Embodiment Construction
[0025] The present invention is further described below in conjunction with accompanying drawing:
[0026] A processing technology for continuously extracting canna starch from canna taro, comprising cleaning and removing impurities, filing, sieving, concentrating, refining, dehydrating, drying and packaging steps (see figure 1 ), wherein: in the refining step, realize the separation of starch milk by the eight-stage cyclone, part from the feed stream of the third-stage cyclone and pass into the bottom cavity of the second-stage cyclone, from the first-stage cyclone Part of the feed stream of the fourth-stage cyclone is passed into the underflow of the third-stage cyclone, and so on. That is to say, part of the material flow entering the latter stage cyclone is separated, and the backflow is introduced into the bottom inner cavity of the previous stage cyclone to increase the pressure and flow rate of the underflow, keep the material flow unblocked, and prevent deposition and ...

The invention belongs to the field of starch processing and particularly relates to a processing technology for continuously extracting Canna edulis ker starch from Canna edulis ker and special equipment for the processing technology. The technology comprises steps as follows: rasping, sieving, concentration, refinement, dehydration, drying and packaging and is characterized in that in the refining step, starch milk is separated by multiple stages of cyclones, a part of material flow entering the later stage of cyclone is separated, back flow is introduced into an inner cavity in the bottom of the previous stage of cyclone to increase the pressure and flow rate of bottom flow, so that smooth material flow is kept, blockage is prevented, dynamic balancing of materials is realized, and the benign and stable operation state is ensured. The processing technology and the special equipment have the advantages as follows: feed separation and back flow pressurizing are proposed to solve the problems that starch rapidly settles during processing and easily causes blockage because of large particles of the Canna edulis ker starch, accordingly, dynamic balancing of a system is gradually realized, the problems that the starch rapidly settles during processing and easily causes blockage are completely solved, and the production continuity and stability are guaranteed; no power consumption is increased, and reduction of the production cost and improvement of benefits are facilitated.
Description
technical field [0001] The invention relates to the technical field of starch processing, in particular to a processing technique and special equipment for continuously extracting canna starch from canna taro as a raw material, and reaches the level of industrialized production. Background technique [0002] Starch is extracted from starchy plant roots and grains. Potatoes, sweet potatoes, and plantains are all root crops. The general process of extracting starch is as follows: Raw materials (including potatoes, sweet potatoes, etc.) are transported by hydraulic power, cleaned, transported to crushing, and then sieved, desanded, and then concentrated. Refined, vacuum dehydrated into wet starch, air-dried, and then finished and packaged. [0003] The Chinese patent number is 201110240788.X. The potato starch production process patent includes the following steps: (1) Fresh potatoes are sifted through a dry sieve to remove impurities, and then stored in the storage tank, and ...
