The present invention relates to a waste food treatment apparatus and a waste food drying control method, and more particularly, a waste which can control a drying process to be set in a required weight value range by measuring a change in weight of waste food to be dried in real time. It relates to a food processing apparatus and a waste food drying control method.

Typically, waste foods, such as food waste, have a high moisture content and easily rot, causing great difficulty in landfilling and incineration.

Accordingly, in recent years, various food processing apparatuses capable of controlling dry food waste have been used.

The waste food treatment apparatus includes a dehydration process of removing water from waste food, a process of compressing and pulverizing waste water from which water is dehydrated, a process of drying the waste food by applying heat while stirring the pulverized waste food, and microorganisms. It is a device that can perform a plurality of processes sequentially or selectively, such as the decomposition process using.

The conventional waste food processing apparatus includes sensing means capable of sensing temperature, humidity, and weight, and controls the operation of the heater, the intake fan, the stirring vane, and the exhaust fan using the sensing means.

When included in the control unit 320 to immediately stop the application of the operation signal to the drying unit 200.

Here, the weight sensing unit is preferably composed of one or a plurality of weight detectors 310. Of course, it may also consist of a single weight sensor.

The weight detector 310 may be configured of any one of a piezoelectric element, a strain gauge, and a load cell.

Referring to FIG. 1, the weight detectors 310 are disposed at a plurality of positions spaced apart at regular intervals from an inner bottom surface of the storage unit 100.

Therefore, when the weight sensing unit is composed of a plurality of weight sensors 310 as shown in FIGS. 1 and 3, the weight values measured in each of the first to n th weight sensors 310 ( W) is transmitted to the control unit 320, the control unit 320 calculates an average weight value for the plurality of measured weight values (W), the calculated average weight value range of the reference weight value It can be determined whether or not it is included in (ΔW).

In addition, the controller 320 may immediately stop the operation of the drying unit 200 when the measured weight value W is not included in a predetermined range ΔW for a predetermined time.

Meanwhile, referring to FIG. 2, the weight sensing unit may further include a settle plate 150.

The settle plate 150 is disposed near the bottom of the inner space of the storage unit 100, and the waste food 10 is placed on the upper surface thereof.

In addition, a plurality of elastic members, such as elastic springs, may be used to guide the return operation of the flowable settle plate 150 to its original position between the settling plate 150 and the bottom of the storage portion 100 ( 170 may be installed.

Next, examples of the waste food drying control method using the waste food treatment apparatus of the present invention having the above configuration will be described.

1 to 4, a predetermined amount of waste food 10 may be introduced into the internal space of the storage unit 100 (S100). Therefore, a predetermined amount of waste food is stored in the internal space of the storage unit 100.

Subsequently, the controller 320 operates the drying unit 200 (S200). That is, the controller 320 operates the blower fan 210, the exhaust fan 220, and the heating heater 230. Here, the air volume of the blowing fan 210 and the exhaust fan 220 may be preset in the control unit 320, and the heating temperature of the heating heater 230 may be preset.

Thus, the heating heater 230 heats the outside air to a predetermined temperature, the heated outside air is introduced into the storage unit 100 by the operation of the blower fan 210, the heated outside air is stored A certain flow may be formed in the internal space of the part 100, and may be exhausted to the outside of the storage part 100 through the exhaust port 121 by the operation of the exhaust fan 220.

Accordingly, since the waste food 10 containing a certain amount of moisture is exposed to a flow of outside air heated to the predetermined temperature, a predetermined amount of water may be evaporated.

Subsequently, the plurality of weight detectors 310 disposed at the bottom of the inner space of the storage unit 100 determine the weight value of the waste food 10 dried by the operation of the drying unit 200 at the corresponding placement position. Measure continuously (S300).

The weight detectors 310 transmit the measured weight values W to the controller 320 in the form of an electrical signal.

Subsequently, the controller 320 determines whether the weight values W are included in the reference weight value range ΔW (S500).

Here, the controller 320 calculates an average weight value by averaging the received measured weight values W, and whether the calculated average weight value is included in the reference weight value range ΔW. Judge.

In addition, when the calculated average weight value is not included in the reference weight value range ΔW, since the waste food 10 may contain a certain amount of moisture, the control unit 320 may include the drying unit. The 200 is operated continuously.

If the calculated average weight value is included in the range ΔW of the reference weight value, since the moisture included in the waste food 10 may be formed at a required level, the control unit 320 Immediately stops the operation of the drying unit 200 (S600).

That is, the controller 320 stops the operation of the drying unit 200 by stopping the operation signal applied to the blowing fan 210, the exhaust fan 220, and the heating heater 230.

Meanwhile, referring to FIG. 5, as described above, the waste food 10 is introduced into the internal space of the storage 100 in a predetermined amount, the drying unit 200 is operated by the controller 320, and the weight detectors ( After the weight value of the waste food 10 that is added and dried from the 310 is measured and the weight value change is monitored in real time, the controller 320 controls the weight value of the waste food to be dried in a predetermined range for a preset time. If not included in (DELTA) W (S400) it is possible to immediately stop the operation of the drying unit 200 (S600).

For example, when the waste food 10 introduced into the internal space of the storage part 100 is a bone of an animal such as a cow or a pig rather than a food waste containing a certain amount of water, the bone is evaporated by the operation of the drying part. May not react as much as possible.

Therefore, when the waste food 10 is the bone as described above, a change in the weight value W measured from the weight sensors 310 may not occur for a certain time.

Accordingly, the control unit 320 according to the present invention to immediately stop the operation of the drying unit 200 in the above case, the power or energy required to dry the waste food 10, such as bones of animals that are not dry You can also save money.
