How To Produce Potato Starch?
Potato starch produce process: Potato - Hydro - Conveying - Secondary Cleaning - Cleaning to Stone Lifting - Crushing, Separation - Sand Removal - Concentration Refining - Vacuum Dehydration - Air Drying - Finished Packaging.
1, cleaning process and equipment
Mainly to remove the skin surface of the skin with the sediment, and wash away the material root of the epidermis, to stone cleaning machine is to remove the material in the hard miscellaneous. As the raw material for the production of starch cleaning, starch is to ensure the quality of the foundation, the more clean cleaning, the better the quality of starch. Delivery is the transfer of material to the next process, often also has a cleaning function. Commonly used to transport, cleaning, to stone equipment: hydraulic tank, spiral cleaning machine, oblique squirrel cage cleaning machine, pulp cleaning machine, to stone loading machine, (flat) squirrel cage cleaning machine, drum Cleaning machines, scraper conveyor and so on. According to the soil and material properties can choose some of them to achieve a combination of high cleanliness, easy to transport requirements.
2, raw material crushing and equipment
The purpose of the crushing is to destroy the material structure of the material, so that the tiny starch particles can be successfully separated from the root of the disintegration of the separation. The requirements for crushing are:
1. As much as possible to make the material cells rupture, the release of more free starch particles;
Easy to separate. Do not want the skin residue is too small, too much slag is not conducive to the separation of starch and other ingredients, but also increased the difficulty of separation of fine residue.
3, screening process and equipment
Starch extraction, also known as pulp residue separation or separation, is a key link in starch processing, which directly affects starch extraction rate and starch quality. After crushing the material is a small fiber, the volume is greater than the starch particles, the expansion coefficient is greater than the starch particles, the proportion of light and more than the starch particles, the crushed material to water as the medium, so that the separation of starch and fiber.
4, washing process and equipment
The washing and concentration of starch is carried out by means of a starch cyclone, which is divided into concentrated cyclone and washing and purifying cyclone. After sieving the starch slurry after the first through the concentrated cyclone, the bottom into the washing and refining cyclone, and finally to product quality requirements. The equipment is equipped with a full set of automatic control system, the use of high-quality cyclone and the optimal drainage program, can make the final cyclone excluded starch milk concentration of 23Be ', is the ideal choice for starch washing equipment.
5, starch dehydration
Potato starch often used vacuum suction filter dehydration machine. Can achieve automatic feeding, automatic dehydration, automatic cleaning.
6, starch drying
The air dryer is a hot air stream flowing at high speed to allow the wet starch to be suspended and dried during air flow. With high heat transfer coefficient, large heat transfer area, drying time is short and so on.
7, starch cooling and sieving packaging
After the starch is dried, the temperature is high. To ensure the viscosity of the starch, it is necessary to cool the starch rapidly after drying. After cooling the starch into the finished sieve, in order to ensure product fineness, yield under the premise of the last one into the packaging process.
