20/4/2014 Controlled atmosphere and long term preservation of fruits http://www.van-amerongen.com/ES/Atmosfera-controlada_40_34_6.html 1/2 News World wide Login FAQ Controlled Atmosphere Vegetables and fruits breathe; take oxygen (O2) and expel carbon dioxide (CO2). Preserving fruits and vegetables in an airtight enclosure, oxygen levels in the atmosphere are reduced by increasing levels of CO2. The long-term preservation of vegetables and fruits is to counteract the maturation and aging, preserving the taste and quality. In fact, what is done is delay ripening. This is achieved by adjusting the gas conditions in the cold room, thereby reducing the respiration of fruits and vegetables. Controlled Atmosphere (CA) storage is a technique that reduces the levels of oxygen and increased levels of CO2. Under conditions of controlled atmosphere, quality and freshness of fruits and vegetables without using chemicals remain. A large number of products can be maintained under conditions of AC at 2 and 4 months time. What do you need for conservation in AC? CO2 treatment plant The plant CO2 serves to regulate the levels of CO2 in the cold room. The storage room air is passed through the purifier, returning purified air CO2. Read more about our CO2 purification Purifying O2 O2 With a treatment plant (also called oxygen generator or separator) fruit quickly recovers AC condition after filling the storage enclosure, or when a door is opened.

The catalyst for ethylene Van Amerongen removes ethylene from cold storage based on catalytic combustion; thus, the ethylene is reduced to the desired levels. [Read more about our catalysts ethylene] • Controllers Controllers measure and record levels of O2 and CO2, these gases sent to the treatment plant. And with one controller can regulate the cooling (on and off, control defrost control, the engine room), as well as measuring the ethylene and ethylene control catalyst.
