MA 500 MISTRAL – MA 700 MISTRAL Manual packaging, with sealant and tunnel mounted on a single steel sheet structure, duly treated and varnished with epoxy powder. Official Distribution Certificate Operation The operation of these machines occurs by manually moving the product on the welding bar inside the film directly on the discharge plane. Welding is manually controlled. The beginning of the product in the tunnel takes place by pushing the next package, the development of the film will facilitate the "sleeping" closure of the product. The turbulence of hot air in the tunnel causes the film to retract until it takes the form of the product itself. The tunnel offers a high thermal efficiency compared to the reduced energy consumption. The machine is suitable for packaging different simple or multiple products, using its conventional hot weldable films. Made in various models, the machine has a low footprint, reliable practice. Main features Air recirculation tunnel with temperature controlled by bimetallic thermostat. Galvanized steel mesh conveyor belt, speed 3 mt / min. Sheet retraction chamber designed for positive heat transfer of the heating elements (bladed and winged) and for recirculation of hot air to minimize heat loss. Films used: flat polyethylene. Average output: 120/200 ppm / h (indicative as they depend on the type of product, the size of the product and consequently the packaging and the type of film used). Option Inverter for controlling the motion of the furnace conveyor, with speed adjustment. Cooling tunnel blower of the output product. Tunnel rollers. Tunnel conveyor belt with controlled timer. Conveyor with curved discharge rollers or line in various sizes. Extension of 400 mm band at tunnel outlet to stabilize products after retraction. Magnet for sealing the welding bar during welding operations.
