Quality control systems for canning lines

Quality control is a required process for all production lines. The quality control systems for canning lines that we have at E2M COUTH are essential, given how vulnerable this kind of product is. The container can lose quality or pose risks when it reaches the end consumer.

Operation of quality control systems for canning lines is essential to guarantee that the tinned products meet quality and food safety standards.

What we will highlight in this section is the inspection and quality control process on the production. These are the processes each one of the products will go through:

  • Sensors and control devices: Sensors and control devices are installed along the production line to supervise different aspects of the tinned products. This can include artificial vision sensors for visual inspection, scales for weight control, temperature sensors to verify the pasteurisation process, and more.
  • Real-time inspection: As the products go down the production line, the quality control systems conduct inspections in real time. Each product undergoes multiple verification, such as detection of possible defects in the container, weight measurement, temperature verification, and more, if necessary.
  • Comparison with quality standards: The data collected during inspections are instantaneously compared to pre-defined quality standards. If a product does not meet standards, it is identified as non-compliant and registered.
  • Corrective actions: If a non-compliant product is detected, quality control systems can activate rejection mechanisms to remove the defective product from the production line. Additionally, alerts and notifications are generated so that staff can take corrective measures if necessary.

These quality control systems for canning lines are present in each process. For this reason, we are going to highlight each one of them.

Stage 1: Tin filling

Filling the tins is one of the first crucial stages in production. In this phase, the product is placed in specific containers, such as tins or bottles, and it is essential to guarantee precision and consistency in each container. Quality control systems for canning lines play a vital role here in verifying:

  • Fill volume: It measures and verifies that each container has the right amount of product. Incorrect fill can lead to loss of product or quality issues.
  • Sealing and closing: It ensures that the closure and seal are leak-tight, avoiding contamination and oxidation.

To this end, these systems have technologies for quality control during the fill process. Moreover, the artificial vision machines can detect defects in the containers and ensure that the closure is correct.

Stage 2: Marking and labelling

Marking and labelling tin containers is critical for traceability and consumer information. The quality control systems in this stage are focused on:

  • Correct printing: It verifies that the printed information is legible and precise, including expiry dates, batch numbers, and bar codes.
  • Label positioning: This system guarantees that the labels are placed correctly, with no overlapping or air bubbles.

In terms of the technology in charge of this process, at E2M COUTH, we have artificial vision systems that are perfect for verifying and controlling the quality of the mark and labelling on canning lines.

Stage 3: Closing and sealing

This is another one of the key processes that you must control with quality control systems for canning lines. The defective closure of a container could put the product’s safety at risk. During this stage, these quality control systems take care of:

  • Leak-tight sealing: The system checks that there are no liquid or gas leaks in the containers, which could lead to their contamination.
  • Checking that caps are intact: It also ensures that the caps are in perfect condition, without denting or deformations.

For containers to correctly go through this stage, it is best to have cap inspection machines and vision systems to take care of finding all problems and anomalies in products.

Stage 4: Pasteurisation

Pasteurisation is a heat treatment process that eliminates pathogenic microorganisms and maintains product quality. The systems in charge of quality control in this stage ensure:

  • Temperature and treatment time: The system ensures that the required temperatures are reached and maintained for as long as necessary to achieve effective pasteurisation.
  • Controlled cooling: After the pasteurisation process, the system ensures that the products are correctly cooled to avoid the spread of heat-resistant bacteria.

The systems in charge of controlling these aspects are thermometers and temperature inspectors in the pasteurisation process. What is more, the data log system provides detailed tracking of the entire process.4

Quality control systems for canning lines play an essential role in this industry, with great, significant benefits. These systems guarantee that the products meet the highest quality standards in each production stage, from filling to pasteurisation. As follows, we provide details on the key benefits of quality control systems for canning lines:

Product quality guarantee

The clearest benefit is the quality guarantee for the end product. Quality control systems detect and correct possible problems with quality in each batch of tins, which guarantees that the product will reach consumers in the best condition.

Food safety

Quality control systems for canning lines help to prevent contamination and the spread of pathogenic microorganisms. This is essential to guarantee food safety and to protect the health of consumers.

Compliance with regulations and standards

The tinned food industry is subject to strict regulations and quality standards. Quality control systems for canning lines ensure compliance with these standards, which prevents possible legal sanctions and protects the company’s reputation.

Reduced product waste

Detecting and correcting quality problems in time reduces the number of defective products that reach the market. This reduces waste of raw materials and resources.

Increased production efficiency

Quality control systems for production lines identify and verify inefficiencies in the production process. This can lead to more efficient and profitable production.

Improved traceability

Tracking and traceability are essential in the canning industry. Quality control systems for canning lines help to log and document each stage of the production process, which facilitates identification and resolution of problems.

Improved brand reputation

Consistency in product quality improves the brand’s reputation with consumers. Customers trust products with constant quality, and they are more likely to keep purchasing them.

Reduced returns and complaints

By guaranteeing product quality, you reduce consumer returns and complaints. This saves time and costs associated with managing after-sales issues.

Improved competitiveness

Companies that can constantly offer high-quality products have a competitive advantage on the market. This can translate to increased sales and higher market share.

Flexibility and adaptability

Quality control systems for canning lines allow companies to identify trends and changes in product quality over time. This facilitates adaptation and decision-making based on data.

At E2M COUTH, we have different solutions for production quality control, in this case tins. Using them comprehensively improves the production process as a whole.

These are the devices we have available at E2M COUTH:

Orientation systems

During the production line, one of the most important processes for proper filling or sealing of products are orientation systems. These systems are in charge of putting products in the correct position and can rotate containers 90, 180, or 270 degrees. This kind of system can adapt to different shapes and sizes.

Inspection systems

When products go down a production line, they must be inspected to ensure that they are in perfect condition. This kind of system is perfect for inspecting labels, product levels, inspecting caps, inspecting glass bottles, and other jobs.

This kind of system is highly useful for product quality control and safety, especially during labelling, filling, sealing, and other processes.

Rejection systems

Defective products or products with some sort of issue that should keep them from the customer’s hands can appear on any production line. This is why the rejection systems we have at E2M COUTH can analyse and take articles with problems off a production line.

Within rejection systems, at E2M, you can find two kinds: impact rejection systems, perfect for products that are not delicate. This system removes the article with a blow, taking it off the production line. We also have gentle diversion rejection systems, perfect for fragile products. This system moves the defective product, creating a parallel line, to analyse whether it can be recovered.

Marker systems

Another system you can find at E2M COUTH is a product marking system. This is perfect for finding any product. We have a marking system that works with a laser. It can mark and encode a wide variety of containers so you can find them quickly and easily.
