Storage of horticultural crops

  1. 1. PRESENTED BY: VAISHALI SHARMA B.Sc Ag 4th Year BHU
  2. 2. COLD STORAGE: • Storage at the temperature lower than ambient temperature • The fruits stored at low temperature exhibit more shelf life than those stored at ambient temperature.
  3. 3. 2. CONTROLLED ATMOSPHERE STORAGE: • The controlled atmospheric storage in higher CO2 and lesser O2 are maintained.
  4. 4. 3. MODIFIED ATMOSPHERE STORAGE SYSTEM: • Modified atmosphere is the practice of modifying the composition of the internal atmosphere of a package (commonly food packages, drugs, etc.) in order to improve the shelf life. • The need for this technology for food arises from the short shelf life of food products such as meat, fish, poultry, and dairy in the presence of oxygen.
  5. 5. 4.ATMOSPHERIC (HYPOBARIC STORAGE) • In this type storage life of several fruits and vegetables is increased significantly by reduced pressure under refrigeration, subsequently decreasing respiration and evacuation of ethylene given out by the produce.
  6. 6. 5. LOW COST STORAGE • Pusa zero energy cool chamber (pusa ZECC) can be constructed easily anywhere with locally available materials like bricks, sand, bamboo, khaskhas/straw, gunny bags, etc. with a source of water.
  7. 7. The main advantages: ➢It does not require any electricity or power to operate ➢Materials required like bricks, sand, bamboo etc. available easily and cheaply. ➢It is a double brick-wall structure, structure, the cavity is filled with sand and walls of the chamber are soaked in water. ➢ Even unskilled labour can build the chamber, as it does not require any specialized skill. ➢Cool chambers can reduce temperature by 10-15 degree C and maintain high humidity of about 95% that can increase shelf life and retain quality of horticultural produce. ➢ Small and marginal farmers can store a few days' harvest to avoid middlemen. ➢ Technology Vision 2020 has identified it as a low cost storage technology for 2020. ➢National Horticulture Board is giving 100% grant in aid for the benefit of the farmer.
  8. 8. Construction: • Select an-upland having a nearby source of water supply. • Make floor with brick 165 cm x 115 cm. • Erect the double wall to a height of 67.5 cm leaving a cavity of 7.5 cm. • Drench the chamber with water. Soak the fine river bed sand with water. • Fill the 7.5 cm cavity between the double walls with this wet sand. • Make top cover with bamboo (165 cm x115 cm ) frame and 'sirki' straw or dry grass. • At hatch/ tin shed made over chamber to protect from direct sun or rain or snow.
