Special features of microwave dryers compared to other drying equipment applications

1. The microwave dryer is dry and puffed, and the product rehydration is good:

Since the moisture in the material is rapidly vaporized by the microwave heating, a fine microporous structure is formed and maintained in the material, and good rehydration performance is obtained. It is especially suitable for corn, fruit and vegetable crispy puffing, fish belly puffing, pig skin puffing, multi-grain baking puffing, and the drying of oil-free instant noodles and easy-to-dissolve sugar added to coffee and milk tea. A certain aquaculture processing enterprise applied a number of Vijay microwave fish belly puffing equipment before and after, completely replacing the traditional fried salt puffing equipment, which not only improved the production environment, but also greatly improved production efficiency and reduced labor. A food factory in Fujian has built a production line of expanded corn flakes with a daily output of 2t, and Hangzhou and other places for the oil-free instant noodle microwave drying production line. The daily production of oil-free instant noodle cake can reach 300,000 to 400,000 bags, and the equipment can improve efficiency. Fuel-saving, but also guarantee the quality of the product.

2. Microwave drying equipment is suitable for drying of poor thermal conductivity or high viscosity materials:

Microwave can produce good processing results for foods, agricultural and sideline products that are less thermally conductive, viscous, and materials that require a large amount of original color and aroma. For example, if a tea company uses the microwave tea drying and killing equipment produced by Microwave Equipment Co., Ltd. and processes it into refined tea, the time required is shortened to 1/5 of the conventional method, and the moisture content of the tea is reduced to 3%, which maintains the tea original well. Some color and fragrance. Henan Pharmaceutical Co., Ltd. uses Weiyasi microwave vacuum drying equipment to reduce the moisture content of concentrated Chinese medicine extract from 40% to 5%, and the drying temperature should not exceed 65 °C. The color, aroma and pharmaceutical ingredients cannot be changed after the product is made. The equipment has a microwave output power of 20kW, an operating frequency of 2450MHz, a drying cycle of about 20min, a drying capacity of 20Kg/H, and a device size of 1680*1480*1700mm.

3, microwave drying equipment can be used to maintain the drying of the original color materials:

Konjac is a famous health food, which has low calorific value and has the effects of removing phlegm and dissipating swelling. It is exported to Western Europe and Japan. One of the important signs of the quality of its products is whether its color can be kept clean after being processed into konjac flour. In recent years, a food factory in Fujian has used microwave equipment to dry konjac to make powder, which has better preserved the original color and is favored by foreign businessmen. Similarly, the ginger can be used to dry the ginger and other materials, and the old process of sulphur-bleaching of ginger is discarded.

4. Microwave dryer is used for drying materials that need to be processed in a closed environment:

Some aquatic products such as grilled fillets, seaweed or shrimps that need to be cleaned in a closed environment without impurities and sediment can be dried by microwave. For example, Guangzhou Diwei Industrial Microwave Equipment Co., Ltd. Microwave Equipment Co., Ltd. has built a shrimp drying food microwave drying production line for a fishery comprehensive processing plant in Guangdong. The fresh shrimps are directly dried and sterilized by microwave after fishing and cleaning. The products are rich in flavor and flavor. Impurities and bacteria have reached export requirements. The product is changed from bulk to 25g pouch, and the product value is more than 4 times. For example, after washing, the down material is dried by microwave. Its color, feel and bulkiness are obviously better than steam drying method, and the integrity rate is high. After a microwave drying down in a factory in Jiangxi, the loss of fleece and flying silk is reduced by 3%. The fluffiness rate is increased by 14%-20% compared with the steam drying method. Another example is microwave oven-baked shrimp equipment used in a certain aquatic product in Wenzhou to dry, bake and sterilize shrimp. The food processed through microwave equipment is hygienic and safe, and fully meets the food QS certification standard.

The above is the special feature of microwave dryers compared to other drying equipment applications. Welcome customers, sample test, discuss cooperation!
