Dehydrating apparatus for alcoholic group bactericidal and fresh keeping liquid

Abstract

The invention discloses a dehydrating apparatus for an alcoholic group bactericidal and fresh keeping liquid. A technical scheme has main points that the dehydrating apparatus for the alcoholic group bactericidal and fresh keeping liquid comprises a cylinder container, a cover plate, a connecting bolt, a feed inlet, a feed valve, a high pressure air inlet, a high pressure air inlet valve, a high pressure air pipeline, a web plate, a granular alcoholic group bactericidal and fresh keeping liquid desiccant, a stainless steel basket, a transparent glass tube, an alcohol meter, a transparent glass tube top cover, a glass tube support, a discharging pipe, a discharge valve, a discharge hole and a support. The dehydrating apparatus for the alcoholic group bactericidal and fresh keeping liquid has characteristics of simple structure, convenient operation and fast dehydrating speed; after dehydration, the alcoholic group bactericidal and fresh keeping liquid with an alcoholic strength less than 80 has an alcoholic strength higher than 99.0%. The dehydrating apparatus for the alcoholic group bactericidal and fresh keeping liquid can conduct continuous production according to batches; the granular alcoholic group bactericidal and fresh keeping liquid desiccant in a saturation state after absorbing water can be dried for reuse; besides the dehydrating apparatus is suitable for dehydrating of alcoholic group bactericidal and fresh keeping liquid and other alcoholic products.

Description

technical field [0001] The invention relates to a dehydration device, in particular to an alcohol-based sterilizing and fresh-keeping liquid dehydration device. Background technique [0002] Deoxidation anti-mold preservatives are often used for food preservation. Some foods with high water content, such as fresh fish, fresh meat, fruits, vegetables, soy products, pickled products and birthday cakes, cannot be treated with deoxidation anti-mold preservatives. Preservatives or desiccants are used for fresh-keeping treatment, and alcohol-based extracts are often used for sterilization and fresh-keeping. However, the water content in conventionally produced alcohol-based extracts exceeds 20%, which directly affects the actual use effect. [0003] The dehydration processes used in the industrial production of ethanol include calcium oxide dehydration, azeotropic distillation, extractive distillation, adsorption, molecular sieve and vacuum dehydration, etc., but these industrial ...

[0002] Deoxidation anti-mold preservatives are often used for food preservation. Some foods with high water content, such as fresh fish, fresh meat, fruits, vegetables, soy products, pickled products and birthday cakes, cannot be treated with deoxidation anti-mold preservatives. Preservatives or desiccants are used for fresh-keeping treatment. Alcohol-based extracts are often used for sterilization and preservation. However, the water content in conventionally produced alcohol-based extracts exceeds 20%, which directly affects the actual use effect.

[0003] The dehydration processes used in the industrial production of ethanol include calcium oxide dehydration, azeotropic distillation, extractive distillation, adsorption, molecular sieve and vacuum dehydration, etc., but these industrial production processes are complex and require more investment A lot of equipment and a lot of expenditure are not suitable for the dehydration process of small-scale production of alcohol-based extracts
