There are many ways to process sweet potato starch, but now more of them are automatic mechanized processing or semi-manual processing. The difference lies in the processing time and the simplification of processing steps. Edible sweet potato starch is divided into grades, so the configuration and price of sweet potato processing equipment are also graded.
Ⅰ. Requirements and process of sweet potato processing equipment
The sweet potato starch produced by the highly automated sweet potato processing equipment has high precision and purity, which can reach the industrial level, and is more used in the pharmaceutical and chemical industries. Such starch processing equipment is also relatively expensive, and the basic complete sets of equipment are all highly equipped.
Starch processing users in small starch factories and farmer workshops on the market that mainly process coarse starch can choose to configure medium-sized practical and economical sweet potato processing equipment. The investment is not too large, and it is expected to be between 100,000 and 200,000. The precision of this starch is not particularly high, but it can achieve the quality requirements of no adulteration, no taste, white color and fineness and uniformity. It is also sufficient for the edible grade starch of ordinary processing households.
The process of sweet potato starch processing is: Cleaning-Crushing-Filtering and purification-Degreasing and desilting-Concentration and refining-Vacuum dehydration-Drying.
The above is the process flow of a complete set of sweet potato processing equipment. If it is simple processing, there is no need for so many processing procedures, and the corresponding starch equipment that can be used is also less. Basically, it only uses washing, crushing, sedimentation and separation, followed by manual drying.
Ⅱ. Types of sweet potato processing equipment
Of course, because everyone's actual processing conditions are different, the requirements for starch quality and the degree of automation of sweet potato processing equipment are different. There are many options for the configuration and quantity of starch processing equipment. It can be equipped with only crushing and filtering equipment, or starch dryers are not required. These are all possible.
These are based on the purchase requirements, plus reasonable suggestions to match the sweet potato processing equipment. We can customize and flexibly match the specific ones.
The complete set of sweet potato processing equipment has the following types:
1. Sweet potato washer: there are different cleaning methods, which can be divided into dry cleaning machine, rubbing washing machine, and conveying cleaning machine;
2. Sweet potato crushing equipment: curved net extrusion type flour mill and overflow washing type flour mill;
3. Starch filtration equipment: fine filter, micro filter and centrifuge;
4. Starch purification and impurity removal equipment: desander and desilter;
5. Starch separation equipment: cyclone station;
6. Starch dehydrator: vacuum dehydrator;
7. Starch dryer: air-flow dryer.
