Ozone is in
the field of application of the food trade |
|
The ozone
gains the name with its peculiar smell , it is the strong
oxidant of a kind of gas, have sterilization to be strength
strong , produce any remain pollution is can directly to
food person who use advantage. As one wide table
high-efficient bactericide, sterilization its speed 300-600
times faster chlorine have relatively , can kill various
kinds of bacteria breed body and gemma , virus and fungi
fast, for instance colon bacillus , salmonella , golden
yellow staphylococcus , withered grass bacillus black
mutation gemma , black aspergillus , hepatitis B surface
antigen ,etc.. The ozone is extremely unstable, can resolve
into oxygen by oneself , does not produce any to remain .
The earliest test that the ozone is used as the bactericide
was carried on smoothly in France then by Mei Li in 1886
years, the earliest instance is that the cold storage plant
of Cologne of France utilized ozone to disinfect in
refrigerating the beef surface in order to improve and
preserve one in 1909. In recent years, the application in
the food trade of ozone gets the fast development, among
1995-1996 years, Japan , France , Australia legislate in
succession, allow the ozone to use extensively in the food
trade. |
 |
In April of 1997, American food and medical
administration bureau (FDA ) gave up using the restrictive
policy of the ozone to food processing , acknowledge the
ozone and apply to accord with demand of GRAS (the safety
standard in common use ) in food course.
|
|
In 1928, Englishmen set up " writing the egg factory
jointly " in Tianjin of our country, the workshop utilized
ozone to disinfect if it beat eggs. Will it be the end
1930s, U.S.A. 80% cold-stored egg storehouse equip with
ozone generator , raise storage issue of egg. By middle
period of 1990s, of our country much Sino-foreign joint
venture food enterprise, sterilization in workshop purify,
perishable freshness , link , warehouse of storage and cabin
,etc. of food of food install the ozone generator, and then
popularize to food container , food and refrigerate the
workshop again. |
|
Cause the attention of the food pollution as people
remain the chemical disinfectant, the new developing
disinfectant that the ozone will become the food trade gets
fast popularization and use. |
|
Though the medicines in our
country have produced GMP and already recommended the ozone
sterilization method while verifying, but the application
that the ozone born in the food is that had not got a chance
of flourishing development in the past two years. The
following several respect mainly use success: |
|
(1) Processing workshop(storehouse) with process to
disinfect sterilization equipment
In food factory, ozone gas use food processing, stock room
and process equipment it disinfects to be very convenient
effectual. The method is to use such chemical reagent as the
formaldehyde ,etc. stiflingly that the ones that spread
disinfect , as everyone knows, there are more stifling
disadvantages of formaldehyde, studying recently abroad
proves, in controlling the air microbially, the ozone is the
substituent of formaldehyde and smoked pharmaceutical of
other chemistry. Test through chemical atomization ,
ultraviolet ray and contrast of making disinfectant of
ozone, the conclusion is that the ozone is effective and
without residue, the ozone has " suppressed greatly" and
processed the growth of the a group of small coccus of colon
bacillus and saccharomycete in the equipment. |
|
Its method is to join the ozone generator outside the
new draught of the central air conditioner directly, the
ozone is sent in the tunnel of the central air conditioner
through the vortex air blower of the new draught, then sent
into every clean district. Disinfect demand of technical
specification according to Ministry of Public Health,
density 5ppm to air disinfecting ozone, but in fact, to it
disinfects to be not only to to disinfect air clean
district, including superficial to disinfect to object also
in fact,so, the |
 |
|
densityat the time of the design should
generally be greater than 10PPM. Start the machine 1 before
going to work every day. 5-2. One hour, start the machine
one hour after coming off duty , can guarantee one day clean
district swim fungus and subside fungus meet the requirement
of SSOP. |
|
Can be seen from the examining report using the ozone
to carry on the food factory of sterilization, it is all
qualified that the fungus is examined, have totally
substituted the troubling formaldehyde and disinfected
stiflingly and greatly. Meanwhile, enabled not reducing by
the production operation, energy consumption reduces, make
out the satisfactory result.
For having no vent or only entering the draught , did not go
back to clean district of the draught , experiment examining
area ,etc. , air , FD-Q-H of brand , that company is design
for this specially disinfect special-purpose series of
products , can convey ozone to each place of space rapidly,
the computer controls regularly, there is not the dead angle
, easy to move to use, can reach cleanliness of one hundred
grades .
|
|
(2) Sterilization of the disinfecting of space
Quick-frozen food , cold milk product , product of diet and
egg of meat process workshop and packing shop utilize ozone
disinfect effectual. At the same time , can get rid of the
peculiar smell to pollute . Generally (0. 5-1.
