If you have your own vineyard, you can simply stop watering a couple of weeks before the vines are harvested.
Central Asian drying

Which dryer is better
Among the species emit infrared and convective.
Dryers of the first type, although more expensive, are much better dried due to the penetration of infrared rays into vegetables, fruits and other products. There they are absorbed by the liquid, and the drying process is faster.
Convective dryers are able to dry moisture only from the surface layer of products and greatly impair the drying process.
The speed of drying of products depends on the power of the device (the more, the faster). But machines with high power have a disadvantage - they work loudly.
Air can be supplied to the trays from the bottom up (provided in low-cost models.
The downside is that the lower and upper pallets need to be changed), and evenly distributed (in devices more expensive. Here all levels get the right amount of air).
The capacity of the dryer is determined by the number of trays for drying. Usually from 3 to 8. The more pallets, the faster you will cope with drying.
It happens plastic and metal. Plastic, of course, easier and easier to carry, as well as dried better. After all, metal often heats up and only "takes away" the air from the products.
The safety of drying is the presence of the function of automatic shutdown of the device in case of overheating. It will significantly extend the service life of the unit and will not allow a fire.
Drying process using a dryer

From two kilograms of grapes you get about 450 grams of quality raisins.
The next step will be grape blanching process. To do this, add soda (5 grams) to the boiling water (liter) and drop the grapes into it for five seconds. Then rinse with cool water.
This procedure allows you to clean the berries from small deposits before the appearance of the "mesh" - this will significantly reduce the drying process.
If this method is not to your liking, there is one more. For it you need to clean the grapes, get rid of the branches and wash the berries with water. Then they need to be placed in a shallow container and slightly punctured.
Spread the berries on special trays and do not forget to change pallets every hour. After 7 hours, turn off the appliance and let it cool.
The next stage will last 8 hours, and for large grapes, another one is needed.
After the specified time, turn off the electric drier and remove the ready raisins. Although it took a lot of time, but the look of the resulting product will pleasantly surprise you.
