         記者：您是如何定義一款好的除濕干燥設備?如何對物料進行干燥才能達到最優的效果?

         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：定義和設計高品質的除濕和干燥設備取決于所選擇的具體的工藝和制造參教。為了達到最優的干燥效果，按照我們常規的程序，首先根據理論和我們大量的工程經驗進行粗略的設計和計算，然后在我們工廠試驗車間的除濕干燥設備上進行樣品側試。在流化干燥工藝工程中取得更為準確的設計數據和產品屬性，進而完善我們的工藝設計參數和設備制造參數。無數的工程案例證明，我公司設計和制造的干燥設備在設計上和使用性能上都能達到讓客戶滿意的效果。

         記者：請您針對傳統除濕干燥設備的性能特點。談談目前市場對除濕干燥設備技術性能的需求。

         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：傳統的除濕干燥設備功能比較單一，能源的綜合利用效能也不高。現代的企業對干燥系統的綜合功能要求越來越高。對環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出多欲性能優越的產品。

        設計和性能是干燥設備的核心部分。我們在設計階段會考慮一系列的而要執行的工藝參數。包括可能影響產品參數控例的各種變量，其次就是通過振動流化床技術進一步優化熱傳遞效果:
         產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品層。流化床的設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，我公司設計和生產的干燥設備還有一個顯著的特征就是方便操作、易于清潔。設備安裝和布局非常人性化。

          記者：對于除濕干燥系統來說，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在檢測控制含水量，進行高效加工上有何獨特優勢?

           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品必須達到非常低的含水率。除濕設備(如內部填充分子篩顆粒的反應物)將與我們干燥系統的氣體供應單元集成在一起。在配備除濕設備的情況下。我們的設備能夠幫助客戶在處理產品時實現恒定和平穩的工藝條件。進而達到最佳和恒定的產品所需要的干燥工藝。
        記者:結晶設備在物料干燥除濕環節中非常重要。貴公司的結晶設備與整體的除濕干燥系統之間如何實現準確檢測，做到高效高質加工?

         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：基于我們在結晶和干燥工藝上長期和大量的工程技術經驗累積，我們能夠設計和生產多種特殊的結構形式以達到最優的工藝控制效果。干燥系統。如流化床配備個性化設計的空氣處理設備將保證更準確地產品流和更優質的產品。

　　記者：貴公司的除濕干燥設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：根據找們的除濕干燥系統在中國和世界范圍內物料行業的眾多應用。我們推薦振動流化床系統作為最有效的干燥或冷卻系統。我們的系統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品處理工藝—干燥/冷卻/結晶/除塵—要求上有更為經濟的選擇。

          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。或其他的熱交換裝置。其熱交換原理是通過產品床與熱交換器底部表面接觸，將產品床中的熱量傳遞給熱交換媒介。此外，我公司生產的所有振動輸送機處理物料都具有溫和、無塵、衛生和氣密性特征。接觸時間是熱交換的重要因素。可以通過精心選擇拋料角、頻率、振動幅度和傾斜角度等參數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產品。可以在螺旋輸送機上下游安裝我們的SRK系列振動篩，這是一款專為塑料顆粒處理而設計的特殊設備。SRK振動篩篩網輕度傾斜，振動電機安裝在兩側，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域而不會出現被豎起來的風險。通過調整振動電機角度優化并適應喂料速度。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備。并簡單介紹該新產品的特點?

           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《如塑料顆粒或類似產品)干燥/冷卻/結晶，微粉化等新系統優化方面做出巨大的努力。與傳統的流化床系統相比，我們的新系統運行更為高效，空氣需求最和廢氣排出最都大為減少。此外。該系統配備了我們開發的特殊輸送系統。運行更為精確。反應時間偏差極小。因此在新系統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。
