## Abstract

The invention relates to a system of encapsulating a hygroscopic salt tablet of the type used to absorb moisture in closed environments. Said encapsulation consists of seamless cloth, usually “non-woven”, arranged so that it includes folds that minimize the air chamber between the tablet and the covering thereof. Said arrangement allows the tablet to work more effectively than other similar ones by eliminating the resistance that the air causes to the absorption of moisture. Said tablet begins to work when the ambient moisture is greater than 55%-60% and is used inside a plastic device that has slots to absorb the moist air and has a bottom container for deposit of a brine resulting from the process of absorbing moisture.

## Claims

### Claim 1

A desiccant tablet encapsulated in a non-woven cloth wherein the encapsulation is pleated in such a way that a chamber of dry air between the tablet and its encapsulation is minimized, allowing the tablet to work more effectively by eliminating the resistance to moisture absorption caused by said chamber of air.

### Claim 2 (depends on 1)

The desiccant tablet encapsulated in a cloth according claim 1, wherein the tablet weighs approximately 450 grams, which when exposed to a temperature of 25.degree. C. and a constant ambient moisture of 70% absorbs moisture for 480 hours.

### Claim 3 (depends on 1)

An encapsulation process for making the desiccant tablet encapsulated in a non-woven cloth according to claim 1, comprising cutting the cloth into an octagonal shape, placing it beneath the tablet, then pushing the tablet and its encapsulation of pleated cloth downwards, and sealing a top portion using an arm that closes the encapsulation.

### Claim 4 (depends on 3)

The encapsulation process according to claim 3, wherein the tablet weighs approximately 450 grams, which when exposed to a temperature of 25.degree. C. and a constant ambient moisture of 70% absorb moisture for 480 hours.
