In the tinned food processing of routine,, generally all to bleach now, promptly handle with sulphite to it for the tinned food that makes acquisition outward appearance bright in colour is good, and then with SO residual on the semi-finished canned food
2Remove.At present both at home and abroad still continue to use traditional method and carry out desulfurization, this method adopts a desulfurizer, which is provided with inlet opening, osculum and spout hole, adds the semi-finished canned food of bleach in the groove, and its addition is at most desulfurizer 1/10 of the weight that is filled with water.Inject running water to desulfurizer during desulfurization, 1 ton/hour of the flow velocity of water, promptly with flowing water to the semi-finished canned food desulfurization.Because the tinned food kind is different, desulfurization time is also different, needs just to make more than 12 hours contained SO in the semi-finished canned food after the desulfurization at least
2The standard that concentration is up to specification.Its weak point is: the dead angle that 1. has water not flush in the desulfurizer, and the desulfurization lack of homogeneity, error can surpass Nippon Standard 30ppm.Last year China's cancelling power enterprise in have an appointment 10% enterprise be exactly because of SO in the product
2Detect abroad and exceed standard.2. the treating capacity of desulfurizer is few, only is 1/10 of its amount of being filled with water.3. the used time of desulfurization oversize, cause the production cycle long, efficient is low.4. consume too many freshwater resources.
Summary of the invention
The object of the present invention is to provide that a kind of desulfurization is even, efficient is high and the sulfur method of the semi-finished canned food of the bleaching of water-saving again.
The present invention improves the desulfurization process in the existing tinned food processing method, promptly in desulfurizer, establishes air jet system, quickens to remove the SO in the semi-finished canned food of bleaching through air-flow
2
The said semi-finished canned food of the present invention is greengrocery raw-food material such as vegetables, edible wild herbs, mushroom and bamboo shoot etc., enters into the material before the desulfurization process by the processing of the tinned food processing method of routine, abbreviates material below as.
What the used desulfurizer of the present invention was identical with prior art is also to be provided with inlet opening, osculum and spout hole, and different is in groove, also to be provided with air jet system.This air jet system is made up of connecting leg that is interconnected and air jet pipe; This air jet pipe upper end air blast outer with being located at desulfurizer links to each other; The lower end links to each other with the air jet pipe that is located at the desulfurizer inner bottom part; Above-mentioned air jet pipe is link to each other with the connecting leg pipe of remainder sealing of an end, and Qi Bishang is provided with some small through hole, and they are referred to as pore.The air jet pipe row that above-mentioned air jet pipe preferably is made up of many air jet pipes, this pipe row's moulding can be varied.Being preferably in the air jet system front portion is that the tube connector upper end is provided with air filter, and making the air that gets in the desulfurizer is pure air.
The concrete practice of the present invention is:
1. material is placed in the above-mentioned desulfurizer that fills running water material/water≤1 (weight ratio).
2. the air quantity size of air blast output is as the criterion so that material is stirred in groove.
3. jet time should be looked material size and shape and decide, and it is short to be prone to the used time of desulfurization material like strip, sheet, gets final product in the shortest 0.5 hour; It is long to be difficult for the used time of desulfurization material like whole bulk, and length can need 9 hours, and the jet time of ordinary material is 3-6 hour.
When the material in above-mentioned desulfurizer is jet, the one, but the disturbance material in desulfurizer, stir everywhere, actual is that material is stirred, and makes in the groove material desulfurization everywhere even; The 2nd, jetly force the material desulfurization, increased the gas-liquid exchange area greatly, make the SO in the material
2Most of taken away by gas, when bubble is floating break to the water surface after, the SO in the bubble
2Just get in the atmosphere SO after after a while in the material
2Major part is excluded through this approach.Fraction sulphur dissolves in the water in the material, SO in the water
2Exchange in the bubble through the very big gas-liquid of specific area, when the bubble disengagement water surface, this part SO
2Also can be discharged in the air.
4. in above-mentioned jet sweetening process, need long-time jet desulfurization material that just can be up to standard for those, preferably change the water in its place groove, to accelerate rate of sulphur expulsion, replacing in general 0.5-3 hour once gets final product.
The present invention compared with prior art has following advantage:
1, desulfurization evenly, no dead angle, error be 1ppm.
2, the desulfurization time weak point is not only enhanced productivity, but also has reduced the time of bacterial reproduction and foreign matter entering, has objectively improved product quality.
3, without the flowing water flushing, save a large amount of freshwater resources, also reduced production cost simultaneously.
4, a same groove treating capacity has increased 2-3 doubly, and specific yield is high, and cost descends.
