Embodiment

[0042] Embodiment: a kind of lyophilizer of vacuum deicing and defrosting, as figure 1 and figure 2 As shown, a freeze-drying chamber 1 is included, and a partition plate 11 is fixed in the middle of the freeze-drying chamber 1. The partition plate 11 divides the interior of the freeze-drying chamber 1 into a freeze-drying chamber 12 and a defrosting chamber 13. A vacuum pump 121 is fixedly connected to the position of the freeze-drying chamber 1 corresponding to the freeze-drying chamber 12 , and the vacuum pump 121 communicates with the freeze-drying chamber 12 . The partition plate 11 is fixed with an opening and closing valve 111 , and gas can enter the defrosting chamber 13 from the freeze-drying chamber 12 through the opening and closing valve 111 . The vacuum pump 121 vacuumizes the inside of the freeze-drying chamber 12, and is used for the freeze-drying machine to vacuum freeze-dry fruits and vegetables. A large amount of steam is generated during the freeze-drying...

Abstract

The invention discloses a freeze dryer for vacuum deicing and defrosting, which belongs to the technical field of freeze dryers. The freeze-drying chamber and the defrosting chamber, the freeze-drying chamber is fixedly connected with a vacuum pump at the position corresponding to the freeze-drying chamber. The defrosting chamber; the position corresponding to the defrosting chamber of the freeze-drying chamber is fixedly connected with a steam pipe, the steam pipe is connected with the defrosting chamber, and the end of the steam pipe away from the freeze-drying chamber is fixedly connected with a steam generating device capable of transmitting hot steam into the steam pipe. The invention has the effect of rapidly melting the ice in the freeze dryer and effectively improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of freeze dryers, in particular to a freeze dryer for vacuum deicing and defrosting. Background technique [0002] At present, the freeze dryer originated from the vacuum freeze-drying technology in the 1920s. In the 21st century, vacuum freeze-drying technology has been widely used in fields other than medicine, biological products, food, blood products, and active substances. In the food industry, freeze-dried fruits and vegetables have the advantage of being able to retain the nutrition of fresh fruits and vegetables, and the demand is also increasing. At present, the freeze-dried fruits and vegetables freeze-drying machines use large-scale freeze-drying machines, which can freeze-dry a large amount of fruits and vegetables at one time. When the freeze dryer freezes these fruits and vegetables, a large amount of steam will be generated, and the steam will freeze in the freeze dryer. If the ice is not clea...
