In the past, facilities for feeding many people, such as factories and large accommodations, can not be cooked in the same way as ordinary households, so facilities for mass production of rice, storage, semi-cooking, In order to achieve this achievement, we have invested a lot of money and efforts to invent semi-automated catering facilities and actually use them.

On the other hand, in the conventional semi-automated cooking equipment, the process of storing and quantifying rice, which is a preprocessing process of cooking, has been difficult to automate. Such a process has heretofore been working purely on manpower.

In addition, since the storage and weighing of rice, which has been relied solely on manpower in the conventional large-scale cooking apparatus described above, has been stored in the bag during storage of rice, the rice is deteriorated by moisture or lost by rats or other pests Not only was there a problem, but since the weighing operation was simply dependent on the supervision of the operator and the operator, it was not possible to adjust the quantity of rice needed and to supply less or more food, And eating problems frequently occurred.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and it is an object of the present invention to automate the quantitative measurement work of rice, which is a process that has not been automated in mass cooking facilities, thereby preventing waste of rice, Of rice is kept clean and safe so as not to be deteriorated by external moisture without being invaded by rats or insects, thereby saving manpower and time required for mass cooking and providing better quality food service .

In order to achieve the above object, the present invention provides a rice storage tank having a lid for feeding rice and having a storage unit therein, and an inlet and an outlet are formed in the upper portion and the lower portion, respectively, A pressure feeding hose connected between a storage load portion of the rice storage tank and an inlet of the metering tank, and a pressure sensor disposed at a lower portion of the rice storage tank, And a discharging shutter provided on the outlet side of the metering tank. The rice contained in the rice storage tank is supplied to the upper portion of the rice storage tank by the air pressure of the blower, When the rice is pumped to the weighing tank and the rice is pumped up, At the same time is not soon as metering sets of discharge shutter is opened, the amount of rice is one to be supplied to the semi device.

The crank 460 is operated by receiving a signal from a control unit (not shown) to operate the nozzle 440 forward and backward. Two limit switches 470 and 472 provided outside the crank 460 are connected to the crank 460, And the open /

The weighing tank 200 fixed to the upper portion of the rice storage tank 100 has an inlet 200 and an outlet 230 formed at the upper and lower portions thereof and a space portion 250 surrounded by the mesh 240, So that the mesh body 240 is spaced apart from the outer wall 260 of the weighing tank 200 at a predetermined interval and the lower portion of the weighing tank 200 is connected to the storage portion 120 of the rice storage tank 100 It is.

A return pipe 500 is installed between the upper part of the weighing tank 200 and the upper part of the rice storage tank 100 so that compressed air compressed and fed by the rice can be returned to the rice storage tank 100.

The control lever 600 is provided on the side of the lower portion of the space portion 250 so that the volume of the space 250 can be increased or decreased. And a fixing lever 630 capable of adjusting the height of the hook body 620 is attached to the outside of the lower portion of the tube body 610.

A discharging chute 232 is extended outward from the outlet 230 of the weighing tank 200. A discharge shutter 290 is hinged to a middle portion of the discharging chute 232, A bent discharge wire 292 is attached to the inside of the discharge chute 232 so as to fit inside the discharge chute 232 attached to the outlet 230 side so that the discharge chute 232 comes out simultaneously when the discharge chute 290 is opened, ), Which is inserted in a clogged state, can be easily discharged.

A magnet switch 270 is attached to the outside of the weighing tank 200 and a link 280 is connected between the magnet 270 and the discharge shutter 290 to discharge the magnet 270 by the operation of the magnet switch 270. [ And the shutter 290 is opened and closed.

The magnet switch 270 for opening and closing the discharge shutter 290 is operated by a signal applied to the control unit and the control unit is connected to the space portion 210 of the weighing tank 200 in addition to the limit switches 470 and 472 A sensor 700 for detecting the rice overflowing downward is disposed below the weighing tank 200. The sensor 700 is operated by a dropping impact of rice and sends a signal to the control unit to receive the signal The magnet switch 270 connected to the discharge shutter 290 is operated and a motor (not shown) for rotating the crank 460 is driven to advance the nozzle 440.

According to the present invention as described above, a cover 110 of the rice storage tank 100 is opened and a large amount of rice can be stored in the storage unit 120. When the rice is put into the storage unit 120, The rice is scattered on both sides of the guide plates 130 and 132 attached to the middle part of the storage part 120 so that the rice is scattered on both sides so that the rice can be prevented from accumulating in the center of the storage part 120, It does not directly hit the nozzle 440 of the pressure feeding means 400 installed at the lower portion of the ink tank 120, so that breakage can be prevented.

Since the storage unit 120 is completely blocked from the outside, it is possible to prevent the rice from being deteriorated by the moisture of the outside or the proximity of the rats and other pests to the rice so that the rice can be prevented from being damaged or contaminated. You can save it.

