| 中文摘要: |
| 在玉米胚芽预榨饼浸出制油过程中，湿粕脱溶是一个很重要的工序。基于玉米胚芽预榨饼的特点，对其浸出过程中湿粕脱溶工艺和设备进行了改进，并应用于生产实践。采用浸出器强制沥干和新型的高料层蒸脱机的技术方案，在强制沥干真空度1 500 Pa、蒸脱机脱溶层净高3 600 mm、脱溶时间35~40 min条件下，粕残溶达到650 mg/kg及以下，闪爆实验合格。通过采用新工艺和新技术，能在保证玉米胚芽粕产品品质的同时达到节能降耗的目的。 |
| 英文摘要: |
| In the process of oil extraction from corn germ pre-pressed cake, wet meal desolventizing is a very important process. Based on the characteristics of corn germ pre-pressed cake, the process and equipment of wet meal desolventizing were improved, and it was applied in production practice. Using forced drainage in extractor a new type of high material layer DTDC, under the conditions of forced drainage vacuum 1 500 Pa, net height of DTDC′s desolventizing layer 3 600 mm, and desolventizing time 35-40 min, the residual solvent in meal was 650 mg/kg and below, and the flash explosion test was qualified. Through the adoption of new processe and new technology, the quality of the meal can be guaranteed at the same time to achieve the purpose of energy saving and consumption reduction. |
