Abstract
A method for automatic measurement and control in curd making process is provided wherein an electrical current is supplied to an electrical conductor thermally contactable with milk stored in a curd tank so as to be heated to result in sufficiently higher temperature of the said conductor than the surrounding milk, temperatures or electrical resistances of the electrical conductor are measured in relation to time lapse, an elapsed time starting from the commencement of curdling is measured on the basis of a change in temperature or electrical resistance of the electrical conductor, and the elapsed time is compared with a predetermined curdling progress time ranging from the commencement of curdling to curd cutting so as to automatically judge a curd cutting timing.
