Ensuring the highest product quality is a priority and indispensable goal, especially in the production of food. The tightness of the product container plays an important role.

Leaks can cause their contents to escape to the outside. It is much more important, however, that germs penetrate the container and spoil the products as a result.

The INDEC vacuum testing systems automatically monitor the tightness of containers 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.

Sometimes, however, small food manufacturers have limited financial budgets to invest in a new complete system for checking closures. For this reason we have developed the price-sensitive basic system INDEC VD 80 and launched it on the market now. The INDEC VD 80 only contains the three core components display unit, connection unit and the sensor head. The required frame components for holding and aligning the sensor head and for holding the display unit and the connection unit often exist from old sensors systems that have been used up to now, which can no longer be repaired economically after more than 15 years of usage. With little effort, those can be modified to accommodate the new core components. The INDEC VD 80 does not differ in any way from the INDEC VD 100 in terms of functionality and reliability.

With our INDEC series vacuum inspection systems, food manufacturers have the certainty that the HACCP principles (Hazard Analysis & Critical Control Points) are fulfilled.

In the past, we have been asked several times by our customers whether INDEC VD 100 inspection system can provide a signal to the higher-level machine control which signals that the measuring system is ready for operation. This electrical switching contact for signalling the switch-on state of INDEC VD 100 system is now also available as a retrofit option for already supplied INDEC systems.

After pressing the main switch on the front panel, the INDEC VD 100 vacuum device is switched on. A visual check of the device by the user ensures that the vacuum tester is ready for operation, the relevant recipe has been loaded and all distances for the sensor head and the light barrier have been set correctly. The readiness for operation of the INDEC VD 100 is signalled to the higher-level machine control system by an electrical switching contact.

An additional optical coupler, which is mounted on the terminal strip as shown below, is used to exclude any interference between the machine controls.

Once the connection has been made according to the updated connection diagram, this ready signal is then permanently available in the customer's higher-level machine control. The filling line is only started after an internal, positive acknowledgement in the control system. This link ensures that all bottles and jars produced are subjected to a closure check.

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 VD 400 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.
