China Juice Processing Heat Exchanger Manufacturer Providing Heat Transfer Solutions For Juice Manufacturing Applications

A juice processing heat exchanger heats and cools juice during pasteurization and aseptic filling, where pulp, sugar and heat sensitivity make the design different from water-like fluids.

This article covers the duties, the hygiene and cleanability needs, and how to specify a juice exchanger that protects both safety and flavour.

Juice is pre-heated, pasteurized at holding temperature, then flash-cooled before filling. A regenerative section recovers heat from the hot pasteurized juice to warm the incoming stream.

Concentrate and pulp streams add viscosity and fouling, shifting the design toward robust, cleanable equipment.

Pasteurization uses a plate pack with a holding tube; aseptic cooling follows so the product reaches the filler safely. Regeneration reduces the utility load substantially.

• Regeneration:  recovers heat from hot juice to pre-warm incoming juice.
• Holding:  maintains pasteurization temperature for the required time.
• Aseptic cooling:  brings product to filler temperature under sterile path.

Wetted parts are 316L stainless with polished finish; gaskets are food-grade. Pulp and fibres foul plates, so cleanability and CIP compatibility are specified up front.

Drainability and crevice-free design support both food safety and batch changeover between fruit types.

Higher pulp content raises viscosity; the corrugation pattern and velocity are chosen to keep heat transfer high without excessive pressure drop that could damage the product.

Plate exchangers serve most juice pasteurization; tubular or scraped-surface units are reserved for very high pulp or particulate products that would foul plates.

Duty follows juice flow, specific heat, temperature lift and fouling allowance. The plate count is set for the required overall coefficient and acceptable pressure drop.

The exchanger links reception, pasteurization, cooling and filling, with flow diversion protecting under-processed product. Utilities are matched to the pack.

Provide juice type and pulp content, flow, temperatures, fouling expectation and any standard (3-A / EHEDG). The supplier returns a plate arrangement and utility loads.

For a juice processing heat exchanger, the purchase decision should be closed by verifying documents that prove the delivered unit matches the agreed specification, not by the nameplate alone. Hygiene validation and pulp-fouling cleanability are the decisive checks.

Request material certificates for every wetted plate, shell course or tube, together with the welding procedure and welder qualification records. Critical seams should carry radiographic or ultrasonic examination reports, and the pressure test should be witnessed or certified by a recognised third party.

For export, confirm the applicable code marking - ASME U-stamp or CE/PED - and any destination-required inspection sign-off before shipment. Material traceability from mill certificate to finished vessel protects both parties if a field issue arises later.

A practical acceptance check is to confirm the calibrated operating range, not only the rated value, covers your worst-case duty, and that spares (gaskets, bolts, tube bundles where relevant) are specified because the service will eventually need maintenance.

A juice heat exchanger is a hygiene-led, fouling-aware device: 316L polish, drainable design and CIP survival decide fitness, while regeneration cuts energy.

Use a multi-section plate pack for pasteurization, size from flow and temperature lift, and confirm cleanability before purchase.

It heats juice for pasteurization and cools it for aseptic filling, with heat recovery between the streams.

Recovering heat from hot pasteurized juice to pre-warm incoming juice cuts energy and utility load.

Plate for standard juice; tubular or scraped-surface for high pulp or particulate product.

3-A or EHEDG where required by market, supporting cleanability validation.

It keeps juice at pasteurization temperature for the required time.

Flow diversion sends off-spec product away from the filler.

Steam or hot water for heating, chilled water or glycol for cooling.

Conservative design, controlled velocity and a documented CIP routine.

Juice type, pulp content, flow, temperatures, fouling and any hygiene standard.
