Embodiment 1
[0044] A method for preparing anhydrous lactose microcrystals by customizing the α / β ratio, comprising the following steps:
[0045] S1. The lactose raw material is fed from the upper part of the α / β ratio regulation unit 1, and the ratio regulation of α / β-lactose is carried out under ultrasonic and temperature control conditions;
[0046] S2. The α / β-lactose solution in a fixed ratio is spray-dried and granulated in the spray and anhydrous lactose coarse particle separation unit 2, and the spray lactose coarse particle separation is completed;
[0047] S3, the sprayed lactose fine particles are separated in the anhydrous lactose fine particle separation unit 3, and the obtained sprayed lactose coarse and fine particles are collected;
[0048] S4. Coarse and fine sprayed lactose particles are mixed with an organic solvent in the anhydrous lactose microcrystal growth unit 4 to form anhydrous lactose microcrystals with a customized α / β ratio.
[0049] The α / β ratio control cham...
