Tea Fermentation

Benefits of Super-Oxidation (Ozonation) in Tea Fermentation :

Firstly, Ozone is the strongest natural disinfectant gifted by Mother Nature. It is exactly 3157 times stronger than Chlorine.
For tea fermentation, since increasing the oxygen at the time of fermentation is all the most essential, air is blown at a high rate through funnels at the bottom of the slowly moving table with tea leaves on it, as per backdated process, to forcibly oxidise the tea. It is understood that the prime purpose is to provide as much oxygen within the limited time.

Now, Ozone has a typical technical advantage in improving the fermentation of tea. Ozone is an allotrope of oxygen with no other toxic or foreign molecule attached to it. Its oxidising capacity is more than 5.5 times that of pure oxygen.

Normally, air is blown at CFM, containing only 19% humid oxygen. Therefore if air is mixed with Ozone, oxidation potential increases substantially.

And due to high disinfection property of Ozone, there's zero risk of contamination on the surface of tea leaves during production & packaging, when the machines are implemented accordingly.

  • Enhancement of Tea Quality
  • Absolute Disinfection of tea leaves
  • Within 60 minutes of slow fermentation with ozone, experience a stronger liquor
  • Increased Production in lesser time
  • Higher liquor strength shall obviously earn distinction from others & you can charge a higher price
  • Provides much greater oxygen to tea, for quicker & more efficient Fermentation process
  • Save processing costs in fermentation
  • Reduction of Wastage
  • Zero toxic residue
  • Absolute Infection-Control of tea leaves
  • Original flavour is kept intact
  • Enzymatic values are fully retained
  • Hidden pest / toxicities completely destroyed

For ease of calculation, say the processing is for around 1000 Kg of tea per day. If the operator is increasing the selling price by only ₹2 per Kg after strengthening the liquor by ozone treatment, the operator is making ₹2000 extra, per day (₹60,000 per month) . Therefore, the cost of the ozone equipment is returned in only a few months of operation.

For disinfecting the equipments used in processing, hot water with chemicals is generally used, consuming a large amount of energy and chemicals. The use of ozone considerably lowers chemical costs and completely eliminate hot water costs on industrial sterilization.

For project implementations, we need the following information, as per your processing design implemented at your factory :-

  1. CFM Capacities of your Oxidation blowers
  2. If you're implementing Floor-fermentation, then what is the square-feet area of that floor(s)?
  3. How many cubic feet of air is coming via your ducts / humidification system?
    This air is to be Ozonated, as it spreads on the fermentation beds and helps the super-oxidation & disinfection.
  4. Total square feet area of your processing & packaging sections
    For calculating the alternative portable models - for the same utility
  5. Details of CTC machines, for fighting the bacteria formation through the air cooling ducts to the cutting rollers.
  6. For surface disinfection of production equipment with Ozonated water :
    a. What is the length of each equipment that is disinfected
    b. Number of equipment to be disinfected
