Drying method of flos chrysanthemi

Abstract

The invention provides a drying method of flos chrysanthemi. The drying method of the flos chrysanthemi comprises the steps of adopting a hot air drying room as a drying device which comprises a drying room, a drying support and a hot air generation furnace; spreading fresh flos chrysanthemi on a table surface of the drying support in the drying room, wherein the spreading thickness is 8 to 10cm;starting the hot air generation furnace, adjusting the temperature in the drying room to be 25 to 35 DEG C, and keeping for 3 to 4 hours; then, adjusting the temperature in the drying room to be 55 to65 DEG C, keeping the temperature for drying for 18 to 19 hours; and then, closing the hot air generation furnace, and when the temperature in the drying room is reduced to be 40 DEG C, transferringthe flos chrysanthemi from the drying room so as to obtain the dried flos chrysanthemi with the water content being 8 to 12 percent. According to the drying method of the flos chrysanthemi provided bythe invention, the hot air drying room is adopted for drying the flos chrysanthemi, so that a natural fragrance is maintained, and no bitter taste exists in the flos chrysanthemi; through two-step temperature-control drying, the effective nutritional ingredients of the flos chrysanthemi are not damaged, and the shapes of the flos chrysanthemi are complete; and the dried flos chrysanthemi has tenacity, is not easy to break, and is crystal yellow and bright when being soaked in water.

Description

technical field [0001] The invention relates to a method for drying chrysanthemums. Background technique [0002] In the existing production of chrysanthemums, the drying of fresh chrysanthemums is done in the sun, and the chrysanthemums taste good, but they are restricted by the weather, which affects work efficiency and takes a lot of work and time. Or use the heat of burning firewood, charcoal or coal to dry quickly, there are following defects: uneven temperature, difficult to control the humidity; During the drying process, chrysanthemum is easy to absorb impurities, causing pollution and bitter taste. Contents of the invention [0003] In order to keep the shape of the dried chrysanthemum intact without losing petals and keep the natural fragrance of the chrysanthemum, the invention proposes a drying method for the chrysanthemum. [0004] For this reason, the technical scheme of the present invention is: a kind of drying method of chrysanthemum, it is characterized...
