|---|---|
Karvil Machinery recently delivered a complete, turnkey powder processing solution to a prominent food ingredient manufacturer in France. Designed specifically for blending Isomalt (Crystalline Sugar) and Inulin, this production line meets strict European food safety standards.
The Challenge: Isomalt is hygroscopic and fragile, while Inulin is a fine powder. The challenge was to mix them intimately without destroying the crystal structure of the Isomalt, while ensuring the equipment is easy to clean to prevent cross-contamination.
The Solution: Our engineers designed a full SS304 line featuring a 1000L Ribbon Blender with Variable Frequency Drive (VFD) and U-shaped Screw Conveyors. This configuration allows for gentle mixing at low speeds (protecting the crystals) and easy access for daily cleaning.
The WLLDH-1000 is engineered for precision food processing:
- Siemens Motor & VFD Control: Features a 7.5kW Siemens Beide Motor with adjustable speed (0-46 r/min). The VFD allows gentle mixing to protect fragile materials like Isomalt crystals.
- GMP Sanitary Design: Constructed entirely of Food Grade SS304. The interior is Mirror Polished (Ra < 0.4µm) to eliminate dead corners and ensure easy cleaning.
- Leak-Proof Sealing: Equipped with durable PTFE Packing Seals and a sanitary DN150 Manual Butterfly Valve for quick, residue-free discharge.
To automate the workflow, the line connects via two stainless steel screw conveyors (2.2m for feeding and 3m for discharge).
- Easy-Clean Design: Unlike tubular conveyors which are hard to clean, our U-Shape design comes with a fully openable cover. This is critical for sticky or sugar-based materials, allowing operators to pressure wash or wipe down the screw blades easily.
- Full SS304: From the screw flight to the casing, every part contacting the product is stainless steel 304.
The process concludes with the LN-H2560-P Automatic Weighing and Packing Machine.
- Inner Bucket Weighing: This system weighs the powder in an internal hopper before dropping it into the bag, ensuring high accuracy and speed.
- Sewing Sealing System: Designed for woven or kraft paper bags, the integrated industrial sewing head provides a strong, secure closure suitable for transport and storage.

F.A.Q.
A: No, it will not. We specifically designed this line with a 7.5kW Siemens Beide Motor and a Variable Frequency Drive (VFD). This allows you to adjust the mixing speed from 0 to 46 r/min. By running at a lower RPM, the ribbon blender provides a gentle kneading action that ensures a homogeneous mix without damaging the crystal structure of sensitive ingredients like Isomalt or sugar.
A: Hygiene and maintenance. For food powders—especially sticky ones like sugar or inulin—cleaning is critical.
Unlike tubular conveyors which are difficult to clean inside, our U-Shape Screw Conveyors feature a fully openable cover. Your operators can easily open the lid to wash down the screw blades and casing, ensuring 100% GMP compliance and preventing cross-contamination.
A: Absolutely. Every part that touches your product is made of high-quality Stainless Steel 304.
Interior: Treated with a Mirror Polish (Ra < 0.4µm) to prevent powder adherence.
Sealing: We use food-grade PTFE packing seals (Teflon) which are non-toxic and durable.
No Dead Corners: The design eliminates gaps where bacteria could grow.
A: Yes. The included LN-H2560-P Automatic Packing Machine is versatile. It uses an inner bucket weighing system for high accuracy. While it is optimized for 25kg bags (common for industrial food additives), the bag clamp and sewing system can be adjusted for woven bags, kraft paper bags, or plastic sacks.
A: Yes, Karvil Machinery customizes the electrical components for every client. Whether you are in Europe, the USA, or Asia, we will configure the Siemens motor and control panel to match your local voltage and frequency requirements perfectly.
A: We invite you to a video inspection or a live visit. For this specific line (French Project), we performed a full dry-run test: assembling the feeder, mixer, and packer together to simulate the actual production flow. We only ship after the system runs smoothly for consecutive hours.
