How to determine the amount of desiccant, what is the calculation?

Release date:2018-01-22 Author: Click:

The amount of desiccant used depends on a number of factors: the size of the dry space, the properties of the packaging material, the storage environment for the packaged product, the atmospheric conditions of the seal, the shelf life of the packaged product, the degree of sealing of the package, and the like. Therefore, when designing desiccant dosage for customers, it is necessary to know the above information before making the best reply.




Desiccant dosage calculation formula and parameters


n = 1 / a * (V * b + m * c + A * e * WDD * t)


n: Desiccant unit number required


a: target humidity conditions, a unit of desiccant can absorb moisture (g)


V: Inner volume of package (m3 m3)


b: Air moisture content in initial packaging at temperature and humidity (g / m3 g / m3)


m: the weight of the package containing water packaging materials (kg kg)


c: Moisture content of aqueous packaging materials (g / kg g / kg)


A: Surface area of the barrier package (m2 m2)


e: Correction factor at target humidity


WDD: Water vapor transmission rate of barrier package (g / m2 · day g / m2 · d)


t: days of storage and transportation (day d)
