Low-temperature mixed flow circulation peanut dryer and drying method thereof

Abstract

The invention relates to a low-temperature mixed flow circulation peanut dryer and a drying method thereof in the technical field of agricultural machinery. The peanut dryer comprises a feeding mechanism, a material circulation conveying system, a main bin and a material drying system, wherein the material circulation conveying system comprises a base assembly, a lifting mechanism, a discharge pipe, an upper conveyor, a grain storage room and a drying room arranged in sequence; the material drying system comprises an air inlet duct and an air exhausting duct, the material drying system furthercomprises a plurality of layers of air inlet strip-shaped boxes and a plurality of layers of air outlet strip-shaped boxes arranged in the drying room up and down alternately, a plurality of air inlets in communication with the air inlet strip-shaped boxes are formed in the side wall of the air inlet duct, a plurality of air outlets in communication with the air outlet strip-shaped boxes are formed in the side wall of the air exhausting duct, heating parts are arranged in the inlets of the air inlet duct, and centrifugal fans are arranged in the outlets of the exhausting duct; and during drying, the heating parts heat the air inlet duct, the centrifugal fan can discharge hot and humid airflow in the drying room, fast, efficient, uniform, low consumption and dried drying requirements can be well met, and the machine and method are suitable for peanuts as the characteristics of the peanuts are taken into account.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to peanut drying technology. Background technique [0002] In recent years, with the rapid advancement of large-scale planting and mechanized harvesting technology, peanut harvesting has become more and more concentrated. The original drying facilities and labor resources in the field can no longer meet the needs of post-production peanut rapid drying. Therefore, it is necessary to provide a peanut mixed-flow circulation dryer suitable for fast, efficient, uniform, and low-consumption drying in peanut production that meets the characteristics of peanut materials. Contents of the invention [0003] The purpose of the present invention is to provide a low-temperature mixed-flow circulation peanut dryer and its drying method, which can well meet the requirements of fast, efficient, uniform, and low-consumption drying of peanut materials, and meet the characteristics of...
