After picking the flower buds, use bamboo cages or baskets to hold them and immediately send them to the local purchase point for sale or processing; when the picking place is far away from the construction site, a temporary shade shed should be set up for drying, and avoid stacking them to prevent heat generation.

2. The method and standard of purchasing fresh rose buds: In the season of intensive purchase of fresh rose buds, the processing unit purchases fresh rose buds according to designated farmers.

4. Placing and loading of fresh rose buds: The selected fresh rose buds are evenly placed in the drying tray, the petals are uniformly downward or upward, the thickness is the same, do not squeeze; the drying tray is filled with flower buds When loading the car, handle with care, and the flower buds should not be deformed or worn.

5. Shrink drying of fresh rose buds: The drying cart filled with rose buds should be gently pushed into the drying room, the door of the drying room should be closed to heat up, the room temperature should be strictly controlled, the slow fire drying should be replaced in sequence, and the wind direction should be changed regularly. Make sure that the buds are evenly wet and dry, and the color is bright.

6.Rose bud drying: When the processing workshop is working normally, the room temperature is generally 50-75℃, and the drying process of rose buds from feeding to discharging takes about 8 hours. Manual detection of dried flower buds, as long as the color is bright and has the unique aroma of roses, the rose buds are full spindle-shaped, purple or sauce purple, the receptacle and calyx are yellow-green, and the flower buds are pink and flake when twisted by hand.

7.Grading, packaging and storage of dried rose buds: After being graded, dried flower buds are dried to room temperature, lightly put in a non-toxic plastic bag, tied and sealed, packed in a standard carton, and stored in a warehouse that meets hygienic standards. And keep the warehouse dry and ventilated. The packing box should be 20 cm away from the ground and the wall.

(1) Energy saving and low operating cost

Energy saving is the starting point of the initial application of the rosebud dryer, and it is also the main advantage. The efficiency of a traditional dryer is only 30%-50%, while drying with a rosebud dryer absorbs the hot and humid air generated during the dehumidification process and the heat in the surrounding air, greatly improving the energy efficiency of the unit, which can reach 150 ~250% energy efficiency, more than 50% energy saving than electric heating and drying, greatly reducing the company's operating costs.

(2) Good drying quality and beautiful appearance

The rosebud heat pump dryer is a gentle drying method, which is close to natural drying. The evaporation rate of surface moisture is close to the migration rate of internal moisture to the surface, so that the quality of the dried items is good, the color is good, and the product grade is high. The aromatic volatile substances obtained by the ordinary drying method retain less retention, the vitamins with poor heat resistance retain low retention, and the color change is greater. The rose bud roasting room can better maintain the original color, flavor and nutrition of the rose bud.

(3) Drying parameters are easy to control and have a wide adjustable range

During the drying process of the rosebud barn, the temperature, humidity and circulation flow of the circulating air can be accurately and effectively controlled, and the temperature adjustment range is from room temperature to 85°C, the relative humidity adjustment range is 15%-85%, and there are many varieties. Many kinds of different products are dried.

(4) Environmentally friendly and pollution-free

Material drying not only requires improving product quality and saving energy consumption, but also must be environmentally friendly. Based on the same evaluation criteria, the impact of rosebud barns on global warming is very small compared to the CO2 released by electricity. No harmful substances are produced during the drying process. Environmental friendliness is the advantage of heat pump drying. At present, foreign countries advocate the application of heat pumps to reduce CO2 emissions, and it will surely be further used.

Roses prefer sunny, cold-tolerant, drought-tolerant, well-drained, loose and fertile loam or light loam. They grow poorly in clay loam and bloom poorly. It should be planted in a well-ventilated place far away from the wall to prevent sunlight reflection, burn buds, and affect flowering.
