15 H drying 1.7 Ton OniOn- buy vegetable dehydration machine

Onion is a kind of multifunctional health food. Drying can effectively extend the shelf life of long onions. Drying onions and natural drying in the sun will cause the skin of onions to be heated and easily necrotic, and the temperature is not controlled. It is dry in the shade, but it can also be too yin, and the yin is also easy to break.

For large quantities, it is recommended to use air-energy onion drying equipment. Use medium and low temperature hot air to dry, and the moisture will be discharged in time. After drying, the onions will not change color and have good rehydration. The key is that the air-energy onion drying equipment is very energy-saving. Electric use.

Useful Onion drying process

1. Rinse the onions, and pick out bad quality onions during the process of rinsing
2. Cut the onions and place them on the tray evenly. Do not stack them too much, which will affect the drying effect.
3. Drying
(1) Temperature: Vegetables generally have a relatively high water content, so it is necessary to set the non-low temperature hot air constant temperature drying. High temperature will destroy the nutritional value of vegetables. The drying temperature of onions should not exceed 50 ℃, and the accident rate during drying should reach more than 20%. Drying can be carried out in multiple stages. At first, the temperature is set to 50~40℃, then 40~30℃, and then down to about 35℃.
(2) Drying time: The drying cycle of a batch of onions is about 15 hours, and rapid drying will destroy the drying quality.
(3) Humidity: There is a certain amount of sugar in the moisture of vegetables, which makes dehydration difficult. It is very important to control the dehydration speed.

The composition of the onion dryer

1. Host: Air-energy heat pump drying dehumidifier (heat pump dryer uses little input electric energy to absorb free heat in the air to dry materials)
2. Drying room: Polyurethane foam insulation warehouse (customized), which is used to store materials and keep warm to prevent heat loss.
3. Drying room circulation system: The hot air circulation system brings heat to every corner of the drying room to increase the temperature of the drying room, and take away the water evaporated from the material.
4. Dehumidification and drainage system: Most of the high temperature and humid air in the roasting barn is condensed into water and discharged, and the excess water vapor is discharged through the fan.
5. Fully automatic intelligent control system: according to the appropriate drying process curve, automatically adjust the temperature, humidity, and drying time.
6. Unique energy-saving technology: high-efficiency tertiary waste heat recovery and dehumidification device, 30% more energy efficiency than ordinary heat pump dryers.


How are onions dehydrated? Dried onion processing method


The working principle of onion dryer machine

The heat pump dryer is a new type of high-efficiency energy-saving dryer. Its working principle is based on the principle of reverse Carnot cycle, using a small amount of electric energy and using a compressor to evaporate the common substance into a gaseous state in the evaporator after passing through the expansion valve. It also absorbs a large amount of heat energy in the air, and the gaseous working medium is compressed by the compressor into a high-temperature, high-pressure gas, and then enters the condenser to release heat, and heats the drying medium. Such continuous heating can heat the drying medium to 40°C-- 85°C.
