An assembly for saturating or aerating a medium with fluid. At least one hollow cylinder having gates and vents embedded within a grain mass. A target section of grain mass is identified and the gates and vents activated to provide influent flow to the target section in both vertical and horizontal directions.

A method of monitoring and controlling a freeze drying process in a freeze drying apparatus having walls, shelves and a number of vials or trays positioned on different areas of the shelves and containing product to be freeze dried. One or more vials or trays are selected that are representative of the positions of all of the vials or trays in different areas of the shelves. One or more heat flux sensors are positioned between the selected vials or trays and adjacent portions of the walls and/or shelves. The heat transfer between the selected vials or trays and the adjacent wall or shelf portions is measured during the freezing and drying stages of the freeze drying process.

Tray assemblies and methods of their use to dry products with sunlight. Such a tray assembly includes at least a first base having four side walls, a bottom wall, legs configured to support the bottom wall above the surface when resting thereon, side wall holes in the side walls, and bottom wall holes in the bottom wall. A cover is releasably coupled to the base to define an enclosure between the cover, the side walls, and the bottom wall. At least one window is provided in the cover to allow infrared radiation to pass therethrough that is absorbed by interior surfaces of the base to cause an increase in a temperature within the enclosure sufficient to increase a rate of drying products located within the enclosure.

A device (1) and a method for drying dialysis filters are provided. The device (1) has a drying chamber (2) and a microwave generating unit (3), which emits microwaves into the drying chamber (2). This allows effectuate rapid drying cost-effectively. The microwave generating unit (3) has a variable frequency and/or a variable power.

A locker includes a pair of spaced-apart upstanding sidewalls and at least one shelf extending between the sidewalls, the shelf and sidewalls defining a compartment. A rack is disposed in the compartment and extends upwardly from the shelf. The rack is dimensioned and configured to support at least a pair of shoulder pads and preferably both pads and a helmet. The rack optionally includes a ventilation system, and the ventilation system may be incorporated into a multi-locker ventilation system.

A locking device for preventing freewheeling of an aeration fan rotor. The locking device comprises an elongated body having a predetermined length. The elongated body is adapted for being disposed through an opening of a fan housing containing the aeration fan rotor therein such that in a first position a first end portion of the elongated body is enabled to interact with the aeration fan rotor for preventing freewheeling of the aeration fan rotor and a second opposite end portion of the elongated body is placed outside the fan housing. The locking device further comprises means for holding the elongated body in the first position and a second position such that in the second position the first end portion of the elongated body is prevented from interacting with the aeration fan rotor.

The present invention relates to a food waste dryer comprising: a main body in which a drying space is formed so that a portion thereof is open to the outside; a front door for closing the open portion of the main body; a drying basket which is disposed in the drying space of the main body and in which food is accommodated; an air circulation unit which includes a heater capable of heating the air of the drying space, and which suctions the air inside the drying space, and then blows, at the food waste, the air heated by the heater so as dry the food waste; a circulation pipe capable of discharging, to the outside through an exhaust pipe, the air that includes steam vaporized during a food waste drying process, and recirculating, to the drying space through a blowing pipe, the air heated by the heater; and a deodorizing device mounted on the outside of the main body so as to adsorb odor particles from the air discharged to the outside through the circulation pipe, thereby enabling the air to be deodorized, wherein the deodorizing device includes a deodorant comprising activated carbon and zeolite. According to the present invention, a fixed amount of steam, which is generated by vaporization and evaporation during the food waste drying process, is maintained, and the adsorption and deodorization performance of the odor particles can be improved.
