Processing system and processing method of safe automatic coloring of picked fruits and vegetables

ActiveCN105285072AImprove colorImprove the appearance of commodity valueFruit and vegetables preservationAutomatic controlMicro computer
The invention discloses a processing system and processing method of safe automatic coloring of picked fruits and vegetables. The processing system comprises: a storehouse, and an ethylene control system and a CO2 control system, which are connected to the storehouse. The ethylene control system comprises an ethylene conveying tube, wherein an outlet port of the ethylene conveying tube is arranged in the storehouse; an inlet port of the ethylene conveying tube is connected to an ethylene gas tank; and the ethylene conveying tube is provided with a solenoid valve, and the ethylene control system further comprises an ethylene sensor arranged in the storehouse. The CO2 control system comprises a CO2 sensor, and an air-intake fan and an exhaust fan, which are arranged on two walls, opposite to each other, of the storehouse. The solenoid valve, the air-intake fan, the exhaust fan, the ethylene sensor, and the CO2 sensor are all connected to a first micro-computer control terminal. By accurately automatically controlling the concentration of CO2 and ethylene in the storehouse, a process of coloring picked fruits and vegetables is started, that is, the picked fruits and vegetables are safely ripened or de-greened. Color and luster of the picked fruits and vegetables is enhanced, and the appearance commodity value is increased.

Method and equipment for continuously refining liquid paraffin by virtue of by-product hydrochloric acid during chlorinated paraffin production

The invention belongs to the technical field of fine chemistry, and relates to a method and equipment for refining raw material liquid paraffin and by-product hydrochloric acid simultaneously during a continuous production process for chlorinated paraffin, wherein the equipment is an extraction tower. The method comprises the following steps of: continuously and manually extracting the by-product hydrochloric acid and the raw material liquid paraffin generated during the continuous production process for chlorinated paraffin, so as to improve the purity of the liquid paraffin entering in a chlorination reaction phase; and reacting the raw material liquid paraffin with free chlorine in the hydrochloric acid, so as to reduce the concentration of the free chlorine in the by-product hydrochloric acid. According to the method and the equipment disclosed by the invention, via the mutual extraction and reaction of the by-product hydrochloric acid and the raw material liquid paraffin, the contents of aromatic hydrocarbon, basic nitrogen, mechanical impurities and water in the liquid paraffin are reduced, the purity of the raw material liquid paraffin is improved, and then the colour of the chlorinated paraffin product is improved, and the colour numbers of platinum and cobalt are reduced to be less than 100; simultaneously, the raw material liquid paraffin can be reacted with the free chlorine in the by-product hydrochloric acid, so that the quality of the by-product hydrochloric acid is improved, and the content of the free chlorine in the by-product hydrochloric acid is reduced to 0.006 from about 0.015 originally after extraction.

Method of using reflux extraction technology for producing high dietary fiber foods

InactiveCN104172197AImprove colorImprove extraction yield and purityFood ingredientsBakery productsSodium carbonateReflux extraction
The present invention provides a method of using reflux extraction technology for producing high dietary fiber foods. The method comprises the following steps: acidizing: soaking bean dregs in clean water and adjusting the pH value to 3-5 with a hydrochloric acid solution of 0.5-1.0 mol/L; neutralizing: adjusting the pH value of the mixed solution to neutral with a NaOH solution of 0.5-1.0 mol/L; boiling under a high pressure: boiling the mixed solution under a high pressure at a temperature of 120 DEG C using a high-pressure sterilizing boiler for 1-1.5 hours; washing and dissolving: adding a sodium carbonate solution of 2-4% concentration into the boiled bean dregs and carrying out reflux extraction at a temperature of 80-90 DEG C; and drying by evaporation: 30 minutes after the reflux extraction, carrying out filtering, conducting precipitating on the filtrate with 3-4 times volume of ethanol as a precipitating agent, and drying the precipitated reagent at a temperature of 90 DEG C to obtain the soluble dietary fiber. According to the present invention, the dried soluble dietary fiber is utilized and added to the relevant ingredients to produce the functional dietary fiber foods. According to the present invention, the functional dietary fiber foods with high dietary fiber content, yellowish white appearance and good taste can be produced.

Resin special for decoloration of monosodium glutamate neutralizing solution

InactiveCN106632824AImprove colorGood regenerationRosinChemistry
The invention discloses resin special for decoloration of a monosodium glutamate neutralizing solution, and relates to the technical field of resin treatment. The resin is prepared from the following raw materials in parts by weight: 60 to 70 parts of trifluoroethyl methacrylate, 40 to 50 parts of allyl methacrylate, 30 to 40 parts of divinyl benzene, 25 to 35 parts of pore-forming agent, 10 to 15 parts of polyoxyethylene, 6 to 11 parts of polyacrylamide, 6 to 11 parts of pentaerythritol ester of hydrogenated rosin, 5 to 9 parts of active magnesium oxide, 3 to 6 parts of microcrystalline cellulose, 3 to 6 parts of glutinous rice flour, 2 to 4 parts of tricetanol phosphate, 2 to 4 parts of propylene glycol alginate, 1 to 2 parts of sesbania gum, 1 to 2 parts of initiating agent, 10 to 15 parts of ethanol and 200 to 250 parts of water. The prepared resin is special for decoloration of the monosodium glutamate neutralizing solution, organic pigments in the monosodium glutamate neutralizing solution can be effectively removed, and the decoloration rate is up to 99.5 percent or more, so that the color of a monosodium glutamate product can be remarkably increased; the regenerability is good, the output of wastewater is small, and regenerated resin still has stronger decoloration ability.
