An overview of the RDS Magazine Dryer
The system consists of a lock system at the inlet and the outlet, four heat zones, and a cooling zone. In order to achieve an atmosphere with low levels of oxygen, locks on the magazine are necessary where possible. A three-part handling process at the inlet and outlet guarantees that the compartments can open and close independently of each other. In this way, an inert process chamber is guaranteed in every loading situation. The magazines are transferred to the lock zones with a so-called lifting transport. During the loading process, the lifting transport unit with the hoist is lowered below the level of the transport chamber and simultaneously unloads the magazine onto this. The magazine is unloaded using the opposite principle. The magazine dryer prototype can be loaded and unloaded manually. The system is designed so that it can be fed using a handling system if necessary. Due to the flexible transport options, a small throughput during prototype production as well as a high throughput during future regular service is possible. Magazines with the maximum dimensions of 460 mm high, 240 mm wide and 240 mm deep can be transported using a three-part handling process with a base carrier plate. The cycle time can be a minimum of 3 minutes up to a maximum of 24 hours. There is good thermal separation from the process chamber due to the compartments and the 80 mm thick insulation. The exchange of hot and cold gas flows can be effectively prevented which results in lower electrical power consumption.
Loading of the magazines by hand or using a handling system in the goods carriers with exact positioning.
2. Lifting transport/inlet
A lifting mechanism feeds the magazines to the process chamber transporter.
A low level of residual oxygen in the N2-Tunnel is guaranteed due to the lock system. Compartments eliminate air leakage.
The four heat zones guarantee steady heating of all the components in the magazine at the lowest ∆ T.
Optimal thermal separation is achieved through a compartment between the heat and cooling zone. Cooling zone temperatures of 20 °C are possible.
The locks in the outlet area ensure a lower ppm value in the process chamber and a stable elevation profile.
7. Lifting transport/outlet
The magazines are transported to the outlet in the same way as the lifting transport at the inlet. The process chamber compartments remain closed.
