Firstly, a smashing device in the system smashes and processes the lumpy brown sugar, when the smashing device works, the lumpy brown sugar is placed in a cutter shell, the smashing mechanism smashes and processes the lumpy brown sugar, and in the process of smashing and processing the lumpy brown sugar, the smashing mechanism also generates air flow when smashing and processing;

in the first working step, airflow enters the cutter shell from the first discharge hole through the right feed delivery pipe from the right air inlet pipe, then flows out of the second discharge hole, and then enters the storage device through the left feed delivery pipe; in the second working step, the airflow enters the cutter shell from the second discharge hole through the left air inlet pipe and the left material conveying pipe, then flows out of the first discharge hole, and enters the storage device through the right material conveying pipe. The first working step and the second working step are alternately performed.

The crushed brown sugar powder is carried in the gas flowing out of the cutter shell, the crushed large brown sugar particles are semi-finished products, and the large brown sugar particles cannot be driven by the airflow to flow out of the cutter shell and are continuously left in the cutter shell; simultaneously the brown sugar large granule is blown to the air current of alternant in the cutter casing, makes rubbing crusher construct and carries out crushing processing repeatedly to these brown sugar large granules, smashes into brown sugar powder with these brown sugar large granules, and brown sugar powder flows into storage device along with the air current and collects the storage.

The crushing device in the system utilizes airflow generated when the crushing mechanism crushes the lumpy brown sugar to take the crushed brown sugar powder out of the crushing mechanism and collect the crushed brown sugar powder; meanwhile, repeatedly conveying the large semi-finished brown sugar particles into a grinding mechanism by utilizing alternate air flow to grind until the large semi-finished brown sugar particles are processed into brown sugar powder; the collected brown sugar powder has small diameter and excellent quality.

Secondly, the anti-liquefaction device in the system can intermittently add high-pressure temperature-reduction airflow into the cooling airflow while continuously generating the cooling airflow to form mixed cooling airflow; the mixed cooling airflow can not only cool the grinding mechanism in the brown sugar processing flow, but also prevent the grinding mechanism from increasing the temperature due to grinding of the brown sugar for a long time, and further prevent the brown sugar from liquefying when contacting the grinding mechanism; meanwhile, the brown sugar powder can be prevented from being accumulated by the intermittent high-pressure cooling airflow.

Specifically, a power input device is connected to one end of the driving shaft in an external manner, the power input device can be a motor, the power input device drives the driving shaft to rotate, the first fan wheel and the second fan wheel are driven to rotate at the same time, and cooling airflow is generated, the flow rate of the cooling airflow generated by the first fan wheel is greater than that of the cooling airflow generated by the second fan wheel, so that the air pressure between the first fan wheel and the second fan wheel is greater than that of the air outlet, and the air pressure difference is generated; the intermittent air injection mechanism works under the action of air pressure difference and intermittently injects high-pressure cooling air flow to the air outlet.

Furthermore, the storage device in the system is used for collecting the brown sugar powder, the airflow with the brown sugar powder enters the first space from the collecting inflow pipe, the brown sugar powder is left in the first space after being filtered by the inner barrel, and the airflow passes through the inner barrel to the second space and then is discharged out of the collecting mechanism through the collecting outflow pipe; when the inner barrel collects brown sugar powder, the brown sugar powder attached to the inner part of the inner barrel can be cleaned through the power mechanism, and the inner barrel is driven to rotate, so that the brown sugar powder is prevented from being attached to the inner barrel, and the brown sugar powder can be continuously collected for a long time; meanwhile, the airflow can smoothly pass through the inner barrel all the time, and cannot be blocked by the brown sugar powder attached to the inner barrel, so that the collection efficiency is high; in the continuous collecting process, the resistance of the airflow in the collecting inflow pipe is small, and the normal work of the crushing device is facilitated.

Finally, the anti-solidification device in the system can remove moisture in the airflow and prevent the brown sugar powder from solidifying; when the moisture content in the air stream entering the milling device is too high, the brown sugar powder absorbs the moisture in the air stream, and the brown sugar is solidified from the powder into small particles again, which is not allowed. This device is located reducing mechanism's air inlet department, be equipped with liquid nitrogen gas in the air feed mechanism, liquid nitrogen gas sprays to cooling shell inside through the spray tube from the air feed mechanism, and liquid nitrogen gas is after leaving the spray tube, and the rapid vaporization is low temperature nitrogen gas.

