The Infeed/Outfeed Conveyor is an integral mechanical subsystem of a Depyrogenation Tunnel, designed to automate the material handling process. Its primary role is to precisely transfer containers (such as glass vials, syringes, or ampoules) into the tunnel's heating zones for the depyrogenation (pyrogen removal) process and subsequently convey the treated items out of the tunnel for further downstream processing like filling or capping. It ensures a continuous, controlled flow of materials, maintaining the tunnel's sterile barrier and process efficiency. The conveyor typically operates using a motor-driven belt or chain mechanism. For the infeed section, it receives containers from an upstream source (e.g., a washer), aligns them, and transfers them at a controlled speed into the tunnel entrance. The outfeed section receives the depyrogenated containers from the tunnel's exit, often cooling section, and transfers them to the next station. Speed is synchronized with the tunnel's main conveyor to maintain proper spacing and prevent jams. Systems often include sensors for position detection, jam prevention, and integration with the tunnel's control system. Constructed from stainless steel (AISI 304 or 316L) and food-grade conveyor belt materials (e.g., silicone, PTFE-coated fabric), the conveyor is designed for cleanroom environments. Key parameters include rated load capacity (50–200 kg/m), conveyor speed (0.5–10 m/min), belt width (200–1200 mm), conveyor length (1000–6000 mm), motor power (0.25–2.2 kW), operating temperature (-10–60 °C), ingress protection (IP54–IP65 per IEC 60529), power supply (380–480 V AC, three-phase, 50/60 Hz per IEC 60038), belt material (PU, PVC, SS304), frame material (SS304, SS316, CS), noise level (≤70 dB(A) at 1 m), and overall dimensions (1000–6000×500–1500×800–1200 mm). These values are reference ranges and must be verified for the specific model and application. The conveyor is a component, not a standalone machine, and its performance depends on integration with the tunnel and upstream/downstream equipment. Always confirm model-specific specifications and standards with the legal manufacturer or supplier.
The conveyor uses a motor-driven belt or chain to move containers. Infeed receives containers from upstream, aligns them, and transfers at controlled speed into the tunnel. Outfeed receives treated containers from the exit and transfers to next station. Speed is synchronized with the tunnel's main conveyor to maintain spacing and prevent jams. Sensors detect position and jams, integrating with the control system.
