In addition to direct human consumption other than the potato, or the main raw material for starch processing. Large-scale production process of potato starch and similar small-scale production process, the process flow: potato - hydraulic conveyance - cleaning conveyor - 2 cleaning - cleaning stone go upgrade - smashing, separation - Desanding - concentrated refined - vacuum dehydration - air drying -- product packaging.
1, cleaning processes and equipment
The main materials are clear with the appearance of the cortex Zhanhua silt, and wash the skin to remove root material to stone washing machine is to remove materials in the miscellaneous hard. The production of starch as raw materials to carry out the washing is to ensure the quality of basic starch, cleaning the more the net, the quality of starch, the better. Transmission is to transfer materials to the next process, often delivered at the same time there is cleansing function. Commonly used in transportation, cleaning, go stone equipment are: hydraulic flow chutes, spiral washer, washing machine oblique squirrel-cage, leaf-type pulp washing machine, expected to go up stone washing machine, (Flat) squirrel-cage washing machine, turn tube washing machine, such as scraper conveyor. According to the soil and material properties were carried out to choose one of a number of combinations to achieve high net cleaning, transportation to facilitate the request.
2, raw materials and equipment to crush
The purpose is to crush destroy the organizational structure of materials, so that small starch granules from the tuber can successfully separated in the breakup. Smash the request is:
1. As much as possible so that the cells of the breakdown of materials, the release of more free starch granules;
2. Easy separation. Paper does not want to slag too small, too small and not conducive to skin residue of starch with other components of the separation and increases the difficulty of separation of fine slag.
3, screening technology and equipment
Starch extraction, also known as slurry residue separation or the separation of starch processing are a key aspect, directly affect the extraction rate of starch and starch quality. After crushing the material of the fibers are small in size than the starch granules, expansion coefficient is also greater than the starch granules, the proportion of light on the starch granules will be crushed after the materials, with water as the medium, so that starch and fiber separation.
4, washing process and equipment
Washed and concentrated starch starch hydrocyclone are to rely on to achieve, the cyclone is divided into enrichment and washing cyclone swirler refined. Through the screen after the first pass through concentrated starch hydrocyclone, at the end of flow entering the hydrocyclone washing refined, and finally to achieve product quality requirements. Equipment is equipped with a full set of automatic control system, using high-quality swirl tubes and pipes of the optimized program, so that the final level can be excluded hydrocyclone starch milk concentration of 23Be ', starch washing equipment are an ideal choice.
5, starch dehydration
Regular potato starch by vacuum suction filter dryer. Can achieve an automatic feeding, automatic dehydration, self-cleaning.
6, starch drying
Air dryer is the use of high-speed flow of hot air so that at one of the wet starch suspension, at air flow drying process. Has a high heat transfer coefficient, heat transfer area, drying time is short and so on.
7, cooling and screening of starch packaging
Starch by drying at high temperature, in order to ensure the viscosity of starch, starch required in the rapid cooling after drying. After cooling the starch into the finished screen, while ensuring product fineness, the output under the precondition of entering the final packaging process.
