There is not a specific amount of time that they need to stay in the ice other than that they need to cool down all the way. After the ice bath, they will be going into the freezer, and you do not want to store warm green beans in the freezer. It is not a good idea to store any kind of hot food in the freezer, and it should be left to cool down and reach room temperature before freezing.
Once inside the freezer, the difference in heat between the inside and the outside of the container will be so much that the food will start sweating. Condensation will form and this can damage the food you are trying to preserve. In other words, you will end up doing the opposite what do you want. So, you want to wait until the green beans cool down all the way and reach at least room temperature before taking them out of the ice bath and putting them into a freezer safe container.
You can store the green beans in an airtight freezer safe plastic container or in a resealable plastic freezer bag. The important thing is that no matter which container you use, it needs to be freezer safe. This will ensure that the container or bag protects your vegetables from freezer burn and is airtight. There will be less chance of any leakage into or out of the container.

The best way to allow your green beans to thaw properly is to transfer them from the freezer to the fridge and allow them to naturally thaw overnight.

Blanching is scalding vegetables in boiling water or steam for a short time. It is typically followed by quick, thorough cooling in very cold or ice water.
Blanching stops enzyme actions which otherwise cause loss of flavor, color and texture. In addition, blanching removes some surface dirt and microorganisms, brightens color and helps slow vitamin losses.
It also wilts greens and softens some vegetables broccoli, asparagus and makes them easier to pack. It is critical to use the correct blanching time for the vegetable and size see table below. Under-blanching stimulates enzyme activity and thus is worse than no blanching. Over-blanching leads to partial cooking and causes loss of flavor, color, vitamins and minerals. For home freezing, the most satisfactory way to blanch all vegetables is in boiling water. General instructions for water blanching follow:.
This process also helps remove dirt and organisms on fresh produce. Blanching time is crucial because underblanching stimulates the action of enzymes, while overblanching causes vegetables to lose color, flavor and nutrients.

Please note that the following Blanching Times chart is intended as a general guide only — the actual blanching times may differ due to a number of factors. Method 1: Arrange the blanched vegetables in a single layer on a cookie sheet lined with a freezer-safe silicone baking mat or parchment paper, and put the sheet in the freezer. When the vegetables are frozen solid, transfer them to freezer-safe Ziploc bags or containers, and pop them back into the freezer for storage.
The great thing about this method is that your blanched vegetables won't fuse together in the freezer, and you'll be able to grab just a few frozen pieces whenever you like. Method 2: Divide the blanched vegetables into portions that work for your needs.
