Description
Technical field
The invention belongs to active air conditioning agent field used in storage transport, be specifically related to the active air conditioning agent that a kind of controlled atmosphere attemperating unit is used.
Background technology
In recent years, growth in the living standard makes the requirement of people to food quality more and more higher, China is as agricultural product big producing country, Circulation of Agricultural Products amount is very large, annual about have more than 400,000,000 ton of fresh and live agricultural product to circulate field, 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, vegetable spoilage is up to 1.3 hundred million tons, direct economic loss about about 1,000 hundred million yuan, the fresh-keeping transport rate of fresh product is low, omnidistance temperature control transport is also far from meeting the demand of resident to fresh food.
Omnidistance temperature control comprises low temperature process, cryopreservation, low-temperature transport, low temperature sell four aspects.Wherein low-temperature transport is the link of most critical in omnidistance temperature control logistics.The low-temperature condition of the logistics links such as it comprises in food, 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 Three models such as the low-temperature transports of the low-temperature transport of low-temperature receiver, phase-change material for cold storage.Refrigerator car refrigeration low-temperature Transportation Model is mainly used in the long-distance transport of cryogenic cargo in enormous quantities, there is significant limitation in small lot, the dispensing of multiple batches of cold items.Portable heat-insulation box based on phase-change material for cold storage effectively can solve small lot, multiple batches of cold items dispensing problem.
In gas, the storage of ratio to fruits and vegetables and meat of the composition such as nitrogen, oxygen, carbon dioxide, ethene has a huge impact, about oxygenous 21% in normal atmosphere, carbon dioxide 0.03% and nitrogen 78%, suitable reduction oxygen content or increase the content of carbon dioxide, can T suppression cell respiration, Delay of ripeness ageing process, stop moisture evaporation, suppress the effects such as microbial activities.And oxygen and carbon dioxide controlled can obtain better fresh-keeping effect a suitable ratio.Temperature and humidity also plays very important effect in controlled atmosphere environment, and controlled atmosphere cold storage is fresh-keeping will regulate and control gas component concentrations needed for different category low temperature food product and strict temperature control and humidity, especially temperature, prevents too low the causing it of temperature from damaging 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, effectively can improve the controlled atmosphere environment in packaging, ensures 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 using active air conditioning agent in incubator.
Summary of the invention
