摘要/Abstract

摘要： 随着作物种植规模的扩大和机械化收获方式的普及，作物收获效率大幅度提高。传统人工晾晒效率较低，已不适合现代化农业生产，粮食机械化干燥是作物产后加工的重要发展方向。混流干燥机作为使用最广泛的干燥机，得到了广泛关注。阐述混流干燥机的干燥原理及结构组成，从关键部件设计、控制系统研究和辅助研究手段三方面对比国内外混流干燥机的研究现状，介绍混流干燥机的能源配置与现阶段混流干燥机主要存在设备通用性较差、自动化监测、监控组件落后、仿真试验结果不准确、干燥过程灰尘较大和机艺不融合等问题。从提高设备通用性、开发自动化监测、监控组件、提高建模精度、设计研发相关的除尘设备和机艺融合方面对混流烘干机进行展望。

Abstract: Crop harvesting efficiency has improved dramatically with the expansion of the crop planting scale and the popularization of mechanized harvesting methods. Grain mechanized drying is a significant development direction of postpartum crop processing. The traditional artificial drying efficiency is low and unsuitable for modern agricultural production. The mixedflow dryer has attracted extensive attention as the most widely used dryer. This paper expounds on the working principle and structural composition of the mixedflow dryer and compares the research status at home and abroad from three aspects: key component design, control system research, and auxiliary research means. This paper introduces the energy configuration of the mixedflow dryer and the main problems of the dryer, such as poor equipment universality, low degree of automation, inaccurate simulation test results, large dust in the drying process, and nonintegrated machine technology. The mixedflow dryer is prospected by improving equipment universality, developing automatic monitoring and monitoring components, improving modeling accuracy, designing and developing relevant dust removal equipment, and mechanical technology integration.

Key words: mixed flow dryer, angular tube, flow uniformity, drying quality
