的詳細介紹

隨著真空干燥技術(shù)不斷進步，在真空條件下控制溫度對樣品進行干燥的方法也越來越受到重視，與常規(guī)干燥法相比所具有的優(yōu)勢如下：

1.	the vacuum environment greatly reduced the liquid boiling point which needs to drive out,therefore the vacuum is dry may with ease apply to heat sensitivity material
2.	for the sample that does not be dry easily,such as powder or other pellet form sample,using vacuum dry method may efficiently shorten dry time.
3.	various structures are complex the or other porous sample process of machinery ministry uses vacuum dry function after washing,have no any remnant quality after being dry compley.
4.	use more safety-under vacuum or inertia condition,eliminate oxide compley to meet the possibility of hot explosion.
5.	with dependence air cycle ordinary is dry to compare,powder form sample will not be flowed,air blows or moves.

though,vacuum dry technology has more numerous advantage,but it is more strict that the workmanship of drying oven compares with the relatively complex requirement for product quality with ordinary oven. a permanent company’s accurate kong wen technical and advanced work manship,the product of guaranteeing us may satisfy your needs.

干燥過程控制

the overall vacuum cycle that vacuunm dry process control may offer program to melt need to set hightest and minimum vacuum degree value respectively according to your requirement,may shorten dry time further.for instance:through program control vacuum cycle,set minimum vacuum degree 50pa and biggest vacuum degree 90pa,circulating frequency is six,if by dry,picture shows process.along with each cycle go on,humidity reduces constantly,dry speed accelerates obviously.biggest circutating frequency mayreach ninety-nine times.

features

1.	cuboid chamber maximizes the effective cubage.microprocessor controller for temperature ensures a precise and reliable control.
2.	dual-layer bullet proof toughened glass door ensures absoluy clear observation on ob-jects in chamber.
3.	shutting extent of oven door is adjustable.closed-cellsilicon gasket ensures a high vacuum degree in oven.
4.	the chamber is made of stainless steel(or wire-drawing sheet),which allows a durable service.
5.	storage,heating,testing and drying are all in an environment without oxygen or filled with inert gases,which ensures no oxidation.
6.	minimum heating time is over 50% less than that of traditional vacuum drying oven.

真空度控制

vacuum drying oven adopts the digital technical control vacuum degree of simulated engineering science,"control by hand"becomes historicallong age.you return think the today lever operating valve of by hand in 21 century may control vacuum degree accuray?
through electromagnetism valve full automatic number the vacuum degree that shows control,foryou,offer the vacuum degree control that has effective accuracy more,hope more offer to give your is more up to date information and more conveniences.pass through panel,vacuum degree from 20par is adjustable to 9999pa,adjustable precision is 1pa.panel shows vacuum degree scope for 1pa,is to 9999pa.vacuum sensor is located in and enters angry mouth and the diffenent location of gas outlet,so,the pressure of having guaranteed to stabilize pressure value,not be bullied the influence that flows the most steady pressure value to the operating panel.

隨著真空干燥技術(shù)不斷進步，在真空條件下控制溫度對樣品進行干燥的方法也越來越受到重視，與常規(guī)干燥法相比所具有的優(yōu)勢如下：

1、	真空環(huán)境大大降低了需要驅(qū)除的液體的沸點，所以真空干燥可以輕松應(yīng)用于熱敏性物質(zhì)
2、	對于不容易干燥的樣品，例如粉末或其它顆粒狀樣品，使用真空干燥法可以有效縮短干燥時間
3、	各種構(gòu)造復(fù)雜的機械部件或其它多孔樣品經(jīng)過清洗后使用真空干燥法，*干燥后不留任何殘余物質(zhì)
4、	使用更安全--在真空或惰性條件下，*消除氧化物遇熱爆炸的可能
5、	與依靠空氣循環(huán)的普通干燥相比，粉末狀樣品不會被流動空氣吹動或移動

真空干燥技術(shù)雖然有以上眾多優(yōu)點，但干燥箱的制造工藝與普通烘箱相比更為復(fù)雜，對產(chǎn)品品質(zhì)的要求也更嚴格。精確的控溫技術(shù)和*的制造工藝，保證我們的產(chǎn)品可以滿足您的需要。

干燥過程控制

整體的真空干燥過程控制可以提供程序化的真空循環(huán)，只需根據(jù)您的要求分別設(shè)定zui高和zui低真空度值，就可以進一步縮短干燥時間，例如：通過程序控制真空循環(huán)，設(shè)定zui小真空度50pa，zui大真空度900pa，循環(huán)次數(shù)6次，干燥過程如圖所示，隨著每一個循環(huán)的進行，濕度不斷降低，干燥速度明顯加快，zui大循環(huán)次數(shù)可達99次。

產(chǎn)品特點

1、	長方體工作室，使有效容積達到zui大，微電腦溫度控制器，控溫精確可靠
2、	鋼化、防彈雙層玻璃門觀察工作室內(nèi)物體，一目了然，能夠向內(nèi)部充入惰性氣體。
3、	箱門閉合松緊能調(diào)節(jié)，整體成型的硅橡膠門封圈，確保箱內(nèi)高真空度。
4、	工作室采用不銹鋼板（或拉絲板）制成，確保產(chǎn)品經(jīng)久耐用。
5、	存儲、加熱、試驗和干燥都是在沒有氧氣或者充滿惰性氣體環(huán)境里進行，所以不會氧化
6、	zui短加熱時間，與傳統(tǒng)真空干燥箱相比加熱時間減少50%以上。

真空度控制

真空干燥箱采用模擬工程學(xué)的數(shù)字技術(shù)控制真空度，“手動控制"早已成為歷史。您還認為在21世紀的今天手動杠桿操作的閥門可以精確控制真空度嗎？通過電磁閥門全自動數(shù)顯控制的真空度，為您提供更加精確有效的真空度控制，更希望提供給您的是更多的信息和更多的方便。通過面板，真空度從20par至9999pa可調(diào)，可調(diào)精度為1pa。面板顯示真空度范圍為1pa至9999pa。真空傳感器位于與進氣口和出氣口不同位置，從而保證了穩(wěn)定的壓力值，不受氣流的影響，把zui穩(wěn)定的壓力值傳送到操作面板上。
