The disclosed Improvement type up flow type closed circulation extraction equipment of this creation, to using extract liquor, to extract tea raw material, it includes at least one filling object fixed frames in an extraction kettle, a storage barrel, a side Pu, first feed-line, second feed-line, a third feed-line and the extraction kettle. Wherein Pu system, side is to push the extract liquor. Extraction kettle is then, wherein the side Pu is connected to the bottom of the extraction kettle via one first feed-line, the extract liquor to be imported in the extraction kettle to the built-in tea raw material； One second feed-line is wherein connected at the top of the extraction kettle, the extraction kettle is discharged in the extract liquor. The top of storage barrel is connected to second feed-line, to store the extract liquor for coming from the extraction kettle. The bottom of storage barrel is connected to a third feed-line, storage barrel is discharged in extract liquor and is directed to the side Pu. The another wherein described charges body fixed frame can be fixedly connected at least one filling object, to adjust the volume in the extraction kettle.本創作所揭露之改良式上流式封閉循環萃取設備，用以利用萃取液以萃取茶葉原料，其包含一個萃取釜、一個儲存桶、一個幫浦、一個第一輸送管線、一個第二輸送管線、一個第三輸送管線、以及所述萃取釜內至少一充填物體固定架。其中幫浦係用以推動所述萃取液。萃取釜則係用以內置所述茶葉原料，其中所述幫浦經由一第一輸送管線連接至所述萃取釜之底部，以將所述萃取液導入所述萃取釜內；其中所述萃取釜的頂部連接至一第二輸送管線，用以將所述萃取液排出所述萃取釜。儲存桶之頂部連接至所述第二輸送管線，用以儲存來自所述萃取釜之所述萃取液。儲存桶之底部連接至一第三輸送管線，用以將萃取液排出儲存桶並導引至所述幫浦。另其中所述充填物體固定架可固定連接至少一充填物體，用以調整所述萃取釜內之容積。