The air flow enters the cooling shell from the cooling air inlet through the dehumidifying unit, and the dehumidifying unit can remove moisture in the air flow for the first time in the process; a small amount of moisture still exists in the airflow after the first water removal, the airflow is rapidly cooled under the action of low-temperature nitrogen, the small amount of moisture in the airflow is condensed into ice crystals, and the ice crystals are adsorbed by the dehumidification unit to finish the second water removal of the airflow; the content of nitrogen in the airflow is increased, so that the content of oxygen in the airflow is relatively reduced, and the effect of inhibiting the breeding of bacteria in the brown sugar is achieved.

Because the content of the first-time removed moisture is larger than that of the second-time removed moisture, the moisture is adsorbed by the outer surface of the dehumidification unit in the first-time removed moisture, and the moisture is adsorbed by the inner surface of the dehumidification unit in the second-time removed moisture; this results in a reduction in the quality of the water removal over time as the moisture content on the outer surface of the dehumidification unit is greater than the moisture content on the inner surface of the dehumidification unit. The dehumidification unit is connected with the air inlet in a sliding mode and can exchange the inner surface and the outer surface of the dehumidification unit; namely: after a period of time, the dehumidification unit slides into the cooling shell from the outside of the cooling shell, so that the exchange of the inner surface and the outer surface is realized, the water absorption capacity of the two surfaces is balanced, and the dehumidification quality is ensured.

Generally speaking, the system carries out crushing processing on the brown sugar blocks through the crushing device, and when the brown sugar blocks are crushed, the processed brown sugar powder is taken away by the back-and-forth alternate airflow generated when the crushing mechanism rotates for crushing, and the unprocessed finished brown sugar particles are continuously left in the crushing mechanism for crushing processing until the brown sugar particles are crushed into powder. The anti-liquefaction device directly cools the interior of the crushing device through two air flows, so that the brown sugar powder is prevented from being liquefied due to overhigh temperature; the storage device can separate and collect brown sugar powder in the airflow under the condition of extremely low influence on the airflow speed; the solidification prevention device prevents the brown sugar powder from being recombined and solidified into the massive brown sugar after absorbing water by removing the water in the air inlet flow; this system can be processed into brown sugar powder with cubic brown sugar, and the circumstances of brown sugar powder solidification and liquefaction can not appear in this system, does not have any cubic or large granular brown sugar that does not smash completely in the brown sugar powder of collecting.

Firstly, a smashing device in the system smashes and processes the lumpy brown sugar, when the smashing device works, the lumpy brown sugar is placed in a cutter shell 1, a smashing mechanism smashes and processes the lumpy brown sugar, and during the smashing and processing process of the lumpy brown sugar, the smashing mechanism also generates air flow when the smashing mechanism smashes and processes the lumpy brown sugar;

in the first working step, the air flow enters the cutter shell 1 from the right air inlet pipe 31 through the right material conveying pipe 3 from the first material outlet 11, then flows out of the second material outlet 12, and enters the storage device 5 through the left material conveying pipe 3; in the second operation step, the air flow enters the tool housing 1 from the left air inlet pipe 31 through the left feed delivery pipe 3 from the second discharge port 12, then flows out of the first discharge port 11, and enters the storage device 5 through the right feed delivery pipe 3. The first working step and the second working step are alternately performed.

The crushed brown sugar powder is carried in the gas flowing out of the cutter shell 1, the crushed large brown sugar particles are semi-finished products, and the large brown sugar particles cannot be driven by the airflow to flow out of the cutter shell 1 and continue to be left in the cutter shell 1; simultaneously the interior alternate air current of cutter casing 1 blows the brown sugar large granule, makes rubbing crusher construct and carries out the processing of smashing repeatedly to these brown sugar large granules, smashes into brown sugar powder up to these brown sugar large granules, and brown sugar powder flows into storage device 5 along with the air current and collects the storage.

Secondly, the anti-liquefaction device 4 in the system can intermittently add high-pressure temperature-reduction airflow into the cooling airflow while continuously generating the cooling airflow to form mixed cooling airflow; the mixed cooling airflow can not only cool the grinding mechanism in the brown sugar processing flow, but also prevent the grinding mechanism from increasing the temperature due to grinding of the brown sugar for a long time, and further prevent the brown sugar from liquefying when contacting the grinding mechanism; meanwhile, the brown sugar powder can be prevented from being accumulated by the intermittent high-pressure cooling airflow.

