Description
Technical Field
The invention relates to the technical field of sugar making equipment, in particular to a molasses continuous automatic heating and diluting device and a molasses continuous automatic heating and diluting method.
Background
The molasses that gets into the sugar boiling tank needs to be heated and diluted when the sugar refinery boils sugar, and traditional molasses heating dilution is put into the dilution box earlier molasses, then adds water and adds steam, and the mixer that starts simultaneously dilutes. The above heating dilution method has the following disadvantages:
(1) the diluted molasses and the water adding amount are not accurately measured, and the dilution concentration is uncontrollable.
(2) The molasses is generally heated in a steam loop mode, local overheating of the molasses is easily caused to increase color when convection circulation is poor, even caramel is generated, and the quality of finished sugar in the later period is seriously influenced.
(3) Because the temperature of the molasses cannot be monitored in real time, the temperature of the molasses is not controlled stably, and the temperature of the sugar boiling feeding material cannot be reached frequently, so that the sugar boiling energy consumption is increased.
(4) The traditional molasses after being heated and diluted is stored at high temperature and low concentration, so that the sugar conversion loss is increased.
(5) Under the high-temperature and high-humidity environment, 1-2 workers are used per shift, boxes, tanks and valves are various, and the workload of maintenance is large.
(6) Most of the molasses sticky box is a non-closed box body, and the molasses sticky box is attached to the upper wall of the box body and is not cleaned in time, so that bacteria are easy to breed, and the food sanitation and safety are affected.
(7) Sugar grains in the molasses cannot be dissolved in time, the sugar grains which cannot be dissolved participate in crystallization again after entering a sugar boiling tank, and finally a large amount of uneven finished sugar grains are generated, and fine uneven particles finally enter the molasses to participate in heating dilution circulation. The sugar crystal grains in the diluent A are not completely dissolved, the sugar crystal grains in the original A can enter the original A when the sugar is not well absorbed during boiling, the sugar crystal grains in the original A can enter the original B when the sugar is not well absorbed during boiling, the sugar crystal grains in the original B can not be completely dissolved, and the sugar crystal grains in the original B can enter the waste honey when the sugar is not well absorbed during boiling. Finally, the waste honey directly enters the sugar boiling process, which is a great loss.
