摘　　要：为了研究和优化血浆速冻机系统,保证血浆的速冻质量,本文分析了平板式血浆速冻机的特点,设计并搭建了内容积约能容纳36袋200ml血浆的平板式速冻机实验装置,使用R507作为双级压缩制冷循环工质,实现了血浆速冻机达到-60℃的低温条件,并且实验表明了所设计的平板式血浆速冻机在不同的环境温度下都能将血浆的中心温度在40min内由常温速冻到-30℃以下,但是血浆冻结速度还不够均匀,同一批血浆中心温度达到-30℃的时间最大可相差10min。In order to study and optimize the plasma quick freezing machine system and guarantee the quality of frozen plasma, this paper analyzes the characteristics of the flat plate plasma freezer and design and set up an experi- mental device of a plate freezer which can hold 36 bags of 200ml plasma. The cryogen of two stage compression refrigeration cycle system is R507. The plasma freezer can reach the low temperature of - 60. The result of experiment shows that the central temperature of the plasma can reach - 30 degrees Celsius from normal atmospheric temperature in 40min. But the plasma freeze is not uniform enough. The same batch of plasma center temperature reached - 30 degrees Celsius, the maximum can be a difference of 10min.
