Soldier Fly Larvae

Pressing BSFL Oil
Overall Process Flow of Soldier Fly Larvae Oil Processing Plant
Achieving a high oil yield from BSF larvae is central to profitability.
The Guance Machinery is integrated processing lines are designed to optimize every stage, from initial preparation to final oil separation.
Larvae Reception → Washing → Cooking/Drying → Oil Pressing → Oil Purification → Meal Handling.
Each stage is meticulously integrated for a streamlined, automated workflow.
Advanced Pre-Treatment Plant
Our Soldier Fly Larvae Pre-Treatment equipment incorporate precise cooking and drying stages, meticulously controlling temperature and moisture.
This Guance Machinery is proprietary pre-treatment protocols ensure optimal moisture content, typically achieving a range of 65-70% prior to pressing.
This careful preparation ensures cell wall integrity breakage for easier oil release and enhanced efficiency.
Precision Pressing Technology (GM-BSF Series)
At the core of our saolution are Guance Machinery’s GM-BSF series twin-screw presses.
These presses feature a specialized screw profile engineered specifically for BSF larvae, distinguishing them from generic oilseed presses.
This design consistently achieves oil extraction rates upwards of 95% based on available lipid content in the larvae.
This results in a residual oil content in the defatted meal typically below 5%.
Precise temperature control during pressing, maintained within 85-95°C, protects the oil’s quality while facilitating maximum separation without compromising protein integrity in the meal.
Multi-Stage Oil Separation
Post-pressing, the crude oil undergoes a multi-stage separation.
Our equipment utilize BSFL Plate Oil Filter Machine and Disc Stack Centrifuge, followed by fine filtration, to remove solids and impurities.
This meticulous filter process delivers a clean, high-purity BSF larvae oil, suitable for various industrial applications, including feed, and biofuels.
Finished Oil Storage
Centrifuged and filter oil is transferred to finished oil tanks, ready for: Automatic bottling machine, Bulk loading, Export distribution etc.
BSFL Oil Process of Advantages
1. Robust Material Selection: All contact parts are constructed from S304 or S316L stainless steel, offering superior corrosion resistance against fattay acids.
2. Optimized Wear Resistance: High-wear parts (screw flights, cage bars) utilize specialized alloys, extending operational lifespans by up to 30% compared to standard materials.
3. Rigorous Quality Control: Every component undergoes stringent inspections to meet international industrial standards for strength and reliability.
4. Energy Efficiency: Our designs incorporate heat recovery equipment and optimized motors, reducing energy consumption by up to 35% compared to conventional lines.
Final Product
1. Crude BSFL Oil: used as a high-energy feed additive (rich in lauric acid) or biodiesel feedstock, sold to aquaculture feed mills, pet food manufacturers, and renewable energy refineries.
2. Defatted Insect Protein Meal: used as a sustainable, high-digestibility fishmeal replacement, sold to aquaculture companies, poultry farms, and premium pet food formulators.

Soldier Fly Larvae Oil Processing in FAQs
Q1: What is the oil extraction rate?
A: We achieve >95% extraction efficiency with <7% residual oil in the meal.
Q2: Does pressing damage protein?
A: No. Low-temp pressing (<95°C) preserves high protein digestibility.
Q3: Do you provide installation?
A: Yes. We offer global on-site installation, training, and turnkey designs.
