Abstract

The invention discloses an air flow drying device with a double helix structure. The air flow drying device comprises an outer drying drum and an inner drying drum. The outer drying drum comprises an outer drum body, a top cover and a drum base, wherein the upper end and the lower end of the outer drum body are provided with openings, the top cover is fixedly connected to the upper end of the outer drum body and seals the opening at the upper end of the outer drum body, and the drum base is fixedly connected to the lower end of the outer drum body and seals the opening at the lower end of the outer drum body. The upper portion of a side wall of the outer drum body is provided with a feeding port penetrating the side wall, the upper end and the lower end of the inner drying drum are provided with openings, the inner drying drum and the outer drum body are coaxial, the opening at the lower end of the inner drying drum is arranged in the outer drum body, the opening at the upper end of the inner drying drum penetrates the top cover, a spiral downward guide plate is arranged in an area between an inner wall of the outer drum body and an outer wall of the inner drying drum, and an inner wall of the inner drying drum is provided with a spiral upward groove. The air flow drying device overcomes the shortcomings of an existing air flow dryer, the height of the device is reduced, the retention time of materials in the dryer is prolonged, and the air flow drying device has the advantages of being good in drying performance, convenient to operate, small in size and low in cost.

Description

technical field [0001] The invention relates to the field of airflow dryers, in particular to airflow drying equipment with a double helix structure. Background technique [0002] The airflow dryer has the advantages of high drying strength, large processing capacity, and simple equipment, and has been widely used in the pharmaceutical, food, and chemical industries.
