記者:您是如何定義一款好的除濕干燥設(shè)備?如何對物料進行干燥才能達到最優(yōu)的效果?
Michael Bathon:Definition and design for be in quality of drying equipment chosen by specified process construction data。 In relation to our own experience we will make a first rough design calculation thereafter we will do some feather drying test with a sample of the product at a relevant pilot dryer to get more exact design data and properties of product while fluidized drying process。
夏克俊先生:定義和設(shè)計高品質(zhì)的除濕和干燥設(shè)備取決于所選擇的具體的工藝和制造參教。為了達到最優(yōu)的干燥效果,按照我們常規(guī)的程序,首先根據(jù)理論和我們大量的工程經(jīng)驗進行粗略的設(shè)計和計算,然后在我們工廠試驗車間的除濕干燥設(shè)備上進行樣品側(cè)試。在流化干燥工藝工程中取得更為準確的設(shè)計數(shù)據(jù)和產(chǎn)品屬性,進而完善我們的工藝設(shè)計參數(shù)和設(shè)備制造參數(shù)。無數(shù)的工程案例證明,我公司設(shè)計和制造的干燥設(shè)備在設(shè)計上和使用性能上都能達到讓客戶滿意的效果。
記者:請您針對傳統(tǒng)除濕干燥設(shè)備的性能特點。談談目前市場對除濕干燥設(shè)備技術(shù)性能的需求。
Michael Bathon: As a main aspect design and performance of our drying equipment will fulfill required process data incl。 a wide range of possible variation to control the data of the product。 Further an optimum heat transfer is achieved in vibratory fluidized bed dryer/coolers。 The drying or cooling medium evenly penetrates the product bed which is being conveyed across the perforated sieve。 The large heat exchange area in the fluidized bed provides a rapid heat transfer between solid particles and gas。 Our drying equipment also will be designed in accordance to easiest handling while cleaning purposes adapted to operators installation location。
夏克俊先生:傳統(tǒng)的除濕干燥設(shè)備功能比較單一,能源的綜合利用效能也不高。現(xiàn)代的企業(yè)對干燥系統(tǒng)的綜合功能要求越來越高。對環(huán)保運行和人性化操作也越來越重視。我公司長期以來緊眼市場的需求,與客戶密切合作開發(fā)出多欲性能優(yōu)越的產(chǎn)品。
設(shè)計和性能是干燥設(shè)備的核心部分。我們在設(shè)計階段會考慮一系列的而要執(zhí)行的工藝參數(shù)。包括可能影響產(chǎn)品參數(shù)控例的各種變量,其次就是通過振動流化床技術(shù)進一步優(yōu)化熱傳遞效果:
產(chǎn)品在流化板上被輸送的同時,干燥或冷卻媒介均勻的透過產(chǎn)品層。流化床的設(shè)計為固體顆粒和氣體之間的熱傳遞提供了更大的交換空間。此外,我公司設(shè)計和生產(chǎn)的干燥設(shè)備還有一個顯著的特征就是方便操作、易于清潔。設(shè)備安裝和布局非常人性化。
記者:對于除濕干燥系統(tǒng)來說,分子篩水含量的加工直接影響著物料加工效果,貴公司的除濕干燥系統(tǒng)在檢測控制含水量,進行高效加工上有何獨特優(yōu)勢?
Michael Bathon:Dehumidifying equipment (e.g.filled by reactive material ofmolecular sieve particles) will be integrated in air supply equipment of our drying systems if process data should get a very low final moisture。 In case of operating with a dehumidifier our customer will get the advantage to handle his product under constant and even well process conditions。 This result in best and 22915 stant production for the drying process。
夏克俊先生:如果工藝要求最終產(chǎn)品必須達到非常低的含水率。除濕設(shè)備(如內(nèi)部填充分子篩顆粒的反應物)將與我們干燥系統(tǒng)的氣體供應單元集成在一起。在配備除濕設(shè)備的情況下。我們的設(shè)備能夠幫助客戶在處理產(chǎn)品時實現(xiàn)恒定和平穩(wěn)的工藝條件。進而達到最佳和恒定的產(chǎn)品所需要的干燥工藝。
記者:結(jié)晶設(shè)備在物料干燥除濕環(huán)節(jié)中非常重要。貴公司的結(jié)晶設(shè)備與整體的除濕干燥系統(tǒng)之間如何實現(xiàn)準確檢測,做到高效高質(zhì)加工?
Michael Bathon: Back to our great experiences in crystallization and drying processes we are able to design and to manufacture it with special construction
to perform an optimized process control。 Drying systems like f uidized bed provided with best possible customized air handling equipment will ensure a high accuracy of product flow and quality。
夏克俊先生:基于我們在結(jié)晶和干燥工藝上長期和大量的工程技術(shù)經(jīng)驗累積,我們能夠設(shè)計和生產(chǎn)多種特殊的結(jié)構(gòu)形式以達到最優(yōu)的工藝控制效果。干燥系統(tǒng)。如流化床配備個性化設(shè)計的空氣處理設(shè)備將保證更準確地產(chǎn)品流和更優(yōu)質(zhì)的產(chǎn)品。
記者:貴公司的除濕干燥設(shè)備是采用哪種方式對物料進行干燥的?更適用于哪種物料的干燥?
