How Does a Biscuit Packing Machine Work?

Biscuit packing machines have different parts and mechanisms that work together to properly package the biscuits. The packaging process typically involves:

• Feeding the biscuits into the machine
• Handling the packaging material like rolls of film or foil
• Orienting the biscuits so they are packaged uniformly
• Sealing the packaging material to create individual packs
• Cutting the sealed packs into individual units ready for distribution
• Discharging the packaged biscuits onto a conveyor belt or packaging line

Types of Biscuit Packing Machines

There are different types of biscuit packing machines available, each designed for specific packaging requirements. The common types include:

Flow-Wrapping Machines

Flow wrappers are commonly used to package biscuits. They work by continuously wrapping biscuits in packaging material. This creates sealed packs with tidy folded ends.

Flow wrappers are known for:

• High speeds – They can package a large volume of biscuits quickly.
• Versatility – They can handle biscuits of various shapes and sizes.

Because of these advantages, flow wrappers are suitable for many types of biscuits. They work by:

• Unrolling packaging film continuously from a roll.
• Detecting approaching biscuits using sensors.
• Wrapping the approaching biscuits with the moving packaging film.
• Sealing the film around the biscuits.
• Folding and cutting the film to form individual sealed packs.

Pillow-Pack Machines

Pillow pack machines are well-suited for packaging individual biscuits or small batches of biscuits. They use a single sheet of packaging material to form a pillow-shaped pack around the biscuits.

Pillow pack machines work efficiently and cost-effectively because:

• They use a single sheet of packaging material for each pack. This minimizes material usage and waste.
• They seal three sides of the pack at once, which is quicker than sealing each side individually.
• They can accommodate various biscuit sizes and shapes within the same pillow-shaped packs. This flexibility saves on production changeover time and costs.

Biscuit Cartoning Machines

Biscuit cartoning machines pack biscuits into cartons or boxes. They automatically put biscuits into the different compartments within the cartons.

Biscuit cartoning machines are typically used for:

• Family packs – Cartons containing several smaller packs of biscuits for the whole family.
• Bulk packaging – Large cartons containing many individual biscuit packs for stores and distributors.

Biscuit cartoning machines work by:

• Feeding biscuits into the machine. This can be from flow wrappers or other upstream biscuit packaging machines.
• Loaded carton feed system that supplies empty cartons to the machine.
• Placing the biscuits into their respective compartments within the carton.
• Sealing the carton once all compartments are filled.
• Discharging the filled and sealed carton.

Automatic Biscuit Packaging Lines

Automatic biscuit packaging lines combine several machines into one integrated system. They can automate the entire packaging process from start to finish.

Typically, biscuit packaging lines include:

• Feeding systems to move biscuits into the line
• Biscuit packing machines like flow wrappers or pillow pack machines
• Cartoning machines to load biscuits into cartons
• Case sealers to seal outer cases

Biscuit packaging lines offer:

• High automation – Machines work together with little or no human intervention.
• Increased productivity – The lines can achieve high packaging speeds.
• Customization – The lines can be configured to suit different biscuit types and pack sizes.

Biscuits move through each stage of the line automatically:

• Biscuits are fed into the line and packed by biscuit packing machines.
• Packed biscuits are loaded into cartons by cartoning machines.
• Loaded cartons are then packed into outer cases by case sealers.

Common Features and Components of Biscuit Packing Machines

Biscuit packing machines consist of various features and components that contribute to their functionality. Understanding these components can help you make an informed decision when selecting a machine. The key components include:

Feeding System

The feeding system of a biscuit packing machine feeds biscuits into the packaging process. It first supplies biscuits to the packaging machine at a steady rate.

Feeding systems usually consist of:

Vibratory feeders: Trough-shaped bowls that vibrate to move biscuits into the packaging machine one by one.

Conveyor belts: Continuous belts that transport biscuits at a controlled speed into the machine.

Rotary disc feeders: Rotating discs with pockets that pick up individual biscuits and release them into the packaging machine.

The type of feeding system depends on the design and requirements of the biscuit packing machine. For example:

• Vibratory feeders are good for fragile or oddly shaped biscuits.
• Conveyor belts can handle high biscuit volumes but may damage delicate biscuits.
• Rotary disc feeders offer consistent, even feeding of biscuits into the machine.

Packaging Material Handling

Biscuit packing machines use packaging materials like plastic films or metal foils to wrap the biscuits.

The machines handle the packaging materials in this way:

First, the packaging material is supplied in a roll.

Then the machine unwinds the packaging material from the roll.

Next, the unwound packaging material is fed through the packaging process. This means:

• Guiding the material through the machine
• Positioning it correctly around the biscuits
• Sealing it to enclose the biscuits
• Cutting it to form individual packs.

The machine handles different types of packaging rolls:

• Plastic films for moisture resistance and visibility
• Metal foils for barrier properties and heat reflection
• Laminated materials for strength and printability.

Sealing Mechanism

The sealing mechanism is what closes the packaging material securely around the biscuits.

Depending on the machine, sealing can be done in different ways:

Heat sealing: Uses heat and pressure to melt and join the plastic film together. This is a common sealing method for plastic films and laminates.

Ultrasonic sealing: Uses high-frequency vibrations to fuse and seal packaging materials like plastic and foil. It generates less heat than heat sealing.

Mechanical sealing: Uses mechanical forces alone to crimp and seal packaging materials together. No heat is involved.

The type of sealing mechanism depends on:

• The packaging material used – Some materials seal better with heat while others need ultrasonic or mechanical sealing.
• The biscuit type – More delicate biscuits require less heat, suiting ultrasonic or mechanical sealing.
• Manufacturers’ preferences – Different sealing methods have varying performance, efficiency and cost implications.
