Tecno FF weighing-bagging machines are equipped with force flow, pneumatic pressure bag filling systems, and are designed for use with non free flowing products in either powder or granular form. Product is fed into and contained in the machine’s cylindrical hopper, which is pressurized with an air compressor through a filtration system. The bottom of the hopper is cone shaped and then specially molded for a smooth transition to the filling spout, guiding the pressurized product into the bag.

The coned portion of the hopper is equipped with pressurized air pads, which assist with fluidification of the product and its flow into the bag. A heavy-duty rubber hose connects the cylindrical hopper with the filling spout.

During the filling cycle, a pneumatically actuated clamping devise regulates the aperture of the hose for dual phase filling modes (COURSE feed and FINE feed). Once target weight is reached, the 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. The Tecno FF is capable of a typical production speed of between 350-450 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 1600 bags/hour.
