Description
Technical field
The utility model relates to a kind of device of removing remains of pesticide in the fruit juice, specifically, relates to a kind of device of removing remains of pesticide in the fruit juice with resin.
Background technology
Along with food-safety problem emerges in an endless stream, food-safety problem is also paid close attention to more and more widely.Because a large amount of uses of agricultural chemicals in planting process, cause that the raw fruit that is used for fruit juice processing such as apple, pears etc. are all residual a harmful agricultural chemicals, as organophosphors such as acephatemet, metrifonate, organochlorine and pyrethrin pesticide.Therefore, in the fruit juice process, need to remove these residual agricultural chemicals,, bring and big hidden danger for the healthy of consumers in general if in the fruit juice process, can not remove remains of pesticide effectively.
Because the agricultural chemicals that the confusion of agricultural chemicals use, particularly some countries are prohibited in the continuation use, causes also happening occasionally as the remains of pesticide incident that exceeds standard of the inspissated juice of final products; And along with the raising of coherent detection standard, this type of incident will be more.As processing enterprise, owing to can't control, therefore can only set about from processing technology from the source, the innovation by technology prevents the harm of remains of pesticide to human body.
The juice processing technique key step comprises: the cleaning of raw fruit, choose fruit, squeezing, coarse filtration, pasteurize, enzymolysis, ultrafiltration, absorption, concentrate, pasteurize and can.For the removal of remains of pesticide in the fruit juice, mainly realize now by use adsorption step in above-mentioned technical process.
At present, adsorbing this step mainly is to be undertaken by the mode of macroporous absorbent resin absorption and charcoal absorption.
Charcoal absorption is by adding a certain amount of active carbon in fruit juice, after stirring and placing a period of time, activated carbon filtration is fallen.Because active carbon non-selectivity suction-operated, can better not adsorb most agricultural chemicals, so this process of active carbon that in fruit juice, adds, can't reach the purpose of removing remains of pesticide in the fruit juice fully, and because the adding of active carbon, can form certain damage to filter plant such as milipore filter, the active carbon of finishing using also is difficult to handle, and environment is polluted.
Macroporous resin adsorption is to adopt fixed-bed process, and by polymeric adsorbent, the remains of pesticide in the fruit juice can be by resin adsorption, to reach the purpose of removing remains of pesticide with fruit juice.
The whole process of macroporous resin adsorption technology comprises: replace (fruit juice replacing water), adsorb, replace (water displacement fruit juice) and regeneration several steps.
Remove remains of pesticide by macroporous absorbent resin,, obtained application more and more widely as a kind of important means.Polymeric adsorbent is to have highly cross-linked netted, porous, no ion-exchange group, molten insoluble organic polymer bulk material, polymeric adsorbent has special selectivity to organic matter, particularly organic non-electrolyte, it is to be undertaken by intermolecular force in adsorption process fully, no exchange interaction, chemistry and phase transformation reaction can not exert an influence to the physical and chemical index of fruit juice.
The resin adsorption effect is subjected to the influence of factors such as material liquid pH, temperature, and according to the basic principle of absorption, under the situation that feed liquid character is determined, low temperature helps the carrying out of adsorption process.
In fruit juice processing, the temperature of fruit juice all remains between 48-53 ℃, and the main cause of keeping this temperature has three: 1. enzymatic activity is higher, helps the thorough of enzymolysis; 2. help the maintenance of ultrafiltration flux; 3. preceding crust kills back fruit juice does not need too much cooling, and the fruit juice temperature was higher before fruit juice advanced evaporimeter, energy savings consumption.Therefore resin adsorption also is to carry out under this temperature as middle operation.
In the present resin absorption technique, adopt the pattern of fixed bed, remains of pesticide in the fruit juice is adsorbed removal, its whole process comprises as mentioned above: replace (fruit juice replacing water), adsorb, replace (water displacement fruit juice) and four processes of regeneration, at first fruit juice advances resin, with the moisture content top wash clean in the resin column, collecting evaporimeter after fruit juice comes out concentrates, after resin adsorption is saturated, stop into fruit juice, need water that fruit juice in the resin column is cemented out, do not have recovery value up to resin column outlet pol, stop, resin being regenerated with regenerative agent.
In the whole service process, there are two replacement process, this moment resin column in except fruit juice is arranged, the existence of water, so its actual feed liquid operating mode in addition is different with fruit juice, owing to contacting of fruit juice and water, can cause the fruit juice dilution, the remains of pesticide actual concentrations reduces, and material liquid pH raises, and this all is unfavorable for the absorption of resin to remains of pesticide.Replacement process for the second time particularly, adsorbed a large amount of remainss of pesticide on the resin, the adsorption capacity of resin can reduce greatly, resin and fruit juice have formed adsorption equilibrium, when water with resin column in fruit juice when displacement, because medium changes, cause not only that remains of pesticide can not thoroughly be adsorbed in the fruit juice, but also the remains of pesticide water that has adsorbed on the resin may be resolved, enter the evaporation and concentration operation and sneak in the finished product fruit juice, bring food security hidden danger, if but not to this part fruit juice displacement, then loss is huge again, brings the rising and the waste of cost.
Therefore, macroporous resin adsorption is because its alternative is adsorbed, and adsorption effect is better.But, owing to enter the remains of pesticide of fruit juice in the fruit juice processing, it all is water-soluble agricultural chemicals preferably, its at high temperature (the fruit juice temperature is generally at 48-52 degree centigrade) since molecular activity increase, be more prone to soluble in water, and rising along with resin adsorption remains of pesticide amount, the adsorption equilibrium of all the other feed liquids is easy to be broken, therefore very easily the displacement stage along with water enters finished product fruit juice (this moment, water was equivalent to a kind of weak parsing agent), it is not thorough to cause remains of pesticide to be removed, and brings more serious food security hidden danger
