Onion Dehydrator Machine

Onion is a multifunctional health food. It is native to central and West Asia. There are many different varieties of onions, which are used in food all over the world. It is rich in a variety of nutrients and is very popular. Dehydrate onions into onion powder can effectively improve the shelf life of onions and facilitate transportation. 
Therefore, onion dehydrator machine is extremely important. So what are the current onion dehydrator machine? How to choose a suitable onion dehydrator machine? Next, let's learn about the onion dehydrate process and how to choose the right onion dehydrate machine.

This traditional method of dehydrate onion is economical and does not require any investment. However, because the dehydrate effect is greatly affected by the environment and is not easy to control, the dehydrate color of onion is uneven, and even defective onion may appear. During the dehydrate process of onion, a certain amount of manual turnover is required. What’s more, if you have a large amount of onions, and the traditional dehydrate process is time-consuming and labor-consuming, then you need a professional onion dehydrate equipment.
And most onion product manufacturers use onion dehydrator machine.

This dehydrate method is to use onion dehydrator machine to carry out reasonable dehydrator of onion. It can not only solve the shortcomings of the traditional method of dehydrate onion, but also improve the yield and increase the efficiency of dehydrate onion. At present, onion dehydrate room, mesh belt onion dehydrator machine and all-in-one onion dehydrator machine are widely used. Let me introduce to you the usage and dehydrate principle of the three machine.

Heat pump dehydrator machine

Step 1. wash the onion and select the ones with poor quality during the washing process.
Step 2. then cut the onions and place them evenly on the tray. Do not stack them too much to affect the dehydrate effect.
Step 3. push the cart into the dehydrate room to dry for 8 hours.
If we use the onion dehydrate oven, the equipment is equipped with a small cart with a tray and a tray rack. The heat source of the onion dehydrate 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 dehydrate and processing of onion.

Components of onion dehydrator room machine

One set onion dehydrator machine contains: heat pump dehydration host, dehydration chamber, fan frame with fan, trolley with tray. The dehydration chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays.

Advantages of onion dehydrator room machine

The drying machine can be equipped according to the user's requirement and the production demands.

Mesh belt dehydrator machine

Step 1. wash the onion and select the ones with poor quality during the washing process.
Step 2. then cut the onions and place them evenly on the tray. Do not stack them too much to affect the dehydrate effect.
Step 3. put the onion slices at the feeding port, and the onion slices will enter the dehydrator with the feeding conveyor for dehydrate.
If we are using a mesh belt type onion dehydrator, 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 dehydrate structure. The onions are dried and dehydrated layer by layer from top to bottom. The dehydrate speed is fast and the production efficiency is high. It is very suitable for the dehydrate and processing of large quantities of onions.

Components of mash belt onion dehydrator machinery

One set mesh belt onion drying machine contains: homogenizer, feeding conveyor,dryer host, output conveyor, observation door, heat source, air intake system, control panel. The onion dryer machine consists of 4 parts, namely the feed conveyor, the main machine of the mesh belt onion dryer machine, the heat source and the discharge conveyor. The reformer provides heat, and the through-flow mesh belt onion dryer machine is the main body of the drying equipment, which consists of a cabinet and multi-layer conveyor belts; the electrical control system controls the start, operation and stop of the entire equipment. With the cooperation of other auxiliary components, the drying equipment completes the drying and discharging process of onion, and realizes the drying process of onion drying. 

The working principle of continuous mesh belt onion dryer machine

Mesh belt onion dryer machine is a continuous production drying equipment. The main heating methods are electric heating, steam heating and hot air heating. Its main working principle is to distribute the onion evenly in the network. Through the operation of the machine, the onion moves in the dehydrator, and the hot air extracts the water vapor of the onion. So as to achieve the purpose of drying. The working temperature is 40-120 degrees Celsius. The drying cycle is 1-5 hours. Mainly used for agricultural and sideline products such as fruits and onions, Chinese herbal medicines, etc. The equipment is easy to operate, saves time, has a healthy drying process, and protects the environment.

3. All-in-one dehydrator machine

Its drying principle is the same as that of the onion dehydrator amchine room. If we use the onion all-in-one dehydrator machine, the machine is equipped with a trolley with tray and tray rack. When drying onion, we put it in a tray, put it on the tray rack of the cart, and then push it into the onion drying room for drying. The heat source of onion 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 onion. 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 onion all-in-one dehydrator 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 onion dehydrator machine

First of all, it depends on our demand for onion processing. For large output, use a onion mesh belt dehydrator machine. Generally, the output of a onion mesh belt dehydrator machine is 300-2000kg/h. For small output, the output of a heat pump dehydrator is 100-5000kg/batch. Oven length and mesh belt layers can be customized. We can choose and match them reasonably according to our own processing requirements.

Onion dehydrator process is becoming more and more popular in the world, and onion dehydrator machine also has bright prospects. Do you want to start a onion business? If you want to know more professional questions about onion dehydrator machine, please feel free to contact us online!
