CIP Cleaning Hygienic Soy Milk Decanter Centrifuge Stainless Steel LWS550

Hygiene is the part of separation that gets audited. A decanter that separates well but cannot be cleaned verifiably will fail a food safety inspection sooner or later, and the cost of that failure is far higher than the price difference between machines. The LWS550 is built for plants operating under HACCP, BRC or a customer audit regime, with a cleaning design that can be documented rather than assumed.

The 550 mm bowl runs at 3,500 rpm and produces 3,770 G at a rated capacity of 18 to 24 tonnes per hour. What distinguishes this model is the sanitation architecture: a fully welded bowl hood with integrated spray nozzles, a closed solids discharge chute that keeps the machine room free of aerosol, slope-drained surfaces with no horizontal ledges, and a control system that executes a validated CIP sequence with recorded temperatures, flow and duration. Every product-contact surface is AISI 316L, polished to Ra 0,8 micron, with FDA-compliant elastomer seals and a bowl that drains completely by gravity.

• Validated CIP Sequence: The PLC runs a pre-set wash, rinse and sanitise cycle with monitored temperature, flow and contact time, and logs the cycle record for audit purposes
• Full Coverage Spray Nozzles: Nozzles integrated into the bowl hood and the discharge chute wash the areas that manual cleaning normally misses, so no parts have to be opened between production runs
• Closed Discharge Design: The solids chute is fully enclosed and vented, keeping okara and wash water out of the machine room and meeting the housekeeping standards of modern food plants
• Hygienic Surface Finish: All wetted parts are 316L stainless polished to Ra 0,8 micron, with crevice-free welded joints, radiused corners and no threaded connections in the product path
• Fast Product Changeover: A complete CIP cycle followed by a rinse takes about forty-five minutes, allowing a multi-product beverage plant to switch between soy, oat and nut bases within one shift
• Audit-Ready Documentation: Material certificates, surface finish reports, elastomer compliance statements and a cleaning validation protocol are supplied with the machine for inclusion in the plant food safety file

The LWS550 is chosen by beverage plants operating under third-party audits, by soy milk and plant-based milk producers running multiple products on one line, and by contract manufacturers who must demonstrate cleaning validation to their customers. Its closed discharge and validated wash cycle also make it suitable for installations where the machine room sits close to filling areas and airborne contamination is unacceptable.

Beyond soy milk, it is used on oat, almond, rice and coconut bases, on fruit puree lines that require allergen changeover control, and in pharmaceutical and nutraceutical fermentation plants where the same hygiene argument applies. In each case the economic case is the same: less manual cleaning labour, shorter changeovers, fewer rejected batches after wash and a documented hygiene record that satisfies auditors without a scramble.

Shipping uses a steel-framed export case with the bowl locked on transport supports, the control cabinet in a separate foam-lined crate, and all seals bagged and labelled by position. Material certificates, surface finish reports and elastomer compliance statements travel in a dedicated documentation folder inside the case.

Factory testing includes a full CIP cycle run with logged temperature and flow data, a four-hour water run and a two-hour soy slurry run, so the plant can verify the cycle record format against its own audit requirements before acceptance. The warranty is 24 months on the rotating assembly and 12 months on wear parts. Huading supports cleaning validation on site and supplies a written protocol template that can be adapted to the customer food safety management system.
