China Price Professional Supplier Microwave Drying And
Sterilization Machine
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. Easy to control
Microwave food sterilization treatment, the equipment can be used
immediately, without the thermal inertia of conventional thermal
sterilization, flexible and convenient operation, the microwave
power can be continuously adjusted from zero to rated power, and
the transmission speed can be continuously adjusted from zero,
which is easy to control.
3. Simple equipment and advanced technology
Compared with conventional disinfection and sterilization,
microwave sterilization equipment does not require boilers, complex
piping systems, coal yards and transportation vehicles, etc., as
long as the basic conditions of water and electricity are
available.
4. Improve working conditions and save floor space
The working environment of the equipment is low in temperature and
low in noise, which greatly improves the working conditions.
