地锦草颗粒一步制粒工艺研究

Study on one step granulation process for Euphorbia humifusa granular

为优化地锦草颗粒成型工艺,以颗粒的成型率、硬度、水分含量为考察指标,采用正交试验对影响地锦草颗粒一步制粒过程的因素进行考察。最佳工艺条件为:浸膏相对密度为1.20,喷雾速度为500 m L/min,雾化压力为0.4 MPa,进风温度为80℃。该工艺合理可行,适用于工业化生产。

The one step granulation process of Euphorbia humifusa granula was optimized by orthogonal test using produce ratio,solidity, water content as evaluation indexes. The proper technology was as follows： the relative density was 1.20, spraying speed was 500 m L·min^（-1）, atomization pressure was 0.4 MPa, inlet air temperature was 80 ℃. The process was reasonable, feasible and suitable for industrial production.
