A sterilized effervescent tablet comprising a.

Hereinafter, the present invention will be described in more detail.

Sterilized effervescent tablet of the present invention is sodium dichloroisocyanuric acid (SDIC; Sodium Dichloroisocyanuric Acid) 30 to 60% by weight; 20 to 40% by weight of carbonate or bicarbonate; 10-20% by weight of an organic acid having 4 to 22 carbon atoms; And 2 to 10 weight percent of a polyethylene glycol binder.

Examples of the organic acid of 4 to 22 carbon atoms in the present invention are succinic acid, sulfamic acid, adipic acid, capric acid, lauric acid, formic acid, glutamic acid, glycolic acid, malic acid, maridic acid, oleic acid, sebacic acid and One or more types can be selected and used from the group which consists of these mixtures.

Examples of carbonates or bicarbonates usable in the present invention include sodium chlorite, sodium chromate, sodium citrate, sodium formate, sodium gloconate, sodium hexafluorosilicate, sodium lactate, sodium lauryl sulfate, sodium salicylate, sodium selenite, Sodium sulfate, sodium stannate, and the like, of which sodium bicarbonate is preferred.

In the present invention, the polyethylene glycol plays a role of preventing the mixture from sticking to the punch during tableting, and is included in an amount of 2 to 10% by weight based on the total composition. When tableting a mixture of sodium dichloroisocyanuric acid (SDIC), a carbonate or bicarbonate and an organic acid, the mixture is stuck to the punch of the tableting machine, which makes it difficult to perform tableting. Add glycol. In the present invention, when the blending amount of polyethylene glycol is less than 2% by weight, the mixture may stick to the punch at the time of tableting, and thus, the progress of the tableting operation is difficult. On the other hand, when the blending amount of polyethylene glycol exceeds 10% by weight, disinfection There is a disadvantage in that the compounding amount of the component is reduced so that sufficient disinfection effect can not be exerted.

In the present invention, the size of the compressed tablet tableted in the present invention can be produced in a variety of 0.5g to 300g, the dissolution time of the product is dissolved between 1 minute and 7 minutes, the hydrogen ion concentration of the dissolved product is variously adjusted from 4.5 to 7.5 Can be. These conditions can be adjusted to suit the application by adjusting the mixing ratio of each component of the foamed tablet.

Looking at the manufacturing method of the sterilized expanded tablet of the present invention, the raw materials are dried for 30 minutes to 4 hours at a temperature of 30 ~ 90 ℃. The dried product is blended, but first, 10 to 20% by weight of an organic acid having 4 to 22 carbon atoms and 20 to 40% by weight of carbonate or bicarbonate are mixed. After the two components are mixed as described above, the mixed product is mixed with 30 to 60% by weight of sodium dichloroisocyanuric acid (SDIC) and 2 to 10% by weight of polyethylene glycol within 20 minutes. When mixing, the humidity should be maintained within 50%. If the humidity exceeds 50%, the tablet may be stuck to the punch due to the hygroscopicity during the tableting, which may make tableting difficult and reduce productivity.

The mixed material is transferred through a conveyor and then compressed into tablets. The tableting process assembles the punch to the tableting machine during the first mixing step and then idles for 10 minutes. Subsequently, a raw material is thrown into a primary hopper, a partition of a hopper is opened slowly, and a raw material is put into a punch die | dye, and a work is performed. It is preferable to make the punching strength into 30-60 kgf / cm <2> or more in working conditions.

Tablets should be packaged with care for humidity control. Humidity control and drying management of raw materials is important for manufactured tablets, humidity of tablets is controlled within 50%, and drying management of raw materials is controlled within 5%.

Hereinafter, exemplary embodiments of the present invention will be described with reference to examples, but these are only for the purpose of description and are not intended to limit the protection scope of the present invention.
