Abstract
The invention aims to provide a novel method for preventing bacterial contamination on materials for producing sugar alcohol. According to process features of sugar alcohol production, a process means of depurating and purifying the materials by an ion exchange system is adopted by majorities, and treatments such as impurity removing, decoloration, filtering and the like are mainly carried out in a pre-period of ion exchange. The novel method is characterized in that an ultraviolet sterilizer or an ultrasonic sterilizer are connected behind the ion exchange system in a hermetical way to sterilize the material liquid subjected to the ion exchange, so that no chance of bacterial contamination on discharged materials behind the ion exchange system is ensured, and the quality of a product is effectively improved.
Description
Technical field
The invention belongs to biological sugaring field, be specifically related to a kind of new method that prevents the microbiological contamination of sugar alcohol production material.
Background technology
Prevent that microbiological contamination from being important content of biological sugar manufacturing industry, the product that particularly adopts biofermentation technique to produce, the importance of contamination preventing work is more outstanding.All must be in strict conformity with aseptic requirement except the configuration of the relevant devices of Zymolysis Equipment, air filtering system and medium sterilization system etc. and pipeline, if device structure and duct arrangement are unreasonable, make, install and do not note or careless manipulation during the fermentation, will make the fermentation liquid pollution microbes, cause product downgrade, output descends even can not get product.Because the continuity that biofermentation is produced is strong, the pollution problem of each link all can not be ignored in whole process of production, in the microbiological contamination of the mid-early stage of production process, tunning is consumed rapidly by the assorted bacterium of dye and can not get product.The later stage microbiological contamination will have a strong impact on the product separation extraction effect, and the microbiological contamination problem becomes one of principal element that influences product quality level, product yield and back process operations.
Along with development of biology and social great attention to food safety, some prevent that the sterilizing installation of food material production process and final products microbiological contamination is developed, but cost an arm and a leg, can not get popular popularization, limited the progress of biological sugar manufacturing industry.
Summary of the invention
The objective of the invention is production characteristics according to the sugar alcohol material, a kind of new method that prevents the material microbiological contamination is provided, to solve existing sugar alcohol production process complexity, the production cost height, the defect problem that the microbiological contamination probability is high, improve the exchange rate of ion exchange resin, improve the quality that improves product, enlarge the market application of product.
The present invention realizes like this:
Process characteristic according to sugar alcohol production, great majority have adopted ion exchange system to purify the process means of purification material, ion exchange early stage and be remove impurity, decolouring, filtration etc. mostly, characteristics of the present invention are after ion exchange system, airtight connection ultraviolet steriliser or ultrasonic sterilization device, feed liquid after the ion exchange is sterilized, guaranteed that the discharging after the ion exchange system do not have the microbiological contamination chance, effectively improved product quality.
Ultraviolet steriliser of the present invention or ultrasonic sterilization device equipment are the market common apparatus, invest little, take up an area of little, the reducing that only need carry out direct connection of necessary pipeline or pipeline connects, guarantee that the unobstructed of input and output material gets final product, its charging and discharging mode adopt upper and lower input and output material mode all can, keep its seriality.
Technology of the present invention is easy, and is simple to operate, reforms on the basis of original technology, do not increase too much investment, when improving labor productivity, effectively reduced the microbiological contamination probability of sugar alcohol production material, guarantees and improved the quality of product.
The specific embodiment: (is example with the production of oligofructose fluid product)
1, oligofructose production material saccharifying liquid heats about 80 ℃, presses 3～5% of dry and adds active carbon, and insulated and stirred was filtered about 30 minutes;
2, open ion exchange system, feed pressure≤0.3MPa, charging flow velocity be 3～6 times of resin volumes per hour, guarantee the PH and the electric conductance requirement of oligofructose discharging;
3, open airtight ultraviolet steriliser or ultrasonic sterilization device, material is carried out entering down road vacuum concentration operation after the sterilization treatment;
4, evaporation and concentration under the vacuum condition, temperature are no more than 80 ℃;
5, the oligofructose fluid product by obtaining with upper type meets national standard (GB/T23528-2009) fully.
Certainly, invention implementation method and the embodiment shown in the present invention is not limited to here, above-mentioned only is illustrative but not determinate, therefore in the variation and the modification that do not break away under the general plotting of the present invention, should belong within protection scope of the present invention.
Claims (4)
1. new method that prevents the microbiological contamination of sugar alcohol material.It is characterized in that: the combination technology of ultraviolet steriliser or ultrasonic sterilization device.
2. method according to claim 1 is characterized in that: after ion exchange system, and airtight connection ultraviolet steriliser or ultrasonic sterilization device, the youngster who reduces the material microbiological contamination leads, and improves utilization rate of equipment and installations, improves product quality.
