Introduction: The instrument catalyzes many types of organic, pharmaceutical and biochemical reactions such as additions, substitutions, esterifications, hydrolysis, alkanoylations, polymerizations, condensations, cyclizations, and oxidations, as well as solvents for foods, natural products and minerals. Extraction and other physical processes. Applicable to organic synthetic chemistry, pharmaceutical chemistry, food science, quarantine, epidemic prevention, military chemistry, molecular biology, analytical chemistry, inorganic chemistry, petrochemicals, materials science, biomedicine and other related fields. The instrument has important application value in the above-mentioned fields, and induces or accelerates chemical reaction and physical process through the enthalpy effect and entropy effect, and makes the reaction speed hundreds or even thousands of times faster than conventional methods, and simultaneously increases the reaction selectivity and yield. It has made many difficult or slow chemical reactions or physical processes in the past easy to achieve and complete at high speed. TH-1500BY intelligent temperature-controlled dual-frequency ultrasonic extractor is a new ultrasonic extraction device using modern ultrasonic technology combined with intelligent cryogenic temperature system as a physical means. It is mainly composed of high-power ultrasonic generation system, heating system, compressor refrigeration system, temperature measurement and control Temperature system, reflux condensation, stirring system and other components. The instrument uses a single-chip microcomputer control technology and phase-locked loop frequency automatic tracking technology, through a simple keyboard operation to set the data and control the working status. The oscillating frequency of the power amplifier and transducer is phase-sampled so that the phase-locked loop achieves automatic frequency tracking. The power setting and temperature measurement circuit enables the microcontroller to achieve ultrasonic transmission power and over-temperature protection and alarm functions.
