Column desiccant product introduction
Column desiccants are generally commonly used at home and abroad as packaging materials, mainly divided into domestic ventilation paper, filter paper desiccant, non-woven desiccant, composite paper column desiccant, and textured paper Desiccant and Tyvek desiccant from DuPont Company of the United States.
Filter paper can be used for small-sized silica gel column desiccant packaging, which is used to pack montmorillonite powder that is not strong enough and prone to leakage, and has good air permeability.
Composite paper has poor air permeability, resulting in slow moisture absorption, and is generally not suitable for moisture-proof packaging of electronic products. Non-woven fabrics have a certain strength and excellent air permeability, but are prone to leakage when used for packaging montmorillonite. powder.
Product Introduction
Using column desiccant can extend the storage time of tea to about one year. The type of desiccant selected depends on the type of tea and the convenience of obtaining materials. To store green tea, block non-deliquesced calcium chloride desiccant can be used to store black tea and scented tea. Column desiccant charcoal can be used if conditions permit, and color-changing column desiccant can also be used.
When using calcium chloride column desiccant to preserve tea, you can first wrap the loose tea in thin kraft paper (bundle it tightly in packages of several to half a kilogram, and arrange them in layers in a dry, odorless and intact jar. Or around a small-mouthed iron can that is rust-free and odorless, put one or several bags of unweathered calcium chloride between the jar and the jar, and put a few small bags of tea leaves on top, then use kraft paper or cotton pads to block the mouth of the jar or jar, and then cover it tightly. Cover and store in a dry place. Generally change the desiccant once a month. As long as the desiccant is replaced on time, the tea will not absorb moisture and deteriorate. The charcoal tea storage method is similar to the calcium chloride method and will not be described again.
