Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine processing technology, specifically to a processing method and apparatus for processing Atractylodes lancea based on dynamic circulation of rice water. Background Technology

[0002] Atractylodes lancea is the dried rhizome of Atractylodes lancea or Atractylodes dasycarpus, belonging to the Asteraceae family. It possesses the effects of drying dampness and strengthening the spleen, dispelling wind and cold, and improving eyesight. Clinically, it is widely used for dampness obstructing the middle jiao (middle burner), abdominal distension, diarrhea, edema, beriberi, rheumatic pain, colds due to wind-cold, and night blindness. Common processing methods for Atractylodes lancea include stir-frying with wheat bran and soaking in rice water. Among these methods, processing with rice water is a traditional and effective approach. Rice water processing can mitigate its drying properties, reduce its pungent and warming side effects, and enhance its stomach-soothing effects.

[0003] For example, patent application number CN201911132613.X discloses a method for preparing Atractylodes macrocephala by rinsing it with rice water, including the following steps: (1) Stir-fried Atractylodes lancea with wheat bran: First, preheat the pot, then pour wheat bran into the hot pot and simmer for 2-5 minutes. Add Atractylodes lancea slices and stir-fry quickly. After stir-frying, pour out the dried medicine.

[0004] (2) Dry medicine processing: Pour the stir-fried dry medicine into a medicine sieve for sieving, let it cool to room temperature, spray with honey water, and put it into the factory warehouse for cold storage.

[0005] (3) Rice water: Crush rice with a grinder, filter the rice with a filter screen, add it to water and cook it to obtain rice water.

[0006] (4) Soaking Atractylodes: Take out the refrigerated Atractylodes and soak it repeatedly in rice water. After soaking, take it out and put it in an oven to dry.

[0007] (5) Concentration: The dried Atractylodes lancea is ground into powder in a grinder, and then the filtrate is repeatedly extracted in 80% ethanol and concentrated under reduced pressure to obtain concentrated Atractylodes lancea paste.

[0008] (6) Packaging: Fill the concentrated Atractylodes lancea paste into bottles and store it in a refrigerator at 4-6℃.

[0009] In step (4), the soaking temperature is 20-25℃, and the rice water is changed every 7-8 hours, for a total of 8-10 times. This solution has the following problems: First, the treatment process is complicated; second, the treatment time is very long, reaching 60-100 hours, and changing the rice water also takes time; third, the rice water needs to be changed constantly, making the operation complicated; fourth, the amount of rice water used is large, resulting in high costs and a large volume of wastewater to be treated.

[0010] For example, patent application number CN200610043766.3 discloses a process for processing rice water, which is as follows: soak Atractylodes lancea in water, change the water every 3-5 hours, change the water 5-6 times, then soak it in rice water for 20-50 hours, then add black beans and steam for 30-90 minutes, and finally take out Atractylodes lancea for dehydration and crush into powder for later use.

[0011] This patent requires pre-soaking in clean water and repeated water changes, which consumes a lot of water resources. In addition, the soaking time of the rice water in this patent is long, and the total processing time is long, reaching 50-80 hours, when combined with the soaking time in clean water.

[0012] In summary, the traditional method of processing Atractylodes lancea with rice water has many problems. On the one hand, it mostly involves static soaking, resulting in insufficient and uneven contact between the rice water and Atractylodes lancea, leading to poor and unstable processing results and making it difficult to guarantee the consistency of quality for each batch. On the other hand, the long soaking time in rice water makes the rice water highly susceptible to environmental influences, causing it to deteriorate and spoil, thus affecting the quality of the Atractylodes lancea. Summary of the Invention

[0013] This invention provides a processing method and apparatus for processing Atractylodes lancea based on dynamic circulation of rice water. By dynamically circulating the rice water, sufficient and uniform contact between the rice water and Atractylodes lancea is achieved, improving the processing effect and ensuring quality stability. The technical solution provided by this invention is as follows: On one hand, embodiments of the present invention provide a processing method for Atractylodes lancea based on dynamic circulation of rice water.

