Description
Technical Field
The invention relates to the field of processing of radix ranunculi ternati decoction pieces, and in particular relates to a high-efficiency drying process of the radix ranunculi ternati decoction pieces.
Background
Ranunculus ternatus thumb is dried root tuber of Ranunculaceae plant Ranunculus japonicus Temminck. The decoction pieces are spindle-shaped, shaped like cat's claws, and have tawny residual stems or stem marks at the top. The surface is yellow brown or gray yellow, the color becomes dark after long-term storage, and the hair has slight longitudinal wrinkles, a bit of fibrous root marks and residual fibrous roots. Firm, white or yellowish white, hollow or solid, powdery in cross section. Light smell, slightly sweet taste.
The existing processing method mostly takes raw medicinal materials, removes impurities and non-medicinal parts, cleans with water, and dries. The drying method is divided into sun drying, oven drying and freeze drying, and the former two are the main, for example, Chinese patent CN110559397A discloses a processing and drying method for traditional Chinese medicine decoction pieces, which comprises the following steps: s1, selecting the rhizoma gastrodiae which is completely cleaned and has no damage and mildew; s2, steaming the preferred rhizoma gastrodiae in the S1 for 10 to 25 minutes in a steamer at 90 to 100 ℃; s3, slicing the gastrodia elata steamed in the S2 to be transparent; s4, uniformly placing the sliced rhizoma gastrodiae in the S3 on a drying net, and tightly attaching the drying net to a covering net; s5, feeding the rhizoma gastrodiae slices placed in the S4 into a dryer for drying; the drying includes primary drying, uniform drying and thorough drying. This a processing drying method for herbal pieces-has ensured the gastrodia elata property of a medicine through chooseing for use high-quality gastrodia elata, has reached the even effect of drying through section stoving, through preliminary stoving, even stoving and thoroughly drying, has guaranteed that the moisture content of sliced medicinal herbs is low, ensures that the sliced medicinal herbs can not lead to the sliced medicinal herbs to milden and rot because of moisture is too much to can't eat, has ensured the safety and sanitation of sliced medicinal herbs through germicidal treatment, makes the safe edible of consumer relieved.
In the method, in order to thoroughly dry the root-tuber type traditional Chinese medicine decoction pieces, a slicing and multi-step drying method is adopted, and although the dried traditional Chinese medicine decoction pieces are finally obtained, the time consumption is extremely long, the efficiency is low, the drying time for reaching the expected water content is long mainly due to the fact that the water in the root tuber is slowly evaporated and the drying temperature is low, the medicinal part of the ternate buttercup root is also the root tuber, the time consumption in the drying or drying process is long, the efficiency is low, and the production of the decoction pieces is seriously influenced.

The hot ventilation device comprises an air heater 7 and an air outlet groove 71, wherein the air heater 7 and the air outlet groove 71 are symmetrically arranged on two sides of the mounting frame 4. The needle head 31 and the mounting plate 3 are made of stainless steel. The diameter of the needle 31 is 1mm, and the arrangement interval of the needles 31 is 1/3 of the average root diameter. The average root diameter processed in this example was about 3 mm.
The specific processing process is as follows:
firstly, feeding fresh radix ranunculi ternati roots drained with water into a supporting plate 8 through a feeding hopper 6, turning on a vibration motor 9, vibrating while feeding until a layer of roots is uniformly paved on the supporting plate 8, stopping feeding, turning on an air cylinder 2, repeatedly lifting a mounting plate 3 to enable a needle head 31 to penetrate through a through hole 51, downwards needling the roots on the supporting plate 8, pricking a plurality of needle holes on the roots, pressing down the mounting plate 3 for the last time, piercing the roots through the needle head 31, turning off the air cylinder 2, not pulling out the needle head 31, turning off the vibration motor 9, turning on a resistance heater 32, heating the needle head 31 to 60 ℃ through the mounting plate 3, carrying out endogenous heating, volatilizing the water from inside to outside through the needle holes rapidly, turning on a hot air heater 7, blowing hot air at the temperature of 80 ℃, blowing the hot air through the roots on the supporting plate, blowing out from an air outlet groove 71 and the feeding hopper 6, carrying out external drying, discharge of steam and the drying of root tuber surface shallow layer with higher speed, dry when being less than 10% to the water content of root tuber, on lift syringe needle 31, the root tuber on the syringe needle 31 is under the blockking of material returned board 5, withdraw from syringe needle 31, drop on layer board 8, pull out all four pins 82 in both ends afterwards, upset layer board 8, dry drink on the layer board 8 is followed layer board 8 one side blanking, collect the storage and be the root tuber that dry cat claw grass sliced medicinal herbs will dry and arrange the invariable shady and cool place cooling of humiture in, sealed package saves can.
Example 2: the rest of the process was the same as example 1 except that the diameter of the needles was 0.5mm, the distance between the needles 31 was 1/2 which was the average diameter of the root tuber, the temperature of the needles was 70 ℃ and the temperature of the hot air was 90 ℃. The average root diameter processed in this example was about 2 mm.
Example 3: the rest of the process was the same as example 1 except that the diameter of the needles was 1.5mm, the distance between the needles 31 was 1/3 which was the average diameter of the root tuber, the temperature of the needles was 60 ℃ and the temperature of the hot air was 100 ℃. The average root diameter processed in this example was about 2.5 mm.
Comparative example 1: the radix ranunculi ternati decoction pieces with the water content lower than 10% are prepared by adopting a hot air drying method at 85 ℃.
The water content and the drying time of the ternate buttercup root decoction pieces of the examples 1-3 and the control example 1 are counted, and the results are shown in the table 1:
TABLE 1 moisture content and drying time of Ranunculus ternatus
| Group of | Water content of decoction pieces (%) | Drying time (min) |
| Example 1 | 6.6 | 50 |
| Example 2 | 5.4 | 70 |
| Example 3 | 5.9 | 60 |
| Comparative example 1 | 6.5 | 140 |
| Example 1 | 8.7 | 45 |
| Example 2 | 7.4 | 45 |
| Example 3 | 8.1 | 45 |
| Comparative example 1 | 46.2 | 45 |
As can be seen from the results in Table 1, the same water content was achieved after the additional steps of needling and endogenous heating of the needle head, the time required by the present invention was significantly shortened, and the water content of the prepared pieces of decoction was significantly reduced for the same drying time.
The cat claw grass root is punched with the plurality of needle holes through the needle head, so that the inside moisture is favorably emitted when the root tuber is dried, meanwhile, the needle head penetrates into the root tuber to heat, the moisture is favorably volatilized from the inside to the outside, and the cat claw grass decoction pieces can be quickly dried by matching the inside and the outside with a thermal ventilation device, so that the finished product has low water content and high efficiency. The vibrating motor can be used for single-layer feeding, and can also turn over the root block in the needling process, so that the needling uniformity is ensured.
In conclusion, the invention can obviously improve the drying efficiency of the root tuber, shorten the drying time and reduce the water content of the decoction pieces.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical scheme according to the technical idea proposed by the present invention falls within the protection scope of the present invention; the technology not related to the invention can be realized by the prior art.
