The utility model is realized through following technical scheme: maltitol thin liquid continous way film concentrator; Comprise head tank, membrane component, fluid reservoir and filtrate tank; Described membrane component is provided with inlet, dialysis water out and concentrated solution outlet; Described head tank is communicated with the inlet of membrane component through force (forcing) pump A; Fluid reservoir is through the concentrated solution outlet of pipeline connection membrane component, and filtrate tank also is provided with a heat exchanger A through the dialysis water out of pipeline connection membrane component on the pipeline between filtrate tank and the membrane component.
Further, be provided with resistant to elevated temperatures NF membrane or resistant to elevated temperatures reverse osmosis membrane in the above-mentioned membrane component.
The inlet place of above-mentioned membrane component also is provided with a cleaning device, and the inside that is used for membrane component is cleaned, and cleaning device comprises water tank and force (forcing) pump B, and the inlet pipeline of force (forcing) pump B is communicated to water tank, and its outlet conduit is communicated to the inlet of membrane component.Also be provided with a heat exchanger B on the pipeline of membrane component and cleaning device, can make cleaning fluid remain under the suitable temperature, guarantee to clean up in the membrane component.
The beneficial effect of the utility model is:
(1) adopts resistant to elevated temperatures filter membrane; Directly use 70 ℃ the rare sugar alcohol liquid charging of reaching that produces in the last operation; Exempted the cooling link, and disposable concentration with maltitol brings up to 15%-18%, can directly be used for subsequent processing; So promptly can simplify technological operation, enhance productivity and reduce production costs;
(2) water electric conductivity of the dialysis water of this device is lower than 10us/cm, and COD has reached the standard of recycling less than 5mg/l, and on the pipeline of dialysis water, has added heat exchanger, and the heat that makes temperature reach 70 ℃ dialysis water obtains recycling.
