Gold and silver drying
Release time:
The traditional drying method of honeysuckle is to use earthen drying room for baking, which has problems such as uneven quality, low drying efficiency and difficult to control drying temperature. It gradually cannot adapt to the large-scale, intensive, modern and seasonal development of honeysuckle industry and cannot adapt to the high-quality and fast-paced modern life.
Chinese herbal medicine processing enterprises With the development of mechanization, automation and scientific research information technology, the automated and intelligent high-temperature heat pump dryer has recently become a hot commodity for drying and processing enterprises. The air energy heat pump drying equipment is a mechanized and fully automatic type, which adapts to the needs of modern social development and changes the traditional outdated manual waiting, adding firewood, adding coal, turning over, measuring temperature and measuring humidity. It is a dryer with the highest cost-effectiveness in the current market, which is carefully designed and improved on the basis of the dryer that runs well in the current market through the combination of theory and practice. It can ensure that the dried material "honeysuckle" becomes natural green in color and full in shape, and the medicinal and nutritional components are not lost. It is fuller, better in color and higher in price than the products dried after killing. Compared with the traditional drying and airing method, the heat pump dryer can accurately control the temperature and humidity, has a high degree of automation, and does not require special supervision.
Honeysuckle processing steps:
1. First, determine the scale of the drying room according to the size of the planting area. Generally, each acre of honeysuckle requires a drying room of about 3 square meters, and the drying room is generally an insulation drying room made of polyurethane boards.
2. According to the performance of our company's equipment, a single 12-horsepower unit is equipped with a 30-cubic-meter drying room. The general external dimensions are 5mX3mX2m (4.8 meters long, 3 meters wide, and 2.2 meters high), and then the grill is made according to the indoor area. Each layer should leave enough space for air circulation.
3. In order to ensure the rapid drying and drying quality of honeysuckle, a static pressure cavity should be made in the drying room to make the air outlet more balanced, and the return air is designed in the middle of the top of the drying room to make the hot air flow more even and smooth.
4. When drying starts, the temperature is controlled at 30-35℃; after 2 hours, the temperature is raised to about 40℃; after 5-10 hours, the temperature is raised to 45-50℃ and maintained for 10 hours; finally, the temperature is raised to 55-58℃, and the maximum temperature shall not exceed 60℃. The total drying time is 24 hours. If the temperature is too high and the drying is too fast, the flower buds will turn black and the quality will decrease; if the temperature is too low and the drying time is too long, the flower color will not be bright and will be yellow-white, which will also affect the quality. On cloudy or rainy days, the flowers must be dried at a low temperature. First, dry them at 35℃-40℃ for 2-3 hours, then increase the temperature to 50℃ and dry them until they are 90% dry without damage. Generally, 6-7 kg of dried flowers can be used to make 1 kg of goods.
5. The drying standard is: it makes a sound when squeezed and breaks when crushed.
6. Whether it is drying or drying, the flower buds cannot be touched or turned by hand before they are dried, otherwise the flower buds will turn black, reduce the quality and affect sales.
7. The entire drying process is controlled by a microcomputer. The air-energy heat pump drying equipment adopts the most advanced balanced dehydration technology to maintain consistent dehydration inside and outside the material, so that the material is dehydrated at a balanced temperature, and the yield rate is close to 99.95%; the air-energy high-temperature heat pump dryer adopts a scientific baking curve and dehumidification curve to retain the internal nutrients of honeysuckle to the greatest extent, with good appearance color and full shape, which improves the market competitiveness of the product, and users can retain the moisture content of the material according to their needs. Under the premise of ensuring the quality of the dried material, the weight of the dried product is increased, and it is deeply loved by users! Honeysuckle has a natural color and full shape, does not damage the flower shape, does not destroy its natural medicinal effect, and does not lose nutrients. The equipment has a high degree of automation and does not require special supervision. The entire drying process is controlled by a microcomputer.
