Shock waves are natural phenomena typically associated with supersonic flows in the field of aerospace engineering. It is generally treated with a negative connotation due to its huge destructive potential.
However, the powers of the shock wave, if carefully harnessed, can be wielded with a positive flair in several applications spanning a large range of engineering and scientific disciplines. Notwithstanding being a focus of research for over a century, it is only in the last decade or so that shock waves have garnered the attention of scientists outside of the aeronautical field.
Shock wave treatment of organic material could be a potential game changer in the field from several angles. Treatment of various leaves with shock waves have been proven to effect a change in the chemical composition of the extract obtained, potentially increasing the market value.
Treatment of food and seeds such as tea , palm, sunflower, groundnut etc. can increase the yield of oil extracted. Shock waves can be used to improve the yield of fragrant materials from flowers to boost the perfume industry.
The industry applications of shock waves are still in quite a nascent stage. Pattern Intellectual labs and Srusti engineering are combining their energies for the right focused effort incubating several technologies which could change the entire outlook of the industry.
Treatment of Tea Leaves
- Removing as much moisture as possible before drying operation. As much as 50% reduction in withering time has been observed (physical wither).
- Enhanced poly amylase breakdown (chemical wither). Improves the taste, color and odor of the made tea
Lab Experiments
- Firing pressure in the range of 8 – 9 bar gave the best results.
