冷干机

常规的冷干机在使用一年以后，其制冷能力会大大减小。

The refrigerating effect of general refrigeration dryer will be cut down a lot after being used for one year .

最后的分析结果显示，优化后的冷干机在年偿付费用方面可以节约20%左右。

Compared calculation results with experimental datum , which shows that the optimized refrigeration dryer will save cost by 20 percent every year .

因此冷干机具有制冷系统。

Therefore Leng Gan machine having a refrigeration system .

根据年偿付费用最低这一优化准则对冷干机系统进行优化设计。

Cold Mountain 3 . According to the economic optimization rules , a mathematical model was established .

在冷干机中，蒸发器制冷剂的供给及其调节者是通过节流机构来实现的。

In the Leng Gan machine , evaporator refrigerant supply and its regulation is realized through the throttle mechanism .

公司的目标是生产世界一流的发酵罐、冷干机、真空浓缩仪和离心机，领导本行业的发展。

The company is oriented to be a world leader in fermentor , freeze drying , speed vacuum concentrator and centrifuge technology .

在一些的应用领域中，用冷干机是达不到工艺对气源干燥度要求的，如气动仪表、电子工厂等。

In some application areas , with Leng Gan machine is not up to process on the drying air requirements , such as pneumatic instrumentation , electronic factory .

在无法取得直流电源的情况下，利用可控硅元件，也可实现能耗制动。无热再生吸干机前加装冷干机的能耗分析

On the condition without DC power , the SCR could be used to realize dynamic braking . Energy Cost Analysis of Heatless Dryer and Combination of Heatless Dryer and Refrigeration Dryer

在大型冷干机中，也选用半密封往复机或螺杆压缩机，它们的特点是制冷功率大，可进行负荷调节以适应不同需要。

In the large Leng Gan machine , also using semi hermetic reciprocating engine or a compressor , which is characterized by the refrigeration power , can adjust load in order to adapt to different needs .
