Microwave thawing is the use of molecular vibration to produce elastic collision with the surrounding molecules, friction heat, and its heating method is generated from the product materials. This method has the advantages of low production cost, high efficiency, no bacterial growth and small floor area, which is unmatched by other methods.

The main characteristics of microwave thawing are as follows

Because microwave can directly heat the material in-depth, no conduction process is needed. It takes only 2 minutes for a piece of meat in 25 kg to rise from - 15 ℃ to - 4 ℃. The thawing time is changed from "hour" to "minute".

Saving investment, environmental protection and no pollution

A large number of shelves and floor space required for natural thawing are saved, and thawing can be carried out in the package, so as to reduce the requirements on the sanitary environment and avoid the waste of water resources in the process of hydrolysis freezing. For example, in a beef jerky processing plant, there are 8 self provided wells, which can continuously pump water from the ground for 24 hours before they can be used in the upper thawing workshop. This is a great waste of water resources. The oily sewage formed after thawing increases the burden of sewage treatment, and causes the loss of oily substances.

Ensure the nutrition of materials, no corruption.

Because the process of microwave thawing is cold storage, it can avoid the bacteria proliferation and liquid exudation in the process of processing, and reduce the meat loss rate. In the process of microwave thawing, because the wavelength of 915MHz is longer than 2450MHz, it has stronger penetration ability, and is more suitable for processing large food materials. This frequency is more suitable for thawing process.

Microwave thawing and temperature regulating equipment has been widely used in foreign food enterprises, and the fast-growing food enterprises in China are gradually using it. With the rapid development of China's economy and the increasing improvement of people's living standards, food quality requirements as the guarantee of food safety has become the focus of people's attention. At the same time, the environment and resource requirements do not allow the existence of extensive processing methods, so the traditional thawing method is far from meeting the development requirements of modern food processing enterprises. In order to meet the needs of China's food processing enterprises, through continuous research and exploration, we have developed a domestic leading microwave thawing and rewarming equipment. The microwave working frequency is 915MHz, and the power output is above 20kw-200kw, which can fully meet the requirements of product quality and output of different manufacturers. Compared with foreign microwave equipment, it has the advantages of less investment and convenient operation and maintenance; Compared with the traditional thawing method, it has the advantages of low investment, high efficiency, low operation cost, high product quality, convenient control and operation. Microwave thawing is the first choice for food processing enterprises, and it is also the development direction of food thawing technology in China.
