Cold Store & Ripening Chamber Climate Monitoring & Automation System:

Cold Store & Ripening Chamber Climate Monitoring & Automation System www.ekeindia.com E: [email protected] Mobile: +91-96809 66000 (India) 1 EK Engineering (India) Climate Control and automation system

Topics covered::

Topics covered: Why gas monitoring is needed Importance of proper ventilation for long-lasting, fresh & safe products Monitoring parameters Horticulture cold stores monitoring Ripening chamber monitoring Meat etc processing and cold stores Topology of the system and component integration www.ekeindia.com E: [email protected] Mobile: +91-96809 66000 (India) 2

Need of Gas Monitoring::

Need of Gas Monitoring: www.ekeindia.com E: [email protected] Mobile: +91-96809 66000 (India) 3 CO 2 Monitoring : Agriculture and horticulture products produce CO2 (carbon dioxide) gas during breathing. High CO2 concentration reduce breathing, thereby form dull & wrinkle skin, low skin shine, high sweetness (specially in case of potatoes etc). Reduce product weight, market price. High CO2 also reduce O2 concentration resulting in anaerobic decomposition. Low O2 also cause darkening of potato chip colour, ultimately result in decay of interior cell with black heart.

Low O2 cause anaerobic fermentation, skin wrinkle, black skin spots, reduced shining of peel skin Reduce moisture contents Reduce weight Reduce quality

Ammonia is very toxic gas for biological life and human and life threatening with TWA = 25 ppm Ammonia leakage can percolate to stored items and thereby enter food chain. Ammonia can damage with corrosive effect on stored items

Freon leakage can sometime lead to fire, causing considerable damage to assets.

Low ethylene concentration cause under-ripening, hence low market price of the products, while high ethylene concentration can damage products, increasing spoilage.

Low temperature will freeze up the inside content and reduce natural sweetness and taste, sometime forming carbohydrate, sucrose crystals High humidity will increase moisture content in the stored items, leading to bacterial and worm formation. Sometimes, dew formation also lead to considerable spoilage. Low humidity will reduce weight, sweetness, natural flavour and increase in rejection
