In the embodiment of FIG. The preheating of the material 18, as well as preventing condensation on it, also reduces the amount of necessary external heat input into the dryer and the time needed to dry the moist material as it passes through the enclosure NZA en. As the air or gas is recirculated it becomes heated and begins to generate steam within the enclosure 10 from the moisture in the material The following is a more detailed description of embodiments of the invention, by way of example, reference being made to the accompanying drawings in which:.
In packaging and greenhouse coverings, transparency of the films is important and fogging has to be precluded.

EPA1 en. Such arrangement is obviously unsuitable for the drying of articles or materials which might be damaged or otherwise adversely affected by immersion in water.
In the diagrammatic drawing the ducts 11 and 12, and conveyors 13 and 15 are shown as being steeply inclined but they could instead be inclined at an angle which is sufficiently shallow for the conveyor to provide an inclined surface on which the materials simply rest. These layers act as barriers to the escape of steam from the enclosure while at the same time permitting the free conveyance of material along the ducts and into and out of the enclosure SGA1 en. In use, superheated steam tending to pass downwardly along the ducts meets external air tending to pass upwardly along the ducts and forms within each duct a temperature and density differential stratification layer

|Print resolution of xdpi is offered, together with optical resolution of dpi.
Atrium of the Maritim Hotel has flight theme. The pipe 53 may pass through an additional condenser not shown located either inside or outside the enclosure 10, the condenser pre-heating the slurry so that no condensation of moisture on the slurry can occur as it is passed into the enclosure 10, thus reducing both the external thermal energy input and the time required for drying.

If the discharge flow exceeds the inward flow cold ambient air will enter the oven and change the internal recirculating air temperature, to the detriment of the process.
In the arrangement of FIG. For example, the drying conveyor may be of generally U-shaped configuration.

His research used five-ply beech plywood and he found that construction of the moulded plywood seat 'buckets' had to be modified. Any national markings will be explicitly forbidden. PLA1 en. The apparatus may also include a closable outlet from the enclosure whereby the outlet, when opened, allows superheated steam in the enclosure to be displaced by external air or other gas passing into the enclosure through said inlet or outlet ducts.

It is therefore necessary to provide some sort of substantially gas-tight seal or barrier which will permit the passage of the materials into and out of the enclosure while at the same time preventing the escape of the superheated steam. Method and heat-exchanger for preheating broken glass and glass-batching melt-goods or similar bulk goods using a heating gas. Apparatus according to claim 1, wherein said means for generating superheated steam include external steam generating means separate from the enclosure, and conduit means for delivering externally generated steam to the enclosure.
Much to learn 22 January I claim: 1. Sloping drainage runnels not shown may be provided in the lower end of the duct 12 to prevent the resulting condensate from dripping onto the dried material.

Liu and his research partner, Thomas Amidon, director of the Biorefinery Research and the greenhouse gas emissions and energy associated with wood pellets.
His subject was Testing of innovative detection methods on recovered wood for particleboard production.
The condenser 36 is located within a chamber 37 forming part of the lower portion 29 of the inlet duct 11 so as to provide a heat source within that chamber. DEA1 en. Any steam and condensate discharged from the condenser 43 is delivered through a conduit 44 to a heat exchanger 45 located in a chamber 46 in the lower portion 29 of the inlet duct The materials may thus pass freely into and out of the enclosure 10 without having to pass through any mechanical barrier.
In practice there will be some downward escape of heated air, and hoods usually have to be provided, as shown, to lead the escaping air upwards away from the apparatus.

|Mr Coutrot pointed out that biological resins have disadvantages, including board properties, while pMDI is the only chemical alternative, but only for some uses.
GBA en. It is known to dry moist materials. In the arrangement of FIG. In any of the above arrangements the vent duct may include a condenser to condense said portion of superheated steam vented from the enclosure, so as to recover thermal energy therefrom.

This enables the thermally insulated walls and top of the enclosure 10 to be made of lightweight materials and constructed in the form of a lid resting in gas-tight sealing manner on the perimeter of the base of the enclosure
