Ultrasonic extraction equipment in the use of the process of temperature and time control is more important, will directly affect the final extraction of the purity and quality of the object, some ultrasonic extraction equipment with a temperature control function, but some do not bring, for any kind of extraction equipment we need to carry out the temperature and extraction time control properly, otherwise there will be a great impact.
The temperature is generally between 30 to 50 ℃ for ultrasonic enhanced extraction, will not destroy some of the herbs with heat instability, easy hydrolysis or oxidation of the active ingredients. The ultrasonic time is generally controlled at 30 minutes is appropriate.
