The impact of AORODO technology on product quality
In the food processing industry, most of the reasons for the unqualified product quality are due to the fact that the total number of colonies exceeds the standard, mildew during the shelf life, and pathogens such as Escherichia coli exceed the standard. If these problems can be solved, the quality of the product will be greatly improved. No more fear of spot checks by the Food and Drug Administration. To solve these problems, the AORODO series ozone equipment can be used to effectively solve these problems.
As early as 1928, the British had used ozone disinfection in the egg-laying workshop of the "Hou Kee Egg Factory" in Tianjin, China . In recent years, the application of ozone sterilization technology in the food industry in China has been rapidly developed. Hai Kang adopted by the long AORODO technology ozone disinfection equipment R & D Technology Co., Ltd., is thriving, its efficient bactericidal properties, improve the quality of the food production of the product.
In food factories, ozone is very convenient and effective for disinfection in food processing rooms, storage rooms and processing equipment. As we all know, traditional chemical fumigation and UV disinfection have many disadvantages. Recent studies in foreign countries have proved that ozone is a good substitute for controlling airborne microorganisms . Through chemical atomization, ultraviolet light and ozone as a disinfectant control experiment, the conclusion is that ozone is effective and no residue. Ozone “suppresses†the growth of Escherichia coli and cocci in the processing equipment, effectively improving the product's qualification. Rate and quality.
The AORODO ozone generator can be placed directly in the air duct of the air conditioning purification system, called the built-in ozone generator. Ozone is sent to the clean areas along with the airflow of the air duct, and the clean area is disinfected and sterilized. The remaining ozone is sucked into the air return and taken away by the central air conditioner. The AORODO ozone generator can also be placed outside the central air conditioning vent, the ozone is driven into the air duct of the central air conditioner, and then sent to the clean area, called the external ozone generator. The disinfection effect is the same in both methods. According to the requirements of the Ministry of Health disinfection technical specifications, the ozone concentration for air disinfection is 5ppm, but in fact, the disinfection of the clean area is not only the disinfection of the air, but actually the disinfection of the surface of the object, so the concentration at the time of design Generally should be greater than 10ppm. Start up 1.5 to 2.0 hours before going to work every day, and start up for 1 hour after work, you can ensure that the floating bacteria and sedimentation bacteria in the clean area reach the requirements of SSOP and QS within one day.
From the test report of the food factory sterilized by ozone , it can be seen that the bacteria test is all qualified, and at the same time, the non-production work is reduced, the energy consumption is reduced, and satisfactory results are obtained.

PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
