New Development Of Food Freeze Dryer

New Development of Food Freeze Dryer

With the continuous development of food freeze dryer technology, there are traditional processes and bottlenecks in the development of various food industries. Under the huge market demand, various enterprises have also introduced freeze-drying technology and developed new products in combination with their own characteristic products. Breaking with tradition, freeze-drying technology can be applied in the food industry of yogurt, candied haws, and roast duck. The freeze-dried yogurt developed using fermentation technology and ultra-low temperature freeze-drying technology realizes the shelf life of yogurt at room temperature for one year, and such innovations break traditional food production methods Products are constantly emerging, and freeze-drying technology is combined with more and more subdivided food products. The new development of food freeze dryer is full of opportunities and challenges.

Food freeze-drying machine application In addition to the more common freeze-dried fruits in daily life, Beijing's traditional special food candied gourd, and roast duck are also added to the freeze-dried food field. "In order to solve the phenomenon that roast duck is packaged and then opened to become braised duck, the traditional roasting process and vacuum freeze-drying technology were combined in the product development, and the hanging furnace process was used in the front-end roasting process. The roast duck is made into slices in the way of simulating slicing and then vacuum freeze-drying. Using this technology can keep the quality of roast duck fresh, fragrant, crisp, and tender. In addition, adding some antioxidants can prevent the product from oxidation during the shelf life Deterioration." Dong Lijun, deputy general manager of Beijing Yushiyuan Food Co., Ltd., said when introducing his roast duck series products at the 19th Convenience Food Conference "New Opportunities for Freeze-Dried Convenience Snacks". 

At the same time, he mentioned that the roast duck lotus leaf cake, roast duck instant soup, and roast duck sauce products, which were completed with the above-mentioned technologies as the core, were combined into one package to realize the research and development of Beijing roast duck products with all elements.

In addition, food freeze-drying technology is also applied to candied haws. As a traditional specialty food in Beijing, the candied gourd has always been consumed as soon as it is full. After the hawthorn is mature, vacuum freeze-drying is carried out, and the freeze-dried hawthorn is dipped in sugar, and finally packed with nitrogen. Because freeze-dried hawthorn blocks or delays the migration time of fillings and moisture, the shelf life of the product can be extended from one day to three months, and the product can also be sold all over the country.
