Wet Feed Extruder
Reasonable structure, easy to operate, suitable for mass production

Wet Feed Extruder Overview
Wet feed extruder is a kind of efficient equipment for feed production, which is widely used in the production of animal feed, pet food and aqua feed. Through wet extrusion technology, this equipment treats raw materials under higher temperature and pressure, so as to improve the nutrient composition and digestibility and absorption rate of feed.

Working Principle of Wet Feed Extruder
Main Components and Working Principle
Feeding system
The wet feed extruder has a wide feed opening, equipped with an efficient automatic feeding device to ensure that the raw materials enter the screw conveying area evenly to avoid clogging problems.
Extrusion screw
The extrusion screw is made of high strength alloy material with powerful pushing and mixing functions. The screw speed and pressure are adjustable to ensure that the material is extruded at the right temperature and pressure.
Exhaust system
The equipment is equipped with a highly efficient exhaust system, which can discharge water vapor and gas generated under high temperature and high pressure in a timely manner to avoid affecting the quality of feed during the production process.
Heating and humidifying system
The raw material enters the heating zone through the heating pipes, where the temperature and humidity are precisely controlled. This process helps to optimize the extrusion of the material, improving its plasticity and handling.
Dies and knives
Extruded material is extruded and shaped through the die. The hole diameter of the die can be adjusted according to the demand to ensure the uniformity and proper shape of the feed pellets. Cutting knives are used to control the length of the pellets.
Cooling system
Extruded pellets are quickly cooled by the cooling device to reduce their temperature and prevent excessive heat from affecting the quality of feed. The cooled feed pellets are easier to store and transport.
Features and Advantages of Wet Feed Extruder
Features and Advantages
High performance
Wet feed extruders process raw materials quickly under high temperature and pressure, which can effectively improve the pellet density of feed and enhance the absorption rate of its nutrients.
Nutrient Retention
Through precise control of temperature and pressure, wet extrusion technology is able to effectively retain the nutrients in raw materials while removing harmful substances.
Durable material
Food grade stainless steel contact material, corrosion resistant and pollution free. Key components are specially treated to resist abrasion.
Adaptable
The equipment supports the flexible adjustment of different feed materials and product formulations, and can be customized to different pellet sizes according to production requirements.


Wet Feed Extruder Application Scenarios
Application Scenarios
Animal Feed Processing
Wet feed extruder is widely used in the production of livestock feed for pigs, cows, chickens, etc. It enhances the digestibility and absorption of feed through efficient wet extrusion.
Aquatic feed production
In the field of aquatic feed, wet extruder can produce pellet feed that meets the needs of different aquatic animals, such as fish and shrimp, and improve the utilization rate of feed.
Pet food production
Wet extrusion technology can effectively improve the taste, nutritional value and digestibility of pet food, especially suitable for the production of dog food, cat food and other pet food.
Soybean Processing
Wet feed extruder can be used not only for animal feed, but also for processing plant materials such as grains and soybeans to enhance their nutritional content and digestibility.

Frequently Asked Questions.
Usually 150% – 300%, depending on the characteristics of raw materials, process parameters (temperature, pressure), fine control can be close to the ideal expansion rate.
Yes, the control system supports real-time adjustment of temperature, pressure, screw speed and other parameters, but the adjustment should be gradual to avoid affecting product quality.
Containing feeding system, screw extruder, heating system, molding die, cutting device and control system, each component works together to complete the expansion process.
Clean up the residual material after each use, add lubricating oil to the transmission parts regularly, check the heating element and circuit, and cover the dust cover to prevent the accumulation of dust when the equipment is idle.
Huaxin machinery can be customized according to customer’s special needs, like changing the shape of the mold, adjusting the screw parameters, before customization, we should fully communicate the details, duration, cost.
