Description

Technical Field

[0001] The utility model relates to the technical field of freeze dryers, in particular to an ultra-low temperature automatic defrost vertical freeze dryer. Background Technique

[0002] The ultra-low temperature automatic defrost vertical freeze dryer freezes the moisture in substances through freezing technology, and then sublimates the frozen moisture under vacuum conditions, thereby realizing the drying of substances. This equipment has an automatic defrost function and can automatically defrost at low temperatures to ensure the normal operation of the equipment. The internal temperature of the ultra-low temperature dryer will remain at a relatively low level during the drying process, usually below zero degrees. Therefore, the dried items will also be in a low-temperature state. Therefore, when taking out the dried items, heat-insulating gloves or fixtures need to be worn to avoid direct hand contact, thereby reducing the risk of frostbite.

[0003] When taking out the dried items, there is a certain risk. Opening the cabinet door allows the dried items to adapt for a period of time before taking them out, gradually raising the temperature and reducing the impact of the temperature difference on the human body. At this time, the dried items are located in the drying chamber and the temperature rises slowly, wasting a lot of time. Therefore, an ultra-low temperature automatic defrost vertical freeze dryer is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an ultra-low temperature automatic defrost vertical freeze dryer to solve the problem raised in the above background technique, that is, when taking out the dried items, there is a certain risk. Opening the cabinet door allows the dried items to adapt for a period of time before taking them out, gradually raising the temperature and reducing the impact of the temperature difference on the human body. At this time, the dried items are located in the drying chamber and the temperature rises slowly, wasting a lot of time.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is an ultra-low temperature automatic defrost vertical freeze dryer, including:

[0007] A freeze dryer, which includes a cabinet body, a drying chamber and a shelf;

[0008] The drying chamber is opened in the middle of the cabinet body, and the shelves are fixed in the drying chamber and are evenly distributed;

[0009] A limiting component, which includes an electric push rod, a fixing plate, a rotating shaft, a torsion spring, an L-shaped limiting plate, a square through hole, a T-shaped movable block and a spring;

[0010] The electric push rod is embedded inside the cabinet body and is located at the rear end of the drying bin. The fixing plate is fixed on the inner side edge of the drying bin, the rotating shaft is fixed on the side edge of the fixing plate, the torsion spring is sleeved on the rotating shaft, the L-shaped limiting plate is sleeved on the rotating shaft, a square through hole is opened at one end of the fixing plate, the T-shaped movable block is inserted into the square through hole, and the spring is sleeved on the T-shaped movable block.

[0011] Further, one end of the torsion spring is fixed on the L-shaped limiting plate, and the other end is fixed on the side edge of the fixing plate. One end of the spring is fixed on the side edge of the fixing plate, and the other end is fixed on the T-shaped movable block.

[0012] Further, a set of limiting components are correspondingly arranged above each layer board, and the L-shaped limiting plate is located at the front end of the drying bin.

[0013] Further, the T-shaped movable block is movably connected in the square through hole and is also movably connected to the side of the L-shaped limiting plate.

[0014] Further, the freeze dryer further includes a cabinet door and a sleeve;

[0015] The cabinet door is movably connected to the drying bin opening, and the sleeve is fixed on the side of the cabinet door.

The electric push rod extends, and the box for placing the dried items is pushed out. When it is pushed to the L-shaped limiting plate and stops, at this time, most of the box is located outside the cabinet body and is in contact with the outdoor environment. After the temperature rises, the T-shaped movable block in the square through hole is pulled, driving the spring to extend. The other end of the T-shaped movable block disengages from the L-shaped limiting plate, and under the action of the torsion spring, the L-shaped limiting plate rotates around the rotating shaft and lifts up. At this time, the box can be taken down. This setting can accelerate the temperature rise speed and improve the drying efficiency.
