This project focuses on shrimp feed pelleting machines in the Philippines. A shrimp hatchery and grow-out farm in Negros Occidental, Philippines, was producing 2,000 tons of black tiger shrimp (Penaeus monodon) annually. The farm had its own feed mill, producing feed for its post-larvae (PL) nurseries and grow-out ponds. The challenge was water stability. Shrimp feed must stay intact in water for 2-3 hours.
This project focuses on shrimp feed pelleting machines in the Philippines. A shrimp hatchery and grow-out farm in Negros Occidental, Philippines, was producing 2,000 tons of black tiger shrimp (Penaeus monodon) annually. The farm had its own feed mill, producing feed for its post-larvae (PL) nurseries and grow-out ponds. The challenge was water stability. Shrimp feed must stay intact in water for 2-3 hours.
Their existing single-shaft paddle mixer and simple pellet mill couldn't achieve the necessary water stability. Pellets disintegrated within 30-40 minutes, leading to poor feed conversion and water quality issues. The farm manager decided to invest in a specialized shrimp feed pelleting machine with a triple-conditioning system.
The farm manager explained the situation: "Black tiger shrimp are sensitive to water quality. If feed breaks apart, it pollutes the ponds. We needed a pelleting machine that could produce water-stable pellets that last 2-3 hours. The triple conditioner is the key."
The farm had a small shrimp feed production line with a hammer mill, mixer, and an old pellet mill. They decided to upgrade to a specialized shrimp feed pelleting machine.
Name:
shrimp feed pelleting machine
Country:
Philippines
Date:
2025
Capacity:
0.6-0.8 tons/hour
Model:
SZLH320
Main Motor Power:
37kW
Raw Materials:
Fish meal, Soybean meal, Wheat flour
Pellet diameter:
1.5-2.0mm
From the pellet mill table, the SZLH320 (37kW) was selected. Why this model?
The farm manager chose the SZLH320 shrimp feed pellet machine with the triple-conditioning system – the most advanced configuration for shrimp feed.
The Philippines is a major shrimp producer. The farm uses:
Pellet sizes by shrimp stage:
Target water stability: 2-3 hours
Target protein: 38-40%
Target fat: 6-8%
Target moisture after pelleting: 10-11%
The SZLH320 arrived at the Port of Manila – the Philippines' main port.
Shipping time from Qingdao to Manila is about 7-10 days. The machine was packed in a 20-foot container with:
Customs clearance in Manila took about 5 days. Total landed cost was about 20% higher than the FOB price.
Installation took three weeks. The old pellet mill was moved to a backup location. The new SZLH320 was positioned on a reinforced concrete foundation (200mm thick). The electrical hookup required 380V, 60Hz three-phase (Philippines uses 60Hz). RICHI provided a 60Hz-compatible motor. The 37kW motor required a 100-amp breaker.
The first test run was with juvenile shrimp formula (2.0mm die). The triple conditioner added steam in three stages:
The pellet mill ran smoothly at 0.7 tons/hour. Water stability test: 2.5 hours. Pellet durability (PDI) was 95% – excellent for shrimp feed.
After six months of operation, the farm manager documented the following results:
Before (old simple pellet mill – no triple conditioning):
After (SZLH320 with triple conditioning):
Production output:
Economic impact:
FCR improvement: 0.2 points = 0.2kg less feed per kg of shrimp
Annual shrimp production: 2,000 tons
Feed saved: 2,000 × 0.2 = 400 tons/year
Feed cost: $1,200/ton
Annual saving: $480,000 (€440,000)
The machine cost delivered approximately $45,000 USD (about €41,000). Payback period was about 1-2 months based on FCR improvement alone.
"Shrimp feed must be water-stable. Our old pellets disintegrated in 30 minutes. The shrimp couldn't eat them in time. The ponds got dirty.
The SZLH320 with triple conditioning changed everything. Three stages of steam – 60°C, 75°C, then 85°C. The starch is fully gelatinized. The pellets last 2.5 hours in water.
Our FCR dropped from 1.9 to 1.7. That's 400 tons less feed per year. The shrimp are healthier – survival up from 70% to 82%.
Would I recommend this machine? Yes. For any shrimp farm, triple conditioning is essential for water stability."
Stage 1 (60°C, 15% moisture): Initial hydration – softens particles
Stage 2 (75°C, 17% moisture): Starch gelatinization begins – binding action
Stage 3 (85°C, 18% moisture): Complete gelatinization – maximum binding
The result is pellets that withstand 2-3 hours in water without disintegration.
| Shrimp Stage | Pellet Size | Die Thickness |
|---|---|---|
| Post-larvae (PL10-PL20) | 1.5mm | 15mm |
| Juvenile (PL20-PL40) | 2.0mm | 20mm |
| Sub-adult (PL40+) | 2.5mm | 25mm |
Compression ratio: 1:10 for all.
The SZLH350 consistently achieves 95% intact after 2.5 hours.
Feed per ton of shrimp (old): 1.9 tons
Feed per ton of shrimp (new): 1.7 tons
Saving per ton: 0.2 tons
Annual shrimp production: 2,000 tons
Total feed saved: 400 tons
Value at $1,200/ton: $480,000 (€440,000)
The triple-conditioning machine paid for itself in two months.
The SZLH320 feed pellet machine shipped from Qingdao to Port of Manila, Philippines.
Shipping time from Qingdao to Manila is about 7-10 days. The route goes through the South China Sea.
The machine was packed in a 20-foot container. Customs clearance in Manila took about 5 days. Total landed cost was about 20% higher than the FOB price.
The truck transport from Manila to Negros Occidental required a ferry – total time about 24 hours.
The SZLH320 shrimp feed pelleting machine with triple conditioning produces water-stable pellets that last 2.5 hours. The three stages of steam (60°C → 75°C → 85°C) fully gelatinize the starch. Small dies (1.5mm, 2.0mm, 2.5mm) ensure correct sizing for each shrimp stage.
Triple conditioning = water stability = better FCR = higher profits.
