Embodiment 1
[0034] Take raw materials to be frozen: 90 parts of distilled water, 10 parts of sucrose, dissolve them completely to obtain a sucrose solution, and test the initial freezing point of the sucrose solution.
[0035] Circulate the solution for 5 minutes at 20°C with an ultra-micron bubble generator. After the cycle is complete, use a vortex flowmeter to check whether the gas content of the sample is between 82-90%, and the particle size of the bubbles is 300-800nm; if it has not reached range, recirculate for 1 to 2 minutes until the gas content reaches the range. figure 1 It is the distribution of the bubbles in the sucrose solution with a gas content rate of 85% after circulating through the micro bubble generator. Then, the bubble-laden sample was passed through an ultrasonic processor with a condensing circulation system. The temperature of the condensed circulating liquid is maintained at -20°C by the refrigeration system, and a T-type thermocouple is placed in the ultraso...
Embodiment 2
[0038] Raw materials to be frozen: 60 parts of distilled water, 35 parts of sucrose, and 5 parts of maltodextrin. It was completely dissolved to obtain a solution, and the initial freezing point of the solution was tested.
[0039] Use an ultra-micron bubble generator to circulate the solution for 5 minutes at room temperature. After the cycle is completed, use a vortex flowmeter to detect whether the gas content of the sample is between 82-90%, and the particle size of the bubbles is 300-800nm; if it has not reached the range , and recirculate for 1-2 minutes until the gas content reaches the range. Pass the bubble-laden sample through an ultrasonic processor with a condensing circulation system. The condensed circulating fluid is maintained at -22°C by a refrigeration system. Place 3 T-type thermocouples in different positions of the instrument. When the T-type thermocouple detects that the average temperature is -3°C, start 0.4W / cm 2 Ultrasound is carried out in a cycle...
Embodiment 3
[0041]Raw materials to be frozen: 2L of apple juice (11-13°Brix), test the initial freezing point of the apple juice. Circulate it with an ultra-micron generator at room temperature for 8 minutes. After the cycle is completed, use a vortex flowmeter to check whether the gas content of the sample is between 82 and 90%. If it has not reached the range, recirculate for 1 to 2 minutes until the gas content rate reaches the range. Pass the bubble-laden sample through an ultrasonic processor with a condensing circulation system. The condensed circulating fluid is maintained at -20°C by a refrigeration system. Place 3 T-type thermocouples in different positions of the instrument. When the T-type thermocouple detects that the average temperature is -2°C, start 0.5W / cm 2 Ultrasound is carried out in a cycle of working for 2s and pausing for 8s. When the average temperature drops to -2°C again, stop at 0.5W / cm 2 Ultrasonic and start 0.9W / cm 2 Ultrasound, with 2s work, 8s pause cyc...
