The prompt
Create a conceptual 3D CAD model of a complete three-level rail-mounted hazelnut drying machine. Use millimeters. DRYING SYSTEM: - 3 drying levels. - 10 sliding trays per level, 30 trays total. - Each tray: 2000 x 1500 mm = 3 m². - Total drying area: 90 m². - Arrange each level as 2 rows of 5 trays. - Hazelnut bed depth: maximum 150 mm. TRAYS: - Frame: 40 x 40 x 2 mm square hollow steel tube. - Each tray has 5 internal transverse supports. - Floor plate: 1920 x 1420 x 2 mm. - Side walls: 200 mm high, 2 mm thick. - Keep trays open at the top. WHEELS AND RAILS: - 6 V-groove wheels per tray. - Wheel diameter: 100 mm. - Wheel width: 45 mm. - Axle bore: 20 mm. - 3 wheels on each side of every tray. - Wheel positions along the 2000 mm length: 250, 1000 and 1750 mm. - Rail center spacing: 1460 mm. - Rails: L40 x 40 x 4 mm steel angle. - V-groove wheels must sit directly on the upward-facing corner of the angle rails. - Allow each tray to slide approximately 1500 mm. - Add rail end stops. MAIN FRAME: - Heavy-duty rectangular steel structure. - Main columns: 80 x 80 x 4 mm square hollow steel tube. - Horizontal supports: 60 x 60 x 3 mm square hollow steel tube. - Tray rail levels approximately at Z = 600, 1400 and 2200 mm. - Approximate machine height: 2700 mm. - Size the frame around the actual 2 x 5 tray arrangement. - Keep all tray sliding paths clear. AIR SYSTEM: - Add a forced-air drying system. - One fan/heater unit feeds one main duct. - Split airflow into 3 parallel branches, one for each drying level. - Add air plenums below the trays so heated air flows upward through the tray floors. - Do not invent fan power, heater power or airflow values. DRIVE: - Add a conceptual geared-motor drive system for tray movement. - Do not use one motor per tray. - Show a centralized or level-based chain/shaft drive concept. IMPORTANT: This must look like a real industrial agricultural drying machine, NOT a storage rack or simple box. Clearly show 3 levels, 30 individual trays, rails, wheels, steel frame, air plenums, ducts, fan/heater unit and drive system. Keep major parts as separate components where possible. Do not invent unspecified engineering values.
