No matter what the level of craft technology or the size of the processing scale, the entry threshold for cassava starch processing is low. Simple and casual processing methods can be used in rural areas. If you have home-grown sweet potatoes, you can prepare a powder machine, a large tank, and a cheesecloth bag to start processing.
However, if one wants to formally open a starch factory, one cannot rely on such primitive methods. A period of preparation and planning is required to formally enter the industry. So, what basic equipment is needed for a new user to start a sweet potato starch processing factory?
The pre-processing equipment mainly refers to the equipment that organizes and cleans the raw materials, including removing weeds, impurities, stones, earth, vines, woven bags, iron items, and other unrelated debris, to ensure the cleanliness of sweet potatoes and make subsequent crushing and filtering easier.
The pre-processing equipment mainly includes: dry washing and soil removal machine, oblique rat cage cleaning machine, paddle type cleaning machine, conveying feeding machine, and stone removing machine.
Crushing is to crush the raw materials and extract the starch. There are also other substances in the raw materials, such as coarse fibers, fats, and proteins. The purpose of filtering equipment is to filter out these substances and discharge them, so as to ensure the purity of starch.
The crushing and filtering equipment mainly includes: curve mesh extrusion powder making machine, file grinding machine, overflow machine, centrifugal sieve, micro filter machine, fine filter machine, sand and mud removal equipment, and so on.
The working purpose of concentration and separation equipment is the same as that of the sedimentation tank in the traditional process. It separates and removes yellow powder, oil powder, and pectin, and increases the concentration and precision of starch to achieve high-quality starch. This equipment is also only equipped in professional starch factories.
A large amount of water is used in the early stage of starch processing, and in the later stage, it needs to be dehydrated to fully dry the starch and achieve the purpose of storage and transportation. Otherwise, excessive moisture in the starch can cause spoilage and mildew.
The dehydration and drying equipment mainly includes: vacuum dehydration machine and air flow drying machine.
If the dried starch is to be used for bulk or weighed packaging, purchasing an automatic packaging machine is sufficient.
