PROCESS AND UHT INSTALLATION FOR TREATING A PRODUCT CONTAINING ADDITIONAL INGREDIENTS IN PIECE FORM UNDER ASEPTIC CONDITIONS

The invention relates to a process for treating a product containing additional ingredients in piece form, such as for example pieces of fruit, the flesh of fruit in pieces, fibrous or papillary formations filled with fruit fluid, or generally particles of low resistance to mechanical and/or flow-me...

Beschreibung
Zusammenfassung:	The invention relates to a process for treating a product containing additional ingredients in piece form, such as for example pieces of fruit, the flesh of fruit in pieces, fibrous or papillary formations filled with fruit fluid, or generally particles of low resistance to mechanical and/or flow-mechanical stresses, or a mixed product consisting of a carrier liquid and such additional ingredients in piece form, under aseptic conditions according to claim 1 and to a UHT installation for carrying out the process according to claim 13. The object of the present invention is to provide a process in this respect and a UHT installation in this respect that ensure more gentle treatment than previously achieved in the prior art. One way in which this is achieved in process engineering terms is that, in an operating phase (B) following a start-up phase (A) and a transitional phase (U), in which delivery by a delivery device (30) designed as a pump takes place, the delivery velocity (c) is produced exclusively and sustainably by a first pressure (p1), to be provided at a first location (I) in the product or mixed product (M), this pressure originally being generated by a controllable driving pressure (p(DM)) of the pneumatic pressure medium (DM) that is dependent on the first pressure (p1).
