China customized stainless steel equipment for salt processing production line
The salt refinery process description
The crude salt is transported to the screw salt washing machine for the first washing, then crushed by roller crusher to get the salt with suitable size.This kind of salt will be washed by stirring washing machine and countercurrent washing machine for two or three times, and then get purified salt. The next step is to enter the centrifuge to remove most of the water. After this the salt will be dried by vibrating fluid drying bed for the drying to get the finished salt with 0.4% water content. During the salt transportation from centrifuge to vibrating fluid drying bed, there will be an iodized machine to add iodine into the salt. The final step is to packing the finished salt.
We has designed a unique washing system that is based in salt and brine countercurrent system in a custom designed screw. The washing process allows to identify soluble and insoluble impurities in raw salt using an advanced countercurrent brine system.
The washing and purification system is based in a mechanical principle of pure brine washing to increase purity of the salt crystals.
After the Washing process the salt goes into a centrifuge system with the latest centrifuge technology in order to further wash and purify the crystals while reducing humidity of the product in the process.
Salt centrifuges allow for precise liquid-solid separation process. A continuous separation process engineered to combine high availability with minimum maintenance.
we have developed our own Fluid Bed dryer technology, designed to provide continuous drying solutions for all types of salts (sea salt, rock salt, vacuum and/or lake salts). Manufactured in the best materials for resistance and avoiding corrosion.
Our drying system allows to dry and cool Salt using a combination of airspeed and mechanical motions to treat each particle efficiently and with minimum dust formation. By shacking the product up and down we achieve a uniform drying result with shorter time and lower temperature.
We has also engineered a crushing process to control the size of the Salt grain. With our horizontal roller crushers, the product goes in a vertical flow and the machine allows to control de crystal size. Our crushing and grinding machines are produced with high quality stainless steel and allow the operator to adjust the size of the crystal that will go out of the process.
we do offer a machinery range to add additives in Salt. It can be either Iodine, Fluor or anti-caking. The solution is a linear system that pulverizes the additive in the production a uniform way in order to obtain the Iodized Salt without any problem. Our process guarantees a perfect distribution of additives in the Salt crystals and meets the highest food and grocery standards required for food-grade distribution.

Main equipment-2 stage pusher centrifuge introduction
HP Series automatic salt production plant is a kind of perforated basket centrifuge, both continuous and effective. The mixture to be separated is fed through the feeding pipe and the distributor continuously and evenly into the first stage basket. Most of the mother-liquor in the feed, acted on by centrifugal force, departs through the sieves into the liquor-collecting casing where it will be discharged out of the machine. The first stage basket rotates and reciprocate, pushing the formed product cake into the second stage basket .The cake can have sufficient retardation in the centrifuge with being acted on by more centrifugal force, and therefore, the desired humidity of the cake can be guaranteed. Afterwards, the cake is continuously discharged out of the basket. In case of high purity for the solid product, the effective washing can be carried out in the centrifuge. If necessary, the washing agent and the mother-liquor can be discharged separately.
