Abstract
The process of obtaining dry lactulose by spray drying is considered. The optimal parameters affecting the yield of the finished product, such as the mass fraction of lactulose in the solution, the drying temperature, the rate of supply of the solution and the rate of air supply are determined. It is shown that the solution with a mass fraction of lactulose (40±1) %is optimal for the production of lactulose powders. The highest yield of the product is obtained at a drying temperature equal to (140±1) °C, a solution feed rate of 0.0003-0.00042 m / h and an air flow rate of 15 m / h.Keywords
