Method for manufacturing onion pulp for paper and capsule

Abstract

A method of manufacturing onion pulp according to one embodiment of the present disclosure may include generating a ground onion product by grinding onions to remove sugar and sulfur components from the onions, mixing and stirring jelly powder and purified water at a predetermined ratio, heating a primary mixture in which the jelly powder and the purified water are mixed, stirring the primary mixture with the ground onion product, molding a final mixture, including the stirred jelly powder, purified water, and ground onion product, after placing the final mixture on a mold, and drying the molded final mixture.

What is claimed is: 
     
         1 . A method of manufacturing pulp, the method comprising: 
 grinding onions to remove sugar and sulfur components from the onions;   mixing powder including polysaccharide or protein with purified water to generate a primary mixture;   stirring the primary mixture with the ground onions;   molding a final mixture, including the stirred primary mixture and ground onions, after placing the final mixture on a mold; and   drying the molded final mixture.   
     
     
         2 . The method of  claim 1 , wherein the grinding of the onions includes: 
 primarily grinding the onions to a predetermined size to form primary ground onions; and   secondarily grinding the primarily ground onions to a smaller size than the predetermined size to form secondary ground onions.   
     
     
         3 . The method of  claim 1 , wherein in the grinding of the onions, the onions are ground variably in particle size according to a desired tensile strength of the pulp. 
     
     
         4 . The method of  claim 1 , wherein in the grinding of the onions, the onions are ground differently in particle size according to a ratio of the sugar and sulfur components to be removed. 
     
     
         5 . The method of  claim 1 , further comprising freezing and thawing the ground onions after grinding the onions. 
     
     
         6 . The method of  claim 1 , further comprising adding salt to the ground onions to facilitate removal of the sugar and sulfur components from the ground onions. 
     
     
         7 . The method of  claim 1 , further comprising heating the primary mixture for a predetermined time to restrict decomposition of starch molecules in the powder. 
     
     
         8 . The method of  claim 7 , wherein in the heating of the primary mixture, the primary mixture is heated at 100℃ for the predetermined time. 
     
     
         9 . The method of  claim 1 , wherein the powder is made of mung bean jelly powder. 
     
     
         10 . The method of  claim 1 , wherein the powder is made of acorn jelly powder. 
     
     
         11 . The method of  claim 1 , wherein the powder is made of agar jelly powder. 
     
     
         12 . The method of  claim 1 , wherein in mixing of the powder with purified water, a ratio of the powder to the purified water is 1:60. or 1:70.
