A device for conveying and feeding wet material for a cross-flow hot air combine harvester, the device consisting of a hot air pumping part and a material conveying part. The hot air pumping part uses an air suction pump (4) to pump a flow of hot waste air from an engine radiator (1) of the combine harvester by means of an air suction pipeline (3) so as to provide hot air flow for the material conveying and feeding device. The material conveying part consists of a chain harrow-type conveying groove structure (A) and a cross-flow air chamber structure (B), wherein the chain harrow-type conveying groove structure (A) is used for forcibly conveying and feeding a material; and the cross-flow air chamber structure (B) uses hot air to dry the material, blows to assist in feeding the material, and uses a cross-flow air wheel (14) to forcibly feed the material.

A method and apparatus for pasteurizing and drying cannabis plant materials using a microwave-vacuum chamber. The pasteurizing and drying are carried out with no use of ionizing radiation and with rapid drying. Pasteurization is done at a temperature and for a time period that are sufficient to reduce microorganisms to an acceptably low level, while not significantly reducing the psychoactive compounds in the material. In the process, the pressure inside a vacuum chamber is reduced to a first pressure less than atmospheric. The material is maintained in the vacuum chamber at the first pressure at a pasteurizing temperature while irradiating the material with microwave radiation. The pressure is then reduced to a second pressure lower than the first pressure and the material is maintained in the vacuum chamber at the second pressure for a time period at a dehydrating temperature lower than the pasteurizing temperature while irradiating the material with microwave radiation. The pasteurizing and dehydrating steps can be done in the reverse order.

A compressed air drying system is provided for removing moisture from compressed air. The system includes multiple air dryers that each remove moisture from a portion of the compressed air. The air dryers share a reservoir of liquid coolant that is used to cool the compressed air in each of the drying units. The reservoir has inlets for each of the drying units for the liquid coolant to return from the respective unit to the reservoir. The inlets are arranged in the reservoir to mix the incoming liquid coolant from the inlets to ensure that warm coolant from one of the inlets does not flow directly to an outlet of the reservoir.

A method and system for picking up painted panels of different dimensions and finishes includes inserting the painted panels into a selective sorting system having two superimposed mobile conveyor sectors of a predefined length and with a driving motor for the alternate advancement in one of two directions. The two mobile conveyor sectors move vertically synchronously and are arranged alternately and in series with a fixed conveyor sector. After uploading in the selective sorting system, the painted panels are kept inside the selective sorting system for a time sufficient for drying, and are withdrawn through an upload and download system, which includes software memorizing the position of the uploaded panels, actuating the lifting and/or lowering motors of the mobile conveyor sectors, and advancing the mobile conveyor sectors and the fixed conveyor sector so as to move the panels due for a customer order, temporarily storing undesired panels in a buffer.

A method of processing grain from a dryer includes maintaining a transition zone within a volume of received grain, the transition zone being a cross section of the volume of the received grain that is at a same temperature, by cooling and drying the received grain; and extracting cooled grain.

The present disclosure provides for a portable drying mechanism. The mechanism may comprise a grip, shaft, neck, drying panels, and a tip. The shaft may comprise a button to modify the configuration of the portable drying mechanism. The button may release interchangeable components of the portable drying mechanism. The button may allow the shaft to extend. The button may activate an electrical or manual drying response such as, but not limited to, a water vacuum or rotating drying material. The shaft may comprise a hollow cavity for material retention. The shaft may comprise a telescoping aspect that allows for extension and retraction. The neck may comprise a flexible portion to dry containers with complex shapes. The tip may comprise a sensor to verify dryness within a container. The drying panels may comprise a predetermined shape and material that allow the drying panels to dry containers and hard-to-reach areas.

A machine learning method and system for predictive maintenance of a dryer. The method includes obtaining over a communication network, an information associated with the dryer and receiving measurements of a vibration level of one of a process blower, a cassette motor and a regeneration blower associated with the dryer. Further, an anomaly is determined based on at least one of a back pressure and a fault and balance of at least one of the process blower and the regeneration blower is tracked. An alarm for maintenance is raised when one of an anomaly and an off-balance is detected.

A freeze-drying apparatus (1) includes an arrangement of individual product platforms (19) that are supported vertically in a frame (20) in a drying chamber, in which each platform is able to be moved to a shift level, in which lateral guides (20, 21) designed to support a carriage (15) are arranged with a fixed height position, and which cooperate with the guides (16, 18) of a loading and unloading device. All product platforms (19) in the drying chamber can be loaded by repeating this operation cyclically. In order to unload the drying chamber, the arrangement of the product platforms (19) are moved to such a position above the shift level in which the carriage (15) can be moved as far as its rear limit position inside the drying chamber, travelling underneath each loaded product platform (19).

A dryer stand having a base, a body having a first end connected to the base and a second end spaced upward from the base, and a receptacle located in the second end of the body, the receptacle being mounted to the second end of the body is provided. The receptacle can receive a dryer for discharging drying air. The mounting of the receptacle enables at least one of a tilting operation and a rotation operation in a clockwise-counterclockwise direction so that the discharge direction of the drying air can be shifted toward a front-rear direction and clockwise-counterclockwise direction with respect to the dryer stand, either simultaneously or separately, depending on the position and size of the object to be dried.
