Made In China sweet potato starch making machine/sweet potato peeling machine

 Zheng Zhou Sida Agriculture Equipment Co., Ltd has 25 years experience of Starch machine and producing the Starch, choose the high quality raw material in china and Foreign, equipped with the advanced production equipment. The product of peeling and washing machine, inclined rolling cage washing machine in the peer leading level and enjoy a good reputation. And has got more than ten National Patents.

 Zheng Zhou Sida Agriculture Equipment Co., Ltd has a group of experienced experts in Starch Industry and professional designers for Cassava flour processing machine, Who can be carried on various types of starch production line engineering design, installation,commissioning and training services.

As all machine are made of stainless steel and with very neat surfact to meet the increasing requirement from customers all around the world, we would be very carefully in aspect of packing and loading into containers. 

1. First nude for most parts.

2. Some needed to be pack into small box case first then load into containers.

3. If customers request all wood case packing, we do that if customers pay the extra cost.

See the picture as follows:

<1> Warranty time:1 year,after the warranty time,all the spare parts just ask for the cost price;

<2> We will supply the factory building drwaing or help the customer to build the factory after the order confirmed;

<3> The engineer will help the customer to install the machine and supply the free training;

<4> We will help the customer introduce the cassava starch customer

First process is transportation and cleaning

Collect the fresh sweet potato from stock ground, and transported by the conveyor belt to peeling machine for peeling and stone removing. After firstly remove the impurities on the surface, the sweet potato is transported into washing process. After washing twice by trough conveyor and roller, the sediment and impurities on the surface of Sweet potato have been basically removed, and peeling rate can achieve 80%. After cleaning process, the cassava will be transported into the crushing process

Second process is crushing:

Clean sweet potato will be broke into pieces by flying hammer type grinding machine in order to break the organizational structure of sweet potato. So that small starch granules can be disintegrated from the sweet potato root. Water plays the medium here. After twice crushing, sweet potato becomes slurry. The starch slurry after the first crushing can pass through 6-8mm puree sieve. The starch slurry after twice crushing can pass through 1.2-1.4mm puree sieve. The starch is basically free and becomes a mixture of pulp residue, then pumps it into the sieve for separation.

Third process is filtering

Residue slurry mixture passes through four vertical separator to be separated.sweet potato waste will be transported to the residue filed. And the starch extraction can already meet the standards of products only with protein, sediment and other organic and inorganic impurities to be proceeded in next process.

Fourth process is separating and concentrating

Starch will be pumped through the sediment remover to remove inorganic impurities. And then into the first disc separator, and then into the second disc separator. The main function of first disc separator is to remove protein, and the main function of second dis separator is to concentrate to be dehydrated. After the above treatment process, starch basically reached the requirements of the finished product. Following processes are dehydration, drying sections.

Fifth process is dehydrating

Concentration of starch out of disc separator is generally 18-20. After centrifuge treatment, the water content of starch deceased from 60% to 38-40%; dehydration of water( containing about 1 to 5% starch) continues to be concentrated in the disc separator. The wet starch will be transported to the air dryer treatment through the screw conveyor.

Sixth Process is drying and filtering

Air drier is a saturated steam which heats air through the heat sink, The starch will be heated by the hot air drying to achieve the dry purpose. Negative pressure, no dust and energy saving is throughout the system. After air drying, the starch water content is between 12-14% of the finished product standards. To ensure the fineness of the finished product can meet the standards. We also need to check the screen to prevent the starch after finished the process of agglomeration in the drying, so as to ensure that the final product can meet the standard.

Seventh process is packing

After been screening examination; qualified strach will be measured and packed. According to different requirements, we can pack them into 25kg or 50kg
