DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehydrating apparatus, for example, used for a dehydrating treatment in a process of producing anko.

[0002]

2. Description of the Related Art In a conventional dehydrating apparatus, an object to be processed such as a cat is accommodated in a cylindrical case, and a ram is extruded by hydraulic pressure to dehydrate the object.

[0003]

However, in such a conventional dewatering apparatus, since the ram is extruded at a constant rate, the object to be processed is constantly pressurized, so that it enters deep into the object to be processed. The resulting moisture is difficult to discharge, and as a result, there is a disadvantage that it is difficult to improve the dehydration rate.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above object, in a dewatering apparatus according to the present invention, a ram is inserted into a cylindrical case so as to be able to advance and retreat, and an object to be processed is accommodated in the cylindrical case. In the dewatering device for intermittently advancing the ram, the intermittent advancing of the ram is performed by pulsation of pressure oil generated by a plunger pump whose rotation of a crankshaft is set to 120 RPM or less. Things.

[0006]

Since the dewatering device according to the present invention is configured as described above, when the ram stops intermittently, water that has entered deep into the object to be processed flows out and is discharged by pushing out the next ram. The pressurized oil for moving the ram forward can be intermittently discharged by the plunger pump.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, D is a dehydrator for bean paste, and 10 is a frame of the dehydrator D. Reference numeral 20 denotes a cylindrical case, which is fixed while being mounted on the frame 10. The cylindrical case 20 is for accommodating the beans M before dehydration. Reference numeral 21 denotes a hopper, which is installed above the cylindrical case 20. The cat M is supplied to the cylindrical case 20 via the hopper 21.

Reference numeral 30 denotes a first cylinder, which is fixed to the frame 10. Reference numeral 31 denotes a ram, which is fitted inside the cylindrical case 20. The ram 31 moves back and forth in the cylindrical case 20 by the piston / cylinder mechanism of the first cylinder 30. 311 is ram 3
Reference numeral 312 denotes a drainage hole formed in the ram 31.

Reference numeral 40 denotes a second cylinder, which is fixed to the frame 10. Reference numeral 41 denotes a receiving lid, which is installed at the right end opening of the cylindrical case 20. The receiving lid 41 opens and closes the right end opening of the cylindrical case 20 by the piston / cylinder mechanism of the second cylinder 40. Reference numeral 411 denotes a filter cloth provided on the front surface of the receiving lid 41;
2 is a drain hole formed in the receiving lid 41.

Reference numeral 50 denotes an oil tank, which is installed below the cylindrical case 20 in the frame D. Hydraulic oil is stored in the oil tank 50.

Reference numeral 60 denotes a vane pump, which is installed on the upper surface of the oil tank 50. The vane pump 60 is driven by a motor 61 to send pressure oil to the first cylinder 30 and the second cylinder 40.

Reference numeral 70 denotes a plunger pump, which is installed in the oil tank 50. This plunger type pump 70 is driven by a motor 71 and is for intermittently sending pressure oil to the first cylinder 30. The rotation speed thereof is set to 300 RPM or less, particularly 120 RPM or less, and The stroke is made as short as possible to enhance the pulsating effect of pressure oil. In addition, 72 is the rotation center of the motor 71, 73 is the crankshaft, 75 is the connecting rod,
76 is a plunger and 77 is a cylinder.

Next, the operation of the dehydrator D will be described.

In the state shown in the figure, the second cylinder 40 is operated by the pressure oil of the vane pump 60, and the receiving lid 41 is advanced to close the right end opening of the cylindrical case 20.

Thereafter, the first cylinder 30 is actuated by the pressure oil of the vane pump 60, and while the ram 31 is retracted, the chopper M is filled into the cylindrical case 20 from the hopper 21.

Thereafter, the first cylinder 30 is actuated by the pressurized oil of the vane pump 60, and the ram 31 is moved forward to press the bean jam M in the cylindrical case 20.
When the pressure inside the cylindrical case 20 reaches a predetermined pressure by a pressure sensor (not shown), the first cylinder 30 is switched to the intermittent pulsating pressure oil of the plunger pump 70, and the ram 31 is intermittently advanced. By this, the bean paste M in the cylindrical case 20 is pressed, and the dehydration of the bean paste M is completed. By the way, a water content sensor (not shown) is provided in the cylindrical case 20 to change the rotation speed of the plunger pump 70 via an inverter (not shown) while detecting the water content of the object M, The intermittent interval of the ram 31 can also be controlled. The squeezed water is supplied to the drain holes 311 of the ram 31 and the receiving lid 41, respectively.
Drained from 411.

After that, the second cylinder 40 is operated by the pressure oil of the vane pump 60, the receiving lid 41 is moved backward, and the right end opening of the cylindrical case 20 is opened.

Thereafter, the first cylinder 30 is actuated by the pressurized oil of the vane pump 60, and the ram 31 is advanced to push out the dehydrated bean jam M from the right end opening of the cylindrical case 20, thereby completing the dewatering operation.

[0019]

According to the present invention, there is provided a dehydrating apparatus in which a ram is inserted into a cylindrical case so as to be able to advance and retreat, and the ram is intermittently advanced in a state where an object to be processed is accommodated in the cylindrical case. Since the intermittent advance of the ram is performed by the pulsation of the pressure oil generated by the plunger type pump whose crankshaft is set to 120 RPM or less, the ram may be intermittently stopped when stopped. A plunger-type pump can intermittently discharge pressurized oil to advance the ram so that water that has entered deep into the processed material flows out and can be discharged by pushing the next ram.

Therefore, the use of the dehydrator can improve the dehydration rate of the object to be treated.
