APEX Launches 100,000-Ton Cassava Pelletizing Project in Cambodia, Breaking Industry Technical Barriers
PHNOM PENH, Cambodia — APEX has officially launched a new 100,000-ton annual capacity cassava pelletizing project in Cambodia. This project marks a significant breakthrough in the Southeast Asian green energy and premium feed markets by solving a long-standing industry challenge: pelletizing ultra-fine, low-moisture cassava powder without any additives.
The Breakthrough: Pure Physical Pelletization for 100-Mesh Fine Powder
The client's raw material presented a severe technical challenge: a highly volatile, 100-mesh ultra-fine powder with an exceptionally low moisture content of only 10%. Lacking specialized expertise, many equipment manufacturers typically advise adding chemical binders to force bonding, which degrades the starch purity and lowers the market value for alcohol and high-end feed industries.
Dingrui solved this by deploying its custom-engineered, high-intensity feeding and compression system. In a recent live material trial, Dingrui successfully achieved 100% additive-free physical pelletization in a single run. The resulting cassava pellets boast high density, smooth surfaces, and excellent durability, fully preserving the raw material's natural components and export standards.
Proven Track Record: 5 Years of Success in Thailand
APEX technical solution is backed by years of large-scale industrial validation. In 2020, APEX commissioned a 15 t/h (tons per hour) cassava pelletizing line in Thailand. That system has operated continuously and stably for over five years under high-intensity conditions, proving the superior wear resistance and low maintenance costs of Dingrui’s core machinery.
With firsthand operational data from the Thailand project, Dingrui provides the Cambodian project with a complete, low-risk, and high-ROI Engineering Procurement (EP) solution—spanning material analysis, tailored conditioning, and post-launch optimization.
As the 100,000-ton Cambodian project rapidly progresses, Dingrui continues to empower global investors to unlock the maximum value of Southeast Asia's rich cassava resources.

How do you choose an aquafeed extruder when producing aquatic feed?

How do you choose an aquafeed extruder when producing aquatic feed?
Choosing the right aquafeed extruder is one of the most critical decisions you will make, as aquatic feed requires much higher precision than standard poultry or cattle livestock feed. Fish and shrimp have unique dietary needs, and the pellets must behave correctly in water.
To choose the right aquafeed extruder, you need to evaluate machinery based on the following five core factors:
1. Single-Screw vs. Twin-Screw Extruder
This is the first and most important technological choice you will make.
Single-Screw Extruders:
How they work: Have one rotating screw inside the barrel. They rely heavily on barrel friction to create heat and pressure.
Pros/Cons: Cheaper upfront and easier to maintain. However, they struggle with high-fat, high-moisture, or highly sticky ingredients.
Best For: Basic floating fish feeds (like for tilapia or carp) with standard grain formulations and moderate nutritional profiles.
Twin-Screw Extruders:
How they work: Have two co-rotating, intermeshing screws. They offer positive displacement, meaning they actively push material forward regardless of its stickiness or fat content.
Pros/Cons: Higher initial investment and more complex maintenance. However, they offer superior mixing, precise control over pellet density, and excellent raw material flexibility.
Best For: High-end formula feeds (like for salmon, trout, or shrimp), sinking pellets, micro-pellets (under 1.5 mm), and feeds with high oil or fresh meat inclusion.
2. Density and Buoyancy Control (Floating vs. Sinking)
Different aquatic species feed at different levels of the water column. Your extruder must be able to match these requirements:
Floating Feed (e.g., Tilapia, Catfish): Requires an extruder that can reach high temperatures and high starch gelatinization to create a highly expanded, porous structure that traps air.
Slow-Sinking Feed (e.g., Salmon, Trout): Requires precise pressure relief mechanisms (like a venting barrel or a vacuum system) right before the die to prevent the pellet from expanding too much.
Fast-Sinking Feed (e.g., Shrimp): Requires a machine capable of handling high-density formulas with lower expansion ratios so the feed drops immediately to the seabed or pond floor and stays stable for hours without dissolving.
3. Die Capability and Pellet Size Range
Aquatic life stages require vastly different pellet sizes, from tiny hatchlings to mature adult fish.
