Description
Technical field
The invention belongs to active air conditioning agent field used in storage transportation, be specifically related to a kind of controlled atmosphere attemperating unit active air conditioning agent used.
Background technology
In recent years, growth in the living standard makes people more and more higher to the requirement of food quality, China is as agricultural product big producing country, Circulation of Agricultural Products amount is very large, approximately there is every year more than the 400000000 ton of fresh and live agricultural product field that circulates, but fresh food is easily putrid and deteriorated, very high to the temperature requirement in transportation, the meat that China is annual, the fresh and live agricultural product proportion of goods damageds in postpartum such as aquatic products are up to 25%～30%, fruit rots nearly 1,200 ten thousand tons, vegetables are rotted up to 1.3 hundred million tons, approximately 1,000 hundred million yuan of left and right of direct economic loss, the fresh-keeping transportation rate of fresh product is low, omnidistance temperature control transportation is also far from meeting the demand of resident to fresh food.
Omnidistance temperature control comprises low temperature process, cryopreservation, low-temperature transport, four aspects of low temperature sale.Wherein low-temperature transport is the link of most critical in omnidistance temperature control logistics.It comprises food in, the low-temperature condition of the logistics link such as long-distance transport and short distance dispensing.Current omnidistance temperature control logistics transportation mainly comprises: refrigerator car low-temperature transport, using dry ice etc. as the low-temperature transport of low-temperature receiver, three kinds of patterns such as low-temperature transport of phase-change material for cold storage.Refrigerator car refrigeration low-temperature Transportation Model is mainly used in the long-distance transport of low temperature goods in enormous quantities, for small lot, multiple batches of cold items, on providing and delivering, has significant limitation.The phase-change material for cold storage of take can effectively solve small lot, multiple batches of cold items dispensing problem as basic portable heat-insulation box.
In gas, the ratio of the composition such as nitrogen, oxygen, carbon dioxide, ethene has a huge impact the storage of fruits and vegetables and meat, approximately oxygenous 21% in normal atmosphere, carbon dioxide 0.03% and nitrogen 78%, the suitable content that reduces oxygen content or increase carbon dioxide, respiration, Delay of ripeness ageing process, the prevention moisture that can suppress cell evaporate, suppress the effects such as microbial activities.And oxygen and carbon dioxide are controlled to a suitable ratio can obtain better fresh-keeping effect.Temperature and humidity also plays very important effect in controlled atmosphere environment, and controlled atmosphere cold storage is fresh-keeping will have been regulated and controled the required gas component concentrations of different category low temperature food products and strictly control temperature and humidity, especially temperature, prevents from that temperature is too low it is caused and is damaged to plants caused by sudden drop in temperature.It is one of current the most effective fruit and vegetable fresh preservation method of generally acknowledging in the world that controlled atmosphere combines with refrigeration.
At present, active air conditioning agent mainly contains the classes such as carbon-dioxide absorbent, release of carbonate dioxide agent, deoxidier, ethylene scavenger and control humectant.Active air conditioning agent is applied to active packing aspect mostly, can effectively improve the controlled atmosphere environment in packing, guarantees quality and the quality of fruits and vegetables, extends storage period and the shelf life of fruits and vegetables.Existing incubator only has heat insulation function, without controlled atmosphere function, and at present temporarily without the case of using active air conditioning agent in incubator.
