Title:
COAGULANT CONTROL FOR PRODUCING TOFU
Document Type and Number:
WIPO Patent Application WO/2012/032453
Kind Code:
A3
Abstract:
The invention proposes a method and apparatus for producing tofu. The apparatus comprises a first unit (100) for obtaining the electric conductivity of the water; a generator (102) for generating soymilk from soybeans and water; a first detector (104) for detecting the electric conductivity of the soymilk; a calculator (106) for calculating the amount of coagulant to be added to the soymilk, in dependence on the obtained electric conductivity of the water and the detected electric conductivity of the soymilk; and a second unit (108) for adding coagulant to the soymilk in dependence on the calculated amount. The obtained electric conductivity of the water and the detected electric conductivity of the soymilk can reflect the soymilk concentration. Thus, for each tofu-making process, the invention flexibly calculates a suitable amount of the coagulant, even if the soymilk concentration varies. The taste as well as the texture of tofu can be consistent irrespective of the soymilk concentration.
