Probat Neptune

the verdict

the neptune is probat's heavy production roaster, handling 60 to 600 kg per batch. this is for contract roasters, large distributors, or facilities running continuous multi-shift schedules. fully automated gas drum system engineered around repeatability at scale. the machine's strength is maintaining tight control across massive batch sizes, which most roasters never deal with. drum design and multi-point temperature sensing keep development even when you're roasting hundreds of kilos at once. automation and profiling systems are built to prevent drift across thousands of batches. trade-offs are obvious: this is a specialized piece of equipment with a matching price tag, footprint, and operational complexity. you need the infrastructure to support it: proper ventilation, gas supply, skilled operators, and volume that justifies the investment. if you're producing multiple tons per day and consistency is non-negotiable, the neptune makes sense. anything smaller and you're overbuying.
