Desiccants
1.Are there any ways to recycle desiccant that had already used?
If the desiccant still available, it can be used in the dryness for saving domestic food and shoes, etc.
RAYM is a particle-like substance before absorbing moisture, while it turns into powder after reacting. So judging whether it is still effective, you just need to see the desiccant bagged whether has particles.
However, because of silica gel and clay don’t change their shapes in any circumstances, we can't confirm the residual capacity by the state of the contents
Towards color-variable silica gel mixed with blue gel, we judging it according to its surface color. Its color would gradually turn into pink with the increasing of moisture adsorption. Recently, people don’t advocate using this kind of desiccant mixed cobalt dichloride concerning the problem of environment.

2．Ways of dispose desiccants
At home, it can be abandoned as non-burning garbage.
Due to the material of making RAYM is quicklime, and it would possibly have exothermic reaction instantly when meets water, it can’t throw over wishy-washy place.

3．If eat the lime desiccant by mistake, how to deal with?
calcium oxide is the element of quicklime, when contacts with water they get exothermic reaction. If you have any sign of be burned, please turn to the doctor. If the substance you ate is hydrated lime, don’t worry, rinse your mouth it will be OK. Hydrated lime has no toxin, can be apply to food additives. But its aqueous solution contains strong base, which may stimulate mucosa, so please drink much water or milk before you go to the hospital.
4．If you eat silica gel or clay desiccant by mistake, how to deal with?
The chemical property of silica gel and clay is steady, so they can’t be assimilated. If you happen to eat, please drink a lot of water 、milk or tea etc after you hydrated mouth. If enter eyes imprudently, please don't rub and wipe, wash with the running water immediately.
5If you boiled the food with desiccant and ate it, How to deal with?
Please take it easy. Desiccants are non-toxin, so even they Oozed out of the pouch and flew into the pan, they have no influence to human body. So don’t need special treatment. If you really very anxious about it, you can consult the doctor.
6．The desiccant expands very big in the food, why?
The expanding desiccant is the lime desiccant, whose main element is quicklime (CaO2). After it absorbed moisture, it turned into hydrated lime, Whose form changed from particles to power and volume increases by 2-2.5 times.
So while designing the desiccant pouch, our company has already considered the problem of its inflation. We strengthen the sack size, which effectively prevent the happening of burst sack.
*Equation : CaO + H2O → Ca（OH）2
7．How to distinguish desiccant from OxymoveTM?
The principle of desiccants of keeping food from dampness is by absorbing vapor inside the packing container that kept a low humidity.
While OxymoveTM is by drawing on oxygen, which effectively prevent food from oxidation, changing color and mold.
You can discriminate their usages by foods’ property and conserving aim.
8．The category and features of desiccant
Classified into 2 kinds------- Physical desiccant and chemical desiccant.
The former (RAYM) absorbing water by generating a chemical reaction with water.
The physical characteristics of the later (UNIT PAK clay and silica gel) is steadiness, it absorbs vapor by pores.
9．Can the desiccant be re-utilized?
In the course of RAYM desiccant absorbing
Moisture, it turned from quicklime to hydrated lime, whose physical characteristics had changed. So it can’t be re-utilized.
Whereas, Physical desiccant (silica gel and clay) don’t arises any diversification, which can be recycled by heating. Moreover, because the out packaging material is PE film or non-woven cloth, it should be heated under relatively low temperature (below 100.c) for long time.

10．The element of lime desiccant is quicklime, which can generate heat sharply when it contacts with water, towards this which countermeasures producer taken?
In order to guarantee the security, our company stipulates that the packaging materials must accord with the following standards.
●Intensive standard: Prevent breaking bag caused by external forces, etc.
● Size standard: Prevent the broken bag arising from absorbing moisture and inflating.
● Waterproof standard (use waterproof paper): Prevent raw materials from keeping in touch with water.
●Weight criterion (wrapper’s standard and material): Prevent breaking bag caused by external forces, etc.
●Benchmark: It is obligated to arise consumer's attention.
NSKK Intensive standard Examined items ( the follows Omitted )
11．What are the differences between Type A silica gel and Model B?
There are two kinds of silica gel who have strong ability of absorbing moisture, one is type A silica gel as long as put it under normal scope of low- humidity circumstance, which mainly apply to keep food and metal dry etc. The other one---- type B is just on the contrary, it adsorbs a large amount of moisture in high humidity and discharges gradually in low relative humidity. Type B mainly is used to control the ambient humidity.
Generally speaking, silica gel desiccant is refer to type A.
