The Preserving Barrel is used to extend the spoil time on various foods and food ingredients. It requires 
Sparkpowder to function. Food placed in the Preserving Barrel has its spoil timer multiplied by 10. For example: 
Raw Meat spoils in 10 minutes, but when placed in the Preserving Barrel, the spoil timer will be increased to 100 minutes (1:40:00).
Crafting
In addition to preserving food, the Preserving Barrel can make 
Cooked Meat Jerky or 
Prime Meat Jerky. Producing Jerky in the Preserving Bin takes 36 minutes. Jerky lasts for 20 days in the Preserving Bin. Creating Jerky requires both 
Oil and Sparkpowder, in addition to the Sparkpowder required to power the appliance.
Unlike the 
Large Storage Box, the Preserving Barrel fits inside a one-wall-tall hut.
The Preserving Barrel can produce both Cooked Meat Jerky and Prime Meat Jerky simultaneously.
The formula to find how much Sparkpowder would be needed to produce X jerky, including both the recipe requirement and to keep the appliance powered for the duration, is X × 4.2 for a single type, or ×3.6 for both types concurrently, rounded up. For example, 20 meat would need 84 sparkpowder; while 20 prime and 20 regular would require 144 sparkpowder. This does not take into account spoilage, so the exact yield will be off. Factoring stack and inventory limits, the most convenient ratio is 1:1 for single-type production (stacks of meat to stacks of sparkpowder) or 2:2:3 for multi-type (cooked meat to cooked prime meat to sparkpowder).
Powering
The Preserving Barrel is powered by Sparkpowder. Placing a single Sparkpowder in the bin will keep it running for 30 minutes. For more information on spoilage and timings, see Spoilage.

Notes
- Jerky in real life must be made with raw meat in order to retain enough moisture to still be palatable, as opposed to cooked meat like in the game. Additionally, adding crude oil would likely pose serious health issues for humans if ingested.
- The description says, “Cooks Jerky Over Hours” when it’s really only 36 minutes, but this certainly refers to in-game time.
- The Oceania/Preserving Barrel is treated as a thatch structure and can be damaged by anything except non-explosive ranged attacks.
- Unlike the refrigerator the preserving barrel can store
Leech Blood and 
Ammonite Bile, however this does not increase their spoil time.
