Microwave drying application is conducive to automation of ceramic production

Microwave drying is completely different from traditional drying. It has the drying effect that traditional drying does not have, and it has broad application prospects in the fields of low-temperature drying and high-temperature heating in the daily-use porcelain industry. The use of microwave drying technology allows general ceramic bodies to be dried in a matter of minutes, and is less likely to cause deformation and cracking of the bodies. The application of microwave drying can shorten the drying time of the green body and reduce the drying space of the green body, which is conducive to the automation of the linkage with the previous and subsequent processes and the production.

Because of this, since the 1990s, the main ceramic producing countries in foreign countries such as Japan and the United Kingdom, although the main product production is still mainly based on rolling, but its technical content and degree of automation have been upgraded. Among them, especially in the continuous rollout of various rolling automatic lines, the drying equipment of the combined unit is more in the direction of rapid microwave drying. For example, microwave stripping dryers have been successfully used on the SKK roll forming equipment at FIGGJOA/S in Norway. The UK's microwave-vacuum drying and rolling or grouting equipment on-line form an automated production line, which not only improves production efficiency, but also ensures product quality.

The latest type of dryer is a microwave pulse dryer for daily ceramics, which will reduce the drying energy consumption and further improve the drying quality of the blank. There has recently been a study of a drying technology called “Solar Collectors,” which converts solar energy into a controlled hot gas stream for drying the green body. Its drying quality is good,

Easy to automate mechanized control. Each square meter of "solar collector" can collect 150,000 kcal energy, saving more than 70 kilograms of heavy oil.

Sandwich Panel Machine is a integrated production line consisting of a Roll Forming Machine and a sandwich panel laminating system. The roll forming machine and the laminating system can be operated separately. The roll forming machine consists of decoiler, main body and post-cut equipment. The laminating system consists of feeding, glue, heating, laminating and post-cutting.
The whole machine is under control of PLC.

The line can produce single corrugated sheet, and can also produce the sandwich panel with rabbet joint and sandwich panel.

The sandwich panel machine has two different systems: Pu sandwich panel machine and EPS sandwich panel machine according the different laminating Technology.
