Technology Use the Food

      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.
Enclose : DJ systematic ozone water equipment, is it is it disinfect DJ serial ozone ink equipment of water to make to use for, the density of ozone can reach above 2-10mg/1 , can deal with 0 per hour in water. Disinfectant of 5-5 tons, but consumption is 0. 6KW/m3. Serial products this of the equipment that the high density ozone that the DJ-Y series car person's our company researches and develops newly disinfects , this product produced the ozone of the high density through new-type and high-efficient PEM electrolytic water ozone generator, adopt two mix and two absorption make their shut with water elder brother, turn into high ozone water of density (disinfect the liquid ), can kill such bacteria as the colon bacillus , golden yellow grape ball ,etc. within 10 minutes and breed the body and destroy the antigen of second liver (HbsAg ) , dispel the peculiar smell, resolve such harmful substances as the agriculture chemical , chemical fertilizer ,etc. fast. The ozone that this equipment turns into disinfects the liquid can be up to 99 to the killing rate of bacterium of the object surface. 99%. To not dissolving into the ozone remained in the tail gas in water , get rid of through the effective device , make it bring ozone density to accord with national public place sanitary standard not to breathe, this equipment can apply washing with water before and disinfecting place to equipment , workingbench , pipeline , ware , tool , it is quick in speed to have having no secondary pollution , sterilization without residue, there are no dead angle , effectual , the equipment is small , low , steady reliable , easy characteristic of operating etc. of energy consumption.
