Method for drying veneers
An apparatus and method is provided to dry veneer or other items by vaporization of moisture in the item. Apparatus has an insulated chamber with a frame and a drawer with a door. A mesh surface of the drawer supports item for drying with a heater at sub-atmospheric pressure inside of the chamber. Item is placed on the layer of mesh of the drawer of the apparatus and secured with fasteners such as another layer of mesh. The drawer with fastened item is placed into the chamber of the apparatus. With the drawer fully engaged within the chamber, the drying apparatus is closed with an airtight seal. A pump draws a vacuum in the chamber and heat is directed at the item to raise the temperature of the item to less than 160° F., particularly between 120° F. to 150° F. Apparatus can dry veneer in less than five minutes.
1. A method of drying an item, the method comprising the steps of:
placing the item on a layer of mesh of a drawer of a drying apparatus;
securing the item to the layer of mesh with at least one fastener;
placing the drawer within a chamber of the drying apparatus with an airtight seal;
drawing a vacuum on the chamber with a pump;
directing heat at the item to raise the temperature of the item to less than 160° F.; and
removing the item substantially dried from the chamber.
2. The method according to claim 1 , wherein the drying apparatus comprises a chamber capable of sealed closure with a door of a drawer with a layer of mesh adapted to slide into the chamber in a position substantially parallel to a heating element adjacent a wall inside of the chamber.
3. The method according to claim 1 , wherein the item is heated to a temperature between 120° F. and 150° F.
4. The method according to claim 1 , wherein sensors are provided to monitor the vacumri pressure and temperature in the chamber and temperature of the item.
5. The method according to claim 1 , wherein the vacuum and heat directed at the item are selected to cause substantially all moisture removal from the item.
6. The method according to claim 5 , wherein directing heat at the item completes the substantially all moisture removal from the item in less than five minutes.
