Key Components of an Automatic Dosing System

1. Dosing Mechanisms for Solid and Semi-Liquid Ingredients

Precise dosing of solid and semi-liquid ingredients ensures consistent portion sizes, maintains product quality, and prevents waste. Different dosing mechanisms are required based on ingredient type to achieve accuracy and efficiency.

For solid ingredients like pasta, rice, and vegetables, volumetric dosing systems are commonly used. These systems dispense a fixed volume of product, ensuring uniform portions while maintaining ingredient integrity. 

They are ideal for fragile ingredients that could break under excessive pressure.

Semi-liquid ingredients, such as sauces, dressings, and purees, require piston or pump-based dosing. These systems control the amount dispensed by adjusting stroke length or pump speed, ensuring smooth and even distribution. 

Proper flow control is important to prevent clogging and maintain consistent portioning, especially for viscous or particulate-laden mixtures.

Some ready meals contain multiple components that have to be dosed simultaneously. Multi-head dosing systems allow different ingredients to be dispensed in precise amounts at the same time, improving production speed and consistency. 

These systems also reduce the risk of ingredient separation, ensuring a uniform final product.

Accurate dosing mechanisms prevent ingredient waste while maintaining product quality and consistency.

2. PLC-Based Control Systems for Accuracy and Efficiency

PLC (Programmable Logic Controller) systems form the automation backbone of modern dosing systems, ensuring that every portion meets strict accuracy standards. These controllers regulate multiple dosing parameters, including portioning speed, weight, and ingredient ratios, to maintain consistency across production runs.

A PLC system continuously monitors and adjusts dosing operations in real-time. Sensors detect inconsistencies in ingredient flow, weight deviations, or improper portioning and send feedback to the PLC. The system then makes immediate corrections to prevent waste and maintain uniform quality. This closed-loop control minimizes errors and reduces manual intervention.

Key features of PLC-controlled dosing systems include:

• Real-time monitoring – Operators can track ingredient dispensing, identify issues, and make adjustments instantly.

• Pre-programmed recipe storage – The system allows quick switching between meal variations, reducing downtime.

• Automated feedback loops – Sensors detect errors and trigger corrections without stopping production.

PLC systems ensure dosing precision by continuously adjusting parameters based on real-time data.

3. Integration with Tray Handling and Packaging Lines

Automatic dosing systems have to integrate with tray handling and packaging lines to maintain efficiency. A well-coordinated system ensures accurate ingredient placement, prevents misalignment, and keeps the production line running without interruptions.

To achieve this, dosing systems are designed to work directly with tray handling equipment. They dispense ingredients into trays that are already positioned in the correct location, reducing the risk of spills or uneven distribution. 

Synchronization between dosing and tray movement is important to prevent delays or misaligned portions. If trays do not align properly, ingredients might be dispensed inaccurately, leading to waste or inconsistent product quality.

Flexibility is another important factor. Dosing systems have to accommodate trays made from different materials, such as plastic, aluminum, or cardboard. They also need to handle various tray sizes without requiring frequent manual adjustments. This adaptability allows for the production of different meal types without extensive downtime.

Beyond dosing, integration extends to sealing and labeling units. 

Once ingredients are placed, trays move seamlessly to the sealing stage, where they are covered to maintain freshness. Labeling systems then apply product information, ensuring compliance with regulatory requirements while improving traceability.

When upgrading equipment, manufacturers often need reassurance that new dosing systems will work with their existing production line. Compatibility between old and new machinery is key to maintaining efficiency. 

Modern dosing systems use standardized communication protocols to exchange real-time production data, synchronize tray handling with dosing, and adjust portioning based on system feedback, allowing seamless integration without disrupting operations.

Seamless integration between dosing, tray handling, and packaging ensures consistent quality and operational efficiency.

4. Hygienic Design and Compliance with Food Safety Standards

Automatic dosing systems have to meet strict hygiene requirements, as they handle ingredients that go directly into the final product. Poor sanitation can lead to bacterial buildup, compromising both product quality and consumer health.

To ensure cleanliness and durability, dosing components are typically made from high-quality stainless steel. This material resists corrosion and allows for thorough cleaning, reducing the risk of contamination. 

Many systems also feature tool-free disassembly, enabling quick sanitation between production runs. Operators can easily remove and clean components without specialized equipment, minimizing downtime and maintaining consistent hygiene standards.

Compliance with industry regulations is another important factor. Automatic dosing systems should meet standards such as HACCP and ISO 22000, which outline requirements for food safety management. 

Many systems incorporate self-cleaning mechanisms to simplify maintenance. Features like automated flushing and CIP (clean-in-place) technology remove residue without manual intervention. 

Additionally, minimal contact design reduces the number of surfaces that come into direct contact with ingredients, further lowering the risk of bacterial growth. 

Machine structures must also be designed to eliminate holes, gaps, or other areas—such as tire covers—where spills can collect and bacteria may develop. These design improvements further enhance food safety by reducing contamination risks in hard-to-clean areas.

Hygienic design in dosing systems prevents contamination and ensures compliance with food safety regulations.
