Technological process: potato - hydraulic conveyors - cleaning conveyors - secondary cleaning - cleaning to stone lifting - crushing, separating - removing sand - concentrate refining - vacuum dehydration - air drying - finished packaging.

Production process introduction:

1. Cleaning process and equipment.

It is mainly to remove the sediment from the outer layer of the material, and to remove the cuticle of the material root, to remove the hard clutter from the material. The cleaning of starch as raw material is the basis to ensure the quality of starch. The cleaner the cleaning, the better the quality of starch. Transportation is the transfer of materials to the next process, often delivered as well as cleaning function. 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 combined to achieve high cleaning and convenient transportation.

2. Raw material crushing and equipment.

The purpose of pulverization is to destroy the structure of the material, so that the small starch granules can be successfully separated from the root. The requirements for crushing are:

1. Make the cells of the materials as far as possible to rupture and release more free starch granules;

2. Easy to separate. It is not hoped that the skin slag is too fine, and the skin residue is not good for the separation of starch and other components, and it also increases the difficulty of separating fine slag. The domestic and foreign leading sorting pulverization. Immediately after the first level crush cutting material to filter, reduce retardancy, materials do not conform to the requirements to the second crushing, meet the requirements, no longer to make uniform fineness, lower power, controllable and grinding fineness, may be adjusted according to different material properties, is the ideal way of crushing starch processing.

3. Screening process and equipment.

Starch extraction, also known as slurry separation or separation, is a key link in starch processing, which directly affects the extraction rate of starch and the quality of starch. 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. The potato industry is fully panning - no pressure infiltration — The process (national patent) of the process of extruding successively multi-stage circulation (national patent). No pressure infiltration allows the pulp water to remain on the net through mesh holes. The starch in the fiber is further filtered by extruding, and the starch can be extracted with a small power and rapid process.

4. Washing process and equipment.

The washing and concentration of starch is accomplished by the starch hydrocyclone, which is divided into concentrated cyclone and cathartic cyclone. After screening, the starch slurry is firstly passed through the concentrated cyclone, and the bottom flow enters the washing and refined cyclone, and finally reaches the product quality requirement. The equipment is equipped with a complete automatic control system with high quality swirl tube and optimized drainage plan, which can eliminate the concentration of starch milk in the last stage of cyclone. Is the ideal choice of starch washing equipment.

5. Starch dehydration

Adopt vacuum suction and filter dewatering machine. The equipment also has the washing effect when the starch is dehydrated. It has the advantages of advanced structure, low energy consumption, good dehydration effect, easy installation and smooth operation. It can realize automatic feeding, automatic dehydration and automatic cleaning. It is the most ideal starch dewatering equipment in China.

6. Starch drying

The air dryer is used to suspend the wet starch in the process of air flow. It has the characteristics of high heat transfer coefficient, large heat transfer area and short drying time.

7. Starch cooling and screening package.

When the starch is dried, the temperature is high. To ensure the viscosity of starch, the starch needs to be cooled rapidly after drying. Our factory adopts cold air system, which has the advantages of low energy consumption, good cooling effect, smooth operation and large handling capacity. After cooling, the starch enters the finished product screen and enters the final packaging process on the premise of ensuring the fineness and production of the product.
