Fish processing conveyors are an essential part of the fish processing industry. These conveyor systems help efficiently transport fish through the various stages of processing, from when they are caught to when they are packaged and ready for distribution.

Introduction
The use of conveyors in fish processing dates back to the early 20th century. At the time, fish processing was labour-intensive, with workers manually handling and moving fish from one stage of processing to the next. This not only made the process slow and inefficient, but it also posed several challenges, including the risk of injury to workers and the potential for contamination of the fish.
It’s introduction revolutionized the industry. These conveyor systems allowed for the automatic movement of fish through the processing stages, reducing the need for manual labour and improving overall efficiency. In addition, conveyors helped to reduce the risk of injury to workers and improved the overall hygiene of the fish processing process.
Types of fish processing conveyors
There are many different types of fish processing conveyors, each designed to meet the specific needs of a particular fish processing facility. Some of the most common types of fish processing conveyors include:
- Belt conveyors: Belt conveyors are the most common type of fish processing conveyor. They consist of a loop of flexible material, typically rubber or PVC, that is driven by a motor. Fish are placed on the conveyor belt and transported from one processing station to the next. Belt conveyors are versatile and can be used for a wide range of applications, including sorting, grading, and transporting fish.
- Screw conveyors: Screw conveyors are another common type of fish processing conveyor. They consist of a rotating helical screw that is enclosed in a tube or trough. As the screw turns, it moves fish along the conveyor from one processing station to the next. Screw conveyors are often used for handling fish that are too small or delicate for belt conveyors.
- Vibratory conveyors: Vibratory conveyors are a type of fish processing conveyor that uses vibrating plates or screens to move fish along the conveyor. As the plates or screens vibrate, they create a gentle motion that helps to move fish through the processing stages without damaging them. Vibratory conveyors are often used for handling delicate fish, such as salmon or other species that are prone to damage.
- Flighted conveyors: Flighted conveyors are a type of fish processing conveyor that uses a series of evenly spaced flights or blades to move fish along the conveyor. As the flights rotate, they lift fish off the conveyor belt and move them forward. Flighted conveyors are often used for sorting and grading fish by size or other characteristics.
Fish processing conveyors are typically made of stainless steel or other materials that are resistant to corrosion and easy to clean. This is important because fish processing facilities must maintain a high level of hygiene to prevent the growth of bacteria and other contaminants. In addition, most fish processing conveyors are designed to be easily disassembled for cleaning and maintenance.
Benefits of using fish processing conveyors
The use of fish processing conveyors has many benefits. In addition to increasing efficiency and reducing the need for manual labour, conveyors can also help to improve the quality of the final product. By automating the movement of fish through the processing stages, conveyors can help to ensure that fish are processed quickly and consistently, which can help to preserve their freshness and flavour.
Conveyors can also help to reduce the risk of injury to workers in the fish processing industry. Manual handling of fish can be physically demanding and can lead to musculoskeletal disorders and other injuries. By automating the handling of fish, conveyors can help to reduce the risk of hazards.
Drawbacks of using fish processing conveyors
There are several drawbacks that should be considered when deciding whether to use them in a particular fish processing facility. Some of the potential drawbacks of it include the following:
- Initial cost: It can be expensive to purchase and install. In addition to the cost of the conveyor itself, there may also be costs associated with modifying the processing facility to accommodate the conveyor. This can be a significant barrier for small fish processing facilities that may not have the financial resources to invest in conveyors.
- Maintenance and repair: Fish processing conveyors require regular maintenance and may need to be repaired or replaced over time. This can be a high ongoing cost for fish processing facilities that use conveyors. In addition, conveyors may need to be shut down for maintenance or repair, which can disrupt the processing of fish and reduce overall efficiency.
- Limitations on the size and type of fish: Some types of fish processing conveyors are not suitable for handling large or heavy fish. In addition, some conveyors may not be able to handle delicate or fragile fish without damaging them. This can limit the types of fish that can be processed using a particular conveyor system.
- Risk of contamination: Fish processing conveyors can be a potential source of contamination if they are not properly designed and maintained. In particular, conveyor belts and other surfaces that come into contact with fish can harbour bacteria and other contaminants. This can be a significant concern in fish processing facilities that must maintain strict hygiene standards to prevent the growth of bacteria and other contaminants.
- Risk of injury: Although it can help to reduce the risk of injury to workers by automating the handling of fish, there is still a risk of injury associated with using conveyors. Workers may be injured by moving parts of the conveyor or by coming into contact with fish that are being transported on the conveyor. In addition, conveyors can create noise and other potential hazards that can pose a risk to workers.
Overall, while fish processing conveyors can offer many benefits, they also come with some significant drawbacks that should be considered before deciding to use them in a fish processing facility. In order to maximize the benefits and minimize the drawbacks of using conveyors, it is important to carefully consider the specific needs of the facility and choose the right type of conveyor for the job.
What is the equipment used in fish processing?
There are many different types of equipment that are used in fish processing. Some of the most common types of equipment include:
- Fish processing conveyors: As mentioned above, it is used to automate the movement of fish through the processing stages, from the time they are caught to the time they are packaged and ready for distribution.
- Fish sorting and grading equipment: Fish sorting and grading equipment is used to sort fish by size, weight, or other characteristics. This equipment can include conveyor belts with flights or other sorting mechanisms, as well as cameras and other sensors that can be used to sort fish automatically.
- Fish cutting and deboning equipment: Fish cutting and deboning equipment is used to remove the bones and other inedible parts of fish. This equipment can include knives, saws, and other cutting tools, as well as machines that can automate the cutting process.
- Fish freezing and refrigeration equipment: Fish freezing and refrigeration equipment are used to preserve the freshness and flavour of fish. This equipment can include blast freezers, cold storage rooms, and other refrigeration systems that are designed specifically for fish processing.
- Fish packaging equipment: Fish packaging equipment is used for packaging fish for distribution and sale. This equipment can include vacuum sealers, packaging machines, and other tools that are designed to protect fish during transportation and storage.
- Fish cleaning equipment: Fish cleaning equipment is used to clean fish before they are processed. This equipment can include hoses and other washing tools, as well as machines that can automate the cleaning process.
- Fish cooking equipment: Fish cooking equipment is used to cook fish that will be sold fresh or frozen. This equipment can include fryers, ovens, and other cooking tools that are designed specifically for fish processing.
Summary
Overall, the specific equipment used in fish processing will depend on the type of fish being processed and the specific needs of the processing facility. It is important to choose the right equipment to ensure that fish are processed efficiently and with high quality.
