Q & A

What is the importance of controlling process variables like temperature and pressure in an industrial installation?

Controlling variables such as temperature and pressure is crucial to ensure high-quality products. These variables help maintain the desired process conditions, and in case of deviations, actuators like motors or control valves adjust the process to correct the parameters.

How is temperature regulated during beer brewing in the Brouwerij Bourgogne de Flandres?

During beer brewing, the temperature is monitored via sensors in the brewing kettle. The measured value is compared to the desired temperature, and control actions, such as pumping hot or cold water through a heat exchanger, are taken to maintain the correct brewing conditions.

What role does pH play in the brewing process, and why is it important?

pH or acidity levels are important in the brewing process because they affect the saccharification of malt to sugar, which impacts the final yield of the brewing process. Maintaining the correct pH ensures proper fermentation and the desired flavor of the beer.

How does the operator control the thickness of packaging film at Amcor?

The operator controls the thickness of the packaging film by setting the desired film thickness on a control screen. Sensors measure the flow rate of plastic pellets, and the system adjusts the extrusion speed and the composition of different layers to ensure the correct film properties.

What ensures that the flow of plastic pellets to the extruder is uninterrupted at Amcor?

Weighing hoppers serve as buffer reservoirs to ensure an uninterrupted flow of plastic pellets. A level control system monitors the amount of material, and when the pellet volume drops below a set threshold, a valve opens to replenish the hopper.

How is the tension of the film regulated during its transport in the Amcor production process?

The film tension is regulated by controlling the speed of the rollers during transport. Servomotors adjust the speed differential between the rollers to maintain consistent tension, preventing wrinkles and ensuring smooth transport.

What system ensures the film remains centered during transport at Amcor?

The film's lateral position is monitored using a fork sensor system, which ensures the film stays in the middle of the transport path. This system prevents the film from shifting to the sides, which could cause defects.

How is viscosity controlled in the adhesive application process at Amcor?

Viscosity is controlled using a vibration sensor, which monitors the viscosity of the adhesive. When the value deviates from the set point, the sensor triggers a valve to add more solvent, ensuring that the adhesive maintains the correct consistency.

What is the role of ion exchange columns in the gelatin production process at Roelo?

Ion exchange columns are used in the gelatin production process to remove ions and adjust the pH of the gelatin. Positive ions are first exchanged for hydrogen ions, lowering the pH, and then negative ions are swapped with hydroxyl ions, raising the pH again, resulting in the desired gelatin consistency.

How is collagen sterilized during production at Roelo, and why is this important?

Collagen is sterilized by heating it above 138°C for at least 5 seconds using superheated steam. This process is crucial to ensure that the collagen is safe for consumption, free of bacteria, and suitable for use in food, medicine, and biomedical products.
