Industrial feed fish washing and sorting machine with extended conveyor design for aquaculture farms and feed processing plants. Integrates fish cleaning and manual sorting in one system. Factory-direct manufacturer offering commercial-grade, stainless steel equipment with customizable capacity and OEM solutions.
In modern aquaculture and feed processing industries, feed fish cleaning plays a critical role in ensuring biosecurity, product quality, and stable downstream production. The Fish Washing & Sorting Machine is specifically designed to integrate washing and manual sorting into a single automated system, providing a hygienic, efficient, and scalable solution for feed fish pre-processing.
This machine is widely used in aquaculture farms, feed fish processing plants, and pet food factories, replacing labor-intensive manual washing with a standardized and controllable cleaning workflow.
Conventional feed fish cleaning relies heavily on manual soaking, rinsing, and hand sorting. This approach often leads to:
Inconsistent cleaning results due to operator differences
Incomplete removal of mud, slime, sand, and surface contaminants
High labor costs and physical workload
Difficulty scaling production during peak seasons
Increased risk of secondary contamination
As production volumes increase, manual cleaning becomes a major bottleneck affecting both efficiency and hygiene compliance.
The Fish Washing & Sorting Machine is engineered to solve these challenges through automation and intelligent design. It integrates:
Water soaking and bubble cleaning
High-pressure spray washing
Adjustable-speed conveying
Extended manual sorting platform
This integrated structure allows washing and sorting to be completed on one machine, significantly improving efficiency and operational control.
The washing tank is constructed from food-grade SUS304 stainless steel, offering excellent corrosion resistance in wet and saline environments. The tank bottom features a curved design to facilitate sediment collection and wastewater discharge.
A built-in bubble generator produces dense micro-bubbles that gently agitate the fish. As bubbles burst, they remove slime, fine sand, and debris from the fish surface, especially effective for small feed fish such as sardines, anchovies, and mixed trash fish.
Multiple spray nozzles are installed above and along the sides of the tank. These deliver high-pressure water jets that flush away loosened impurities, preventing re-attachment and cross-contamination.
A lengthened conveyor belt transports cleaned fish to the sorting platform. Conveyor speed is controlled by a frequency inverter, allowing precise adjustment according to fish size and cleaning requirements.
The extended sorting table allows 6–8 workers to operate simultaneously, making it easy to remove damaged fish, foreign materials, or undesired species in one centralized area.
Soaking Stage
Feed fish enter the cleaning tank, where surface dirt and contaminants are softened.
Bubble Cleaning Stage
Micro-bubbles lift and gently scrub fish surfaces, loosening slime and sand.
Spray Washing Stage
High-pressure water jets remove detached impurities and maintain clean water flow.
Conveying Stage
Cleaned fish are lifted from the tank via the conveyor belt.
Sorting Stage
Operators perform visual inspection and selection before further processing or feeding.
This continuous workflow ensures stable cleaning quality while protecting fish integrity.
The combination of soaking, bubbling, and spray washing achieves deep cleaning without mechanical damage.
Water-based cleaning and smooth conveying minimize stress, breakage, and deformation.
Machine length and conveyor speed can be customized to match different production capacities.
One machine replaces multiple manual washing and sorting stations, significantly reducing workforce needs.
All product-contact parts are made from food-grade stainless steel, compliant with food safety standards.
