Drum-type coffee surface water air dryer

Abstract

The invention provides a drum-type coffee surface water air dryer which comprises a rack and a rotary drum which is arranged on the rack, the rotary drum is provided with a feeding port and a discharging port, a cavity is provided in the rotary drum and a spiral pushing plate is provided in the cavity. The air dryer is characterized in that a first mesh wall is arranged on the rotary drum, an air pipe connected with an air source is arranged in the cavity of the rotary drum, and a second mesh wall is arranged on the air pipe. According to the invention, when the materials are moved from the feeding port to the discharging port, air drying can be completed at a time, water on the surfaces of the materials can be thoroughly removed, the air drying efficiency is high, the treatment capacity is large, the structure is simple, will not be affected by sites or weather, reliable guarantee can be provided for subsequent material processing, subsequent processing energy consumption is greatly reduced, the processing time is shortened, is conducive to mechanization and automatic processing, and the labor intensity is low.

Description

technical field [0001] The invention relates to an air dryer, in particular to a drum-type coffee surface water air dryer, which belongs to the technical field of design and manufacture of particle surface water removal equipment. Background technique [0002] In order to ensure the quality of coffee and reduce loss, it is usually necessary to carry out the following processing on the picked coffee cherries: impurity removal, fruit sorting, peeling, degumming, and use water for these processing processes, and then dry to remove water. Most of the existing drying is done by cooling, which not only takes up a large space and takes a long time for cooling (generally 12-15 days), but also needs to be turned regularly to ensure uniform drying, which is labor-intensive and more affected by the weather. Large and difficult to control artificially, so that the drying quality cannot be guaranteed. For this reason, many companies invest heavily in drying equipment to dry wet coffee di...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to provide a large-capacity, high-efficiency drum-type coffee table water air-dryer before drying, which fundamentally solves the problem of high energy consumption and high energy consumption caused by directly drying wet coffee in the prior art. The high cost of coffee production affects the economic benefits of enterprises
