Pseudo-ginseng drying process

Abstract

The invention discloses a pseudo-ginseng drying process. The process comprises the following steps: sorting the pseudo-ginseng, removing the big root and the fibrous root, rinsing by a high pressure gun or washing by a hairbrush cleaning device, rinsing for 3 times, freezing, performing quick-freezing, and performing sublimation drying and desorption drying to obtain the product. The pseudo-ginseng dried through the process provided by the invention has the advantages of crisp taste, low water content, no decay within 5 years, panax notoginseng saponins content higher than that of the routine process, no mud impurity or other impurity, high hygienic index, low colibacillus and total coliforms, smooth epidermis without crack and good commodity.

Description

technical field [0001] The invention relates to the technical field of drying technology, in particular to a notoginseng drying technology. Background technique [0002] Panax notoginseng has a cultivation history of more than 400 years. For hundreds of years, Panax notoginseng has been dried in the sun according to the general traditional Chinese medicine drying process. In the late 1980s, with the promotion of flue-cured tobacco cultivation in Wenshan, the main production area of ​​Sanqi, it began to appear. Dry the Panax notoginseng in a barn with flue-cured tobacco. The application of panax notoginseng drying technology has largely solved the adverse effects of long-term rainy days on the drying of panax notoginseng, but due to the uneven temperature in the drying room, the quality of the roasted panax notoginseng is difficult to guarantee. After 2008, with the continuous expansion of the planting area of ​​notoginseng and the improvement of the benefits of notoginseng ...

Problems solved by technology

The application of notoginseng drying technology has largely solved the adverse effects of long-term rainy days on the drying of notoginseng, but due to the uneven temperature in the drying room, the quality of the roasted notoginseng is difficult to guarantee

Panax notoginseng dried by these processes has the following disadvantages: 1. The product is extremely hard, and it is very inconvenient to eat and take; 2. The drying time is long; 3. The drying is not thorough, and the moisture content is high, which is not conducive to storage; 4. It is affected by the weather. Conditions are limited, and the continuous rainy weather will cause the corruption of Panax notoginseng and cause great losses; 5. During the long-term drying process, the active ingredients (total saponins of Panax notoginseng) and nutrients will be lost due to factors such as enzyme activity; 6. The pre-treatment cannot remove more soil and other impurities, the pesticide residues are high, and the hygiene indicators are poor; 7. Because the efficacy of raw and cooked Panax notoginseng is not the same, there is no uniform standard for baking temperature, resulting in inconsistent product quality ; 8. Panax notoginseng can be polished with talcum powder and paraffin to cover up product defects; 9. The skin and interior moisture content of the product is uneven, and the moisture content is high on the inside and low on the outside. It is easy to cause mildew and deterioration during storage
