Description
Technical Field
The invention relates to a konjak powder processing method, in particular to a konjak purified powder processing method assisted by ultrasonic waves.
Background
The konjak is a perennial herb plant of the Araceae, is widely distributed in southwest mountainous areas, is a traditional food and a medical resource in China, contains various vitamins and mineral elements such as potassium, phosphorus, selenium and the like, is a food with low calorie and high dietary fiber, has high health care and medicinal values because of being rich in and only providing a food of water-soluble fiber glucomannan, and has various unique physicochemical properties such as water solubility, water retention thickening, stability, suspension, gelation, adhesion, film forming and the like, thereby having wide application value.
The processing method of the konjak purified powder at present is mainly characterized in that refined powder is prepared by using ethanol solution to be matched with chemical addition auxiliary agent for multiple times of immersion cleaning, separation, grinding and purification. For example, the invention patent with Chinese patent No. CN201210436345.2 discloses a method for preparing sulfur-free konjac gum, which comprises adding ethanol solutions with different concentrations three times respectively to fully soak and dissolve konjac fine powder, and washing with high-pressure cyclone. Although the method can recycle the ethanol, the production time is prolonged and the production cost is increased by three times of immersion cleaning, in addition, the ethanol is a volatile inflammable explosive substance, the sodium hydroxide is also a dangerous chemical, personal safety problems can be caused by improper operation or equipment damage during use, and the final quality of the product can be adversely affected because the sodium hydroxide is an alkaline substance. In addition, the concentration of the alcohol solution is increased, the frequency of immersion cleaning is reduced, and the defects exist, so that the production cost is increased and larger potential safety hazards are possibly generated due to the increase of the alcohol concentration.
Disclosure of Invention
The invention aims to provide a method for processing purified konjac flour by using ultrasonic wave assistance, which can solve the problems of high production cost, complex process, poor final product quality and high potential safety hazard of part of processes.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a method for processing purified konjac flour by using ultrasonic wave assistance comprises the following steps:
1) adding rhizoma Amorphophalli refined powder into prepared ethanol solution, stirring, and standing; wherein the concentration of the ethanol solution is 30-45%, and the mass ratio of the konjac powder to the ethanol solution is 1: 2-5;
2) carrying out ultrasonic treatment on the material liquid mixture in the step 1) by using an ultrasonic cleaning machine for 15-30 min;
3) carrying out solid-liquid separation on the liquid-liquid mixture after the ultrasonic treatment by using a continuous separator;
4) soaking and washing the separated fine powder for the second time by using an ethanol solution;
5) grinding the soaked and washed serous fluid mixture by a colloid mill for 2-3 times, wherein the grinding granularity is more than 120 meshes;
6) separating the ground slurry mixture again by a continuous separator;
7) centrifugally dewatering the separated material by using a centrifugal machine until no liquid drips out;
8) drying the dehydrated material by using a double-cone vacuum dryer, wherein the steam pressure is controlled within 0.2MPa, the temperature is 60-90 ℃, and the drying time is 120-180 minutes;
9) pulverizing the dried material with an ultrafine pulverizer to obtain rhizoma Amorphophalli purified powder with particle size of above 120 meshes.
The improvement of the technical scheme is as follows: and carrying out ultrasonic assistance by using an ultrasonic oscillator in the process of soaking and washing the fine powder.
Has the advantages that:
the invention provides a method for processing purified konjac flour by using ultrasonic wave assistance, and konjac powder is soaked in an ethanol solution for multiple times, so that the purity of the konjac powder is improved, the production and processing cost is reduced, the process time is shortened, and the production safety risk is reduced.
