Technical Support Microwave Sterilization And Dryer 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. Microwave sterilization equipment can selectively heat
materials:
Microwaves have different effects on different substances, which is
beneficial to drying. Microwaves are better absorbed by dry water
molecules, and the high-moisture part absorbs more microwave power
than the low-moisture part, which is characteristic of selective
heating. This feature allows for uniform heating and drying when
microwaves are used to process bulk, cardboard, etc. products.
2. Microwave sterilization equipment is energy-saving and
efficient:
In microwave heating, the microwave energy can only be attracted by
the heating object itself to generate heat, and the heating chamber
wall and the air in the heating chamber and the corresponding
container do not generate heat, so the thermal effect is high and
the effect is significantly improved.
3. Short time and fast speed:
Microwave uses its selective transmission effect to make food
uniform inside and outside, and quickly heat up to kill bacteria.
Processing time is greatly reduced. Satisfactory results can be
achieved even in a few seconds or tens of seconds at high power
density.
4. High efficiency, energy saving and convenient operation
