Description

Drying oven for continuous operation, especially for drying malt, Grain and the like. The subject of the invention is a drying oven for continuous operation, which is particularly suitable for drying malt, grain and the like. The stove shows a number of drying chambers, which ran through after the series of dry goods will. According to the invention, between the chambers traversed by the dry material adjustable thresholds with inclined contact surfaces arranged to hold the dry goods turn automatically when crossing from one chamber to the next.

The drawing shows an embodiment of the subject matter of the invention shown in longitudinal section.

The brickwork substructure 1 of the furnace carries a number of chambers, eight in the present case, which are designated by 2t to 2v1 ". The chambers are, for example, rectangular, open at the top and separated from one another by adjustable transverse walls 3. The bottom of the chambers is formed by a sieve; l, for example made of wire mesh, which allows the warm dry air access to the dry goods. After the dry air has passed through the goods, it goes outside through the upper, open ends of the chambers. Below the chambers 2, ... is a room, which is divided by fixed transverse walls 7 under the adjustable transverse walls 3 into one of the number of chambers 21 ... the same number of vestibules. The vestibule of each chamber can be connected to the boiler room through closable openings.

Under each baffle 3 is a 1o to 1 5 cm high threshold 6 with an inclined run-on surface on each side.

The drying air is blown by a fan placed outside the oven compressed and passes through a channel 9 in the substructure of the oven. Moving here they have a number of radiators 5, for example steam pipes, around which they are surrounded by partitions to and 11 in snake paths. The radiators can also use the exhaust gases be heated by ovens.

The dry material is first entered into the first chamber 21 and their anteroom is connected to the boiler room, so that the goods are kept warm Air is permeated. After a certain period of time, depending on the type of material to be dried is different, the partition 3 is raised between the first and second chambers or swiveled out and pushed the goods over into the next chamber 211, whereupon the air valve of this chamber is opened. Chamber 2I is now being reloaded etc. until all chambers are filled. Now the oven works continuously, adding in certain Periods of time the completely dried goods are removed from the last chamber and the goods are in the other chambers is pushed forward by one chamber. When moving the Guts is shut off the dry air to save hot air and a nuisance to prevent the operation.

When moving from one chamber to the next, the dry goods are automatically turned by the inclined surface of the sleepers 6 the top layer of the dry material so that it falls to the bottom of the next chamber and to The lower layer on which the previous lower layer is placed as an upper layer. 'In this way, the product becomes complete without any special precautions for mixing and stirring dried.
