Cut your tomatoes in half when you're ready to use them. The seeds must be removed at this point. The next step is to score the skin lengthwise with a knife. Open-side-up, place tomatoes in your dehydrator with 1-2 inches of space between each rack for good ventilation and sprinkle salt on the open side of the tomatoes. Place in a dehydrator and dry for 6-8 hours at 135-140 degrees F. The exact time will vary according to your location's humidity and the ripeness of your tomatoes.

How to preserve tomatoes in the fridge
Knowing tips for how to preserve tomatoes in freezer or fridge could be really useful for all housewives. You can keep unripe tomatoes on the counter for a few days until they are ready to use. (When they're aromatic and yield slightly to the touch, you'll know they're ready.) Once they're ripe, you can either eat them or put them in the fridge to keep them fresh for longer. If you keep a ripe tomato in the fridge, it will last around two weeks. To the best of my knowledge, the answer to this question is "yes." Tomatoes can be stored in the refrigerator, but the freshness of the fruit should be taken into account before storing them. Unripe tomatoes taste terrible, and nobody wants to eat a mealy, bland one. 
In the event that you store unripe tomatoes in the refrigerator, they will remain that way and will never reach their full potential. Refrigerate or eat a perfectly ripe tomato if you can get your hands on one. Remember that overripe tomatoes can be used in sauces, relishes, chutneys, and other dishes as long as you store them in the refrigerator to prevent them from spoiling. Let your tomatoes come to room temperature before eating them, even if you plan to keep them in the fridge. The best flavor comes from tomatoes that are at room temperature. Storing Slicings of Tomatoes There is a way to extend the life of a tomato that has been cut into, even if the skin is intact, so long as you keep it whole for storage. Wrap the uncut side loosely in plastic wrap and place it over the cut side. Refrigerate the tomato, cut side down, on a small platter. Sliced tomatoes can be kept for a few days in this manner. 
How to preserve tomatoes in oil
If you know how to keep and preserve tomatoes in any other materials other than can or fridge; it can give you a leg up. The oil is one of those items that can be used for keeping tomatoes. Ingredients Tomatoes ( cherry tomatoes or any other kinds) Oil made from olives Salt (or your favorite spice) Garlic in the clove (optional) Rosemary bushes that are bursting with life (optional) Instructions Turn the oven temperature up to 400 degrees. A light coating of olive oil should be drizzled over the tomatoes after they have been laid out in a single layer on a baking sheet. 
Salt should be sprinkled on the tomatoes. Roast the tomatoes in the oven for twenty minutes, or until the skins have split and the tomatoes have released their aroma while still retaining enough structure to stay together. Place the tomatoes in a glass jar and, if you so choose, add the garlic and rosemary to the jar as well. Keep a headspace of one inch at the very top of the jar. Fill the jar all the way to the very top with olive oil. Inserting a butter knife on the inside of the jar, all the way around the tomatoes, will assist in releasing any air bubbles that have become trapped inside. Again, at this point, you want to make sure that all of the tomatoes are covered in olive oil, and you should add more oil if necessary. Before putting the jars away for an extended period of time in the refrigerator, make sure to give them a label and a lid first.
