Embodiment 1

[0036] 1. Select fresh roses from the production area that meet the environmental quality technical specifications of the green food production area as raw materials;

[0037] 2. Impurity removal and cleaning: remove the rotten roses in the fresh roses, and clean the fresh roses in clean water;

[0038] 3. Pre-freezing stage: Quick-freeze the material to below the eutectic point of the material, specifically: put the above-mentioned material on the tray, turn on the compressor to pre-refrigerate the drying room, and after about 15 minutes, the temperature of the shelf board in the drying room reaches -15°C , put the material tray in the refrigerated vacuum dryer, and then set the freezing temperature to -40°C, and the freezing time is subject to the material temperature reaching -25°C, which is 20 minutes in this embodiment;

[0039]4. Vacuum drying: The specific operation is to turn on the vacuum pump to vacuum the water trap first, then vacuum the drying chamber after the ma...

Embodiment 2

[0045] The difference from Example 1 is:

[0046] In step 4), turn on the compressor to refrigerate the shelf in the drying room. After the plate temperature reaches -13°C for 10 minutes, place the material tray in the freezer vacuum dryer, and then set the freezing temperature to -30°C. The freezing time is when the material temperature reaches -28°C. ℃ shall prevail, and the present embodiment shall be 30 minutes;

[0047] Step 5) Keep the vacuum degree of the drying chamber at 17Pa, and the vacuum degree of the water trap at 12Pa; maintain the temperature of the water trap at -50°C; during the vacuum drying process, the temperature of the shelf board is increased linearly by 8°C per hour. The limit temperature of heating is 40°C; after 10 hours, the sublimation is completed; when the temperature of the material is stabilized at 35°C, the desorption process is terminated; at this time, the moisture content of the material is 3%;

[0048] Step 8) Processing parameters in sup...

Embodiment 3

[0051] The difference from Example 1 is:

[0052] In step 4), turn on the compressor to refrigerate the shelf in the drying room. After the plate temperature reaches -16°C in 14 minutes, place the material tray in the freezer vacuum dryer, and then set the freezing temperature to -40°C. The freezing time is when the material temperature reaches -28°C. ℃ shall prevail, and the present embodiment shall be 15 minutes;

[0053] Step 5) During the vacuum drying process, the linear temperature increase of the shelf board is set to increase by 12°C per hour; the vacuum drying process is completed after 15 hours; at this time, the moisture content of the material is 2%;

[0054] Step 8) Processing parameters in superfine pulverization: gas consumption 15m 3 / min, air pressure 0.8mPa, air velocity 450m / s, classifier wheel speed 10000r / min.

[0055] Step 9) Collecting the finished product, the finished product has a particle size of 1500-2500 mesh and a moisture content of 6%.

Abstract

The invention relates to a method for preparing rose superfine powder, which comprises: taking medicinal and edible fresh rose as a raw material, and performing impurity removal, cleaning and vacuum freeze-drying; and coarsely crushing the dried rose raw material, applying fluidized bed pneumatic milling technology for superfine processing, and preparing superfine powder products with water content between 6 and 8 and granularity between 1,000 and 3,000 meshes. The products produced by the method have the characteristics of uniform granularity, good dispersity, no processing pollution, capability of reserving bioactive compositions and thermosensitive compositions to the maximum degree, and not only can be quick to take health care effect and complete to absorb and digest but also can reduce the dosage and greatly improve the utilization rate of nutritive compositions of the rose.

Description

technical field [0001] The invention relates to a superfine powder processing technology of biological materials for nutrition, health care, medical treatment and daily cosmetics, in particular to a preparation method of rose superfine powder. Background technique [0002] Rose (Rosa rugosa Thumb.) is a deciduous shrub belonging to the Rosaceae family. Roses are native to my country and have a long history of cultivation. There are written records about roses as early as the Han Dynasty. Rose resources are widely distributed, from Guangdong in the south to Shenyang, Liaoning in the north, Shanghai, Jiangsu, Zhejiang, and Shandong in the coastal areas in the east, and Henan, Gansu, and Xinjiang in the inland west. Among them, Gansu, Sichuan, Jiangsu, Shandong, Beijing, Henan, Hebei, Liaoning, Heilongjiang, Taiwan, Shanxi and Xinjiang are the main ones. [0003] The advantages of roses planted in Shenyang, Liaoning are: cold resistance, barren resistance, disease resistance,...
