There are multiple companies that provide Tech, it depends on scale and speed. A good place to start would be with Scott Pek (http://www.scottpec.com/dryingfermentation-rooms.html) for a room/traditional style high volume system. Another option is an inline or cabinet system from CDS (https://www.dryer.com/dryer-models#KlamathK2 is an example of one of their cabinet systems. There are a lot of different options, what is the volume, what speed and how variable of types of product, etc. Good Luck!

Cabinet dryer, for small scale and traditional industry, although it has weaknesses but still the cheapest way

First you need to determine which product type you are going to dry accordingly.
drying types are available in many different variations. if you are going to design the dryer, you will need very different equations. not knowing the product features.
