High-Pressure Spray Cleaning Machine for Meat and Seafood

High-Pressure Spray Cleaning Machine for Meat and Seafood

Functional Introduction:

The first checkpoint in meat pretreatment, improving cleanliness and food safety. The high-pressure water flow system rapidly removes impurities, blood, and surface adhesions from raw materials, significantly improving the hygiene baseline before pickling and freeze-drying. The machine is designed as an in-line washing stage, not a batch manual operation — the pressure, spray pattern, and conveyor speed are set per product, so the cleaning result is repeatable rather than dependent on operator technique.

Why surface cleaning is a process-control point

In meat and seafood pretreatment, surface contamination is not only a hygiene issue but a downstream processing variable. Residual blood and protein on the surface affect marinade absorption and cure penetration; adhesions on shrimp and shellfish carry grit and microbial load into the freeze-drying chamber. A washing stage that delivers inconsistent pressure leaves some product under-cleaned and some product with damaged surface tissue — the first fails the hygiene specification, the second loses yield and texture. Setting the cleaning parameters per product and holding them across the shift is what makes the stage a control point rather than a rinse.

Performance data

• Spray pressure: adjustable high-pressure water flow, with nozzle configuration and conveyor speed set per product to balance cleaning intensity against surface tissue damage.
• Material compatibility: chicken breast, duck meat, beef, and aquatic raw materials including shrimp and shellfish, plus product entering the line after cold-chain thawing.
• Cleaning coverage:multi-angle spray arrangement covering the full product surface as it passes, including the underside and cut faces.
• Continuous operation: in-line conveyor design matched to the input rate of the pickling and freeze-drying stages downstream, with water circulation and filtration configured to maintain pressure across the shift.
• Hygiene design: stainless steel construction and accessible spray manifolds for routine cleaning and sanitation between production runs.

Application Scenarios:

• Cleaning before slicing chicken breast, duck meat, and beef. Removes surface impurities and blood before the product enters the slicer, protecting both hygiene and cut quality.
• Cleaning the surface of aquatic raw materials such as shrimp and shellfish. Removes grit, adhesions, and surface contamination ahead of peeling, pickling, or freeze-drying.
• Cleaning process after cold-chain thawing. Thawed product carries purge and surface contamination that must be removed before further processing; the washing stage is positioned directly after thawing and ahead of pickling.

Case reference: a leading meat and seafood processing enterprise in East China

Bolaike supplied this high-pressure spray cleaning machine to a leading meat and seafood processing enterprise headquartered in East China, for its prepared-food and freeze-dried product lines. The customer operates across chilled meat, prepared dishes, and aquatic product processing, with a product mix that includes chicken breast, duck meat, beef, shrimp, and shellfish — formats in which the surface hygiene baseline before pickling and freeze-drying directly affects both microbial specification and finished-product yield. The requirement arose from the gap between manual rinsing and the hygiene standard the customer's export and prepared-food customers require. Manual washing delivered inconsistent coverage, and the pressure varied with operator technique; product that passed through under-cleaned carried surface contamination into the pickling stage, while over-washed product lost surface tissue and yield. The machine was specified with adjustable pressure and conveyor speed per product, so that chicken breast, duck meat, and shrimp each run at their own cleaning profile rather than a single fixed setting. The in-line configuration matched the washing stage to the input rate of the downstream pickling and freeze-drying lines. For the customer, the measurable result is a washing stage that delivers consistent surface cleanliness across the full product mix, with the cleaning parameters documented per SKU rather than adjusted by operator experience. The hygiene baseline entering pickling and freeze-drying is now a controlled parameter, which stabilizes both microbial load and marinade absorption — and reduces the rework caused by product that failed the pre-pickling hygiene check.
