The Modern Manufacturing Process Of Lotus Powder
Processing of lotus root - cleaning - crushing - filtering -Desiccant purification - concentrated refining - dewatering - drying - packaging - finished product.
The choice of raw materials: in order to ensure the flour yield, ensure the quality of starch, the processing of raw materials, should be neat in appearance, uniform thickness, color and luster is normal, the individual smooth surface is clean, no obvious flaws of mature fresh lotus root as a raw material.
Cleaning: the purpose of cleaning is to remove the sediment from the surface of the raw material, which is the key part of the work of the lotus powder, which is the purity and texture of the lotus powder.
Shredding and filtering: the purpose of crushing is to destroy the structure of the material, so that tiny starch particles can be separated from the root. Starch extraction, also called slurry separation or separation, is a key part of starch processing, directly affecting the starch extraction rate and starch quality. Solid ShuYe adopts crush - fully elutriation -- the pressureless infiltration - extrusion, in turn, multistage circulation process, can complete the starch with smaller power and fast process of extraction.
Bed cleaning cleansing. The main purpose is to further remove the sediment from the material.
Enrichment of refined. For a professional design, lotus root starch granules nature can enter enrichment of starches, and starch in the starch components completely separate, so that the final stage cyclone exhaust starch milk concentration to be 23 ', whiteness, purity, is the ideal choice of the starch washing equipment.
Dehydration. The concentrated starch pulp still contains more water, which needs to be removed from the material further to get into the drying section. Dehydration can be used with three feet dehydrator, large plant can choose to use scraper centrifuge.
Drying:
Drying by drying air, the drying machine is used to make the wet starch suspended in the flow through the hot, flowing heat, drying during the flow. It is characterized by high heat transfer coefficient, large heat transfer area and short drying time.
Starch cooling and sifting package
When the starch is dry, the temperature is higher, and the starch needs to be cooled quickly after drying to ensure the viscosity of the starch. Adopting the cold air system, the equipment has the advantages of low energy consumption, good cooling effect, smooth operation and large processing capacity. The refrigerated starch enters the finished screen and enters the final packaging process in order to ensure the product is fineness and yield.
