What are Dehydrated Vegetables?

‌‌Dehydrated vegetables are fresh vegetables that have been washed, dried, and processed to remove most of the water in the vegetables. ‌This type of dried vegetables is easy to store and transport, and can effectively regulate the peak and off-peak seasons of vegetable production. When eating, just soak it in clean water to restore it, and retain the original color, nutrition and flavor of the vegetables. ‌

The production process of dehydrated vegetables includes the following steps:

‌Raw material selection‌: Select vegetable varieties with high moisture and strong fleshy texture, such as green vegetables, cowpeas, radishes, etc.
‌Washing and drying‌: Wash the selected vegetables and dry them to remove most of the water.
‌Cutting and blanching‌: After cutting the vegetables into shape, blanch them to make them easier to dry.
‌Cooling and draining‌: The blanched vegetables need to be cooled and drained to shorten the drying time.
‌Drying‌: Place the cooled vegetables in a drying room and dry them at a temperature of about 65 degrees Celsius for about 5 hours. The main varieties of dehydrated vegetables include carrots, edible fungi, cabbage, kale and ginger. There are two types of drying methods: natural sun drying and artificial dehydration. Artificial dehydration includes hot air drying, microwave drying, puffing drying, infrared and far infrared drying, vacuum drying and other methods. Among them, freeze-vacuum dehydration is an advanced vegetable dehydration method that can retain the original color, aroma, taste and shape of fresh vegetables, and has ideal rapid rehydration.

Dehydrated vegetables are not only more convenient and faster in storage and transportation, but also retain their nutritional value. Although dehydrated vegetables that are naturally dried or hot air dried will lose some water-soluble vitamins and bioactive ingredients, minerals, fiber, protein, starch and other ingredients can be retained. In particular, vegetables dehydrated by freeze-vacuum method have most of their nutrients retained, and the color and flavor are also better. Therefore, dehydrated vegetables can not only improve the nutritional content and flavor of products as ingredients, but also improve the food structure, becoming a convenient food choice in modern life.

Can I use a hot air circulation oven to dehydrate vegetables?

The hot air circulation oven is a kind of equipment specially designed for industrial mass production. It is widely used in the drying of raw materials, Chinese herbal medicine slices, extracts, powders, granules, granules, water pills, packaging bottles and other materials in the pharmaceutical industry. In addition, it is also suitable for drying dehydrated vegetables, feed, MSG seasoning, chemical pigments, rubber, fiber, electronic components, new materials, clothing, food and other industries. The hot air circulation oven adopts a high-temperature resistant circulation fan. The forced hot air heated by the electric heating tube or steam heat exchanger circulates in the box, which enhances the heat transfer, increases the water evaporation rate, and shortens the drying time. The whole box adopts a fully enclosed structure, and the hot air circulates in the box to reasonably discharge the hot and humid air and replenish fresh air. The oven is equipped with an automatic temperature control system, and an adjustable air distribution plate is installed in the temperature control box, and the temperature in the box is uniform. It adopts a low-noise energy-saving built-in circulation fan with balanced operation, which greatly reduces the noise and heat loss of the equipment. The air inlet is equipped with an air filter and a dehumidification device is standard.

In addition, the hot air circulation drying oven for vegetables can retain the original nutrients and colors of vegetables during the drying process. The temperature range of the drying oven is 40-70 degrees, the material is 304 stainless steel, electric heating, and the output is 50-260kg each time. It is suitable for hot air circulation drying of vegetables, fruits, preserved fruits, grains, beans, etc. to retain the original nutrition and color of vegetables.

In summary, the hot air circulation oven is an effective method for dehydrating vegetables. It can improve drying efficiency and shorten drying time while retaining the nutrients of vegetables.

What are the advantages of hot air circulation oven?

‌The advantages of hot air circulation oven mainly include efficient and uniform heat treatment, energy saving and environmental protection, easy operation and maintenance, high temperature capacity, uniform heating, efficient drying, energy saving and environmental protection, precision control, safety and reliability. ‌

‌Efficient and uniform heat treatment‌: The hot air circulation oven realizes uniform circulation of hot air through the built-in fan and air duct system, ensuring that the temperature in every corner of the oven can be kept consistent, thereby realizing efficient and uniform heat treatment of materials. Whether it is drying, curing or heat treatment, the hot air circulation oven can complete it in a short time, greatly improving production efficiency‌. ‌Energy saving and environmental protection‌: The hot air circulation oven fully considers energy saving and environmental protection factors when designing. The heating elements used are mostly high-quality quartz glass tubes or far-infrared directional radiators. These elements have the characteristics of high radiation coefficient and low energy consumption, which can significantly reduce energy consumption. At the same time, when the hot air circulation oven is running, it reduces the loss of heat energy and improves the utilization rate of heat energy through the hot air circulation method. In addition, some advanced hot air circulation ovens are also equipped with intelligent control systems, which can automatically adjust the temperature and wind speed according to actual needs to further achieve energy saving and environmental protection‌. ‌ ‌Easy to operate and maintain‌: The hot air circulation oven is designed and manufactured with full consideration of the user experience. Its operation is simple and easy to understand, and users only need to follow the instructions in the operating manual. At the same time, the internal structure of the oven is clear and users can easily perform maintenance and care. In addition, some advanced hot air circulation ovens are also equipped with intelligent control systems and fault diagnosis systems, which can automatically detect and troubleshoot faults, reducing maintenance costs‌.

‌High temperature capability‌: The high temperature hot air circulation oven can provide a high temperature environment, usually reaching a temperature of several hundred degrees Celsius or even higher, which is suitable for materials and processes that require high temperature treatment‌.

‌Uniform heating‌: The hot air circulation system can evenly distribute heat to each area inside the oven and the surface of the material, achieving uniform heating of the material and avoiding excessive temperature gradients‌.

‌Efficient drying‌: Through the circulating air system, hot air can quickly flow through the surface of the material, accelerating the evaporation of moisture and the drying process of the material, and improving the drying efficiency‌.

‌Precision control‌: Equipped with a high-precision temperature controller, it can monitor and adjust the temperature inside the oven in real time to achieve precise temperature control. The control system can accurately adjust the heating power and wind speed according to the set requirements to meet the needs of different materials and processes.

‌Safe and reliable‌: The oven is equipped with multiple safety facilities, such as over-temperature protection device, overload protection device and emergency stop button, etc., to ensure the safety of operators and equipment.
