Brown-granulated-sugar re-dissolution constant current system

Abstract

The invention discloses a brown-granulated-sugar re-dissolution constant current system. The system comprises a honey extractor, a brown granulated sugar spiral groove, a brown-granulated-sugar re-dissolution box, a brown-granulated-sugar re-dissolution sugar-syrup pump and an evaporated floating-upward high-order sugar-syrup box. The above components are successively connected through a liquid conveying pipeline. A constant current control system is arranged between the brown-granulated-sugar re-dissolution box and the evaporated floating-upward high-order sugar-syrup box. The constant current control system comprises a re-dissolution box liquid level meter, a PLC constant current control box and a re-dissolution sugar-syrup flowmeter. The re-dissolution box liquid level meter and the re-dissolution sugar-syrup flowmeter are connected to a signal input terminal of the PLC constant current control box through a data channel respectively. A frequency converter is arranged in the brown-granulated-sugar re-dissolution sugar-syrup pump and is connected to a signal output terminal of the PLC constant current control box. The constant current control system can adjust a rotation speed of the brown-granulated-sugar re-dissolution sugar-syrup pump in real time according to a liquid level condition of the brown-granulated-sugar re-dissolution box and a re-dissolution pulp flow at an entrance of the evaporated floating-upward high-order sugar-syrup box. The system possesses characteristics that pumping efficiency is high and a flow velocity is uniform.

Description

technical field [0001] The invention relates to the field of sugar production control equipment, in particular to a brown sugar redissolution control system. Background technique [0002] Red granulated sugar remelting is an important process for processing red granulated sugar at present. The traditional red granulated sugar remelting and conveying process is: the brown sugar lamb is sieved by a honey separator to obtain red granulated sugar, and the red granulated sugar enters the red sand remelting box through a spiral groove. After adding High-temperature clear juice or hot water and fully stirred to obtain brown sugar redissolving syrup, which is directly pumped to the evaporation and floating high level tank by a non-blocking pump. The whole process only relies on manually adjusting the outlet valve of the non-blocking pump to control the pumping flow. The pumping efficiency is not high and the adjustment effect is not good, which often results in a mismatch between th...
