Note: the two sides of the semiconductor refrigerating plate are respectively the cold end face and the hot end face, which can respectively absorb heat and release heat to realize the purpose of refrigeration.

Use scenario examples:

1. the food processing apparatus of fig. 3 and 4 may be used to prepare cold drink a directly.

The preparation method comprises the following steps: taking a proper amount of tea (coffee, milk tea and the like), putting the tea into the accommodating cavity 11, then adding a proper proportion of water 7, turning on a power switch, starting the ultrasonic generator 21 and starting the refrigerating device 33; after tea leaves (coffee, milk tea and the like) are extracted to a certain degree, the ultrasonic device is closed to finish the preparation; subsequently, the refrigeration device 33 is turned off and the power is turned off according to the refrigeration requirement.

3. Selection of refrigeration temperature and time

Firstly, rapidly refrigerating, and cooling for 3-10min to 0-10 ℃; then refrigerating at constant temperature or keeping fresh for 10 mm-10 h.

The principle is as follows: the ultrasonic wave is a mechanical wave with a frequency higher than 20kHz, and various effects (cavitation effect, mechanical effect, thermal effect, free radical effect and the like) caused by the ultrasonic wave can peel off and destroy the histiocyte of the food material 8, and release nutrient substances and flavor small molecules in the food material 8.

Meanwhile, the ultrasonic wave plays a role in increasing stirring and diffusion, is beneficial to quickly leaching the contents of the food materials 8 such as tea or coffee and the like, and shortens the making time.

The ultrasonic action is beneficial to the extraction of pigskin protein, the concentration of the soup is increased, and the cooking time is shortened. The heating and cooling device is integrated, and the soup does not need to be poured into another appliance from the heating pot to be refrigerated in the refrigerator.
