Card box radio frequency sterilizing unit

Technical field

The utility model relates to the sterilizing unit of liquid state and semisolid food material, utilizes radio frequency to select the higher modes such as material heating of dielectric constant, and the heating that liquid state and semisolid food material can be rapidly heated reaches the device of bactericidal effect fast.

Background technology

In recent years, very general with use thermal sterilization modes such as beverage or food, it mainly is the treated forms take killing microorganisms as purpose, wherein wet heat sterilization is one of topmost mode, utilize heat converter (such as boiler) to change the heat energy of burning into hot water or steam as heat medium, with heat exchanger the heat energy of hot water or steam is passed to food and beverage again, or steam is directly sprayed in the food to be heated.

Use traditionally the thermal sterilization mode, carry out sterilization mode such as ultrahigh-temperature sterilization UHT (Ultra High Temperature) equipment, but this mode has the problems such as hot conductive impairment, easily causes the incomplete phenomenon of sterilization.

The radio frequency heating sterilization mode can be broken through the problem of traditional hot conductive impairment, its sterilization mode is to utilize to treat the polar molecule that the sterilization object includes itself, under the rf electric field effect, its direction for the treatment of the polar molecule of sterilization object can constantly rearrange rapidly (two like magnetic poles repel each other alternately with rf frequency, the principle that there is a natural attraction between the sexes), cause intermolecular quick rotation friction and give birth to heat, constantly change polar orientation such as hydrone etc., the temperature that causes treating the sterilization object sharply raises and reaches the effect of sterilization.

The utility model utilizes above-mentioned radiofrequency characteristics, Foods or drinks after radio frequency processing, can be avoided traditional hot conductive impairment, the temperature in the Foods or drinks is risen rapidly, can arrive bactericidal effect at short notice, further reach fast, economize can, effective and safe purpose.

Summary of the invention

The purpose of this utility model solves the problem in the background technology, a kind of food and drink sterilizer and system are provided, utilize radio frequency can select the characteristic of the high material heating of dielectric constant, the temperature of food and beverage can be rapidly heated reach bactericidal effect, further reach fast, economize can, effective and safe purpose.
