Listed desiccant industry enterprise( Intentions to make good desiccant)

Jujube has high sugar content, easy to absorb moisture and be oxidized, so does the vitamin C, in the period of jujube being stocked, except the fermentation and metamorphism caused by high humidity, it's also very easy to breed pest like rice moth, and when carbon dioxide content higher than 5%, it will accelerate jujube to softening and browning, single oxygen absorber will result in anaerobic respiration, double suction oxygen absorber can absorb both oxygen and carbon dioxide in the packaging, fundamentally solve the problem on oxidize and browning.
Besides, for the coffee products, carbon dioxide will have bad effects on sense and appearance, using double suction oxygen absorber will be a good solution to this problem.

Step one: Calculate the dosage

In order to choose the right size of Oxygen Absorber, it is necessary to calculate two datas (1) the volume of oxygen in the food package (2) the amount of oxygen permeable into the food package during the shelf life. Finally, according to the amount of oxygen absorption of Oxygen Absorber, we can choose the right size.

Notice:
1.The proportion in the formula refers to the relative density of the food (g/cm3). The volume of space occupied by the packaged food can be calculated by the weight (g)/specific gravity of the food.
2.2. Formula 0.21, refers to the proportion of oxygen content in the air is 20.947%, equivalent to about 0.21.
3. Increase in water (ml) refers to the use of drainage method to measure the volume of unsealed packaging.

Notice:
1.The oxygen permeation rate of the package material in the formula (ml/m2.24h.25 degrees C) can obtain the oxygen permeation rate data of the package material from the supplier of the selected package material.
2.The packaging surface area (m2) in the formula can be calculated by expanding the packaging measurement to obtain data.According to the above formula calculated (1) the volume of oxygen in the food packaging (2) the sum of the oxygen volume permeated into the food packaging during the shelf life, that is the total amount of oxygen to be absorbed, and then according to this data to select the right size of Oxygen Absorber (please feel free to contact our customer service regarding the dosage, the model numbers will not be the same from different manufacturers).

Step two: Choose a suitable food packaging container/material

Shaped packaging: plastic cans, glass cans, tin cans, etc

Non-shaped packaging: non-stereotyped food packaging should choose oxygen permeability of 20ml/m24h.25c or less composite packaging materials, such as KOP/CPP, NY/PE, KNY/PE, KPET/PE, PET/AL/PE, etc., do not use high permeability of packaging materials, such as: OPP/CPP, PP or PE membrane bags.

Step three: put the packets into the food container by manually or automatically, then seal the container well.

Manually: No need to invest automatic dispenser, suitable for purely artificial packaging of food manufacturers or inconvenient machine food delivery.

Automatically:Suitable for fully automatic or semi-automatic food production enterprises, saving labor costs, more hygienic. Stable cooperation with customers, Chunwang can provide automatic dispenser, can inquire about customer service staff.

Notice:
1) Put the food (items) together with oxygen absorber in a container with low oxygen permeability (20ml/㎡.25℃.24h/atm), like KOP/PE,KPET/PE bag or Plastic cans, glass cans and tin cans.
2)The sealing container, the packing material need to be vacuum seal, avoiding the air to enter.
3)After bag opened, better use up within 1-2 hrs and seal the container. The left packets should be reseal in vacuum condition.
4)DO NOT MICROWAVE,DO NOT EAT.Not available for foods with high Aw.(>0.85).
5)The suitable temperature of operation is generally 5-40 ℃; below 5 ℃, oxygen absorbing effect is decreased.
6)During the reaction, packet will release a small amount of heat, this is normal and safe.

Chunwang's formula, the main ingredients are reduced iron powder, activated carbon, diatom soil, zircon, sodium chloride, water. Before oxygen absorption is black with gray particle mixture, after oxygen absorption it becomes brown. The oxygen absorption is greater than the national standard "3 times standard oxygen absorption."
