Pan driers

Compartment driers are closets or even rooms in which the material is spread on trays or in shallow pans. The operation is often discontinuous in order to make it continuous, the pans may be placed on trucks traveling on rails, and these are pushed through a tunnel in which warm air circulates. Belt driers and chain driers have similar goals. 

Drying Rooms For drydng materials that cannot be agitated, the drying room, and tray drier (which there are many varieties) can be used. In the former, the material may be spread on pans and these stacked in a rack, which leaves a space between the trays for air circulation. The room has loosely fitted side walls of plaster board, or similar material, or even canvas, and contains a steam radiator. The natural circulation of the warm air removes the moisture the drying period is generally long, for example, one or two days. 

Tray, Truck, and Tunnel Driers In order to accelerate drying, the closet is factory-built with tight walls. It forms a box, and the air is passed by means of a fan over a radiator or over finned tubes and then over the trays. A portion of the air escapes at the discharge opening the remainder is reheated and recirculated. An amount of new air equivalent to the volume discharged is admitted at the fan. Secondary heating tubes are placed in the path of the air to restore their temperature and heat content. In the tray drier, shallow pans 2 ft by 3 ft by 2 in. deep, for example, are placed on a rack, forming part of the drier. In the truck drier, the rack is on wheels, and the whole may be wheeled in and out of the drier. There may be one or several trucks to each drier, and each truck may have twelve, sixteen or more levels for trays.

C 0.5 M HCl solution and mixes this reaction mixture further °C over the time of 1 h at the same temperature. The reaction mixture further held at room temperature for 24 h, filtered, washed off by 250 cm of distilled water to neutral value of pH and dried in the vacuum drier under the 60 1°C and under pressure 0.9 0.05 kg-cm. Preparation conditions of synthesized samples of PAn and composites shown on Table 1. 

Sweden ulf-mossa Used for wolf poison in Sweden. Pulverized, mixed with fat and flesh, warmed in pan over fire, and them add fresh blood and cheese to create odor. Sometimes mix with powdered glass or strychnine. Put under skin of carcass, wolf will die within 24 h of ingestion. Older, drier lichen is more potent (Withering 1801 Schade 1954)...
