Description

一种雾化盘、喷雾干燥雾化器及其雾化高粘度物料的方法 技术领域
本发明涉及喷雾干燥领域，尤其涉及一种雾化盘、喷雾干燥雾化器及其雾化高粘度物料的方法。
背景技术
微胶囊化技术是指将固体、液体或者气体包埋在微小而密封的胶囊中，使其只在特定条件下控制释放的技术，其中被包埋的物质称为芯材，如维生素系列，包埋芯材实现微胶囊化的物质称为壁材，如明胶、葡萄糖，蔗糖等。微胶囊化方法分为化学法、物理化学法和物理法，根据需要选择，喷雾干燥法是目前最常用和成本最低廉的微胶囊方法，制备工艺为：先将芯材分散在液化的壁材中，称乳化，然后进行喷雾造粒和干燥。为达到更好的微胶囊化收率要求微胶囊化的乳液水含量尽量少，微胶囊的颗粒尽量均匀，尽量减少小颗粒。目前行业内喷雾干燥常用的雾化方法有：高速离心雾化(最高粘度400cp)、压力喷雾(最高粘度500cp)、气流雾化(最高粘度600cp)。当雾化的物料为高粘度(粘度值为400cp～2250cp)物料时这三种雾化方法无法取得满意的雾化效果，且上述三种雾化方法得到微粒的粒径分布都很宽。
发明内容
本发明的目的在于提供一种雾化盘、喷雾干燥雾化器及其雾化高粘度物料的方法，以使用喷雾干燥工艺雾化高粘度物料时取得颗粒粒径分布窄的粉体。
为实现上述目的，本发明提供喷雾干燥雾化器的雾化盘，其特征在于，所述雾化盘为上部大下部小的倒锥形状的圆台，圆台内空，雾化盘的侧壁有倒锥孔(10)，倒锥孔(10)在雾化盘里侧的那头的直径大，在雾化盘外侧的那头的直径小；雾化盘的侧壁与圆台的上水平面的夹角为锐角。
进一步，所述倒锥孔(10)在雾化盘里侧的那头的直径不大于1mm，在雾化盘外侧的那头的直径为100～450μm；
任选的，所述雾化盘的侧壁与圆台的上水平面的夹角为30°～90°，不含90°；
任选的，所述倒锥孔的内表面光滑。
另一方面，本发明还提供一种喷雾干燥雾化器，其特征在于，包含所述雾化盘。
进一步，还包括导风系统、进料系统、传动装置。
进一步，所述导风系统包括导风管(1)和导流槽(4)，导流槽(4)中设置多个角度可调节的导流叶片，通过导风管(1)进来的导流风输送到导流槽(4)，通过导流槽(4)导流成旋状风进入干燥塔。
进一步，所述传动装置包括电机(3)、传动带(6)和转动轴(9)，所述转动轴(9)是中空的，转动轴(9)在电机(3)和传动带(6)的传动下转动，转动轴(9)再带动雾化盘(7)转动；转动轴(9)的下端与雾化盘连接，上端通过端面密封(5)与进料管(2)连接，形成进料系统。端面密封相接，确保物料不发生泄露。
进一步，所述导流叶片的垂直夹角角度为3-30度，相邻的两块导流叶片在垂直方向的投影应有部分重叠。
进一步，还包括基座(8)。
另一方面，本发明还提供一种雾化高粘度物料的方法，其特征在于，使用了所述的喷雾干燥雾化器。
进一步，高粘度物料通过进料管(2)打入到雾化盘(7)中，高粘度物料随着雾化盘(7)的转动一起转动并通过雾化盘(7)上的倒锥孔被分散成均匀的雾滴，该均匀的雾滴被从导流槽(4)出来的旋状风旋进干燥塔进行干燥从而得到颗粒；
优选的，所述高粘度物料的粘度为400cp～2250cp。具体地处理方案为：高粘度的物料通过进料管打入到雾化盘中，高粘度的物料与雾化盘一起转动并通过雾化盘的小锥孔被分散成均匀的颗粒，由于雾化盘的侧壁打满微小的倒锥孔，高粘度的物料在离心力的作用下透过该倒锥孔，由于倒锥孔小且均匀，能形成的均匀的雾滴。导流风由管道输送到导流槽，通过导流槽时被导流槽中的导流叶片导流成旋状风。通过雾化盘的均匀料液颗粒被出导流槽的旋风旋进干燥塔进行干燥。该雾化器不仅解决了高粘度物料的雾化问题，得到的雾化颗粒粒径具有很窄的粒径分布，而且解决了喷雾塔塔顶雾化器四周的物料粘壁问题。
