Method for microwave vacuum drying of edible bird's nests

Abstract

The invention discloses a method for microwave vacuum drying of edible bird's nests. The method comprises the following steps of immersing raw edible bird's nests by RO water for 20-30min, manually and gently picking hair out of the edible bird's nests, carrying out secondary immersion of the edible bird's nests by clear water for 20-30min to obtain edible bird's nest cups, carrying out draining and setting of the edible bird's nest cups, drying them in a vacuum microwave dryer having a vacuum degree of 0.060Mpa and microwave power of 230KW for 30min, taking out the dried edible bird's nest cups in a cleaned work room, and carrying out grading, weighing and packaging. The method can effectively improve production efficiency, guarantee stable product quality, greatly improve a drying rate, solve the traditional drying method problem of unstable product quality and effectively improve production efficiency.

If the drying temperature is too high, it is easy to cause the product to change color

[0007] 3. Combination of heat lamp and fan blowing and drying method, the drying temperature is low, but affected by environmental factors such as space humidity and temperature, the drying time is as long as 8 to 12 hours, which is difficult to control the water content in the finished product and prone to microorganisms Infection, there are problems such as low production efficiency and unstable product quality
