The Magnoni division of the LM group has developed a special water removal system for a particular packaging: the pouch, which is the plasticized pouch used for protein beverages, fruit juices, pet food and animal feed.
Starting from the blowing system for tinplate containers and traditional bags, a consolidated technology in the range of Magnoni systems, a new product has been developed. This is more suitable for difficult packaging such as pouches, whose bottom is much more difficult to dry.
The production of this packaging involves the insertion on the packaging line of pouches that arrive a little damp or wet, as they come from a pasteurizer. The blower’s task is precisely to remove any residual water to make them arrive dry at the packaging station.
The machine consists of a blowing tunnel of about 3.8 meters, with air flow management controlled by appropriate sensors. It is completely made of Aisi 304 stainless steel. Inside the tunnel there are two conveyors: a lower and an upper one to create a “sandwich” effect, with special straps that hold the product to contain it during passage and drying. The belts, with a width varying from 200 to 2000 mm, are made of high-drainage metal mesh, also in Aisi 304 stainless steel. The blower is equipped with an upper and a lower blowing blades with adjustable position and inclination to facilitate blowing on the product. The machine is designed for both single-row and multi-row products.
The covers can be inspected on both sides and insulated high-vent chimneys are provided for noise attenuation. Photocells are provided at the inlet and outlet to detect the flow of the pouches.
The power of the fans is calibrated according to the degree of dryness required and also to the type of product inside the pouches (which clearly must not be altered).
LM’s pouch blower is able to remove more than 99% of water.
The particular design allows you to effectively manage products with heights ranging from 1 mm up to 30 mm without the need for any format change.
