开拓案例五、国际化技术 底部投料

国际先进的乳化分散(凝胶)系统,溶解锅底部出料阀处会出现长晶、乳化时升温速度过长、底部进料时产生物料冲顶现象。生产过程中就要人工开锅,采用手动方式括料,会出现存在残留清不完全、含量不匀、人为微生物带入,数据完整性ALCOA就难以体现正确,都会影响到产品的质量一致性(晶形、结构、含量)。配置国际先进系统,制造出来的产品也不一定是国际一流的。

传统的投粉料方式:锅口进行投入,会在锅壁、搅拌轴等处产生挂粉现象,这部分的粉就不会参与反应或不定期下来,影响到产品质量的一致性(晶形、结构、含量)。

国际化底部投料技术 :底部真空进料,物料直接与锅内液体接触,搅拌溶入,不会出现上锅口投料产生的粉尘飞扬,影响到产品含量质量。

研究底部投料技术对质量一致性 很有必要,结合工业自动化技术,单靠人工控制(数据无法重复)是达不到国际化、实现自动操作是大势所趋:锅内液体不会从底部漏出、粉料又不会冲出液面到锅顶。达到自动控制进料速度,粉料从底部进来,刚好能溶入液体,不能冲锅顶及真空管道等。液体的粘度、比重、温度、搅拌等参数都有关链,通过寻找合适的方案,有的工艺要求进料速度要快又不冲料的高技术。

实现后成果可广泛应用到高端的API、制剂进粉料,提高制造药物质量一致性的产品质量与生产能力。

达到自动控制进料速度,粉料从底部进来,刚好能溶入液体,不能冲锅顶及真空管道的技术实现,PDCA是少不了的,达到国际先进的乳化分散(凝胶)技术也不一件简单的事。

  1. You actually make it seem so easy with your presentation but I find this matter to be actually something which I think I would never understand. It seems too complex and extremely broad for me. I am looking forward , I will try to get the hang of it! Celesta Russ Jami

  2. A great selection of interesting talks, Thank you, I hope all will go well for you. Austin Paulie Hamner
    LAMB的介绍 http://www.niubiquan.com/article/4668?from=groupmessage想0.036元(从0.063开始推的,目前只有1/2了)买入中国版Filecoin主网币,找不到入口的,注册一下康波交易所,就可以屯币了,看看能否爆发? https://www.kangbo.io/#/signup?invitationCode=VHRVQA Filecoin币已冲击600了, LAMB(中国版Filecoin)还在0.05下方,买入可是一个爆发的机会。

  3. Hi there! I discovered your website by way of Google even as looking for a comparable matter, your website came up, It seems to be good. I have bookmarked it in my google bookmarks to visit then. Berrie Natty Gobert

  4. An excellent share, I just offered this onto a colleague that was doing a little evaluation on this. And he actually bought me morning meal because I located it for him. smile. So let me reword that: Thnx for the treat! But yeah Thnkx for spending the time to review this, I feel highly about it and also enjoy finding out more on this topic.
