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.

Abstract

The invention provides a method for drying roses and a rose product prepared by the method. The method for drying the roses comprises the steps that the roses are subjected to microwave or far infrared radiation, and first treatment roses are obtained; food desiccants are laid on a bottom layer, and the first treatment roses are spread on the food desiccants in a monolayer; after hot air circulation, warm-keeping and drying under 25-45 DEG C, second treatment roses are obtained; and the dried second treated roses are separated from the desiccants to obtain dried roses. According to the methodfor drying roses, the roses in the rose product are prepared; the water removing process has the characteristics of high efficiency, low energy consumption, and low aroma and nutrient loss; the dryingprocess is uniform and low in loss of rose color; and the rose products prepared by the method have the characteristics of rich flavor, good color and good shape.

Description

technical field [0001] The invention relates to the field of drying, in particular to a method for drying roses and rose products prepared by the method. Background technique [0002] Rose has rich cultural connotation and practical value. In addition to being used for viewing, it also has important development and utilization value in medicine, food and daily chemical industry. Rose flowers should not be stored for a long time after picking. In order to prolong the storage period and facilitate food or medicine, etc., they need to be processed. One of the most common treatment methods is to dry the roses to reduce the moisture in the roses and make the roses easy to preserve. There are many drying methods for roses, the common ones are natural drying, quick freeze drying and heating equipment drying. Among them, the natural drying method can save costs, but if it encounters rainy weather, the roses are prone to mold, resulting in a serious shortage of production, and beca...
