| Experimental project | Colour(s) | Smell(s) | Fruit shape |
| Example 1 | Reddish brown | Strong fragrance | No black and mildew |
| Example 2 | Reddish brown | Strong fragrance | No black and mildew |
| Example 3 | Reddish brown color | Strong fragrance | No black and mildew |
| Example 4 | Reddish brown | Strong fragrance | No black and mildew |
| Example 5 | Reddish brown color | Strong fragrance | No black and mildew |
| Comparative example 1 | With black or brown colour | Light fragrance | Has black and mildew |
| Comparative example 2 | Dark brown | Light fragrance | Black and mildew-free |
| Comparative example 3 | Brown colour | Light fragrance | No black and mildew |
| Comparative example 4 | Brown colour | Light fragrance | No black and mildew |
| Comparative example 5 | Light brown | Light fragrance | Has black and mildew |
| Comparative example 6 | Light brown | Light fragrance | No black and mildew |
As can be seen from Table 1, the obtained aniseed by using the continuous drying device and the process of the embodiments 1 to 4 of the invention has the advantages of brownish red or reddish brown color, strong fragrance, no black and mildew of fruit shape and good quality.
Compared with the example 3, the aniseed is poor in color, fragrance and fruit shape when the comparative example 1 is dried at 80 ℃ and in a high-humidity environment and the comparative example 2 is dried at a temperature of 85 ℃ and a lower humidity; the reason is that the comparative examples 1-2 are only provided with one drying interval, which is equivalent to constant-temperature drying without enzyme deactivation, so that the dried aniseed has lower quality.
Compared with example 3, comparative example 3 and comparative example 4 are dried by the steps of reducing the intermediate temperature and humidity respectively, the star anise drying reaction is not completely carried out, the color and the fragrance of the star anise are light, and the fruit shape is not obviously changed; comparative example 5 was dried without intermediate temperature and humidity transition, and the color of the aniseed was lighter and less fruity than comparative examples 3 and 4.
Compared with example 3, comparative example 6 adopts a traditional batch drying method under the same temperature and humidity conditions, the enzyme deactivation and drying are firstly carried out, the drying environment is constant at 80 ℃ and high humidity, the drying reaction can not be completely carried out, and although the fruit shape is not obviously changed, the color and the fragrance are poor.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Those skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
