Abstract
The utility model relates to a nontoxic air conditioning agent used for storing industrial and agricultural products. The surface of an integral air conditioning tablet formed by iron oxygen scavenger and a polythene porous film is provided with a water leaking recess, the porous film can be used for causing reaction to achieve proper speed via the size and the number of small holes and storing and leaking water for initiating reaction later in order to keep definite reaction quantity and enhance oxygen removing capability which can reach to the level of 158-176 ml/g, and the utility model is mainly used for killing insects or keeping quality or preserving refreshment in a closed vessel (bag) via air conditioning. A tower for the deodorization and acid neutralization of oil and fat comprises a plate type tower, and the upper part of the plate type tower is provided with a packed tower communicated with an inner cavity of the plate type tower. Since the plate type tower and the packed tower are made into an integral structure, the utility model has the advantage of high efficiency via using the packed tower for eliminating a low boiling point assembly. The time of the deodorization and acid neutralization of oil and fat is shortened, the loss of nutrient ingredients contained in the oil and fat is reduced, and energy is saved. Simultaneously, the utility model has the advantages of compact structure and small ground occupation.
Description
The utility model relates to deinsectization, particularly relates to industrial and agricultural products: the deinsectization of grain, seed, wool fabric, Chinese medicinal materials, the guaranteeing the quality and food fresh keeping of precision component, antique, painting and calligraphy.
Existing storage period deinsectization method will be used the agricultural chemicals fumigation, and vacuum is filled nitrogen or the deinsectization of carbonating controlled atmosphere; And food fresh keeping is also used vacuum, nitrogen-filled packaging and is infiltrated methods such as additive is anticorrosion.The agricultural chemicals fumigation is used aluminium phosphide, trichloronitromethane always, and they all are highly toxic substances, is in peril of one's life during use, and more or less residual hazard is arranged, and also causes the place to pollute, and treatment effect often has only 30%; Vacuum and fill nitrogen and need main equipment, vacuum method is fresh-keeping because of not divisible food includes gas, practice confirms poor effect, and additive enter human body neither be reliable fully, it has changed the original local flavor of food.This wherein the controlled atmosphere method all be the quantitative extraction and the injection of gas.
Imagining another kind of air conditioning technology is the effect realization gas regulation of utilizing the degasification of toxicological harmless chemical substance or generating gas, it is put into the confined chamber that fills handled thing, just can produce suitable controlled atmosphere atmosphere, and reach deinsectization, guarantee the quality, fresh-keeping purpose, but the prerequisite performance of the oxygen scavenger that is used for air conditioning technology is: toxicological harmless can keep definite reaction equivalent and efficient.And existing oxygen scavenger is an amorphous substance, is wrapped in air-permeable paper, moulds in the bag, and the deoxygenation of can only not fixing a number is difficult to realize that the quantitative adjusting of gas is with efficient.At present, oxygen scavenger has with metallic iron, and V-Brite B, ferrous sulfate are the powdery product of major ingredient, also having with the aluminum oxide according to the data introduction is the oxygen uptake resin of composition, and iron to be oxygen scavenger have safe and harmless advantage easily is that people accept, but iron is in the oxygen scavenger production, after adding water during prescription, immediately with air in oxygen reaction, from the batching mixing to the secondary package process, make the reductibility partial loss, waste, reduced the deoxygenation ability, lost the reaction equivalent of determining.
The purpose of this utility model is to provide the air conditioning agent of a kind of oxygen scavenger and porous insert film integral structure, its porous insert film can be controlled the deoxygenation speed of response, can realize nontoxic, quantitative, efficient adjusting at later stage infiltration and water storage again to gas in the confined chamber, be used for deinsectization, guarantee the quality, fresh-keeping.
According to dry metallic iron in air not with the principle of oxygen reaction, imagination make a kind of can the pilot-gas exchange, again can just infiltration before package encapsulation, the structure of water storage initiation reaction to avoid the reductibility premature loss, keeps the reaction equivalent, raising deoxygenation ability.
The technical solution of the utility model is as follows:
The utility model is that iron is the controlled atmosphere tablet of the integral structure of oxygen scavenger and its outside polyethylene porous insert film composition, and profile is garden shape or square or its distortion.
Its iron is that oxygen scavenger is contained by the porous insert film, seemingly is the garden sheet in the porous insert film, and quality is loose, and bigger specific surface area is arranged, and is beneficial to the carrying out that reacts.
In its porous insert film cancellated micropore is arranged, entire exterior surface has dense micro-hole layer, and on the make how many CONTROL PROCESS just can control its pore size and hole count, just can reach suitable speed of response.Permeable and the water storage of the micropore of its porous insert film is convenient infiltration, is shaped on the infiltration depression on its porous insert film.
When the utility model is made, iron is that oxygen scavenger is faric in the polyethylene film material, can make different shapes, the preparation entire making process of size is anhydrous, just infiltrate a certain amount of water before the package encapsulation, the initiation reaction of also can seeping water in use, so just having kept iron preferably is the reaction equivalent of oxygen scavenger, makes it to be used for controlled atmosphere.
The utility model advantage is as follows:
1. the utility model has higher deoxygenation ability, and it is 158~176ml/g that unit removes the O2 ability.
2. the utility model has kept the reaction equivalent of degasifier more definitely, make it the suitable gas component of real controlled atmosphere, through practicality, during the seed deinsectization, the suitable controlled atmosphere atmosphere of determining can 100% kill off the insect pests adult, pupa, larva, ovum can be preserved the life of seed again.
3. all manufactured materials toxicological harmlesss are safe in utilization, do not endanger people and animals, and the protection environment uses the back residue easily to degrade, and is real green preparation.
4. the utility model structure also is suitable for the controlled atmosphere purposes of multiple gases component, and fresh-keeping as numerous food practically confirms that effect is better than other method, and is simple to operate, and economy does not change original packaged form.
5. do not need expensive main equipment, can enter enterprise and family.
Description of drawings:
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model vertical view.
Iron is that oxygen scavenger 1 and outside poly-second polyene sintered porous bodies film 2 are made incorporate controlled atmosphere tablet among Fig. 1, Fig. 2, iron is that oxygen scavenger 1 seemingly is the garden sheet in porous film body 2, quality is loose, bigger specific surface area is arranged, help the carrying out that react, cancellated micropore is arranged in the porous insert film 2, infiltration depression 3 is arranged above it, the entire exterior surface of porous insert film 2 has fine and close microporous layers 4, and how many may command gas flows of the size in its hole and quantity make chemical reaction reach suitable speed.
Claims (2)
1. a toxicological harmless air conditioning agent is characterized in that by iron be the controlled atmosphere tablet that oxygen scavenger 1 and its outside porous film body 2 are formed integral structure, and netted microvoid structure is arranged in the porous insert film 2, is provided with infiltration depression 3 above, and entire exterior surface has dense micro-hole layer 4.
