Abstract
The present invention relates to a new process and a pH adjusting device for starch processing, belonging to the technical field of deep processing of agricultural products. The pH adjusting device mainly comprises a pH adjusting tank, an acid container, a flowmeter, an adjusting valve, a starch milk container and a stirrer. The pH adjusting tank is a cylindrical tank, and the stirrer is arranged inside the pH adjusting tank; the pH adjusting tank is connected with the acid container and the starch milk container by pipes, and one side of the upper end of the pH adjusting tank is provided with an acidimeter. The process comprises the following steps of: metering manually, feeding, stirring, observing, adjusting and detecting. Starch milk in the starch milk container and an acid solution in the acid container are respectively injected into the pH adjusting tank through a feed port; after uniformly stirring, the indicating value of the acidmeter is observed; and the flow rate of the acid solution is controlled through the adjusting valve, and the indicating value of the acidmeter is observed again until a correct value is indicated. The new process and the pH adjusting device for starch processing provided by the present invention ensures accurate addition of acid amount into the starch milk and has high safety, and the error of adjusted pH value is reduced from 1 percent or more than 1 percent to 0.1 percent or less than 0.1 percent. Meanwhile, the concentration, the whiteness, the spot and other indexes of starch are greatly improved.
Description
Technical field:
The invention belongs to deep-processing technical field of agricultural products, relate to the regulation and control of pH value in the starch milk.
Background technology:
Because local water quality shows alkalescence, pH value is higher mostly in the starch milk.In existing starch processing technology, be provided with acidometer in starch milk transport pipe front portion before the starch milk dehydration, and at same position installation acid solution loading hopper, after starch milk enters pipeline, according to the pH value that acidometer is measured, human metering injects acid solution from acid solution loading hopper adding acid solution or constant speed by flexible pipe, the acid solution amount of Jia Ruing is inhomogeneous like this, causes the pH value fluctuation of starch milk bigger.The acid solution outdoor storage is easy to volatilization and has unsafe factor simultaneously.
Summary of the invention:
The purpose of this invention is to provide a kind of starch new process for processing and PH adjusting device, with solve prior art manually or constant speed add inaccurate and open-air volatilization and the unsafe problem of being easy to of putting of acid solution of acid solution pH value.
It is to adopt special-purpose PH adjusting device that the present invention overcomes the above problems the scheme that is adopted, the PH adjusting device mainly by PH adjust jar, sour container. under meter, regulated valve, starch milk container and agitator are formed, it is the cylinder shape tank body that its PH adjusts jar, built-in agitator; Its PH adjusts jar by pipe connection sour container and starch milk container, and sour regulated valve, sour under meter and starch milk regulated valve, starch milk under meter are set respectively on the pipeline, and PH adjusts jar upper end one side acidometer is set; Starch milk in the starch milk container and the acid solution in the sour container inject PH respectively by opening for feed and adjust jar, after stirring, observe acidometer and show, control sour flow size by regulated valve, observe acidometer numerical value once more to exact value; Below PH adjusts tank, set out pipe material, regulated valve and under meter are set on the pipeline; Its processing step is as follows:
1, human metering:, calculate the acid amount that adds according to adding the starch milk amount in acid and about 1: 10000 ratio of starch.
2, charging: acid solution and starch milk enter PH through the mouth of pipe and adjust jar, observe under meter to calculated value.
3, stir evenly: 15-25 ° of angle rotation of agitator inclination stirs evenly.
4, observe: observe pH value displayed value on the acidometer.
5, regulate: regulated valve, control acid solution flow.
6, detect: the pH value of observing acidometer shows until exact value, according to the qualified starch milk product of detected result acquisition pH value.
7, discharging: regulated valve shows the control load according under meter.
Positively effect of the present invention is: guaranteed the accurate adding of acid amount in the starch milk, acid solution mixes with starch milk through pipeline, safe, adjust back pH value error by originally 〉=1% drop to≤0.1%, simultaneously indexs such as the concentration of starch, whiteness, spot are all had bigger change.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a PH adjusting device structural representation of the present invention;
1PH adjusts jar, 2 sour containers, 3 sour regulated valves, 4 sour under meters, 5 starch milk under meters, 6 starch milk regulated valves, 7 starch milk containers, 8 agitators, 9 acidometers, 10 discharging valves, 11 discharging flow meters among the figure.
Embodiment:
As shown in the figure; The PH adjusting device mainly by PH adjust jar 1, sour container 2. under meter 3, regulated valve 4, starch milk container 7 and agitator 8 are formed, and it is cylindrical tank that its PH adjusts jar 1, built-in agitator 8; Its PH adjusts jar 1 by pipe connection sour container 2 and starch milk container 7, and sour regulated valve 4, sour under meter 3 and 5 starch milk regulated valves, 6. starch milk under meter are set respectively on the pipeline, and PH adjusts jar 1 upper end, one side acidometer 9 is set; Acid solution in the starch milk container in 7 starch milk and the sour container 2 injects PH respectively by opening for feed and adjusts jar, after stirring, observes acidometer and shows, controls sour flow size by regulated valve, observes acidometer numerical value once more to exact value; PH adjusts a jar top and connects two opening for feeds, and upper fixed has agitator, and two opening for feeds top is provided with under meter, and the under meter front end is provided with valve.Concrete processing step is as follows:
The first step: human metering; In acid and about 1: 10000 ratio of starch, calculate the acid amount that adds according to adding the starch milk amount.
Second step: charging; Acid solution and starch milk enter 1 PH through the mouth of pipe and adjust jar, observe under meter to calculated value.
The 3rd step: stir evenly; The angles rotation of 20 ° of left and right sides of agitator inclination stirs evenly.
The 4th step: observe; Observe pH value displayed value on the acidometer.
The 5th step: regulate; Regulated valve, control acid solution flow.
The 6th step: detect; The pH value displayed value of observing acidometer obtains the qualified starch milk product of pH value to exact value according to detected result.
The 7th step: discharging; Regulated valve shows according under meter, the control load.
