Abstract

The invention discloses a new process for separating and purifying a starch sugar mother solution in the chromatographic separation process of the starch sugar mother solution. The new process comprises the following steps: injecting a deionized water-free eluant into the starch sugar mother solution which is discharged from a syrup generation system through a centrifuge, performing chromatographic separation, performing decoloration, plate-and-frame filter pressing, ion exchange and five-effect evaporation, homogenizing under high pressure, drying, screening, and packaging into a finished isomaltose hypgather product. In the chromatographic separation process flow of the starch sugar mother solution, a filter process is increased to remove impurities such as scrap iron from condensed water; and through a temperature reduction process, the condensed water is processed into the eluant to replace deionized water. In the chromatographic separation process flow for separating and purifying the starch sugar mother solution, new processes such as filtration, temperature reduction, energy conservation and consumption reduction are innovatively applied, and the condensed water is processed into the eluant to replace the deionized water, so the product quality is improved and the production cost is reduced.

Description

A kind of Dian Fentang mother liquor separates novel process for purifying

Technical field: the present invention relates to a kind of Dian Fentang mother liquor separation novel process for purifying that the Dian Fentang mother liquor uses in chromatographic separation process.

Background technology: Dian Fentang has another name called glucose; Dian Fentang mother liquor English name hydrol or mother 1; Quor or greens, be after the crystallization starch massecuite through separate the sub product told behind the Dian Fentang crystal, also be simultaneously the big sub product of unique amount during Dian Fentang is produced; If primary crystallization Dian Fentang yield is 50%, then Dian Fentang mother liquor dry yield also is 50%.The Dian Fentang mother liquor is as the tall based raw material of the training of multiple leavened prod, like penicillium mould and other antibiotic fermentations raw material that rubs; Preparing alcohol, liquor; Make each seed amino acid, like Methionin; The system organic acid is like Hydrocerol A etc.; Fodder yeast and mixed feed.But below all be to utilize the Dian Fentang in the mother liquor to be effective constituent, remaining assorted sugar all remains in the fermented liquid because mikrobe can not be decomposed, and trailing wheel is that waste water is drained in vain, causes the energy to waste in a large number, and contaminate environment.And these are known as useful to the life body exactly sugar products of assorted sugar of the impurity in the Dian Fentang mother liquor, concentrate the spray-dried oven dry in back and can be made into the product innovation oligomeric isomaltose.

In the chromatographic separation process of Dian Fentang mother liquor in process for separating and purifying, need a large amount of vaal waters as eluent, and require water quality conductive less than cm, temperature requirement has increased production cost greatly at 55-60 ℃.Existing also have the discarded steam condensate of direct utilization to substitute vaal water, but because of steam condensation in pipeline produces a large amount of impurity, chromatography resin is had damage effect, gives it up because of having reduced quality product.

Summary of the invention: the present invention has overcome the drawback that ative starch sugar mother liquor exists in chromatographic separation process, and the water of condensation that spends after the removal of impurity is provided, and substitutes vaal water fully and separates novel process for purifying as a kind of Dian Fentang mother liquor that eluent uses.The objective of the invention is to realize: the Dian Fentang mother liquor that described syrup production system is discharged through whizzer through following technical scheme; Inject the vaal water eluent; Pass through chromatographic separation; Imitate evaporation through decolouring, filter press, IX, five then, after screening, be packaged into the oligomeric isomaltose finished product through high pressure homogenization, dry oven dry again; In the technical process of Dian Fentang mother liquor chromatographic separation, increased filtration process, remove the impurity such as iron filings in the water of condensation, through temperature reduction technology, be processed into eluent to water of condensation, substitute vaal water.

The invention has the beneficial effects as follows: because in the chromatographic separation technical process that the Dian Fentang mother liquor separate to be purified, innovation and application filtration, temperature reduction technology, remove impurity, be processed into eluent to water of condensation, replace vaal water, improve the quality of products.The other 30KW water pump of using of former vaal water eluent jar, change the 5.5KW water pump that adds for water of condensation eluent jar, per hour can practice thrift 19 degree electric weight, practice thrift power consumption, thereby reduced production cost.

Description of drawings: Fig. 1 is a process flow sheet of the present invention

Embodiment: embodiment 1: as shown in Figure 1; The Dian Fentang mother liquor that described syrup production system is discharged through whizzer; Inject the vaal water eluent; Through chromatographic separation, imitate evaporation through decolouring, filter press, IX, five then, after screening, be packaged into the oligomeric isomaltose finished product through high pressure homogenization, dry oven dry again; In the technical process of Dian Fentang mother liquor chromatographic separation, increased filtration process, remove the impurity such as iron filings in the water of condensation, through temperature reduction technology, be processed into eluent to water of condensation, substitute vaal water.

Embodiment 2: as shown in Figure 1, described filtration process is that water of condensation is filtered through accurate filter, removes impurity such as iron filings, is processed into the water of condensation eluent that substitutes vaal water.

Embodiment 3: as shown in Figure 1, described temperature reduction technology is with the water of condensation of removing behind the impurity, utilizes the heat conductivility of plate-type heat exchanger, follows stream through phreatic water, cool to 55-60 ℃ by 80 ℃ after, be processed into the water of condensation eluent that substitutes vaal water.

Embodiment 4: as shown in Figure 1, described the other 30KW water pump of using of former vaal water eluent jar, change the 5.5KW water pump that adds for water of condensation eluent jar.
