Description
Technical field
The utility model relates to agricultural product intensive processing field, relates in particular to a kind of pulsed multi-frequency ultrasonic bioprocess apparatus of frequency sweep mode and in the application in agricultural product intensive processing field.
Background technology
Usually be frequency that the ripple of 20kHz～10MHz is called ultrasonic wave, it is a kind of elastic mechanical ripple of in medium, propagating, ultrasonic technology is as a kind of physical means and instrument, can in the medium that chemical reaction is used always, produce a series of extreme conditions that approach, as produce local and high temperature moment, high pressure etc., this energy not only can excite or promote chemical reaction, accelerate chemical reaction velocity, even can also change the direction of some chemical reaction.Falling field such as poly-at extraction separation, the preparation of biologically active peptide, the polysaccharide of active ingredient of natural product has in recent years obtained using comparatively widely.
A large amount of studies show that, ultrasonic wave promotes that chemical reaction is relevant with acoustic cavitation effectiveness, mechanical effect and fuel factor.Acoustic cavitation effectiveness is meant when the ultrasonic wave of certain intensity is propagated in liquid medium, be present in the micro-bubble in the liquid, under the effect of ultrasonic field, be activated, show as a series of dynamic processes such as formation, vibration, growth, contraction and even collapse of complex, and the physics and the chemical effect that cause.
Hu Aijun etc. (" the phonochemistry yield progress of multiple frequency ultrasonic irradiation ", " acoustic technique " 22 volume 1 phases (2003), 62 pages) be described in the frequency range such between 20kHz～60kHz, supersonic frequency increases, the sonochemistry reaction power strengthens, and the sonochemistry yield increases thereupon; The phonochemistry yield that the composite ultraphonic radiation of double frequency or multifrequency produces can significantly promote chemical reaction, accelerate chemical reaction velocity much larger than the phonochemistry yield sum of two single-frequency difference radiation.Research is also found to select for use batch (-type) to launch hyperacoustic mode, can strengthen ultrasonic treatment effect.In running order when ultrasonic transmitter, biological cell is subjected to strong ultrasonic vibration; When remaining static, system homogenizing, cell relax.The step stressed destruction of strengthening pair cell, help the carrying out of mass transport process, also help lend some impetus to chemical reaction, accelerate chemical reaction velocity.
Chinese invention patent " triple-frequency ultrasonic extraction device and using method thereof " (ZL200610124003.1) adopts that three kinds of frequencies are ultrasonic works simultaneously, confirms that really it is to the extraction efficiency of the Chinese herbal medicine effective ingredients ultrasonic extraction equipment apparently higher than single-frequency.This patent has been used the probe type ultrasonic wave producer, and the weak point of this generator is needing in the laboratory only to be suitable for ultrasound intensity extraction material big, that treating capacity is few; Detecting head surface can be subjected to cavitation corrosion, can reduce hyperacoustic luminous efficiency, and the cavitation corrosion thing can be fallen in the volume, can pollute extract solution; There is ultrasonic field problem pockety in liquid.
In order to overcome single-frequency and the multiple deficiency that exists frequently, Zhang Shuce has designed a kind of sweep-frequency B ultrasonic generator (swept frequency range 28～73kHz), be used for research (Shandong Textile science and technology to the ramee degumming effect, 2006 the 3rd phases), here said " frequency sweep " refers to operate carrying out a frequency sweep in a certain bigger frequency band at the appointed time, promptly sends the continuous ultrasound of different frequency at the appointed time." sweep-frequency B " ultrasonic wave of this article definition is because the frequency range wide coverage, purpose is to make most cavitation nucleus reach best cavitation effect in the short period of time, thereby can play the removal effect to the glue impurity in the big small gap of difference simultaneously, shorten the ultrasonic wave usually time greatly, improved degumming effect.
