Throughout the food packaging industry, checkweigher machines are commonly used to weight product items as they pass through the production line. These machines allow manufacturers to have an overview of production data including production counts, batch tracking, and total weights, including approved or rejected weights. With that in mind, this article is going to serve as an overview as to why checkweigher machines are used and what they do.
What Are Checkweigher Machines Used For?
Checkweigher machines are capable of weighing items produced on a production line. These machines are often used to weight unwrapped foods prior to the packaging process. Common uses of checkweigher machines include:
- Determining underweight or overweight products
- Checking for missing components such as labels or instructions
- Verifies count by weight by checking for a missing carton, bottle, etc.
- Classifying products into weight zones
- Measuring and reporting production line efficiency
- Weighing before and after in order to check process performance
- Ensuring compliance with net contents law
- Fulfilling reporting standards
While checkweigher machines mainly weigh the products, this information can be used as an overview of the product batch.
Why Are Checkweigher Machines Used?
Overall, a checkweigher machine is used by packaging and processing companies in order to prevent unacceptable underweight or overweight products from being put out on the market. In doing this, these machines help manufacturers avoid having to go through a recall process or dealing with consumer complaints regarding underweight products. Furthermore, process safety is increased because abnormalities in food products will be caught by the checkweighers. This ensures that products that were possibly contaminated during the packaging process are further inspected to ensure consumer safety.
However, food inspection will work best when checkweighers, x-ray machines, and metal detectors are used together. This is because each inspection tool can detect different contaminants. For example, a food metal detector can detect ferrous, non ferrous, and stainless steel contaminants.
Additionally, checkweigher machines can significantly reduce overall material costs. By ensuring each product is at the appropriate weight, the machines reduce the risk of having to discard product if it was filled incorrectly. This also increases the process time by having weight inspection done quickly and efficiently, rather than it being done manually.
Checkweigher machines should be used in any food packaging facility to ensure each product is up to the standard weight. Manufacturers can benefit from these machines by reducing costs, increasing customer satisfaction, and increasing product quality.
