Corn syrup processing equipment

1) technological process of Corn syrup processing equipment Starch monosaccharification monosaccharification and a first discoloration filter an ion exchange for the first time to concentrate a second decoloration Filter a second concentrated product 2) operation points and steps for Corn syrup processing equipment

(1) starch raw materials require high purity corn starch, followed by potato starch and sweet potato starch.

(2) the slurry in the mixing tank, add some water first, under the condition of stirring, add crushed dry or wet starch, starch after feeding, to continue to join around 80 ℃ water, the starch milk concentration reached 22 ~ 24 baume degree (production glucose starch milk concentration of 12 ~ 14 baume degree), and then add in hydrochloric acid or sulfuric acid pH value of 1.8 - The slurry needs soft water, so as not to produce more phosphate and make it cloudy.

(3) the saccharification of the starch milk and the acid pump into the acid pressurized sugar can.

Feed and steam, feed, booster to (2.7 ~ 2.8) x 104 pa (142 ~ 144 ℃ temperature), in the process of boosting each booster 0.98 x 104 pa, valve all about 0.5 min, discharge cold air, to get rid of white smoke when closed, to make the mash, heated evenly, to step up to the required pressure to keep 3 ~ 5 min after sampling in time determine the DE value, up to 38 ~ 40, saccharifying terminated.

(4) after the saccharification ends, open the saccharifying pot to neutralize the saccharifying fluid.

Hydrolysis of hydrochloric acid, with 10% sodium bicarbonate neutralization, the hydrolyzer with calcium carbonate neutralization.

The calcium chloride produced by the former is deposited in the sugar solution, but the quantity is small, and the influence is not great.

The calcium sulfate produced by the latter can be removed during filtration.

Saccharification liquid and the purpose of, is not neutral to real the neutral point of pH 7, but most hydrochloric acid or sulfuric acid neutralization, adjust pH value to the freezing point of protein, protein coagulation filtration to remove, keep clear liquid sugar.

The best pH value of the protein in the sugar solution is 4.75, so it is generally neutralized to a pH of 4.6 ~ 4.8 - Neutralization, add 0.1% dry matter quality of diatomite as clarifying agent, diatomite dispersed in aqueous solution, negatively charged and positively charged proteins in the acid medium, thus clarifying the effect is very good.

(5) the decolorizing filtration and sugar liquid cooling to 70 ~ 75 ℃, the pH value to 4.5, to join in the physical quality of 0 · 25% of powder activated carbon, increases with the increasing and stir for about 5 min, pressure plate and frame filter or horizontal closed barrel type leaf filter filter off sugar filtrate.

(6) ion exchange will be the first decoloration of the purified sugar solution, and the removal of salt purification by the four ion exchange columns in the Yang Yin and one Yang.

(7) for the first time, the pH value of the purified sugar solution was reduced to 3.8 ~ 4.2, and the pump was put into the evaporating tank to maintain the vacuum level 66 - 661 Pa, and the heating steam pressure was not more than 0.98 x 10 - Pa, condensing to 28 ~ 31 baume, out of material, second decoloration.

(8) secondary decolorization of the second time is the same as the first.

The second decolorizing syrup must be returned to the non-activated carbon particles repeatedly, and the pH value will be revised to 3.8 ~ 4.2 - (9) the second enrichment and enrichment for the first time the same, just add sodium bisulfite before enrichment, sulfur dioxide in the sugar liquid is 0.001 5% ~ 0.004%, bleaching and color effect.

Evaporate to 36 ~ 38 baume, out of material, namely finished product.

3) enzymatic process Because the process of acid method is not easy to control in the degree of hydrolysis, the acid method is used to liquefy and enzymatic hydrolysis.

Liquefied the acid method, the control hydrolysis reaction, the DE value in 20% ~ 25%, the stop hydrolysis, and quickly.

Adjust pH value of 4.5 or so, temperature of 55 ~ 60 ℃ after adding glucose enzyme saccharification, until the DE value, then heat up, destroy enzyme, decoloring, ion exchange, concentration.

4) double enzyme process Acid enzymatic saccharification process can be well control fluid eventually DE value, but like acid method, there are still some shortcomings, equipment corrosion is serious, the use of raw materials can only be confined to starch, by-product generated in the reaction is more, the final syrup sweetness is not pure, so most of starch sugar producers to switch to enzymatic production process.

Its biggest advantage is that the liquefaction and saccharification are enzymatic hydrolysis, the reaction conditions are mild and the equipment is almost free of corrosion.

Direct use of raw food, such as rice (broken rice) as raw materials, is beneficial to reduce prod
