Chrysanthemum drying process

Chrysanthemum not only has ornamental value, but also has considerable medical value. In recent years, the demand for chrysanthemums at home and abroad has been increasing year by year, and the market prospect of chrysanthemum.At present, the flower farmers will sell the chrysanthemums to large and medium-sized cities at home and abroad through processes such as picking, drying and vacuum packaging. However, the traditional chrysanthemum drying process is not satisfied with the high quality of materials, and the emergence of the Dryfree high temperature heat pump dryer has completely overcome this problem.

In order to save costs, the traditional chrysanthemum manufacturing process is through sulfur fumigation. This traditional drying method destroys the surface wax. However, the current state of this process has been banned. However, it is not excluded that individual farmers still use traditional sulphur fumigation drying processes to dry chrysanthemums. The chrysanthemum produced by this process can only be used for bathing and foot care, not edible or pharmaceutical. At present, another traditional drying of chrysanthemum is by steaming and drying,this method easy to cause the petals to be excessively dried and the petals to fall off. The quality of the dried chrysanthemums is not up to the requirements, the color of the flowers cannot be guaranteed, and the storage is also easy to be eaten by the insects in the later stage. And the dried chrysanthemums are easily broken. Obviously, this is not the best way to dry chrysanthemums.

Introduction of high temperature heat pump chrysanthemum drying equipment

The heat pump dryer of Dryfree only needs a small amount of electric energy to drive. A large amount of heat is absorbed from the air through the dryer. It is transported to the drying room by the circulating fan, and the cycle is rapidly heated (the adjustable temperature in the drying room is: 8°C-80°C, adjustable humidity: 5%-95%), and then the wet exhaust damper is used to drain the water. Achieve the purpose of material drying. It adopts microcomputer intelligent temperature control and humidity control. The drying process requires no specialists to guard, no pollutants are discharged, and the running electricity cost is low. It is an energy-saving and environmentally-friendly drying solution.

Using Dryfree high temperature heat pump drying machine to dry chrysanthemum

Before drying chrysanthemum, the tray will be packed well and put into the drying oven smoothly. It can not overlap, so as to avoid unnecessary air leakage caused by bad placement of the tray. The dryer is preheated to 45 50 C. The chrysanthemum is loaded into the drying tray and placed in the drying chamber drying tray bracket. Then the temperature is raised to 65 ~75 ℃. Because chrysanthemum has high requirements on color, fragrance, shape and taste, the original color, flavor and taste after drying are required. This requires that the pyrene head be dried strongly after ripening, while the petal part is dried weakly. At the same time, the high temperature heat pump dryer is used to dry chrysanthemum, which can reduce energy consumption and operation cost effectively. Effectively avoid the phenomenon of drying or excessive drying caused by manual operation, reduce labor intensity and operation cost.
