随着真空干燥技术不断进步，在真空条件下控制温度对样品进行干燥的方法也越来越受到重视，与常规干燥法相比所具有的优势如下：
| 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 completely. |
| 4. |
use more safety-under vacuum or inertia condition,eliminate oxide completely 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. |
| 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. |

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 absolutely 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. | |
|
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 accurately?
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. |

随着真空干燥技术不断进步，在真空条件下控制温度对样品进行干燥的方法也越来越受到重视，与常规干燥法相比所具有的优势如下：
| 1、 |
真空环境大大降低了需要驱除的液体的沸点，所以真空干燥可以轻松应用于热敏性物质 |
| 2、 |
对于不容易干燥的样品，例如粉末或其它颗粒状样品，使用真空干燥法可以有效缩短干燥时间 |
| 3、 |
各种构造复杂的机械部件或其它多孔样品经过清洗后使用真空干燥法，完全干燥后不留任何残余物质 |
| 4、 |
使用更安全－－在真空或惰性条件下，完全消除氧化物遇热爆炸的可能 |
| 5、 |
与依靠空气循环的普通干燥相比，粉末状样品不会被流动空气吹动或移动 |
| 真空干燥技术虽然有以上众多优点，但干燥箱的制造工艺与普通烘箱相比更为复杂，对产品品质的要求也更严格。精确的控温技术和先进的制造工艺，保证我们的产品可以满足您的需要。 |
| 整体的真空干燥过程控制可以提供程序化的真空循环，只需根据您的要求分别设定最高和最低真空度值，就可以进一步缩短干燥时间，例如：通过程序控制真空循环，设定最小真空度50pa，最大真空度900pa，循环次数6次，干燥过程如图所示，随着每一个循环的进行，湿度不断降低，干燥速度明显加快，最大循环次数可达99次。 |

长方体工作室，使有效容积达到最大，微电脑温度控制器，控温精确可靠 |
| 2、 |
钢化、防弹双层玻璃门观察工作室内物体，一目了然，能够向内部充入惰性气体。 |
| 3、 |
箱门闭合松紧能调节，整体成型的硅橡胶门封圈，确保箱内高真空度。 |
| 4、 |
工作室采用不锈钢板（或拉丝板）制成，确保产品经久耐用。 |
| 5、 |
存储、加热、试验和干燥都是在没有氧气或者充满惰性气体环境里进行，所以不会氧化 |
| 6、 |
最短加热时间，与传统真空干燥箱相比加热时间减少50%以上。 | |
| 真空干燥箱采用模拟工程学的数字技术控制真空度，“手动控制"早已成为历史。您还认为在21世纪的今天手动杠杆操作的阀门可以精确控制真空度吗？通过电磁阀门全自动数显控制的真空度，为您提供更加精确有效的真空度控制，更希望提供给您的是更多的最新信息和更多的方便。通过面板，真空度从20par至9999pa可调，可调精度为1pa。面板显示真空度范围为1pa至9999pa。真空传感器位于与进气口和出气口不同位置，从而保证了稳定的压力值，不受气流的影响，把最稳定的压力值传送到操作面板上。 |
