New Technology High Efficiency Microwave Sterilization Equipment
Scope of application:
Microwave sterilization equipment is suitable for the sterilization
of various materials in the food field. Such as: condiments,
additives, chicken powder, meat products, fish products, seafood,
fruit pieces, beans, vegetables, mushrooms, flour, starch, rice
flour products, soy products, pickles, braised products, feed,
Nutrients and other materials.
Microwave sterilization can be divided into post-packaging
sterilization and pre-packaging sterilization. The packaging
container cannot be made of metal, and medium materials are
required. Generally, plastic flexible packaging or glass is used,
and engineering plastics are suitable. In order to prevent the bag
from expanding during the microwave sterilization process, the
equipment can apply pressure in the working chamber and adopt the
back pressure sterilization process, which can prevent the loss of
the bag from expanding.
Theory of Microwave Sterilization Equipment
Microwave sterilization is the result of the combined effect of the
thermal effect and biological effect of the electromagnetic field.
The thermal effect of microwave on bacteria is to change the
protein, so that the bacteria lose the conditions for nutrition,
reproduction and survival and die.
The biological effect of microwave on bacteria is that the
microwave electric field changes the potential distribution of the
cell membrane section, affects the concentration of electrons and
ions around the cell membrane, and thus changes the permeability of
the cell membrane. Therefore, the bacteria are malnourished, unable
to metabolize normally, the cell structure and function are
disordered, and growth and development are inhibited. And death.
In addition, the nucleic acid RNA and deoxyribonucleic acid DNA
that microwave can make bacteria grow normally and stably reproduce
is caused by several hydrogen bonds relaxation, breakage and
recombination, thereby inducing genetic mutation, or chromosomal
aberration or even breakage.
Features of Microwave Sterilization Equipment
1. Short time and fast speed
Conventional thermal sterilization transfers heat from the surface
of the food to the interior by means of heat conduction, convection
or radiation. It often takes a long time to reach the sterilization
temperature. Microwave sterilization is the direct interaction of
microwave energy with microorganisms such as food and its bacteria.
The thermal effect and non-thermal effect work together to achieve
rapid heating and sterilization, and the processing time is greatly
shortened. The sterilization effect of various materials is
generally 3-5 minutes.
2. Low-temperature sterilization maintains nutrients and
traditional flavors
Microwave sterilization is sterilization through special thermal
and non-thermal effects. Compared with conventional thermal
sterilization, the required disinfection and sterilization effect
can be obtained at a lower temperature and in a shorter time.
Practice has shown that the general sterilization temperature can
be achieved at 75-80 ° C. In addition, microwave-treated food can
retain more nutrients and flavors such as color, aroma, taste, and
shape, and has a puffing effect.
For example, the vitamin C retained by conventional heat-treated
vegetables is 46-50%, while that of microwave treatment is 60-90%,
and the vitamin A retention of conventionally heated pork liver is
58%, while that of microwave heating is 84%.
3. Energy saving
Conventional thermal sterilization often has heat loss in the
environment and equipment, while microwaves directly act on the
food, so there is no additional heat loss.
In addition, the conversion efficiency of its electric energy to
microwave energy is 70-80%, which can generally save 30-50% of
electricity.
4. Both the surface and the interior are carried out at the same
time
Conventional thermal sterilization starts from the surface of the
material and then transfers to the interior through heat
conduction. There is a temperature difference between inside and
outside. In order to maintain the flavor of the food and shorten
the processing time, the interior of the food often does not reach
enough temperature to affect the sterilization effect.
