Stainless Steel Lab Scale Ribbon Blender Small Batch Powder Mixing Machine Durable Construction

The lab scale ribbon blender brings pilot-plant precision to the benchtop. Using the smallest WLDH trough at 100L, it is ideal for R&D formulation trials, small-batch cosmetic and pharmaceutical blends, and food development work where repeated small formulas must be mixed reproducibly and cleaned quickly. The double-ribbon action keeps particle size intact and prevents segregation of fine powders, so the results you obtain at laboratory scale translate reliably when you scale up to the larger WLDH models. Because it shares the same geometry and mixing principle as the production units, method transfer from lab to plant becomes predictable.

Every WLDH ribbon mixer consists of a horizontal trough, a spiral agitating blade and a transmission unit. The spiral blade is generally made in two or three layers: the outer ribbon gathers material from both sides toward the centre, while the inner ribbon conveys it from the centre back to the two sides, so the two streams form a continuous convection mixing action. Because the trough can be manufactured with a circular section and fitted with a jacket, the same machine can also be used for reaction and drying when required.

• 100L Laboratory Trough: A compact stainless steel trough sized for formulation trials and small-batch work on a bench or in a small R&D room.
• Reproducible Small Batches: Consistent 30-50 kg blending cycles make it easy to repeat trials and compare formulations with confidence.
• Scale-Up Confidence: Identical double-ribbon geometry to the larger WLDH models means lab results transfer predictably to pilot and production.
• Gentle on Particles: The folding convection action preserves particle shape and avoids the attrition caused by high-shear laboratory mixers.
• Fast Changeover: A crevice-free interior and quick-clean discharge allow several different formulas to be run in a single session.
• Research-Friendly Options: Customized voltage and optional jacketed construction support drying, heating or cooling trials during development.

The lab scale ribbon blender is used for cosmetic and personal-care R&D, pharmaceutical formulation trials, nutraceutical prototypes, food and flavour development, and specialty chemical research. It is also used in quality-control laboratories to verify that a scaled blend matches the production specification.

All models share stainless steel contact parts and a gentle convection action, so they are equally suited to viscous or cohesive powders and to blending liquid and paste materials into dry powders. The WLDH range is a reliable choice for food, pharmaceutical, nutraceutical, chemical, feed and new-material industries.

Changzhou Xiaoli Drying Equipment Co., Ltd. is a manufacturer of industrial drying, grinding, mixing, granulating and packaging machines applied in the food, pharmaceutical, nutraceutical and chemical industries. Established in 2014 and exporting more than 80% of its output to overseas markets, the company designs every machine around the principle of building touching products with the spirit of craftsmen. With in-house engineering, strict quality control and responsive after-sales service, our team helps customers select, install and maintain the right ribbon mixer for their process.

We offer full customization of capacity, voltage, jacket and discharge type, together with documentation and spare parts support. Our engineers are glad to advise on the correct WLDH model, recommend the optimal fill level and mixing time, and provide layout drawings for your production line before shipment.

• What is the capacity of the lab scale ribbon blender? The lab model uses the 100L WLDH trough, giving a working batch of 30-50 kg, which suits formulation trials and small pilot runs.
• Will my lab results match production? Yes. Because the lab unit shares the same double-ribbon geometry as the larger WLDH models, mixing behaviour and uniformity scale up predictably.
• Can it mix delicate powders? The gentle folding action preserves particle size and shape, making it suitable for friable, heat-sensitive and fine powders.
• Is it easy to clean between formulas? A smooth, crevice-free stainless steel interior and a quick-clean discharge valve allow fast changeover between different recipes.
• What are the ordering details? The minimum order quantity is 1 set, delivery is normally about 30 working days, and the machine carries a 12-month warranty.
