Description
Technical field
The utility model relates to HFCS production technical field, particularly relates to a kind of novel multitubular heat exchanger for HFCS production process.
Background technology
Fruit glucose syrup is a kind of natural sweetener of new development, and constituent is fructose and glucose, and be a kind of amylase of high sugariness, be the thick liquid of no color or smell, moisture-absorbing moisture-keeping performance is good.Main be used as nutritive sweeteners, also can be used for soft drink, bakery product, cold drink, tinned fruit, jam, jelly, salad mount flower, confectionery products and all kinds of breakfast goods etc.
The HFCS technological process of production is:
1, size mixing: in tune powder bucket, first add part water, add cornstarch under agitation, feed intake complete, continuing to add water makes starch milk reach normal concentration (30%), then adding hydrochloric acid, to be adjusted to pH value be 5.6-5.8.
2, saccharification: the starch milk mixed up, with acidproof pumping molasses sugar tank; Charging is complete opens steam valve boosting power to 2.8 about thousand grams/cm, keeps this pressure 3-5 minute.Sampling; With 20% iodine fluid inspection saccharification terminal, can neutralize by blowing when saccharified liquid meets iodine brownish red.
3, in and saccharified liquid proceed to neutralization bucket and neutralize, add quantitatively useless charcoal when starting to stir and make filter aid, progressively add 10% sodium carbonate liquor neutralization, when PH is 4.6-4.8, open outlet valve, be cooled to 60 DEG C immediately with the pump pellucid syrup that filter extensively leaches of being made a gift to someone by liquid glucose, after cooling, liquid glucose decolours.
4, decolour: pellucid syrup puts into decolouring bucket, adds qualitative activity charcoal with adding with mixing, decolouring mixing time must not be less than 5 minutes, and then delivers to filter, leaches clear liquid and is contained in storage bucket for subsequent use.
5, resins exchange: first time decolouring cleaner liquid is delivered to ion-exchange filter bed and carries out desalination purification and decolouring.Liquid glucose passes through, and after sun-four, male-female-the moon resin filter bed, in the sugared bucket of storage, aligns pH value to 3.8-4.2.
6, evaporate: after resins exchange, accurately mix up the liquid glucose of pH value, utilize and be pumped to evaporator, keep vacuum more than 500 millimetress of mercury, heating steam pressure more than 1,000 grams/cm, when sugar concentration is at about 45%-50%, must not get final product discharging.
7, isomerization: solid phase isomerase is filled in the insulation reaction post of setting, reaction temperature controls at 60 DEG C, and liquid glucose, by capital charging, flows through enzyme post, carry out isomerization reaction, then from discharging at the bottom of post, continued operation, also can by charging at the bottom of post, through enzyme post, from capital discharging.Because of enzyme activity be in best pH value time, can give full play to catalytic action, reaction speed is fast, time is short, and the sugar degree occurred that reduces side reaction is low, the isomery liquid glucose of gained of light color, easily refining, so the pH value size of liquid glucose should be determined by the model of isomerase used during isomerization.
8, secondary resin exchanges: the liquid glucose through secondary decolourization need carry out a resins exchange again, and method is the same, and the liquid glucose pH value finally flowed out is higher, and available hydrochloric acid regulates pH value to 4.0-4.5.
9, evaporation and concentration; Refining liquid glucose is concentrated to the concentration of needs through vacuum evaporating pot, obtain HFCS.Because glucose is easy to crystallization, in order to prevent syrup from occurring crystallization at lay up period, liquid glucose can not be allowed to be evaporated to excessive concentrations, and General Requirements is at 71%-77%(dry substance concentration) between.
Tubular heat exchanger (tubularexchanger) is a kind of heat exchanger most widely used in current Chemical Manufacture.It is primarily of compositions such as housing, tube sheet, heat exchanger tube, end socket, hydraulic barriers.In in the HFCS technological process of production, traditional tubular heat exchanger is used for the second stage of liquefaction flash waste heat and carries out heat exchange to chromatogram workshop section desalted water, and heat exchange is carried out in first phase liquefaction flash waste heat and evaporation section charging.In use procedure, due to the impact by condition such as evaporation charging and chromatogram desalted water flow etc., evaporation charging 40m
3/ h, temperature increase 5 DEG C, and desalted water charging 12m
3/ h, temperature increase 17 DEG C, in this heat exchanging process, still having amount of heat without making full use of discharge, causing great energy waste.
