摘要:

应用高温干燥与常温干燥有机结合的工艺技术(简称蒸汽综合干燥法),对意杨25mm厚板材进行处理,在预热阶段进行充分的汽蒸处理,而后进入常压过热蒸汽干燥工艺阶段,当含水率降到25%时,转入常温干燥工艺阶段,直到干燥阶段结束。这样既缩短了干燥周期又提高了干燥质量,同时也提高了干燥窑的生产效率。

Abstract:

In this paper, the 25 mm thickness Italian poplar thin board had been dried in the condition of comprehensive vapor drying technology with combination of high temperature drying and normal temperature drying technology in this experiment for more than one year. During preheated stage, the board was completely steamed, then changed to high temperature drying stage with over-heat steam in conventional pressure, the drying was continued till moisture content reached 25%, and then changed to normal temperature drying technology until the end of drying. The test results showed that the comprehensive vapor drying technology would not only shorten drying time, but also improve drying quality, as well as increase efficiency of produce.

Key words: Italian poplar thin board, high temperature drying, normal temperature drying, drying quality
