Technical Field

The invention belongs to the field of food processing devices, relates to a food polishing device, and particularly relates to a fresh rice squeezing polishing machine.

Background

The polishing machine polishes the surfaces of the extruded and formed fresh rice grains through a polishing roller or the interaction of polishing grains and the rice grains, thereby obtaining the appearance quality with glittering and translucent color, increasing the degree of finish of the rice, and improving the storage performance and the eating quality of the rice.

The existing polishing machine generally needs to be matched with atomizing equipment to spray atomized liquid into the polishing machine in the polishing process, but because the grains of freshly squeezed rice are small, the structure of the polishing machine is compact, the atomizing effect is poor, and further the produced rice grains are dark in color and luster, and the surface smoothness of the rice grains is poor. In addition, during the polishing process, the rice grains are pressed and contacted with each other, so that broken rice and powder cannot be avoided, but the conventional polishing device cannot separate the impurities from the finished rice, and the polished material is directly packaged, so that the quality of the finished rice is not uniform.

In order to solve the problems of surface glossiness of freshly squeezed rice, reduced content of broken rice and effective separation of impurities such as broken rice, some manufacturers research and develop new polishing equipment, but certain problems exist in the actual use process.

The use process of the invention is as follows:

when the invention is used, the fresh rice pressing particles to be polished are led into the screening cylinder from the feeding hole, and meanwhile, a corresponding number of polishing beads are led in according to the quality of the fresh rice (the number of the polishing beads depends on the volume of the atomized polishing liquid coated on the surface, and 20mL of atomized polishing liquid is preferably used for every 100g of rice to be filled in the polishing beads); then, a motor is started to drive the rotating shaft to rotate circumferentially, and when the rotating shaft rotates, the stirring rod drives the polishing beads and the fresh rice pressing particles to synchronously rotate until polishing is finished; and (4) after the polished fresh rice grains are led out from the discharge hole, screening the fresh rice grains through a vibrating screening machine, and collecting finished rice.

In the invention, the polishing process of mutual extrusion and vibration of the existing fresh pressed rice particles is optimized, and polishing beads are added into a polishing barrel. The polishing bead surface adheres to the thin solution of the moisture-resistant film and the atomized polishing solution to replace the existing atomized spraying device, so that the polishing bead is directly contacted with the freshly squeezed rice particles, and is matched with the structure of the rotating shaft matched with the stirring rod, so that the atomized solution coated on the outer surface of the polishing bead is more fully contacted with the freshly squeezed rice particles.

The slope surface formed at the discharge port can ensure that no dead angle exists in the polishing barrel, reduce the residue of the fresh rice in the polishing barrel, and improve the guiding amount of fresh rice grains after polishing.

The whole device is made of stainless steel materials and mainly comprises a polishing chamber and a broken rice separating device.

A polishing chamber: the wall of the polishing chamber is made of stainless steel materials (1-2mm in thickness), the total length of the polishing chamber is 1700mm, and the width of the polishing chamber is 400 mm; the length of the rotating blade is 100mm, and the width of the rotating blade is 50 mm; the length of the separation wall between the polishing grains and the polishing rice grains in the polishing chamber is 1300mm, and the width of the separation wall is 350 mm; the diameter of the polishing particle is 10 mm.

Broken rice separation device: the wall thickness of the vibration device is 1-2mm, the length is 800mm, and the total height is 600 mm. Is connected with the discharge hole. The lower end of the discharge port is 1036mm long, the upper end of the discharge port is 542mm long, a broken rice sieve is designed at the discharge port, and the size of the sieve pores of the broken rice is adjusted according to the diameter of the produced rice grains.

Aiming at the problem that the polishing chamber of the existing polishing machine is fixed, the polishing chamber of the polishing machine is in a drum type, the problem that the grains in the dead zone cannot be polished or part of the grains are polished finally due to the dead zone fixedly existing in the existing polishing chamber is solved, and the polishing rate of the product is improved.

In the polishing machine, the polishing particles are used for polishing the fresh pressed rice, so that the problem that the uneven surface of the fresh pressed rice is easily formed when the polishing shaft is used for polishing is solved, and the polishing effect is improved. The polished fresh pressed rice has smooth and bright surface and uniform and stable product. The two-layer liquid of the polishing particles is atomized polishing liquid and a moisture-resistant film dilute solution.

In addition, the drum-type polishing chamber is internally communicated with the moisture-resistant film dilute solution, the action principle of the solution is the same as that of atomized water in the atomizing chamber, and the aim of ensuring that the humidity on the surface of the polished fresh rice grains is stable and unchanged is achieved. The moisture-resistant film dilute solution is prepared from carrageenan and n-3 polyunsaturated fatty acid, is suitable for processing fresh rice eaten by infants, and the n-3 polyunsaturated fatty acid plays an important role in normal development of the infants and prevention of non-infectious chronic diseases; the reason for forming the carrageenan into the film is that the hot solution is cooled to form a film, so that the higher temperature of the fresh rice grains generated by friction in the polishing process can be reduced, and the moisture of the fresh rice is prevented from being heated and evaporated.

The action effect is as follows: in the polishing process, liquid in the polishing particles is combined with the fresh squeezed rice through small holes in the surface by the impact between the polishing particles and the rice grains, a film is formed on the surface of the fresh squeezed rice, and the lysine which is missing in the traditional grains is supplemented, and meanwhile, the moisture content of the fresh squeezed rice can be guaranteed not to be heated and volatilized due to the friction between the fresh squeezed rice and the polishing particles. The polishing time is changed according to the different diameters of the rice grains, and the polishing grains are recycled after the action, namely the humidity is less than 10%.

Operation and effects of the apparatus

The polishing chamber is composed of polishing particles, a rotating blade, a rotating device and a rotating shaft, and the wall of the polishing chamber is composed of a screen, so that the polishing particles are conveniently separated from the rice grains. The rice grains enter a polishing chamber driven by a roller rotating device to be fully contacted with the polishing grains, and the polished fresh rice grains enter the next processing stage. The broken rice passes through the broken rice sieve at the outlet, and the separation of the broken rice and the finished product is realized. And recycling the polished polishing particles. Not only improved the separation efficiency of polishing rice grain and broken rice under vibrator's drive in this export, also improved the export efficiency of polishing rice grain.
