Abstract

The utility model discloses an alternating electromagnetic sterilizer, comprising a pipe body (1), which is characterized in that an iron core (3) is arranged inside the pipe body (1); a coil is wound on the iron core (3) to form a three-phase winding (2) which is connected with a three-phase power supply; a material pipe (4) is arranged at the centre of the coil. The utility model is a alternating electromagnetic sterilizer for the liquid food sterilization and has the advantages of high safety and good sterilization effect, simple equipment manufacture, low cost, short sterilization time, and good product quality after sterilization.

Description

A kind of alternating electromagnetism sterilizer

(1) technical field:

The utility model relates to sterilization technology field, the alternating electromagnetism sterilizer that a kind of specifically food liquid sterilization is used.

(2) background technology:

As everyone knows, sterilization technology is a key technology in the food industry, and the sterilization technology of food liquid mainly is divided at present: ultra high temperature short time sterilization, high temperature sterilization, cold sterilization and non-heats cold sterilization are several; Because high temperature is bigger to the food quality influence, as make that the color and luster of heat-sensitive materials in the food, local flavor change, fat is built up layering, protein denaturation precipitation etc., thereby the non-heats cold sterilization technology of people's pay attention to day by day, its technology mainly comprises: pulsed discharge sterilization in ultrahigh-pressure sterilization, pulsed magnetic field sterilization, high intensity pulses electric-field sterilizing and the liquid.

Ultrahigh-pressure sterilization be to provide bactericidal effect by prolonging pressing time, but after extending to certain hour pressing time, bacterial number can not descend again, occurs the antagonism that thermal denaturation and pressure sex change weaken mutually simultaneously in ultrahigh-pressure sterilization sometimes; Prolonging pressing time, promote the inactivation of enzyme, but will make the enzymatic activity complete deactivation, is very difficult with pressure method, also can influence the maintenance phase of food simultaneously, and in addition, its sterilizing unit must be made with the overpressure resistant material, thereby equipment operation difficulty, the cost height.

The pulsed magnetic field sterilization, be to utilize the alternating magnetic field kill bacteria, but the used alternating magnetic field intensity of pulsed magnetic field sterilization is generally greater than 6T, current experiments shows, use 12T, 6kHz action of alternating magnetic field milk 10 times, can make year the bacterium that contains in the milk reduce and fall 1%, 40T, the pulsed magnetic field action yeast soln of 60KHz, the solution bacteria containing amount also reduces by 1%, so far do not appear in the newspapers and can kill common bacteria in the food fully with pulsed magnetic field, it is by no means easy to obtain high-intensity magnetic field simultaneously, and high-intensity magnetic field needs high electric current, high electric current requires high to the cooling system of equipment, otherwise equipment moment promptly burns out.

The common intensity of the high pressure main pulse electric field that high intensity pulses electric-field sterilizing, sterilization are used is 15-100kV/cm, and pulse frequency is 1-100KHz, discharge frequency is 1-20Hz, during with the high intensity pulses electric-field sterilizing, because the resistance effect of liquid, temperature of charge rises, and temperature rise can reach 40 degree.Pulsed discharge sterilization in the liquid, the pulsed discharge sterilization mechanism mainly is comprehensive functions such as electrochemical sterilization, the sterilization of shock wave cavitation, heat kill bacterium, electrochemical sterilization and always hit the sterilization of ripple cavitation and play a leading role, the high pressure pulse discharge sterilizing unit is because voltage is higher, can produce electric arc when the discharge sterilization puts, so the property effect to medium is bigger, separate and protein denaturation precipitation as can produce fat to high fat material, the noise of high pressure pulse discharge sterilizing unit is big simultaneously, the higher-pressure region constitutes a threat to the personnel health, since use high-tension circuit, dangerous to operating personnel.

(3) summary of the invention:

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provide a kind of alternating electromagnetism sterilizer, the quality that mainly solves existing sterilizer liquid towards food is influential, and bactericidal effect is poor, equipment making processing difficulties, cost high and to the uneasy congruent problem of operating personnel.

In order to achieve the above object, the utility model is achieved in that a kind of alternating electromagnetism sterilizer, it comprises body 1, its special character is that described body 1 inside establishes iron core 3, winding around forms three phase windings 2 on the iron core 3, three phase windings 2 are connected with three phase mains, establish materail tube 4 at the center of coil.

A kind of alternating electromagnetism sterilizer of the present utility model, its described materail tube 4 is a coiled glass; Described iron core 3 is the silicon steel iron plate.

A kind of alternating electromagnetism sterilizer of the present utility model can adopt one, also can adopt to connect more than one and use.

Compared with the prior art a kind of alternating electromagnetism sterilizer described in the utility model has following good effect: 1, formed magnetic field is alternating magnetic field, can not disturb the operation of peripheral facilities, can operating personnel's health not constituted a threat to, and security is good; 2, owing to adopt silicon steel iron plate winding around to form three phase windings, logically form alternating magnetic field after going up three-phase alternating current, magnetic field intensity can be up to 5000 Gauss spies, and experiment shows that magnetic field emphasizes to reach 700 Gauss spies, the kill ratio that can guarantee is more than 99.8%; 3, adopt the coiled glass of certain diameter to come convey materials by hub of a spool as required, required sterilization material is subjected to the magnetic field even action and can keeps sterilizing time; 4, the material of Cai Yonging easily obtains, and install easy industrialization, and cost is low; 5, sterilizing time is short, and superior product quality after the sterilization prolongs its shelf life.

The A-A cut-away view of Fig. 2---Fig. 1.

(5) specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of alternating electromagnetism sterilizer of the utility model in detail.

Embodiment 1, referring to Fig. 1,2,3, cylinder iron material is made body 1, done unshakable in one's determinationly 3 by the silicon steel iron plate, winding around forms three phase windings, 2, three phase windings 2 and is connected with three phase mains thereon, adopt coiled glass to make materail tube 4, materail tube 4 is installed in the center of coil, and materail tube 4 can adopt different diameters as required, and the two ends with materail tube 4 are connected with batch can respectively at last.

A kind of alternating electromagnetism sterilizer described in the utility model during use, behind the logical upward three-phase alternating current, forms alternating magnetic field, and material evenly passes through from magnetic field through coiled pipe, can reach abundant sterilization in the time of staying in magnetic field by the control material.
