Onion dehydrator 

Onions play an important role in our daily diet. Eating onions regularly can enhance our immunity and resist aging. However, fresh onions have a short shelf life, and in rainy weather, the onions may rot. Therefore, onion dehydrator is not only good for preservation, but also provides more options for cooking methods. Some dried onions have entered the market and are deeply loved by people. So what are onion dehydrator machines? How to choose a suitable onion dehydrator machine? Now, Baixin Dehydration Company will share with you several onion dehydrator machines that are energy-saving, environmentally friendly, convenient, and have very good drying color and luster quality.


How to choose a suitable onion dehydrator?
Onion dehydrator are divided into three types: mesh belt onion dehydrator, onion dehydrator room and all-in-one onion dehydrator machine. In terms of output, the continuous mesh belt onion dehydrator machine is suitable for manufacturers with large output. Its output is 300-2000kg/h. The output of the onion dehydrator room machine is smaller than that of the mesh belt onion dehydrator machine, and the output is 100-5000/batch. The output of the all-in-one onion dehydrator machine is the smallest, and its output is 100-1500/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.

1. continuous mesh belt onion dehydrator 

Frist of all, let's take a look at the continuous mesh belt onion dehydrator machine with the largest output. Mesh belt onion dehydrator machine have 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 onions, just put the onions in the feeding port, and the onions will enter the dehydration with the feeding conveyor for drying. Onions are dried and dehydrate layer by layer from top to bottom. The drying speed is fast and the production efficiency is high, which is very suitable for the drying and processing of large quantities of onions.

The working principle of continuous mesh belt onion dehydrator machine

Baixin continuous mesh belt onion dehydrator 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 material evenly in the network. Through the operation of the machine, the onion moves in the dehydration, 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.

Components of continuous mesh belt onion dehydrator

One set continuous mesh belt onion dehydrator contains: homogenizer, feeding conveyor,dehydration host, output conveyor, observation door, heat source, air intake system, control panel. The onion dehydrator machine consists of 4 parts, namely the feed conveyor, the main machine of the mesh belt onion dehydrator machine, the heat source and the discharge conveyor. The reformer provides heat, and the through-flow mesh belt onion dehydrator 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 food, and realizes the drying process of food drying.

2. Onion dehydrator room machine

The second type of dehydration is the onion dehydrator room.
The onion dehydrator room machine is equipped with a trolley with trays and tray racks. When we dry the onions, we put the onions in the tray, on the tray rack of the cart, and push it into the onion drying chamber to dry. Onions are putted on the shelf car and enter the closed cycle drying room for drying without any pollution in the process. The heat source of the onion dehydrator room is air. The heat in the air is absorbed by the heat pump compressor. After being compressed and released, a large amount of high-temperature hot air can be obtained, so as to achieve uniform drying and processing of onions.

Components of onion dehydrator room

One set onion dehydrator room 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.

The working principle of onion dehydrator room

The onion heat pump dehydration uses the reverse Carnot principle to let the hot air circulating blower dry the vegatable. The fan impeller rotates, the outside air enters the oven, passes through the heater, forms hot air, and then enters the studio through the gap of the air distribution plate, and a large amount of hot air in the circulating flow continues to enter the new air inlet for supplementation. The moisture discharged after recovery is discharged from the exhaust port. The whole cycle makes the vegatable heated evenly and achieves the purpose of drying. Determine different temperature, time, color and moisture content during drying according to different varieties. It is better for the onion dehydrator to use the air energy heat pump drying system, and the heating of the air energy is a slow increase, can maintain the original tissue fibers and nutrients of the onions, and through the compressed air. The whole process of extracting air heat energy does not contain harmful substances, and it is also more energy-saving and environmentally friendly.  

Advantages of onion dehydrator room

1 Wide application. Suitable for onion, 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.

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

3. All-in-one onion dehydrator

The last onion dehydrator is the all-in-one onion dehydrator with the smallest yield.
The drying principle is the same as that of the onion dehydrator room. The all-in-one onion dehydrator is equipped with a cart with trays and tray racks. When drying onions, we put them in trays, put them on the tray racks of the cart, and then push them into the onion drying chamber for drying.
The heat source of the onion integrated dehydration is air energy. 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 achieve continuous and uniform drying and processing of onions. The operation of this all-in-one drying unit is relatively simple, simply plug in and dry.

Components of all-in-one onion dehydrator

One set all-in-one onion dehydrator contains: power jack, water outlet,exhaust air outlet, supporting wheels, PLC controller pancl, door lock, observation window,circulating air inlet, outlet for hot and dry air, PP tray, stainless steel tray, supporting racks for trys. The onion all-in-one has compact structure, good energy-saving effect, wide application range, high drying quality, convenient operation, simple installation and disassembly. It is the best drying equipment for small businesses, drying experiments and scientific research. The user only needs to connect the power to use, it is the easiest to operate onion dehydrator.

Advantages of all-in-one onion dehydrator

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.
