Tubular Fruit Preheater for Juice and Puree Processing
The tubular fruit preheater heats fruit pulp or juice before downstream processing. It can support enzyme inactivation, tissue softening and thermal pretreatment when the temperature and residence time are matched to the product. Typical applications include crushed apple and tomato puree processing.
How the Tubular Fruit Preheater Works
Product flows through the inner tube while the heating medium circulates around it in the outer tube. Heat transfers across the tube wall without direct contact between the product and the heating medium. The recirculating water circuit can recover heat, depending on the final line design and operating conditions.
Tubular Fruit Preheater Features
- The specified outlet temperature range is 55–95°C; the required setpoint depends on the fruit, viscosity and process target.
- Steam or heated water can supply heat according to the selected configuration.
- The listed product-contact material is SUS304 stainless steel; confirm the final material schedule for the ordered unit.
- The tube-in-tube layout and polished product path are designed to support heat transfer and cleaning.
- Automatic temperature control, alarms and CIP functions should be confirmed against the final control specification.
- The supplier describes heat recovery of up to 90%; actual recovery depends on the heat balance of the complete line.
