Abstract
A food sterilization dedicated box type microwave equipment includes a box body (1), a processing box door (2), supporting legs (3), a motor (4), a time relay or a switch (5), an indicator light (6), a rotary plate (7) and a microwave feed port (8), wherein, the microwave feeding ports are simultaneously arranged above and below the stove chamber, and the utility model is provided with 2 to 6 groups of microwave feeding ports. The utility model is the sterilization dedicated microwave equipment of the foods with vacuum packing. The utility model can keep the given sterilization temperature within a certain time and have the good sterilization effect, in addition, the utility model can extend the sterilization time without the damage of the packaging bag.
Description
One, technical field
The utility model relates to a kind of food sterilization special microwave apparatus, the special-purpose box microwave equipment of especially vacuum-packed food sterilization.
Two, background technology
In order to store, to transport and selling, food must have certain shelf-life, so it is necessary that sterilization is a numerous food product, in the past, people use high temperature sterilization always, but high temperature sterilization can destroy the local flavor of product, be eliminated gradually, and microwave disinfection is being subject to people's attention as a new technology, but is in use it is found that, microwave disinfection remains in some problems, and these problems are:
Microwave can sterilization, but the uniformity of sterilization and continuation directly have influence on bactericidal effect.Food variety is a lot, different, not of uniform size, be applied to the sterilization of food industry as microwave equipment, must make each position of all processed food and same food be subjected to the processing of uniformity, otherwise will cause unstable product quality, general microwave equipment microwave introducing port all is arranged on the top or limit of treatment box, microwave can only enter treatment box from a direction, the fact shows, food in the treatment box absorbs more microwave earlier near the inlet portion branch of microwave, deep layer can only absorb less microwave, so different parts of food, surface and deep layer have a fairly obvious temperature difference, and the temperature difference that has reaches nearly 20 ℃, have so just seriously influenced whole bactericidal effect.
For preventing secondary pollution, product generally carries out microwave disinfection again after vacuum packaging.Make the temperature of bag interior food reach the temperature (general more than 80 ℃) of sterilization, in sterilization process owing to remain in air in the packaging bag swollen the rising that be heated, when temperature reaches more than 80 ℃, tend to occur rising a bag phenomenon, if continue to handle the bale broken pack of then can rising,, then can not keep the temperature of sterilization if turn off microwave at this point, if can not certain time, effectively the elimination of micro-organisms.Whether this does not just reach bactericidal effect, promptly neither destroy packaging bag and can prolong sterilizing time again and just become sterilization crucial completely so can continue sterilization.
Three, summary of the invention
The purpose of this utility model is: a kind of food sterilization special microwave apparatus is provided, and especially vacuum-packed food sterilization special microwave apparatus keeps the temperature of sterilization, can the effective the elimination of micro-organisms of certain time.Bactericidal effect is good, and lasting sterilization promptly neither destroys packaging bag can prolong sterilizing time again, guarantees the storage period of food.
The purpose of this utility model is achieved in that the special-purpose box microwave equipment of food sterilization, it is a kind of box microwave equipment, comprise rotating disk, leg, furnace chamber, switch, indicator lamp, observation window, microwave magnetron and feedback mouthful, it is characterized in that furnace chamber be provided with microwave magnetron feed-in mouth up and down simultaneously, and be provided with 2-5 group microwave magnetron feed-in mouth.Be one group one on the other.
And according to the distribution situation of microwave in treatment box, logical processed food places on the rotating disk on the best balanced plane, makes food temperature basically identical (general≤2 ℃) up and down after the sterilization processing.
Mechanism of the present utility model is: handle needed microwave emission measure down according to research one fixed load, result of study shows, the microwave of a M210 type magnetron emission can make meat, fowl, fish, bean product (because the differences such as water content of 3-3.5Kg, weight has a difference) keep sterilization temperature constant substantially, promptly vacuum-packed food can be handled and the bag that can not rise for a long time under such condition, and the processing time, long more bactericidal effect was good more.According to this achievement, many group microwave magnetrons are all worked during intensification, and food is heated to the desired temperature of sterilization (more than 80 ℃), and power is bigger, and processed food is heated up.And when insulation, only work with one group of microwave magnetron, have the radiation of microwave up and down simultaneously, guarantee uniform heating.
The course of work of the present utility model is: box-type equipment is magnetron grouping up and down then, respectively by different time relay control, open all magnetrons during intensification, when packaging bag rises by bag temperature reaching sterilization temperature, forward to and have only one group of work and be incubated, when not getting rid of the large volume case certainly with two groups of microwave magnetron work, the radiation that has microwave up and down simultaneously guarantees uniform heating.
Characteristics of the present utility model and innovative point are: this is a kind of food sterilization special microwave apparatus of vacuum-packed usefulness.The sterilization temperature of keep setting within a certain period of time, bactericidal effect is good, promptly neither destroys packaging bag and can prolong sterilizing time again.

Five, the specific embodiment
Magnetron adopts technical grade product, can continuous operation, and the power of every magnetron reaches 850W.
Magnetron adopts technical grade product M210 type magnetron, can continuous operation, and box can raise the rotating disk of loading of pieces, makes the food of placement be in the position of the lower middle of furnace chamber,
The box micro-wave oven one of present embodiment has three groups of 6 magnetrons, treatment box is respectively installed 3 up and down, respectively by three time relay controls, be that each relay is respectively controlled one group (every group up and down each a magnetron), work simultaneously for three groups during intensification, have only one group of work during insulation, the bag that neither rises can continue sterilization again, has received well-content bactericidal effect.Treating capacity reaches 500 kilograms/8 hours.
Be distributed in to the magnetron general equilibrium at the bottom of case top and the case.Becomes equilateral triangle when being provided with three magnetrons at the bottom of case top and the case, be distributed in the symmetrical position of geometric center at the bottom of case top and the case on every side.During four magnetrons with the geometric center be symmetric points rectangle or foursquare around on the summit.During five magnetrons, a magnetron is in geometric center, other four rectangle or foursquare around on the summit, surround the geometric center of symmetry.
By temperature controlling is realized heat up, the automatic control of temperature retention time is better.Automatic heat preserving when reaching sterilization temperature, i.e. control only is incubated magnetron work, the control of prolonging the sterilizing time that continues by PLC or CPU.
