Description
技术领域
本发明属于禽畜类中药方剂技术领域,具体涉及清瘟败毒颗粒的制备工艺。
背景技术
“瘟热症”是引起家禽的一种接触性、全身感染性和败血性等多种症状表现的综合性疾病,其临床症状主要是家禽精神沉郁、发热怕冷、张口呼吸、咳嗽、眼肿流泪,拉灰、白、桔红色或烂肉样稀薄粪便、产蛋量下降、产软壳蛋、沙壳蛋、薄壳蛋、白壳蛋等。急性患病家禽可出现精神衰弱,羽毛松乱,头部和颜面浮肿,头、翅下垂,眼睑周围浮肿,肉冠和肉垂肿大,可达正常的3倍以上,出血甚至坏死,鸡冠发紫,关节肿大。目前在临床上较为普遍,大多数地区都有发生,发病的家禽多因脱水、气管衰竭而死,死亡率高,给养殖户造成了巨大的经济损失。
清瘟败毒饮是清代著名温病学家余师愚所创制的名方,载于其所著的《疫疹一得》一书中,后在《中华人民共和国兽药典》收载有“清瘟败毒片”和“清瘟败毒散”。处方由石膏、地黄、水牛角、黄连、栀子、牡丹皮、黄芩、赤芍、玄参、知母、连翘、桔梗、甘草和淡竹叶十四味中药组成,在临床上对畜禽热毒发斑、高热神昏症效果显著。
目前在兽医临床中,该方主要采用散剂,少量使用片剂,如中国专利CN103610977A公开的畜禽用高效清瘟败毒药物的制备方法,该方法为将原料直接粉碎得散剂或粉碎后进一步制备为片剂或粉碎为超微粉剂,保留了原有药物的功效,但在临床实践中发病动物经常出现食欲减退甚至废绝,散剂或片剂拌料使用不佳,还存在散剂适口性不好,家禽消化道短导致中药消化吸收利用度不高,畜禽消化道刺激等不足。
发明内容
为解决现有清瘟败毒药物适口性不好、药物利用率不高的缺点,本发明提供一种清瘟败毒颗粒的制备工艺。
为实现上述目的,本发明采用以下技术方案:

步骤D.将步骤A中的混合细粉、步骤B中的水牛角粉和骤C中的浓缩液与辅料制备成颗粒,即得所述清瘟败毒颗粒。
所述辅料为麦芽糖,所述混合细粉、水牛角粉和浓缩液的总质量与辅料的质量比为1:3。
所述颗粒大小为240~880μm,符合药典:不能通过一号筛(2000um)与能通过五号筛(180um)的总和不得超过15%。
进一步地,所述步骤A、步骤C中原料的重量份为:石膏120份、地黄30份、水牛角60份、黄连20份、栀子30份、牡丹皮20份、黄芩25份、赤芍25份、玄参25份、知母30份、连翘30份、桔梗25份、甘草15份、淡竹叶25份。
进一步地,所述步骤B中加入水的质量与水牛角的质量比为8~12:1,所述煎煮时间为6~9h,所述减压干燥的温度为70℃。
进一步地,所述步骤C中水的质量与粗粉的质量比为8~12:1,超声处理的功率为20kw、时间为50min,所述煎煮时间为1h。
进一步地,所述步骤C中浓缩液的相对密度在室温下为1.2~1.3。
进一步地,所述步骤C中的超声波提取罐,包括承载台和提取罐罐体、下料罐,所述承载台包括第一承载台和第二承载台,第二承载台固定于第一承载台上侧,第二承载台固定提取罐罐体;所述提取罐罐体截面呈“n”字型,提取罐罐体顶部设置有连接到市电的电机,电机连接搅拌桨,所述搅拌桨位于提取罐罐体内部,电机的左侧设置有进料口、右侧安装超声波发生器,提取罐罐体底部连接下料罐;
所述下料罐包括下料罐罐体和活动滤网,下料罐罐体为倒置的上下两端开口的中空圆台,下料罐罐体外侧上部套设有收料槽、下料罐罐体下部连接有液压缸,下料罐罐体顶部设置有密封圈、底部连接下料管,下料罐罐体顶部朝内一侧设置有滑槽,滑槽内连接活动滤网,所述活动滤网中部固定连接搅拌桨、外周活动连接滑槽,活动滤网上环形阵列多个连接杆,所述连接杆铰接活动滤网上下两端,连接杆由第一连接杆和第二连接杆铰接而成。
进一步地,所述第一承载台和第二承载台均由承载台台面和支脚组成,承载台台面是长方形板体,承载台台面的四角处均连接支脚,第二承载台的支脚与第一承载台固定连接,第一承载台的承载台面设置有与下料罐罐体相对应的下料通孔,第二承载台的承载台台面中部设置有圆形通孔,提取罐罐体在圆形通孔内固定。
进一步地,所述提取罐罐体底部设置有与下料罐罐体顶部上的密封圈相对应的密封圈。

进一步地,所述液压缸位于第一承载台下侧,液压缸包括液压缸主体和升降柱,升降柱一端连接液压缸主体、另一端穿过第一承载台连接下料罐罐体。
与现有技术相比,本发明具有以下有益效果:
1.通过本发明制备工艺制备的清瘟败毒颗粒不仅可以采用拌饲料方式,还可以通过饮水的方法对患病动物进行投药,尤其适用于瘟热病动物食欲不佳,饮欲旺盛时饮用,提高了动物的用药适从性。本方法通过超声波提取罐对原料中有效成分进行充分提取,提升畜禽消化利用效率,解决了由于家禽消化道短,对中药散剂消化利用不足等缺点,提高清瘟败毒药物的有效率。
2.本发明中超声波提取罐在完成药物萃取后,萃取液完全经过下料管排出,通过液压缸上的升降柱带动下料罐下降,在下料罐下降的过程中,下料罐上的活动滤网由于连接搅拌桨,活动滤网的连接杆由两端铰接而成,活动滤网会由原来的下凹型变成上凸型,启动连接到市电的电机带动搅拌桨转动,搅拌桨带动活动滤网转动,由于离心作用,活动滤网上的药物残渣进入收料槽内,提高了超声波提取罐的药物残渣的清洁效率。
