Combined Drying and Conveying in One Compact System

The ZilliVibro Spiral Elevator has been developed for process lines where material handling is not just about moving product from one level to another. In sea salt, chemical granules, crystalline products, and free-flowing powders, the way the product is lifted, dried, cooled, drained, and transferred can directly affect consistency, flow behaviour, moisture level, and final product quality.

After washing, sea salt often carries surface moisture and requires controlled handling before it reaches the next stage of production. A standard conveyor may move the product, but it does not support the process. A separate dryer may reduce moisture, but it increases floor space, transfer points, power demand, cleaning time, and maintenance.

​

The ZilliVibro Spiral Elevator brings these stages together in one compact vertical system.

Using controlled vibratory movement, the product travels gently along a spiral conveying path while process air can be introduced to assist with drying, cooling, or moisture reduction. This gives the material more residence time than a simple inclined conveyor, while still maintaining a continuous and controlled product flow.

For sea salt production, this is especially valuable. Salt is abrasive, moisture-sensitive, and demanding on equipment, particularly after washing or dewatering. The machine can be manufactured in stainless steel and designed with hygiene, clean ability, corrosion resistance, and long service life in mind, making it suitable for food-grade salt, chemical-grade salt, and other granular or crystalline materials.

​

Unlike conventional systems that require separate conveying and drying equipment, the ZilliVibro Spiral Elevator reduces the number of machines in the process line. Fewer transfer points mean less product loss, less contamination risk, reduced mechanical complexity, and a cleaner production layout.

Its vertical design also makes it ideal for factories where floor space is limited. Instead of using long horizontal conveyors or multiple handling stages, the product is elevated within a compact footprint while still allowing useful processing to take place during transfer.
