Embodiment Construction

[0027] The specific embodiment of the present invention is described below:

[0028] As shown in accompanying drawing 1, the vacuum freeze-drying cabin 1 that implements according to the present invention comprises horizontal cylindrical cabin 11, the square cabin 12 that is positioned at described cylindrical cabin 11 below, two front and back ends that are positioned at described drying cabin. Independent cabin door 13 respectively. The diameter of the cylindrical chamber is 2200 mm, which is 200 mm smaller than that of the prior art with similar production capacity, thus greatly reducing the vacuum volume.

[0029] As shown in accompanying drawing 2 and accompanying drawing 3, in the inside of described cylindrical cabin 11, two groups of symmetrical heating plates 21 are arranged in parallel. The heating plate assembly 2 is removed. As shown in accompanying drawing 4, in the middle of heating plate 21, material frame 22 is arranged, and this material frame 22 is that can...

Abstract

The invention relates to a vacuum freezing drying chamber, which comprises a horizontal type cylinder chamber, a square chamber arranged below the cylinder chamber, two respectively independent cabin doors arranged at the front and rear end parts of the drying chamber and a pipeline arranged at the side part of the drying chamber. A feed-plate and a material shelf are arranged in the interior space of the cylinder chamber and a square trap and an ice melting can abutting on each other longitudinally or transversely are arranged in the interior space of the square chamber; an isolation door is arranged between the trap and the ice melting, and a movable door is arranged between the trap and the cylinder chamber. The integrated arrangement of internally arranging the trap and the ice melting for the invention greatly reduces the vacuum space of the drying chamber, shortens the gas-liquid channel for separating water and melting ice, saves more energy, and reduces the space for land occupation of the equipment and is convenient for implementing the modular installation and system upgrade.

Description

technical field [0001] The invention relates to a vacuum freeze-drying cabin. Background technique [0002] Vacuum freeze-drying (abbreviated as freeze-drying) technology was born in 1811 and was used for the dehydration of organisms at that time. By 1909, this method was used to preserve bacteria, viruses and serum, and achieved good results, which made the vacuum freeze-drying technology practically applied. In 1930, food freeze-drying experiments began. In 1935, the active heating method was used for the first time in the vacuum freeze-drying process, and the time required for sublimation drying was shortened, which made it possible to use freeze-drying for production. In the same year, Britain proposed the food vacuum freeze-drying technology. The most original vacuum freeze-drying equipment appeared in Denmark in 1943. In 1961, the British laboratory inspection factory began industrial production. [0003] Freeze-drying equipment can usually be divided into six maj...
