Grains such as rice, soybeans, vegetables, and corn can be processed into a wide variety of foods by wet grinding. In the processing, the refiner is essential. The refiner is a stainless steel wet grinding device that is often used for wet grinding of certain materials in the food, sugar, pharmaceutical and other industries. Through the refining equipment, the material can be ground to a fineness of 80-100 mesh, which makes the product taste more delicate and more convenient to eat.
According to a mechanic, most refiners consist of a refining chamber, a transmission mechanism, an electric motor, and a base. When the pre-treated cereal material after washing, soaking, etc. enters the hopper into the grinding, and enters the relatively moving upper and lower sanding discs under the action of centrifugal force. Due to the combined effects of material impact, extrusion and shearing of the sand disc, the grain material is grounded from the inside to the outside, from coarse to fine, along the plane of the sand disc.
As we all know, the variety of cereal materials, hardness, size, etc. are different, which also puts different requirements on the refiner. In order to better meet the requirements of grinding and pulping of various cereal materials, the grinding pieces of different tooth shapes have been upgraded. The slurry enters the center of the cutting zone through two grouting pipes. Under the action of centrifugal force and grouting pressure, the pulping process is completed faster and better through the friction and extrusion of the grinding disc.
It is worth noting that in order to better ensure the normal operation of the refiner and to ensure the refining effect of the cereal materials, users need to pay attention to some problems. First, the correct installation and placement. It is necessary to place the equipment in a place where it is convenient to operate, and it is placed stably, and the tension of the V-belt is adjusted, and the coaxiality of the coupling is required, and each combination machine should work separately. The lines and switches must be insulated and the grounding wire must be firmly grounded to ensure safety.
Second, start the operation. Before starting the machine, it is necessary to check whether the bolts of each part are tightened. If there is abnormal noise after starting up, it is necessary to stop the inspection and correct the fault before it can work. At the same time, check whether the augers are normal, whether the transmission belt is worn, the degree of tension, and the like. In addition, the cereal material is placed in the hopper, and after the slurry is normal, a uniform amount of clean water is injected into the hopper.
Note that during work, the feed insert should be slowly opened, and the adjustment handle should be slowly screwed in until the material is ground to the required thickness, and the fastening hand wheel is locked, thus ensuring the cereal material. The fineness of refining is uniform. If the material is not processed to the required thickness, it can be finely ground again. In addition, it is strictly forbidden to open the cover and the hands should not extend into the material port to ensure safe operation.
Third, the refining is over. After the refining is finished, the refiner is thoroughly cleaned and dried in time, and the lid is opened and ventilated to prevent rust from being affected by water stains, and the cleaning is not timely. The residual slurry of the equipment breeds bacteria and microorganisms affect secondary use. In addition, a small amount of oil is added to the position between the bearing and the body to lubricate and prevent rust, so as to better ensure the normal operation of the refiner.
In summary, the refiner is one of the important equipments for rice and soybean processing, and is increasingly used by small agricultural and sideline products for processing and for home users. The grain material can make the product fineness meet the needs of different consumers through the refiner. In addition, the whole working channel of the refiner from feeding, grinding to discharging is made of all stainless steel to ensure the safety and hygiene of the refining, and thus ensure the quality and safety of the products. Of course, users should also pay attention to the operating specifications to ensure that the refiner is operating normally.
