Industrial magnetic resonance food and other industries

Mobile single-sided NMR

“…Such magnets can be mounted in the production line for process control [525] or on the tip of an extruder in order to study the complex rheology of food pastes and fluids and to control and optimize the processing of food [154,526,527]. The viscosities determined by NMR imaging are in good agreement with those determined by conventional capillary rheometry (Fig.…”

“…Carbon-fiber reinforced material is hard to measure as it is conducting and shields rf, and the sensitivity of the NMR-MOUSE in the T 1q measurements needed for identification of thermal damage is too low [315,580]. On the other hand, the sensor can be used in the vicinity of steel, as some distortions of the magnetic measuring field can be tolerated [469,525,579].…”

“…49a) [184,579], and to identify defects by probing at suspicious positions, such as in glass-fiber reinforced components (Fig. 49b) [481,482,566] and solid rocket motor bond-lines [469,525]. Also the quality of processing could be identified, for example, on intact spools of synthetic fibers [582].…”
