Description
Technical Field
The invention discloses a high-quality quick-freezing device and a quick-freezing method, relates to the field of quick-freezing preservation, and particularly relates to a quick-freezing device which is matched with frozen food by auxiliary means such as an electric field, a magnetic field, ultrasonic waves and the like.
Background
Quick-frozen food is more and more widely taken into the lives of people, but in the traditional quick-freezing technology, due to factors such as cell damage caused by ice crystal growth and the like, the quality guarantee period of the food after quick freezing is prolonged, but the quality of the food is reduced to different degrees, and in order to improve the quality of the food, people find that ultrasonic waves, electric fields and magnetic fields are respectively applied in the freezing process to have certain influence on the quality of the food.
The ultrasonic wave can increase the supercooling degree of food and generate cavitation effect in the freezing process, promote the formation of ice nuclei and shatter large ice crystals at the same time, so that the size of the ice crystals is reduced and the number of the ice crystals is increased, and the ultrasonic wave is applied in the freezing process to enhance heat transfer and mass transfer and strengthen heat exchange; the ice nucleus can be triggered by applying a static electric field in the process of freezing food, ice crystals easily grow along the direction of the electric field, and the phase change time is increased. If a dynamic electric field is applied in the process of freezing food, the supercooling degree can be increased or reduced according to the difference of frequency, and in addition, the dynamic electric field can prevent water molecules from gathering, inhibit the formation of ice nuclei and not influence the growth of ice crystals; the static magnetic field is applied to prevent water molecules from gathering, the phase change time is reduced, and supercooling or reduction or increase is realized according to different magnetic field strengths; the application of a dynamic magnetic field can prevent water molecules from aggregating, increase the nucleation temperature, reduce the size of ice crystals and trigger the formation of ice nuclei.
The freezing process of food is very complex in practice from a microscopic perspective, the atomic speed of the original thermal motion is reduced along with the reduction of the external temperature, when the kinetic energy of atoms is extracted by continuously reducing the temperature, the atoms cannot be static and can precess (move according to the age), and the effects of an electric field and a magnetic field on substances can be really explained and clarified only by entering the microscopic quantum field, so that the research on the freezing of food under the conditions of the magnetic field and the electric field is mostly stopped at a research stage.
Most of quick-frozen foods contain much water (the water content of meat is generally about 70%, the water content of aquatic products is generally more than 80%), and water molecules are polar molecules and can be controlled by electric field force and magnetic field force.
Under a certain magnetic field condition, the water molecules are exposed to the magnetic field, so that the polarity of the water molecules can be increased, and the water molecules with the increased polarity are more easily controlled by the electric field and the magnetic field.
The traditional freezing mode begins to freeze from the outer surface, slowly extracts heat layer by layer, and is greatly influenced by the thermal resistance of a freezing layer.

At the moment, the action of the oscillating magnetic field and the oscillating electric field starts to be highlighted, and because the oscillating electric field and the oscillating magnetic field work in a coordinated mode, when the electric field is a positive value and the magnetic field is a negative value, the polar molecules acquire energy kinetic energy and increase the motion radius of the polar molecules, the motion track of the polar molecules can be considered to be more linear, and the polar molecules can easily pass through a crystal nucleus crystallization area. The ice crystal can not grow, be 0 value when the electric field, magnetic field is when the positive value, take away the heat through external refrigerating system, the kinetic energy of molecule reduces and polar molecule motion radius reduces, also be exactly that polar molecule does the circular motion of small radius, this polar molecule is difficult for passing the crystal nucleus crystallization region, make the hydrone arrange according to the hydrogen bond rapidly around the crystal nucleus, the ice crystal is grown, because in the continuous oscillation of electromagnetic field, the ultrasonic cavitation effect and static magnetic field can make the production crystal nucleus that the flesh of fish does not stop, cause the hydrone continuous growth on the new crystal nucleus of producing, break, nucleation, regrowth is broken again, in order to realize the purpose that the ice crystal size reduces.
The time of the nucleation and nucleation growth stages in the food is very short, but the freezing time of the whole food is relatively long because ice crystals with small size and large quantity are needed to be generated in the food to achieve the purpose of inhibiting the bacterial reproduction at low temperature of the whole food. Is favorable for improving the speed and preserving the quality of the frozen fish meat.
