Gong Chrysanthemum Baking Drying Technology
The dried chrysanthemum stems are dried using baking techniques. Baking is a direct link to the quality of the product. 1. Drying room requirements: drying room area of ​​10 square meters or more, can not be ventilated inside the drying room, using charcoal fired baking oven, drying room need to set up ventilation holes in order to discharge moisture. With a simple pipe oven baking, combustion chamber mouth, flue crossing should be set in the drying room. 2. Roast cage drying. Charcoal fire should be covered with ash. It is better not to see open flames. The temperature should be appropriate. Strictly follow the operating procedures. Specific approach: The fresh flowers will be picked up (the number of flowers will not be able to see the gap is appropriate), and then placed in the drying room for the first round of tenderness baking (dry flower tenderness need to be baked for 2.5 to 3 hours. Wet flower needs 5.5 (6 hours), the temperature in the drying room is 40-50°C, and the temperature of the upper layer of the charcoal is about 80°C. The temperature reached the baking and drying temperature was about 53°C. The soil method was determined by hand on a baking oven and not hot. During the baking process, the fire and temperature should be checked frequently: if the temperature is too high, the flowers will be baked; if the temperature is too low, the color of the chrysanthemum will be discolored and the quality will be reduced. When the baking time reaches 90%, it will be transferred to the second round of baking. The temperature can be lower than 1/3 of the tender calf fire (30 ~ 40 °C), baking time is less than the first round (about 1.5 hours). When it's bake until it's green, it's time to take it off and take it out. Place in a dry and ventilated place. This baked fresh and white color, high quality and high price. 3. Easy pipeline drying. Use a scrap iron bucket as a fuel tank. A square hole is opened below one side of the bucket, close to the wall of the drying room, and is aligned with the inlet port left by the drying room wall to add fuel outside the room. Above the other side of the bucket, open a round hole and connect a curved iron exhaust pipe. The exhaust pipe leads to the outside of the drying room wall (it is also possible to connect a metal pipe with a fuel port). There are air holes on the wall of the drying room to distribute water vapor. There are brackets in the room. Multiple flower pots can be placed on the rack at the same time. The baking room is closed when baking, and firewood or anthracite coal is added in time (drying room temperature and time control are the same. Drying oven).
