Characteristics of Changzhou Paddle Drying Machine

Changzhou Fengneng Drying Engineering Technology Co., Ltd. has improved and optimized the wedge-shaped hollow blade dryer based on the absorption of excellent domestic and foreign technologies. It can indirectly heat or cool paste, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature calcination. The blade dryer launched by the company is a special wedge-shaped stirring heat transfer blade equipment, which has high heat transfer efficiency and self-cleaning function of the heat transfer surface. It has the advantages of low energy consumption, low operating costs, low material loss, and low pollution. Currently, this equipment is no longer used by food and drug production enterprises.

Paddle dryer is a horizontal stirring type dryer mainly based on heat conduction. Its name comes from the hollow stirring blades inside, which resemble ship paddles. This type of paddle dryer is widely used in the food, medical, pharmaceutical, smelting, organic or inorganic chemical industries. From a historical development perspective, blade dryers have been developed abroad for many years. The early blade dryer was developed by Germany, and later Japan introduced this technology and improved it, developing a series of products with dual axis and four axis structures and more than ten specifications. Due to the fact that the heat required for drying the equipment relies on indirect heating through thermal conduction, only a small amount of gas is needed to remove moisture during the drying process. This greatly reduces the loss of heat carried away by the gas and improves the utilization rate of heat. Therefore, the blade dryer is an energy-saving drying equipment. It is suitable for drying granular and powder materials, and can also smoothly dry paste materials, with a wide range of applications.

The equipment has a compact structure, a large heat transfer area per unit volume, and a small footprint, saving on factory construction costs. During the drying process of the blade dryer, the amount of gas used is small, the flow rate is low, and the amount of dust carried away by the gas is small. Therefore, the recovery of gas and dust after drying is convenient, and the recovery equipment volume is small, which can save equipment investment. For the drying process that requires solvent recovery, the solvent concentration can be greatly increased. Due to the special structure of the blade, the material undergoes alternating compression and relaxation during the drying process, which enhances the drying efficiency and ensures uniform moisture content of the product, thereby ensuring ideal drying results.

Compared to other countries, China's research on blade dryers is relatively late, and their applications are still in the exploratory stage, so many technical aspects are not yet mature enough. At present, many food and pharmaceutical industries in China have a high demand for hollow blade dryers. While introducing excellent foreign equipment, there are also many domestically produced blade dryer equipment that have emerged. These research and development and production enterprises have a high initiative in equipment research and development, strong learning ability, and attach importance to the cultivation of enterprise talents and the cultivation and exchange of technology. Therefore, they have manufactured a batch of blade dryer equipment that is suitable for the drying needs of China's industry and can basically meet the needs of China's industry.
