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 material drying system, method, and control system therefor that provides for consistent and efficient drying of various materials is disclosed. In certain embodiments, a vacuum kiln can use various temperature measurements to reduce the chance of overheating the materials. In certain embodiments, a vacuum kiln (or a control system therefore) can use sensed information, such as the temperature differential across a platen assembly or the duty cycle of a vacuum pump, to determine when a large group of material has reached a substantially uniform dryness level. In certain embodiments, a vacuum kiln as disclosed herein can reduce checking, splitting, over-drying, and under-drying of material without requiring parameters from a user.

Methods and systems for correction of water content measurements include determining an apparent water content measurement of a sample material while the sample material is dried in ambient vapor pressure conditions, determining a correction value that represents a relationship between the apparent water content and the vapor pressure, and correcting the apparent water content measurement based on the correction value. These methods and systems can reduce cost, measurement time, and error in water content measurement for products that lose water over time, such as while being dried or cured.

A method of using a vacuum chamber to assist in detecting and removing moisture from an instrument having a lumen, e.g., an endoscope is disclosed. Second derivatives of pressure with respect to time are calculated and differences therebetween summed. These summations may be compared to a threshold value to determine whether residual moisture remains on the instrument in the chamber. The vacuum chamber may include a rack for hanging instruments having lumens, such as endoscopes.
