Frequently Asked Questions by Customers

1. What bar sizes can the protein bar making machine produce?

For normal sizes, we can customize the nozzle as long as the bar width is within 150mm, and for larger sizes, we can customize the conveyor.

2. What power supply do you need to prepare for the protein bar machine?

Customers only need electricity of the correct voltage to match our protein bar machine, an air compressor to produce compressed air and daily water. No need to prepare any other power supply.

3. I haven't made the bar yet, can you provide us with the bar formula?

Papa Industrial is an expert in food machinery and protein bar machine manufacturers, but we are not an expert in making food bars. With more than ten years of global protein bar machine manufacturing experience, especially our Indian protein bar making machine and American protein bar making machine, and hundreds of times testing customers' snack bars, we can provide customers with some basic bar formulas. In addition, we are willing to help and develop formulas suitable for customers.

4. Do you have certification for protein bar machines?

For protein bar machines, we have CE certification, and we can also provide specific certifications according to customer requirements, such as SASO in Saudi Arabia.

5. Does the protein bar machine require installation and training?

If the customer needs it, our engineers can install it at any time; because the protein bar machine is small in size, it is fully packaged and sent to the customer, so there is no need to install it; in addition, the protein bar machine is fully automatically controlled by a PLC system with a touch screen, and it can be easily operated through digital operations on the screen. We have detailed instructions and operation videos for customer training; finally, we have a service team to support online services. If the customer needs our installation and commissioning services, we will arrange visa applications and dispatch engineers.
