Description

一种微粒类物料生产过程中的水分离除杂工艺
技术领域
本发明涉及微粒类物料的加工方法领域,尤其涉及一种微粒类物料生产过程中的水分离除杂工艺。
背景技术
灵芝孢子、花粉等微粒类物料的收集、采集过程中会混入很多灰尘杂质,再加上自身有一些空瘪粒,造成产品纯度不够高,传统加工过程对物料前处理一般采用过筛法,利用不同规格的筛网过滤掉杂质。
但是筛分法只能去除肉眼明显可见的树叶或大粒径砂子等杂质,灰尘以及空瘪粒的粒径与孢子、花粉得微粒类物料相当,甚至更小,且粘附力强,很难去除,因此传统筛分法处理的灵芝孢子、花粉等物料中的灰尘杂质依然很多。
发明内容
本发明的目的在于克服现有技术的不足,提供了一种微粒类物料生产过程中的水分离除杂工艺,使得孢子、花粉等微粒类物料的纯度大幅度提高。
本发明通过以下技术方案实现:一种微粒类物料生产过程中的水分离除杂工艺,包括以下工艺步骤:S1.将微粒类物料分散于常温水中,并加入第一悬浮罐中,搅拌10~18min,然后沉降10~20min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降10~20min;S3.用泵将沉降后的悬浊液中层液体抽出,并通入超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持10~20min;S5.用泵将中层液体抽出并通入离心脱水机中脱水,离心所得固形物经常温鼓风干燥6~8h,最后在微波负压真空干燥箱中烘干得成品。
优选的,步骤S1中,微粒与水的质量份数比为1∶120~170。
优选的,所述超声波振动筛的筛网目数为200~400目。
优选的,所述微粒类物料为灵芝孢子或花粉。
优选的,微粒类物料生产过程中的水分离除杂工艺包括以下工艺步骤:S1.将灵芝孢子或花粉微粒类物料分散于常温水中,其中微粒与水的质量份数比为1∶140~160,并加入第一悬浮罐中,搅拌13~18min,然后沉降15~20min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降10~15min;S3.用泵将沉降后的悬浊液中层液体抽出,通入筛网目数为200~400目的超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持10~20min;S5.用泵将中层液体抽出并通入离心脱水机中脱水,离心所得固形物经常温鼓风干燥6~8h,最后在微波负压真空干燥箱中烘干得成品。
优选的,微粒类物料生产过程中的水分离除杂工艺包括以下工艺步骤:S1.将灵芝孢子或花粉微粒类物料分散于常温水中,其中微粒与水的质量份数比为1∶150,并加入第一悬浮罐中,搅拌15min,然后沉降20min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降10min;S3.用泵将沉降后的悬浊液中层液体抽出,并通入筛网目数为300目的超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持10min;S5.用泵将中层液体抽出并通入离心机脱水机中脱水,离心所得固形物经常温鼓风干燥6h,最后在微波负压真空干燥箱中烘干得成品。
本发明的有益效果在于,对微粒类物料中的灰尘、空瘪粒以及其他杂质的去除效果显著,工艺方法简单,易于实施。根据实验数据,可将孢子、花粉等微粒类物料的纯度提高20%以上,大大提高产品质量,增加产品使用效率。
附图说明
图1是本发明微粒类物料的除杂工艺的流程图。
具体实施方式
下面,结合附图1通过具体实施例对本发明的技术方案进行详细说明。
实施例1
参阅图1,包括以下工艺步骤:S1.将灵芝孢子或花粉微粒类物料分散于常温水中,其中微粒与水的质量份数比为1∶150,并加入第一悬浮罐中,搅拌15min,然后沉降20min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降10min;S3.用泵将沉降后的悬浊液中层液体抽出,并通入筛网目数为300目的超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持10min;S5.用泵将中层液体抽出并通入离心机脱水机中脱水,离心所得固形物经常温鼓风干燥6h,最后在微波负压真空干燥箱中烘干得成品。
其中,搅拌机转速1420rpm,超声振动筛工艺参数:超声频率36kHz,离心机转鼓转速850rpm。
实施例2
参阅图1,包括以下工艺步骤:S1.将微粒类物料分散于常温水中,其中微粒与水的质量份数比为1∶170,并加入第一悬浮罐中,搅拌10min,然后沉降15min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降15min;S3.用泵将沉降后的悬浊液中层液体抽出,并通入筛网目数为200目的超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持15min;S5.用泵将中层液体抽出并通入离心机脱水机中脱水,离心所得固形物经常温鼓风干燥8h,最后在微波负压真空干燥箱中烘干得成品。
其中,搅拌机转速1520rpm,超声振动筛工艺参数:超声频率36kHz,离心机转鼓转速850rpm。
实施例3
参阅图1,包括以下工艺步骤:S1.将微粒类物料分散于常温水中,其中微粒与水的质量份数比为1∶130,并加入悬浮罐中,搅拌18min,然后沉降10min;S2.用泵将沉降后的悬浊液中层液体抽出,通入第二悬浮罐中,沉降20min;S3.用泵将沉降后的悬浊液中层液体抽出,并通入筛网目数为400目的超声波振动筛中超声过滤;S4.经超声波振动筛过滤所得液体通入第三悬浮罐中,保持18min;S5.用泵将中层液体抽出并通入离心机脱水机中脱水,离心所得固形物经常温鼓风干燥7h,最后在微波负压真空干燥箱中烘干得成品。
其中,搅拌机转速1320rpm,超声振动筛工艺参数:超声频率36kHz,离心机转鼓转速850rpm。
本发明以水为媒介,将灵芝孢子或花粉等微粒类物料分散于水中,根据泥土沙尘的比重大于物料(正常孢子或花粉),可用沉淀法淘去泥土沙尘;根据腐植质尘埃和发育不良的空瘪孢子和花粉比重小于物料(正常孢子或花粉),可用捞去漂浮物法去除;根据孢子、花粉形态呈规则性椭圆形(体外光滑)和径粒大小规则比较容易从超声波振动筛的滤网筛孔中“漏”过,而同等径粒的尘埃杂质却形态不规格、外表毛糙,多边角呈“刺”状不规则,极易被拌挂在滤网筛孔上,但经一定频率的脉冲使筛网孔丝颤抖,被绊住在筛孔的杂质又会“跳”起来,如此循环多次为形态椭圆规则、外表光滑的孢子或花粉顺利通过滤网筛孔提供了充足的机会。根据实验数据,本发明的工艺过程可将孢子、花粉等微粒类物料的纯度提高20%以上。
以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,根据本发明的技术方案及其发明构思加以等同替换或改变,都应涵盖在本发明的保护范围之内。
