Description
Technical field
The invention relates to ethylene adsorption gas and keep the composition of the freshness of gardening product and food and relevant freezer deodorant and manufacturing process.In more detail mixture cooperation, shaping, the drying of the red soil of various forms and activated carbon, anoxic is calcined and is immersed in and removes the impurity after washing in the hydrochloric acid solution under 950 ℃ of conditions, injects 15～20% frerrous chloride isoreactivity slaines in the composition of washing.The product of Zhi Zaoing has very excellent in performance to removing the foul gas in the freezer and the gas of absorption corrosion gardening product like this, and has increased adsorbance it can be used for a long time.Simultaneously in the application of field of food because of having the advantages that to keep freshness, so the invention relates to the stench that produces on removal freezer, the gardening product treatment facility and invention to the composition of the very effective deodorization medicament that purifies air and relevant manufacturing process.
Background technology
For the freshness that keeps gardening product and food uses the ethene remover to be because the more and more stronger result of desire more fresh, the better product of taste is sought in the raising of consumer's the consumption consciousness recently, therefore be not only large-scale circulation company, agricultural product whole seller at present, the epoch of fresh produce are also sold in the supermarket.Again the producer and the producing region between keen competition caused the long distanceization in consumption place and the competition of quality.Here require because long preservation is adjusted outbound and keep the highly preservation technology of freshness in the process of circulation.Because the gardening product major part all contains very high moisture content, and perishable, thereby occurred after the harvesting reducing the situation that freshness brings the commodity performance obviously to descend or completely lose because of inappropriate storage and circulation.After the harvesting store and the process of circulation in influence the factor of crops freshness many, but the tissue of accelerating because of physiological reason (ethylene gas) aging be the sale time limit of shortening product, the major reason of reduction product quality.Can remove activated carbon, the potassium permanganate (KMnO of ethene
4) wait in the material, activated carbon has the removal efficient of pair low-concentration ethane low, and the ethene that not only is adsorbed on the activated carbon may be emitted, and the too moist shortcoming that can reduce its removal ability.Potassium permanganate effect on the ability that continues removal ethene is very good, but because of containing the heavy metal of strong toxicity, because of carelessness at remover with after agricultural product contact, because disaster can take place strong oxidizing property, and can not utilize again after using, so need when handling to note especially.Therefore the present invention is the problem that exists when solving above-mentioned removal ethene, and keeps the freshness of gardening product and the freshness of food to develop.
" deodorant " is meant to removing Korea S's atmospheric environment and saves hydrogen sulfide, methyl mercaptan, ammonia, amino class and other gaseous matters excitatory that is defined as stench in the method from damage in the present invention, and causing unplessantness displeasure after the stimulation sense of smell and detesting the smell of feeling is the material that purpose is used.Stench is caused by the mixing of several compounds that generally these materials not only cause offending taste, and human body is also had bad influence.
Popular deodour method has the method for using stabilized chlorine dioxide at present, utilize additive and deodorant that the masking agent method that strong fragrance is covered odorant is sprayed in the deodorization source, nertralizer by certain concentration in big gas jet and the method for taste composition, use activated carbon, charcoal, the molecular sieve of silica-gel desiccant and zeolite etc. is to methods such as deodorization source absorption.
Masking agent method in the above-mentioned deodour method is difficult to the basic effect of removing stench of expectation because of strong fragrance, and existence combines the worry that the 3rd kind of harmful material caused in the back with odorant.The method of spraying neutralization is because nertralizer band flavor itself can disappear with the concentration of object gas is irrelevant, and the additional simultaneously gas that generates is also harmful to the person.Therefore traditional deodour method of extensive use is the suction type that utilizes molecular sieve.Because molecular sieve is strong to the absorption affinity of moisture content,, when moisture content is too high, have the characteristics that absorption affinity too reduces so can reduce its freshness by dry gardening product.
On the one hand, use coconut meat, the coal class during material charings such as timber, is made activated carbon after the activate under reducing condition, and its form has granular, broken shape and Powdered etc., and pore diameter is about 1～100nm, and major part is made up of the tiny pore below the 2nm.Activated carbon is the lipophile adsorbent, and is strong to the absorption of nonpolar molecule, though specific area is without limits, and general 1000～1400m
2/ g is for more suitable.Such activated carbon has general absorption removal effect as traditional adsorbent to stench widely, is divided into alkalescence, neutrality, acid activated carbon according to the gas of adsorption treatment.Though non-polar hydrocarbon such as activated carbon Pyrogentisinic Acid, toluene have tangible adsorption effect, low-boiling compounds such as ethene, ammonia and polar molecule foul gas had the shortcoming that can not fully absorb.
Therefore recently in order to replenish the adsorption capacity of hydrophily adsorbent zeolite and lipophile adsorption activity carbon, reported much about zeolite and activated carbon and mixed the manufacturing process of the adsorbent that complex function is arranged and material that can active carbide, and the bond of zeolite and analog or silicate compound and the activated carbon manufacturing process of mixing.
Ri Ben patent for example, Japanese publication communique clear and 54-53669 number on published and added bentonite in zeolite and the activated carbon mixture and gentle method of decomposing with product is made in white sugar postforming, drying, calcining.In above-mentioned manufacturing process, used the bentonite of natural red soil class, so be mingled with impurity in the product as inorganic bonding agent.