Check the minimum and maximum pellet sizes the extruder can cleanly cut. Producing 0.5 mm to 1.5 mm micro-pellets requires an extruder with incredibly stable pressure distribution across the die plate and a high-precision, high-speed face cutter.
Ensure the die plates are quick and easy to change out to minimize downtime when switching product lines.
4. Pre-Conditioner Efficiency
For aquafeed, a massive portion of the cooking actually happens before the material enters the extruder barrel.
Look for an extruder paired with a high-quality, dual-shaft or differential-diameter pre-conditioner.
The conditioner should allow the raw material to blend with steam and water for a sufficient retention time (usually 90 to 180 seconds). Proper pre-conditioning pre-gelatinizes the starch, reduces mechanical wear on the extruder screw, and significantly increases production capacity.
5. Wear Resistance and Material Quality
Aquafeed formulas often use highly abrasive ingredients like fish meal, bone meal, and mineral supplements.
Look for extruders built with high-wear-resistant alloys for the screws and barrel liners (such as nitrided steel or bimetallic materials).
Investing in a machine with segmented screw elements allows you to replace only the specific worn-down sections rather than replacing the entire screw shaft, saving significant maintenance money over time.

What issues should be considered during the actual operation of a feed extrusion production line?
2026-06-15
Operating a feed extrusion production line—especially for specialized aquatic feed or pet food—requires precise control over temperature, moisture, and mechanical forces. Because extrusion relies on "cooking" the material under intense pressure, small deviations can ruin an entire batch.
Here are the critical issues you must monitor and control during actual operation:
1. Moisture and Steam Control
Moisture is the single most critical factor in extrusion. It acts as a plasticizer, allowing the starch in the raw materials to gelatinize.
Pre-conditioning Moisture: Ensure the steam conditioner adds uniform moisture (typically bringing the mix to 18%–20% moisture before it enters the extruder barrel). If it’s too dry, the machine can clog or overheat; if it’s too wet, the pellets will lose their shape and become mushy.
Steam Quality: Use dry, saturated steam. Condensate (water droplets) in the steam lines will cause uneven moisture distribution and structural defects in the final pellets.
2. Temperature Management (The Cooking Profile)
An extruder barrel is divided into multiple heating zones, and the temperature must rise progressively as the material moves toward the die.
Friction vs. External Heat: While the barrel has external heaters, a massive amount of heat is generated by internal mechanical friction (shear). You must balance the cooling water jacket and the heating elements to keep the zones at their precise target temperatures (often ranging from 100°C to 150°C near the discharge).
Starch Gelatinization: If the temperature is too low, the starch won't fully cook, leading to poor pellet stability in water and lower digestibility for the animals.
3. Screw Speed and Feed Rate Balance
The relationship between how fast raw material enters the machine (feed rate) and how fast the screw turns (RPM) dictates the "fill degree" of the extruder.
Overfeeding: If the feeding speed is too fast for the screw RPM, the barrel will choke, causing the motor to draw too much current and potentially tripping the circuit breaker or shearing a key.
Underfeeding: If the feed rate is too low, the material won't build up enough pressure at the die, resulting in poorly expanded, dense pellets.
4. Expansion Ratio and Die Monitoring
The sudden drop in pressure as the material exits the die causes water to flash into steam, expanding the pellet.
Buoyancy Control: For floating fish feed, you need a high expansion ratio. For sinking feed, you need less expansion. This is controlled by adjusting the temperature right before the die and managing the formula's starch content.
Die Blockages: Fibrous materials or poorly ground grains can easily clog the small holes in the die plate. Operators must monitor the pressure gauge right behind the die; a sudden spike in pressure usually indicates a blockage.
5. Startup and Shutdown Procedures (Preventing Clogs)
The moments when you turn the machine on and off are when the highest risk of equipment damage occurs.
Startup: Never start feeding raw material into a cold extruder. Run water and a purging compound (or a base grain mix) through the machine until it reaches operating temperature before introducing the actual formula.
Shutdown (Purging): Never stop the machine with feed mixture still inside the barrel. As the barrel cools, the cooked starch will harden like concrete, locking the screw in place. Always flush the barrel with water or a specific cleaning meal until the discharge runs completely clear.
