UHT heat treatment through concentric tubes, used where product is too thick or too pulpy for a plate pack.
When product carries fibre, pulp or fruit pieces, a plate gap blocks and a tube does not. Tubular sterilisers pass product through concentric tubes with the heating medium on the outside, giving a wider flow channel and longer runs between cleans. They reach UHT conditions for products destined for aseptic filling. This category covers tube in tube and tubular UHT designs. We select tube diameter and pass arrangement against your product's viscosity and particle size, and match the unit to the aseptic filler that follows it.

View Category →Pulp content and viscosity decide it. Send a product description and we will advise which design suits and why.
It depends on capacity and control scope and is confirmed with the quotation.
Yes, and we recommend quoting both together so the sterile connection is engineered as one system.
Manuals and drawings are supplied in English. Any certification required for your market is confirmed on request.
Usually yes within a viscosity range. List the recipes and we will confirm the span one unit can cover.
Send the capacity duty or drawing you need for tubular sterilizers and we will match it to the factory that builds it and quote it in writing.
