A grain dying system for a grain bin that includes a heating unit arranged in a proximity of the grain bin and ducting connected at one end to the heating unit and another end to a grain drying adaptor. The grain drying adaptor is connected at one end to the ducting and at another end to a fain unit of an aeration system for the grain bin. The fan unit is attached to the grain drying adaptor. The grain drying adaptor is configured to introduce a blend of heated air from the heating unit and ambient air from outside the grain drying adaptor into the aeration system of the grain bin.

A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.

A heat exchanger and dehumidifier apparatus for use in grain drying operations or other applications. The heat exchanger and dehumidifier apparatus includes a shroud having an air inlet end and an air discharge end. First, second, third and fourth heat exchangers and dehumidifier assemblies are positioned in the shroud which define an air passageway extending therethrough having an inlet end and a discharge end. A blower is positioned at the discharge end of the shroud for blowing heated and dehumidified air therefrom.

A drying apparatus promotes drying of a wet item while protecting a surrounding environment from moisture escaping the wet item as it dries. The apparatus includes a waterproof casing comprising one or more waterproof materials and constructed (a) to receive a wet item and (b) prevent the moisture in the wet item from contacting items in the surrounding environment. The waterproof casing also includes a drain structure at one end having an opening through which moisture from the wet item escapes the drying apparatus and one or more rigid structures extending from within the waterproof casing through the opening to create a pathway for the escaping moisture. The drying apparatus also has an intake vent positioned to draw air into the drying apparatus and direct the air over the wet item within the apparatus and through the opening in the drain structure.

A portable electromagnetic wave drying apparatus is provided for the in-situ reduction of moisture in structural members within a wood frame construction. The apparatus comprises at least one electromagnetic wave generation assembly and an electromagnetic wave applicator. Also provided is an electromagnetic wave treatment method for the in-situ reduction of moisture content in a structural member within a wood frame construction. The method comprises contacting a portion of the structural member with electromagnetic waves for a period of not more than 30 minutes and then allowing the structural member to rest for a period of not more than 90 minutes. The apparatus and method are useful in the remediation of wood frame structures that have been exposed to flood waters.

A modular produce drying tunnel system comprising a loading module, at least one drying module, an end module, and a conveyor. The drying module may comprise at least one gullwing style access door which houses an independent heating element and a blower and which opens upwardly to provide broad access to the interior of the tunnel. The system may be customizable for different types and volumes of produce, comprising a plurality of drying modules, each having at least one access door, and each access door having an independent heating element and blower.

A dryer for installation on a self-propelled machine, such as a combine harvester, with recovery of the exhausted thermal energy coming from the endothermic engine of the latter. The dryer is of the on-line type and comprises at least two feed screws, internally to which grain is moved towards a tank and dried by the hot air coming from a first and second heat exchangers respectively, the first heat exchanger being crossed by the high temperature exhaust fumes of said endothermic engine and the second heat exchanger by the cooling liquid.

Methods and apparatus for drying harvested products using a mobile drying system are disclosed. According to some embodiments, a refractance window dryer is implemented on a mobile platform that includes two mobile units (e.g., trailers or transportable skid mounted assemblies) that may be transported to a remote location (e.g., at a harvest location). A first mobile unit may include a refractance window dryer module, and a second mobile unit may include utility equipment that supports operation of the refractance window dryer module.

A dewatering device for aggregate product can be used to retro-fit existing aggregate product dewatering facilities in order to more efficiently capture product. The dewatering device can be movable to allow for the portability of the device relative to existing dewatering facilities. The device is adapted to receive a slurry of aggregate product and water and to vibrate to dry the aggregate product. A recycle system is included to receive any fines that may otherwise be lost by the system. The recycle system captures the fines and redirects them back towards the vibrating process of the vibrating device to direct them towards an exit of the vibrating device in order to use said fines as well as the other dewatered aggregate product. The portability of the device allows the device to be used with the existing facilities without the need to completely replace existing components for dewatering aggregate product.
