Hi folks:

This this my first post & I'm hoping for some answers from the members. I just bought 4ea 50# bags of pinto beans. I have a large Excaliber dehydrator and wish to dry them enough to do LTS in mylar bags, oxygen absorbers and vacumm sealing. I put up hundreds of pounds of beans, rice, oatmeal,onions and other things in 2011. I bought this food from a Mormon food center so all items met the moisture requirements for LTS. The beans I just bought aren't dry enough to pack them up. When using my Excaliber, how can I tell when they are dry enough to bag up for LTS?

Thanks in advance to all who can help with your posts.


Wow! I have no idea. How do you know they aren't dry enough?

I've often put up dried beans in mylar after buying them in the grocery store and never even thought about checking the moisture levels. I like to put several different varieties of beans in 1-2 lb bags in a 1 gallon mylar bag so that I have a variety when I open it later. I do cut a hole in each of the plastic bags they come in to allow air to be expelled when I vacuum seal, but other than that, I have just put in the O2 absorber, vacuum sealed and called it good.


When I did this back in 2011, it was my understanding that beans were not to exceed 3% moisture content in order to be put up for LTS. I broke out a 4# bag of pintos a couple of months ago that were 9 years old & they were great. The Morman food bank where I got the food required their suppliers to meet a certain moisture content beause those folks are all about putting up food that will last 25-30 yeaqrs. As to what will happen if my beans have too much moisture...

!.) I don't want to take that chance without knowing about the moisture thing for sure. If the moisture isn't correct, there is a
     strong possibility the beans could spoil quickly.
2.) I heard once that after dehydrating beans, take a couple and whack them on concrete with a hammer. If they are powdery
     looking they should be good to go. Anything less than this could spell trouble.
3.) This is why I've posed the question... if I'm going to put in all of the work to do the LTS, I don't want to take a chance it will
      be all for nothing. I hope you can help me find some answers, Thanks

The hammer technique will not be gospel for me unless I hear about it or other methods on this site.

Weigh 1# of your beans out. Then put in your oven on low, 200 for 30 minutes
Re-weigh your beans and see how much was lost.

Can't find my chart at the moment, but if the beans haven't lost over about 5% weight I'd say they were already dry enough to bag.


So grateful for your reply. Please find your chart and some how get it to me if you would. It makes good sense what you've said about this, just need a few more facts?

Many thanks again
