Many people have heard of dried red dates, but they don’t know what dried red dates are. Dried red dates are actually made of dried red dates, that is, dried red dates. They are just used to make delicacies and snacks. It becomes dried red dates, and many people don’t know how to make dried red dates, because in many places, red dates are not produced. Only Xinjiang has the most red dates. People in Xinjiang also prefer to eat red dates. So below we Let’s take a look at how to make dried red dates.

Dried red dates can be processed in two ways: natural sun drying and artificial drying.

(1) Sun-drying method

1. Process flow

Raw materials → quality inspection → sun-drying → turning → impurity removal → finished product

You should choose varieties with thin skin, thick and dense meat, high sugar content and small core. Generally, red dates only need to be selected before being dried without any other processing. If first blanched in boiling water for 5 to 10 minutes, cooled immediately and then spread out to dry, the quality of the dried product can be improved. In the sun-drying method, a wooden frame is usually built in the open space of the jujube garden, with a reed mat spread on top, and the dates are spread on the mat. When drying during the day, use a stick to turn the dates. At night, harvest the dates into piles and cover them with reed mats to prevent them from getting wet with dew. If it rains during the day, cover it to prevent the dates from rotting. After being exposed to the sun for 5 to 6 days, jujubes can be made.

(2) Artificial drying method

1. Process flow

Raw materials → quality inspection → blanching → baking → ventilation → emptying drawer → Grading→Packaging→Finished Products

2. Instructions on operating points

(1) Raw materials: Processed varieties are required, such as Ruoqiang dates, Po dates, Leling dates, etc.

(2) Quality inspection: Pick out injured, rotten, diseased and insect-prone dates.

(3) Blanching: Blanch the dates in a pot of boiling water, remove and drain, in order to reduce oxidation.

(4) Preheating: Gradually heat up to prepare for large amounts of water to evaporate. After the product temperature reaches 55-60℃, keep it for 6-10 hours. After loading the dates, close the ventilation window; when the temperature of the dates reaches 35-40℃, it will feel slightly hot. After 7-8 hours, the jujube body will become soft when you press it hard. Wrinkles appear; when the date temperature reaches 45-48°C, a layer of small water droplets will appear on the surface of the dates.

(5) Evaporation: Evaporate a large amount of free water inside the dates. At this time, the firepower must be increased to reach 68-70°C in the drying room within 8-12 hours, but avoid exceeding 70°C. . It must be above 60℃ to facilitate large-scale evaporation of water. Pay attention to ventilation and dehumidification, and open the windows 5 to 10 times during each production shift to let out air. After ventilation and moisture removal, the air inlet and exhaust openings must be closed to quickly increase the indoor temperature so that water can continue to evaporate. When wrinkles appear on the surface of the jujube fruit, it means the dryness is normal. But be careful not to use too much heat in the later stage, otherwise the dates will be easily scorched or the dates will be dry and wet evenly. At this time, the positions of the baking trays must also be changed and shaken continuously to make the dates on each baking tray have a uniform temperature.

(6) Drying: When the temperature inside the dates is uniform, this stage of work can be completed within 6 hours. Because there is not much moisture in the jujube at the later stage, special attention should be paid to the even heat and not to excessive heat. 50℃ is the best. At this time, the relative humidity has also dropped. If it is higher than 60%, it can be slightly dehumidified. As the moisture in the dates gradually becomes balanced, the purpose of drying is achieved. Pay attention to unloading the dried samples in time.

(7) Cooling: The baked dates must be ventilated and heat dissipated, and can be piled up after cooling