0)*Disinfecting rate of air that 10-6 ozone can be more than
80%. Whether in workshop of 150m3, ozone disinfect 2h
(4*10-6 density about to estimate ozone ) contrast the data：
It is at air it is before disinfecting in bacterium total
amount (piece / m3 ) /after not disinfecting
Cool one 105/26
Packaging one 1325/0
To the clean district beyond the cleaning system of central
air conditioner , or need other rooms of sterilization to
need to deal with sterilization alone. The method is to
select the ozone generator for use, install in this room
directly. Establishing the time of disinfecting according to
the need, disinfecting finishes automatic shut-down, so it
is very convenient to use. Use according to the selecting
type of size of the volume of room space. So long as meet
the demand for the density of ozone , can achieve and
disinfect the purpose of sterilization . Than with saving
trouble stiflingly manily to the room of chemical reagent ,
can totally replace chemistry stiflingly , shorten the time
of disinfecting, avoid the secondary pollution.
(3) The surface of articles disinfects and sterilizes
In the course of food production , should often carry on the
object surface and disinfect to raw materials , tool
apparatus , packing article , production place ,etc..
Traditional method to disinfect with ultraviolet ray ,
disinfect thorough degree, is it disinfect the dead angle to
store in, decay fast, all sorts of drawbacks of killing etc.
that to some bacteria in the specific environment unable.
Introduce in " technical specification that disinfect ", the
object surface to the submergenc in the ozone body, keep in
touch for some time, can kill the surface bacterium .
Enclose : Brief introduction of serial products of air
cleaning sterilization
It accords with the standard of " technical specification
that disinfect " of Ministry of Public Health that the
company develops two major series of ozone products of the
balance . Products that the series of air cleaning combined
multiple technology and developed and developed among them,
can totally meet the demand for sterilization to
disinfecting of authentication of food trade " SSOP " . DJ-Q
, FD-Q (A ) , (H ) series machine. Series machine this have
have long performance life , structure succinct light
installing and is it it uses to be extremely getting
convenient characteristic to speak complete machine.
Scope of application：
1. Cooperate with the air conditioner to purify systematic
DJ-Q series of ventilation (HVAC )：Series of products this
adopt electrolytic aquatic products technology to catch
ozone , have ozone to be density high (discharge 3 times ,
law of ozone for routine), being heavy, output make air
disinfect sterilization and process workshop to be heavy to
disinfect;
2.FD-Q (A ) series: Adopt 15000V cold cathode aura discharge
technology, have large ozone output function , can cooperate
with air conditioner purify ventilation (HVAC ) system or
special-purpose air is it disinfect with conveyer to the big
workshop to disinfect;
3.FD-Q (H ) hanging series: Used in some and separate room
sterilization(air and surface), including control zone
packing shop facility ,etc. disinfect sterilization .
4) Sterilization of the disinfecting of food
equipment，container , tool , production process |
 |
While beverage , fruit juice,etc. produce, the
ozone and water can be used in the pipeline , produce the
soaking and washing of the equipment and splendid attire
container , thus achieve and disinfect the purpose of
sterilization . Hold and using the method with this kind of
one that soaks , washes , first, pipeline , equipment and
containerbacterium |
|
virus on the surface of splendid attire are washed and
drenched in a large amount; Second , remain it in killing by
the ozone by bacterium , virus washed away on the surface, save
trouble briefly very much, and will not produce the dead
angle in production , totally avoided such questions as
chemical poison and material using the chemical disinfectant
to bring are discharged and remaining while producing yet.
In addition utilize ozone water to to disinfect
sterilization technology combine membrane separate the craft
, aseptic filling system ,etc. production equipment ,etc.,
the production used in the soy sauce , vinegar and drinks in
making industry, can improve the quality and grade of the
products .
The application in the vegetables are processed, for
instance in the food processing such as traditional hot
pickled mustard tuber , turnip , small cucumber of inner
wrapping vegetables, a lot of enterprises adopt and pack the
craft that the back high temperature disinfects frequently
in order to lengthen quality guarantee period of the
products, so not merely color and luster , quality to the
products ,etc. have brought unfavorable influence, and has
also consumed a large amount of energy. Utilize the ozone
water-cooling sterilization new technology to avoid the
adverse effect that the traditional processing technology
bring to product quality, and can improve product quality ,
reduce the production cost.
The application in the aquatic products products are
processed, while dealing with before the freezing of frozen
aquatic products, disinfect and can play a good control
arrivesing role to the hygiene index of making the products
of water through the ozone water spray.
There are three respects mainly in the application in the
freezer: First , kill the microorganism - disinfect and
disinfect; Second , make various kinds of inorganic matter
or organic matter with stink oxidize and deodorize ; Third ,
make the metabolism result oxidize , thus suppress the
metabolism course.
