The Sugar Oversaturation Monitor Model 970-M gives a simple, inexpensive, reliable and direct
measure of the most important variable in pan operation, syrup oversaturation. The 970-M
eliminates the need for precise vacuum control or complex calculations, enabling operators
with minimal experience to produce consistent, high-yield strikes of clean, more uniform
sugar. The 970-M improves centrifugal operation on all grades, giving better grain
characteristics which upgrade color and drying quality of finished sugars.
A sensitive resistance thermometer bulb in the measuring element senses vapor temperature and that reading is combined with that of a second matched bulb giving the temperature of water flashing to equilibrium at the same pressure. The two resistance values are resolved by the 970-M circuitry to produce the direct oversaturation indication and transmitted signal.
The 970-M utilizes the time-tested method of measuring temperature of vapor leaving the pan as the best indication of massecuite concentration at the upper surface. Since it is at the lowest temperature within the pan, it is at the point of highest oversaturation. This is proven as the one method capable of indicating unsafe oversaturation levels throughout the entire course of the boiling cycle.
The reliable indication of oversaturation provided by the 970-M replaces the far less reliable "feel" of even the most experienced sugar boilers. By following a few "good practice" rules of sugar boiling, vastly improved grain can be produced strike after strike for easy purging. This means less wash syrups and remelt sugars to be reboiled. It also means more time and pan capacity available for low grade syrup boiling to improve molasses exhaustion.
