Abstract: An apparatus and method are presented for drying and storing laboratory containers which significantly reduce the introduction of contaminants into the containers. A laboratory container system includes one or more containers and a rack for holding the containers in an inverted position. Each container has a base portion, a column portion, and a receptacle portion. A lateral dimension of the base portion is greater than that of the column portion. During use, a container is inverted, and the column portion is inserted between sides of a slot in a flat member of the rack. The spacing between the sides of the slot is sufficient to allow the column portion to pass therebetween, but not the base portion. As a result, the base portion of the container contacts an upper portion of both sides of the slot, and the container is suspended from the rack by the base portion in an inverted position.

Abstract: This invention is a new, energy efficient, environmentally clean grain drying system which consists of two main parts: a hot drying air generator and a modular, portable drying bin. One novel aspect of the air generator is the introduction of a heat pipe design which enhances the efficiency of a dehumidifier heat pump, making its use economically feasible, especially for humid climates. Another novel aspect is the use of advanced burners incorporating antipollution devices. The hot air generator can operate on many sources of energy such as electricity; gasoline; diesel; biomass such as wood, charcoal, or rice husks; or even solar energy. The modular bin is made of several modules which can be disassembled, transported, and reassembled with great ease. The bin design also creates a very low air pressure drop, allowing substantial savings on blower energy. The complete system will offer great benefits for developing countries that are producers of rice, especially for those with humid climates.

Abstract: Apparatus for treating material webs. For the purpose of treating material webs (10), especially drying them, these are acted on by a (heated) gaseous medium via slot nozzles (13, 14) in the area of a drying chamber (11). Depending on the operating conditions and the material web, the flow conditions of the gaseous medium must be capable of being adapted in the area of the material web, since the material web (10) may otherwise be adversely affected, for example as a result of an excessive supply of heat. The slot nozzles (13, 14) are designed in such a way that, in order to change the flow conditions, the exit of the gaseous medium from different nozzle slots can be adjusted by means of a control device, especially a slide device. By means of different outflow directions of the nozzles, an influence can be exerted on the flow conditions and the supply of heat, depending on the operating condition of the drying chamber (11).

Abstract: The invention relates to an apparatus for drying bulk materials, which has a hopper-shaped bulk material container 29 with adjustable side walls 30, by which the container 29 can be adjusted to the amount of bulk material to be dried, by varying the volume of the container and the angle of inclination of the hopper. To dehumidify the drying air, a membrane dryer 12 is provided, which processes preferably the compressed air of a compressed-air system 10, which is previously cleaned by filter elements 13 and 14.
