The present invention provides improved apparatus and methods for the monitoring and control of apparatus designed to remove moisture from an initially wet product, such as a continuous dryer (14). The net rate of water removal from the wet product (16) is determined during drying thereof, preferably on a real-time basis. A control assembly (20) is operatively coupled with the dryer (14) and includes sensors (24, 26, 28, 34), which are operatively coupled with a digital controller (38). The controller (38) has a PID controller operable to continuously determine the average net rate of water removal from the product (16).

A system for automatically controlling an electrode drying includes: an oven which provides a space where an electrode sheet is moved and dried, includes a dryer which applies hot air and/or radiant heat to the electrode sheet, and is divided into a plurality of drying sections; a measuring unit which collects information on a dried amount of the electrode sheet and transmits the collected information to a controller; and the controller which determines a dried level of the electrode sheet based on the information on the dried amount received from the measuring unit, and control a drying intensity of the oven according to the determined dried level. Herein, the controller independently controls the plurality of drying sections.

An automatic drying method for a grain dryer has a preparing step, a parameter-setting step, and a multi-stage drying step. The preparing step includes preparing an automatic drying device. The automatic drying device has a body, at least two drying sections, and a detecting module. Each drying section has a hot air inlet, a net-layer base, and at least one exhaust pipe. The detecting module is connected to the body and has at least two moisture meters, at least two temperature sensors, a rotary unit, and a processing unit. The parameter-setting step comprises setting a temperature value and a moisture content of each drying section. The multi-stage drying step comprises conveying pre-dried grains into each drying section, importing hot air into each drying section to dry the pre-dried grains, and adjusting an operating speed of the rotary unit and the temperature of the hot air.

A heating plate is included in an electronic device which also includes a processor, a detecting unit, and a battery. The detecting unit detects values of electrical current in certain parts of the electronic device. The processor determines whether any of the detected values falls within a predetermined range. If the detected value falls within a predetermined range, the processor enables a connection between the battery and the heating plate to cause the heating plate to micro-heat the electronic device to promote or accelerate the evaporation of water or moisture in the electronic device. A method for water and moisture disposal by internal heating is also provided.

Embodiments provide a conveyor for conveying loads of lumber through a lumber kiln or other structure without the use of lumber carts or pushers. The conveyor may include a plurality of rollers arranged to form a flow path through the lumber kiln. Groups of the rollers may be driven by separate drives that are configured to rotate the rollers in opposite rotary directions and/or at variable speeds. Some or all of the drives may be operable independently of the other drives to transport loads of lumber at different speeds/directions in adjacent areas of the lumber kiln. In the event of a fire or a shut-down, the rollers in the proximal half of the kiln and those in the distal half of the kiln can be rotated in opposite directions to evacuate loads quickly from both ends.

A non-invasive method to monitor and control of lyophilization of a frozen product solution to remove solvents is disclosed which includes installing one or more wireless pressure sensors configured to fit into a lyophilization vial tray disposed in a lyophilization chamber having a plurality of product vials, wherein the wireless pressure are distributed among the product vials being lyophilized thereby providing spatial pressure variations, collecting the spatial pressure information from said wireless pressure sensors, calculating sublimation rate of the solution, and adjusting pressure and/or temperature within the lyophilization chamber such that the calculated sublimation rate stays within a predetermined envelope.

Disclosed herein are devices systems and methods for removing moisture from a material via radio frequency electromagnetic wave exposure. A moisture-removal system can include having spaced apart a first and a second electrical conductor extending along a same first direction, each of the first and second electrical conductor comprising opposing broad top and bottom sides, the broad bottom side of the first electrical conductor facing the broad top side of the second electrical conductor. The system includes a material containing moisture at least partially filling the space between the first and the second electrical conductor. The system further includes at least one first wire attached to a first radio frequency generator and to the first end of the first electrical conductor. The system also includes at least one second wire attached to the electrical ground of the first radio frequency generator to the first end of the second electrical conductor.

The present invention provides a drying method to dry a to-be-dried object by allowing the to-be-dried object to contact with gas having a different temperature. The method includes comprising: an introduction process of introducing the to-be-dried object; a first heating/cooling process of heating or cooling the to-be-dried object to have a first temperature; a transportation process of transporting the heated or cooled to-be-dried object; a humidity comparison process of comparing the to-be-dried object humidity of the to-be-dried object with the gas humidity of gas used for dehumidification; an atmosphere temperature adjustment process of adjusting, when the to-be-dried object humidity is high, the temperature of the gas used for dehumidification to a second temperature lower than the first temperature and adjusting, when the gas humidity is high, the temperature of the gas used for dehumidification to the second temperature higher than the first temperature; a dehumidification process of allowing the to-be-dried object to contact with the gas of the second temperature to thereby dehumidify the to-be-dried object; and a removal process of removing the to-be-dried object.