In order to supply a predetermined amount of rice while storing a sufficient amount of rice in the storage unit 120, the operator operates the control lever 600 attached to the side lower portion of the weighing tank 200, The volume of the space 250 can be increased or decreased by adjusting the length of the rod 620 to be adjusted up and down so that the rod 620 protrudes into the space 250. In this state, When the switch is operated, the control unit actuates the blower 410 of the pressure transmitting unit 400 to inject air into the nozzle 440. At the same time, the crank 460 rotates and one end is eccentrically fixed to the crank 460 The link 464 pulls the nozzle 440 to move the nozzle 440 backward as shown in FIG.

Since the tip of the nozzle 440 is held in the inlet pipe 450 and then is released to the outside, the high-speed air injected from the nozzle 440 is blown into the inlet pipe 450, The pressure inside the pipe 450 becomes relatively lower than the pressure in the storage part 120 due to the principle of Berunui.

When the pressure of the inflow pipe 450 is lowered, the air in the storage part 120 is quickly introduced into the inflow pipe 450 to supplement the pressure in the inflow pipe 450. At this time, Is sucked into the inflow pipe 450 at the same time.

The rice and air sucked into the inflow pipe 450 flow into the inlet 220 of the weighing tank 200 installed in the upper portion of the rice storage tank 100 by the inflow pipe 450 and are dropped in the space 250 .

The air that has been fed to the space 250 of the weighing tank 200 is discharged through the through holes formed in the mesh 240 forming the space 250 and one end And then returned to the rice storage tank 100 so that the pressure in the rice storage tank 100 can be maintained constant.

When the rice in the storage unit 120 is fed and filled in the space 250 of the weighing tank 200, the rice overflows to the outside of the inlet 220, (120).

When rice is overflowing in the space 250 of the weighing tank 200, when the rice overflows, the sensor 700 installed at the lower part of the weighing tank 200 senses this and signals to the control unit that the rice is full The control unit receives the signal and rotates the crank 460 of the pressure transmission unit 400 to advance the nozzle 440 so that the tip of the nozzle 440 is inserted into the inlet pipe 450 The operation of the blower 410 is stopped to prevent air from being sprayed so that no more rice is supplied.

The degree of rotation of the crank 460 is determined by separating the contacts of the limit switches 470 and 472 while the protrusions 462 formed on the outer side of the crank 460 are in contact with the limit switches 470 and 472 provided outside the crank 460 , So that they stop at the maximum and backward positions respectively.

The control unit operates the magnet switch 270 attached to one side of the weighing tank 200 to pull the link 280 so as to rotate the discharge shutter 290 which has been maintained in the shutoff state, The rice weighed in a predetermined amount in the space 250 of the weighing tank 200 is discharged through the discharge chute 232 to the dry or wet semi-apparatus of the following process which is not shown.

When the discharging shutter 290 is opened, the discharging wire 292 attached to the inside of the discharging shutter 290 is also pulled out, so that the rice accumulated in the discharging chute 232 in the discharging chute 232 is easily discharged. The wire 292 prevents bottlenecks on the side of the discharge chute 232 when the rice is discharged and allows the rice to be discharged smoothly.

When the rice in the weighing tank 200 is completely discharged, the magnet switch 270 is operated again in the opposite direction so that the discharge shutter 290 is in the cutoff state, and the next pressurization of the rice is awaited. To automatically and continuously perform the pressurization, metering and discharging operations of rice in a continuous and quantitative manner.

As described above, in the present invention, a large amount of rice is stored in the storage unit 120 of the rice storage tank 100 and can be cleanly and safely stored. The rice in the storage unit 120 is rapidly And is automatically transferred to the space 250 of the weighing tank 200 through the discharge hose 300 by the air to be sprayed and supplied to the space 250 to be dropped into the rice storage tank again with the rest of the rice, And detects that the rice is filled in the space 250 due to the dropping of rice, blocks the supply of further rice, opens the discharge shutter 290, and then discharges a predetermined amount of rice into the semi-apparatus .

As described above, the present invention is characterized in that a predetermined amount of rice is automatically fed into a weighing tank capable of increasing or decreasing the volume from a rice storage tank capable of keeping a large amount of rice clean and safe at once, The operation of the feeding means is stopped and the discharging shutter is opened to supply the rice to the next processing. According to the present invention, a large amount of rice can be stored safely and cleanly by avoiding moisture, rats and other insects In addition, it is possible to solve the problem of hygiene which is held when the rice is stored in the state of the conventional bag, and it is possible to prevent waste of manpower and to work smoothly because it is not necessary to carry out the task of carrying the bag from time to time. Since rice is automatically fed to the weighing tank by means of pressure feeding, There is no need to attach the sensor to detect the falling rice when the space is filled with rice at the lower part of the weighing tank and to stop the operation of the feeding means and to open the discharging shutter so that the rice is automatically stored And it is possible to solve the problem of the occurrence of errors and the loss of rice, which may occur when carrying and weighing rice by the conventional manpower, and it is also advantageous in that a smooth feeding service can be provided.
