| titleOfInvention | Preparation method and system of solid lactic acid |
| abstract | The present invention provides a method and system for preparing solid lactic acid. The specific preparation includes the following steps: S1. Concentrating and evaporating the food-grade L-lactic acid solution in a vacuum state and under heating conditions, until the lactic acid content in terms of monomolecular lactic acid is 103-105%, 90-120 ℃ thermal insulation for later use; S2, pour the lactic acid solution into the container, add calcium oxide powder, stir and mix within 2 minutes, let stand for solidification for 10 minutes, remove the container, and leave the material at room temperature for more than 3 days , until it is completely solidified and non-sticky; the solidified materials obtained in S3 and S2 are cut and crushed by a slicing machine to obtain granular materials, which are then pulverized and screened, and an anti-caking agent is added to mix evenly to obtain the finished solid lactic acid powder. During the preparation of the present invention, the drying process of first preparing calcium lactate can be omitted, the high energy consumption of the screw extruder and drying can be reduced, and the problems of large investment in solid lactic acid powder production equipment and high energy consumption in the drying process can be solved. The method provided by the invention has less dust emission, high production efficiency and low production cost. |
