Bird's nest freeze-drying equipment and freeze-drying process thereof

Abstract

The invention relates to the technical field of freeze-drying, and discloses bird's nest freeze-drying equipment and a freeze-drying process thereof.The bird's nest freeze-drying equipment comprises a freeze-drying box, a freeze-drying cavity with an opening in one side is formed in the freeze-drying box, and a plurality of partition plates are arranged in the freeze-drying cavity at intervals; mounting plates with the number equal to that of the partition plates are fixed to the cavity walls of the two opposite sides of the freeze-drying cavity respectively, the partition plates are arranged between every two adjacent mounting plates at the same horizontal height in a sliding mode, and limiting pieces used for preventing the partition plates from moving out of the freeze-drying cavity are connected to the freeze-drying box; each mounting plate is slidably provided with a length-adjustable shifting rod, the shifting rods are located on the upper sides of the partition plates close to the shifting rods, and the mounting plates are provided with first driving parts used for driving the shifting rods to move horizontally and second driving parts used for driving the shifting rods to move vertically. The edible bird's nest cooling device has the effects of high edible bird's nest cooling uniformity and good finished product quality.

Description

technical field [0001] The present application relates to the technical field of freeze-drying, in particular to a bird's nest freeze-drying equipment and a freeze-drying process thereof. Background technique [0002] Freeze-drying is a drying technology using the principle of sublimation, which can quickly freeze the dried material at a low temperature, and then directly sublimate the frozen water molecules into water vapor in a suitable vacuum environment. It is widely used in food and in the field of pharmaceutical processing. [0003] When bird's nest is produced, its production process usually includes a process of drying with freeze-drying equipment. Traditional freeze-drying equipment includes a freeze-drying box, and the interior of the freeze-drying box is provided with multiple partitions. During freeze-drying, bird's nests are laid on the partitions to be frozen in contact with cold air to form a freeze-dried product. [0004] However, when the above-mentioned f...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned freeze-drying equipment freeze-dries the bird's nest, only the surface of the bird's nest exposed to the partition will contact the cold air in the freeze-drying box, while the surface of the bird's nest attached to the partition is difficult to contact the cold air, and there is a risk of being exposed to cold air. The problem of unevenness affects the quality of finished products and needs to be improved