6. Wear and Tear Inspection
Extrusion involves high friction, especially when processing abrasive raw materials like bone meal or minerals.
Screw and Liner Wear: As the screw segments and barrel liners wear down, the clearance between them increases. This reduces the machine's ability to build pressure, leading to a drop in capacity and poorly expanded pellets. Check these tolerances regularly during scheduled maintenance.

Commercial Feed Production Line
2026-06-15
Choosing the Right Feed Production Line: Types, Machinery, & Buyer’s Guide
Investing in a commercial feed production line is a major step toward scaling your farm or animal feed business. However, finding the right setup depends heavily on your specific livestock, intended scale of operation, and budget. Choosing mismatched machinery can lead to high operational costs or premature equipment wear.
In this comprehensive guide, we break down the primary types of animal feed manufacturing plants available, explore the essential machinery required, and provide a step-by-step framework to help you choose the ideal feed pellet production line for your business needs.
1. Types of Feed Production Lines
Feed production lines are generally categorized by their die design (how the pellets are formed) and their mobility/scale.
Flat Die Feed Production Line
How it works: Uses a flat horizontal die with rollers moving over it to press the feed through the holes.
Capacity: Typically smaller scale, ranging from 100 kg/h to 1,000 kg/h.
Best For: Small to medium-sized farms, startups, or home-use operations. It is compact, easy to operate, affordable, and handles simple formulations well.
Ring Die Feed Production Line
How it works: Features a vertical, cylindrical ring die. Raw material is fed into the center and forced outward through the die by internal rollers.
Capacity: Industrial scale, ranging from 1 ton/h to over 20 tons/h.
Best For: Large-scale commercial feed mills and massive livestock farms. They are highly efficient, offer superb pellet uniformity, and feature steam conditioners to pre-cook the feed for better digestibility.
Extruded Feed Production Lines
How it works: Uses high temperature, pressure, and moisture (extrusion technology) to expand and cook the feed.
Best For: Aquatic feed (floating or sinking fish/shrimp pellets) and pet food (cat and dog kibble). It allows the pellets to maintain water stability and float on the surface if needed.
2. Key Components of a Complete Line
If you are buying a complete automated production line, it will typically feature a sequence of machines connected by conveyors:
Crushing System: Hammer mills to grind grains (corn, wheat, soybean meal) into fine powder.
Batching & Mixing System: Precisely weighs ingredients and blends them uniformly.
Pelleting System: The flat die, ring die, or extruder that shapes the feed.
Cooling & Drying System: Counterflow coolers lower the pellet temperature and moisture content so they don't mold.
Packaging System: Automatically weighs and bags the finished feed for storage or sale.
3. How to Choose the Right Line for Your Needs
To pinpoint exactly what machinery you need, evaluate your operation against these four criteria:
A. Your Daily Production Volume (Scale)
Under 1 ton per hour: A small Flat Die Line or a modular mini-plant is sufficient. It keeps your upfront investment low.
Over 1 ton per hour: You need a Ring Die Line. Running a small machine for too many consecutive hours will cause premature wear and high maintenance costs.
B. The Target Animal & Feed Type
Poultry (Chickens/Ducks): Can easily digest both mash (powdered) feed and standard small pellets. A basic flat die or small ring die system works great.
Livestock (Cattle/Sheep/Pigs): Often require larger pellets with high fiber content (like alfalfa or straw). Ring die systems with robust conditioning are ideal for handling tough, fibrous materials.
Fish & Pets: You will almost certainly need an extruder production line to achieve the correct buoyancy, shape, and nutrient stability.
C. Raw Material Properties
Consider what ingredients you have local access to. If you are using heavy grains like corn and soybean meal, standard grinders work perfectly. If you are mixing in heavy amounts of grass, molasses, or liquids, you will need specialized mixers and feeders to prevent clogging.
D. Investment Budget vs. Total Cost of Ownership (TCO)
Don't just look at the sticker price. While a manual, small-scale line is cheaper upfront, it requires high labor costs. Fully automated ring die lines have a higher upfront cost but offer massive energy efficiency, low labor costs, and a much longer machine lifespan, yielding a better Return on Investment (ROI) over time.
