Abstract
The invention relates to a traditional Chinese medicinal technology, and especially relates to a fresh Salvia miltiorrhiza microwave drying technology. The fresh Salvia miltiorrhiza microwave drying technology comprises a step that a fresh Salvia miltiorrhiza medicine material is taken and undergoes microwave drying for 5-360min under conditions comprising that the temperature is 35-90DEG C and the pressure is normal pressure or a reduced pressure to obtain dry Salvia miltiorrhiza.
Description
Technical field:
The present invention relates to a kind of traditional Chinese medicine technology, particularly a kind of bright Radix Salviae Miltiorrhizae microwave drying technology.
Background technology:
Radix Salviae Miltiorrhizae has another name called Radix Salviae Miltiorrhizae, Radix Salviae Miltiorrhizae, Arisaema balansae Engl. etc.Be the dicotyledon Labiatae, dry root and rhizome.Main product in Anhui, ground such as Henan, Shaanxi.Effect: promoting blood flow to regulate menstruation, stasis-dispelling and pain-killing, removing heat from blood eliminating carbuncle, the relieving restlessness that clears away heart-fire, nourishing blood to tranquillize the mind.
The Radix Salviae Miltiorrhizae growth can be gathered medical material next year.Collecting time was excavated before sprouting for withered or spring in next year of overground part mid-December.Stem and leaf is removed on the ground earlier, opens a zanjon at furrow one end the ginseng root is exposed.Dig out complete root bar forward along furrow, prevent to dig disconnected.After digging out, cut off residual stem.Like need bar Radix Salviae Miltiorrhizae, can the root bar more than the diameter 0.8cm be downcut at the parent root place, manage along bar, tan by the sun, stir frequently, when doing very likely, be bundled into wisp, tan by the sun again to doing, case.
Drying processing for Chinese crude drug; Traditional handicraft often adopts modes such as oven dry, baking, natural drying, and its characteristics are material temperature by outside to inside raising successively, and dewatering speed is by outside to inside reducing gradually; The nexine water content is much larger than skin; Be prone to form dry shell, influence rate of drying and quality, cause the drying problems such as length, heating uniformity difference that expend time at skin.The characteristics of microwave drying are on the contrary; Be that material is successively to heat up from inside to outside; Dehydration is outside from the lining, so just is difficult for forming dry shell, and dehydration soon and evenly; A large amount of drying times and energy consumption can be saved, and Chinese crude drug can be effectively avoided because high temperature, the loss of active ingredients of being heated and causing for a long time.
Chinese crude drug itself often carries a large amount of microorganisms, before storage, without sterilization, is prone to cause a large amount of breedings of microorganism in the storage process, causes effective ingredient to be destroyed, and quality of medicinal material is caused great influence.The heat energy that microwave irradiation produces has the effect of microorganism killed and spore, is fit to the sterilization of liquid and solid material, and solid material is had desiccation.Be characterized in: microwave energy is penetrated into the deep of medium and material, but heating as one man in medium and the material table; And has low temperature, efficient, fast, advantages such as low power consuming, easy to operate, easy care.
Summary of the invention:
The present invention provides a kind of method for microwave drying of bright red rooted salvia, and this method also has the action of microorganisms of killing.
The method for microwave drying of bright red rooted salvia of the present invention may further comprise the steps:
Get bright red rooted salvia, obtain dried Radix Salviae Miltiorrhizae with microwave drying.
Wherein the condition of microwave drying is: temperature 35-90 ℃, drying time 5-360min, normal pressure or decompression.
The preferred wherein condition of microwave drying is: temperature 45-75 ℃, drying time 30-240min, normal pressure or decompression.
The condition of most preferred microwave drying is: power 12kw, 60 ℃ of design temperatures, drying time 60min, vacuum is not less than-0.085mpa.
Drying means of the present invention can also comprise the step with bright red rooted salvia water wash clean.
Therefore, drying means of the present invention, preferably following method
Method 1:
1, clean: with bright Radix Salviae Miltiorrhizae is raw material, washes silt, and bright Radix Salviae Miltiorrhizae is subsequent use.
2, drying: bright Radix Salviae Miltiorrhizae vacuum microwave drying, condition is: power 12kw, 60 ℃ of design temperatures, drying time 60min, vacuum is not less than-0.085mpa, promptly gets the dried medical material of Radix Salviae Miltiorrhizae after the drying.
Method 2:
Dry: bright Radix Salviae Miltiorrhizae vacuum microwave drying, condition is: power 12kw, 60 ℃ of design temperatures, drying time 60min, vacuum is not less than-0.085mpa, promptly gets the dried medical material of Radix Salviae Miltiorrhizae after the drying.
Drying means of the present invention and prior art relatively have obvious advantage:
Table 1 shows, this method drying weak point that expends time in, and material is heated evenly, and has effectively kept the active component in the medical material.
Table 1, sample moisture and part content information slip
And existing drying process adopts modes such as oven dry, baking, natural drying, has the drying problems such as length, heating uniformity difference that expend time in, and is prone to cause the loss of active component in the medical material.
Table 2 shows that clump count of the present invention obviously reduces.
Table 2, the cultivation test:
Table 3 shows that microwave drying can more effective reservation tanshinone and cryptotanshinone composition.
Table 3, sample moisture and part content information slip
Process of the present invention is effective, and technology is simple, is easy to promote.
