| 摘要: |
| 依据国外文献，介绍几种典型的过热蒸汽干燥系统，分析了它们的组成特点，即过热蒸汽干燥系统应有废气再循环利用、物料预热和防止空气渗入等附属部分，采用锅炉不是必备条件。指出对于过热蒸汽干燥系统应从废气利用途径、真空干燥和组合加热等方向进行开发。 |

| Abstract: |
| A new drying technology using direct contact of superheated steam wifh thewet material was developed in recent years. Many typical superheated steam dryingtechnologies such as: fluidized bed, tube-type, self-seal, direct-indirect heating andpneumatic conveying drying system were reviewed. The characteristics of these dryingsystems were analyzed. The reuse of exhaust steam, pre-heating and anti-airinfiltrationshould be included in the system. In some cases,boiler is not necessary. The further development of superheated steam drying will be the reuse of exhaust steam,using of vacuum and combined heating system. |
