Requirements of air drying equipment for material in sweet potato starch processing
In the sweet potato starch processing equipment, the air drying machine has a large amount of processing, fast drying speed, and will not cause pollution to the starch, compared with the traditional natural drying, the air drying machine has a very obvious advantage.Some small mills that traditionally process sweet potato starch also want to upgrade their equipment to buy air dryers, but there are also requirements for the materials that go into the air dryers.
Sweet potato starch processing equipment air dryer
Air dryer to adapt to a lot of materials, in addition to starch, there are: quaalzone, oxalic acid catalyst, titanium dioxide, iron oxide, sodium sulfate, phosphate powder, gypsum retarder and so on.
However, generally speaking, airflow drying equipment is only suitable for loose, small viscosity, finished products are particles and powder materials, block, sticky materials may block the airflow drying equipment pipeline, thus unable to operate normally.
Second, the water content is appropriate
In the processing of sweet potato starch, before the material enters the airflow drying equipment, it shall be dehydrated to keep the moisture content of the starch material at about 40%. At this time, the starch has been in powder form, and then transported to the airflow drying machine for drying.
Starch milk without dehydration is not directly into the air dryer, of course, in addition to the starch other materials must be dehydrated first, make the moisture content of about 40%, can enter the air flow I starch dryer drying.
