The potato is weighed by the pound and stored in the potato yard. The potato is channelled through a stream of potato pumps to the stone machine, where it is separated from other heavy objects.
(2) go to stone/wash
The potatoes were then washed in the squirrel-cage cleaner. In order to achieve better cleaning effect, secondary cleaning machine is required. After washing, the potato is delivered to the storage hopper by tilting belt conveyor.
(3) separation of impurities
Floating impurities such as leaves, branches, wood and other debris will be removed by separating the grille. Dirty water (sewage) will be discharged through the sediment pool to remove the smaller impurities.
(4) discharge screw
The storage hopper should be stored for about an hour to produce the required potato raw materials. Specially designed discharge port connected to the unloading auger, the discharging screw speed is stepless adjustable, so you can through the screw to adjust production line production ability. The export of the spiral is connected to the grinder.
(5) file
Grinding efficiency due to the file (can get free starch percentage) for system must rate is vital, therefore has carried on the special design to file mill grinding efficiency as high as possible in order to achieve the file.
(6) in addition to the sand
The potato starch emulsion from the grinder is carried by the screw pump to remove the grains of sand.
(7) fiber extraction
From the removal of the starch emulsion from the sand unit to the extraction unit, the unit is integrated, including three conical rotating centrifugal sifting and fibre pumps and defoaming pumps. The fibers are washed and separated from the cytuses of the multistage cyclone in this stage 3 sieve. The separated fibers are dehydrated in the dewatering sieve of crisps.
(8) the refined
From the first stage centrifugal screen out the milk into the starch concentration level 16 swirl washing unit, process water from the pump into the other end of the vortex station of starch in the form of counter flow washing. The cyclone station can be divided into three parts, the first starch milk through the concentrated vortex standing juice concentrate, condensed milk into the behind level 13 of the starch after washing unit, while out of the overflow of cell SAP into recycling cyclone stood for recycling of containing starch. The starch milk from the swirling flow is pumped into a stainless steel starch milk tank with a blender.
(9) starch dehydration
From the vortex to starch milk moisture content is too big, can not go directly to dry, so you need to first to dehydration of starch milk, the starch in about 40% moisture content. Starch emulsion with starch from starch pump milk temporary storage tank to the vacuum dewatering machine groove, pipe connected to a water pipe in starch milk, with process water starch milk will be diluted to a certain concentration. Vacuum pump to form inside a vacuum negative pressure, when starch emulsion a contact vacuum drum, starch milk sucked on the raised, filtrate is sucked into the filtrate separation and filtrate pump away, filter cake by scraper scraping, using food grade conveyor belt conveyor into air drier in the feed hopper.
(10) starch drying and packing
The dehydrated starch cake is delivered through conveyor belts to the inlet of the dryer and enters the lift through the feeder. The heat exchanger of the air flow dryer is the steam heat exchanger. The wet starch is heated by hot air and the water evaporates. After drying, the starch is separated from the air in a cyclone. Use the wind seal at the bottom of the cyclone separator. The wet air is expelled from the cyclone and discharged into the atmosphere. The collected starch is transported by screw conveyor to the vibrating screen unit, and the coarser particles are sifted from the starches. Through sifted refined starch, it is carried to the starch bin, which is deposited and cooled. It is then delivered to the semi-automatic packaging machine to be packed into 25 kilograms of finished product.