Michael Bathon:For many applications in China and worldwide plastic industries we recommend to use our Vibratory Fluidbed system as a most efficient drying or cooling system。 Our systems like Vibratory Screen Dryer series VSK, Vibratory Fluidbcd Dryer/ Cooler series VF or dVW, Natural frequency Fluidbed dryers series VR as well as our Static Fluidbed dryer series SF will provide a lot of possibilities and also gives the opportunity to choose for best economical way of drying/cooling/ crystaWang/de-dusting the various kind of plastic products of our customer。
As a suitable addition to above described type of machines also our Trough, Tube and Spiral Conveyors are equipped for this purpose either with heat exchangers for cooling water, steam m t ermal ail or with other heat transfer devices。 The beat exchange principle is as follows: Heat is transferred from the product bed via the contact surface of the heat exchanger bottom to the heat transfer medium。 Over and above that all our Vibrating Conveyors facilitate gentle,dust-free, hygienic and gaslight handling of the bulk material。 The contact time,which is important to the heat transfer,can be adapted to individual operating requirements through careful selection of the angle of throw, frequency, vibration amplitude and inclination。 In many respects, spiral conveyors are similar to horizontal trough conveyors。 The great advantage of spiral conveyors, however, is that they permit a large exchange surface to be achieved over a small floor space,with a long path and a correspondingly long residence time。 At the end and to safe high quality of product we often offer our Vibratory Separators Type SRK, which are specially designed for operating with plastic pellets。 SRI{ screening machines have a slightly inclined screen and motor vibrators mounted laterally at a small angle of throw。 Screening can therefore take place with a very low vertical acceleration, ensuring that over length particles contained in the feed are conveyed flat across to the screen area without the risk of uprighting。 The motor vibrators can be adjusted through a given angle for optimum adaptation to the feed rate。
Finally the screening efficiency depends on the ratio of hole width versus particle size。
夏克俊先生:根據(jù)找們的除濕干燥系統(tǒng)在中國和世界范圍內(nèi)物料行業(yè)的眾多應用。我們推薦振動流化床系統(tǒng)作為最有效的干燥或冷卻系統(tǒng)。我們的系統(tǒng)如振動篩分干燥機系列VSK、振動流化床干燥機/冷卻機系列VF或DVW、共振流化床干燥機系列VR,以及靜態(tài)流化床系列SF提供了多種選擇;同時也為我們的廣大客戶在多種物料產(chǎn)品處理工藝—干燥/冷卻/結(jié)晶/除塵—要求上有更為經(jīng)濟的選擇。
除了流化床干燥機。我們還有非常適合除濕干燥功能的其他設(shè)備,如指式、管式和螺旋輸送機,采用冷卻水、蒸汽或熱煤油等作為熱交換介質(zhì)?;蚱渌臒峤粨Q裝置。其熱交換原理是通過產(chǎn)品床與熱交換器底部表面接觸,將產(chǎn)品床中的熱量傳遞給熱交換媒介。此外,我公司生產(chǎn)的所有振動輸送機處理物料都具有溫和、無塵、衛(wèi)生和氣密性特征。接觸時間是熱交換的重要因素??梢酝ㄟ^精心選擇拋料角、頻率、振動幅度和傾斜角度等參數(shù)滿足具體的工藝操作要求。
在很多方面螺旋輸送機同水平式輸送機相似。螺旋輸送機的最大特點就是占用很小的樓面面積,達到最大的熱交換面積。為了達到更安全的高品質(zhì)產(chǎn)品??梢栽诼菪斔蜋C上下游安裝我們的SRK系列振動篩,這是一款專為塑料顆粒處理而設(shè)計的特殊設(shè)備。SRK振動篩篩網(wǎng)輕度傾斜,振動電機安裝在兩側(cè),拋料角度較小;所以只要很低的垂直加速度就能篩分,保證了進料中所含的較長顆粒能夠平躺著滑過輸送區(qū)域而不會出現(xiàn)被豎起來的風險。通過調(diào)整振動電機角度優(yōu)化并適應喂料速度。最終的篩分效率還要取決于塑料粒徑和篩孔寬度的比率。
記者:近期貴公司推出了哪些新的除濕干燥設(shè)備。并簡單介紹該新產(chǎn)品的特點?
Michael Bathon:Next time we will take a lot of our effort to optimize our new system for drying/cooling/crystallizing/powdering of bulk materials like plastic pellets or similar products。
In opposite to classical/traditional Fluidbed systems our new system will operate very effective with much lower quantity of air supply and exhaust air flow rate。 Further it will be able to operate with a high accuracy, means a very tight deviation of the residence time by using our special developed conveying mechanism, so at the end all single particles of any bulk material will remain to nearly the same time inside of this new developed system。
夏克俊先生:在近年來,我公司在散料《如塑料顆?;蝾愃飘a(chǎn)品)干燥/冷卻/結(jié)晶,微粉化等新系統(tǒng)優(yōu)化方面做出巨大的努力。與傳統(tǒng)的流化床系統(tǒng)相比,我們的新系統(tǒng)運行更為高效,空氣需求最和廢氣排出最都大為減少。此外。該系統(tǒng)配備了我們開發(fā)的特殊輸送系統(tǒng)。運行更為精確。反應時間偏差極小。因此在新系統(tǒng)中處理過的所有散料,其每一個顆粒的反應時間幾乎都是相同的。
