Vacuum freeze-drying is a technology used for drying, color protection, fresh keeping, or nutrition preservation of food, biologics, biomaterials, or micro/nano materials. Its principle is to use sublimation principle under the vacuum state, and to obtain dried products, whereby frozen water in the material sublime or shift directly from the frozen state to a gas state, and watery element is removed without melt.

冷冻真空乾燥技术是一项适用於食品、生物制品、生医材料、微奈米材料的乾燥、护色、保鲜、保存、保营养成分的技术，其原理是在真空状态下，利用升华原理，使预先冻结的物料中的水分不经过冰的融化直接以冰态升华为水蒸气而除去，从而获得乾燥制品。

We want to cooperate with your company for your company provide matching vacuum circuit breakers and vacuum contactors.

我们想与贵公司开展合作，为贵公司提供配套的真空断路器和真空接触器。

These people have no association with us whatsoever. Most of them don't even have a factory, and the so-called "Italian vacuum driers" they have been trying to copy are nothing like ours. None of them meets our standards and none has the all important controller technology which is essential to the success of our vacuum drying.

这些人和我们一点关连都没有，而他们所称制造的&意大利真空乾燥窑&更是无法与我们的相比---因为很多这些人工厂里工人都没有的，不只达不到我们的质量标准，更重要的是他们的产品都缺乏了我们的电脑控制系统，而这个电脑控制系统及它配置的乾燥程序才是我们真空乾燥科技的精髓！
