Abstract

The invention relates to a microwave sensitive online detect method and a relative detector on the cane juice crystallization super-saturation degree. The invention uses a cane juice saturation sensitive inductance winding in 8-shape or dual-6 shape to connect a microwave signal excite circuit, wherein the winding can change resistance along with the capacitor and inductance change of around medium, to change the microwave frequency generated by the microwave signal excite circuit. The excite circuit is compacted with the outer wall of a boiling pan, to check the change of microwave frequency, to obtain the super-saturation of cane juice. The detector comprises a microwave signal excite circuit, a microwave frequency check and voltage convert circuit, a microprocessor, a power supply and a display. The microprocessor stores the relation between the microwave frequency electric parameter signal and cane juice crystallization saturation, to directly output the cane juice crystallization super saturation degree according to the microwave frequency. The inventive method and the detector can non-contact detect the cane juice un-saturation degree in the boiling pan, with simple application, strong interference resistance, high measurement accuracy and wide measuring range.

Description

(1) Technical field

[0001] The invention relates to a method and a device for detecting the crystallization concentration of sugarcane juice, in particular to a non-contact microwave induction on-line detection method and a detector for crystallization supersaturation of sugarcane juice. (2) Background technology

[0002] The sugar industry is an important industry related to the national economy and the people's livelihood, and sucrose is the main sugar product. Sucrose is crystallized from concentrated sugarcane juice. The process of extracting refined sugar from sugarcane juice is still very backward, and the most important process step - the crystallization of sucrose solution, commonly known as the sugar boiling process, is far from being automated. This also makes the energy consumption of the sugar industry high, the cost is high, and the sales price is difficult to drop. It also directly affects the profit of the manufacturer,
