Patent CA-2299515-A1 (CA)
Title: Method and apparatus for measuring loss in weight of food products during processing
Inventor: WARDLE DAVID G
IPC: G01G3/16
Filed: 2000-02-25
Abstract: In the processing of food items a portion of the weight of the item is lost due to evaporation of a fluid or sublimation of a solid from the item during freezing or cooking. An apparatus having a absorbent weight attached to the end of an arm is used to indirectly monitor the change in the mass of food items during processing. Changes in the natural or resonant frequency of oscillation of the weighted arm provides data as to the change in the mass of the weight on the arm and, thereby, information as to the rate of change of the mass of food items during processing. This information may be used to determine how to make food processes more efficient in order to reduce loss in weight and, therefore, value of food items sold by weight. Alternatively, the method or the device could be used to compare the differences in yield between types of freezing, i.e., between mechanical refrigeration and cryogenics. Data collected by the device can either be downloaded through a data port to a computer or could be transmitted to a computer via a wireless link.
