Green Beans Drying Process/Dehydrate Green Bean In a Dehydrator

   Green bean is a vegetable that is abundant in summer. It contains various vitamins and minerals. The tender bean pods are fleshy and crispy when fried. They can also be blanched or marinated. The pods are long and like tubes and it is crisp and soft. There are two common types of white beans and green beans.


  Dried Green beans, also called dehydrated green beans, usually use cowpeas and broad kidney beans as raw materials. After being cooked at high temperature, they are dried in the sun or machine. After drying, the finished product is black and fragile. Adopt air energy bean drying equipment, use low-temperature drying and slow dehydration process, so that the material dehydration is kept uniform and the tissue damage is small. 

 What is the drying process of green beans/Dehydrate green bean in a dehydrator 

  The green beans that have been dried by the bean dryer can be used as dried vegetables and are also very delicious. Now the engineer from Baixin Company will focus on and explain the process of drying green beans through an air source heat pump in the following.  
The first step: picking beans. Dried beans should be fresh, tender and firm-textured, and insect-free. This kind of fresh dried beans is the best, with a strong fragrance and good taste.
Choose fresh and tender beans that are harvested on the same day and are light green, long, straight, and well-proportioned, without whitening or softening, and the seeds are not exposed. Spread out to avoid heat. Use tap water to wash away the sediment and other impurities on the raw materials. Harvest on the same day and process on the same day.
Step 2: After cleaning the green beans, blanch them in boiling water, drain the water, and put them into the stainless steel trays. Pay attention to the neat layout, and the thickness of the laying should be within 3 cm. 
Step 3: Push the tray containing the beans into the drying room of the heat pump dryer, close the door, set the host operating program, and set the operating time of the drying equipment according to your own drying needs. Temperature, humidity, and other parameters, and then start the equipment.
The first stage: put the cooled beans with trays into the drying chamber quickly, and place them evenly at a temperature of 60-65°C and a time of 40-50 minutes 
The second stage: the temperature is 65-70℃, and the time is 30 minutes; The third stage: the temperature is 70-80℃ until dried, the time is generally about 3 hours. The interval time between two dryings is 1-2 hours. During the drying process, it adopts the 360 hot air circulation method, and every corner of the drying room has heat to reach, and there will be no phenomenon of non-drying of materials in a certain corner.
Step 4: After the running time is reached, the host machine will shut down automatically. After the beans are simmered in the drying room for another hour, the material truck is pushed out, and the whole beans are dried.

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.
