Huading Soy Milk Centrifuge CIP Cleaning Hygienic Design 8000L H Automatic Discharge

Food safety audits increasingly ask two questions about a separator: can it be cleaned without being opened, and can the cleaning be proven. The Huading DHC-450H answers both. It is a hygienic disc stack centrifuge with an automatic CIP circuit, a fully drainable bowl casing and a control system that records every cleaning cycle alongside the production run, so the evidence an auditor wants is already in the log.

Rated at 8000 litres per hour with 7500 G, the machine is aimed at soy milk and plant based beverage plants that need high clarity plus a documented hygiene routine. Surfaces are polished to below 0.8 micron, the product side is isolated from the drive and from the seal water by a double barrier, and the bowl opens to a completely drainable frame with no horizontal ledges where residue can collect.

• Automatic CIP with cycle records: the built-in cleaning program circulates detergent, rinses and drains without opening the machine, and each cycle is time stamped in the controller for audit purposes.
• Hygienic bowl and casing: SS316L contact parts polished below 0.8 micron, radiused corners, sloped surfaces and a fully drainable frame eliminate the crevices where biofilm forms.
• 7500 G clarification: high g-force removes fine soy solids so the finished milk stays uniform through UHT treatment and long shelf storage.
• Isolated product zone: a double barrier between product and seal water, plus a flushing water seal, keeps the product stream clean and prevents cross contamination.
• Automatic solids ejection: partial ejections clear the bowl during the run and a full ejection empties it at the end, removing manual intervention and reducing operator exposure to hot product.
• Sanitary outlet pump: the centripetal pump delivers 0.2 MPa under closed conditions, feeding the next stage directly with no open tanks and no oxygen pickup.
• Compact sanitary footprint: a 1.45 metre footprint with all connections on one side simplifies installation in an existing hygienic room and keeps pipe runs short and cleanable.

Soy milk enters the closed bowl through a hygienic inlet and is accelerated to 7000 rpm. In the disc stack, fine solids are thrown outwards under 7500 G and collect in the sludge space, while clarified product moves inward and leaves through the centripetal pump. When the cycle demands it, the bowl opens briefly at the periphery and ejects solids into a closed collector. During CIP, detergent and rinse water are circulated through the same paths under program control, and the drainable casing ensures no liquid is trapped.

The DHC-450H suits soy milk, tofu whey recovery, plant based beverage bases, coconut and nut milk clarification, and any food process where cleaning validation and a documented hygiene routine are required. It is frequently specified by plants supplying retail or export markets with third party audits.

The machine is shipped in a plywood case with the bowl locked, the damper secured and desiccant added, with the control cabinet in a separate crate. Documents include general arrangement drawings, hygienic design statement, surface finish certificates, material certificates, CIP program description, operation and maintenance manuals and a balancing certificate. Installation supervision, cleaning validation support and operator training are available.
