Abstract
Description
본 발명은 당밀의 칼슘(Ca∥)을 가열 산처리후 칼슘을 제거하는 방법에 관한 것으로, 당밀은 당분이의에 고분자 유기 비당분, 아교질상의(Colloid) 무기염등을 다량 함유하고 있으며, 아미노산 발효, 알코올 발효등 발효공업에서 당질원료를 광범위하게 사용하고 있다.The present invention relates to a method of removing calcium after heating and acidifying calcium (Ca∥) of molasses, wherein molasses contains a large amount of high molecular weight organic non-sugars, colloidal inorganic salts, and the like. Carbohydrate raw materials are widely used in fermentation industry such as fermentation and alcohol fermentation.
당밀의 조성을 보면,Looking at the composition of molasses,
수 분 16-20%Moisture 16-20%
유기성분의 당분 53.0-62.0%53.0-62.0% Sugars of Organic Ingredients
비당류 10-1%Non-saccharide 10-1%
무기성분 8.0-11.5%Inorganic Components 8.0-11.5%
이중 칼슘(Ca≠)은 산화 칼슘 형태로 0.6-1.5%로 포함되어 있어, 이 칼슘은 글루타민상 정제과정의 염산을 사용하는 반 중화 공정에서 글루타민산 결정 생성 속도를 느리게 하고 정제 수율이 저하되므로 이 칼슘을 제거하기 위해서는 종래의 여러가지 방법인 물리적 방법, 물리화학적 방법, 화학적 방법 및 기계적 방법등이 있는데, 물리적 방법은 가열처리하여 아교질 상태로 침전시켜서 제거하고, 물리화학적 방법은 가열처리후 산·알카리를 첨가하여 침전물을 제거 하며, 화학적 방법은 과인산 석회, 규산소다, 황산알미늄 등 침전제를 첨가하여 침전물을 제거하며 기계적 방법은 물리적 작용에 의한 것으로 원심력, 압여기 및 규조토등을 사용하여 침전물을 제거하는 방법등이 있으나, 이들의 방법들은 당밀내에 함유 되어있는 무기염류를 다량 제거하게 되므로 발효에 필요한 무기성분을 필요이상으로 제거하게 되므로 재차 무기물을 첨가하여야 하는 작업이 필요하고, 연속작업이 곤란할뿐 아니라 칼슘 제거율이 낮고 또한 침전물 처리시 당손실 이 많은 결점이 있는 바,Calcium oxide (Ca ≠) is contained in the form of calcium oxide, 0.6-1.5%, this calcium slows down the formation of glutamic acid crystals in the anti-neutralization process using hydrochloric acid in the glutamine phase purification process, and this yield is reduced There are various conventional methods such as physical method, physicochemical method, chemical method and mechanical method to remove the physical method. The physical method is heated and precipitated in gelatinous state, and the physical and chemical method is used to remove acid and alkali after heating. The precipitate is removed by chemical addition, and the chemical method is to remove the precipitate by adding precipitants such as lime, sodium silicate and aluminum sulfate. The mechanical method is by physical action. However, these methods can remove large amounts of inorganic salts contained in molasses. Therefore, the inorganic components necessary for fermentation are removed more than necessary, so the work of adding inorganic materials is necessary again, and it is not only difficult to continuously work, but also has low defects in calcium removal rate and high sugar loss in sediment treatment.
본 발명은 상기와 같은 결점을 해결하기 위하여 당밀을 20-40%로 희석한 후 60-80℃로 가열하여 당밀내에 함유되어 있는 산화 칼슘을 황산으로 pH 2.5-4.0되게 첨가하고 1-2시간 방치하여, 황산칼슘을 침전시켜 이를 고속원심 분리기로 제거하는 방법이다.In order to solve the above-described drawbacks, the molasses is diluted to 20-40% and then heated to 60-80 ° C to add calcium oxide contained in molasses to pH 2.5-4.0 with sulfuric acid and left for 1-2 hours. To precipitate calcium sulfate and remove it with a high-speed centrifuge.
