Embodiment 1
[0030] Weigh the broken Ganoderma lucidum spore powder (broken rate of 97%, detect the six common plasticizers, the detected pollution of DEHP is 1.5ppm, DINP is 6.2ppm, DBP is 1.8ppm, BBP is 2.3ppm, DNOP is 4.0ppm, DIDP is 3.2ppm) 6kg, evenly put into the extraction kettle, the extraction pressure is 10MPa, the temperature is 30℃; the pressure of the separation kettle I is 5MPa, the temperature is 30℃; the pressure of the separation kettle II is 5MPa, the temperature is 30℃; CO 2 The flow rate is 180L / h, the extraction time is 3.5 h, and the material volume of the extraction tank is 5.75 kg, the material of the separation tank I is 0.18 kg, and the material of the separation tank II is empty. The materials from the extraction kettle were inspected, and none of the six plasticizer items were detected (the detection limit of DBP is 0.3ppm, and the detection limit of the other five items is 1.0ppm, the same below), and the active ingredient inspection meets the quality standards...
Embodiment 2
[0032] Weigh 4.5kg of broken Ganoderma lucidum spore powder (broken rate reaches 98%, six common plasticizers were tested, and DEHP pollution was found to be 9.3ppm), and put it evenly into the extraction kettle. ℃; the pressure of separation tank I is 5MPa, and the temperature is 25°C; the pressure of separation tank II is 5MPa, and the temperature is 25°C; CO 2 The flow rate is 100L / h, the extraction time is 2 hours, and the material volume of the extraction tank is 4.45kg, the material of the separation tank I is 0.035kg, and the material of the separation tank II is empty. The material from the extraction kettle was inspected, and none of the six plasticizers were detected, and the active ingredient inspection met the quality standards.
Embodiment 3
[0034] Weigh 6.0kg of broken Ganoderma lucidum spore powder (broken rate reaches 96%, detect six common plasticizers, detect DEHP pollution is 2.5ppm, DBP pollution is 1.8ppm) 6.0kg, evenly put into the extraction kettle , at an extraction pressure of 10MPa and a temperature of 20°C; the pressure of the separation tank I is 5.5MPa and the temperature is 20°C; the pressure of the separation tank II is 5.5MPa and the temperature is 20°C; CO 2 The flow rate is 200L / h, the extraction time is 6 h, and the material is discharged to obtain the material amount of the extraction tank: 5.85kg, the material of the separation tank I is 0.095kg, and the separation tank II has no material. The material from the extraction kettle was inspected, and none of the six plasticizers were detected, and the active ingredient inspection met the quality standards.