On the flat city 4-4039 of Japanese publication communique number, published and added the method that the blast furnace ash powder is made the oil absorption water treatment agent in the zeolite, but present technique has caused the ecological safety issue of blast furnace ash, and forming property is bad, spheroidizing engineering difficulty, the problem low to the lipophile adsorptivity.
At Japanese publication communique clear and 59-69146 number on published and added the method that the shape adsorbent is filtered in the manufacturing of silicic acid chloride in the activated carbon, but present technique exists activated carbon to be stopped up pore by the silicic acid chloride again and reduces the problem of absorption property because of the molecular sieve effect.
Published the technology of in zeolite and activated carbon mixture, adding inorganic bonding agent-alkaline soil metal silicate and organic bond honey on the patent 94-18327 of Korea S.There is the calcining engineering in present technique on manufacturing process, so there is above-mentioned problem too.Simultaneously on the ability of improving energy of adsorption and specific area, there is limit.On Korean Patent 97-0031732 number about also having the calcining engineering in zeolite and lipophile, non-polar compound and the manufacturing technology that activated carbon combines, there are the problems referred to above too through calcining with after injecting metal, and owing to dust problem occurs after forming property and the wearing and tearing, so also have limit on energy of adsorption and the specific area improving.
Summary of the invention
So the present invention is in order to improve the problems referred to above, and constantly make great efforts the result that exploitation can keep gardening product and food freshness and have the deodorant of freezer deodorizing performance.Finished and injected metal ingredient after hydrophily and the activated carbon that outstanding absorption property arranged to the red soil composition that has layer structure of the very strong adsorption capacity of polar molecule with to lipophile and nonpolar molecule suitably removed foreign body in conjunction with postforming, drying, calcining and by pickling, the adsorbance of specific composition has been had the invention of the deodorant compositions of the increase of epoch-making significance and that imparts selective.The red soil (Red Mud) that has flourishing layer structure is the accessory substance that generates behind the extraction alumina from red bauxite, very active influence is arranged utilizing of expense of saving material and accessory substance aspect close environment such as effect and the economy.So the invention provides have hydrophilic and lipophile simultaneously, to the adsorption capacity of polarity and nonpolar molecule, and deodorant compositions and its manufacturing process that can keep the outstanding characterization of adsorption of having of freshness to freezer and gardening product and food.

The A freezer of not removing ethene shows that with the investigation result of the B freezer of having removed ethene in the same time period murder degree of A freezer approximately is 3 times of B freezer.And the pears of producing in same farmers' are increased to 58.2% along with spot that the variation of time occurs in freezer, and the spot that occurs in the pilot freezer of removing ethene is about 7.2%.
Example 6
Remove effect in order to examine ethene, after the Bai Taoyong PVC plastics vacuolar membrane of harvesting just packing, placed 5 days, compared the fruit hardness in the ethene removal and the district of being untreated at normal temperature.The hardness of ethene treatment region is 0.56kg, and is high more about 12% than the hardness 0.5kg that is untreated, so be the treatment effect that object has been examined development with Huang Tao.
In experiment, the yellow peach in the good garden of the length of harvesting just is divided into two groups according to the look state.Uncoloured crude fruit and painted mellow fruit were object at storage in 4 ℃ after 15 days, and normal temperature condition exposes down, gives selling term, by each phase analysis quality.
Just the immature friut and pericarp color of harvesting is deep green, but after normal temperature exposed 3 days, the leaf green minimizing had appearred in each stage, and yellow thickens, and has red phasic Chang a little.Thereupon the HUE value also from bottle-green 100.91 change to untreated 89.17 and treatment region 93.12.What can relax change in color because of our company's development product has proved its effect.But hardness does not have too big difference, and the deviation ratio of the fruit that usefulness our company development product is handled is bigger.The effect that generally speaking stores back removal ethene is apparent in view, but the result that hardness is kept effect has appearred reducing in the normal temperature exposure after 3 days.Inconsistent about the difference of the influence of pol being managed throughout the district, but acid content is kept than higher in treatment region, and the taste of fruit and quality seem fine.
Though the ethene generation rate of fruit is inconsistent, the ethylene concentration of treatment region is lower on the whole, and the respiratory rate of treatment region significantly is not inclined to.Significantly characteristics are when normal temperature exposes under untreated situation, often take place because of rotting or the rotten phenomenon that reduces commodity of pulp.Such phenomenon is rare in the ethene treatment region, can produce effect very much to keeping the fruit freshness by determination processing ethene from such phenomenon.That is, be that object carries out ethene when suppress handling with immature yellow peach, can keep very high hardness, proved that our company's product can delay the effect that pericarp variable color etc. keeps freshness.
Composition among the present invention has very flourishing tiny pore, physical absorption and chemisorbed can take place simultaneously, because adsorption capacity and removal efficient height, for organic solvent class, toxic gas (ammonia, hydrogen sulfide, trimethylamine) and very outstanding, and at freezer to the adsorption capacity that makes the aging hormone ethylene gas of plant with also very useful in the application of deodorant, freshness retention agent and air cleaning deodorization filter material.
