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.
