Technical Field
The invention belongs to the field of food cooking devices, and particularly relates to a low-temperature pulverizer for high-fat materials.
Background
Sesame, peanut, walnut and other high-fat materials are mostly crushed by adopting shearing or impact crushing equipment, when high-fat material particles are crushed to a certain size, the fat wrapped by cell walls is exposed and becomes liquid-state fat under the heat generated by shearing force or impact force, the liquid grease can be mixed and bonded with components such as fiber, starch and the like in the material, so that blockage can be caused, the crushing efficiency is low, and even the material cannot be crushed to the target granularity.
In order to prevent the problem that liquid grease mixes and coheres, some high grease materials adopt low temperature pulverizer to smash, and low temperature pulverizer adds the cold source in comminuted and cools down the material, ensures that the broken back grease of cell wall still is solid-state, can not be because the heat liquefaction of gathering in shearing or the crushing process to the problem of mixing cohering has been avoided, but low temperature pulverizer has following several problems: 1) The existing low-temperature pulverizers for food cooking all adopt liquid nitrogen as a cold source, so closed circulation of liquid nitrogen storage, supply and recovery needs to be completed, the structure is complex, the cost is high, and although a few low-temperature pulverizers for plant research at present adopt dry ice as the cold source, a large amount of CO released after the dry ice is mixed with materials is not available 2 The gas is discharged out quickly and the gas is discharged,can not be used for food cooking; 2) The current low temperature rubbing crusher accomplishes to smash the back and sieves through the sieve, need set up a plurality of sieves to different granules and carry out a lot of screening, selects separately the inefficiency.
Disclosure of Invention
The invention aims to provide a low-temperature grinder for high-grease materials, which adopts dry ice as a cold source and can quickly discharge CO while separating particles 2 The crushing of different degrees to the dry ice can be realized to gaseous, can adjust the proportion of dry ice and high grease material, simple structure, and is efficient.
The technical scheme adopted by the invention is as follows:
the utility model provides a cryogenic grinder for high grease material, including smashing the room, smash the indoor hammer mill mechanism that is equipped with, the import that smashes the room top communicates with material passageway and dry ice passageway respectively, the import department of material passageway and dry ice passageway is equipped with material hopper and dry ice hopper respectively, be equipped with spiral feeding mechanism in the dry ice passageway, the export intercommunication that smashes the room bottom has the separation exhaust chamber, separation exhaust chamber bottom intercommunication has a plurality of discharging channel, the air exhauster is installed to one side in the separation exhaust chamber, air exhauster the place ahead is equipped with the filter screen, discharging channel keeps away from the air exhauster in proper order and arranges and lie in between the export of filter screen and crushing room, the material hopper, all be equipped with the valve on dry ice hopper and the discharging channel.
Furthermore, the outlet of the discharging channel is hinged with a cover plate which can be opened outwards only.
Further, an insulating layer wraps the dry ice hopper.
The invention has the beneficial effects that:
1. during operation, high grease material gets into the material passageway through the material hopper and falls into and smashes the room, the dry ice gets into the dry ice passageway through the dry ice hopper and carries to smashing the room through spiral feeding mechanism, high grease material directly mixes and smashes through hammer type crushing mechanism with the dry ice in smashing the room, the dry ice cools down the material during crushing, guaranteed that the grease is still solid-state after the cell wall is broken, can not be because the heat liquefaction that gathers among the crushing process, thereby the mixture has been avoided cohering, high grease materialThe material is smashed into particles and then falls into a sorting exhaust chamber, the particles with different particle diameters fall into different long and short discharge channels under the dual action of suction force generated by an exhaust fan and self gravity, so that sorting is completed, and meanwhile, a large amount of CO released by dry ice is released by the suction force generated by the exhaust fan 2 And (4) discharging the gas. The low-temperature pulverizer adopts dry ice as a cold source, and quickly discharges CO while finishing particle sorting through suction force generated by the exhaust fan 2 The low-temperature crusher adopts the spiral feeding mechanism to convey the dry ice, the spiral feeding mechanism can crush the dry ice to different degrees, and the proportion of the dry ice and the high-grease material can be adjusted through the rotation speed, so that the large-particle materials such as walnuts and the like or the small-particle materials such as peanuts, sesames and the like can be uniformly mixed with the dry ice in a specific proportion, and the high-grease material is maintained at a lower temperature.
2. When the weight of the particles on the cover plate is accumulated to a certain degree, the suction force generated by the exhaust fan in the discharging channel is insufficient to support the weight, and the particles automatically fall from the discharging channel. The exhaust fan is combined with the hinged cover plate which can be opened outwards only, so that automatic discharging is realized, the structure is simple, and the cost is low.
3. The heat preservation layer plays the heat preservation effect, prevents that dry ice from absorbing heat too early to reduce cold source effect.
