  • Patent number: 6038785
    Abstract: A vacuum dryer panel for a leather drying machine wherein a dryer panel comprising a porous screen is mounted over a perforated plate on the underside of a vacuum chamber positioned above a heated drying table on which leather skins are dried. The dryer panel comprises a layer of fine mesh screen preferably formed of a synthetic resin material mounted on a porous backing preferably formed of a synthetic resin material. The backing material is adapted to be mounted adjacent an outer side of the perforated plate and provides porosity between the screen and adjacent openings of the perforated plate. The backing material is sufficiently rigid to prevent the screen material from being pulled into openings in the perforated plate by a negative pressure on the upper side of the plate, so as to prevent marks in the dried leather. The edges of the dryer panel are folded over and incorporate reinforcing strips. Threaded fasteners fit through spaced openings in the edges for mounting the dryer panel to a vacuum chamber.

  • Patent number: 4612710
    Abstract: An apparatus for drying gel slabs supplies heat to a horizontal gel slab from a heating plate above the slab, while drawing a vacuum beneath. The heating plate is weighted and has a flat lower surface at least coextensive with the gel slab. The slab itself is placed on a porous support pad in a vacuum chamber enclosed at the top with a flexible cover which clings to the gel and seals to the perimeter of the chamber when a vacuum is applied from below. The heating plate rests on top of the cover under gravitational force, providing even heating across the entire expanse of the gel slab and for the entire duration of the drying process, resulting in a continuous and uniform vapor flow downward from the gel slab, a minimization of internal stresses, and reduced susceptibility of the gel to cracking.

  • Patent number: 4193207
    Abstract: A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure.Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface.

  • Patent number: 4188878
    Abstract: A restraining device is used in a dry kiln with a load of green lumber in order to reduce warpage during drying and cooling. A single restraint device is comprised of a pair of inverted leaf springs joined together at their centers and having a strap extending from one end of the top spring about the load of lumber and terminating at the other end of the top spring together with a tensioning device for the strap. Before the load of lumber is placed in the dry kiln, the tensioning device will draw down both the bottom and top leaf springs close to the load where the tensioning device will lock them in place. During drying, as the load shrinks, the top spring will be relaxed while the bottom spring will maintain a force across the width of the load, thereby substantially reducing warp.
