XY-SGY系列冻干机 冷阱与箱体都是分隔的，通过一个气流通道连接。  采用整合的水平冷阱。更大规格的设备冷阱安装在箱体后面。

本项目冷阱排布形式请参阅附件的图。

The cold trap of XY-SGY series freeze-drying machine is separated from the box and is connected by an air flow channel. Equipment below uses an integrated horizontal cold trap. The larger equipment cold trap is installed behind the box.

 设备容器材料为AISI 316L 不锈钢。冷阱容器内部机械抛光至<0.75μmRa 。

接管有一定的倾斜度，以确保液体的排出，长径比小于6:1。

冷阱保温采用聚合发泡材料或聚合发泡材料与玻璃纤维的混合材料，外覆金属板装饰。

冷阱侧面安装一个带照明的直径150mm (6") 观察镜。

冷阱都装有一个位于低点的排放口。所有的排放管都焊接保护网，以防止冰块堵塞。

在冷阱的顶部安装有一个喷嘴，用于喷洒热水或蒸汽，在工艺处理的Z后阶段进行化霜。

The vessel is fabricated from AISI 316L stainless steel. The internal surfaces of the condenser vessel are mechanically polished to <0.75mRa. 

Nozzles are pitched to ensure drainage of liquids and have an aspect ratio less than 6:1 to ensure sterilisation should this option be included.

The condenser vessel is externally insulated with a polymer foam insulation and clad with sheet metal to protect the insulation material.

An illuminated 150mm (6") sight glass is fitted to the side of the condenser body. 

A low point drain is fitted in the condenser. The drain is fitted with a welded mesh cover to prevent ice blocking the drain. 

A spray ball(s) is fitted in the roof of the condenser to spray hot water for removal of ice at the end of the process.

The condensing surface within the condenser body comprises a number of polished 316L stainless steel tubes welded to form a series of coils, configured to allow oil drainage. The coils have an external finish of <0.75mRa. A series of coils are manifolded in parallel to form a coil circuit. Each circuit is cooled by the direct expansion of refrigerant gas supplied by a dedicated compressor. The number of circuits and compressors varies between Lyomax models, however the condensing surface area of all models is at least equivalent to the shelf surface area to provide optimum condenser performance during peak sublimation.

在冷阱内的冷凝面包括几组抛光的不锈钢管焊接成连续的螺旋状

盘管。冷凝管的外表面抛光<0.75μmRa 。每组冷凝管均通过压缩

机直接供应的制冷气体直接膨胀制冷。冷凝管和压缩机的数量取

决于冷凝器的大小。冷凝面积与板层面积的比例基本上1:1，这样

可以在升华的峰值时得到Z佳的冷阱捕冰效果。

冷阱Z低温度可达到 -75°C，空载降温速度是在30 分钟内从 +20°C 到 -40°C。

The minimum condenser temperature is -75°C and cooldown from +20°C to -40°C is achieved within 30 minutes, under no load conditions.

每组冷凝盘管都通过RTD 温度探头监控，温度探头安装在冷凝管的中间部位，可以在不进入冷阱的情况下更换温度探头。

Each condenser cooling circuit is monitored by an RTD temperature probe which is mounted in a thermal well located approximately mid-length along one coil of each circuit to enable its removal for calibration and service without the need to open the condenser
