真空帶式干燥機

VACUUM TAPE TYPE DRIER MACHINE

概 述

真空帶式干燥機是近幾年國內(nèi)發(fā)展起來的一種新型干燥設(shè)備寸士，廣泛適用于絕大多數(shù)天然植物藥的提取物，尤其適合粘性高碴卧、易結(jié)團弱卡、熱塑性、熱敏性的藥物或不適宜于采用噴霧干燥法的物系住册，可連續(xù)進料谐宙、連續(xù)出料。其進料界弧、干燥凡蜻、出料整個過程密閉，在高真空度下進行垢箕，不與外界環(huán)境接觸划栓，符合GMP要求。

在二十世紀50年代条获，真空帶式干燥機首先由德國Merk公司研發(fā)成功忠荞，隨后德國的E&E（易恩）公司、瑞士Bucher公司和日本的大川株式會社也相繼跟上罪焰，經(jīng)過近50年的發(fā)展锌瓤，隨著計算機技術(shù)的快速發(fā)展和應(yīng)用，真空帶式干燥機已經(jīng)成為集光機電一體化的高技術(shù)干燥設(shè)備。

溫州市鴻都輕工機械有限公司由專業(yè)人員赴國外研究考察铝琐，在充分研究了德國的E&E（易恩）公司家漂、瑞士Bucher公司和日本的大川株式會社同類設(shè)備的基礎(chǔ)上，吸取國外的*技術(shù)瑟毡，自主研究開發(fā)了TZ型真空帶式干燥機斯癞。解決了長期以來中藥行業(yè)中許多浸膏難以干燥的問題，采用噴霧干燥溫度高伸果，熱敏性物質(zhì)易被破壞板薛，采用真空烘箱干燥時間長，能耗高刊搁，間斷操作石葫，容易染菌和吸潮，達不到GMP質(zhì)量標準钻局。溫州市鴻都輕工機械有限公司TZ型真空帶式干燥機的研制成功汰寓，對中藥、醫(yī)藥中間體赏淌、精細化工、食品及保健品等行業(yè)的干燥問題起到了極為積極的推動作用啄清，是替代噴霧干燥和真空烘箱干燥的產(chǎn)品六水。如中藥行業(yè)：丹參、復(fù)方丹參辣卒、川芎掷贾、當歸、荣茫、靈芝想帅、苦參、人參啡莉、刺五加等港准；食品保健品行業(yè)：咖啡、麥乳精咧欣、果珍浅缸、速溶奶粉、速溶茶等近沐；還有精細化工庵坛、顏料、農(nóng)藥等行業(yè)都有非常好的應(yīng)用效果象瓤。

TZ型真空帶式干燥機不但干燥溫度低恼睹、可連續(xù)化生產(chǎn)，而且干燥過程損失小叨林、浪費少狞衷、輕松操作剩耸，重要的是降低勞動強度，節(jié)省大量的能源询时。以TZ4型帶式真空連續(xù)干燥機為例谎雷，與同產(chǎn)量真空干燥箱對比，可節(jié)約用電65%捷夜，節(jié)約蒸汽70%楚榕；比同產(chǎn)量的噴霧干燥機節(jié)約用電75%，節(jié)約蒸汽85%非震。

SUMMARY

The vacuum belt type drying machine is a new model drying device developed in recent years in the country. It is widely suitable for extracts of most natural vegetable drugs, and is especially suitable for drugs of high viscosity, drugs that are easy to agglomerate, thermoplastic and heat sensitive drugs, and materials that are inapplicable to the spray drying process. Continuous feeding and discharging can be realized. The whole process of feeding, drying and discharging is carried out under high vacuum without contact with the outside, which conforms to GMP requirements.

In the 1950s, the vacuum belt type drying machine was firstly researched and developed by Germany Merk Company, followed by Germany E&E Company, Switzerlａnd Bucher Company and Japan Okawa Co., Ltd. After nearly 50 years of development, with the rapid development and application of computer technology, the vacuum belt type drying machine has become a high-tech drying device with optical, mechanical and electrical integration.

wenzhou City hongdu Light Industry Co., Ltd. sent professionals to go abroad for research and investigation. On the basis of fully studying the same devices of Germany E&E Company, Switzerlａnd Bucher Company and Japan Okawa Co., Ltd., we have independently researched and developed the TZ model vacuum belt type drying machine by absorbing advanced technology from abroad. The machine has solved the problem of difficult extractum drying existing over a long period of time in traditional Chinese medicine industry. If the spray drying is adopted, the temperature is high and the heat sensitive materials will be easily damaged.

If the vacuum oven is adopted for drying, bacterial contamination and moisture absorption will easily occur because of too long drying time, high energy consumption and intermittent operation, which cannot meet GMP quality standards. The successful research and development of the TZ model vacuum belt type drying machine by wenzhou City hongdu Light Industry Co., Ltd. has played an active role in solving the drying problems in such industries as traditional Chinese medicine, medicine intermediate, fine chemical industry, food, health products and etc. It is an optimal product that replaces the spray drying and vacuum oven drying. It has achieved excellent application effects in many industries. For example: traditional Chinese medicine industry: salvia miltiorrhiza, compound salvia miltiorrhiza, ligusticum wallichii, angelica, andrographis paniculata, ganoderma lucidum, snphora angustifolia, ginseng, acanthopanax root, etc. Food & health products industry: coffee, malted milk, fruit drink, instant milk powder, instant tea, etc. and other industries such as fine chemical industry, pigment, agriculture and etc.

Not only the TZ model vacuum belt type drying machine is featured by low drying temperature, continuous production, low loss during the drying process, few waste and easy operation, but the most important is that it can reduce labor intensity and save large amount of energy. Taking the TZ4 model belt type vacuum continuous drying machine as an example, when compared with the vacuum drying oven of the same output, it can save 65% of electricity and 70% of steam, and when compared with the spray drying machine of the same output, it can save 75% of electricity and 85% of steam.

工作原理：

待干燥的物料通過螺桿計量泵將其送入干燥機的真空室內(nèi)吨拗，并由布料電機均勻的灘涂在傳送帶上。由電機驅(qū)動特制的輥軸傳動傳送帶婿斥，并以設(shè)定的速度運轉(zhuǎn)劝篷。傳送帶下面設(shè)有相互獨立的加熱板和一組冷卻板，傳送帶與加熱板民宿、冷卻板緊密貼合娇妓，以接觸傳熱的方式將干燥所需的熱量傳遞給物料與冷卻。根據(jù)物料性質(zhì)的不同設(shè)定傳送帶的運轉(zhuǎn)速度活鹰，當物料由傳送帶從筒體的一端運送到另一端時哈恰，物料已經(jīng)干燥并冷卻。傳送帶折回時志群，干燥后的料餅從傳送帶上剝離着绷，通過粉碎裝置進行粉碎后，經(jīng)由蝶閥氣閘出料锌云，獲得的顆粒荠医，可直接制成膠囊或壓片。

整臺設(shè)備采用PLC控制桑涎。通過PC機的人機界面來操作設(shè)備彰莲。在干燥機附近設(shè)置觸摸屏操作面板，配置圖形界面烈瘸，能顯示各類工藝參數(shù)聂挚、生產(chǎn)數(shù)據(jù)等參數(shù)，可實時進行修改和調(diào)控犹蝇×庑海可配備CIP在位清洗，使得更換產(chǎn)品清洗非常方便昵斤。
