Using Papa P400 Multi-row Protein Bar Machine
Papa P400 Multi-row Protein Bar Extruder Machine is designed for efficient, large-scale production of a variety of functional protein bars, including chocolate coated protein bars. Follow the steps below to produce chocolate protein bars with consistent quality and great taste.
Step 1: Prepare the protein bar base
Ingredients (example):
Protein powder (e.g. whey protein powder, plant protein powder)
Oatmeal or crispy rice
Nut butter or syrup (as a binder)
Sweetener (honey, red dates or sugar-free syrup)
Cocoa powder or chocolate chips (optional, for flavoring)
Seasoning (vanilla, sea salt, etc.)
Directions:
Place all dry ingredients in a food-grade blender and mix.
Slowly add liquid binder until a sticky dough-like consistency is reached.
Make sure the mixture is firm but easy to shape.
Step 2: Feed Papa Protein Bar Machine
Load the prepared mixture into the machine's hopper.
The P400 extruder will form the bar via a customized nozzle mould with uniform width and the heigth,the lenght of the bar can be adjusted.
Multiple rows of rollers ensure even forming and minimize manual handling.
Step 3: Cooling and cutting
The form bar with desired width and heigth will go through a cooling tunnel (optional if the product is warm).
The integrated cutting unit cuts the formed bar into multiple rows of uniform bars - the cut size and number of rows can be adjusted via the control panel.
The bars are automatically separated and aligned on the conveyor for the next process.
Step 4: Chocolate coating (optional)
If chocolate coating is required, connect the output conveyor to the Papa 600 mm chocolate coating line.
The bars pass through a curtain of tempered chocolate for full coating or bottom coating only.
After coating, the bars enter a cooling tunnel for solidification.
Step 5: Packaging
The finished bars are conveyed to the packaging line.
Optional: Add automatic alignment and flow wrapping system for high-speed packaging.
