The Tecno 350 valve bag filling machines are equipped with a vertical impeller bag filling system. Motorized rotation of the impeller moves product from the integrated loading hopper through the filling spout into the valve bag. A heavy-duty rubber hose connects the impeller housing with the filling spout. During the filling cycle and once target weight is reached, impeller rotation is halted and a pneumatically actuated clamping device stops product flow through the rubber hose and out the filling spout. The filling spout and bag support “float” from the main structure of the filling machine and are connected to the machine’s weighing system.

Each Tecno 350 is capable of a typical production speed of between 300-400 bags/hour. If higher production rates are required, a battery of up to 4 machines may be placed in line for production speeds of up to 1400 bags/hour.
The electric motor driven impeller is equipped with 4 vanes and housed in cast and watertight impeller housing eliminating any possible loss of product from the feeding system. The Tecno 350 is exceptionally well suited to packing very fine and dusty products such as cement, dry premix, calcium carbonate, gypsum, and powdered limestone. Tecno 350 valve bag fillers are equipped with an electropneumatic weighing system or optioned with an electronic weighing system.

Electropnumatic weighing systems, also known as scale beam weigh systems, are comprised of a lever, fulcrumed at the center, with one end connected to the filling assembly. The other end of the lever is connected to removable weights amounting to the target bag weight. The lever is also equipped with a readily accessible, easily adjustable counterweight system. The counterweight is used to fine-tune the target weight in 10gram increments.

Electronic weighing systems feature a filling assembly that is supported by load cell sensors connected to sophisticated electronics, which in turn translate load signals into relative, accurate data. A weigh system interface with membrane keyboard and digital display, allows for visualization of bag weights and all parameters that may be input into the weigh control system. The primary advantage of electronic systems lies in their ability to constantly self monitor and automatically correct for any changes product properties.
