Problems solved by technology

[0004] The technical problem mainly solved by the present invention is the problem that the evaporator fouling in the beet sugar production process leads to the non-continuous production, and a method and device for softening beet syrup juice are provided. The production of beet sugar saves the stage of stopping production and cleaning fouling, and realizes the real continuous production

Embodiment 1

[0045] Backwashing process (16# process position): For the resin column switched out of the production process, first use 80-100 ℃ softened dilute juice for backwashing (inlet from the bottom of the column, and out from the upper part). Here, the resin is completely fluidized and washed Then use the low-temperature softening dilute juice to enter from the bottom of the column and exit from the top to cool the column, so that the temperature of the ion exchange resin is lowered to below 60 ° C, and the backwashed out material with insoluble impurities is refluxed and filtered The front tank, that is, the two-carbon retention tank, is filtered again in the clear juice filtration process. After backwashing, the resin column is switched to the regeneration process.

[0046] Regeneration process (13#—15# resin column): Use low-temperature NaOH to soften the dilute juice to regenerate the resin column, and the NaOH softened dilute juice enters the resin column, and the Na in the reg...

Abstract

The invention discloses a method for softening beet syrup. The method comprises the following steps: 1) a production process: enabling beet syrup to pass through a decalcification ion exchange resin column to obtain softened syrup; (2) backwashing: backwashing the decalcified ion exchange resin column which is saturated by adsorbing calcium ions; 3) regeneration process: regenerating the decalcification ion exchange resin column saturated by adsorbing calcium ions by using NaOH softened thin juice; and 4) leaching: leaching the regenerated ion exchange resin column by using the softened thin juice. When the softened thin juice obtained through the beet sugar thin juice softening method enters a subsequent evaporator and other procedures, the scaling phenomenon of the evaporator and crystallization sugar boiling equipment is reduced, the situation that production is stopped due to descaling of the evaporator and other equipment is avoided, continuous production of beet sugar is achieved, and labor cost is saved. And meanwhile, the service lives of the evaporator and the crystallization sugar boiling equipment are prolonged.

Description

technical field [0001] The invention relates to the technical field of beet sugar production, in particular to a method for softening beet sugar juice. Background technique [0002] In the prior art, the production techniques of beet sugar are mostly similar, generally as follows: obtaining sugar raw materials, exuding sugar, cleaning sugar juice, evaporating sugar juice, and boiling. For the cleaning of sugar juice, the production method commonly used in beet sugar factories is the carbonic acid cleaning method, that is, adding CO2 on the basis of adding excess lime 2 Gas, usually using two times of ash and two times of CO 2 Gas, by adjusting the pH of the sugar liquid, strengthen the mixing, reaction and coagulation of various colloids in the sugar juice, the fine suspended colloids in the sugar juice can be flocculated into coarse sediments, and the sediments can further reduce the particles and pigments Adsorption, thereby maximizing the removal of non-sugar substances...