Attached Figure Description

[0025] Figure 1 This is a flowchart of the processing method for Atractylodes lancea based on dynamic circulation of rice water disclosed in an embodiment of the present invention. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below.

[0027] Example 1 Example 1 provides a processing method for Atractylodes lancea based on dynamic circulation of rice water, including the following steps: (1) Preparation of rice water: Weigh 5kg of high-quality rice, grind it in a grinder and pass it through a 100-mesh sieve. Mix the obtained rice flour with 50L of water. Put the filtered rice flour and water mixture into a cooking device and cook it at 30℃ for 12 minutes to obtain rice water. Cool the rice water for later use. (2) Dynamic circulation processing: Take 1 kg of Atractylodes lancea slices and put them into the processing container. Add 10 kg of the prepared rice water, turn on the stirring device, and control the stirring speed at 50 rpm. At the same time, start the circulation device to make the rice water circulate dynamically in the processing container at a flow rate of 1 L / min. The temperature is controlled at 30℃, and the processing time is 8 hours.

[0028] (3) Drying treatment: After processing, Atractylodes lancea is taken out of rice water and placed in an oven to dry at 60°C for 8 hours. Testing revealed that this batch of processed Atractylodes lancea contained 0.28% atractylodesin and 0.06% atractylone, with all indicators meeting quality standards. The testing methods followed the Chinese Pharmacopoeia.

[0029] Example 2 Example 2 provides a processing method for Atractylodes lancea based on dynamic circulation of rice water, including the following steps: (1) Preparation of rice water: Same as in Example 1. (2) Dynamic circulation processing: Take 1 kg of Atractylodes lancea slices and put them into the processing container. Add 9 kg of the prepared rice water, turn on the stirring device, and control the stirring speed at 45 rpm. At the same time, start the circulation device to make the rice water circulate dynamically in the processing container at a flow rate of 1.2 L / min. The temperature is controlled at 32℃, and the processing time is 8 hours.

[0030] (3) Drying treatment: Same as in Example 1.

[0031] The test results showed that the atractylodes content in this batch of processed Atractylodes lancea products was 0.26% and the atractylone content was 0.06%, which met the quality standards.

[0032] Comparative Example 1 uses the traditional static soaking method to process Atractylodes lancea, and the process is as follows: (1) Take 1 kg of Atractylodes lancea slices and put them into a container. Add 10 times the amount of rice water and soak at 30℃ for 8 hours without changing the rice water.

[0033] (2) After soaking, take Atractylodes lancea out of the rice water and put it in an oven to dry at 60°C for 8 hours. Tests showed that the batch of processed Atractylodes lancea contained 0.2% atractylodesin and 0.09% atractylone.

[0034] Comparative Example 2 uses the traditional static soaking method to process Atractylodes lancea, and the process is as follows: (1) Take 1 kg of Atractylodes lancea slices and put them into a container. Add 10 times the amount of rice water and soak at 30℃. Change the rice water every 8 hours for a total of 8 times.

[0035] (2) After soaking, take Atractylodes lancea out of the rice water and put it in an oven to dry at 60°C for 8 hours. Tests showed that the batch of processed Atractylodes lancea contained 0.27% atractylodesin and 0.08% atractylone.

[0036] Comparative Example 1 shows that short-term soaking of rice water is not effective; Comparative Example 2 shows that the method provided by this patent has similar effects to long-term, multi-batch soaking of rice water, but with atractylone content is lower.

[0037] The same batch of Atractylodes lancea was processed 15 times according to the method of Example 1 and 15 times according to the method of Comparative Example 2. The results are shown in Table 1. Table 1

[0038] As shown in Table 1, for atractylodesin, the maximum difference in Example 1 was 0.04%, while that in Comparative Example 2 was 0.06%; for atractylone, Example 1 showed almost no fluctuation, while Comparative Example 2 showed greater fluctuation. This indicates that the processed product of this patent is more stable and has better consistency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
