Description
Technical Field
The invention relates to the technical field of microwave energy, in particular to a container for containing liquid substances and a liquid substance heating device.
Background
Microwave heating is an important field of application of microwave energy, while food heating is an important field of application of microwave processing. For example, in ordinary households, liquid substances such as water, milk, soup and the like are food products that are heated daily. When liquid food contained in a container such as a cup is heated in a microwave generating device, the temperature of the upper part is more than ten degrees centigrade higher than that of the lower part, the heating quality of the liquid food is influenced, and even the liquid food is scalded by the liquid substance on the upper part when the liquid food is drunk. The microwave energy absorption and the liquid substance heat convection cause the temperature of the liquid substance to be high at the upper part and low at the lower part.
When the liquid material contained in the container is heated in a microwave generating device with uniform microwave energy distribution, such as a microwave oven, the microwave energy absorbed by the upper unit mass of the liquid material in the container is larger than that absorbed by the lower unit mass of the liquid material in the same time. The liquid substance is placed in a microwave environment, and can directly absorb microwave energy to heat the liquid substance. When the liquid material contained in the container is heated in the microwave generating device, microwaves heat the liquid material in the container from the side surface and the upper surface of the container simultaneously, the liquid material in the lower part of the container can only receive the microwaves from the side surface, the liquid material in the upper part of the container can also receive the microwaves from the upper surface besides the microwaves from the side surface, the microwave energy absorbed by the unit mass of the liquid material in the upper part of the container is more than that absorbed by the unit mass of the liquid material in the lower part of the container, and the temperature of the liquid material in the upper part of the container is higher than that of the liquid material in the lower.
When the liquid substance contained in the container is heated, thermal convection causes molecules of the liquid substance having a relatively high temperature to gather toward the upper portion of the container. The general liquid substance is expected to be heated to 40-60 ℃ from the storage temperature or room temperature, which is beneficial to human health and obtains better taste. For food using water as solvent, the higher the temperature (> 4 ℃), the lower the density, so that the water molecules with relatively high temperature have the tendency of moving upwards and the water molecules with relatively low temperature have the tendency of moving downwards during heating, which aggravates the temperature difference between the upper and lower parts of the liquid substance in the container.
When the liquid substance in the container is heated, the heat energy is transferred from the upper part of the container with higher temperature to the lower part of the container with lower temperature through heat conduction, which is beneficial to improving the uniformity of the liquid substance in the container.
In summary, when the liquid substance in the container is heated in the microwave generating device with uniform microwave energy distribution, the microwave energy absorption and the heat convection of the liquid substance cause the upper temperature of the liquid substance in the container to be higher than the lower temperature; and the temperature of the liquid substance in the container tends to be consistent by heat conduction, heat radiation and evaporation. Finally, the liquid substance heated by the microwave generating device is caused to have the upper temperature which is more than ten and a few degrees centigrade higher than the lower temperature.
At present, people generally adopt a method that a liquid substance heated by a microwave generating device is placed for a period of time, and then the liquid substance is eaten after the temperature difference between the upper part and the lower part is reduced by utilizing heat conduction; or the liquid substance heated by the microwave generating device is stirred to force the liquid substance to convect, so that the temperature of the liquid substance is uniform. Standing for a period of time, which is contrary to the current faster and faster work and life rhythm; the stirring is complicated, the time is consumed, and the washing of tableware is increased.
Therefore, how to utilize the microwave generating device to directly, rapidly and uniformly heat the liquid substance and improve the quality of life of people becomes a technical problem to be solved urgently.
