Description

[0001] The present application relates to the technical field of food processing, in particular to a dehydration device for konjac flour production and processing. BACKGROUND

[0002] The traditional fine powder processing method is dry processing, that is, fresh konjac is washed, peeled, sliced, dried or baked, and then crushed by a crusher. The fine powder is separated from the ash impurities by air separation device according to the difference in particle size, hardness and toughness. This method has low purity and low yield, resulting in high production cost. In order to solve the problems existing in the traditional method, a wet processing method for konjac fine powder is developed, that is, the washed and peeled fresh konjac is added with a large amount of edible alcohol as a processing medium to be crushed and ground into slurry. After separation and dehydration, the slurry is dried. The fine powder obtained by this method has high yield, white color, high viscosity and low sulfur content, but the consumption of edible alcohol is large, resulting in high production cost. In order to reduce the consumption of edible alcohol in the production process, a patent with the patent number "991146689" and the patent name "wet processing method for konjac fine powder with water as medium" is proposed. The processing method is as follows: the pretreated fresh konjac is placed in a high-efficiency wet crusher and added with 3-5 times of sulfite color protection aqueous solution for crushing and separation. The fresh wet powder obtained by dehydration is directly transported to a rapid drying device or immediately added with 60-70% alcohol sulfite anti-swelling color protection liquid for anti-swelling and color protection. Then, the wet fine grinding and drying are carried out to obtain the purified konjac fine powder.

After the scraping is completed, the above-mentioned action is repeated, so that the straight gear 315 is engaged with the arc gear rack 319, and the scraping plate 308 is pulled back into the cavity 306 under the pulling action of the first return spring 313. At the same time, the material on the scraping plate 308 flows downward along the scraping plate 308 to the bottom of the centrifugal tank body 201, so as to be discharged outward through the discharge port. After the scraping is completed, the driving motor 301 is turned off by the controller.

[0029] This invention enables preliminary screening of materials upon initial entry. A stirring shaft 302 and a stirring paddle 303 are installed within the centrifuge tank 201. The stirring paddle 303 is U-shaped and includes a horizontal bar 305 and a vertical bar 304. A cavity 306 is provided within the vertical bar 304, and a rotating shaft 310 is rotatably connected within the cavity 306. Multiple cam structures 311 are provided on the rotating shaft 310. An opening 307 is provided on the vertical bar 304, and a scraper is slidably connected within the opening 307. The scraping plate 308 is integrally connected to the lifting plate 312. The lifting plate 312 and the cam 311 work together to lift the scraping plate. A first return spring 313 is provided between the lifting plate 312 and the inside of the cavity 306. This allows the rotation of the cam 311 to retract the scraping plate 308 into the cavity 306 or push it outward from the cavity 306. This allows the scraping plate 308 to work with the inner wall of the centrifuge tank 201 to scrape away material. During centrifugal dehydration, the scraping plate retracts into the cavity 306, achieving simultaneous stirring and dehydration, thus improving dehydration efficiency. The scraping is thorough, cleaning is convenient, operation is simple and easy, resource waste is avoided, and production efficiency is improved.
