A mixture of lactitol in fine powder, from 100 to 50 mesh, and air, in a mixing ratio of 10-20%, v/v, is injected from the center nozzle of a two-fluid nozzle attached on the top of a spray-drying tower. Separately, a 75% aqueous sucrose solution which is cooled gradually with agitation and which is beginning to crystallize is sprayed through the outer nozzle applying a pressure of 50 to 100 kg/cm2 to allow the sprayed solution to contact with powderd lactitol and then the mixture is dried with hot air charged from the top of the drying tower. Alternatively, a sucrose solution as described above may be sprayed on a horizontal fluidized-bed of lactitol fine powder, and the lactitol powder and the sucrose drops may be dried as a whole to obtain a crystalline sucrose-lactitol product. The mixing ratio of sucrose and lactitol is adjusted to meet the degree required for the product as table sugar.
