Patent ID: 7640847

Claim:
A device for determining an end point of cooking of grains which comprises the following components: a ram or a plunger mounted on a housing and adapted to move linearly in said housing, a lever comprising first and second ends, the first end being connected to said ram and mounted on said housing, the second end of said lever being free, loading means for receiving a predetermined load of weights disposed at said second end, a platform at a foot of said housing on which a pair of plates are disposable, a sample of grains being disposable between said plates, said components being arranged such that addition of a predetermined load of weights on the loading means for receiving a predetermined load weights depresses said lever downwardly causing it to push said ram downwards against said pair of plates, and thereby presses the sample of grains contained therebetween, causing it to spread, so that an area to which the grains spread can be determined and measured at a regular time interval, the time at which a sudden increase or attainment of a constant value in the area of spread is observed being an indication of a cooking time of said grains.
