Embodiment 1

[0024] As shown in the drawings, the dietary fiber on-line sterilization device provided in this embodiment includes a flash dryer, and the flash dryer includes a screw feeder 1, a flash drying host 2, a primary cyclone separator 4, and a secondary cyclone separator. 5, cyclone dust collector 9, bag dust collector 11, induced draft fan 13 and control cabinet 14, the flash drying host 2 is equipped with a heater, condensate recovery system and inlet fan, and the bottom of the secondary cyclone separator 5 is equipped with an outlet feeder, the top of the rotary flash main engine is provided with a classification ring 3, the bottom of the cyclone dust collector 9 is provided with an ash hopper 10, the rear of the bag filter 11 is provided with an exhaust gas pipeline 12, and the secondary cyclone separator 5 is connected with the cyclone dust collector 9 are also provided with a sterilizer 7 and a steam heater. The front and rear parts of the sterilizer 7 cavity are respectively ...

Embodiment 2

[0037] This embodiment is basically the same as Embodiment 1, the difference is:

[0038] The bag dust collector 11 is adopted as a mechanical rotary reverse blowing dust collector.

[0039] During the dietary fiber preparation process, the air inlet temperature of the flash drying host 2 is 140°C, and the steam temperature in the sterilizer 7 is 150°C.

Embodiment 3

[0041] This embodiment is basically the same as Embodiment 2, the difference is:

[0042] During the dietary fiber preparation process, the air inlet temperature of the flash drying host 2 is 170°C, and the steam temperature in the sterilizer 7 is 160°C.

Abstract

The invention provides an online sterilization device and method for dietary fibers. The device comprises a flashing drying machine, wherein a cyclone dust collector and a sterilizer are sequentially arranged between a cyclone separator and a bag-type dust collector of the flashing drying machine; the sterilizer is internally provided with a feeding packing auger with a spiral structure; a feeding opening and a discharging opening are formed in the front and back parts of a cavity of the sterilizer; the feeding opening is communicated with a second-grade cyclone separator; a material collection mechanism is arranged below the discharging opening; a speed speeding motor for driving the feeding packing auger to operate is arranged at the outer end of the feeding packing auger; a steam heater is arranged outside the sterilizer. According to the scheme, the unification of a product production process and a sterilization process is realized and the cost of additionally arranging a microwave sterilization device is saved; a dietary fiber product is heated for short time through two different manners in the production process to keep the functional index of the product; the residual bean flavor in the product can be effectively removed; the flavor of the product is improved; the total bacterial count of the product is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of sterilizing equipment for food processing, in particular to an online sterilizing device for dietary fiber. Background technique [0002] Soybean dietary fiber products are widely used in industries such as jam, food processing and health products, and play a pivotal role in promoting human digestion and solid waste excretion. At present, the raw material used in the production of domestic dietary fiber is the leftovers produced by the production of protein isolate - wet bean dregs. There are no sterilization facilities in the wet bean dregs production and transportation section in the protein isolate production process, and the total number of colonies is very high (about 1 million); while in the prior art soybean dietary fiber production process, except in the flash drying process section, there are dry In addition to the high-temperature sterilization effect of hot air, the production line has no ster...
