In today’s food industry, vacuum technology is absolutely indispensable. Vacuum is not only important for hermetically sealing food products, but is also already used to sort products on conveyor belts and package or repackage goods quickly and efficiently.

In order to ensure that food products such as muffins, waffles, cookies, chocolates and even eggs can be handled with the necessary care, suction cups must be able to flexibly adapt to the surface characteristics of different foods. This helps to prevent leakage and also ensures that products can be handled quickly and reliably.

The food industry places exacting demands on the suction cup materials used in order to prevent contamination of the food products being handled. Schmalz suction cups for the food and beverage industry are made using FDA-compliant materials and also comply with EC Regulation No. 1935/2004.

Requirements for Vacuum Technology

No food contamination
The materials used must be FDA-compliant and also comply with EC Regulation No. 1935/2004. Schmalz suction cups are made of SI, SI-HD, and SI-MD, making them ideal for food handling.

Suction cups that can be detected by metal detectors
Suction cups made from SI-MD silicone, a material that can be detected by a metal detector, have been specially designed for contact with food products. SI-MD contains a small amount of metal oxide, which allows it to be detected by standard metal detectors. This means if a suction cup ends up in a tray, it can be quickly detected. This helps to prevent food contamination.

Adaptation to surface characteristics
Similar food products such as, for example, chocolates with or without toppings/decorations, often have very different shapes and surface textures. Suction cups used for food handling must be able to flexibly adapt to these different shapes and textures in order to prevent leakage while also securely gripping the products in question.

Picking up crumbs from dry food products
When it comes to the handling of dry food products, the gripper tends to suck up tiny crumbs. In order to prevent contamination of both the gripper and other food products, the crumbs must be disposed of appropriately. We also offer a solution for this challenge.

Cleaning the gripper
The suction cups must be cleaned regularly with suitable cleaning products in order to prevent contamination of the foods being handled.
