Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processing technology, specifically to a cantilevered door opening device for freeze-drying equipment. Background Technology
[0002] In the operation of freeze-drying equipment, opening and closing the equipment door is an important procedure. Traditional freeze-drying equipment door opening methods mostly rely on manual operation, which is not only labor-intensive and inefficient, but also prone to causing harm to operators in the low-temperature environment. Repeated opening and closing in low-temperature environments makes it difficult to ensure the smoothness and accuracy of each opening and closing action, which can easily lead to damage to the equipment door due to improper operation, affecting the normal use and lifespan of the equipment. At the same time, the traditional door opening method has a limited range of motion. For some large freeze-drying equipment, it is difficult for operators to conveniently operate the equipment door in different positions, which limits the flexibility and convenience of the equipment.
