Recently, customers have repeatedly asked us about a suitable large display unit for INDEC systems. They would like to be informed about the current degree of processing for the current batch as well as about error messages on a large-format display, which is visible from afar in the production hall. We are pleased to announce the availability of such a large display with an edge length of 63 x 14 cm for INDEC 300 model.

As you can see in the photos below, the counter number as well as the error messages are easily readable from a great distance. This makes it possible for the operating personnel to quickly take the necessary precautions to immediately eliminate the deficiencies in the filling process.

Thanks to the excellent, semi-automatic self-learning procedure for determining the sensor parameters (recipes) of the INDEC vacuum inspection systems, commissioning is possible without a KoCoS technician.

Ensuring the highest product quality is a primary and indispensable objective, especially in food production. The tightness of the product containers are an important role in this.

Leaks can cause the contents to leak out. But it is much more important that germs penetrate the container and spoil the product.

The INDEC vacuum testing systems monitor the tightness of containers fully automatically directly in the production process. A wide variety of containers such as bottles, jars and cans are checked for leaks without contact and defective containers are removed from the product flow.

Often, the necessary technician charges for commissioning, especially in Europe or overseas, are not in good proportion to the purchase price of an INDEC system. Sometimes these costs amount to another 30-40% of the purchase price for the equipment.

For this reason, it is very important to have good and meaningful documents such as the operating instructions and suitable videos. We have all those resources in good quality with the INDEC vacuum inspection system.

To make the start easier for the customer, we offer to send us some bottles and jars from his range. We already save predefined sensor parameter sets (recipes) in his ordered INDEC device ex works. If fine-tuning is still required, this can be completed between the end customer and us using modern communication media.

This has already been proven several times in the past, both in Germany with the company STANGL, in the EU with the French company ANDRESY and overseas with PRINCES TUNA in Mauritius. These screen shots illustrate the self-learning process.

The vacuum inspection systems of the INDEC series offer our customers a reliable solution for leak testing of jars, bottles and metal cans even under extreme operating conditions. The inspection takes place contact-free as a 100% in-line inspection directly in the production process. An optical sensor detects the vacuum-induced deformation of the lids. Even non-metallic container closures can be inspected. Containers with insufficient vacuum, crooked or missing lids are reliably detected and can be separated fully automatically from the product flow with an ejector. All components are made of stainless steel (1.4404), are resistant to cleaning agents and disinfectants and meet the requirements of protection class IP69K.

How do vibrations of the conveyor affect the reliability of INDEC systems?
We are often confronted by our customers with the question of whether the INDEC systems still function reliably when the conveyor belt is vibrating. This question can be answered with an unequivocal yes.
For this purpose, we would like to refer again to the measuring procedure and the mode of operation of all INDEC systems. The test procedure is based on the determination of the vacuum-induced deformation of the passing container closures. The tightness of the containers is assessed by comparison with a previously “Golden” sample. If a container to be inspected interrupts the light barrier under the sensor head, an infrared light beam is emitted by the sensor head and reflected by the lid of the container.  A sophisticated algorithm calculates the concave shape (yellow curve between the two red arrows, see the figure below measuring principle) of the deformed lid caused by the vacuum in the head space. Depending on the given boundary conditions, vacuum tests are possible from
50 µm deformation or from 150 mbar differential pressure in the headspace to the external pressure.

Avoid product recalls even before the goods leave production - with the reliable vacuum inspection systems from KoCoS.

With our INDEC range of vacuum inspection systems, food manufacturers have the assurance that HACCP (Hazard Analysis & Critical Control Points) principles are met.
KoCoS vacuum inspection systems are characterised by their superior detection sensitivity and automatic rejection of defective products in the food industry.

The ejector monitoring function checks whether the ejector has separated a container from the product flow that has been detected as bad. For this purpose, another light barrier is arranged parallel to the conveyor belt opposite the ejector. If the light barrier is not interrupted by the bad container within the adjustable delay after the ejector has been triggered, an error message is generated.
