【技术实现步骤摘要】
一种高热均匀性自动化冻干机
本专利技术涉及冻干设备
,特别是涉及一种高热均匀性自动化冻干机。
技术介绍
冻干机是制药行业和食品行业进行药品和食品冷冻干燥的设备,是先将需冷冻干燥的物品(制品)在低温下冻结,然后在真空条件下,通过真空升华和解析吸附的方法,使制品的水分减少到在长时间内无法维持生物学反应和化学反应的水平。托盘是用于转运、盛放待冻干物品,将待冻干物品通过托盘放入到冻干机隔板上进行冷冻的必备工具。因此,托盘的传热效果也是影响待冻干物品冻干效果和冻干效率的主要因素之一。搁板在干燥箱传热中承担大约65%的传热功能,其对物品冻干速率的快慢,冻干均匀性产生重要影响,尤其对于医药行业使用的冻干机,其冻干效果对药品或其中间产物的性能产生重要影响,另外,搁板的第二个重要作用是确保搁板上的所有点及板层(多块搁板组合)所有点温度均匀一致,确保制品在冻干全过程中温差比较小,从而达到降温一致,升温一致,冻干快速、制品品质一致的高要求。现有冻干机的托盘、隔板的传热速率的均匀性相对较差,不能保证不同位置处的待干燥物品同时被冻干,影响冻干效率和冻干质量。
