XY-SGY系列凍干機 冷阱與(yu)箱體都是分隔的，通過一個氣流通道連接。 采用整合(he)的水平冷阱。更大規格(ge)的設(she)備(bei)冷阱安(an)裝在箱體后面。
本(ben)項目冷(leng)阱排布形式請參閱附件(jian)的(de)圖。
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.
設備容器材料為AISI 316L 不銹鋼。冷阱容器內部機械拋光至<0.75μmRa 。
接(jie)管(guan)有一定的傾斜度，以確(que)保(bao)液(ye)體的排(pai)出(chu)，長徑(jing)比小(xiao)于6:1。
冷(leng)阱保溫采用聚(ju)(ju)合發(fa)泡材(cai)料或聚(ju)(ju)合發(fa)泡材(cai)料與玻(bo)璃纖維的混合材(cai)料，外覆金屬板裝飾(shi)。
冷阱側面(mian)安裝一個(ge)帶照明的(de)直徑150mm (6") 觀察鏡。
冷阱都裝有一(yi)個位于低點的排放口。所(suo)有的排放管都焊(han)接保護(hu)網，以防止冰塊堵塞。
在冷阱的頂部安裝(zhuang)有一(yi)個(ge)噴(pen)嘴(zui)，用于噴(pen)灑熱水或(huo)蒸汽，在工(gong)藝處(chu)理的Z后階(jie)段進(jin)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.

The minimum condenser temperature is -75°C and cooldown from +20°C to -40°C is achieved within 30 minutes, under no load conditions.
每組(zu)冷(leng)凝盤管(guan)(guan)都(dou)通過(guo)RTD 溫(wen)度(du)探頭監控，溫(wen)度(du)探頭安裝在(zai)冷(leng)凝管(guan)(guan)的中間部位，可以在(zai)不進入冷(leng)阱的情況下(xia)更換(huan)溫(wen)度(du)探頭。
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
