Description

Technical Field

[0001] This utility model relates to the field of freeze dryers, specifically a freeze dryer with shock absorption function. Background Technology

[0002] After production, fabrics need to be dried and rolled up. Various drying methods exist, such as sun drying, boiling, oven drying, spray drying, and vacuum drying. However, common drying methods typically involve temperatures above 0°C or higher. Products obtained through this process generally suffer from volume reduction and hardening, with most volatile components lost, some heat-sensitive substances denatured or deactivated, and some even oxidized. Freeze dryers, on the other hand, utilize compressed air drying. Freeze drying works by lowering the temperature of the compressed air, causing moisture to evaporate. The working principle of a freeze dryer is similar to that of a refrigerator; compressed air passes through refrigerated compressed air pipes, where its temperature drops to the required level, achieving the desired dryness.

[0003] Vacuum freeze-drying technology has wide applications in bioengineering, pharmaceutical industry, food industry, materials science, and deep processing of agricultural and sideline products. Because the cooling dryer requires the coordinated operation of multiple units, vibrations are generated during its operation. Excessive or prolonged vibrations can cause some parts to loosen, leading to dimensional deviations at the connections between units and ultimately rendering the unit inoperable.
