油菜籽烘干除杂装置
本专利技术涉及烘干设备
,特别涉及油菜籽烘干除杂装置。
技术介绍
油菜籽也称为芸苔子,是十字花科作物——油菜的果实,成熟的油菜期油菜籽的外壳较长,结荚多,颗粒饱满。油菜籽中油脂的含量为37.5%-46.3%,是中国主要油料作物和蜜源作物之一,同时是制浸油脂原料主要品种之一。油菜在成熟可以收割的时候,由于果壳失水收缩,轻易能够开裂,使得脱壳后的油菜籽中常含有较多的碎壳,需要进行筛分,另外新收的油菜籽由于含水量较大,若没有进行充分的烘干,在储藏的时候容易产生霉变,从而影响油菜籽的质量。现在的油菜籽烘干机,通常包括烘干桶,在烘干桶内设有可旋转的搅拌轴,搅拌轴上设搅拌杆,在进行烘干时,向烘干桶内部通入热气,后驱动搅拌轴转动,使搅拌杆同步转动,从而对油菜籽进行烘干,在烘干后将油菜籽倒入筛分装置进行筛分处理,采用这种处理方式存在以下问题,首先烘干与筛分分开处理,使得油菜籽处理的工艺增加,延长了工艺流程,从而降低了加工的效率;其次,新收的油菜籽通常含水量较高,在烘干过程中,烘干桶内会产生大量水蒸汽,水蒸汽遇烘干桶的桶壁又会重新冷凝,这样使得油菜籽烘干不 ...
