shrimp feed pellet machine

How long does your shrimp feed hold up in water?

If the feed falls apart before the shrimp even get to eat it, farmers won’t be happy – and that hurts your reputation. Worse, every ton of that scattered feed is just wasted money. Want to avoid these headaches? Take a look at RICHI’s shrimp feed pellet machine. It gives you pellets with a uniform structure and great water resistance.

Product Information

Shrimp Feed Pellet Machine

Capacity: 0.2-8 T/H

In simple terms, it’s a machine that presses your shrimp feed ingredients into water-resistant, even-sized pellets.

Unlike machines for regular livestock feed, shrimp feed needs to hold up in water for hours without falling apart – otherwise you get waste and water pollution. RICHI’s shrimp feed pellet machine comes with a three-layer conditioner. That gives the material more time to cook, improves gelatinization, and handles tricky formulas like high oil, high fiber, or low starch with ease. You get smooth, durable pellets every time.

Composition of Shrimp Feed Pellet Machine

RICHI’s machine doesn’t rely on just one part – it’s the whole system working together. So what exactly makes it up?

Variable Frequency Feeder

Stainless Steel Conditioner

Pelleting System

Drive System

Variable Frequency Feeder

A variable frequency feeder lets you adjust the feeding rate flexibly. By changing how fast the material goes in, you directly control the pelleting speed inside the shrimp feed pellet machine. The main purpose of this design is to avoid uneven feeding – uneven feed can overload the machine or leave it running empty.

Some customers use lightweight ingredients in their shrimp feed formulations, and those materials can bridge up and form arches during feeding. In practice, you can add an anti‑arching device to help the material flow more smoothly into the conditioner.

Stainless Steel Conditioner

The conditioner on RICHI shrimp feed pellet machines is made entirely of 304 stainless steel. Inside the conditioner, we use forged paddles that toss the material evenly and move it forward along the tube. Our conditioner tubes are thicker and longer than most units on the market, so the material has plenty of space to get full contact with steam. That improves cooking and gelatinisation.

It’s especially worth pointing out that RICHI uses a three‑layer conditioner. This extends the conditioning time several times over single‑layer or double‑layer designs. The feed cooks more thoroughly, and you get higher‑quality shrimp feed pellets as a result.

Pelleting System

Three main components make up the pelleting system: the pressure roller, the ring die, and the cutter.

The pressure roller has grooves on its surface that grip the material coming from the conditioner. It squeezes that material under a certain compression ratio. You can adjust this compression ratio freely – the higher the ratio, the tighter and denser the pellets become.

The ring die is a part with many small round holes. The material, after being squeezed by the roller, gets pushed out through these holes. The hole diameter in the ring die decides the final pellet diameter.

The cutter is in charge of cutting the extruded strands into individual pellets. The length of each pellet depends on the distance between the cutter blade and the die’s outer surface. You can adjust that distance freely to get the pellet length you want.

Drive System

Shrimp feed pellets need a very high compression ratio to form properly. That puts a serious load on the machine’s main shaft and tests the fatigue strength of the transmission system.

But you don’t need to worry. RICHI’s transmission system uses a high‑spec, heavy‑duty design. It comes with a Siemens motor (power range from 22 to 315kW), which gives you plenty of overload protection. Together with the variable‑frequency feeder that supplies material precisely, the whole shrimp feed pellet machine won’t clog or shut down due to momentary overload, even at high compression ratios. This is what keeps the ring die and pressure rollers running steadily and consistently, so you get uninterrupted production of shrimp feed pellets.

Advantages of RICHI Shrimp Feed Pellet Machine

Why can our shrimp feed pellet mill be exported to more than 140 countries and regions overseas? Why can it bring higher market value to customers? These are all related to its technical features and advantages.

Feeding rate, conditioning time and temperature, ring die hole size, roller compression ratio – you can adjust them all to match your needs. Need a shrimp feed pellet machine tailored to your production or a complete shrimp feed solution? RICHI’s got you.

Flexible Choices

Nobody wants to spend big money on equipment that breaks down fast. That’s not a problem here. The whole shrimp feed pellet machine is 304 stainless steel – tough and corrosion-resistant. Even the internal parts, like the forged paddles and stainless steel ring die, are extremely wear-resistant. So your machine runs steady for the long haul.

Built to Last

What’s different? We use a three-layer conditioner, and each layer has longer pipes and wider cylinders than most on the market. That helps you hit ideal levels of cooking, gelatinization, and sterilization. Plus, you can set a higher compression ratio – giving you dense, water-resistant pellets.

