Description
技术领域
本发明涉及采用电磁加热并可对微丸颗粒制剂进行增塑剂与静电干粉结合的干粉包衣的设备,特别涉及一种干粉包衣机。
技术背景
药物包衣常用于固体形态制剂,通过包衣可以掩盖药物散发的不佳气味、防止药物中某些物质见光不稳定或在空气中氧化、控制药物释放部位和释放速度、减少片芯在高速包装设备中破碎以及提高药物外观辨识度的作用。
包衣根据工艺不同,可以分为湿法包衣与干法包衣。目前,基于湿法包衣技术的湿法包衣机被广泛应用在制药工业中对固体药物制剂进行包衣操作。该包衣机工作原理是利用喷雾将包衣液料喷洒到包衣锅内的固体制剂表面,再向固体制剂吹送热风加速固体制剂表面湿液充分挥发,从而让包衣材料均匀包覆于固体制剂表面形成保护层。但是由于湿法包衣技术本身的工艺特点,如需要耗费较长时间对固体制剂进行干燥处理、包衣过程中产生有机溶剂废气废液、有机溶液易燃易爆危险性等,因此湿法包衣机存在耗能、包衣时间长、环境污染等问题。
干法包衣技术近些年来不断发展进步,该方法克服了湿法包衣技术耗能、耗时、环境污染等问题。与湿法包衣技术相比,干法包衣技术不添加有机溶剂,直接将包衣材料在固体制剂表面成膜。干法包衣技术大大缩短包衣时间、节约能源、可以有效避免湿法包衣过程中产生的有机溶剂排放造成的环境污染。现阶段比较常见的干法包衣技术主要有静电干粉包衣技术、采用增塑剂的干法包衣技术和采用增塑剂与静电干粉结合的干法包衣技术。其中最后一种技术将前两者方法相结合,集中二者优点克服前二者缺陷,具有较高的理论研究和市场应用前景。当前国内外市场中适用于制药工业大批量固体制剂包衣加工设备主要还是基于湿法包衣技术,工业应用的干粉包衣机械还鲜有报道。
干粉包衣机由于制造成本高和内部结构复杂等因素,尚处于理论研究阶段。处于该阶段的干粉包衣设备也存在些许不足,譬如:
a)包衣机多采用电热丝或红外线等方式对颗粒制剂加热和干燥,该加热方式热效率低、能耗较大。
b)操作者需手动操控电晕放电喷枪将喷嘴伸入包衣锅内将带电包衣粉末喷向固体制剂表面。由于电晕放电喷枪使用高压电极,喷枪操作者需要近距离观察喷粉情况,具有一定的操作安全隐患。
c)电晕放电喷枪需要操作人员手持瞄准包衣锅内运动的片床进行喷粉操作,在喷粉过程中包衣锅内充斥的带电粉末让操作人员难以清晰观察、瞄准运动的片床来进行有效喷涂,易造成包衣材料浪费,自动化程度较低。
d)采用外置的流化床设计将包衣粉末预先进行静电处理,带电的包衣粉末通过管道输送到包衣锅内可以降低操作者的安全隐患。但流化床设备价格昂贵同时占用大量空间,另外流化床设备需要定期清理维护。当包衣材料改变时,也需要花费较多时间与人力物力对流化床设备和粉末输送管道进行彻底清洁来满足新包衣材料使用需求。
e)包衣锅多采用有孔设计,无法满足较小微丸颗粒包衣,也容易造成包衣材料浪费。
f)包衣机械内部通风较差,若高浓度的干燥包衣粉末颗粒与静电喷枪工作产生的高压静电相遇,有产生粉尘爆炸的风险。
g)包衣锅体常为倾斜放置,倾斜放置的圆柱台状包衣锅会降低包衣过程中其内部颗粒片床表面积、缩短颗粒在片床表层的停留时间,从而降低颗粒上粉效率和包衣层均匀性、延长包衣时间、浪费能源。
针对上述不足,需要研发一种干粉包衣设备,该设备具有结构简单、操作安全、包衣效率高、低能耗,同时能够满足微丸包衣与普通药片包衣的工业化需求。
发明内容
有鉴于此,本发明专利提供一种基于增塑剂与静电干粉结合的干粉包衣设备,该设备具有结构简单、操作安全、包衣效率高、低能耗、可实现微丸或普通药片高效包衣的工业化需求。
