Cherries are bright in color, crystal clear and beautiful, red as agate, yellow as gelatin, and the fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements. Although its fruit is as small as a pearl, its color is red and bright and smooth, and it is exquisite like an agate gemstone. It tastes sweet and slightly sour. It can be eaten fresh, pickled or used as an embellishment in other dishes and is very popular.

When the cherries are ripe, afraid of heavy rain and strong winds, the fallen cherries will rot quickly, and there is no other way out except throw them away. The shelf life of cherries is only about one to two days. If you don’t eat them, they will soon spoil, so they must be dried and stored in the form of dried fruits for a long time.

Traditional cherry drying method

Due to the short ripening period of cherries, they are concentrated on the market and cannot be stored well, which limits their sales and large-scale production and planting. The traditional drying method needs to be dried in the open air. They are easily contaminated by dust and flies. The temperature and humidity of the drying cannot be controlled. If it is rainy, it is very likely to cause the dried fruit to become moldy.

The traditional drying and electric heating of cherries have been replaced by heat pump dryers. The intelligent control system of heat pump drying technology solves the above drying problems and makes the cherry drying quality better. The following editor will introduce the cherry drying process.

Cherry processing steps

1. Pick cherries

Choose the varieties with bright skin color, short stalk, small nucleus, uniform fruit size, sweet taste, and small juice. Remove mildew and immature fruits, then remove the stalks, put them in a basket and wash them with running water 2-3 times in a sink or basin , Remove impurities, remove the stalk by hand;

2. Soak alkali rinse

In order to shorten the drying time, it is best to blanch the cherries in 0.2-0.3% boiling lye for a while, then rinse them in clean water to remove the lye, and then put them in the basket for 5-10 minutes to drain the water;

3. Cherry drying process

Step 1. Set the temperature to 60°C and wait for the cherries to drain some water.

Step 2: Set the temperature to 65-70°C, and set the time to 12-15 hours.

The moisture content of dried cherries can be controlled at about 18%.

4.Drying and softening: The sugar content of cherries directly determines the temperature setting of the cherries in the later stage, so the fruit trays with different sugar content should choose the appropriate later temperature, and the later drying and consolidation stage adopts the method of lowering the temperature, and the temperature is controlled at 58 ℃ is enough, in order to achieve the water balance inside and outside the fruit, the texture is soft, after drying, pour the dried cherries into a wooden box and let them soften for 2-3 days.
