Onion Drying Plant

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, drying onions 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 drying plants? How to choose a suitable onion drying plant? Now, Baixin Drying Company will share with you several onion drying plants that are energy-saving, environmentally friendly, convenient, and have very good drying color and luster quality.

How to choose a suitable onion drying plant?

Onion drying plant are divided into three types: mesh belt onion drying plant, onion drying room and all-in-one onion drying plant.
In terms of output, the continuous mesh belt onion drying plant is suitable for manufacturers with large output. Its output is 300-2000kg/h. The output of the onion drying room plant is smaller than that of the mesh belt onion drying plant, and the output is 100-5000/batch. The output of the all-in-one onion drying plant 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. All-in-one onion drying plant

The first onion drying plant is the all-in-one onion drying plant with the smallest yield.
The drying principle is the same as that of the onion drying room plant. The all-in-one onion drying plant 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 drying 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 drying plant

One set all-in-one onion drying plant 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 plant 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 drying plant.

Advantages of onion dehydartion room machine

1. Stainless steel 304 material. The whole plant 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, onion, 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 plant.

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

2. Onion drying room plant

The second type of drying plant is the onion dryer room.
The onion drying room plant 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 drying 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 drying room plant

One set onion drying room plant contains: heat pump drying host, drying chamber, fan frame with fan, trolley with tray. The drying chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays. Put the onions into the material tray, insert the material tray into the material cart and push it into the drying room, and close the sealing door to start drying production. The drying temperature range is 65 ℃ - 85 ℃, and the drying temperature is divided into different temperatures, and the temperature is gradually lowered. Generally, the drying time is about 8-10 hours to complete a batch.

The working principle of onion drying room plant

The onion heat pump drying plant uses the reverse Carnot principle to let the hot air circulating blower dry the vegatable. Heat Pump Drying Compressor Heat Exchanger Blocked Radiator (External to Plant). Compressor and other equipment make up the refrigerant circulation system. 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.
