Abstract
The invention discloses a chitosan reaction kettle comprising a reaction kettle body, a stirring device arranged in the reaction kettle body, a feeding port arranged on the top of the reaction kettle body, and a discharge port arranged at the bottom of the reaction kettle body. A motor is arranged above the reaction kettle body, and drives the stirring device to rotate. The rotation direction and speed of the stirring device are controllable. The stirring device extends into the reaction kettle body. Stirring blades are arranged on the end and on the middle part of the stirring device. Stirring baffles rotationally connected with the stirring blades are arranged at the suspended ends of the stirring blades. A scraper sheet is connected to the upper end of the stirring device. The scraping sheet is vertically positioned close to the inner sidewall of the reaction kettle body, and rotates under the driving of the stirring device. The chitosan reaction kettle provided by the invention has the advantages of reasonable structural design and sufficient stirring. With the reaction kettle, product quality can be effectively improved.
