Embodiment 3
[0089] A method for evaluating aroma loss in airflow drying equipment process, including:
[0090] 1) Install a galvanized steel pipe with an inner diameter of 20mm on the moisture exhaust steam pipeline about 3 meters behind the moisture exhaust damper of the airflow drying equipment (HXD of Dicksin-Legg, UK, the same below) to control the steam flow; Connect with a glass tube with a suitable diameter and length according to local conditions and a suitable interface, and introduce steam into the steam introduction pipe 1 (spherical interface) of the simultaneous trapping and extracting instrument (the simultaneous trapping and extracting instrument of Example 1 is used in this embodiment);
[0091] 2) At the same time, a glass container with a certain volume is connected to the aqueous phase outlet pipe 9 of the trapping extractor;
[0092] 3) Connect the flat-bottomed flask to the organic phase outlet tube 8 of the simultaneous trapping and extraction instrument, add 60mL of...
