The day lily is also known as yarrow, also known as day lily. It is rich in protein, fat, calcium, phosphorus, iron, and various micro-organisms. It has been planted both in northern and southern China. Lily should be steamed, dehydrated and dried immediately after harvesting. Due to the fact that day lily harvest season is in rainy and high temperature season, if only natural drying is used, there will be a lot of daylily because the weather does not dry in time, resulting in a decline in quality and even mildew, resulting in great economic losses. Therefore, the artificial drying of lily and the selection of a reasonable drying process and drying equipment are of great significance to the production of day lily. First, the processing process 1, the process of lily - steaming, drying, testing, measuring packaging, 2 points of operation lily picking: choose buds in the crack 1 to 2 hours before picking, when the production of lily, high quality it is good. Steaming: steaming is an important process in the processing of daylily. The buds harvested should be steamed in a timely manner. The steaming time is about 8 minutes, which means that the color is changed from yellow to green and the flower stalk starts to develop. Soft, hand buds have a slight buzz. Drying: Spread the buds after steaming evenly on the baking tray or drying on the drying oven. The drying temperature is 50°C～70°C, and the final moisture content is 14%. Inspection: After drying, the lily is selected and graded to remove debris. Metering and packaging: after inspection, use the packaging bag for measurement and packaging. Second, processing equipment (a) lily steaming device Steaming device is mainly composed of steamer, pot and stove, pot on the stove, steamer on the pot, steamer side door to put the spread of the network disk. When working, add water to the pan, and after the water is boiled, put a good mesh tray layer into the steamer and close the side door for steaming. After steaming, open the side door, remove the material and send it to the dryer for drying. (b) Drying equipment Day lily drying equipment, mainly drying rooms, box dryers, belt dryers and tunnel drying equipment. 1. The drying room is mainly constructed of brick and cement structure, with low investment and large amount of drying. However, there are problems such as uneven drying, difficult temperature control, low thermal efficiency, high energy consumption, and high labor intensity. 2. Box-type dryer, heat source is provided by hot air stove, and the materials are layered and loaded into the holding box. The hot air can pass through the materials in both forward and reverse directions through the reversing valve, which reduces the unevenness of drying. 3, belt-type flow dryer This equipment consists of feeding machine, drying room, spreader belt running mechanism and fan and other components. The heat source can be equipped with a hot air stove or a steam heat exchanger. The machine has continuous work, high drying strength, high degree of automation, uniform drying, and good drying quality. It is widely used in dehydrated vegetables and agricultural and sideline products processing industries, but its price is high and its one-time investment is large. 4. Tunnel type drying equipment The tunnel type drying equipment consists of drying tunnel, heat source, drying trolley and fan. The main body of the tunnel is a drying body. Most of them are brick structures, and a few are metal structures. The heat source is a hot blast stove, and it can also be heat exchanged by steam. During the drying, the loading trays are placed on the racks of the trolleys, and the trolleys enter from one end of the ramp and come out from the other end, and the materials can be dried during the movement. The device has the characteristics of simple structure, uniform drying, semi-automatic operation, low investment, and large amount of processing. It is widely used for drying vegetables, processing agricultural products, drying Chinese herbal medicines and native products. There are other types of equipment suitable for the drying of daylilies. Due to the fact that most of the equipment investment and usage costs during the drying process of the day lily are in the drying equipment and drying operation stage, a reasonable choice of drying equipment and drying process is a key. In the link, users can choose according to product quality requirements, output, and specific economic and production conditions.
