Sweet potato starch production process

The sweet potato starch production process is mainly divided into cleaning, processing and drying. The whole process is coordinated by various sweet potato starch production equipment. The whole set of sweet potato starch production equipment includes dry screen, rotary washing machine, cutting machine, rasper machine, centrifuge sieve, disc separator, cyclone group, vacuum dehydrator , flash dryer.

Cleaning stage:

The cleaning stage is a very important section in the sweet potato starch production process. Its purpose is to clean the sand, weeds, small rocks and other impurities on the sweet potato raw materials. This stage is mainly completed by dry sieve and rotary washing machine, which can well remove the dirt and impurities attached to the surface of the sweet potato raw material.

 

Processing stage:

In the sweet potato starch production process, the main work of the processing stage is to crush, filter, purify and dehydrate the sweet potato. The sweet potato starch production equipment used in this stage includes cutting machine,rasper machine, centrifuge sieve, and disc separatior, cyclone group, vacuum dehydrator.

Fragmentation: This stage is mainly to grind and smash the sweet potato raw materials to release the starch granules in the sweet potato cells and increase the starch extraction rate. Henan Jinrui uses cutting machine and rasper machine to process the sweet potatoes. The cutting machine breaks the sweet potatoes into fine grains or small pieces and transports them to the file grinder to grind into sweet potato slurry.

Filtration: This stage is to filter the sweet potato starch slurry to remove the sweet potato fiber, mainly using a centrifuge sieve. The centrifuge sieve uses centrifugal force and gravity to make the large particles of fiber reach the edge of the sieve basket of the centrifuge sieve and are collected in the collecting chamber, while the small granular starch falls into the powder collecting chamber to achieve the purpose of separating starch and fiber.

Purification: The purpose of the purification stage is to increase the taste of the finished starch, which is an important step in the production of sweet potato starch, which is mainly completed by a disc separator and a cyclone group. Both use centrifugal sedimentation to purify, concentrate and separate starch, and refine and wash starch milk.

Dehydration: Dehydration is to make starch easier to be dried. Combined with the characteristics of sweet potato starch granules, Henan Jinrui generally uses a vacuum dehydrator to dehydrate sweet potato starch. The vacuum dehydrator adopts the principle of vacuum pump adsorption, using the pressure difference to make the starch adsorb on the drum, and through continuous vacuuming, the starch removes excess water, and then it is scraped off by a fixed scraper.

 

 Drying stage:

This is the final stage of the sweet potato starch production process. Wet starch cannot be packaged directly, so sweet potato starch drying equipment is needed to dry the wet starch. Henan Jinrui uses flash dryer, the main working principle is to use the heat exchange between hot air and wet starch to achieve the purpose of starch drying. The new flash dryer designed by Henan Jinrui adopts the principle of instantaneous drying, which can complete the drying task within 1-2 seconds, and the wet starch has been dried before it agglomerates.

what sweet potato starch processing equipment are needed in the automatic sweet potato starch production line?

 In recent years, due to the continuous excavation of the value of sweet potato starch, the demand for sweet potato starch has become more and more vigorous, but the efficiency and quality of traditional hand-made sweet potato starch have not reached people's needs. Therefore, Doing Holding-Henan Jinrui has designed and manufactured fully automatic sweet potato starch processing equipment to mass-produce sweet potato starch to meet the demand for sweet potato starch in various industries. So, which sweet potato starch processing equipment is needed in the automatic sweet potato starch production line? 

 

The process of producing sweet potato starch in a sweet potato starch processing plant can generally be divided into three steps: cleaning, processing, and drying. Processing can be divided into crushing, slag removal, purification, and dehydration. The automatic sweet potato starch processing equipment used in the entire production process includes cleaning equipment, crushing equipment, slag removal equipment, purification equipment, dehydration equipment, and drying equipment.

Automatic sweet potato starch processing equipment-cleaning equipment

The degree of cleaning of the raw materials by the cleaning equipment will affect the normal operation of the subsequent work and the quality of the finished starch. Therefore, Henan Jinrui uses a dry sieve and rotary cleaning machine for raw material cleaning. The dry sieve is mainly used to remove weeds and small rocks doped in the raw materials, and the rotary cleaning machine is used to clean the sand and other fine impurities on the surface of the raw materials. 

 

Automatic sweet potato starch processing equipment-crushing equipment

The purpose of raw material crushing is to free the starch particles in the sweet potato raw material. Therefore, the higher the degree of crushing of the sweet potato raw material, the higher the starch extraction rate. The sweet potato crushing equipment generally used by Henan Jinrui includes cutting machine and rasper. The cutting machine cooperates with the rasper for secondary crushing, first coarse grinding and then fine grinding, with high grinding coefficient, high raw material crushing rate and high starch free rate , So as to ensure high starch extraction rate. 

Automatic sweet potato starch processing equipment-fiber removal equipment

Fiber removal refers to the removal of the fiber components in the sweet potato starch slurry, thereby improving the taste of the finished starch. The centrifugal sieve and fine fiber sieve contained in the automatic sweet potato starch processing equipment are used for the screening and removal of sweet potato starch slurry. The effect of the gravity and centrifugal force of the slurry is used to achieve the purpose of separating the slurry and the residue, and to remove the fiber in the starch slurry.

 

Automatic sweet potato starch processing equipment-refining equipment

Refining is mainly to delicately wash the sweet potato starch milk to improve the purity of the sweet potato starch milk. The sweet potato starch purification equipment used in the general market has average technology, and the purity of the finished starch is average. Henan Jinrui uses an eighteen-stage cyclone to process it. The full-cyclone process is used to concentrate, recover and refine the sweet potato starch milk. The purity of the processed sweet potato starch can reach 23 Baume degrees. 

Automatic sweet potato starch processing equipment-dehydration equipment

The purified sweet potato starch milk cannot be directly sent to the sweet potato starch dryer for drying, otherwise it will cause agglomeration and bridging, and cause the operation of the sweet potato starch dryer to malfunction. Therefore, the starch milk needs to be dehydrated into wet starch. The common sweet potato starch dehydration equipment in the production and processing of sweet potato starch is a vacuum dehydrator, which uses the principle of vacuum suction filtration to dehydrate the starch milk to wet starch with a moisture content of about 40%. 

Automatic sweet potato starch processing equipment-drying equipment

The dehydrated wet sweet potato starch meets the drying requirements and is transported to the sweet potato starch dryer for drying. Jinrui's sweet potato starch dryer combines the characteristics of domestic and foreign drying equipment, and has a high heat exchange rate. It can complete a batch of sweet potato starch drying tasks in less than 2 seconds. In addition, Henan Jinrui's sweet potato starch dryer is also equipped with a negative pressure drying system, which can avoid the loss of dusty potato starch, thereby ensuring the output of finished sweet potato starch.

 The automatic sweet potato starch production and processing equipment used by Henan Jinrui is controlled by a numerical control computer from cleaning to finished starch drying, without manual input to actual operation, with small errors in the production process and stable quality of finished starch. Henan Jinrui, as a responsible starch processing equipment manufacturer, pays attention to the user experience, designs corresponding solutions for it, and customizes suitable sweet potato starch production and processing equipment.
