Degassing valves are commonly used in coffee packaging and help coffee roasters provide a fresher product. After roasting, it may take several weeks or months for the beans to reach the cup of a consumer. This delay in the supply chain makes your application important when shipping products to retail, coffee shops or end consumers. During the roasting process, coffee beans form volatile gases, such as carbon dioxide. By inserting a degassing valve to coffee bags, beans and ground coffee slowly release C02 without encountering oxygen.
Coffee roasters exploring upgraded packaging options or launching a new brand often incorporate degassing valves in their packaging. There are many benefits to your use in coffee packaging but they can also be used in the packaging of other consumer products including pet food.
Benefits of Degassing Valves in Coffee Packaging
Degassing valves maximize the freshness of your coffee beans on the store shelf. By allowing gas to escape but keeping oxygen out, your coffee beans remain fresh. Oxygen can cause coffee beans to become stale and impact the flavor of beans.
Degassing valves also increase your packaging efficiency. It could take weeks of rest for roasted beans to emit gases prior to packaging. By using a degassing valve on your coffee packaging, you can package beans right away without compromising your product. This allows you to ship more product without tying up production resources.
By releasing internal pressure buildup, your packaging can maintain its intended shape. When trapped inside packaging, gases can cause your coffee bags to inflate. This could cause bursting or leaking. Using a degassing valve ensures a shelf-stable product when you cannot control the supply chain.
Coffee Packaging Solutions by BW Integrated Systems
We produce a series of coffee valve applicator machines designed to integrate with your production line. Whether you are just starting out as a coffee roaster or, are a recognized brand, we can help. BW Integrated Systems is a worldwide provider of flexible packaging solutions. We offer a variety of solutions to improve your coffee packaging.
The PRV 204 Series Applicators are designed specifically for the application of “outside” degassing valves. Using a valve applicator maintains product quality and aroma. It also relieves pressure in airtight packaging and protects your product from oxygen. Our degassing valve applicator is excellent for volume coffee roasters because it can run 24/7. This machinery can easily be integrated with the rest of your high-production product line without slowing it down.
How Are Degassing Valves Applied?
Many consumers do not notice degassing valves when they purchase their coffee. Our PRV 204 Series applies these valves to the outside of the coffee bag. This simplifies the application process, and eliminates an extra step required when applying valves inside of the bag.
The valve application process is controlled by an integrated microprocessor. This process includes oil insertion into the valve, punching a hole into the container, and placing the valve over the hole. With continuous operation our valve applicators can apply up to 300 valves per minute.
PRV 204 Series Degassing Valve Applicator Machines
Depending on the size of your production, you may have different needs. At BW Integrated Systems we offer two model options under the PRV 204 line.
These products seamlessly integrate with vertical and horizontal form-fill-seal machines and bag making machines.
The PRV-i 204 model is intended for intermittent motion, capable of applying 110 valves per-minute. For larger roasters, the PRV-c 204 model provides continuous motion integrated into your flexible packaging line.
These top performing coffee valve applicators offer the flexibility to run all makes of currently available valves. They come with oil injection modules but can also run pre-oiled valves.
