The homogeniser’s innovative pump mode offers some significant advantages over conventional systems. It allows damage-free mixing of chunky goods without using an additional pump with piping. It also replaces a costly discharge and recirculation pump, since it additionally ensures that shear-sensitive products can be discharged quickly.

Manufacture of Relishes

After the recipe started at the touch panel of the vacuum processing plant, the process starts by feeding water, fresh tomato and chopped onions, where the required quantities are added automatically. The operator adds the required spices, herbs and vinegar manually to the hoppers for small quantities and acknowledges the manual step in the recipe control. Afterwards, automatic infeed and homogenisation starts.

The heating process for pasteurisation starts along with homogenisation. The homogeniser runs in pump mode throughout the entire heating process in order to heat the chunks of goods without destroying them. It is possible to take samples during or before discharge.

Process Control

The new vacuum processing line has been equipped with zoamatic smart controls, based on a 10” touch panel from Siemens. The entire process is clearly visualised and can be manually operated. A program editor allows the customer to save up to 300 different recipes and produce in automatic operation.

Conclusion: The customer was particularly impressed by the fact that, despite the very considerable distance between Neuenburg and the customer, trials in Neuenburg with the original product were conducted in the well-equipped test centre with adjacent laboratory. It was possible to transfer the results from laboratory scale to actual production scale. The customer has obtained a plant that has been entirely customised for his processes. He is enthusiastic about the results and delighted that they were able to convince their major customer with innovative products. Production results from the plant have made a crucial contribution towards acquiring other major customers for these innovative products.
