Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing floating soap that has a reduced specific gravity by incorporating air or other gases, and in particular, a continuous process for producing floating soap that uses an extruder to obtain continuous soap bars. It is related to the device.

As a known method for producing floating soap, neat soap obtained by a conventional method is passed through a closed-type heater heated by high-pressure steam under a pressure of 17.5 kg/+++" or higher. The soap is then heated to a temperature of 200 DEG C., preferably by pumping, and discharged through a sedge nozzle into a flushing chamber, with evaporation of sufficient moisture to reduce its moisture content to about 20 degrees centigrade. The soap is concentrated by a so-called 7-lash drying step, in which the soap is injected into atmospheric pressure and at the same time the temperature of the soap is reduced to a temperature corresponding to the boiling point of the soap containing this reduced moisture percentage, i.e. about 106°C. The hot molten soap Ila/l is fed to the continuous clutch 1-, and the perfume, preservatives and colorants are added to the continuous clutch 1- Robert
V. Burt, U.S. Pat. Sufficient quantities are introduced into the molten soap stream, which is then pumped into a specially designed cooling device called a Bocheetah, where it is cooled on the inner surface of a cooling jacket, rapidly scraped off by a scrunchper, and succin The paste-like sticky soap mass, which has been mixed with the uncooled soap by stirring according to A'-, and which has been cooled and stirred, is squeezed out from a hole at the end of the wringer discharge chamber connected to the bow cheater, There is a known method of producing floating soap by cutting it with a cutter and stamping it, but this method requires a flushing dryer and a bow cheetah cooling device, which increases the equipment cost and is complicated to operate. It requires a high degree of skill and experience, and is also suitable for the purpose of pumping concentrated, highly viscous, molten soap glue into a continuous clutch machine, a tater cooling device, and a squeezing discharge chamber. This manufacturing method has not been widely used to date because of the drawbacks such as the need for

Also, regarding the production of floating soap, the moisture content is 30-35-
A good manufacturing method has been disclosed for the purpose of continuously preventing floating soap with a high content of (% opening 48-2
5706).

However, floating soap, which is in demand worldwide and is known by the product name "Ai Gari", has a water content of 20%.
It's nearby.

This is because floating soap with a water content of 30-355G has excessive friction solubility during use and is easily reduced, and after production, the water evaporates to a large extent and the soap shrinks and deforms, reducing its commercial value. Indicates that the product has inferior disadvantages.

The object of the present invention is to avoid the need for a new flushing dryer, and to obtain a dryer that is conventionally used in the soap manufacturing industry, that is, a so-called 4-nd dryer or a vacuum dryer. Using solid dry soap pellets, ribbons, or flakes with a moisture content of 20 to 25 inches as the starting material, the method does not require a cooling process using a specially constructed cooling device called a tater, and can be concentrated. It also eliminates the need for a continuous clarifier and single-cheater cooler and a pump suitable for pumping the highly viscous molten soap into the squeezing discharge chamber 12;
The solid dry surface soap pellets can be mixed into 17 lakes in a mixer, conventionally used in the soap manufacturing industry, without the need for a proportional dosing metering pump to proportionally feed preservatives and colorants into a continuous clarifier. For inerigan, fragrance,
It has the advantage of being able to use a solid dry soap base as a starting material, which is obtained through a simple process of adding and mixing preservatives or colorants, and then easily producing floating soap continuously. To provide a continuous floating soap manufacturing device that makes it possible to do this.

A heat exchanger consisting of a so-called multi-tube group is connected, and then the soap, which is in a similar state to a semi-molten state, exiting the heat exchanger is stirred and mixed uniformly in order to reduce the temperature difference. A mixing and stirring chamber in which a stirring blade or a baffle plate having a mixing and stirring function that provides resistance to the flow of soap rotates is connected to the rotating shaft. The soap that has been brought to a state similar to a semi-molten state through a heat exchanger for heating and a mixing and stirring chamber for heating the passed soap passes through a connecting pipe and is heated by a rotating pre-pro ladder screw. A fixed pin with a half-moon cross section is attached to the inner wall of the cylinder, which has a shaft and four separate rotating shafts.

In the communication pipe, compressed air or other compressed gas is passed from the outside through the flow line to the flow of semi-molten soap, and the final product has a specific gravity in the range of 0.8 to 0.95. It is press-fitted at a ratio that can be obtained in the area.

On the exit side of the shearing, mixing, dispersing, and maturing cylinder, there is a bearing that supports one end of the rotating shaft, and the bearing is supported by a support member from the inner wall of the cylinder.

A stirring blade or other rotational resistor for further stirring and mixing the soap that has passed through the support member is attached to the bearing of the rotating shaft and the extension shaft on the outlet side.

Next, a squeezing chamber is connected to the tip, which is equipped with an opening member called a mouthpiece, which defines the cross-sectional shape of the pressed soap bar.

The solid soap material with a moisture content of around 20, sent from Gregrodder soap material supply Rochno 4-, is made up of a multi-tube group by a screw rotating inside the Pregrodder cylinder, and is intended for heating. While passing through the heat exchanger tube, the outside of the tube is heated with steam or other heating medium to uniformly form a semi-molten analogue 11, and then mixed and stirred, heated in such a heat exchanger, And mixing and stirring in the mixing room 1!

In the connecting line, compressed air or other compressed gas is injected from the outside via the I4 pipe into the flow of semi-molten soap passing through the connecting line. Shearing, mixing, dispersing, and maturing Inside the cylinder, the gas injected through the connecting pipe is dispersed into delicate bubbles to form a homogeneous soap mass containing gas. Soap, which has a lighter specific gravity than water, is squeezed out as a continuous rod. This continuous bar of soap was cut into billets, and then molded into a bottom mold to obtain a floating soap product.

Note that although the explanation here has been made with respect to fatty acid alkali metal salts consisting of sodium salts of fatty acids or mixtures of sodium salts of fatty acids and potassium salts of fatty acids, the present invention is applicable to solid synthetic detergents or both soap and synthetic detergents. This also applies to solid floating detergents that are mixtures of.