Cleaning

Mixing

Pelletizing

Cooling

Screening

Packaging

Cleaning

We start by feeding the raw materials into a cleaning machine. That equipment takes out dirt clods, bits of rope, metal pieces, and other foreign matter. This does two things: it protects the crusher and shrimp feed pellet machine downstream from getting damaged by hard objects, and it makes the feed cleaner and safer for the shrimp. Once the materials are clean, we send them into a grinding hopper, where they wait for the next stage.

Crushing

If you want top‑quality shrimp feed, it’s best to grind the materials twice. First, we use a dropper grinder for coarse crushing, which breaks up the fibrous structure in the ingredients. Then we put them through an ultrafine grinder for a second, finer pass, bringing the pellet size down to 80‑90 mesh – about the same fineness as flour. At that level of fineness, the powder cooks more thoroughly during conditioning, and the final pellets are much easier for the shrimp to digest.

Mixing

Mixing happens in two main stages: we blend the major ingredients first, then add the minor additives. Our mixing equipment ensures every batch has a uniform nutritional profile – you won’t end up with some pellets being more nutrient‑rich than others. That means the final pellets will have balanced nutrition throughout. Once everything is mixed thoroughly, a bucket elevator carries the blend up to a pre‑pelleting bin, where it sits ready for the pelleting step.

Pelletizing

From there, the material moves into a three‑layer conditioner via the variable‑frequency feeder, where it heats up quickly to 90‑110°C. At that temperature, the starch gelatinises fully, and any harmful bacteria get killed off effectively. After conditioning, the material goes through the ring die and pressure rollers, which squeeze it into solid strands, and then a cutter slices those strands precisely to your desired length. The finished pellets come out with a smooth surface and a dense, firm texture – drop them in water, and they hold together for a long time without falling apart.

Cooling

Since many of our customers need to store the feed or ship it elsewhere, we strongly recommend using cooling equipment right after pelleting. The cooler brings down the high temperature that builds up during the process, which helps the pellets set properly and also prevents moisture from staying trapped inside – that’s what often leads to mould and caking.

Screening

If you’re planning to sell the pellets commercially, their appearance really matters. That’s why we strongly suggest adding a screening step after cooling. A screening machine removes any broken pieces and fine powder that were produced earlier, leaving only pellets that are uniform in size and have the right hardness. That gives you a better‑looking product – and a better price for it, too.

Packaging

The last step is packaging. An automatic scale weighs out each batch of shrimp feed pellets, then a conveyor takes them to the sealing machine. During the sealing process, an operator inserts a label by hand, and the machine seals the bag automatically. This setup gives you accurate weights and fast packing, with labels placed neatly every time. Whether you’re storing, shipping, or putting them on store shelves, it makes everything a whole lot easier.

FAQ

Here are common questions from customers – maybe you’ve got the same ones. Feel free to ask more.

Why three layers in the conditioner?

→

It extends conditioning time, so material and steam mix thoroughly – better cooking and gelatinization. Compared to livestock feed, shrimp feed needs higher water resistance, and this helps minimize pollution from feed that breaks down in water.

Can your shrimp feed pellet machine handle high-oil, high-sugar, or high-binder formulas?

→

Yes. The three-layer independent conditioner allows long, low-temperature conditioning – unlike ordinary equipment that cooks hot and fast. That protects oils and binders from heat damage (oxidation or failure). For high-oil formulas, layered temperature control and staged humidification prevent sticking, clogging, or pellet clumping, giving you uniform, full pellets.

Can you customize specs for my needs?

→

Absolutely. We support custom ring die hole sizes, variable frequency drives, body material, and even conditioning processes. Got something special in mind? Just ask. Our engineers will help.

Can you help with feed formulas?

→

Sure! We’re not a feed producer, but with over 30 years of experience and thousands of customers, we know shrimp feed formulation inside out. Have questions? Reach out – we’ll help match a suitable formula and suggest conditioning parameters (moisture, temperature, compression ratio).

What if my pellets come out uneven in size or length?

→

Possible causes: uneven feeding into the conditioner, worn rollers, misaligned cutter, or blocked ring die holes. Try these fixes:

Clean built-up material off the conditioner wall regularly for smoother flow.

Check roller wear often – replace if heavily worn.

Unclog ring die holes to prevent blockage.

Still stuck? Contact us.

What’s your shrimp feed pellet machine price?

→

A single shrimp feed pellet machine typically ranges from 7,000 to 100,000, depending on capacity, configuration, and model. Tell us your specific needs, and we’ll send a detailed quote – with the best value we can offer.
