The invention provides a novel
processing method of radix Szechuan salviae miltiorrhizae, and belongs to the technical field of radix salviae miltiorrhizae
processing. The method comprises the following steps that firstly, strips of fresh radix Zhongjiang salviae miltiorrhizae are dug out, radix strips which have good quality and grow robustly are selected, sediments and stains on the surface of the radix salviae miltiorrhizae are cleaned away, water is drained after cleaning,
air drying is conducted to remove
moisture on the surfaces of the radix strips, the strips of the radix salviae miltiorrhizae are put into a slicer for
slicing, slices of the radix salviae miltiorrhizae after
slicing are put into a sterile tray and placed in order, the tray is put into a lyophilizer, and 17 stages are set for running, wherein the total consumed time is 60.05-90.05 hours, the first 10 stages are cooling and
icing stages, the last 7 stages are heating stages, vacuum sterilization is adopted for cooperation, through the stages from low temperature to normal temperature, in cooperation with the function of vacuum, active ingredients of the radix salviae miltiorrhizae can be 100% maintained without loss, and through the combination of low-temperature freezing and normal-temperature
drying, the active ingredients cannot be killed; in addition, through the cooperation of the sterilization effectat the low temperature, vacuum and normal temperature, the produced slices of the radix salviae miltiorrhizae are high in quality.
