SNB’s Blog

An integral part of the production line is the checkweigher. Having a checkweigher allows for compliance and the reduction of waste.

This blog intends to explore everything you need to know about checkweighing, including benefits and how they work.

 

How does a Checkweigher work?

In basic terms, a checkweigher looks at the products set weight and the set limits put in place. This set limit is predetermined so products aren’t under or over weight. For example the product running may be set at 300g meaning any products under 295g or above 305 would be rejected.

Depending on what type of checkweigher you have will depend on the range of features included. However, all checkweighers follow a similar principal, there is an infeed conveyor that is in place to settle the product and stop it from any movement. From there it is transported onto the weigh platform which weighs the product. The final belt is the outfeed belt (also known as the reject belt), if the product is under/overweight, it will be rejected into a bin or if the product is good, continue down the conveyor belt.

Checkweighers can be introduced at any point of the production process. It could be introduced near the start of the process to check the right amount of ingredients are within the products or at the end to check the final product before leaving for the supermarkets.

Benefits of using Checkweighers

Haven’t got a checkweigher already? There are a variety of benefits, here are just a few:

• Allows your factory to comply with any Codes of Practices
• Checkweighers consistently check the weight of your products allowing batches to be uniform
• Reduces the amount of giveaway on a product. This helps to keep production costs down
• Ensures that the product quality is consistent. Allowing products that don’t meet requirements (under weights and over weights) to be rejected
• Certain checkweighers come with data capture integrated into the system. This can help with tracking productivity levels and more

SNB Teleios Checkweigher
