Description

This application claims priority to U.S. Provisional Application No. 63/237,417 filed Aug. 26, 2021, the entirety of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

Food production areas must be designed to maintain sanitary conditions and for ease of cleaning and maintenance. Food processing and production require extra precautions compared to other manufacturing environments to prevent contaminants. Appropriate wall and floor surfaces must be chosen to facilitate sanitary conditions. In addition, appropriate barriers may be used to isolate products and prevent contaminants in the products.

Also, in areas where production workers are in close contact with one another, there is a desire and a need to separate people as they flow in opposite directions, perform work in areas where tasks must be separated, wear different garments from each other as specified by specific product contact, as well as many other reasons. Such separation of production workers may also prevent cross-contamination of food products as well as the spread of illness between production workers.

To separate production workers, manufacturers may spread out processes or tasks, or may erect barriers between workers. Spreading out processes or tasks requires a larger footprint for manufacturing, longer conveyors and other equipment, and is not usually an economically viable solution. Many manufacturers opt to erect barriers instead. Specific guidelines require such barriers used to create the separation between personnel to be washed and sanitized frequently.

Such barriers may be embodied as panels. Barriers must be easy to sanitize, and are preferably transparent or translucent so that production workers may see the products and processes before and after their stations.

There are several options for materials for such barriers, including: plastic, plexiglass, glass, and stainless steel, each having benefits and drawbacks. Plastic and plexiglass are lightweight, flexible, and shatter-resistant. However, plastic surfaces degrade over time, which creates space for bacterial and other contaminants, and would need to be frequently replaced to maintain the integrity of the panels. Glass is heavy and easily breaks during removal for cleaning. Stainless steel does not have the translucent qualities desirable in manufacturing to see the products and processes before and after each station.

Panels in food production must be cleaned frequently. One concern in food processing and production is space and connection or contact points where contaminants may become trapped and are difficult to clean. It is desirable for panel assemblies to have as few contact points as possible to minimize contamination. It is also beneficial for panel assemblies to be easy to disassemble for panel replacement.

Various panels and panel holders have been manufactured in the past. But none confront the issue of harboring bacteria in design. Existing products hold panels vertically with the use of a gripping device on various edges of the panel. The process of gripping the panel between two surfaces generates an area which harbors bacteria.

SUMMARY OF THE INVENTION

The barrier disclosed herein includes a panel designed to minimize bacteria and contaminants, separate workers, and be properly maintained easily.
