Abstract

本实用新型属于粮食烘干设备技术领域，涉及一种粮食烘干机的双层干燥装置，包括烘干塔，所述烘干塔从下至下依次设有一次烘干段、一次缓苏段、二次烘干段和二次缓苏段，所述一次缓苏段、二次烘干段之间设有一根横向贯穿所述烘干炉的热风管，所述热风管一端装有热风机。本装置结构简单，合理，可使烘干介质(热空气)由烘干塔体中部进入烘干塔内，分别向烘干塔上下两端流动进行烘干，粮食在一次烘干段经过一次缓速烘干后，进入二次烘干段后又得到二次烘干，实现粮食一次循环两次烘干的效果，减少粮食在储留部中的流动时间，达到更高的烘干效率。

Description

粮食烘干机的双层干燥装置
【技术领域】
本实用新型属于粮食烘干设备技术领域，涉及一种粮食烘干机的双层干燥装置。 
【背景技术】
在本装置作出以前，在已有的烘干机中，粮食通过干燥部上层的储留部，进入干燥部及下本体中进行干燥，再进行循环干燥。这种结构的干燥机在经过储留部进入干燥部的过程中，由于粮食在储留部中的流动时间过长，造成烘干时间的浪费，烘干效率低下。 
【实用新型内容】
本实用新型所要解决的技术问题在于提供一种粮食烘干机的双层干燥装置，只需一台热风机，就使粮食经过一次缓速烘干后，更加快速的进行二次烘干，提高粮食的烘干速度。 
本实用新型的技术方案是：粮食烘干机的双层干燥装置，包括烘干塔，所述烘干塔从上至下依次设有一次烘干段、一次缓苏段、二次烘干段和二次缓苏段，所述一次缓苏段、二次烘干段之间设有一根横向贯穿所述烘干炉的热风管，所述热风管一端装有热风机。 
本实用新型的优点在于：本装置结构简单合理，可使烘干介质(热空气)由烘干塔体中部进入烘干塔内，分别向烘干塔上下两端流动进行烘干，粮食在一次烘干段经过一次缓速烘干后，进入二次烘干段后又得到二次烘干，实现粮食一次循环两次烘干的效果，减少粮食在储留部中的流动时间，达到更高的烘干效率。 
【附图说明】
下面参照附图结合实施例对本实用新型作进一步的描述。 
图1为本实用新型的结构示意图。 
【具体实施方式】
参见图1，粮食烘干机的双层干燥装置，包括烘干塔，所述烘干塔从上 至下依次设有一次烘干段1、一次缓苏段2、二次烘干段3和二次缓苏段4，一次缓苏段2、二次烘干段3之间设有热风管5，热风管5一端装有热风机6，另一端可以与二次缓苏段4底部空腔连通，形成循环热风，这样热风可以从二次缓苏段4底部空腔进入二次烘干段3，提高热量的利用率。 
工作时，热风机6将热风吹入热风管5，从烘干塔中部进入，热风同时进入一次烘干段和二次烘干段。粮食经过上层缓苏段进入一次烘干段进行干燥，然后在经过一次缓苏段进入二次烘干段进行二次干燥。这样，粮食一次循环，可经历两次干燥过程，两次缓苏过程。 
粮食在进入一次烘干段及缓苏段后，粮食原始的表层水分及转移到表层的水分逐次被蒸发，温度向粮粒内部扩散，粮粒内部水分向外转移之后，进入二次烘干段及缓苏段，粮粒之间和粮粒内外部之间的温度和湿度梯度进一步达到均衡一致，可以使粮食内部水分充分扩散，保证了粮食的品质。 
尽管已经示出和描述了本实用新型的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本实用新型的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本实用新型的范围由所附权利要求及其等同物限定。
