Sweet potato flour processing machine


Sweet potato flour processing machine

Sweet potato flour processing machine take Sweet potato as raw material to produce high quality Sweet potato flour. The whole process can be divided into seven steps, that is, raw material transportation, Sweet potato cleaning and washing, Sweet potato crushing, sand removal, dewatering, drying, sieving and packing.

The following is the detail introduction of Sweet potato flour processing step:

Step one - raw material transportation: to process Sweet potato, we need firstly use truck to transport raw Sweet potato from farmland to Sweet potato flour processing machine. Then it is stored on stockyard waiting for processing. The second time transportation occurs when Sweet potato flour processing starts, the Sweet potato on stockyard is conveyed by belt conveyor to cleaning machine.

Step two - cleaning and washing: In Sweet potato flour processing machine, cleaning and washing serves to remove the raw material surface adhesion mud sand. On the one hand, the stone, dirt skin and sand adhered to the surface of the raw material can be removed by the friction between the slurry blade and the raw material and between the raw materials; on the other hand, the raw material can be transported from the inlet to the outlet for discharging.

Spiral conveyor - this machine is installed between washing machine and crushing machine in Sweet potato flour processing machine. It has two functions. Firstly, due to it is designed with spraying device, the residual mud and sand on the surface of Sweet potato can be further removed; secondly, Sweet potato are transported to the crushing machine for processing.

Step three - crushing: Due to starch is mainly stored in the fleshy part of the Sweet potato tuber. Crushing serves to break down the tissue structure of Sweet potato so that the small starch particles can be separated from the root tubers smoothly. Crushing is one of the most important processes in Sweet potato flour processing machine, which is related to the flour yield and quality.


Step four - sand removal: quite a number of small Sweet potato flour processing machine is now developed from manual workshop. Sweet potato flour produced has high sand content and poor taste, which greatly affects the sales volume and price of Sweet potato flour, and thereof discourages the enthusiasm of producers.  company Sweet potato flour making process uses desander for sand removal, which can remove the sand content in the starch at a time, so that the product quality reaches the first-class.

Step five - dewatering: Large scale Sweet potato flour processing machine can choosing plate frame filter press for Sweet potato flour dewatering. It has the advantages of high press pressure, good corrosion resistance, easy maintenance, safety and reliability. For small Sweet potato flour processing machine and family-style workshops, hydraulic press can be used to achieve dewatering purpose.

Step six - drying: When drying starts in Sweet potato flour processing machine, wet Sweet potato flour and hot air enters into the drying pipe at the same time, fully contact with each other for heat exchange, so as to achieve the drying of Sweet potato flour. The drying strength of the starch flash dryer is large, and the wet Sweet potato flour can be dried just within a few seconds. It is characterized by low temperature, high drying speed, no contact with the outside world without pollution.


Step seven - sieving and packing: After drying, the starch enters the vibrating sieving machine to separate large particles, thus improve the fineness and quality of Sweet potato flour. Then Sweet potato flour processing machine uses automatic packing device to pack the processed Sweet potato flour into bags to avoid corrosion, ensure hygiene and facilitate transportation.

Because Sweet potato root tubers are extremely perishable, processing is important for Sweet potato's future.The Sweet potato processed products of Nigerian families and village workshops can be sold as convenience foods, especially Sweet potato flour can be used as a partial substitute for flour. In January 2005, the federal government of Nigeria implemented a policy of "10% Sweet potato flour must be included in bread", which increased the consumption of Sweet potato by 400,000 tons per year. In addition, Nigeria has set up the "President's committee on Sweet potato production and export promotion" to set an annual export revenue target of $500 million for Sweet potato to promote the development of Sweet potato industry, increase foreign exchange income and increase employment. Therefore establishing Sweet potato flour processing machine in Nigeria is promising and profitable. Henan  are professional in manufacturing Sweet potato flour processing machine, designing Sweet potato flour processing machine layout, installation and debugging Sweet potato processing equipment.
