How to Choose a Multihead Weigher for Pickles, Fresh Meat and Sticky Foods?

Weighing pickles, fresh meat, mustard, capers, and other sticky foods can be challenging for standard weighing equipment. Choosing the right multihead weigher for sticky products requires more than looking at the number of weighing heads or maximum speed. Product characteristics, hopper design, cleaning requirements, target weight, and production capacity should all be considered.

This guide explains the key factors to consider when choosing a multihead weigher for pickles, fresh meat, and other difficult-to-handle foods.

Why Are Sticky Foods Difficult to Weigh?

Unlike free-flowing products such as grains or dry snacks, sticky foods do not always move smoothly through a weighing system.

Common problems include:

• Product sticking to hopper surfaces
• Residual material affecting subsequent weighing cycles
• Uneven product distribution
• Difficult and time-consuming cleaning
• Inconsistent weighing results
• Reduced production speed

For these applications, the hopper surface and discharge design are particularly important.

1. Choose the Right Hopper Surface

The hopper is one of the most important components when weighing sticky foods.

A conventional smooth hopper may allow products such as pickles, meat pieces, or marinated vegetables to adhere to the surface. This can cause product residue and affect the accuracy of subsequent weighing cycles.

A dimple hopper uses a textured surface designed to reduce product adhesion. When combined with a scraper mechanism, it can also help remove residual material from the hopper.

For sticky and wet products, a dimple or scraper hopper can therefore be more suitable than a standard smooth hopper.

2. Consider the Product Characteristics

Not all sticky foods behave in the same way.

Before choosing a multihead weigher, consider:

• Moisture content
• Viscosity
• Stickiness
• Product size
• Product shape
• Oil, sauce, or brine content
• Whether the product tends to clump

For example, pickles may contain brine, while fresh meat can contain moisture and fat. Mustard has a much higher viscosity than solid food pieces.

The weighing system should be tested with the actual product whenever possible.

3. Check the Required Weighing Range

The target package weight is another important consideration.

A multihead weigher should provide a suitable weighing range for your products and package sizes. Small retail packages may require only a few grams, while larger foodservice packages may require several hundred grams or more.

For example, UUPAC's Dimple 14 Head Computer Combination Weigher has a weighing range of approximately 5–600g, making it suitable for many small and medium-sized food packages.

4. Look at Production Speed

Production speed should match your actual packaging requirements.

A machine with a high theoretical speed is not necessarily the best choice if the product is difficult to handle. Sticky products may require different operating conditions from dry, free-flowing products.

The actual output depends on factors such as:

• Product characteristics
• Target weight
• Hopper configuration
• Feeding method
• Packaging machine speed

UUPAC's Dimple 14 Head Weigher can reach speeds of up to approximately 60 packs per minute, depending on the application.

5. Pay Attention to Cleaning and Hygiene

Cleaning is particularly important when processing meat, pickles, sauces, and other wet foods.

A suitable multihead weigher for sticky food should be designed with cleaning and hygiene in mind.

Important factors include:

• Waterproof protection
• Easy-access hoppers
• Simple disassembly
• Residue removal
• Food-contact material selection

For example, the UUPAC Dimple 14 Head Weigher features an IP65-rated design, helping protect the equipment against water and dust during production and cleaning operations.

6. Consider Accuracy and Product Giveaway

Overfilling every package by a small amount can result in significant product loss over time, especially when processing high-value ingredients such as meat or imported food products.

A combination weigher uses multiple weighing heads to calculate suitable weight combinations and achieve the target weight.

The UUPAC Dimple 14 Head Weigher is designed for high-precision weighing and can achieve accuracy of up to approximately ±0.1 g, depending on the product and operating conditions.

Which Sticky Foods Can Be Weighed With a Dimple Multihead Weigher?

Dimple multihead weighers are commonly considered for products that are sticky, wet, irregular, or difficult to discharge.

Typical applications include:

• Pickles
• Capers
• Fresh meat pieces
• Mustard
• Marinated vegetables
• Wet fruits and vegetables
• Other irregular food products

However, product testing is recommended because moisture, viscosity, particle size, and stickiness can vary significantly between products.

Why Choose a Dimple 14 Head Weigher?

For food manufacturers handling difficult products, a Dimple 14 Head Weigher combines multiple features designed for sticky-product applications.

Its key features include:

• 14 weighing heads
• Dimple scraper hoppers
• 1.3 L hopper capacity
• 5–600 g weighing range
• Up to approximately 60 packs/minute
• IP65 protection
• Touch-screen control
• PLC-based control system

The dimple hopper and scraper mechanism are particularly important because they address one of the main challenges of sticky food weighing: product residue.

Conclusion

Choosing a multihead weigher for pickles, fresh meat, and sticky foods requires careful consideration of product characteristics, hopper design, weighing range, production speed, cleaning requirements, and accuracy.

For free-flowing products, a conventional multihead weigher may be sufficient. For sticky or wet foods, a dimple multihead weigher with scraper hoppers can provide a more suitable solution by helping reduce product adhesion and improve material discharge.

Before purchasing, it is recommended to test your actual product and confirm the required weighing range, speed, accuracy, and cleaning requirements. This ensures that the selected weighing machine matches your production line rather than simply choosing equipment based on its specifications.
