1. produce the vapour phase feeding process method of 99.9% concentration raw spirit for one kind, its feature is as follows:

  • from alcohol steam and the raw material low pressure alcohol steam of 95% concentration of grain distillery'"'"'s thin alcohol recovery distillation tower, the alcohol steam of high pressure is generated after booster fan pressurization, high pressure alcohol steam is through the absorption of absorption tower adsorbs agent, vaporous water molecule in alcohol vapor is adsorbed, adsorb later alcohol vapor through alcohol condenser condenses and reactor product cooler cooling, produce finished product raw spirit;

    The faints of 85% concentration bottom adsorption tower enters light wine and enters the alcohol steam that recovery tower obtains 95% concentration, and alcohol steam directly enters booster fan, directly enters adsorption tower again, carry out cyclic production after pressurization after vapor superheater heating 130 ~ 145 DEG C.
