A fifth step involves cooling the loose mass of long fiber hay. A sixth step involves passing the loose mass of long fiber hay through a hay baler, whereby the loose mass of long fiber hay is formed back into bales.

Abstract: Flux management systems and methods are provided for filtering vaporized flux from the gas of a reflow soldering oven. A flux management system includes a cooling chamber having a cooling medium through which the gas passes. The vaporized flux condenses on the surfaces of the cooling chamber and drips into a collection pan, thereby preventing it from dripping onto circuit boards passing through the oven. The flux management system may further include a self-cleaning feature that includes a compressed gas, which is allowed to enter the cooling chamber through a solenoid valve. The compressed gas may then be directed through a heater, which increases the temperature of the cooling chamber, thereby causing a decrease in viscosity of the flux, which allows it to flow freely into a drain tube. The flux may then be transported by gravity into a collection container.

Abstract: A method and apparatus for drying veneer wherein the feeder upstream of the drying station displaces the veneer at different speeds on the right and left sides of the transport path of the veneer as seen in the direction of transport so as automatically to impart an inclined orientation of the veneer of 20° to 60° to a line perpendicular to the transport direction before the veneer reaches the drying station. In the drying station and the cooling station the veneer retains this inclined orientation and in these stations the veneer is subjected to multiple rerouting or the application of pressure.

Abstract: An method for the formation of coating films on substrates which consists of a main high-temperature and high pressure drying chamber with two additional chambers located in front and behind the working chamber, respectively. The front drying chamber, which is installed between the loading station and the working chamber, is intended for drying the coating films at room temperature, while the rear drying chamber is intended for cooling after drying at high temperature and high pressure in the main working chamber. The front and rear chambers are provided with means for adjusting the respective drying and cooling processes by means of respective heating and cooling systems. This allows initial drying in a wider temperature range and final cooling under most optimum conditions.

Abstract: A liquid removal conveyor system that includes a liquid permeable conveyor belt, a vertically movable agitator and an air suction plenum. The agitator is positioned below and adjacent to the conveyor belt so that, when the agitator moves up and down, it intermittently deflects the conveyor belt. The air suction plenum is positioned below and adjacent to the conveyor belt near the agitator. As the agitator intermittently deflects the conveyor belt, it jostles the material carried on the conveyor belt and the air suction plenum sucks the liquid off the jostled material. The agitator consists of a rotatable shaft and a lobe attached to the shaft. As the shaft rotates, the lobe intermittently deflects the conveyor belt. The agitator lobe may be constructed as a single elongated member that extends across substantially the full width of the conveyor belt, or it may be constructed as two or more discontinuous segments.

Abstract: A continuous-flow grain steeping and slow grain cooling process and apparatus. The continuous charging of hot, partially dried grain from a heated-air dryer into the top of a grain container in a layer of approximately uniform thickness is accomplished by use of grain spreading equipment. The downward flow of grain through the grain container is regulated by thermostatically controlled sweep and discharge augers located in the bottom of the bin. The grain flows at a rate that allows the grain to remain in a top steeping zone for a predetermined period of time, typically from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a continuous upward flow of ambient air is provided by a fan to cool the grain in a bottom cooling zone. The air flow is controlled by a thermostat to provide air flow at a rate that allows grain to remain in the cooling zone for a predetermined cooling time which is dependent on the airflow rate in cfm/bu.

Abstract: A continuous-flow, slow grain cooling process including the charging of hot, partially dried grain from a heated-air grain dryer into the top of a grain container in an even layer. The downward flow of grain through the grain container is regulated at a rate that allows the grain to remain in a top steeping zone for from four to twelve hours. After the initially charged grain is held at the steeping temperature for a predetermined steeping time, a controlled upward flow of ambient air is provided to cool the grain in a bottom cooling zone. The air flow is provided at a rate that allows grain to remain in the cooling zone until it is cooled close to the ambient air temperature, but the upward flow is controlled such that it will not cool any grain until it has been properly steeped. Cooled dry grain from a layer near the bottom is then discharged from the bottom of the grain container.

Abstract: An apparatus is provided for cooling warm granular product. The apparatus includes a grate system having a first grate overlying and second grate. The first grate has a plurality of parallel generally spaced apart members, whereas the second grate has a plurality of parallel equally spaced apart beams. The first and second grate reciprocate relative to each other between a first position in which the product is retained on the grate system and a second position in which the product flows through the grate system. Each of the members in the first grate includes an air flow deflector defining a primary and secondary air outlets for dividing a flow of air into primary and secondary air streams. When the grates are in their relative second position, the secondary air stream is increased to minimize fluidization of the pellet product as it flows through the grate system.
