Why to dry beans quickly?

• Avoid mildew and prolong storage time. When the seeds are dried in the sun and the free water is almost exhausted, the life activity of the seeds is stopped, but the protoplasm structure of the embryonic cells is not destroyed and the cells have not lost their activity. If the seeds are not dried in the sun, they will breathe, consume the organic matter stored in the seeds, and maybe be produced by aerobic respiration and the reaction of substances in the environment and moldy, thus shortening the storage life of the seeds. 
• Pest control. Grain moisture drops below 8%, and the worms can’t survive.

How to dry beans at home?
There are two ways to dry beans, the microwave oven heating drying method, and the natural drying method.

1. The first microwave oven drying process steps are as follows:
2. Put the beans in a container and wash them with tap water.  Dry the beans in a filtered basket and preheat the oven to 160 degrees for 10 minutes.
3. Place the beans in the oven on a tin foil-lined baking sheet and turn them twice in 20 minutes. (According to the different types of oven baking time difference. )
4. Such as soybean golden skin crack will be baked, take out the baking tray, put in the ventilation place a little cool for a while.
5. Take the container and load it.

The second natural drying process is as follows:

1. Soak the beans in boiling water for half a minute, stirring as you soak.
2. Remove soybeans from boiling water and place them directly in cold water.
3. After pulling them out of cold water, dry them in the Sun. 
4. Store dried beans in a well-sealed container with cloves of garlic to prevent insects.

How to dry beans in large quantities?

  Soybeans are dried in a variety of ways. Generally speaking, they are dried more naturally in the sun, because the harvest season for soybeans is usually late summer or autumn when there is usually more sunny days and less rainfall, so there is a chance for them to dry naturally, however, it takes longer for soybeans to dry naturally, and the degree of drying is not completely the same. If the amount is large, plus the harvest season is overcast and rainy, you can use the heating drying method. Even the use of professional drying equipment for drying, drying speed, and drying degree is consistent, and not affected by the weather.
  The soybean drying process is not complicated, cooking out color reduction, full shape only need a few steps: 
  Before drying, you can use pot boiling water or steaming cage again, so that the soybean is soft, for the later color paves the way, and then into the drying room for drying. 

• Stage 1: set the temperature to 40 degrees and dry for 5 hours. So that most of the water out of the soybean, color, and shape of the initial shape. 
• Stage 2: Temperature rises to 55 degrees, drying for 5 hours. Raise the temperature just a little bit, drain the water again. 
• Stage 3: Heat up to 60 degrees and dry for 5 hours. The color and shape have been fixed, just need to remove the remaining moisture.
• Stage 4: heat up to 65 degrees and dry for 3 hours. Thoroughly eliminate moisture to achieve the effect of drying.

  Note: generally not suitable for the early temperature is too high, you can use low temperature, a little longer time, the internal moisture of soybeans will be discharged, after all, just out of the high moisture content of soybeans, directly on the high-temperature speed, but easy to cause the shape color change, not too beautiful. 

The principle of beans dryer machine working:

  Baixin air energy heat pump dryer uses the reverse Carnot principle. The refrigerant is compressed by the compressor to become high-temperature and high-pressure gas, enters into the heat exchanger through the pipeline, and then passes through the fan to remove the heat generated by the heat exchanger send it to the drying room to heat and dry the seafood products and other materials, so that the seafood products are dried, and the moisture is discharged from the moisture outlet. The dehumidification system has a heat recovery device, and the recovered heat is used to heat the fresh air, which can save 60%-70% of the fresh air preheating energy consumption.
