P307 Chocolate Coated Protein Bar Production Line: Compact Solution for Coated Snack Bar Manufacturing

Chocolate-coated bars are no longer limited to large-scale factories.
With growing demand for protein bars, fruit bars, and energy snacks, many manufacturers are looking for smaller, flexible production setups.

The P307 chocolate coated protein bar making machine is designed as a compact production line, integrating forming, coating, cooling, and packaging.

It targets:

• New food brands
• OEM snack manufacturers
• Pilot production lines
• Small to medium factories with limited space

The P307 is not a single machine. It is a modular production line composed of:

• Protein bar extruder
• Bar cutting unit
• Chocolate enrober
• Cooling tunnel
• Turning conveyor
• Flow wrapping machine

This setup enables a continuous process:

Forming → Cutting → Coating → Cooling → Packing

Each module can be configured based on production needs. (Shanghai Papa Industrial Co.,LTD)

The extruder uses a screw-driven system to push mixed ingredients through custom nozzles.

• Supports sticky and dense formulations
• Adjustable width and height
• Stable and continuous output

The cutter controls bar length via a control panel.

• Consistent product size
• Adjustable cutting speed
• Suitable for multi-shape production

The enrober applies chocolate in two main modes:

• Full coating
• Bottom coating

It can also be used for other coated snack products. (Shanghai Papa Industrial Co.,LTD)

Chocolate-coated bars are stabilized in a controlled cooling environment.

• Cooling down to low temperatures (up to -20°C range)
• Prevents deformation
• Improves surface finish and product integrity (Shanghai Papa Industrial Co.,LTD)

The flow wrapper includes automatic sorting and counting.

• Protects fragile and sticky bars
• Ensures consistent packaging speed

The capacity is suitable for small-scale continuous production and product testing. (Shanghai Papa Industrial Co.,LTD)

The P307 line handles a wide range of formulations:

• Protein-based mixtures
• Date paste and fruit blends
• Nut and seed inclusions
• Coconut and energy formulas

Typical products:

• Chocolate coated protein bars
• Fruit bars
• Energy bars
• Nutrition bars
• Date bars

(Shanghai Papa Industrial Co.,LTD)

Combines forming, coating, and packaging into one system.
Reduces coordination between separate machines.

Designed for startups and mid-scale production without high capital cost.

Modules can be added or removed depending on factory layout and budget.

Dedicated cooling system ensures coating quality, especially for chocolate-based bars.

Turning conveyor (e.g., 180°) allows layout adjustment in limited factory space. (Shanghai Papa Industrial Co.,LTD)

• Chocolate-coated protein bar manufacturing
• Fruit and date bar OEM production
• Functional snack brands entering coated product segment
• Factories upgrading from standalone extruders

This makes the coated version more suitable for finished product manufacturing rather than semi-finished bar production.

The P307 chocolate coated protein bar production line is designed for manufacturers who need:

• Complete processing from forming to packaging
• Stable coating quality
• Moderate capacity with controlled investment

It is not a high-speed industrial line, but a practical solution for:

• Product launch
• OEM production
• Small to medium-scale manufacturing

For buyers evaluating coated bar production, this type of integrated system reduces complexity while maintaining process control.
