How to make raisins/dry grapes at home:

  Grape and raisins are common in supermarkets, so how do we make raisins at home? First of all, we need to select fresh grapes with thin skin, soft flesh, and suitable maturity. Wash them with water. We can add some flour to the water to better clean them. Cut off the moldy and discolored unqualified fruit particles. Put the grapes on a plate and put them on the balcony where they can be exposed to the sun at most. About ten days or so, if the upper part is already dry, we can turn the grapes over and continue to dry for ten days, and then pile bunches of grapes together and evenly dry for half a month.
  There is another method here, which is to use the air-drying method, which often appears in Xinjiang, China. Soak the grapes in saltwater and blanch them with boiling water to accelerate the loss of moisture inside the grapes. Let the grapes be allowed to dry naturally for a few days. Do not pursue sun exposure. In the morning and evening, you can use a hairdryer to dry raisins, and it will be completed after repeated 20 days. Dried raisins are extremely beautiful in appearance, crystal clear.

How to making raisins/dehydrate Grapes in large quantities with a dryer:

  If we have a large of grapes, how do we dry them in a short time? Yes! We need a dehydrator to make them.
  • Step one: wash the prepared grapes and pick out the bad ones. 
  • Step two: add water to the pot and boil, put the grapes in, and boil for 30 seconds, then remove the grapes on a plate. This step is to dry out the grapes faster. 
  • Step three: put these grapes into the bowl which has to add two teaspoons of citric acid and stir them for 10 minutes to improve our raisins’ quality. 
  • Step four: drain the grapes and place them on the tray of the dehydrator layer by layer. 
  • Step five: set the dryer to 120 degrees Celsius and turn on the dryer. 
  • Step six: check if the grapes are completely dry after 24 hours of dehydration. 
  • Step seven: take the finished raisins out of the dryer and let them air dry for 2 hours, then the delicious raisins are finished. And we can store them in a sealed instrument to extend the shelf life. 
  Here are some advantages of dryer-made raisins over our handmade ones: Firstly, the machine is made cleaner. During exposure and air drying, dust may accumulate on the surface of the grapes. Secondly, the machine can increase the amount of production, and the speed of the production is quicker, the success rate is higher than manual making.
