How to dry dates?

  Dates, also known as big dates, thorn dates. Dates grow in mountainous areas, hills, or plains below 1700m above sea level.  Dates are rich in vitamin C, vitamin P, and other nutrients. Because the planting of dates is more concentrated and mature in autumn. Dates are not easy to preserve and may rot within three to five days. To better store the dates and facilitate transportation toll over the world, the dates can be dried. Let’s take a look at how to dry dates.

How to dry dates at home:

 1:Sunlight Drying

  This is the most traditional and direct way to drying dates. This method has the lowest cost and is a good way for people who don’t want to invest in electrical appliances. However, it takes a relatively long time and also depends on the weather conditions and the size of the dates, if they are particularly large date is best to cut them in half for easy drying. In the first step, fresh dates need to be washed with clean water and then wipe off the water on the surface. In the second step, remove the nucleus in the dates. There are two ways to remove the nucleus. The first is to cut the date in half and take out the nucleus directly. The second is to take out the date directly with a special nucleator, to maintain the integrity of the date. In the last step, put the pitted dates neatly on the board and take them out to dry directly. If the weather is good, dry it on the front side in a few days and then turn it on the other side. After both sides are dry, they can be stored in a sealed bag. This method of sun-dried dates should also be clear. It is best to cover the dates with a screen to prevent pollution from insects, birds, and flies.

2:Oven

  The second method is to use the household oven. This method is more suitable for household use. Making it at home is simple and time-saving. At the same time, it can control the early dryness and wetness. As long as the time is well grasped, the goal can be achieved. The steps for drying dates in the oven are the initial steps of using the sun to drying dates. The washed dates are pitted, put directly into the oven, and dried. But you need to have strict control over time, different ovens have different effects.

How to dry dates in large quantities?

  If you need to produce large quantities of dried dates, it is not enough to rely on household ovens and direct sunlight to dry them. This requires a professional dryer and ovens. A large-scale dryer or oven to produce dried dates saves time and realizes mess production.
Ⅰ  Selection of row materials. You need to choose dates that have a smooth surface, no bugs, and no rot.
Ⅱ Cut the date in half and remove the nucleus. A cutter or a seeder is needed to make a large number of dried dates.
Ⅲ Preheating and evaporation stage. The dryer needs to be pre-heated in advance to prevent the huge temperature from causing the loss of dates nutrition. The temperature needs to be raised to 65℃ during the increased phases, which takes about 8 to 10 hours, and there is litter left to evaporate the water in dates.
Ⅳ Drying and cooling stage. During the drying stage, attention should be paid to the temperature is 45℃. It takes about 6 hours. Of course, it can be changed slightly for different varieties. After cooling, you need to pay attention to ventilation.

Henan Baixin has two types of professional dates dryer.

1:The first method:date heat pump dryer

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation
  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.
  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.

2:The second method:date continuous mesh belt drying machine

Large amount of dehydration 200-5000kg/h food vegetable drying machine continuous automatic work easy operation
  Date dryer machine is a kind of continuous production drying equipment, the main heating way has electric heating, steam heating, hot air heating. Its main working principle is to spread the material evenly in the network. The material is moved in the dryer by the operation of the machine, and the hot air draws out the water vapor of the material. so as to achieve the purpose of drying.
The operation temperature is 40-120 degree centigrade. And the dry cycle is 1-5 hours.
