A drying apparatus includes a heating mechanism configured to heat an inside of a drying oven in which paint applied to a workpiece is dried. The inside of the drying oven is partitioned into an upper region and a lower region by a partition plate. The drying oven has an air passage that enables air to flow between the upper region and the lower region. A metal member to which paint is applied is conveyed into the upper region, and a resin member to which paint is applied is conveyed into the lower region.

An apparatus for thermo-transformation of wood planks comprises a chamber delimited by upright perforated walls, a top wall and end walls and having a closable entry for receiving wood planks into the chamber. A shell surrounds the chamber and is spaced therefrom to define a first vertical plenum with the first perforated wall, a second vertical plenum with the second perforated wall, and a horizontal plenum with the top wall. A ventilation system is in fluid communication with the plenums to produce a flow of heated air in the plenums. Vanes are actuatable to close/open access to the vertical plenums, to allow heated air into at least one of the vertical plenums, through the chamber via the perforated walls, and out from at least the other of the vertical plenums, to return to the ventilation system. A method for the thermo-transformation of wood is also provided.

The method for filtering an air flow in a grain dryer to permit recycling of the air includes entering an external air flow into the grain dryer; pouring a grain flow by gravity into the grain dryer; passing the external air flow through the grain flow in a direction substantially perpendicular to the direction of the grain flow; filtering the air flow after passing through the grain flow so as to retain particles present in the air flow; heating the filtered flow and directing the filtered flow upstream of the grain flow, such that the filtered flow passes again through the grain flow; and blowing the particles proceeding from the filtering. The invention also relates to a device for implementing this method.
摘要:
An agricultural product treatment system. A preferred embodiment of the invention includes a truncated conical section which has a small diameter at one end in fluid communication with a conduit array conveying particulate matter from the DT. An open large diameter end of the structure is axially coextensive and coaxial with an expanded diameter conduit portion.
摘要:
The present invention provides an indirect heat-drying apparatus that is resistant to adhesion of the substance to be dried on heating pipes and gives a product having a desired and stabilized liquid content.The present invention relates to an indirect heat-drying apparatus, comprising two indirect-heating rotary dryers, i.e., the first and second indirect-heating rotary dryers that are arranged in series so that the dried substance from the first indirect-heating rotary dryer is supplied to and dried in the second indirect-heating rotary dryer as the substance to be dried; and a carrier gas-supplying means of supplying the carrier gas co-currently in the first indirect-heating rotary dryer and counter-currently in the second indirect-heating rotary dryer, with respect to the flow direction from the substance to be dried.
摘要:
An apparatus for drying and powderizing organic material. The apparatus includes at least one chamber including: an intake adapted to receive warm air and the material into the at least one chamber, and an outlet adapted to transport warm air and powder out of the at least one chamber; at least one rotatable drive shaft in the at least one chamber adapted to rotated; and at least one blade assembly on the at least one drive shaft. The blade assembly includes a blade hub about the rotatable drive shaft and at least one blade coupled to the blade hub, wherein the at least one blade is adapted to powderize the material to expose a surface of the material to the warm air so that moisture in the material evaporates into the warm air.

A biomass torrefaction system includes a mill which receives a raw biomass feedstock and operates at temperatures above 400 F (204 C) to generate a dusty flue gas which contains a milled biomass product.
摘要:
A method and apparatus are provided for reducing the VOC and CO content of dryer offgas that is discharged into the atmosphere from a moist organic product drying process using thermal oxidizing apparatus that includes a furnace, mixing chamber, thermal oxidizer, tempering chamber, and an indirect gas-to-gas heat exchanger. The dryer offgas is separated into two portions, with a larger portion being preheated by indirect heat exchange with the hot gaseous output from the thermal oxidizer. The non-preheated portion is directed to a rotary waste heat evaporator in which moisture is removed therefrom. The preheated portion is recycled to the hot gas inlet of the dryer and serves the function of dryer heat transfer media. By removing moisture from the non-preheated portion of the offgas that is directed to the thermal oxidizing apparatus, simultaneous achievement of thermal oxidizer temperatures of 1600° F. or greater, and an adequate oxygen concentration of 5% by volume is achieved for optimized thermal oxidation of carbon monoxide and volatile organic compounds.
