Process description
1)Impurity removal and cleaning: accumulation yard ---- pass the fresh potato raw materials through the hydraulicconveying trough, roll through the trough, remove the surface soil, enter the conveyor, convey it into the washing
machine, and pass the captured sand and gravel in the front, wash, By pushing the paddle lever, it is forced to
squeeze, rub, and remove the skin. It is lifted out through the rotating bucket at the tail and enters the spray
cleaning section. The water of the finished impurities - flows to the sedimentation tank outside the workshop –
standby after precipitation - supplementary water for potato washing machine circulation - or external discharge.
2) The surface layer of potatoes entering the spray system of the quantitative conveyor has been basically
cleaned by spray cleaning. After spraying by this system, and further collision and friction between materials,
friction between materials and the barrel wall - after high-pressure spray water - rinse clean —Automatically convey
the next step with the direction of rotation —Fresh potato cracking system
3) Crushing-cracking system: The cleaned materials are fed into the crushing system evenly through the quantitative conveying system. According to different materials, the proportion of material and water is adjusted.
There are 1-2 levels of crushing systems. The purpose of cracking is to free the starch to the greatest extent, so as to maximize the starch extraction without increasing the production of fine slag.
4) After the screening and washing system is crushed, the material is adjusted to a certain concentration of material and water, and sent to the screening unit through a pressure pump. Generally, multi-stage washing slurry is selected according to the material, and process water is added to the last stage of screening for washing. The water is carried out according to the principle of countercurrent washing, with less water consumption, low energy consumption, good washing effect, and the dry starch content in the residue is less than 3-5%.
5) The sand removal system is pumped into the sand removal system through the fine sieving slurry separated from the slurry and slag, and the sand particles in the slurry are further purified and removed.
6) The starch protein separation section - also called the juice water separation section, after purifying and removing sand with a certain concentration of the original slurry - enters the dejuicing separation unit, and after a certain factor separation unit - removes 70% of the juice, and enters the next stage for further purification. Effluent - into a sedimentation tank - or sewage treatment.
7) After the starch refining section passes through the dejuicing section - the crude starch slurry is washed in the multi-stage cyclone section to remove the remaining fine fibers, proteins and sugars, and control a certain concentration to reach the national standard refined starch standard slurry.
8) Dehydration section: configuration - centrifugal dehydration system or pressure dehydration or vacuum dehydration system: a certain concentration of refined starch slurry - enters the dehydrator to remove the water in it. The purpose of dehydration is to produce dry starch. The necessary section, remove 60-70% Moisture, try to get rid of starch - easy to dry starch - finished powder - this saves energy.
9) Starch drying system - after drying, cooling, packaging, storage and dehydration, the starch moisture is controlled between 34-40% and enters the starch dryer through the feeder for drying. The dryer heats the pure air to a certain temperature through a heat exchanger. (It must be at low temperature) After fully mixing with the dehydrated feed starch, it passes through the drying tube, mass transfer and heat transfer, fully mixed and contacted for 3-5 seconds to achieve the purpose of drying, the starch will not be gelatinized at a certain temperature, and the moisture is controlled within a certain requirement. The moisture content of the finished product can be automatically released to 18-20%. Then the fineness of the finished product is screened to the required value through the cooling system. The finished product is packaged and stored in the warehouse.