The regulation about silica gel capacity refers to JIS (Japanese industrial standard).
（Details omitted）
12．The silica gel and clay equally with physical characteristic of absorption, are there any differences between them?
Because both of them absorb vapor in the air through their pores, we call them physical desiccants. Silica gel is a kind of pore-like material, which is made by a chemical disposal----- through silica sand lying In the soil to the high purity silicon dioxide.
UNIT PAK is a special substance with pores, whose soil compositions are very active. And among the whole physical desiccants, the clay one is quite famous..
13．After the bundle of desiccants tore apart, How do you maintain the remnants?
If you put the remnants like they are, they will constantly absorbing vapor in the air, which will decline desiccant’s performance. So, you should keep them in the same bag and tie it tight with a elastic band, then put them in a relative shady and cool place.
14．Which is better between desiccant and oxygen absorber in the function of preventing metal from get rusty?
The forming reason of the rust (oxide) is mainly the existence of oxygen and water (vapor), so long as remove one of them, it can play a preventing role.
If you choose oxygen absorber, you need packaging materials with high barrier. If the bag is sealed not very well or exist holes, oxygen absorber will invalid completely. So you must very careful while using it. In addition, Before using it, you must do some experiments for confirming, because different kinds of metal have different influences affected by oxygen absorber, which may change the color of metal surface. You’d better use well-qualified waterproof packaging materials. Comparing to oxygen absorber, desiccant has the following advantages: 1, it is much economical; 2, It has better security performance, Even it happened these incidents aforementioned, It wouldn’t lose the desiccant’s capacity thoroughly. Well, no one is willing to see any problem. If you are still anxious about it, you can add a little amount.
15．Which type of desiccants is suitable for prevent metal from get rusty?
American MIL (American Martial Specification) regulated that we should use non-deliquescent salinities. For instance, the container apply to deliquescent salinities, which including series of calcium chloride, contacting with metals may possibly accelerate metallic corruption. So it can’t apply to store metals.
The raw material of silica gel is acid, even separated by packaging materials; it is inappropriate keeping with metalwork for a long time.
The series of clay desiccant including UNIT PAK are belonging to non- deliquescent desiccants, whose PH index presents neutrality. Even they keep in touch with metals, the possibility of getting rusty is very low, so , you can use them safely.

oxygen absorber (OxymoveTM)
1． Does the oxygen absorber, which had put into food, can recycle?
Once the oxygen absorber used, it would lost its function, so can’t be re-used.
2． How to dispose oxygen absorber?
At home, you can discard it as non- conflagrating garbage (organic oxygen absorber can be burnt, but it is difficult to distinguish it from iron series).
If it is widely used in industry, please deal with it as industrial castoff.
3． If ate oxygen absorber by mistake, how to deal with this kind of situation?
No matter what ferrous series or non-ferrous series oxygen absorber, they will be eliminated naturally even in the human body. So don’t worry, wash your mouth and drink some water, milk or tea etc. If it always keeps in your mind, you can go to see the doctor.
4． 5．
When you take out of the oxygen absorber sealed in the food package, you may find it heats, why?
The oxygen absorber got the three elements-------organics or the iron and oxygen in the wrapping bag to have the chemical reaction, which also gives out heat at the same time. If it still has deoxydation capability, it continues progressing reaction and giving out of heat, even if it has already put out of package. Well, don’t worry, it’s safety and can’t give rise to any fire, it wouldn’t cause these situation such as sharp heat or scald.
6． Whether the oxygen absorber can be put together with food heating in the microwave oven?
After heating, probably it can be broken or build a fire. So it must take out in advance, then heat.
7． What are the classifications and characteristics of Oxymove TM?
According to different packaging materials, oxygen absorber sorts into 2 kinds: one is used for proof oil and water; the other is towards common food. Under the following two circumstances, please use oil-proof and waterproof packaging materials: 1. the goods is greasy and watery.2: the goods will contact with oxygen absorber directly. If the goods containing little water or oil and don’t contact with oxygen absorber directly, please use common packaging materials. For the sake of caution, please do some experiments in advance to confirm the result.
8． If you expect to apply oxygen absorber to the new products, how to choose the oxygen absorber’s type and size?
Choosing suitable type according to the goods activity of water and the time what encapsulating procedure need. However, different individuals have different varieties. The approximate standards are as follows:
Specifications (atmosphere amount or oxygen amount), select a larger specification than the volume of air that be packed together with the packed object. Two kinds of ways to denote the specifications of oxygen absorber: atmosphere volume and oxygen volume.
