● Variable manufacturing data, such as the production number, the best-before date, the batch number, etc. are adapted by exchanging the separate reception via which are especially designed for this purpose.

● Printing temperature, printing time and printing pressure are adjustable.

Control precision（±0.5℃）.x

● The automatic printing film supervisory unit (odometer to determine the film feed) ensures a machine stop in case the printing film has run out or teared off, and thus ensures a constant bag printing.

● The printing film reception rolls are equipped with a pneumatic, hand-operated clamping. So the printing film can be exchanged very easily and without any special tool, the time required for service purposes is reduced to a minimum.

● In order to ensure that the bag film does not adhere to the printing film subsequent to the printing process, the bag film is held down by pneumatic film clips.

For changing the printing block, only two clamps have to be released. The block reception must not be removed if you have to change the characters of the production and best-before date, the batch number, etc.

-03- Film Transfer with Film Opener

The film transfer is performed by an electric motor driven linear gear unit. During the transfer, the film is held by pneumatic film clips. When the film is fed in, the two film layers are opened with a fixed opener taper key in the front area, where the next step, i.e. the port insertion, will be carried out.

-04- Contour Welding and Cutting Station

This station is used for welding the outer contour of the bag, for adhering the ports to the bag film and for cutting the outer contour of the bags. The welding is done by exchangeable welding tools provided with heating cartridges to produce the required welding temperature.

Welding time, pressure and temperature are adjustable.

Control precision（±0.5℃）.

The welding temperature is verified within a defined min./max. range by the PLC control unit and temperature sensor, in order to ensure a permanently correct welding process.

In case the welding temperature remains under or exceeds – for any reason whatsoever – the defined min. / max, range, the machine will stop. Simultaneously, an error message is displayed in the control panel.

※ Using the unique design of the heating plate and mold separation, replacement of mold is extremely simple.

※High-precision processing technology, don't adjust the mold.

-05- Port Pre Heating Station

This station serves for pre-heating the ports up to a certain temperature before they arrive between the two bag film layers of the contour welding station, and thus it ensures an optimal welding of port and bag film. For this, two pre-heating tools which are pre-heated to a certain temperature and having the same contour as the ports, are brought together on the port. Pre-heating temperature and time can be adjusted via the control panel.

※Using the unique design of the heating plate and mold separation, replacement of mold is extremely simple.

-06- Port Feeding with Feeder Bowl and Buffer

3. CIP and SIP  

The CIP/SIP units of the machine can be ordered optionally.

It is consisting of automatic function of CIP / SIP including steaming bar and drain pipes for condensate water. The outlet valves of drain and steam are to open manually.

● CIP(Clean in Place)

After the rinsing process has been started from the filling station control panel by manual operating, the filling nozzle will move downward into the cleaning and steaming bar. The filling nozzle at the different filling locations are sealed with a silicone gasket in the cleaning and steaming bar. The cleaning fluid flows from the product connection through the surge tank into the product distributor. From here, the cleaning fluid flows into the different filling locations, through the mass flow, the product tube and through the filling valve into the cleaning and steaming bar. From here, the cleaning fluid flows through two outlet tubes into a drainpipe beneath the filling station. After cleaning, the filling nozzle returns to its original position.

● SIP(Steam in Place)

After the cleaning of the machine the steaming process will begin at a temperature of about 125 °C. After the steaming process has been started from the filling station control panel by manual operating, the filling nozzle will move downwards into the cleaning and steaming bar. The filling nozzle at the different filling locations are sealed with a silicone gasket in the cleaning and steaming bar. The filling valves are opened and the superheated steam moves from the product connection trough the surge tank into the product distributor. From here the superheated steam moves into the different filling locations, through the mass flow, the product tube and through the filling valve into the cleaning and steaming bar. Inside the cleaning and steaming bar, two side-mounted temperature probes (PT - 100) monitor the temperature during the cleaning process. From here, the superheated steam moves through two outlet tubes into the drainpipe beneath the filling station. Two stop valves are located on the left and on the right hand side of the drainpipe. Beneath stop valve a approx.1 mm diameter aperture is located. Through this gooseneck the superheated steam condenses into water. This condensate is finally let out through a drainpipe. At the end of SIP process the filling nozzles will stay in the sterile steaming bar and wait for set up or next production to ensure sterile conditions of the whole filling system.
