Solid Defoaming Agent

Abstract

The present invention provides a method for producing a solid defoaming/antifoaming agent comprising the following steps: providing an alkaline solution; adding an oil to the above alkaline solution to produce a saponification reaction; adding a liquid antifoaming agent; and putting aside the mixture containing the above alkaline solution, the oil and the liquid antifoaming agent to form the solid antifoaming agent. The ingredients of the solid antifoaming agent according to the present invention include 5˜40 weight percent vegetable oil, a 20˜40 weight percent sodium hydroxide solution and a 30˜60 weight percent liquid antifoaming agent.

What is claimed is: 
     
         1 . A solid antifoaming agent having the following compositions:
 5˜40 weight percent vegetable oil;   20˜40 weight percent sodium hydroxide solution; and   30˜60 weight percent liquid antifoaming agent.   
     
     
         2 . The solid antifoaming agent of  claim 1 , wherein said vegetable oil includes 10˜20 weight percent coconut oil and 5˜10 weight percent palm oil. 
     
     
         3 . The solid antifoaming agent of  claim 1 , wherein said liquid antifoaming agent includes a silicone antifoaming agent. 
     
     
         4 . The solid antifoaming agent of  claim 1  further comprising 2˜5 weight percent agar. 
     
     
         5 . The solid antifoaming agent of  claim 4 , wherein said agar includes a carrageenan. 
     
     
         6 . The solid antifoaming agent of  claim 1  further comprising 1˜3 weight percent powdered activated carbon. 
     
     
         7 . The solid antifoaming agent of  claim 1 , wherein said compositions include 20 weight percent vegetable oil, 30 weight percent sodium hydroxide solution and 45 weight percent liquid antifoaming agent.
