Where Can Buy Potato Starch Production Line
Production methods Large potato starch production process is similar with small production technology, its technological process: potato - hydraulic transportation - cleaning - secondary cleaning - the stone crushing and separation - promotion - sand - processing - vacuum dehydration - drying - finished product packaging.
Clean technology and equipment
It is mainly to remove the dirt from the surface area of the material and remove the skin of the root of the material, and the stone cleaning machine is to remove the hard stuff from the material. Clean the raw material that makes starch, it is the foundation that assures starch quality, clean the more clean, the quality of starch is better. Transport is the transfer of materials to the next process, often delivered as well as cleaning. Commonly used transportation, cleaning, stone equipment are: hydraulic chute, screw cleaning machine, oblique squirrel cage type cleaning machine, the blade type cleaning machine, go to the stone material cleaning machine, (flat) cage type cleaning machine, rotary drum washing machine, scraper conveyor, etc. According to the characteristics of soil and materials, some of them can be selected for combination, which can achieve high cleaning and convenient transportation.
Raw material crushing and equipment
The purpose of shredding is to destroy the structure of the material, so that tiny starch particles can be separated from the root. The requirement for shredding is:
Break up the cells of the material as much as possible, releasing more free starch particles.
Easy to split. It is not hoped that the residue of the skin will be too thin, the residue will be too fine to separate the starch from the other components, and it will make it more difficult to separate fine slag.
Screening process and equipment
Starch extraction, also called slurry separation or separation, is a key part of starch processing, directly affecting the starch extraction rate and starch quality. Shredded material is fine fiber, the volume is greater than the starch granules, expansion coefficient is greater than the starch granules, and the proportion of light in the starch granules, after crushing materials, with water as medium, the separation of starch and fiber.
Washing process and equipment
The washing and concentration of starch is done by the starch spinners, which are divided into concentrators and washing refiners. After sifting through the sieve, the starch pulp is passed through the concentrator, the bottom flow into the washing refining cyclone, and finally the product quality requirement. Device is equipped with a full set of automatic control system, the exhaust pipe is made of high quality vortex tube and the optimization solution, can make the final stage cyclone of starch milk concentration to be 23 ', is the ideal choice of the starch washing equipment.
5, starch dehydration
Potato starch is often a vacuum filter. Automatic feeding, automatic dehydration and automatic cleaning.
6, dry starch
Air flow drying machines are used to make wet starch suspended in the flow of moisture through the hot, flowing heat, drying during the flow. It is characterized by high heat transfer coefficient, large heat transfer area and short drying time.
Starch cooling and sifting package
When the starch is dry, the temperature is higher, and the starch needs to be cooled quickly after drying to ensure the viscosity of the starch. The refrigerated starch enters the finished screen and enters the final packaging process in order to ensure the product is fineness and yield.
The starch residue produced by a small factory is not dried directly as a feed, and the starch residue in large factories is mostly dried. In order to save heat energy consumption, you can dehydrate the press first and then dry it with air dryer.
