Therefore, it is also very important to reasonably control the operation time of the drying device, and the technicians of the company comprehensively consider the above factors, and find that the operation time of the drying device is limited to be more than 1s, further limited to be between 5s and 25s, further limited to be between 10s and 20s after multiple experiments and researches, so that the drying device has a good comprehensive effect.

In the technical scheme, the t3 is less than or equal to 5s and less than or equal to 15s.

In theory, the longer the scraping brush of the scraping brush device is, the better the scraping brush effect is. However, when the operation time of the scraping and brushing device is too long, time is wasted, so that the self-cleaning period of the material cleaning device is too long, electric energy is wasted, and the use cost of the product is increased; however, too short a time period of operation of the scraping device may result in poor scraping effect, so that part of residues still adhere to the inner wall surface of the cleaning cavity. Therefore, it is very important to reasonably control the operation time of the scraping and brushing device, and the technicians of the company comprehensively consider the above factors, and find that the operation time of the scraping and brushing device is limited to be more than 1s, further limited to be between 2s and 20s, further limited to be between 5s and 15s after multiple experiments and researches, so that the scraping and brushing device has a good comprehensive effect.

Specifically, the scraping driving assembly comprises a scraping motor, a driving gear connected with the scraping motor and a driven gear meshed with the driving gear, wherein the driven gear is connected with the scraping piece, the central axis of the driven gear coincides with the central axis of the cleaning cavity, and the scraping piece is connected to the driven gear and synchronously runs along with the driven gear; wherein in step S104, the scraping driving assembly is started by turning on the scraping motor.

In any of the above technical solutions, all steps included in the self-cleaning control method are repeated, so as to perform multiple cleaning on the cleaning cavity.

In the technical scheme, the repetition times are 2-5 times.

By repeatedly executing the above-mentioned procedures included in the self-cleaning control method, the cleanliness of the cleaning cavity can be remarkably improved, and in theory, the more the number of times of repetition is, the better the cleaning effect is. However, the excessive repetition results in excessive cleaning and waste of time, and waste of electric energy and increases the use cost of the product. Therefore, it is very important to reasonably control the repetition number, and the technicians of the company comprehensively consider the above factors, and find that the repetition number is controlled to be 2-5 times after multiple tests and researches, so that the method has higher cleanliness, is not too long, and is not excessively electricity-consuming.

Of course, the capacity of the insoluble material cleaning device for adhering residues is different, and the quantity of substances such as rice residues, starch and the like remained in different material cleaning processes is also different, so that the repetition number is not limited to the range, and the device can be adjusted according to the needs in the actual production process.

The sewage draining device in step S106 has a sewage pumping amount smaller than that of the water inlet device in step S102 (i.e., step S106 specifically includes starting the sewage draining device to pump out part of the sewage in the cleaning cavity 10), as shown in fig. 6, after step S106, the self-cleaning control method further includes:

step S108, starting an air inlet device and blowing air into the annular space 13;

in step S110, the remaining contaminants in the cleaning chamber 10 are discharged.

As before, the cleaning chamber 10 comprises a main body 11 and a housing 12, the space inside the main body 11 is relatively large for cleaning the material, so that the scraping and brushing device is at least partially positioned inside the main body 11 to scrape the residues attached to the inner wall surface of the main body 11; an annular space 13 is defined between the housing 12 and the body 11, and the annular space 13 is communicated with the inner space of the body 11 through a through hole 111, so that a cavity is formed outside the body 11; the water outlet can be arranged on the body 11 or the outer cover 12 or both the body 11 and the outer cover 12, and as the water outlet is communicated with the cavity, dirt in the body 11 can be pumped out by utilizing the cavity, so that the condition that a sewage discharge pipeline is inserted into the cleaning cavity 10 in the prior art is avoided, the space utilization rate in the body 11 is improved, and the internal structure of the body 11 is simplified; and the annular space 13 can isolate materials such as rice in the body 11 from cleaning sewage, so that the cleaning sewage can be conveniently pumped away, and the situation that the materials such as rice block a water outlet can be avoided.

Further, the material cleaning device further comprises an air inlet device, wherein the air inlet device is communicated with the annular space 13, and can blow air to the annular space 13 after the sewage disposal device extracts a part of dirt in the cleaning cavity 10, so that air flow can pass through the annular space 13 and the through hole 111 to enter the body 11, and impurities remained in the annular space 13 and the through hole 111 can be blown into the body 11, so that the impurities are prevented from blocking the fine structures, and normal use of the through hole 111 and the sewage disposal channel is ensured; and the dredging effect can be ensured by controlling the operation time of the air inlet device; and because the sewage pumping amount of the sewage discharging device is smaller than the water inlet amount of the water inlet device, impurities blown into the body 11 can be dissolved or mixed into the residual cleaning water in the cleaning cavity 10 again, and finally the residual sewage is discharged together, so that the thorough discharge of the sewage is realized, and the fine structure related to sewage is ensured not to be blocked.

In step S108, the operation time of the air inlet device is t1, and t1 is more than or equal to 1S.

Preferably, the ratio of b to a is between 0.2 and 0.8.

More preferably, the ratio of b to a is between 0.3 and 0.7.

When the sewage pumping capacity of the sewage discharging device is too large compared with the water inflow capacity of the water inlet device, too little sewage pumping can be caused, so that too much sewage remains in the later period, the meaning of the sewage discharging device is obviously reduced, and for the embodiment that the residual sewage is discharged through the discharge opening 14, the inner pot is dirty; when the sewage pumping amount of the sewage discharging device is too small compared with the water inflow amount of the water inlet device, residual liquid in the cleaning cavity 10 is too small, so that impurities in the air flow blown into the cleaning cavity 10 cannot be well dissolved or mixed into the residual liquid, the residual sewage in the cleaning cavity 10 cannot be thoroughly discharged, and the cleaning thoroughness is affected. Therefore, it is also very important to reasonably control the ratio between the sewage pumping amount of the sewage discharging device and the water inflow amount of the water inlet device, and the technicians of the company comprehensively consider the various factors, and find that the ratio of b to a is limited to be between 0.1 and 0.9, further limited to be between 0.2 and 0.8 and further limited to be between 0.3 and 0.7 after multiple experiments and researches, so that the comprehensive effect is better.
