The Benefits Of Modern Security Screening Equipment In The Food Industry

One of the most important steps in producing granular or powdered foods for sale and distribution is security screening at different vital points along the production line. Harmful pieces of debris or even unpredictable pieces of the substance can cause harm to consumers if they are packaged and placed into the supply chain. There have been many advances over the years dealing with security screening equipment for food applications. Modern screeners have several features that were not previously available to manufacturers.

No Vibrations

Some of the first pieces of screening equipment in the food industry were just long conveyor belts lined with woven screens. Food products moved along this line and then vibrated violently in order to extract larger clumps and foreign materials. The vibrations made the equipment prone to breakdowns and sometimes affected the quality of the final product as well as the amount of loss to airborne particles. The newest machines use rotating hoppers that do not create vibrations. Food is gradually sifted through screens until any particles above a certain size are removed. This safer and more efficient method uses far less power than the larger conveyor systems.

No Woven Mesh Screens

The screens that have been used in the past and that are still used in some facilities are made from woven metal. This means that thin wires are woven together to form a mesh. These woven screens make it easy for particles to become lodged in the mesh so that they are not removed from the hopper away from the product. New security screening equipment uses cut blanks that provide superior sifting capabilities. The result is a sifter that can sort through particles that are much smaller than what is possible with a woven mesh. The blanks also make it more difficult for pieces of debris to become lodged in an opening.

Conveyor systems are static. The sorting equipment must be kept in a single location. All products that need to be screened have to be moved to the location of the belt and then packed in that same area. Modern equipment does not have this limitation. Several models of the screening equipment available actually have casters on the base. This means that the unit can be rolled from one location to another where bulk feeding from a larger bin is easier. Portable units are easier to maintain, are more flexible and ultimately give a manufacturer more options when it comes to production efficiency.

Reduced Waste

Inefficient sifting machines cause a measurable amount of waste during production. The most modern security screening equipment uses a combination of technologies in order to reduce the amount of waste that is produced. This includes carefully calibrated hoppers and screens that sift without launching particles into the air. The convenience of a mobile piece of equipment also allows accurate positioning of the unit under a larger bin and over a receptacle. This stops the unintentional loss of product because of a misalignment that causes particles to miss the hopper or the packaging.
