[0002] Lactitol is a polyol produced by hydrogenating lactose. It is characterized by low calories, no increase in blood sugar, and prevention of tooth decay. It is widely used in food (such as sugar-free candy and baking ingredients), medicine (such as laxatives) and chemical industries. Its physical form is a white crystalline powder with a particle size usually between 5-100 μm. It is easy to form dust in the dry state.
[0003] According to the published patent for dust recovery device with announcement number CN107620971A, a combustion furnace is included. A retractable base plate is installed at the bottom of the combustion furnace. One end of the base plate is fixed to the inner wall of the combustion furnace, and the other end is inserted into a positioning groove in the inner wall of the combustion furnace. A collection pit is provided below the combustion furnace to recover the dust generated after combustion. A recovery air duct is installed on the collection pit leading to a transfer box. The retractable base plate automatically allows the dust to fall into the collection pit, thereby improving dust recovery efficiency. However, the following problems still exist:
[0004] The equipment is difficult to screen before recycling dust. If there are impurities in the dust, the quality of dust recycling may be poor. Therefore, we provide an environmentally friendly dust recycling device for lactitol production. Utility Model Content
