If you don't have electricity running to your yurt, it may be hard to keep a freezer going. For long-term storage of your perishable foodstuffs, you'll need something that makes use of cold weather, can endure short hot spells, and keeps your food accessible.
This clever man that some people on reddit think lives in northern China uses a clever, multi-stage process to build a functional deep freeze. What's necessary is both ice and carefully arranged hot water.
I don't know who he is, but making things with ice and hot water is appearently his thing. Here's a video of him making a smaller ice chest with functional hinges.
