Embodiment Construction

[0086] figure 1 A first example of the apparatus of the present invention is shown in the present invention is shown. The apparatus includes a drum type dryer 1, a discharge housing 2, a cleaning device 3 (multi-tube cyclone separator), two heat exchanger 4 parallel, has a combustion chamber for fuel / combustion air mixture. Multi-fuel burner 5, filter 6, and chimney 7. Dry steam generated by, for example, wood chips within the drying drum dryer 1 is introduced into the dry circuit. The dry steam fan 8 is disposed between the drum dryer 1 and the cleaning device 3, and the burner exhaust fan 9 is disposed between the filter 6 and the chimney 7. The dryer 1 can be provided with a deceleration region 11 and a metering device 12.

[0087]A bulk article is supplied to the drum dryer 1, such as wood chips and / or wood fibers. The drying gas supplied to the drum dryer 1 is heated via a heat exchanger 4 and has a temperature in the range of from about 250 ° C to about 600 ° C. The dry...

Abstract

The present invention relates to an apparatus and a method for continuously drying bulk goods, in particular wood fibers and / or wood chips, in a dryer, wherein the drying vapors are led to a dryer (1)circuit, in which the drying vapors are indirectly heated via a heat-exchanger (4) and are conducted to the dryer again.

Description

Technical field [0001] The present invention relates to an apparatus and method for continuously drying a bulk item, in particular wood fiber and / or wood chip, wherein the dry steam is introduced to a dryer circuit in a dryer circuit. The drying vapor is indirectly heated via a heat exchanger and is again introduced to the dryer. Background technique [0002] The fabrication made of wood is basically based on the mixed wood chip, in particular wood fiber and / or wood chips. For example, the particle plate is composed of a small wood having different thicknesses, which are pressed with the binder under the application of high pressure to form a plate. In the case of or without additional binders, the wood fiber plate is made of wood fibers. [0003] Dry minced wood chips before being pressed into plates. This is typically carried out in a so-called roller dryer, wherein the item to be dried, more accurately (Respective) bulk items are moved in the heated rotary tube. During the...
