AI Technical Summary
During the corn germ separation process, the prior art has problems of low filtration efficiency and poor separation effect, especially during the solid-liquid separation process, some corn particles will splash out with the liquid phase, affecting the separation effect.
The arc magnet and impurity filter are used in combination. When the corn kernels slide to the arc magnet, they are thrown out in parabolic form, and then fall to the impurity filter to increase the impact effect at the filter and improve the filtration efficiency. At the same time, through the installation of the solid-liquid separation and discharger, part of the liquid phase is discharged to the liquid phase treatment device through the liquid phase discharge pipeline to prevent corn kernels from entering the liquid phase treatment device and improve separation efficiency.
Through the combination of arc magnets and impurity filters, the filtration efficiency and separation effect are significantly improved, avoiding corn particles splashing out with the liquid phase, and improving the overall separation efficiency.

[0002] Corn deep processing is to use corn as raw material and use physical, chemical methods and fermentation engineering and other process technologies to deeply process corn. At present, corn deep processing products are mainly starch and starch sugar, alcohol, lysine, glutamic acid, citric acid, etc. In addition, DDGS, corn oil, protein feed, gluten feed, corn meal and other products that were originally considered by-products have also attracted people's attention. With the continuous innovation and expansion of domestic corn deep processing to deep processing, the application field of products is also expanding. For example, it extends to chemical and pharmaceutical fields.
[0003] In the process of corn germ separation, corn generally needs to be pretreated. Pretreatment generally requires iron removal, removal of broken particles, sulfurous acid soaking, etc., but in workshop production, only screening through a filter screen has the problem of low filtration efficiency, and the soaked corn needs preliminary solid-liquid separation. The existing device uses a conveyor belt for transmission and filtration. When the mixture falls to the conveyor belt, some corn particles will splash out with the liquid phase, which has a great impact on the separation effect. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a corn germ separation pretreatment device. Through the coordinated use of an arc magnet and an impurity filter, when the corn kernels slide to the arc magnet, they will be thrown out in the form of a parabola, and then fall to the impurity filter, thereby increasing the impact effect at the filter and improving the filtration efficiency; through the setting of a solid-liquid separation feeder, part of the liquid phase is discharged to the liquid phase treatment device through a liquid phase discharge pipe, and then the valve is opened, thereby preventing the corn kernels from entering the liquid phase treatment device and improving the separation efficiency.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] The corn germ separation pretreatment device comprises a storage bin, which is connected to a loading preparation bin through a loading impurity removal bin, which is connected to a crusher through a soaking tank, which is connected to a water squeezer through a germ separator, an arc magnet and an impurity filter are arranged inside the loading impurity removal bin, and a solid-liquid separation feeder is arranged below the soaking tank.
[0007] The arc magnet is used to absorb the iron impurities in the corn kernels, providing conditions for the falling corn kernels to form a parabola. The position of the arc magnet is adjustable and is determined according to the falling speed of the corn kernels.
[0008] An adjusting door is arranged between the storage bin and the unloading and impurity removing bin. The unloading and impurity removing bin is tilted. The corn in the storage bin slides down to the loading and impurity removing bin through the unloading and impurity removing bin by gravity.
[0009] The arc magnet and the impurity filter are both located on the bottom surface of the material unloading and impurity removal bin, the arc magnet is located on a side close to the storage bin, and an inclined baffle is arranged above the impurity filter.
[0010] An elevator is connected between the feeding preparation bin and the soaking tank, and a stirrer is arranged inside the soaking tank.
[0011] An arch breaker is arranged below the stirrer, a vertical wall below the soaking tank is tightened, and a vibrator is arranged outside the vertical wall.
[0012] The solid-liquid separation feeder is provided with a valve and a liquid phase discharge pipeline. The liquid phase discharge pipeline is located above the valve. A liquid phase discharge pipeline filter is provided inside the liquid phase discharge pipeline.
[0013] After the soaking tank treatment is completed, the valve of the liquid phase discharge pipe is opened to introduce most of the liquid phase into the liquid phase treatment device, and then the valve is opened and the corn kernels enter the crusher.
[0014] The purified corn from the corn storage bin is hydraulically transported to the soaking tank after iron removal, impurity removal and metering. The hydraulic conveying speed is 0.9-1.2 m / s, the ratio of corn to conveying water is 1:2.5-3, the temperature is 50±2 degrees, and the conveying water is recycled. The corn is soaked in the sulfurous acid solution in countercurrent, with a total of 8-12 soaking tanks. During the soaking process, the corn is stationary in the tank, and the soaking liquid is pumped to the previous tank while circulating in the tank, keeping the new sulfurous acid solution in contact with the corn with the longest soaking time, and the new corn in the tank is in contact with the soaking liquid that is about to be discharged, so as to maintain the best soaking effect. The soaking temperature is 50±2 degrees, the concentration of the sulfurous acid solution is 0.22-0.28%, and the soaking time is not less than 48 hours. The soaking liquid that has completed the soaking, that is, the dilute corn slurry, contains 5-9% dry matter and pH3.9-4.1, and is sent to the evaporation process to be concentrated into a corn slurry containing more than 45% dry matter. The corn at the end of the soaking contains about 43% water and is crushed.
[0015] The working principle of the utility model is:
[0016] The corn in the storage bin enters the unloading and impurity removal bin through the regulating door. After the falling corn kernels are iron-removed by the arc magnet, they fall to the impurity filter net in the form of a parabola for impurity removal. The inclined baffle is used to prevent small particles of impurities from flying out of the range of the impurity filter net, and then enter the feeding preparation bin; after metering, they enter the soaking tank through the elevator and are soaked in sulfurous acid solution. After the soaking tank is processed, the valve of the liquid phase discharge pipe is opened to introduce most of the liquid phase into the liquid phase processing device, and then the valve is opened, and the corn kernels enter the crusher, and then enter the squeezer through the germ separator for further processing. Among them, the arc magnet is used to absorb iron filings and impurities in the corn kernels, providing conditions for the falling corn kernels to form a parabola. The position of the arc magnet is adjustable and is determined according to the sliding speed of the corn kernels.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] By adopting the corn germ separation pretreatment device of the utility model, through the coordinated use of the arc magnet and the impurity filter, when the corn kernels slide to the arc magnet, they will be thrown out in the form of a parabola, and then fall to the impurity filter, thereby increasing the impact effect at the filter and improving the filtration efficiency; through the setting of the solid-liquid separation feeder, part of the liquid phase is discharged to the liquid phase treatment device through the liquid phase discharge pipe, and then the valve is opened, thereby preventing the corn kernels from entering the liquid phase treatment device and improving the separation efficiency.
