This mixed candy packing machine focuses on reducing equipment investment while retaining accurate total-weight control. It is intended for general candy assortments rather than fixed four-component recipes.

Lower Investment with One Weighing System

All four candies are combined before weighing, allowing one standard 14-head multihead weigher to handle the complete portion.

Compared with independent component weighing, this structure requires fewer weighing sections, collection devices and recipe controls. It also reduces the size and complexity of the support platform.

The lower cost comes from simplifying the weighing process, not from reducing the accuracy of the final bag weight.

Four-Feeder Premixing

Each candy type has its own vibratory feeder. The four feeders operate simultaneously and release the products into one shared conveyor.

Feeding rates can be adjusted during product testing to improve the average distribution of the four candies. However, the feeders do not weigh or verify the amount of each candy in an individual bag.

Stable refilling is important. If one feeder runs empty or its output changes, the composition of the following bags may also change.

Simpler Operation and Maintenance

Using one weighing system means fewer hoppers, discharge paths and control settings for operators to manage.

The simpler structure can also reduce:

• Cleaning time
• Recipe setup work
• Spare-parts requirements
• Routine inspection points
• Maintenance workload

This is especially useful when the factory mainly produces one general four-candy assortment and does not require frequent precision recipe changes.

1. Can this machine guarantee the same amount of each candy in every bag?

No. The machine controls the combined total weight of all four candies.

The four vibratory feeders help create a relatively even product stream, but the system does not weigh or verify each candy separately. Some bag-to-bag variation should be expected.

If each bag must contain a fixed weight or percentage of every candy, use an independent mixture candy weighing and packing line.

2. Why does this mixed candy packing machine cost less?

The four candies are premixed before weighing, so the line only requires one 14-head multihead weigher and one shared discharge path.

A precise ratio-control system must keep the candies separate and weigh each product independently. This requires more weighing sections, controls and collection equipment.

3. What does the ±2 g accuracy refer to?

It refers to the total weight of the complete 907 g mixed-candy portion.

It does not mean that every candy type is controlled within ±2 g. For example, a finished bag may meet the total-weight tolerance while containing slightly more of one candy and less of another.

4. Can the four feeders be adjusted to change the mixture?

Yes. The feeding rate of each vibratory feeder can be adjusted to influence the average mixture entering the shared conveyor.

However, feeder adjustment is not the same as closed-loop ratio control. The machine does not verify whether every finished bag contains an exact 25% of each candy.

5. Will candies with different sizes remain evenly mixed?

That depends on the product.

Candies with large differences in piece weight, size, shape or surface friction may separate during conveying and weighing. Smaller or heavier pieces can move differently from larger or lighter candies.

Smartpack recommends testing all four actual candies together. We will check feeder stability, product separation and the composition of sample bags before confirming this solution.

6. Can the machine pack other target weights and bag sizes?

The system can be adapted for other requirements, but the result must be checked against hopper volume, target speed and the forming set of the VFFS machine.

For a larger portion, the same 5 L weigher may need more discharge cycles, which can reduce packing speed. A different bag width may also require another forming tube or VFFS model.

7. What information is needed before receiving a quotation?

Please provide:

• Photos and samples of all four candies
• Dimensions and average piece weight
• Required average proportion
• Acceptable variation between finished bags
• Target bag weight
• Finished bag width and length
• Packaging film information
• Required continuous speed
• Available ceiling height and floor space

These details allow Smartpack to determine whether the lower-cost premixing system is suitable or whether independent component weighing is required.
