How to Dry Beans in a Dehhydrator/How to dehydrate Beans 

Beans are diverse and nutritious and are cultivated all over the world. In recent years, beans have become more and more popular due to their high nutritional value and good taste. The deep processing of beans also has a huge market all over the world. Drying the beans not only prolongs the shelf life but also facilitates storage.

So how to drying the bean? Next, I will share two ways of drying bean. One is to use the traditional sun drying method, and the other is to use professional machine to dry beans.

The traditional sun dehydrating method

Step 1. Washing the fresh beans and remove the heads on both sides.
Step 2. Slicing the beans into evenly small pieces. If you want to dry whole green beans, you can skip this step.
Step 3. Putting the beans into the boiling water and continue to boil for 1 minute.
Step 4. Removing the beans from the boiling water and cool.
Step 5. Putting the cooled beans on the tray, and put the tray in the sun for 1-2 days.
This traditional method of drying bean is economical and does not require any investment. However, because the drying effect is greatly affected by the environment and is not easy to control and even defective bean may appear. What’s more, the traditional drying process is time-consuming and labor-consuming, and drying beans requires a huge space, if you want to dry beans in large quantities, it is recommended that you use a professional bean drying machine.

The professional machine dehydrating beans

Therefore, dehydrating beans with a dehydrator is not only a possibility, but also the best choice. A professional bean dehydrator is an indispensable part for bean processing or agricultural production. So,how to dry bean in a dehydrayor? Next, I will share with you the way to drying in a dehydrator.
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 litt longer time, the internal moisture ofsoybeans will be discharged, after all, just out of the high moisture content of soybeans, directly on the high-temperature speed, but easyto cause the shape color change, not too beautiful.
Next I will introduce you the types of bean dryers and how to choose the right one.

Bean dehydrator room

The bean dehydrator is equipped with a small cart with a tray and a tray rack. When we dry the bean, we lay bean in the tray, put it on the tray rack of the cart, and then push it into the bean drying room for drying. 
The heat source of the bean drying room is air. The heat in the air is absorbed by the heat pump compressor. After compression and release, a large amount of high-temperature hot air can be obtained, so as to realize the continuous and uniform drying and processing of bean.

Advantages of bean dehydrator room

1 Wide application. Suitable for vegetable, fruit, seafood, spice etc different kinds of material.
2 High drying capacity. Each hour can drying 3-4kg water.
3 Better drying effect. Can better keep material shape , color , nutrition etc.
4 Simple operating. PLC touch screen control panel , can set up temperature, humidity in advance 
5 Low energy consumption. Heat pump system, can save 70% energy.

Mesh belt bean dryer machine

Next, I will introduce you to the bean mesh belt dryer machine. 
If we are using a mesh belt type bean dryer machine, then this equipment has a wide range of heat sources, such as coal heating, gas heating, steam heating, biomass pellet heating, or electric heating. It is a multi-layer continuous drying structure. When drying the bean, we only need to put the bean slices at the feed inlet, and the bean slices will enter the dryer along with the feeding conveyor for drying.
The beans are dried and dehydrated layer by layer from top to bottom. The drying speed is fast and the production efficiency is high. It is very suitable for the drying and processing of large quantities of beans.

3. All-in-one dryer machine

Its drying principle is the same as that of the bean dryer room. If we use the bean all-in-one dryer machine, the machine is equipped with a trolley with tray and tray rack. When drying bean, we put it in a tray, put it on the tray rack of the cart, and then push it into the bean drying room for drying.
    
The heat source of bean all-in-one dryer is air. The heat in the air is absorbed by the heat pump compressor. After compression and release, a large amount of high-temperature hot air can be obtained, so as to realize the continuous and uniform drying and processing of bean.
The operation of this all-in-one drying equipment is relatively simple, and drying can be carried out only by plugging in the power supply. 

Advantages of bean all-in-one dryer machine

1. Stainless steel 304 material. The whole machine uses stainless steel material, can work a long time, and keep better heat preservation, bottom have wheeler, can move easily.
2. Great energy saving. Heat pump system design, low energy consumption, can save 75% energy than traditional electricity element heating.
3. Wide application easy operation. Fit for wide application, seafood, fruit, vegetable, spice, herbs, etc all can use it to dry.
4. Gentle drying. Temperature range 40-80°C, low temperature dehydrate processing can better keep material nutrition, during drying, no need to move the machine.

How to choose a suitable bean dryer machine

Having learned about the above three kinds of beans dryers, let me introduce you how to choose a bean dryer suitable for you.
First of all, it depends on our demand for bean processing. For large output, use a bean mesh belt dryer. Generally, the output of a bean mesh belt dryer is 300-2000kg/h. For small output, the output of a heat pump dring room is 100-5000kg/batch. The output of all-in-one bean dryer is the smallest, only 100-1500kg per batch. It is suitable for agricultural plants or small processing plants. Oven length and mesh belt layers can be customized. We can choose and match them reasonably according to our own processing requirements.

These are the three kinds of drying equipment explained by Baixin drying machinery company for you. Do you want to start a bean business? If you want to know more professional questions about bean dryer, please feel free to contact us online!