본 발명의 공정을 간략하게 설명하면, 당밀을 20-40%로 희석한 후 60-80℃로 가열하고 황산으로 pH 2.5-4.0되게 첨가하고 1-2시간 방치한 다음 고속원심분리기로 분리하고 살균기에 보내어 살균 시킨후 발효조에 발효영양원으로 투입한다. 발효완료액을 반중화조에서 염산으로 pH 3.2되게 첨가한후 정제과정을 거친다. 탈칼슘 공정에서 조제시 가열온도를 80℃이상으로 하면 당밀이 끊을 위험성이 많아지고, 침전물량이 많아져 분리시 당손실이 많이 생기며 60℃이하로 하면 점도가 높아져 이송에 곤란하고, Ca∥침전량이 적다. 그러므로 60-80℃가 최적이고, 황산으로 pH 2.5-4.0으로 되게 하는 이유는 pH 4.0이상일때는 소량의 칼슘 침전물이 생기며, pH 2.5이하 일때는 당밀이 탄화되어 손실이 생기므로 pH 2.5-4.0의 조건일때가 제일 적당하다.Briefly describing the process of the present invention, the molasses is diluted to 20-40%, then heated to 60-80 ℃, added to pH 2.5-4.0 with sulfuric acid, left for 1-2 hours and then separated by a high-speed centrifuge and sterilizer After sterilization, it is put into fermentation nutrient source in fermenter. The fermentation broth is added to hydrochloric acid at pH 3.2 in a semi-neutralization tank and then purified. If the heating temperature is higher than 80 ℃ during preparation in the decalcification process, the risk of breaking molasses increases, and the amount of sediment increases, sugar loss occurs during separation. If the temperature is lower than 60 ℃, the viscosity becomes high and difficult to transfer. little. Therefore, 60-80 ℃ is optimal, and the reason to make pH 2.5-4.0 with sulfuric acid is that a small amount of calcium precipitate occurs when pH 4.0 or higher, and molasses is carbonized and loss occurs when pH 2.5 or lower, so conditions of pH 2.5-4.0 Is the best time.
따라서 본 발명으로 제거된 발효액은 정제 공정시 반중화에 필요한 산 사용에 있어서 품귀현상인 염산 대신하고 많이 생산되는 황산을 사용할수 있다. 그러나 칼슘을 제거하지 않은 황산을 사용할 경우 정제공정에서 황산 칼슘이 생성되어 결정작업에 작업실패를 초래하게 된다. 그러므로 발효전에 당밀내 칼슘을 제거하면 정제공정에서 염산대신 황산을 사용할수 있으므로 원가절감도 되고 정제 수율이 높아진다. 또한 pH 및 온도를 상기조건으로 조정하면 무기물을 재차 첨가할 필요성이 없는 새로운 방법이므로 상세한 것을 실시예에 따라 설명하면 다음과 같다.Therefore, the fermentation broth removed by the present invention can be used instead of hydrochloric acid which is a shortage phenomenon in the use of acid required for anti-neutralization in the purification process. However, if sulfuric acid without calcium is used, calcium sulfate is generated in the refining process, which causes a failure in crystal work. Therefore, if the calcium in molasses is removed before fermentation, sulfuric acid can be used instead of hydrochloric acid in the purification process, thereby reducing the cost and increasing the purification yield. In addition, if the pH and temperature are adjusted to the above conditions, it is a new method that does not need to add the inorganic material again.
[실시예 1]Example 1
필리핀산 당밀(당도 58% 혹 갈점조액 Ca∥6mg/g)을 연속 공정에서 당밀 1kℓ당 물을 0.931kℓ을 가하고 80℃로 가열한후 85%인 황산을 당밀 톤당 15kg을 가하여 pH 3.0으로 조정한 후 1시간반 동안 방치한후 고속원심 분리기로 분리시켜 황산칼슘인 침전물 7.5kg이 생성된다. 침전물 제거비율은 0.6%이며, 다음표는 본 발명의 실험결과와 일본 특허 소 31-3360호와의 대비표 이다.Philippine molasses (58% sugar or brown algae solution Ca ∥6mg / g) was added to 0.931kℓ of water per 1l of molasses in a continuous process and heated to 80 ° C, and 85% sulfuric acid was added to 15 kg per ton of molasses to pH 3.0. After leaving for an hour and a half, the mixture was separated by a high-speed centrifuge to produce 7.5 kg of calcium sulfate precipitate. Sediment removal rate is 0.6%, the following table is a comparison table of the experimental results of the present invention and Japanese Patent No. 31-3360.
[표][table]
인용발명(일본특허 소31-3360호)은 당밀을 B×55 부근으로 희석하여 60℃로 가열후 인산청등제[Ca(H2PO4)] 2을 0.05-0.5% 가하고 생석회를 0.1%정도 투입 침전제사용, 이 경우 당밀내의 무기염류를 제거하므로 다시 무기염류를 첨가해야 함(당밀 발효 경우)Cited invention (Japanese Patent No. 31-3360) dilutes molasses to near B × 55, heats it to 60 ° C., adds 0.05-0.5% phosphate cleaner [Ca (H 2 PO 4 )] 2, and adds 0.1% quicklime. Use of precipitating agent, in this case, removes inorganic salts from molasses, so inorganic salts must be added again (in case of molasses fermentation)
본 발명은 당밀내 칼슘을 70%이상 제거할 수 있으며 침전물중에는 타 무기염류의 배출이 거의 없으므로 별도로 발효 배양중 무기염류를 첨가할 필요가 없다.The present invention can remove more than 70% of the calcium in molasses, and there is almost no discharge of other inorganic salts in the precipitate, so it is not necessary to add the inorganic salts during fermentation culture separately.
