Application on catering industry:
The advantages of ozone application in catering industry:
The advantage of Ozone disinfection in the catering industry: flexible, low cost, obvious effect, and without negative effect;
Ozone sterilization method :
1#: Cleaning and Soak in the ozonated water; 2#: Air disinfection and air purifying
The advantage of Ozone disinfection:
1#:Not only can the tableware disinfection, but also has others function which others normal disinfection equipment do not possess (disinfection ability of catering area and kitchen equipment), degradation of harmful residues in fruits
and vegetables contain pesticides and hormones in meat products, avoid the occurrence of food poisoning.
2#:Ozone can be directly to the kitchen, dining room, refrigerator, the knife dish rack, breeding, storage room
disinfection, and ozonated water disinfection could be used also.
3#: Ozone or ozonated water can be used for plastic, porcelain products which cannot be disinfected under
the high-temperature.
4#: Adopt the ozonated water to wash vegetable, fruits and meat could degrade the harmful hormone
degradation and the pesticide residues.
Ozone disinfection required for a short time, simple operation, after disinfection without cleaning;
the 100 pieces of tableware disinfection (dinner for 8-10 person):
1#: The conventional procedure with others disinfection equipment need about 140 minutes, the process
is as follows:
Decontamination (15 minutes); Poison cleansing soaking: (90 minutes) ; cleaning (15 minutes); disinfection cabinet (20 minutes);
2#: Using ozone disinfection, generally required 38 minutes only. The process is as follows
Decontamination (15 minutes); cleansing (15 minutes) ; Poison cleansing soaking(8 minutes);
3#: Using ozonated water disinfection require 30 minutes only. The process as following:
Decontamination (15 minutes); Poison cleansing soaking (15 minutes);
There are no harmful residues, and no secondary pollution for environment.
Ozone will automatically decompose into oxygen, no smell, no pollution, and disinfection is complete, good effect.
Ozone disinfection lower cost
Ozone disinfection mainly to use the air as raw material, the power consumption is much lower than the disinfection cabinet,
the tableware can be directly used without drying
Ozone sterilization principle can be thought of as an oxidation reaction.
1#:Mechanism of ozone on bacterial inactivation:
Ozone on bacterial inactivation reaction is always very rapidly. Unlike other fungicides: ozone can react with the
bacterial cell wall lipids double bond, the internal bacterial penetration, in the role of protein and lipopolysaccharide,
change cell permeability, resulting in the death of bacteria. Ozone is in the role of nuclear material within cells,
such as nucleic acids in DNA purine and pyrimidine destruction.
2#:Mechanism of ozone on virus destruction:
Effect of ozone on the virus is the first of four peptide chains virus coat protein of the clothing, and RNA by injury.
Phage has been oxidized, the observation that its skin was broken into many fragments, which release a lot
of ribonucleic acid interference, its adsorption to storage body. Ozone sterilization is complete beyond doubt.
Application Standard:
Ozone concentration use on Space purifier, equipment, Container disinfection, fresh keeping,
odour removal (1PPM=2.14mgL);
1#: Provisions of China's Ministry of health in 1979 formulated the "industrial hygiene standards", safety standard
for ozone is 0.15ppm.
2#:The United States standards, staff can work 8 hours at a concentration of 0.1ppm. (General forest area of
ozone concentration reached 0.1ppm)
3#: The provisions of the International Ozone Association, the professional application of ozone in indoor,
concentration of 0.1ppm,allowed to work 10 hours
4#: The concentration of 0.5-1ppm caused staff reaction, allows the contact time is 1.5 hours, will feel dry
and discomfort if contacted for a long time
5#:1-4ppm of concentration will cause people cough, allows the contacting time of 1 hours.
6#: 4-10ppm of concentration will cause the strong cough, allows the contacting time of 20 minutes
7#: The half -life of Ozone is 20-50 minutes. Break down to be oxygen finally. So there are will be no any
residual or contamination for food.
8#: Practice has proved that to use ozone for disinfection, mold for many years. There are no any equipment
or material damages to be found.
