The invention discloses a sealing ring for a freeze-drying box of a freeze dryer. The freeze dryer and electric fans are included, the freeze dryer comprises the freeze-drying box and a cold trap box,a box door is arranged on the side wall of the freeze-drying box, a second annular magnet is fixedly embedded in the bottom wall of an inner cavity of the freeze-drying box and in the outer side of athrough hole, the outer bottom wall of the freeze-drying box is fixedly connected with the cold trap box, switches are fixedly installed on the side wall of the freeze-drying box and above the box door, and the switches are electrically connected to the electric fans. The electric fans are installed on a connecting post, four electric fans are installed between each layer of freeze-dried plates,the four electric fans are evenly distributed, the wind generated by the electric fans is directed in four directions, when the box door is opened for articles to be placed, no matter which directionthe connecting post is rotated in, it is ensured that the wind generated by the electric fans can be blown to the box door to prevent dust from entering the inside of the freeze-drying box, and the sealing ring has dust proof and disinfection effects, and is simple and effective.
Description
technical field [0001] The invention relates to the technical field of freeze-dryer disinfection, in particular to a sealing ring used for a freeze-drying box of a freeze-dryer. Background technique [0002] The vacuum freeze-drying technology originated in the 1920s. After decades of ups and downs and lingering, great progress has been made in the last 20 years. In the 21st century, vacuum freeze-drying technology is unmatched by other drying methods. The advantages are more and more favored by people. In addition to being widely used in the fields of medicine, biological products, food, blood products, and active substances, its application scale and field are still expanding. [0003] But in the prior art, when placing articles in the freeze dryer, it is easy to bring in dust when opening the door of the freeze dryer, which will pollute the articles to be frozen, which is very inconvenient, so it is necessary to The freeze dryer develops a function of dust prevention and...
