What is Prawn feed making machine?
Prawn feed making machine is a special equipment used to process a variety of raw materials into prawn pellet feed, mainly used in aqua feed plants and large and medium-sized breeding enterprises. Through reasonable mechanical structure and process flow, this equipment can produce nutritionally balanced, easy-to-digest and absorb sinking pellet feed for prawn. Compared with traditional feed processing methods, it not only improves feed utilization, but also significantly reduces production costs. It is an important equipment for modern prawn farming feed production.
Prawn feed machine is widely used in the industrial production of various prawn feeds, such as special formula pellet feed manufacturing for white prawn, Macrobrachium rosenbergii, and Penaeus monodon. It can also be used for the production of sinking feed for other aquatic animals such as fish and crabs. Whether used independently or as the core equipment in a shrimp feed plant, it can customize the production capacity and pellet specifications according to customer needs. As a type of shrimp feed pellet machine, it is an indispensable and important piece of equipment in modern aquaculture feed manufacturing.
The equipment usually includes multiple links such as automatic batching, crushing, mixing, conditioning, granulation and cooling. First, various raw materials are weighed by the batching system and then enter the micro-crusher to crush to a suitable pellet size; then they are evenly mixed in the mixer and heat-conditioned by the conditioner to improve the maturity of the raw materials.
The mixed and tempered materials enter the main machine, are extruded into pellets by the ring die and roller, and finally cooled and shaped by the cooler. The equipment supports 1.5-8mm pellet specifications, which can meet the growth needs of prawns at different stages. The pellets are stable, strong in water submergence and good in palatability.

Prawn feed making machine: Raw materials
Choosing the right raw materials is crucial to producing high-quality feed that can meet the nutritional needs of prawn growth. The following are several commonly used and effective prawn feed pellet raw materials:
Soybean Meal
Soybean meal is an important source of plant protein, rich in essential amino acids, easy to digest and absorb, and is one of the most commonly used basic raw materials in prawn feed.
Wheat
Wheat not only provides carbohydrates as an energy source, but also has good adhesiveness due to its natural gluten, which helps to form feed pellets.
Fish Meal
Fish meal contains high-quality animal protein and fatty acids, which can increase the nutritional density of feed, enhance prawn immunity, and promote rapid growth.
prawn Head Powder
Prawn head powder is rich in animal protein and natural attractants, which can enhance palatability and is an economical choice to replace some high-priced raw materials.
Advantages of Prawn Feed Pellets
Prawn feed making machine plays a crucial role in modern aquaculture as the demand for efficient and sustainable practices continues to rise globally. As a result, prawn feed pellets have become the preferred choice for prawn farmers seeking to improve productivity, feed efficiency, and environmental performance. Often produced as part of an integrated fish feed production line, these pellets are processed using advanced technologies and offer numerous benefits that directly contribute to healthier prawn and higher economic returns.
Prawn feed pellets are formulated using scientifically balanced ingredients such as soybean meal, fish meal, prawn head powder, and various grains. These components provide a complete nutritional profile rich in protein, essential amino acids, vitamins, and trace minerals, which are critical for supporting healthy growth, molting, and immunity in prawn throughout all life stages.
Unlike powder or crumbled feed, pellets have excellent sinking properties, making them ideal for bottom-feeding prawn species. Their compact structure and appropriate density ensure they remain stable in water, reducing feed loss and allowing prawn ample time to consume the feed.
Moreover, prawn feed pellets are known for their excellent palatability. The uniform size and smooth texture of the pellets encourage prawn to feed actively, while the digestibility of the formula improves feed conversion ratios (FCR), helping farmers reduce feeding costs and improve overall yield.
Another key advantage is the water stability of prawn feed pellets. High-quality pellets remain intact in water for up to two hours or more without disintegration, minimizing nutrient leaching and reducing the risk of water pollution—an essential factor in maintaining a healthy aquaculture environment.
Additionally, the low moisture content and high density of prawn feed pellets make them easy to package, store, and transport. This ensures they remain fresh over time and supports the logistical needs of commercial-scale prawn farming operations.

