A plurality of modular units are connected together on a slightly sloped drainage field with a perforated header pipe at the lower side conveying water away from the drainage system. An impermeable flexible liner cushioned on both sides is located below the modular units. The modular units are each made up of rigid boxes that have connecting cross slots at the bottom thereof and vertical perforations there through. The rigid boxes are lined with a drainage fabric that is site specific and have an expanded geosynthetic material therein, which is held in place when filled with porous granular material. High flexural strength mats are connected together over the tops of the modular units. An air inlet pipe connects air to the cross slots, down the sloped drainage field, to the header pipe to drain water from the bulk granular material resting on the high flexural strength mats. Some of the modular units have a pneumatic vibrator connected to a source of pressurized air. The entire system may be quickly disassembled, moved to a different location, and reassembled with the number of modular units being changed according to the circumstances.

A multi-chamber dryer using adjustable conditioned air flow is disclosed. According to one embodiment, an apparatus includes a drying belt configured to receive a product to be dried on a first surface of the drying belt and a heat medium in contact with a second surface of the drying belt. The heat medium is configured to heat the product and is maintained at a pre-determined temperature. The apparatus further includes a manifold that is positioned above the drying belt, where the manifold includes one or more orifices that inject conditioned air laterally across a width of the drying belt to remove evaporated water from the product

A drying device is configured with a sensor corresponding to an air knife-nozzle, and a control switch which suspends an operation of the device when the air knife-nozzle is detected as working abnormally, thereby preventing abnormal products from being produced due to the failure of finding an abnormal condition of the air knife-nozzle in time, ensuring the normal process of the product, and avoiding the nonessential economic loss.

A hybrid kiln system and method for drying material, such as lumber, logs, and timber. A solar air heater uses solar radiation to heat air. The heated air is pushed into a kiln using one or more solar air heater fans. A dehumidifier is also provided to dehumidify and heat the air within the kiln. A method for determining when the solar air heater fans and the dehumidifier should be activated is also provided, and is based upon the temperature difference between the solar air heater's interior and exterior, as well as the relative humidity within the kiln.

A low profile design air tunnel system and method for providing uniform air flow in a refractance window dryer are disclosed. According to one embodiment, a system comprises a conditioned air supply manifold that provides air into a drying chamber. The system has a drying belt directed through the drying chamber. A feed application tray at a first end of the drying belt applies a liquid to the drying belt. The system has an exhaust manifold located at the first end of the drying belt.

A modular oven structure includes a frame, a circulation fan at a top of the frame, a tunnel air inlet chamber, a tunnel air return chamber, a tunnel drying chamber between the tunnel air inlet and tunnel air return chambers, a tunnel air inlet plate including air apertures and between the tunnel air inlet and tunnel drying chambers, a tunnel air return plate including air apertures and between the tunnel air return and tunnel drying chambers, a fan air inlet chamber above the tunnel drying chamber, a fan air outlet chamber between the fan air inlet chamber and the top of the frame, a heater, a temperature control system, and a control device. The temperature control system includes one or more temperature sensors in the tunnel air inlet, tunnel air return, and/or tunnel drying chamber.

Provided is a device (1) for drying a columnar structure (30) supported upright on a supporting surface (2a), wherein a feeding part (5a) for feeding drying gas toward the supporting surface (2a) and a discharge part (6b) for discharging the fed drying gas are both provided in an opposing surface (6a) facing the supporting surface (2a). A plurality of feeding parts (5a) and a plurality of discharge parts (6b) are preferably provided, and the plurality of discharge parts (6b) are preferably symmetrically disposed around one feeding part (5a).

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 lid for curing organic plants. The lid is configured to be secured onto a contain with an open top, wherein the lid includes a gasket located on the bottom side of the lid, wherein the lid further includes one or more valves configured to prevent air from entering the container when the lid is secured, wherein the valve is further configured to allow air to escape the container and enter the container when actuated, wherein the lid includes a plurality of numbers associated with a calendar date and a calendar month annularly arranged on a top surface of the lid, and wherein the lid further includes a plurality of tabs, wherein the plurality of tabs are configured to move bi-directionally and include an opening configured to align and display the plurality of numbers.
