Embodiment Construction

[0053] Embodiments of the invention

[0054] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 to Figure 8 It is the drying device 1 of the first embodiment. In the figure, 4 is a cylindrical drying tank, and its cylindrical inner wall is the heat transfer surface 2 of the drying device, and its function is to transfer the heat supplied by the heat transfer equipment to the object 3 to be dried. The above-mentioned heat transfer equipment refers to the jacket 6 located around the drying tank 4 and the boiler (not shown) connected to the jacket to send steam 7 to the jacket 6 . In addition, the jacket 6 is provided with a steam introduction part 11 for introducing the steam 7 into the jacket 6 and a steam discharge part 12 for discharging the steam 7 out of the jacket 6 .

[0055] The side wall at the bottom 4a of the above-mentioned drying tank 4 is connected with a dried material supply pipe 13, and the dried ma...

Abstract

The present invention provides a drying device of high drying efficiency by effectively using the whole heat transfer face without retention and biting of a dried object. In this drying device (1), a rotary winding blade (5) composed of a plurality of base blades (5a) is installed rotatably around a rotating shaft (5b) in a drying tank (4) formed with a heat transfer face (2). Each base blade (5a) has a flat face (8) of elongate shape extending obliquely upward from one end part (18) toward the other end part (19) in a reverse direction to a rotating direction R, and a clearance U is formed between an outer peripheral end 10a and the heat transfer face (2). The clearance U is formed to be gradually larger in the reverse direction to the rotating direction. One end part (18) of the flat face (8) is continuous with a scraping plate (20), and a projecting part (21) is provided in the rotating direction R from the outermost end part of the scraping plate (20).

Description

technical field [0001] The invention relates to a drying device which pushes the object to be dried to the heat transfer surface while rolling up the object to achieve the drying effect. Background technique [0002] As we all know, there are many kinds of drying equipment for drying liquid, fluid, semi-fluid or powder, granular and other dried objects. [0003] For example, the present applicant previously disclosed the drying apparatuses in the publications such as JP-3-19501 and JP-5-64692. This drying device consists of a cylindrical drying tank used to put in the dried object, a cylindrical drying tank inner wall heat transfer surface that transfers the heat source to the dried object, and a heat transfer surface located around the drying tank. The heat-supplying heat transfer equipment and a vertical helical rotating blade which is arranged in the above-mentioned drying tank and can rotate is composed of a plane that can make the dried object rise after being loaded. ...
