A recording mixer for 5- or 10-g. flour samples is described. It has a sensitive electronic torque-recording system. The sample bowl is fixed rigidly, and damping of its suspension is not required. The path traced by the mixing pins is constant in relation to the pins in the bowl. Calibration of the apparatus is checked by gravity weights and is changed by simple adjustments. High-frequency torque fluctuations can be recorded to show individual shearing operations on the dough during mixing. Maximum shear strength of the dough during mixing can be estimated from the records. Several configurations of the apparatus and typical dough- development curves obtained are shown. The accuracy and performance of the machine are discussed.
