Spirit adjusts hoarding to mean under the feat low temperature condition, the change stores environment air a kind of hoarding way of the composition.Speak on the broad sense that annoy adjusts hoarding to include self-moving spirit to adjust a hoarding method with can control spirit to adjust a hoarding method 2 kinds.The former means to seal completely fruit Shu in the plastics thin film of have the well ventilated function or take the plastics thin film bag or debt of Huo window, make use of the well ventilated of the function and plastics of the fruit Shu oneself breath, at must under the temperature condition, self-moving regulate the content of the O2 and the CO2 in the closeness environment, make it suit the request that the spirit adjusts hoarding, call MA hoarding.For example the plastics thin film big debt method, the Huo gum window thin film close a method etc.;The latter points to seal completely fruit Shu in the airtight spirit adjust the room(or database), make use of the fruit Shu breath function, and adopt machine spirit to adjust an equipments, regulate to the O2 and the CO2 air artificial in the closeness system the feat air constitute of hoarding method.Because the former mainly depends on fruit Shu the breath function of the oneself to carry on air to regulate, therefore main feat store at the short date, opposite latter hoarding the effect be worse.The spirit that we generally point adjusts to store to then point the latter, so our point talks the latter.Everyone should first what to notice's being a spirit to adjust to store don't point simplicity to regulate air, but the establishment regulate in the air under low temperature condition.
A, the main facilities annoyed to adjust to store
(A)The spirit adjusts a database
Spirit's adjusting a database is a foundation in traditional fruit Shu cold database to develop of, therefore and on the other hand it equally requests what cold storage have usually goodly separates heat and defends tide;Annoy to adjust the characteristics that the database body has an oneself on the other hand, most of be request a database body to have to annoy airtight, the purpose is with the commutation of decrease and the external world air, for the convenience of regulating air composition inside the database at the factitiousness;Moreover want to consider a safety, because when spirit's adjusting a database is a kind of database with cold closeness type and be temperature inside the database to lower, its air pressure also immediately lowers, the outside in the database two sides became air pressure bad.In addition will be round the formation pressure of two sides of protect the structures in the spirit adjust equipments movement and spirit adjust the database spirit airtightly experiment the process bad.If not pressure bad remove or control in the certain scope in time, protect a structure creation bane towards round;In addition, the spirit adjusts a database body is almost single layer building.
(Two)The air takes place system
Air occurrence system is the spirit adjusts to store medium most of equipments, is also share to invest the biggest equipments.Air inside the database regulates mainly be pass air occurrence system to complete.Currently air occurrence the system mainly includes the hydrocarbon compound combustion system, ammonia crack solution system and changes to press to adsorb the separation system of the system, film.Among them, film's separating system is more the forerunner's air occurrence system, it makes use of a hollow fiber film, to the member of different size, carry on the separation which has selectivity, separate the nitrogen and the oxygen in the compressed air, attain the purpose that the spirit adjust.Because its technique function is superior, the product quality is dependable and the price is cheap, as a result have already been choose extensively to use currently.
(Three)The air purifies system
The beard for the fruit Shu product spirit to adjust store constantly expels closing excessive CO2 inside the machine;In addition, the fruit Shu product oneself release of some volatility materials, such as the ethylene and fragrant ester, will produce harmful influence in backlog inside the database.These materials can drop with the system clearance of the air decontamination.What this kind of air decontamination system clean is again a CO2 etc. air composition, so be called machine or carbon dioxide adsorber of the air rinse.
(Four)Make a cold equipments
Spirit's adjusting to store doesn't point simplicity to regulate air, but the establishment regulate in the air under low temperature condition.So the spirit adjusts hoarding to need to make a cold equipments, be also make cold machine, include a congealed machine, compressor, evaporate a machine, reduce expenses a machine(also call an inflation valve)...etc..
