Tubular pasteurizer and sterilizer SANIFLUID+

for the food industryfor the beverage industryin-line

Overview
SANIFLUID+ is a tube‑type continuous pasteuriser/steriliser using direct radio‑frequency (RF) dielectric heating. It is engineered for liquid and pumpable products, including formulations with suspended particulates, to deliver high throughput with minimal thermal impact on sensory and physico‑chemical properties.

Key features

• Continuous RF direct heating inside food‑grade RF‑transparent tubes positioned between sized electrodes.
• Applicable to liquids and pumpable (fluidised) products, including products with suspended solids.
• Rapid and controllable heating rates with precise temperature control for pasteurisation or sterilisation.

Performance and typical use
Installed lines commonly report reference throughputs around 2,000 kg/h, depending on product and configuration. Heating rates depend on viscosity and particulates: approximately 1–2 °C/s for highly viscous particulate‑laden products and up to 50–100 °C/s for low‑viscosity clear liquids. Temperature set points can be reached and maintained with an accuracy of ±0.5 °C.

How it works
The product is continuously pumped through one or more food‑grade RF‑transparent tubes sized to the product. Tubes are placed between electrodes designed for the tube diameter and product characteristics. The RF field heats the product directly via dielectric losses; field intensity and heating rate are regulated by a variable‑capacity coupling circuit to achieve required pasteurisation or sterilisation with minimal thermal damage.

Supply options
SANIFLUID+ is available as a stand‑alone module for integration into existing lines or as a complete processing technology including product feeding, cooling, aseptic filling, CIP and pigging systems and other ancillaries per customer requirements.

Benefits

• Minimal thermal treatment, better quality, safer product — Rapid, uniform heating (including within suspended particulates) reduces under‑ or over‑processing; microbial inactivation is achieved at lower temperatures and shorter times than conventional methods, preserving sensory, chemical and physical properties.
• Fast and flexible process — Instant heat input, accurate control and high operational flexibility; compatible with CIP and pigging for in‑line product change and recovery; suitable for small and medium batches; sterility can be maintained in stand‑by.
• Floor‑space saving modular system — Multiple units can be installed in‑line to scale capacity while keeping a compact footprint.
• Minimum maintenance required — Non‑contact heating avoids crusting/fouling, simplifies cleaning and reduces maintenance costs.
