Describes the combination sculls leaves and tray drying system drying processes, the device structure and working principle, the energy consumption of its good use and environmental resistance were analyzed and compared, it affirmed this combination compared to conventional drying system flash convective drying compositions in the industrial production of barium salt rationality and significant energy savings.

In the rising prices of raw materials, particularly the recent sharp rise in copper prices, the profit margin linear air conditioning rotary compressor industry decline. In early 2005, the industry is still in the sales margin level of close to 15%.

Currently serving the chemical industry drying equipment notable feature is the role of technology content have become increasingly prominent. This is the last sale of products by price competition has been very different. Among them, some of the drying equipment with high technical content, focusing on the development of new products manufacturers, increasing efficiency upgrade; on the contrary, lower technological content of products, new products and new technology development capacity is weak companies, benefits begin to decline.
