Do you have access to a lyophilizer? 

Unfortunately, No, I don't have access to freeze-drier. is it a necessary? 

You need some form of simple rotary dryer, depending on the moisture level. Sun drying could even be a possibility depending on the nature of your original material. Don't forget not to heat/dry too much as heat damage amino acids, I suppose you want to use it as a protein feedstuff? Interestingly you might even grade the heating temperature and time of exposure as potential factors impacting the quality of your final material. If too wet, you may add some bran to damping the moisture. If you are specifying some high level of quality, perhaps you need to add some antioxidants to deter spoilage processes. Moreover try to study how to keep moulds out of the material to obviate mycotoxin issues. Apart from these I think you are one of the smart minds we need for the sustainable future we are dreaming about. Good luck.

dear David O. Akinde,

thank you for your favor. 

Hi,

I think I may share this experience with you.

If cooking oil is not a problem to your product (ie feed) an power is not available as it is the case in Nigeria where I work, you can try this option

1- You may dip fry your locusts whole in olive oil or any light oil to reduce moisture.

2- Place the fried locusts on absorbent paper to drain the oil

3- Sun dry the locusts carefully to become crispy

4- Grind the dried locusts with a genrator-powered milling machine

5- Sun dry the powder to the level you want and store it in a dry container

I hope this long and cumbersome process will help where there are no power and kits

Dear Sako Mirzaie an easy way is to keep your stuff in a desiccator with well dried slica, though it takes time but it would not let the most of the material wasted.
