Shrimp are lean and dry quickly once cooked. They come back nicely in hot dishes like pasta, fried rice and chowder, although the texture is softer than fresh.
Seafood is the category where sanitation matters most. Utah State Extension lists raw seafood as unsafe for home freeze-drying and gives 145 °F as the cooking target.
Prep and loading
- Cook shrimp until opaque and 145 °F. Peel and devein.
- Halve large shrimp lengthwise so no piece is thicker than about ½ inch.
- Chill, then spread in a single layer.
- Clean and sanitize the trays well afterward.
How to tell it’s done
- Shrimp are hard and light; the thickest part is dry when broken.
Not sure? The weight check compares two weighings and the expected dry weight for shrimp.
Problems and fixes
Fishy smell in the machine
Wipe the chamber and gasket after seafood batches and leave the door open to air.
Rehydrating and storing
Rehydrate: Cold water in the fridge 15 minutes, or straight into hot soup. By weight, 100 g of dried shrimp takes back about 341 g of water to return to fresh weight; the rehydration calculator does any amount.
Store: Mylar with oxygen absorbers.
Ways to use it
- Fried rice
- Pasta
- Chowder
- Camping meals
How much fits per batch
At a normal single layer, shrimp load at roughly 2.2 lb of fresh food per square foot of tray. That works out to:
| Machine | Fresh per batch | Dried per batch |
|---|---|---|
| Harvest Right Countertop 360 | 5.5 lb | 1.24 lb |
| Harvest Right Small | 6.6 lb | 1.50 lb |
| Harvest Right Medium | 10.3 lb | 2.34 lb |
| Harvest Right Large | 16.9 lb | 3.84 lb |
| Harvest Right X-Large | 34.4 lb | 7.80 lb |
