JP2002255546A - Method for producing massive fired calcium - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make a fired calcium into grain-like or tablet-like form (collec tively referred to as massive in this invention) to facilitate use for a water cleaner or for cleaning water in a bathtub. SOLUTION: A hardening agent and water are added to powdery fired calcium, the mixture is stirred and formed into grains of around 10 to 50 mm diameter, or subjected to tablet forming. A foaming agent may further be added.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for pulverizing calcined calcium and then granulating or compressing the calcined calcium into a desired size.

[0002]

2. Description of the Related Art Calcined calcium is obtained by calcining natural shells, is approved for use as an additive in foods under the Food Sanitation Law, and has an antibacterial property, especially a bactericidal effect against bacteria such as O-157. Has been found to be excellent.

[0003]

The calcined calcium is inconvenient to use because it has horns if it is simply crushed. In addition, powdery substances easily flow out together with water and are difficult to enter into a water purifier, and it is difficult to introduce an appropriate amount.

[0004] The present invention solves the above-mentioned conventional disadvantages, and uses calcined calcium in the form of granules or tablets (collectively referred to as lumps in the present invention) for purifying water or bath water. The purpose is to make it easier.

[0005]

In order to achieve the above object, a first aspect of the present invention is to add a hardening agent and water to powdered calcined calcium, stir the mixture, and then form the mixture into particles having a diameter of about 10 to 50 mm. It is characterized by doing. The invention according to claim 2 is characterized in that a hardening agent and water are added to powdered calcined calcium, and the mixture is stirred and then tableted. A foaming agent may be further added to the powdered calcined calcium of the first or second aspect.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The manufacturing method of the present invention will be described below. First, the shells are fired. The type of shell to be used is not particularly limited, but a hook clam is used because of its strong antibacterial action. The calcined shell is pulverized to obtain powdered calcined calcium. The pulverization is performed using a known crusher or ball mill to 600 to 100 mesh.

Next, this powdered calcined calcium 85 to 85
15 to 5 g of a curing agent is added to 95 g, and the whole is 100 g.
And further add 15-30 cc of water and stir. The curing agent shall be approved to be added to foods such as starch and cellulose.

[0008] Thereafter, the clay-like calcined calcium is put into a mold, placed in a container having a hole at the tip, extruded from the hole, and then cut to a predetermined size, or tableted. It is formed into a predetermined shape by slipping or the like.

[0009] When the bulk calcined calcium obtained as described above is added in the same form as activated carbon to, for example, a filter of a water purifier, water comes into contact with the massive calcined calcium and is sterilized, thereby improving the water purification effect. Furthermore, even when the bulk calcined calcium is dissolved in water, it is recognized as a food additive, has no harm to the human body, and has the effect of changing the water into a calcium-rich water. Alternatively, if the mass of calcined calcium is incorporated in the portion where the bath water circulates, the bath water is sterilized and sanitary.

Next, another embodiment will be described. The difference from the above embodiment is that a foaming agent is added in an amount of about 5 to 10% by weight at the stage of making clay-like calcined calcium. As the foaming agent, one obtained by adding an organic acid such as citric acid to a carbonate such as potassium carbonate and / or a bicarbonate such as sodium bicarbonate is used. As described above, the powdered calcined calcium spreads throughout the water due to the diffusing force of the foaming agent and dissolves well even without stirring when the foaming agent is added, and thus it is most suitable for disinfecting bath water.

[0011]

In summary, according to the present invention, a hardening agent and water are added to powdered calcined calcium, followed by stirring, followed by molding into granules having a diameter of about 10 to 50 mm or tableting. It is large in size and suitable as a disinfectant for water purifiers and bath water. Further, by adding a foaming agent, it becomes easy to diffuse into water.