Be sure to notice, their relation is as follows:
atmosphere volume÷5=oxygen volume
oxygen volume×5=atmosphere volume
10． How to prevent the outer pack from shrinking?
If oxygen absorber is used, probably, it would absorb oxygen in the packed bag, so the volume will be reduced, this is so called the phenomenon of out pack’s shrinking. The way to prevent this is as follows:
1）Using together with inactive gas
In order to prevent food oxidation, you can use inactive gas such as nitrogen to replace the oxygen in the package.
Of cause, it is impossible to remove all the oxygen, you know, the oxygen can infiltrate in. But if you want to preserve goods for a long time, the way is the best choice.
Don’t choose oxygen absorber with insufficient capacity to prevent the so-called pack’s shrinking, because remaining oxygen and oxygen infiltrating can make the goods go bad or degradation.
2）（Fresh Care TM）Using Fresh Care TM
If you utilize Fresh Care TM, this phenomenon will not take place.
11． Whether the oxygen absorber has a function of preventing food from fermentation?
It can’t restrain propagation of anaerobe that caused by fermented fermentation.
Fresh Care TM
1． How to distinguish Fresh Care TM and Oxymove TM？
（1）Fresh Care TM is a kind of special pouch full of volatile alcohol gas, which prevents mold by volatilization of alcohol gas.
Oxymove TM prevents oxidizing, changing color and moldy of food through absorbing the oxygen.
Both of them can prevent going moldy, but yeast can multiply regardless of the condition whether it contains oxygen.
（2）Fresh Care TM may uses the packaging materials with non-barrier with the reference to OPP/CPP etc, whose prices are relatively cheaper. However, the prices of Oxymove TM are relatively higher, they must use KOP or EVOH etc.
（3）Fresh Care TM has an effect of avoiding water’s evaporation, keeping its fresh taste and Prevent hardening.（depend on different foods and conditions）
Nevertheless, sometimes Oxymove TM absorb the water from food, that would make the food harden.
（4）After tearing the Fresh Care TM’s package, you can smell the odor of alcohol. When put the individual into food, you can hardly smell anything. Nevertheless, Oxymove TM has no odor.
（5）Fresh Care TM can’t preserve for a long time, differs to the food itself, but 2 months is the longest. However, Oxymove TM can preserve longer than Fresh Care TM.
2．Please notified the amount of Fresh Care TM
（1）Mensurate the activity of water (AW)
（2）Weight food
（3）Calculate the essential weight of Fresh Care TM
For example, there are 300g food with AW 0.85
According to the table below, we got to know 100g food with AW 0.85, should use 1g Fresh Care TM.
Fresh Care TM ‘s necessary amount = 100gFood’s necessary amount×its weight÷100
1g×300g÷100 = 3.0g
The result is to choose 3.0g Fresh Care TM .
packaging materials
Q．1Which kind of packaging materials is suitable for food when choose Oxymove TM ?
Please choose the following packaging materials with low air permeability.
①films coated with K layer
②Films coated with AL
③ Films coated with AL film
④ Coated with specialize films of low oxygen permeability such as EVOH etc.
In view of protecting environment, nowadays, people gradually use EVOH instead of using K coating.
The followings are suitable for the packaging materials of Oxymove TM
﹤EVOH/PE﹥、﹤KON/PE﹥、﹤KOP/CP﹥、﹤KPET/PE﹥、﹤PE/AL/PE﹥
Examples which are unsuitable for the packaging materials of OxymoveTM
﹤OP/CP﹥、﹤OP/PE﹥、﹤ON/PE﹥、﹤glass paper/PE﹥、﹤PET/PE﹥、 partial-coated bag、PE bag、 Non-hot- sealing bag.
Even it is metal can, it also should acknowledge that it had sealed.
If packaging materials contain holes or are sealed not very well , Oxymove TM would has no validation, so please pay attention to the form of packing and carrying method.
Examples that is unsuitable for the packaging materials of Fresh CareTM.
﹤ON/PE﹥、﹤PET/PE﹥、CPP monomer、PE monomer
When put the watery food etc. into an sealed package, the inside of packaging materials will be covered with dew. That is because the vapor food produced making the inside humidity exceed 100%. While this kind of water contacts with food and gathered on the bottom of the package, the packed food will go bad. Using desiccants can settle this problem. Of course it may change according to the foods’ variety. Besides, The vapor can go out from incomplete sealed wrapper or holey film, thus dew-covering arising can be prevented efficiently.
