The food quality challenge.
The main challenge for storage in refrigerated environments is maintaining the quality of the food, whether raw or processed.
"Refrigerated storage" is a great achievement, making it possible to face various aspects related to food perishability and deterioration. It is one of the most important weapons used in food technology, as it reduces production costs, improves food quality, reduces losses and waste, preserves tastes, flavors, colors and textures, as well as preserving the initial quality of these products.
However, if there is any Microbiological contamination within the refrigerated chamber, leading to a subsequent contamination of the stored food, this will generate a huge loss!
What are the main microorganisms present in the cold?
Fungus and bacteria.
Their presence produces odors that are similar to mold within the Chamber, which alters the surfaces of the stored carcasses, causing other problems.
The main bacteria present in cold environments is Psychrotrophic bacteria, which are organisms that are multiplied in the cold, producing enzymes that cause changes in meat and other foods. How about an example? Fat rancidification, defects and changes in product consistency, accompanied by exudation with the production of oily liquids (PRANDL-1994), in addition to modified product odors.
The main Psychrotrophic bacteria are the Pseudomonas, especially the fragile p. According to Prandl (1994) the proliferation of Pseudomonas and other Psychrotrophic bacteria in the Chambers is due to deficient hygiene processes and other aspects of environmental contamination.
Contamination may occur from Salmonellas (growth at 6C) due to cross-contamination, caused by storage with frozen poultry.
THE AIRFREE ® AIR PURIFIERS reduce an average 75% of the fungus and bacteria; drastically reducing organic odors; preventing cross contamination and promoting greater food durability.
In a test performed by AINIA-Instituto Tecnológico Agroalimentario, Valencia -Spain, an Airfree purifier was placed in a refrigerated chamber in order to test the effectiveness of the purification at 3°-5° C. In 15 days the concentration of fungus and yeasts was reduced by more than 86%.
How do they work?
They drastically reduce air microorganisms by incineration. As a result, the contaminated air is dragged into the Airfree ® ceramic center and destroyed at high temperatures. Organic particles that cause bad smells are also destroyed by this ceramic center, keeping the environment free from unpleasant odors. This air purification cycle is silent, requires no maintenance and is ensured by numerous tests.
AIRFREE ® CHARACTERISTICS:
Efficient - Tested and approved in real environments (no simulations) in the best institutes in the world. Airfree ® destroys any microorganism that passes through its ceramic sterilizer set, regardless of their dangerousness or size.
Silent - Absolutely no noise.
Exclusive - Internationally patented technology that is exclusive for Airfree ® products, the only one to also reduce ozone concentration.
Economic -There are no costs with exchanging parts nor significant power expenses, as the consumption of an Airfree ® is only 48w per hour.
Practical – Turn it on and don´t worry anymore, as the devices do not require any maintenance or cleaning.
No contraindications – Absolutely natural Process that does not use chemical or toxic products, neither radiation, and which also does not interfere in the temperature or humidity of the environment.
1. Are there any side effects?
No. Airfree’s new technology uses heat to purify the air. No side effects, no emissions, NO IONS, nor new particles are generated. Airfree® should be used in all homes and offices, quietly, constantly, and efficiently purifying the air.
2. Does Airfree eliminate bacteria and viruses?
Yes. Unlike the air filters in the market Airfree® is more efficient with the smallest microorganisms as they are easily carried by Airfree’s airflow into its heated ceramic core.
3. How does Airfree destroy dust mites?
Mould reduction in the environment causes reduction in the mould dependant dust mite population. Airfree also destroys the harmful toxins and fungus freed by dust mite feces that trigger respiratory allergies.
4. How does Airfree eliminate fungi?
As mentioned before, Airfree eliminates airborne microorganisms included fungi and spores. By eliminating spores new colonies are unlikely to develop, representing less future airborne spores.
5. How does Airfree® destroy viruses?
Those microscopic microorganisms are easily eliminated inside Airfree’s ceramic core capillaries. The temperature inside of Aifree’s capillaries is much higher than required to incinerate them. Airfree® is your greatest ally in respiratory disease prevention.
6. Does Airfree reduce tobacco smell?
Yes, Airfree reduces any kind of organic smell in the ambience including tobacco.
7. Does Airfree release any gas or chemical product?
No. Airfree’s sterilisation process is natural. Please check our website for conclusive tests regarding particles and ozone.
8. Does Airfree heat up a room?
No. Airfree does not noticeable increase room temperature. To have an idea 2 Airfrees plugged in the same room will contribute as much heat as the presence of one adult in that same room.
9. Does Airfree provoke any change in room’s the relative humidity?
10. Does Airfree need filter replacement?
11. Does Airfree consume a lot of energy?
No. Airfree’s consumption is just 52 Watts for P150, 50 Watts for P125, 48 Watts for P80, 45 Watts for P60, 50 Watts for E125, 48 Watts for E80 , 45 Watts for E60 and 40 Watts for E40.
12. Where do the microorganisms go after they are destroyed?
As all living organisms, microorganisms and their products are basically composed of carbon, oxygen and nitrogen. Since Airfree® reaches approx. 200º C, all the components are supposed to suffer a combustion process, which liberates carbon dioxide (the same product released by our respiration) and water. Some carbon (or ashes) may remain in the process. If there is some residual allergen left, we might consider that they suffer denaturation, a process resulting in loss of conformation and function. It should be noted that we are talking about reactions that occur in a microscopic level, so all these processes or by-products won’t be perceived. In this case, there is no need to worry about maintenance.
