Description
Technical field
This patent belongs to far products storage fresh-keeping equipment, particularly a kind of antistaling box that carries out the fresh-keeping test of far products fruit storage.
Background technology
According to data, China's fruit and vegetable food has 20% ~ 35% wastage rate after adopting in storage fresh-keeping process, grain 8% left and right, this adopts rear far products merchandizing Preservation Treatment wastage rate with developed country and differs greatly compared with 5%, the loss causing is very surprising, visible, at the far products storing processing link in postpartum, also there is larger gap in China's relevant art research and application, carrying out this type of research has very important realistic meaning.
Far products is adopted rear fruit and is belonged to a kind of material with life entity feature, compared with other industrial products, requirement to storing processing environment is more strict, particularly fresh and alive fruit and vegetable food is extremely responsive to reserve temperature, and there is larger difference to temperature susceptibility in different products, except temperature, the conditions such as relative humidity, ventilation, gas ingredients formation and ratio, the temperature difference, illumination are also seriously causing approximately normal life metabolism.Such as, fruit and vegetable food adopt after because the imbalance of storage environment gas ingredients causes anaerobic respiration, causes the phenomenons such as temperature traverse that Chilling Injury, grain causes because moisture is higher all to show that storing processing link environment has very important relation to the maintenance of far products quality in postpartum due to the acute variation of the temperature difference, the discomfort of storing processing environment often causes the cataphoretic failure of later stage quality.
For far products quality in postpartum is kept, it is the research of test facility or device to storing processing link environment that scientific research personnel has carried out numerous, for far products storing processing provides essential parameter, conventionally sector-specific experimental set-up be need to develop and lab scale and pilot scale carried out, by lab scale and pilot scale, filter out storing environmental parameters, instruct and offer production practice and use.For fruit and vegetable food, for making test results reliable and practical, scientific research personnel has developed a series of storage processing experiment case both at home and abroad, its major part has casing (have insulation effect and there is no insulation effect), door (be with visual window and be not with visual window), refrigerating part (joining altogether refrigerating unit from supporting refrigerating unit with other casing), nitrogen pipeline processed (joining altogether nitrogen making machine from supporting nitrogen making machine with other casing), remove ethene pipeline (removing machine from supporting ethylene-removing machine with the common bivinyl of other casing), damping device (joining altogether nitrogen making machine from supporting nitrogen making machine with other casing), samming blower fan such device in case, part test case also only comprises with in upper-part several.In above proofing box, owing to having outfit refrigerating evaporator, so can cause spin manifold temperature to fall soon or rise soon, far products examination section product exposed in case strengthens because temperature fluctuation causes greatly percentage of water loss.
Therefore, as possessed temperature equalization in the urgent need to a kind of storage space, it is that temperature fluctuation value is little that heating and cooling have a narrow range of temperature, and observes product convenient, keeps relative humidity in case, possesses temp regulating function, and can carry out the proofing box of multiple kinds or kind.
This patent will be around overcoming the above problems, and designs a kind of proofing box of suitable farm produce storage test, can keep uniform temperature, relative humidity, possesses temp regulating function.
