Problems solved by technology

[0002] At present, most of the functional heads of the ultrasonic transducers used for chemical reaction and extraction are placed outside the wall of the reaction vessel. As a result, the transducer acts indirectly on the solution in the vessel through the metal plate, causing the solution to cavitate The disadvantage is that due to the mutual interference between the ultrasonic transducers on the metal plate, the ultrasonic function effect is greatly weakened

Embodiment 1

[0029] Put water and edible strawberry flavor according to (water: essence = 100: 10 (kg / g)) through the feed port, and turn on the switch of the ultrasonic generator. The selected ultrasonic frequency is 15kHz, one ultrasonic generator forming the ultrasonic processor of the present invention, each power of 6 ultrasonic transducers is 5-500W, and each of the six ultrasonic transducers is distributed on each of the six walls of the cube container. , and no symmetry; each transducer generates a sine wave, and the material stays in the processor for 10 seconds at a temperature of 40°C. The material is directly connected to the yogurt or beverage production line at the discharge port. After testing, the emulsification is thorough. Preservation for 35 days did not produce separation phenomenon.

Embodiment 2

[0031] Put the pulverized (20-mesh sieve) tea leaves and water into the container according to tea: water = 1:20 (kg / kg), turn on the switch of the ultrasonic generator, select the ultrasonic frequency 25kHz, the total power is 15 ~ 2500W, 5 ultrasonic waves The power of each transducer is 5-500W, and one is distributed on each of the five walls of the cube container, and there is no symmetry; each transducer generates a sine wave, and the temperature is 85°C. The material stays in the processor for 8 seconds. A separator is connected to the discharge port to concentrate the solution or directly use it in beverage production. After testing, the light absorption value of the solution at the discharge port reaches the maximum, and the light transmittance is the minimum.

Embodiment 3

[0033] Put zein and ethanol 1:10 (kg / kg) into the processor, select 2 ultrasonic transducers with frequencies of 15kHz, 25kHz, and 48kHz each, and each of the 6 ultrasonic transducers has a power of 5-150W. Power 15-900W; distributed on each of the six walls of the cube container, there is no symmetry; each transducer generates a sine wave, the temperature is 50 ° C, the time is 15 minutes, and the discharge port is connected to the separator for separation After testing, zeaxanthin and gliadin were completely extracted.

[0034] It can be seen from the above examples that the ultrasonic functional device of the present invention has been practically applied by the School of Food and Bioengineering of South China University of Technology, and compared with the prior art equipment, it has obvious advantages after evaluating the practical effect, and its characteristics are as follows:

[0035] 1. Increase production. The traditional method is a batch reaction, but now it is a ...

Abstract

An ultrasonic treating equipment is composed of the electrically connected ultrasonic generator and ultrasonic transducers in the form of strip or rod, and a container. Said ultrasonic transducers are fixed to the inner surface of container for generating a continuous ultrasonic field acting on the solution in said container. Its advantages are low loss of ultrasonic energy and low noise.

Description

technical field [0001] The invention relates to an ultrasonic processor, in particular to a continuous multifunctional ultrasonic processor. Background technique [0002] At present, most of the functional heads of the ultrasonic transducers used for chemical reaction and extraction are placed outside the wall of the reaction vessel. As a result, the transducer acts indirectly on the solution in the vessel through the metal plate, causing the solution to cavitate The disadvantage is that due to the mutual interference between the ultrasonic transducers on the metal plate, the ultrasonic function effect is greatly weakened. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of ultrasonic transducer functional head is placed in the container, directly act on the solution in the container with the strong continuous ultrasonic functional field through the ultrasonic transducer, make Continuo...
