Embodiment 1
[0025] Material source: The biotransformation reaction liquid of androstenedione in the upper section adopts a two-liquid-solid-solid four-phase process, and the obtained biotransformation reaction liquid is a liquid-liquid-solid-solid four-phase system, and the liquid phases are water phase and The oil phase (food grade vegetable oil), the solid phase are the cells and the medium containing the product respectively. The vegetable oil can be corn oil, rapeseed oil, sunflower oil, soybean oil, peanut oil, salad oil, edible blending oil, etc.
[0026] The separation process steps are as follows
[0027] Step 1: Place the liquid-liquid-solid-solid four-phase system in the washing tank and settle naturally. Temperature, 10°C, settling time: about 10 hours.
[0028] Step 2: Open the discharge valve at the bottom of the washing tank, discard the heavy water phase to the three waste collection pool, the liquid-solid-solid three-phase feed liquid left in the washing tank; the liquid...
