Pro Seal - Preheater

Applications & Use Cases

• Preheating liquid or semi-liquid food products before further processing like pasteurisation or sterilisation.
• Increasing the temperature of ingredients to improve mixing efficiency or reduce cooking times.
• Tempering chocolate or other confectionery ingredients to achieve desired consistency and finish.
• Warming up viscous products to facilitate pumping and transfer within a processing line.
• Recovering heat from waste streams to improve overall energy efficiency in a food plant.

Typical Specifications

Typical capacity

For this class of equipment, capacities commonly range from 500 to 5,000 litres per hour, depending on product viscosity and desired temperature differential.

Power supply

Units of this type typically operate on a 3-phase electrical supply, commonly 400V, 50Hz, with power requirements varying based on heating method and capacity.

Heating method

Preheaters commonly utilise steam, hot water, or electrical elements as the heating medium, often employing plate or tubular heat exchanger designs.

Temperature range

Typically designed to achieve product temperatures up to 90-95°C, suitable for a wide range of preheating applications.

Materials of construction

Contact parts are commonly manufactured from food-grade stainless steel (e.g., 304 or 316) for hygiene and corrosion resistance.

Footprint

The footprint for a preheater of this model class is typically compact, designed for integration into existing processing lines, often requiring approximately 1-2 square metres of floor space.
