304 SUS Tunnel Microwave Sterilizer Equipment For Chinese Herb
Scope of application:
Microwave Sterilizer Equipment can be used for drying and
sterilizing medicinal materials and pills, drying, sterilizing and
heating materials such as strips, blocks, granules, loose powders
and filter cakes with high water content and certain viscosity, and
sterilization of medicinal liquids. , sterilization before and
after packaging. It solves the problems that are difficult to
overcome by traditional processes. It heats up quickly, processes
materials quickly, and improves work efficiency; it realizes
low-temperature sterilization without damaging the active
ingredients of medicine; it can be heated through packaging to
improve product quality: no waste water or waste gas is generated.
, waste residue, environmental protection and energy saving.
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 Machine
A large number of facts show that the drying and sterilization of
Chinese medicinal materials by microwave is much better than the
traditional high-temperature drying and sterilization process. The
microwave drying and sterilizing machine for Chinese medicinal
materials uses the electromagnetic induction of microwaves to heat
and dry the materials. Different from other external heating drying
methods, this drying method is to heat uniformly from the outside
and inside of the material at the same time. Therefore, this drying
treatment method has a short time and will not be deteriorated or
coked due to overheating. The quality of the dried products is
good, especially The drying effect of heat-sensitive Chinese
medicinal materials is satisfactory.
The latest microwave drying and sterilizing machine for Chinese
medicinal materials is a conveyor belt continuous dryer with
multiple drying chambers, each with a microwavesource, make the
microwave field radiate evenly in the room, and at the same time
there is a dehumidification device, and multiple exhaust pipes are
collected together to dehumidify. In a separate console, various
process parameters can be set, and there is a long resister to
prevent microwave leakage. There are observation doors on the side
of each drying chamber. The main features of the machine are as
follows:
1. Compared with the existing equipment, the composite structure
can save energy by 10%~20%.
2. Multi-microwave tube feeding makes the temperature of the
conveyor belt surface in the drying chamber uniform, and the
conveyor belt is vertical.
3. The microwave tube (magnetron) is cheap and has a long service
life, up to 1 year.
4. The temperature of the outer surface of the furnace is low, and
the operating environment of the workers is good, which is both
energy-saving and environmentally friendly.
5. The transmission speed is 0~20m/min, and the speed is controlled
by frequency conversion.
