Description

technical field [0001] The invention relates to the technical field of microwave heating, in particular to a food heating production line with microwave suppression function. Background technique [0002] Microwave heating is a kind of radiation heating. Generally, the frequency of microwave heating is 2450GHz, which makes the water molecules of the heated material oscillate, and the molecules rub against each other to generate heat, so that the inside and outside are heated at the same time, without the need to transfer heat by convection or conduction. Therefore, the heating speed is fast, the thermal efficiency is high, the processing time is short, and the temperature inside and outside the material is uniform, so energy is saved, the drying efficiency is high, and the drying quality is good, which is deeply loved by people. [0003] With the continuous development of industrialization, food industry microwave equipment, as a new type of energy-saving and consumption-red...

AI Technical Summary

Problems solved by technology

The disadvantages of these methods are: since the shielded energy leakage suppressor cannot realize continuous production of microwave heating equipment, although its suppression effect is good, it is not ideal as a tunnel type industrial microwave heating equipment, and the reactive energy leakage suppressor can be used. To suppress several main transmission modes of microwave, if all modes are to be suppressed, the length of the suppressor is required to be long enough, and the equipment occupies a large space; and the resistive energy leakage suppressor needs such as ferrite, More than a dozen dissipative attenuation materials such as graphite, activated carbon, and water can absorb microwaves in various frequency modes. The suppressor will absorb microwave energy, which is not conducive to high efficiency and energy saving of equipment. Because water is economical, clean, and Recyclable, easy to use and other characteristics, so water as a microwave energy leakage suppression material is suitable for the actual production requirements of various enterprises, especially food enterprises

However, if water is required to suppress all transmission modes, a large amount of water is required as a load, which brings difficulties to the manufacture and processing of water-loaded equipment. Therefore, the current separate microwave suppression methods in the food industry microwave equipment all have the following Several problems: poor leak-proof ability; bulky; difficult to process
