Abstract
The present invention discloses a method for processing refined konjak powder by the wet method, in which water is used as media. The method is characterized in that pretreated fresh konjak are put in a high efficiency wet pulverizer, color protecting water solution of which the amount is 3 to 5 times of the amount of the pretreated fresh konjak is added into the pretreated fresh konjak, and the mixture is pulverized, separated in a parallel mode and dewatered, so that fresh wet powder is obtained; the fresh wet powder is directly delivered to a fast drying apparatus, or expansion inhibiting and color protecting solution is immediately added into the fresh wet powder to inhibit expansion and protect the color of the fresh wet powder; then, the fresh wet powder is ground in a wet and fine mode, and is baked, so that purified refined konjak powder is obtained. The present invention reduces alcohol consumption by 50% to 70%, and can realize that the processing for the first time is carried out in areas where konjak grows; the present invention can reduce the problems that a lot of mildew materials appear in the transportation process of fresh konjak, and the transportation cost is high, so that the cost of refined konjak can be reduced by above 30%.
Description
The present invention relates to a kind of processing of farm products method, especially a kind of is the medium konjaku fine flour wet processing method with water.
Traditional konjaku powder processing method is a dry process, being about to fresh Amorphophallus rivieri cleans, peeling, section, dry or dry again and pulverize with pulverizer, utilizing konjaku powder is that glucomannans particle and soot impurity are at the granularity weight, difference on hardness and the toughness, through pneumatic separation device they are separated, because glucomannans particle and the tight adhesion of considerable part ashes, the two separation is very difficult, often there is the smart powder of part to be removed with ashes, cause smart powder loss bigger, the ashes of considerable part is difficult to again separate from smart powder simultaneously, cause the smart powder purity of acquisition lower, the product utilization value descends, in order to reduce the konjaku powder loss and to improve konjaku powder purity, people develop with wet method processing konjaku powder method, be about to clean fresh Amorphophallus rivieri after the peeling and add a large amount of edible alcohols and make machining medium and pulverize and grind to form slurry, carry out row oven dry again behind the separating and dehydrating.With the konjaku powder harvest rate height that this law obtains, color and luster is white, the viscosity height, and sulfur content is low, but its consumption edible alcohol amount is big, produces one ton of smart powder and need consume about 1.5 tons of alcohol, has increased the konjaku powder production cost greatly, influences product in the market competitiveness.And production equipment is expensive complicated, and plant condition requires high.Simultaneously, be that dry method or wet method processing konjaku powder all exists and fresh Amorphophallus rivieri must be put together again through the concentrated processing site of transporting for long-distance, raw material freight charges height not only, and fresh Amorphophallus rivieri very easily goes rotten and loses, both reduce the income of taro farming, also strengthened the product cost of konjaku powder processing enterprise.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of konjaku powder recovery rate height is provided, quality is good, cost is low, be the medium konjaku fine flour wet processing method with water.Promptly be that machining medium is processed into common smart powder with bright taro with water.This method reduces alcohol consumption 50-70%, and can be implemented in the konjaku place of production and carry out processing first time, reduces fresh Amorphophallus rivieri a large amount of going rotten and the high problems of freight in transportation, makes the reduction of konjaku powder cost more than 30%.
Purpose of the present invention realizes by following technical proposals:
The present invention includes following technical process: the fresh Amorphophallus rivieri preliminary treatment is the clean surface water that dries of fresh Amorphophallus rivieri, the Ex-all epidermis is hindered impurity such as worm scar, terminal bud again, parallel pulverizing, separation, dehydration, oven dry, it is characterized in that pretreated fresh Amorphophallus rivieri places 3-5 times of sulphite of high-efficient wet-type pulverizer adding to protect the look aqueous solution and pulverizes as medium, it is the 100-200ppm sulfite solution that said sulphite protects the look aqueous solution.The parallel separation, dehydration obtains bright wet-milling, and bright wet-milling is delivered directly in the baker, keeps temperature of charge to dry under 50-70 ℃ of condition, is common smart powder.
Above-mentioned bright wet-milling also can add 60-70% alcohol sulphite immediately and press down the swollen look solution that protects and press down the swollen look that protects, addition is bright wet-milling: 60-70% alcohol sulphite presses down swollen colour protecting liquid=1: the 0.6-1.5 weight ratio, the wet fine lapping of row again, oven dry obtain the purifying konjaku powder.
It is formulated by 60-70% alcohol and color stabilizer that 60-70% alcohol sulphite presses down swollen colour protecting liquid, and color stabilizer is sodium sulfite or sodium pyrosulfite or any sulphite of sodium thiosulfate, and concentration is 100-200ppm.
Said high-efficient wet-type pulverizer is that charging aperture is provided with cutting edge, be equipped with double wedge and roll flute sheet on awl orchid and the garden fluted disc, both do relative operation, and relative rotation speed is at 4000-6000 rev/min, and being provided with filter screen, it is fed to the wet crushing mill that discharging can be finished in 5 seconds.
The common smart powder of konjaku can add 50-60% alcohol again after the swelling of look swelling liquid is protected in adding again, addition is 1.5-2.5 times, and the fine lapping of wetting, separation, dehydration, oven dry, dried fine lapping and grading obtain purifying refinement konjaku powder.
The present invention makes full use of the characteristics that effective constituent glucomannans particle can not occur dissolving more greatly in 10 seconds that mainly contain of konjaku under water condition is arranged; adopt and pulverize parallel separating and dehydrating fast; press down swollen colour protecting liquid by adding 60-70% alcohol sulphite and make it insoluble; reach its self-colored purpose of protection; the wet fine lapping of row again; separating and dehydrating; the dried fine lapping of row again after the oven dry; grading; obtain purifying refinement konjaku powder; or directly oven dry behind the wet-milling separating and dehydrating; directly obtain common konjaku powder; again by going wet fine lapping separating and dehydrating after the capable swelling of 20% alcohol sulphite swelling color stabilizer again; oven dry; and fine lapping; grading obtains the smart powder of purifying refinement.
From above-mentioned situation as can be known, the objective of the invention is to realize, one aspect of the present invention does not add organic medium alcohol in the wet-milling process, and use water as machining medium, greatly reduce the alcohol consumption in the konjaku powder production, make the alcohol of 1.5 ton of 95% concentration of one ton of purifying refinement of original production konjaku powder consumption reduce to the 500-700 kilogram.Process konjaku powder with this law simultaneously, wet crushing mill can be transported to the place of production, process on the spot in the konjaku place of production, skin slag beyond the konjaku powder is made compost nearby and the field, and being pressed down swollen color stabilizer, common konjaku powder or konjaku wet-milling and 60-70% alcohol sulphite transports to row processing again in the smart powder processing factory, reduced widely in the bright taro transportation and gone rotten, and it is original about 1/3 that freight volume also has only, and both increased the income of taro farming, cuts the waste, also reduced pollution to environment, and for smart powder manufacturing enterprise has reduced cost, the konjaku powder fine size that the present invention produces, viscosity height, colourity is white, and sulfur content is also low.It is a kind of konjaku powder processing method of economical and practical, high efficiency.
Fig. 1 is processing process figure of the present invention.
