  13. 13. Gherkins stowage Factor: 2 to 3 m3 per ton. 70 to 105 ft3 per ton. Gherkin Respiration rate: @ 10 °C, 60 watts per ton, 10 ml CO2/kg/h @ 15 °C, 96 watts per ton, 16 ml CO2/kg/h @ 20 °C, 141 watts per ton, 24 ml CO2/kg/h @ 25 °C, 168 watts per ton, 28 ml CO2/kg/h Gherkin Water Content: 96% water, Specific heat (kJ/kg/°C) 4.06 Gherkin Other Properties: Ethylene– Low Producer, Ethylene sensitivity – High, Freezes at -0.5 °C Ice Compatible – No, Optimal RH – 90 – 95%, Impact/Pressure sensitive. Gherkin Optimal Conditions: Stored at 7 to 12 °C / 90 – 95% RH, lasts from 10 to 14 days. Benefit of Controlled Atmosphere, Fair (+7 days). Sensitive to contamination by fats and oils.  Left unexposed in ambient, un-processed Gherkin will loose value within 24-30 hours. They are very susceptible to mold and other micro loads.  With proper post harvest care, Gherkins can last 10 to 14 days. Captain Pawanexh Kohli

Captain Pawanexh Kohli
  17. 17.  Though entirely design dependant, one large cart would use from 15 to 30 kgs of PCM (1.1 to 2.2 kWh of energy).  This would suffice between 12 to 16 hours of cooling or heating duration, with about 100 door openings of 10 secs each.  Any limitation in duration, would still bring benefits when compared to existing uncontrolled system.  PCM does not require any maintenance, has no machinery component, and simple to use once charged. Captain Pawanexh Kohli
  18. 18.  Improved design of on road street hawking carts.  No complicated machinery to confuse the hawker.  Reusable on a daily basis after recharging.  Provides aesthetics and hygiene to an age old retail business.  Allows the common hawker to compete with organised retail.  Reduces last mile wastage of food.  Brings viable and visible support to poor man – with the support of the government.