Specifically, a power input device is connected to one end of the driving shaft 42, the power input device may be a motor, the power input device drives the driving shaft 42 to rotate, and simultaneously drives the first fan wheel 43 and the second fan wheel 44 to rotate and generate a cooling airflow, a flow rate of the cooling airflow generated by the first fan wheel 43 is greater than a flow rate of the cooling airflow generated by the second fan wheel 44, so that an air pressure between the first fan wheel 43 and the second fan wheel 44 is greater than an air pressure of the air outlet 412, and an air pressure difference is generated; the intermittent air injection mechanism 45 works under the action of air pressure difference, and intermittently injects high-pressure cooling air flow to the air outlet 412.

Furthermore, the storage device 5 in the present system is used for collecting the brown sugar powder, the airflow with the brown sugar powder enters the first space 57 from the collecting inflow pipe 54, after being filtered by the inner barrel 56, the brown sugar powder is left in the first space 57, and the airflow passes through the inner barrel 56 to the second space 58 and then is discharged out of the collecting mechanism through the collecting outflow pipe 55; when the inner barrel 56 collects the brown sugar powder, the brown sugar powder attached to the inner part of the inner barrel 56 can be cleaned through the power mechanism 6, and the inner barrel 56 is driven to rotate, so that the brown sugar powder is prevented from being attached to the inner barrel 56, and the brown sugar powder can be continuously collected for a long time; meanwhile, the airflow can smoothly pass through the inner barrel 56 all the time, and cannot be blocked by brown sugar powder attached to the inner barrel 56, so that the collection efficiency is high; during the continuous collection process, the resistance to the airflow in the collection inflow tube 54 is low, facilitating proper operation of the crushing device.

Finally, the anti-solidification device in the system can remove moisture in the airflow and prevent the brown sugar powder from solidifying; when the moisture content in the air stream entering the milling device is too high, the brown sugar powder absorbs the moisture in the air stream, and the brown sugar is solidified from the powder into small particles again, which is not allowed. This device is located reducing mechanism's air inlet department, and the gas supply mechanism 8 is equipped with liquid nitrogen gas, and liquid nitrogen gas sprays to cooling shell 71 inside through spray pipe 75 from gas supply mechanism 8, and liquid nitrogen gas is after leaving spray pipe 75, and the rapid vaporization is low temperature nitrogen gas.

The airflow passes through the dehumidification unit 74 from the cooling air inlet 72 and enters the cooling shell 71, and in the process, the dehumidification unit 74 can remove moisture in the airflow for the first time; a small amount of moisture still exists in the airflow after the first water removal, the airflow is rapidly cooled under the action of low-temperature nitrogen, the small amount of moisture in the airflow is condensed and sublimated into ice crystals, and the ice crystals are adsorbed by the dehumidification unit 74, so that the moisture in the airflow is removed for the second time; the content of nitrogen in the airflow is increased, so that the content of oxygen in the airflow is relatively reduced, and the effect of inhibiting the breeding of bacteria in the brown sugar is achieved.

Since the content of the first removed moisture is greater than that of the second removed moisture, and the first removed moisture is the moisture adsorbed by the outer surface of the dehumidifying unit 74, and the second removed moisture is the moisture adsorbed by the inner surface of the dehumidifying unit 74; this results in a decrease in the quality of the water removal over time as the moisture content on the exterior surface of the dehumidification unit 74 is greater than the moisture content on the interior surface of the dehumidification unit 74. The dehumidifying unit 74 is slidably connected to the air inlet 72, and the inner and outer surfaces of the dehumidifying unit 74 can be exchanged; namely: after a period of time, the dehumidifying unit 74 slides into the cooling shell 71 from the outside of the cooling shell 71, so that the exchange of the inner surface and the outer surface is realized, the water absorption capacity of the two surfaces is balanced, and the dehumidifying quality is ensured.

Generally speaking, this system carries out shredding to the brown sugar piece through reducing mechanism, and when shredding, the round trip alternating air current that utilizes the rotatory time of smashing of rubbing crusher mechanism to produce takes away the brown sugar powder of processing completion, and the brown sugar granule of unprocessed completion will continue to remain in rubbing crusher mechanism shredding until smashing into the powder. The anti-liquefaction device 4 directly cools the inside of the crushing device through two air flows, so as to prevent the brown sugar powder from liquefying due to overhigh temperature; the storage device 5 can separate and collect brown sugar powder in the airflow under the condition of extremely low influence on the airflow speed; the solidification prevention device prevents the brown sugar powder from being recombined and solidified into the massive brown sugar after absorbing water by removing the water in the air inlet flow; this system can be processed into brown sugar powder with cubic brown sugar, and the circumstances of brown sugar powder solidification and liquefaction can not appear in this system, does not have any cubic or large granular brown sugar that does not smash completely in the brown sugar powder of collecting.
