The drying body is installed on the frame through elastic elements. During the drying process, it keeps beating, so it is heated evenly and the drying effect is good.

Description

Lifting Dryer

Technical field

The utility model belongs to a drying device, in particular to a lifting dryer suitable for drying agricultural products.

Background technique

There are many types of agricultural product drying equipment in the prior art, such as tower dryers, fluidized bed dryers, belt dryers and the like. Among them, the tower dryer is the most widely used. The tower dryer uses hot air as the heat source, and the hot air dries the material during the flow. According to the flow direction of the hot air and the material, the tower dryer is divided into downstream drying, countercurrent drying or mixed flow drying. The tower dryer adopts a building block metal structure, which is mainly composed of a primary drying section, a slowing section, a secondary drying section, and a cooling section. The primary and secondary drying sections are respectively connected to the hot stove through pipelines, and the cooling section is connected to the fan through pipelines. The material moves from top to bottom between the partitions in the dryer, exchanges heat with the hot air, and discharges the water in it. The main problems of this kind of dryer are: complex structure, bulky, high cost, and large investment cost. Moreover, the tower dryer is only suitable for drying bulk grains, and is not suitable for use in conjunction with other equipment on the production line. It is generally used in large-scale national grain reserves and is not suitable for ordinary agricultural product processing enterprises.

Contents of Invention

The purpose of this utility model is to overcome the problems existing in the above-mentioned prior art, and to provide a lifting dryer with simple structure, small size, low price, and suitable for use with other equipment on the production line.

The utility model has a frame, on which a heat preservation cover is installed, and a hot air pipe connected with a heat source is arranged under the heat preservation cover. It is composed of an inner cylinder, a spiral coaming and a spiral piece. The spiral piece is located between the inner cylinder and the spiral coaming. The upper and lower ends of the inner cylinder are closed, and the lower end is connected with the hot air pipe. The air jet hole is equipped with a vibration device on the drying main body, and the drying main body is installed on the frame through elastic elements.

The utility model has the advantages of simple structure, small size, small floor space and low cost, and is suitable for use in conjunction with other equipment on the production line; in addition, the utility model uses vibration to convey materials from bottom to top, and the materials are dried In the process of continuous beating, so the surface is heated evenly and the drying effect is good.