(Five)Other
In addition to above-mentioned main equipments, for acquire satisfied hoarding effect, usually still need some other equipmentses, mainly include
(1)Degree of humidity regulates system to say for most fruit Shus, annoying to adjust cold storage's will appear relative humidity will lead a low circumstance, so need to add a wet machine;
(2)The air circulatory system is mainly the temperature friendly body composition which makes to store each part in the database to tend in more even consistent;
(3)O2 and CO2 analyze and record instrument hoarding to want for period usually to measurese the content of the O2 and the CO2 in the air, in order to exceed index sign scope give adjustment in time.
Two, annoy to adjust main type and condition of the market of store the database
From currently local circumstance to see, annoy to adjust to store a database to mainly have 3, they mainly express in the dissimilarity of database body, but in of the hardware equipments be then basic and consistent.In the meantime, we take 2000 catties(100 tons) of database bodies which store quantity as an example introduction the spirits of different type adjust domestics reference of hoarding price.(include the equipments of complete set and related adjust to try, training etc. expenses)
(A)Assemble a database
This is also many local related factory house recommend of.It directly the exploitation separate the hot air airtight material to carry on a construction then, so have a work period short, efficiency Gao, the quality good characteristics.But the weakness is to build price opposite and higher, it builds price about about 400,000 dollars.If the adoption forerunner's spirit adjusts an equipments, the price may be higher and attain 450,000~500,000 or so.
(Two)The soil sets up a database
The noodles divides two kinds of circumstances again here.1 kind makes use of an original cold database, add to annoy an airtight layer on this foundation, because of having already have certain foundation, so build price lower;I am another to then completely re- construct.If is the latter it builds the price ratio construction database about low 50,000 dollars or so.Front's a kind of circumstance is certainly a little bit much lower.
(Three)Big debt database
This kind of spirit's adjusting to store a database mainly is to make use of cold storage, install 1 and several spirits to adjust the database big debt in the common cold storage, make the debt body clip a set with the formation of original database body and pass a debt to outside make cold with spirit inside the debt adjust to become a spirit which is suitable for fruit Shu to store over a long period of time to adjust environment.The spirit adjusts a big debt to adopt not poisonous PVC clingfilm more and up add to establish Huo rubber a window.That database has an investment small, set up a database quickly and bear to decay with proper store object widely etc. characteristics.The price is lowest in 3, about about 200,000 dollars then.
Three, the management annoyed to adjust to store a database
Want to want to obtain satisfied hoarding effect, pure depend a hardware equipments is nothing doing.Should also strengthen before store, medium, behind the management expect.Expected before hoarding, on the other hand grasped the choice of good raw material, if the raw material has already been taken bad a perhaps mature degree very high, the hoarding methods of whatever high class all acquired satisfied hoarding effect impossibly;While storing in warehouse on the other hand, in addition to stay a necessity of well ventilated, check passage, as far as possible reduce the free space that the spirit adjusts.So, can speed spirit to adjust speed, shorten time that the spirit adjust, make the fruit Shu as early as possible get into spirit to adjust to store appearance.Therefore want to well consider a source problem;Get into spirit to adjust the agricultural product that the database stores room in the meantime, can not at most can't should store in warehouse hoarding in time over 48 hours(part of northern fruits) over 4-8 hours after requesting to adopt to accept, then can promise a fresh degree;Store process in, periodical check air inside the database, degree of humidity etc. variety, Be in time carry on regulate.This is higher to technique request and otherwise result in very great damage.Therefore suggest adopting full-automatic spirit adjusts to store a database, although the investment is some high, can lower some risks;Moreover, the spirit adjusts to store a request soon enter whole.Can't be like common fruit Shu cold database so and literally passes in and out goods and air outside the database at will gets into spirit to adjust, not only broke spirit to adjust to store appearance, but also sped spirit to adjust a wear away of door so and influence to annoy airtight.Therefore, fruit Shu database, had better a be over or the cent criticize in the short run over.
