Introduction: XH-2008DE intelligent temperature-controlled dual-frequency ultrasonic extractor is a new type of ultrasonic extraction device using modern ultrasonic technology combined with intelligent cryogenic temperature system as physical means. It mainly consists 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. According to the viscosity of the reactants and the temperature, automatic tracking can automatically achieve the best ultrasonic effect. The instrument adopts high-power ultrasonic transducers of 25KHz and 40KHz frequency, immersing the ultrasonic probe directly in the container for holding the material, measuring the temperature and controlling the temperature of the material, and placing the cold well of the material container according to the needs of the user. Heating and cooling are used to cool down the material in a low temperature environment under the direct action of ultrasonic rapid and adequate extraction. Technical Parameters: 1. Ultrasonic power: 0 ~ 1500W continuously adjustable; 2. Ultrasonic frequency: 25±1KHz; 40±1KHz, with frequency automatic tracking function; 3 cold well temperature measurement and temperature control range: -20 ~ 99 °C; temperature control accuracy: ± 1 °C; 4.
