什么是油料生坯的挤压膨化？挤压膨化的目的？
参考答案：油料料坯的挤压膨化是利用挤压膨化设备将生坯制成膨化颗粒物料的过程。生坯经挤压膨化后可直接进行浸出取油。
目的：油料生坯经挤压膨化后，其容重增大，多孔性增加，油料细胞组织被彻底破坏，酶类被钝化，这使得膨化物料浸出时，溶剂对料层的渗透性和排泄性都大为改善，浸出溶剂比减小，浸出速率提高，混合油浓度增大，湿粕含溶降低，浸出设备和湿粕脱溶设备的产量增加，浸出毛油的品质提高，并能明显降低浸出生产的溶剂损耗以及蒸汽消耗。

| If you are human, you can't help but experience times when everything seems to be going wrong. You must also _1_as if your life is completely out of control at times. It is during those "down times" that words of encouragement from family, friends, co-workers or 2_strangers can boost(增强)your spirits. It is also during those _3_that negative words can be devastating (毁灭性的) and sink you deeper and deeper into depression. For example, consider this story about a group of _4_who were traveling through the woods when _5_of them fell into a deep pit (坑). All of the other frogs gathered around the _6_.When they saw how _7_the pit was, they told the two _8_frogs they would never get out. The two frogs didn't obey what other frogs said and tried to _9_ out of the pit. The other frogs kept telling them not to jump, _10_ it was in vain. Finally, one of the frogs followed what the other frogs were saying and simply _11 . He fell down and _12 . The other frog continued to jump as _13_as he could. Once again the crowd of frogs shouted at him to _14_ the pain. The more they _15_, the harder he jumped and finally he _16_to safety. When he _17 , the other frogs asked him why he continued to jump when they were all _18_ him to simply quit. The frog _19_to them that he was a little bit deaf. He thought they were _20_ him all the time. | ||||
