Uhde High Pressure Technologies (UHPT), a company of thyssenkrupp AG, and system provider in the sector of high-pressure technology, has been developing, designing and manufacturing components (containers, valves, pumps, fittings and other items) and complete systems (turnkey systems) for more than 80 years. These systems are used mainly in the food and pharmaceutical industry. The delivery program for the food industry also includes systems, which can be used to preserve the foodstuffs gently through high-pressure treatment. The advantage of this technology is that the products can be treated in their final packaging so that contaminations from the handling and packaging processes are eliminated effectively. Foodstuff treated in this manner retains its vitamins, aromas and flavourings and even thermally susceptible products can be handled as the process is conducted at cool temperatures. From the customer perspective, this type of treatment is therefore a safe, sustainable and biological process as the shelf life is extended and preservatives can be dispensed with. In addition to industrial production systems with a capacity of up to 700 litres and an operating pressure of 6,000 bar, UHPT also manufactures special systems for sterilisation. These special systems work with an increased pressure of 7,000 bar and temperatures of up to 121°C. Test and laboratory systems round off the portfolio UHPT offers.
In addition to the systems for high-pressure pasteurisation, UHPT has specialized in customized high-pressure systems, which obtain extracts from organic material (e.g. flavourings and special ingredients) with the help of supercritical gases (e.g. carbon dioxide). Starting materials can be, for example, spices, herbs but also algae. Coffee or tea can be decaffeinated, spice extracts can be manufactured or special powders for the pharmaceutical industry, etc. can be implemented with the help of these extraction systems from UHPT.
