The price of extruder machines for fish feed varies according several factors including size, capacity brand and country. The average price for a fish feed machine is between $2,000 and $50,000. Machines with smaller capacities are usually cheaper while machines with larger capacities are more expensive.

Other factors which can influence the price of fish feed extruder machines include the type of machine used (dry or damp), the materials that were used to construct the machine and the technology employed in its manufacturing.

For example, a fish feed extruder that uses steam-conditioning technology may be more expensive than a machine of the dry type. This is due to the fact that wet type machines need more sophisticated technology and materials in order to function properly.

The brand is also a factor in the price. Established brands charge more for their machines. In addition, machines made in developed countries like the United States and Europe are more expensive than those manufactured in developing nations.

The cost of the machine alone is not enough to cover the costs associated with the production of fish feed. Calculating the total cost to produce fish feed also requires that other costs be considered, including raw materials, electricity, and labor.

It is therefore important, when selecting a fish feed machine, to consider the machine’s long-term cost and benefits in terms production efficiency and product quality.

How does feed extruder machine work?

Extruder machines for fish feed use heat and mechanical force in combination with heat to cook and shape ingredients into the desired form. The process involves mixing, grinding, conditioning and extrusion.

  • To create a balanced feed, ingredients must be mixed in the proper proportions. This mixture is then finely ground using a hammermill, or grinder. The powdered mixture will then be fed into an extruder machine.
  • The extruder machine comprises a screw conveyer, a barrel and die. The screw conveyor pushes the mixture through a barrel as heat and pressurized are applied. Heat and pressure make the mixture cook and soften. This makes it easier to extrude.
  • In the barrel, the mixture is heated and cooled by a series zones. In the heating zones steam and hot water are used for cooking the mixture. While in the cooling zone cold water is used for cooling the mixture to prevent overcooking.
  • When the mixture reaches its end, it is forced to pass through a die which shapes the mixture in the desired shape, such flakes or pellets. The extruded material is cut into the desired length, and then dried in a dryer.

The screw conveyor is controlled by an operator who can control the speed and temperature of the screw, as well as the pressure, to produce the desired shape and texture of the feed.

Types of Floating Fish Feed Extruder Machine

Extruder machines for fish feed come in two basic types: wet and dry. Extruders have advantages and drawbacks. The type of machine you choose depends on your specific needs.

Dry Type Fish Feed Extruder

Dry extruders are designed to shape and cook ingredients with heat and mechanical force. It involves feeding dry ingredients into an extruder machine where they are cooked and shaped. Dry extrusion can be a cost-effective way to produce fish feed as it uses less energy and water.

The dry extrusion process produces a feed with a much longer shelf life. Dry extrusion reduces spoilage because it removes moisture.

Dry extrusion allows greater control over texture and shape. This allows for the production of feeds with high levels of nutrients and digestibility.

Wet Type Fish Feed Extruder

Wet Extruders are a combination between heat, water, and mechanical force to cook and shape ingredients into desired shapes. In this process, a mixture of wet ingredients is fed into an extruder machine where they are mixed, heated, and shaped. Wet-extrusion produces fish feed at a higher cost because it requires more water and electricity than dry-extrusion.

Wet extrusion has the advantage of producing a highly digestible feed for fish. Wet extrusion hydrates feed, which makes it easier for fish to digest.

Extrusion with water is ideal for the production of feeds that have a high amount of oil. This allows for a greater level of control over the oil in the feed. This allows for the production of feeds tailored to specific nutritional requirements of different fish species.

Wet and dry extruders both have advantages and disadvantages. Dry extrusion can be more cost-effective, and produce a feed which has a longer shelf-life. Wet extrusion creates a feed which is highly digestible and tasty. The selection of machine is based on the needs of the user. For example, the type of fish that will be raised and the nutritional requirements for the feed.

Fish feed formulation is a process that involves developing a formula or recipe for fish food to meet the nutritional needs of fish. Fish feed formulation involves the use of several types of equipment.

  • Mixer: A mixer is a device that mixes ingredients together in the correct ratios. It creates a homogenous product. The mixer can either be vertical or horizontal, depending on your needs.
  • Grinder: The grinder is used to reduce raw materials such as grains and pellets in size before mixing with other ingredients. This is essential for the final feed to have the desired texture.
  • Hammer Mill: This mill grinds and crushes the raw material to produce a fine powder. This is crucial for achieving consistent particle sizes in the final feed. This will improve digestibility and reduce waste.
  • Extruder Machine: A feed extruder creates the final fish food pellets. The ingredients are compressed by a die that shapes the pellets. Heat and pressure is then used to bind them together. Pellets of various sizes and shapes can be produced, depending on user needs.
  • Dryer: The dryer is used after the pellets are extruded to reduce moisture. This is crucial for maintaining the feed’s quality and reducing the chance of spoilage.
  • Cooler: A cooler reduces the temperature of fish feed pellets once they have been extruded. This helps to prevent bacteria and mold growth and stabilizes the feed.
  • Packaging Machine: A packaging machines is used to pack the final pellets of fish feed into bags or containers. This helps to maintain the quality of the fish feed and protect it from contamination while storing and transporting.
