Problems solved by technology

However, the conventional condenser has only one coil structure, so once the refrigeration system fails, the coil will not be able to obtain enough cooling capacity to ensure the low temperature to capture the sublimated water vapor in the freeze-drying box, which will seriously affect the freeze-drying process of the drug

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing.

[0031] see figure 1 , figure 2 with image 3 , The horizontal condenser of the present invention includes a shell 1, a coil support 2, a first coil structure and a second coil structure.

[0032] The coil support 2 is fixed inside the casing 1 . The first coil structure and the second coil structure are jointly fixed on the coil support 2, and are used to provide cooling capacity to capture sublimated water vapor. The first coil structure and the second coil structure have different structures. One coil structure is a liquid nitrogen direct injection cooling structure, and the other coil is a flow-through silicone oil cooling structure. The two coils can serve as backups for each other. Among them, the first coil structure is a liquid nitrogen direct injection cooling coil structure, and the cooling capacity is directly provided for the coil by sublimation of liquid ni...

Abstract

The invention discloses a horizontal condenser, comprising: a shell; a coil support fixed in the shell; a first coil structure fixed on the coil support and providing cooling capacity; fixed on the The second coil structure on the coil support and provides cooling capacity. The present invention has two groups of coil tube structures that serve as backups for each other, so as to avoid the freeze-drying process of medicines being affected by the failure of the refrigeration system.

Description

technical field [0001] The invention relates to the field of pharmaceutical machinery, in particular to a condenser for a freeze dryer. Background technique [0002] Freeze dryers are mostly used in the pharmaceutical industry, where the condenser is mainly used to capture the sublimated water vapor in the freeze dryer box, and form a pressure differential driving force for the sublimated water vapor from the freeze drying box to the condenser to make it Ice forms on the surface of the condenser, allowing the freeze dryer to function properly. Therefore, the conventional freeze dryer will get enough cooling from the refrigeration system during operation to keep the coil at a low temperature to capture the sublimated water vapor in the freeze dryer cabinet. However, the conventional condenser has only one coil structure, so once the refrigeration system fails, the coil will not be able to obtain enough cooling capacity to ensure low temperature to capture the sublimated wate...
