Problems solved by technology

One problem with this type of packaging is that the goods have a limited shelf life, which for many products is only several days to a week.
Removing air during packaging is a problem in weighing and filling machines, which automate the packaging process.
The space available for gassing operations is often limited in machines such as combination weighers, which employ weighing buckets and timing hoppers to meter the product and fill packages making it difficult to remove unwanted air.
In packaging assemblies that use hoppers or collating funnels to direct the material to be packaged, the material continues to pull in unwanted air as it moves down the hopper or funnel.
Furthermore, the speed at which packages are filled limits the ability to reduce the amount of air in the product to the desired level prior to sealing.

Embodiment Construction

[0020]FIG. 1 is an illustrative packaging system 10 for a gassing apparatus made in accordance with the present invention. The packaging system 10 includes a plurality of weighing buckets 20, a hopper assembly 30, a filling tube 40, a packaging assembly 50 and a gassing controller 80. The packaging system 10 further includes a gassing assembly, described in more detail below.

[0021] The hopper assembly 30 includes a hopper 32 for receiving product from at least one of the plurality of weighing buckets 20 and bracket 34 (FIG. 2). Hopper 32 comprises a funnel or cone shaped receptacle as are well known in the art. Hopper 32 tapers towards filling tube 40. Filling tube 40 includes a funnel shaped upper end 42 for receiving product from hopper 32 and a lower end 44 where product exits into a formed package (not shown). The packaging assembly 50 includes film rollers 52, product stager 54 and seal jaw 56. Packaging assembly 50 may include other components for forming and filling a packag...

Abstract

A focal point gassing device or system including a gas supply tube operably connected to supply gas to a focal point gassing head and a screen attached to the lance head, wherein the screen provides high velocity laminarized and directed flow gas to product moving through a vertical form/fill/seal packaging system. The vertical packaging system includes a focal point gassing device and a gassing lance to provide gas to product as it moves from a packaging hopper through a filling tube and into the package. The packaging system includes a gassing control system monitor and adjust the flow of gas to the gassing apparatus.

Description

RELATED APPLICATIONS [0001] The present application claims priority to U.S. Provisional Application No. 60 / 658,750 filed Mar. 3, 2005, titled “Device and System for Modified Atmosphere Packaging”, the entirety of which is incorporated by reference.FIELD OF THE INVENTION [0002] The invention relates to apparatus for exposing product to a controlled and / or modified atmosphere environment, and more particularly to a gassing apparatus for delivering gasses and mixtures into packages. BACKGROUND OF THE INVENTION [0003] Various products, including food products and any other products having an adverse reaction to air, are packaged in a modified atmosphere and / or a controlled environment. Various attempts have been made to efficiently package these products in modified atmosphere and / or controlled environments using vacuum and / or controlled environments. [0004] Various food products, including nuts, snacks, cheese, meats, fruits, and vegetables, are packaged under regular atmospheric condi...
