Description
Technical field
The present invention relates to a kind of microwave sterilization machine and its application methods, belong to food sterilization equipment technical field.
Background technique
Food easily contamination and deterioration in production, preservation, transport and sales process.High temperature can usually be used, drying, scalded
The routine techniques such as drift, pasteurization, freezing and preservative come realize to the Pesticidal and sterilizing of food with it is fresh-keeping, but often influence food
The original local flavor and nutritional ingredient of product.Microwave heating effect is microwave and material direct interaction, and uhf electromagnetic wave is converted
For the process of thermal energy.Microwave disinfection is microwave heating effect and the coefficient result of biological effect.Microwave is to bacterial membrane section
Potential distribution influences cell membrane ambient electron and ion concentration, to change permeability of cell membranes energy, therefore nutrition is not or not bacterium
It is good, it is unable to eubolism, the interrupted death of growth and development.Therefore, for the sterilization of field of food, at microwave
Reason, can realize good bactericidal effect in the case where not influencing flavour of food products.
Summary of the invention
For overcome the deficiencies in the prior art, the first purpose of this invention is to provide a kind of microwave sterilization machine, this sets
Standby that sterilization processing can be carried out after food packaging, process is simple, high-efficient, lowers the influence to flavour of food products.
Second object of the present invention is to provide a kind of application method of above-mentioned microwave sterilization machine.
Realize that the first purpose of this invention can reach by adopting the following technical scheme that: a kind of microwave sterilization machine, packet
Include conveyer belt, the first microwave absorbing device, microwave treatment area, the second microwave absorbing device and seal case；First microwave absorption
Device, microwave treatment area and the second microwave absorbing device are according to conveyer belt transmitting path sequential；Microwave treatment area is set to close
In joint sealing body；Microwave generator is equipped in microwave treatment area.
Further, conveyer belt at least one is parallel to each other between each conveyer belt.
Further, the travelling speed of conveyer belt is 1.5-2m/min.
Further, the first microwave absorbing device and the second microwave absorbing device are graphite microwave absorbing device.
Further, the microwave wavelength that microwave generator is issued is 800MHz~100GHz.
Further, the microwave wavelength that microwave generator is issued is 20GHz~80GHz.
Realize that second object of the present invention can reach by adopting the following technical scheme that: a kind of microwave as described above
The application method of sterilization machine includes,
Starting step: seal case is completely closed, the first microwave absorbing device of starting, microwave generator and the second microwave
Absorption plant；
Sterilisation step: the food to be sterilized with packaging is put on conveyer belt, microwave treatment area is conveyed through and sterilizes
Afterwards, communicated band is sent out.
Further, the travelling speed of conveyer belt is 1.5-2m/min.
Further, the length in microwave treatment area is 1-3m.
Further, the microwave wavelength that microwave generator is issued is 20GHz~80GHz.
Compared with prior art, the beneficial effects of the present invention are:
1, microwave sterilization machine of the invention can carry out sterilization processing after food packaging, and process is simple, high-efficient, lower
Influence to flavour of food products；
2, the microwave sterilization machine of the invention electromagnetic field very high using the thermal temperature field of microwave and the frequency of electromagnetic force
It is sterilized, cell membrane ambient electron and ion concentration is influenced on the Potential distribution of bacterial membrane section, to change cell membrane
Transparent performance, bacterium is therefore malnutritive, is unable to eubolism, the interrupted death of growth and development.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
In figure, 1, conveyer belt；2, the first microwave absorbing device；3, microwave treatment area；4, the second microwave absorbing device；5, close
Joint sealing body.
Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
Embodiment:
Referring to Fig.1, a kind of microwave sterilization machine, including conveyer belt 1, the first microwave absorbing device 2, microwave treatment area 3, second
Microwave absorbing device 4 and seal case 5；First microwave absorbing device 2, microwave treatment area 3 and the second microwave absorbing device 4 are according to biography
Send band 1 transmitting path sequential；Microwave treatment area 3 is set in seal case 5；Microwave is equipped in microwave treatment area 3
Device, the microwave wavelength that microwave generator is issued are 20GHz~80GHz；Conveyer belt 1 be at least one, each conveyer belt 1 it
Between be parallel to each other, germicidal efficiency can be improved in the transmission parallel of a plurality of conveyer belt 1；First microwave absorbing device 2 and the second microwave are inhaled
Receiving apparatus 4 is graphite microwave absorbing device, for absorbing microwave.
The application method of microwave sterilization machine, including,
Starting step: seal case is completely closed, the first microwave absorbing device of starting, microwave generator and the second microwave
Absorption plant；
