Embodiment 1
[0044] The drying method of roses, the steps include:
[0045] A Fresh rose buds picked before 7:00 in the morning are screened by a sorting machine, and then manually selected again to obtain roses; roses are treated with microwaves for 2 minutes under the condition of rose power per gram of roses for 2 minutes, and the first processed roses are obtained flower;
[0046] Lay desiccant for food on the bottom layer of B, spread the first treatment rose single layer on the desiccant; hot air circulation and variable temperature drying, temperature control method includes drying at 35-40°C for 4 hours; drying at 40-45°C for 6 hours; Cool to 35-40°C and dry for 4 hours; cool to 30-35°C and dry for 3 hours; cool to 25-30°C and dry for 2 hours; heat up to 30-35°C and dry for 3 hours; heat up to 35-40°C and dry for 4 hours; heat up to 40-40°C Dry at 45°C for 9 hours to obtain the second treated rose;
[0047] C. separating the dried second treated roses from the desiccant to obtain...
Embodiment 2
[0050] On the basis of the steps in Example 1, the parameters of the microwave treatment process in step A were changed, specifically, the roses were treated with microwaves for 5 minutes under the condition of a power of 12W per gram of roses.
Embodiment 3
[0052] On the basis of the steps in Example 1, the microwave treatment process parameters of step A were changed, and infrared radiation treatment was added, specifically, roses were treated with microwaves for 1.5 minutes under the condition of 8W power per gram of roses; at the same time, the power was 1kW, and the radiation distance 30cm, the loading density of roses is 1kg / m 2 Under these conditions, the far-infrared radiation treatment is 1.5min.
