Spiral elevators convey bulk material upwards to accommodate with space constraints and production line arrangement, but they are also used to process the product during the conveying.
Holes can be incorporated into the spiral tower to force air out and across the product, and jacketed flights can provide indirect heat transfer with steam, oil or water.
Carrier spiral elevators are available in large sizes (more than 3m diameter and 15m height), for light or heavy duty, high temperature, sanitary design, and can be enclosed to protect the product environment or provide operator safety.
Retention time can be adjustable to control even further the finished product conditions.
Spiral elevators are typically used for the processing of rubbers, plastics and other polymers, as well as in the food and pharmaceutical industries.

Carrier is a leader in engineering, design and manufacturing of vibrating equipment for bulk material processing. Since 1950, it has been known internationally as the pioneer in vibration technology, founded on a reputation for solving unique processing challenges.
Our main products include conveyors, feeders, screeners and dewatering screeners, fluid bed dryers and coolers, spiral dryers, and shakeouts.
All our equipment relies on vibrating technology, which applies harmonic motion to handle and process your product without degradation. Our designs are also known for their low energy consumption, minimal maintenance and long life expectancy.
We offer a custom design approach starting from your process, and adapt to your specific needs and constraints. This is why we can serve a large range of industries, like recycling, wood, chemicals, rubber, food, foundry, metals, mining, glass, biomass, plastics, and more.
We know more than anyone that each process is unique, and each product behaves differently in different conditions. This is why we also propose and recommend testing of your product in our lab facilities so we can determine the optimal equipment sizing, depending on intended capacity, and give a process guarantee to the customer.
We guarantee a worldwide coverage, with production sites always close to the end user, plus a network of local sales agents.
