本文所谈的工业用冷冻干燥机的研制,其搁版面积为8m~2,搁板温差为-40～+70℃,板间温差为±1.5℃,捕水量为80kg,该机具有板距可任意调节,并可停留在任何位置,便于装卸制品;干燥箱可以调压;可利用压缩机排气作为升华加热热源;箱内装有清洗装置等功能。在国内首次在冻干机上采用微机控制,可跟踪冻干曲线提前计算加热量,同时还有一套独立的手动操作系统,确保运行的可靠性。
This article talked about the development of industrial freeze-drying machine, the shelf area of 8m ~ 2 shelf temperature difference of -40 ~ +70 ℃, the temperature difference between the plates is ± 1.5 ℃, the water capture capacity of 80kg, the machine has a board distance Can be adjusted, and can stay in any position, easy to load and unload products; Oven can be pressure; compressor exhaust can be used as sublimation heat source; box equipped with cleaning devices and other functions. In the country for the first time in the freeze-drying machine using computer-controlled, freeze-drying curve can be tracked in advance to calculate the amount of heating, along with a set of independent manual operating system to ensure the reliability of operation.
