced through an entry opening, move through the oven, and exit through another opening, exiting and entering loads are moved so that the rate of load displacement out of the oven at the exit is compensated by the rate of load displacement into the oven at the entry. Special arrangements prevent hot air loss around the sides of the load during the exit and introduction phases. These include close-lying passage walls above and on both sides of the openings, for limiting the air conductance of the gaps about the loads, stacking adjacent loads close together at entry and exit to minimize air leak gaps between the loads, and close positioning of the loads next to doors during opening and closing of doors.

Abstract: On the bottom surface of a store or silo for granular material is placed a system of air channels, which are at one end connected both with an outlet sluice for the grain material and with a blower housing, which is also connected with the free atmosphere. The blower housing is switchable between blowing drying air into the grain through the channels and through wall openings therein and sucking out air from the channels for outlet conveying the grain inwardly through the wall openings and further through the channels to the outlet sluice. By this suction emptying arrangement dust problems in the store are eliminated, and the necessary motor effect is surprisingly low.

The biomass gasifier combustor includes a screw feeder tube having a screw feeder disposed therein. The screw feeder forces the biomass into a first combustion chamber. Primary combustion of the biomass produces a first combustion gas. A venturi gas pump creates a negative pressure region in the gasifier, drawing the first combustion gas into a second combustion chamber.

Abstract: Air chambers underlie the perforated floor of the grain storage chamber of a grain tower. Fans propel air from outside the grain tower into such air chambers. The fans are contained within the tower at bulkheads which divide ones of the air chambers each into a relatively larger air distribution chamber and a relatively smaller air intake chamber. The distribution chamber communicates through the perforations in the perforate floor to aerate grain within the grain compartment. The intake chamber is partly bounded by a portion of the peripheral wall of the tower. The fans draw outside air through limited openings in the tower peripheral wall into such intake chambers.
