摘要： A process and device for energy-efficient drying of green malt in a drying kiln using a rotational speed-modulated fan for directing an air mass flow through a bed of drying material for the green malt. The drying is implemented for a specified maximum kiln time. To do this, grain moisture content and a grain mass of a grain are detected, which constitutes a basis for the bed of drying material of the green malt after steeping and germinating, Furthermore, an ambient air humidity of an ambient air used for the air mass flow and a plurality of weather forecast data are detected at least with respect to the ambient air humidity and, during drying, a moisture content of the drying material of the green malt is monitored up to a specified limit. A rotational speed modulation of the fan is controlled such that the specified maximum kiln time is reached.

摘要： Systems for drying granular materials, such as resin granulates, powdered materials, and agricultural grains, can include a storage vessel for holding the granular material; a drying hopper having a body defining an interior volume configured to receive the granular material; a diffuser configured to direct process air into the interior volume; a vacuum source for transferring the granular material from the storage vessel and to the drying hopper; and a moisture sensor for determining a moisture content of the granular material at a location upstream of the drying hopper. At least one of the residence time of the granular material within the drying hopper, and the temperature, humidity, and flow rate of the process air are regulated based on the moisture content of the granular material measured upstream of the drying hopper at, for example, the storage vessel.

摘要： A microwave vacuum low-temperature drying machine includes a frame and a conveyor. One side of the interior of the frame is provided with a drying chamber, and the other side of the interior of the frame is provided with an equipment chamber. An inner wall of the drying chamber is provided with a drying system. The drying system includes a first drying assembly located at upper parts of inner walls at two sides of the drying chamber, second drying assemblies respectively located at middle and lower parts of the inner walls at the two sides of the drying chamber, and a third drying assembly located between the second drying assembly at the middle parts and the second drying assembly at the lower parts. The machine can handle a large and high stacked material, and achieve uniform inside and outside drying of the stacked material, with high drying efficiency.

摘要： A method and system for drying an active part of an electric transformer, by continuously determining a moisture content in the solid insulations during vapor phase drying in a drying oven and stopping this drying when an equilibrium moisture content is reached. Then, continuously determining a moisture content in the solid insulations during the retightening and geometric adjustment phase of the active part outside the drying oven and continuing with the determination of moisture content during vacuum drying once the active part is inside the hermetically sealed tank, and stopping vacuum drying when an equilibrium moisture content is reached in the solid insulations. The determination of moisture content and equilibrium moisture content is carried out by applying the diffusion equation.

摘要： A method for drying at least one sample of material is provided. The method includes placing the at least one sample of material into a chamber and then sealing the chamber. The method includes applying a vacuum to the chamber in order to reduce the pressure therein. The method includes heating the at least one sample using electromagnetic energy while applying the vacuum to the chamber. The method includes measuring at least one condition of the chamber and determining that the sample is dry based on the at least one monitored condition.

摘要： An apparatus is used for cleaning and drying applicator tools, such as brushes, cosmetic applicators, or cosmetic tools. The apparatus according to various embodiments includes an applicator tool holder configured to hold multiple applicators of various sizes with the applicator heads facing down. The applicator tool cleaning apparatus has a cleaning chamber that can dispense liquid to saturate the applicator heads and contact the applicator heads with a textured surface to dislodge collected materials on the applicator heads and a drying chamber where drying mechanisms blow air or dissipate heat at the applicator heads until dried. The applicator tool holder may be moved vertically between the cleaning chamber and the drying chamber via a motor and drive mechanism. Alternatively, the applicator tool holder may be flipped such that the applicator heads are facing upwards and aligned with the drying mechanisms.

摘要： Near InfraRed NIR technology, including NIR cameras and detectors, and machine learning methods and systems, including one or more Machine Learning (ML) based moisture level detection models, are used to accurately identify moisture content and the specific locations of the moisture on an entire surface of a veneer sheet or other wood product and provide moisture level prediction data for the veneer sheet or other wood product. Based on the moisture level prediction data for a given wood product, one or more actions are taken with respect to wood product to ensure the wood product is put to the most efficient, effective, and valuable use.

摘要： A kiln for drying and processing lumber packages is provided. The kiln generally includes at least one end chamber, a drying chamber adjacent to the end chamber, a first lumber conveying line configured to transport the lumber packages in a first direction through the end chamber and the drying chamber, and a second lumber conveying line configured to transport the lumber packages in a second direction through the end chamber and the drying chamber. The conveying lines may be countercurrent or uniflow. The kiln may further include a heat distributor in the end chamber to distribute heat into the end chamber in addition to heat from the drying chamber along the first and second lumber conveying lines. The heat distributor may include a distribution duct receiving heat from a drying chamber distribution duct or a heater inlet duct, a heat exchanger, a radiative heating element, or a combination thereof.

摘要： A fluidized bed dryer may include a deck, an eccentric, and a blower. A heater may or may not be included. The deck of the fluidized bed dryer may vibrate due to motion of the eccentric. The blower may blow air through the deck of the fluidized bed dryer to dry material on the deck. As the material dries, the material moves across the deck, due to the vibration. The deck bed depth may be increased, which may allow for even process air flow distribution and control of conveyance speed and residence time. The fluidized bed dryer may include a controller configured to implement a drying process that may include one or more of temperature, moisture content, and relative humidity data to optimize product throughput while ensuring a desired degree of dryness.
