Description

Technical Field

[0001] The utility model relates to a pulverizing device for salt production, belonging to the field of edible salt production equipment. Background Art

[0002] The process of producing iodized ordinary edible salt includes moisture intake, brine making, crystallization, salt collection and salt washing. After the salt washing step is completed, it needs to be dehydrated and dried. The drying is generally carried out by vibration drying on a vibrating drying bed.

[0003] In the existing vibration drying bed, during the vibration drying process, the material is fluidized on the drying bed through the vibration device, increasing the contact area between the material and the hot air; then, the hot air heats the material through the drying bed to evaporate the moisture in the material; at the same time, the continuous vibration of the vibration device can make the material continuously roll and diffuse on the drying bed, ensuring that the material is evenly heated and ventilated; finally, after a certain period of drying, the moisture in the material is completely evaporated to obtain a dry product.

[0004] In the process of drying edible salt, the smaller the salt particles are, the greater the possibility of solidification, because the larger the specific surface area, the larger the contact area between the salt particles and the air, and the easier it is to deliquesce and agglomerate. In addition, if there are many small salt particles between the large salt particles, the fine salt will repeatedly deliquesce and crystallize, causing the large salt particles to stick to each other.

[0005] The prior art public application number is 202122385291.9, and the name of the patent application is a crushing device for bamboo salt processing, which discloses that bamboo salt is put into a crushing box, and the crushing mechanism is started. The crushing mechanism crushes the bamboo salt, and the crushed bamboo salt falls on the filter plate. Small particles of bamboo salt pass through the filter holes on the filter plate and fall into the crushing box under the filter plate. Large particles of bamboo salt are blocked on the filter plate, and the vibration mechanism is started. The vibration mechanism accelerates the large particles of bamboo salt to slide from the filter plate to the lifting mechanism. The lifting mechanism lifts the large particles of bamboo salt to the top of the crushing mechanism and the crushing mechanism repeatedly crushes them, thereby improving the crushing effect and efficiency of the bamboo salt by the crushing device for bamboo salt processing.

[0006] However, compared with bamboo salt, which is tangible and regular in shape after being mixed, and can be rolled using double-axis rolling, the sea salt solidified during the drying process has different shapes and sizes. Edible salt has high crystallinity, light weight, and cannot be easily and directly rolled without pressure.

[0007] Therefore, the utility model provides a pulverizing device for salt production which first crushes by heavy plate pressure, then crushes, lifts and then crushes again. Utility Model Content
