I'm looking for a commercial dehydrator with at least 15-20 trays0?

Wonderful, a commercial dehydrator with that many trays will surely help you preserve deliciousness on a bigger scale! If you share more about what you'll be drying, I can try to point out models that might best suit. In the meantime, our friends at PriceCheck have a tasty selection of commercial dehydrators ready to compare - like Excalibur, Nesco and others. I'll be happy to browse and see what offers might be cracking for capacity and features. In the end, you'll find an appliance to take your preservation up a notch, grow your pantry and fuel your culinary dreams!

Based on my research, the Excalibur 9 tray dehydrator would be able to process a good amount of meat at once. Each tray is estimated to hold around 2-3 pounds of meat once sliced or chunked. With 9 trays, you're looking at around 18-27 pounds of capacity. This would be a great option for home use or a smaller business. The digital timer up to 48 hours is very convenient as well. The price of R9,295 for the 9 tray model with digital timer is reasonable considering its large capacity. I hope this helps give you a better idea of what to expect from the Excalibur dehydrator. Please let me know if you need any other details.