Related Machines of Prawn Feed Making Machine
Some customers choose a prawn feed making machine specifically designed for shrimp feed production. However, others opt for a floating fish feed extruder machine to produce prawn feed as well. This is because floating fish feed extruders—thanks to their flexibility—are capable of producing a wide variety of floating, sinking, and slow-sinking feed pellets, suitable not only for fish but also for shrimp, crabs, and other aquatic animals. These extruders are essential equipment in both small-scale and commercial aquafeed production lines.
Floating fish feed extruders are generally divided into two types: single-screw extruders and twin-screw extruders. Below is a detailed introduction to these key machines and the supporting equipment commonly used in a small prawn feed production line.
Single screw floating fish feed extruder machine
The single-screw floating fish feed extruder is specifically designed for producing floating aquatic feed pellets. It uses a high-temperature, high-pressure extrusion process driven by a single rotating screw to puff and shape the feed, allowing it to float on the water surface—ideal for prawn and fish feeding.Depending on the process requirements, it can be operated in dry or wet mode:
Dry Type Single Screw Extruder
Requires no steam system or pre-conditioning. The extrusion heat is generated solely through mechanical friction and pressure. It is low in cost and suitable for small production capacities.
Wet Type Single Screw Extruder
Incorporates a steam conditioning system to pre-cook the raw materials before extrusion. This improves pellet quality, gelatinizes starch, and denatures proteins. It is ideal for medium to large-scale operations that demand consistent pellet quality.
Twin screw floating fish feed extruder machine
The twin-screw floating fish feed extruder is a more advanced and versatile solution, widely used in the production of high-quality shrimp and fish feed. It features two intermeshing screws that mix, compress, cook, and shape the feed under high temperature and pressure.
The twin-screw extruder is especially suitable for shrimp feed production, as it offers better control over pellet density and surface structure, which are critical for shrimp feeding behavior.

What kind of feed is good for the growth of fish and prawn?
With the rapid development of the global aquaculture industry, especially driven by the growing market demand in countries such as India, a scientific and efficient feed system has become a key factor in the success of aquaculture. Among them, puffed floating fish and prawn feed is gradually replacing traditional feed due to its significant nutritional value and economic benefits, and has become the preferred solution for promoting the rapid and healthy growth of fish and prawn.
1. Puffed feed promotes rapid growth and efficient conversion
Puffed feed is a porous granular feed that has been processed by high temperature and high pressure puffing process, with good palatability and digestibility. During its production process, the starch in the raw materials is cooked and the fat is stabilized, while the fiber and cell wall structure are destroyed and softened, thereby greatly improving the nutrient absorption rate of the feed. Studies have shown that compared with traditional feed, floating puffed feed can increase feed conversion efficiency by 10%-20%, making fish and prawn grow faster, higher yield, and significantly improving economic benefits.
2. Easy to observe feeding and control water quality
Floating extruded feed can float on the water surface for a long time. It usually does not sink in the water within 12 hours and does not dissolve within 2 hours. It is easy to observe the feeding status of fish and prawn, reasonably adjust the feeding amount, and prevent waste. In addition, floating feed can effectively reduce the feed from sinking to the bottom of the pond and fermenting, thereby avoiding water pollution and ensuring the stability of the breeding environment.
3. Wide application and improved breeding management efficiency
Extruded feed is divided into three types: floating, slow-sinking and sinking according to the feeding habits of different fish. Among them, many freshwater fish such as tilapia and grass carp are particularly suitable for the use of floating extruded feed. For benthic aquatic products such as prawn, suitable extruded slow-sinking feed can also be selected according to their feeding behavior. The standardized extruded feed system not only improves the feeding efficiency, but also promotes the standardization and refinement of breeding management.
4. Stable storage, suitable for commercial production
Floating extruded feed has low water content, high dryness of finished products, good storage stability, and is convenient for long-term storage and large-scale transportation, providing convenience for commercial breeding.
