Abstract

The invention relates to a paper document vacuum drying machine which comprises a machine frame and a vacuum tank installed at the upper portion of the machine frame. A horizontally-arranged plate-type heat exchanger, a temperature sensor and a pressure sensor are arranged in the vacuum tank, the lower portion of the machine frame is provided with a freezing-drying filter, the freezing-drying filter is respectively connected with the vacuum tank and a vacuum pump through air pipeline and respectively connected with the plate-type heat exchanger and a refrigerator assembly through Freon pipelines, and the temperature sensor, the pressure sensor, the vacuum pump and the refrigerator assembly are respectively connected with a controller installed on the machine frame. The paper document vacuum drying machine is simple in structure, convenient to operate, capable of quickly drying paper documents, good in drying effect, shirt in drying time and capable of effectively preventing harmful microorganisms, pests and water from damaging the paper documents, does not produce secondary damage to the documents and can meet the drying requirement of a large amount of mildewed, sticky and drowned documents.

Description

Technical field: [0001] The invention relates to a vacuum dryer for paper documents. Background technique: [0002] At present, paper documents that have been soaked in water for a long time will breed file pests and molds, causing serious damage to the documents such as adhesion and hydrolysis. At present, there is no special equipment for drying these documents, and the method adopted is mainly hot air. Drying or ordinary drying, drying, long drying time, and the dried documents are easy to stick, and the drying effect is poor. Using the existing methods to dry these moldy, sticky and other flooded documents will cause secondary damage. Even cause permanent damage, making important files unrecoverable. Invention content: [0003] In order to make up for the deficiencies in the prior art, the present invention provides a vacuum dryer for paper documents, which is simple in structure, easy to operate, can quickly dry paper documents, has good drying effect, short drying t...
