Embodiment 1

[0012] The drying method of star anise of the present embodiment comprises the following steps: put the star anise that has been finished into a vacuum drying box, and the vacuum drying box at least transmits light into the box at the top; after closing the vacuum drying box, put the vacuum drying box Expose in the sun, when the temperature in the vacuum drying oven is as low as 65°C, heat the star anise to keep the temperature in the vacuum drying oven at 65°C; the entire drying time is 8 hours, during the drying process of exposure and heating Intermittent vacuuming to discharge the water vapor in the vacuum drying oven. Pumping for 5 minutes every 10 minutes in the first hour, 5 minutes every 20 minutes for the second hour, 5 minutes every 30 minutes for the third and fourth hours, and 5 minutes every 30 minutes for the second hour. 5 to 8 hours for 5 minutes every 45 minutes.

Embodiment 2

[0014] The drying method of star anise of the present embodiment comprises the following steps: put the star anise that has been finished into a vacuum drying box, and the vacuum drying box at least transmits light into the box at the top; after closing the vacuum drying box, put the vacuum drying box Expose in the sun, when the temperature in the vacuum drying oven is as low as 55°C, heat the star anise to keep the temperature in the vacuum drying oven at 55°C; the whole drying time is 14 hours, during the drying process of exposure and heating Intermittent vacuuming to discharge the water vapor in the vacuum drying oven, pumping for 5 minutes every 20 minutes for the first and second hours, pumping for 5 minutes every 30 minutes for the third and fourth hours, and pumping for every 45 minutes for the fifth to eighth hours 5 minutes, 5 minutes every 60 minutes from the ninth to fourteenth hours.

Embodiment 3

[0016] The drying method of star anise of the present embodiment comprises the following steps: put the star anise that has been finished into a vacuum drying box, and the vacuum drying box at least transmits light into the box at the top; after closing the vacuum drying box, put the vacuum drying box Expose in the sun, when the temperature in the vacuum drying oven is as low as 45°C, heat the star anise to keep the temperature in the vacuum drying oven at 45°C; the entire drying time is 20 hours, during the drying process of exposure and heating Intermittent vacuuming to discharge the water vapor in the vacuum drying oven, pumping for 5 minutes every 30 minutes for the first to third hours, 5 minutes every 45 minutes for the fourth to sixth hours, and every 60 minutes for the seventh to twelfth hours Smoke for 5 minutes, and smoke for 5 minutes every 60 minutes from the 13th to 20th hours.

Abstract

The invention discloses a drying method for star anise, and relates to the technical field of deep processing of agricultural byproducts. The method comprises the following steps of loading star anise subjected to deactivation of enzymes into a transparent vacuum drying oven in which an electric heating device is arranged, sealing the vacuum drying oven, exposing the vacuum drying oven under the sun, and when temperature in the vacuum drying oven is reduced to the set temperature, heating the star anise by virtue of the electric heating device, wherein the temperature in the vacuum drying oven is kept within a range of 45 to 65 DEG C; performing intermittent vacuumizing for 5 minutes every 10 to 60 minutes to exhaust water vapor in the vacuum drying oven in exposure and heating drying processes, wherein the whole drying time is 8 to 20 hours. The method is used for performing the drying processing on the star anise subjected to the deactivation of enzymes, and the problem that a conventional drying method for the star anise is long in treatment cycle and is easily influenced by weather is solved.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural by-products, in particular to a method for drying star anise after greening. Background technique [0002] Star anise is the fruit of the star anise tree. Its scientific name is star anise. It is a specialty of our country. It is rich in Guangdong, Guangxi and other places.
