Okay I'm pretty new to all this and this is my first post on this board.
I graduated last year from university with a cellular biology degree, and have now taken over my family's italian food business (est. 1968 by my grandfather). We produce both fresh and dry-cured meat products.
What I want to do is make a salami drying room. I have already used some information from this site regarding relays and temp controllers to start a portion of the project. There are ultra sophisticated systems that can be purchased from http://www.frigomeccanica.it/ita/pages.asp?id=47&sFullId=3.2&idMenu=2"
What these try to accomplish are all of the following:
1. Control humidity with a microprocessor that "ramps" the %rh down from (for example) 100% to 60% during the course of drying. The reason for this is so the salami doesn't dry too quickly at the beginning causing the outer portion to form a crust, sealing the inner portion and reducing further drying.
2. Control temperature with a microprocessor, similar to the humidity ramping.
3. Keeps air flowing throughout the room by using diffused air ventilation.
The only problem is that each of these rooms costs about $100 000, and we need three.
What I have done that seems to be working quite well is to buy a standard desiccant dehumidifier, and connect this to a http://www.dwyer-inst.com/Products/Product.cfm?Group_ID=141" . I am now ramping the humidity and temperature down manually. What I would like to do is use an Arduino board to control a relay that will switch on and off the dehumidifier. In this way I can automate the process.
The problem I am having isn't with the code, but with the idea of controlling a 110V dehumidifier with the arduino...the physical aspect of the whole thing. Is it even possible?
Okay that was an extremely long explanation for a small question...but there will be many more questions on this thread and I'd like to offer some sort of reward to people who help me with this...since it is for my business.
