H1: IP65 Waterproof Inline Checkweigher: Solve Weight Compliance & Equipment Corrosion for Seafood & Meat Processing Plants

For seafood, frozen meat, sauce and wet food manufacturers worldwide, weight inspection in high-humidity, washdown environments has always been a persistent pain point. Standard checkweighers suffer from rapid corrosion, unstable accuracy and frequent breakdowns under daily high-pressure water cleaning, leading to unplanned downtime, expensive maintenance costs and non-compliant product outflow.
Shanghai Fanchi-tech Machinery Co., Ltd launches the heavy-duty waterproof conveyor checkweigher, purpose-built for harsh wet food production environments. With full 304 stainless steel seamless construction, IP65-rated waterproof enclosure, flip-plate automatic rejection system and industrial-grade anti-vibration design, this model has become the top choice for seafood processors in Southeast Asia, meat plants in North America and sauce manufacturers in Europe.

H2: Core Design Advantages (Matching Real Factory Production Photos)

Every structural detail shown in our workshop photos is engineered to solve wet environment specific challenges:

1. Full 304 Stainless Steel Seamless Welded Frame, 100% Washdown Compatible

The entire machine body, conveyor rack, support legs and rejection mechanism adopt food-grade 304 stainless steel with fully sealed seamless welding. No gaps, crevices or exposed screws where water, blood or seafood residue can accumulate and breed bacteria. It withstands daily high-pressure hot water cleaning and sanitizer spraying, fully meeting HACCP, FDA and EU food safety hygiene requirements.

2. IP65 Waterproof Electrical Enclosure & Sealed Touch Screen

The vertical control cabinet is fully sealed with silicone gaskets, achieving IP65 waterproof and dustproof rating. The industrial touch screen is protected by a transparent waterproof cover, allowing operators to adjust parameters even with wet gloves. All electrical components are isolated from moisture, eliminating short circuit risks in high-humidity workshops.

3. High-Torque Flip-Plate Rejection System for Wet Products

Equipped with a heavy-duty stainless steel flip-plate rejector (visible in the photo), which is far more reliable than push-rod systems for wet, slippery or heavy products. When unqualified products are detected, the flip plate opens instantly to divert overweight/underweight items into a dedicated collection bin, ensuring no product splashing or line blockage.

4. 3-Color Tower Light Status Indicator

A tall, highly visible tri-color (red/yellow/green) warning light provides instant real-time feedback on line status: green for normal operation, yellow for low air pressure or parameter warning, red for rejection or system fault. Operators can monitor multiple lines from a distance, improving production efficiency.

5. Adjustable Anti-Vibration Leveling Feet

Heavy-duty stainless steel adjustable feet with rubber anti-slip pads stabilize the machine on uneven factory floors and isolate vibration from upstream processing equipment, maintaining stable weighing accuracy even in high-speed production environments.

Client Profile

ThaiSeafood Co., Ltd., a leading frozen shrimp and seafood exporter in Bangkok, produces over 15 tons of frozen shrimp packs daily for export to EU and US markets. Their production lines operate 24/7 in high-humidity environments with daily high-pressure water cleaning.

Pre-Cooperation Pain Points

  1. Severe Equipment Corrosion: Their previous standard checkweighers rusted within 6 months, leading to frequent breakdowns and 15–20 hours of unplanned downtime monthly.
  2. Unstable Weighing Accuracy: Moisture intrusion damaged load cells, causing inconsistent weight readings and frequent false rejects, wasting up to 3% of high-value seafood products.
  3. Compliance Risks: Inaccurate weight inspection led to 2–3 retailer complaints monthly about underweight packs, threatening their export certification.

Fanchi-tech Customized Solution

After on-site line assessment, we supplied 4 sets of our IP65 waterproof checkweighers with 300mm wide conveyor belts to accommodate frozen shrimp trays. We also customized the flip-plate rejector with a sealed collection bin to prevent water splashing during rejection. Our engineer team completed on-site installation, calibration and operator training within 4 working days.

Quantifiable Results After 8 Months of Operation

  1. Zero Equipment Corrosion: No rust or water damage observed after 8 months of daily washdowns, extending equipment lifespan from 1 year to over 5 years.
  2. 92% Reduction in Downtime: Unplanned maintenance dropped from 15–20 hours/month to less than 1 hour/month, saving over 180 production hours annually.
  3. 95% Reduction in False Rejects: Stable weighing accuracy reduced seafood waste from 3% to 0.15%, saving approximately $128,000 annually in high-value raw material costs.
  4. 100% Retail Compliance: No underweight pack complaints received, and the company successfully renewed its BRC and HACCP certifications.

“We tried 3 different brands of checkweighers before, and all rusted and broke down within a year. Fanchi-tech’s waterproof checkweigher is the first one that can withstand our daily high-pressure cleaning. It runs stably 24/7, and the accuracy is perfect. It has saved us a huge amount of money in waste and downtime.”

H2: High-Frequency RFQ Questions From Global Buyers

Q1: What is the difference between this waterproof checkweigher and standard models?

A: Standard checkweighers use painted steel frames and non-sealed electrical enclosures, which rust and fail quickly in wet environments. Our waterproof model features full 304 stainless steel construction, IP65 sealed electrical components and corrosion-resistant hardware, designed specifically for daily high-pressure washdowns.

Q2: Can it be used for frozen products and cold storage environments?

A: Yes. We offer low-temperature resistant versions that operate reliably in temperatures as low as -10°C, making them suitable for frozen seafood, meat and cold food processing lines.

Q3: What rejection modes are available for wet products?

A: We recommend our stainless steel flip-plate rejector for most wet food applications, as it avoids the jamming and corrosion issues common with push-rod systems. We also offer air blow rejectors for light, dry products.

Q4: Do you provide on-site installation and training overseas?

A: Yes. We have a global technical service team that can provide on-site installation, calibration and operator training in most countries. We also provide detailed English operation manuals and video tutorials for self-installation.

Q5: Where can I watch real operation videos of this waterproof checkweigher?
