The invention belongs to the technical field of separation devices, particularly relates to an ultrasonic extraction device and method for
areca alkaloid, and aims to solve the problems that the
system temperature is increased due to the
cavitation effect and the mechanical effect of an existing ultrasonic extraction device while the extraction rate is increased, the extraction time is prolonged, the efficiency is reduced if low-power or intermittent operation is adopted for
temperature control, and in addition, the extraction efficiency is reduced. Conventional single-frequency single-point
ultrasound easily generates standing
waves and dead angles, resulting in non-uniform mixing of feed liquid, local overheating or insufficient extraction, the invention provides the following scheme: the device comprises a tool base, and an
ultrasonic generator is arranged above the tool base. According to the ultrasonic extraction device and method for the
areca alkaloid, the extraction efficiency is improved through low-frequency wall breaking and high-frequency
mass transfer, meanwhile, the uniformity and
repeatability are ensured through planetary stirring, and the effects that accurate
temperature control is achieved, heat loss is avoided, and the production efficiency and safety are improved through a full-automatic closed process are achieved.
