Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for loading and unloading processed materials in a high-pressure tank.

As a device for continuously and efficiently heating and sterilizing food and other foods in a high-pressure tank, the high-pressure tank is equipped with an access mechanism protruding from the tank, which is divided into multiple sections by integral or separate closure pieces with a processing container supported by a conveyor chain. It is known in Japanese Patent Publication No. 53-3696 to move the processing container in and out, but in this method, the pressure inside the high-pressure tank acts directly on the processing container and the closure piece, which increases the driving force load and increases the processing speed. container,
The closing piece must also be made sturdy to withstand the strength of the closing piece, and therefore has drawbacks such as poor thermal efficiency.

The present invention has been developed to improve these deficiencies by connecting the end of a high-pressure tank containing liquid and the area below the liquid level of a water storage tank through a conveying passage formed by arranging a plurality of cylindrical casings in parallel. In the cylindrical casing, there is provided a rotary closing body having two or more blades that are in sliding contact with the inner wall surface of the casing so as to rotate in the same direction. The conveying passage is always closed by one of the blades of the rotary closing body by maintaining a phase difference between the blades (number of blades), and a high-pressure tank and a high-pressure tank are provided on both inner walls of the conveying passage to support a processing container. A pair of conveyor chains that circulate around the water storage tank are arranged so that the speed of movement is the same as the rotational speed of the blade, and each processing container is arranged at minimum equal intervals so as not to come into contact with the blade, and The gist of the system is that it is equipped with a device that returns the liquid to the high-pressure tank. An embodiment of the present invention will be described with reference to the drawings. One end of a high-pressure tank 1 containing liquid and a water storage tank 2 with an open top are connected to a plurality of cylindrical casings 3, 3 under the liquid surface.
A rotary closing body 6 is connected to the conveying passage 4 formed by arranging them in parallel, and each cylindrical casing 3 has two or more equally spaced blades 5 disposed in sliding contact with the inner wall surface thereof. , 6 are provided to rotate in the same direction (clockwise in the drawing), and in particular, the blades 5 of the adjacent rotary closures 6, 6 are rotated in the same direction (clockwise in the drawing). The blades are formed so as to maintain a phase difference of degrees (n is the number of blades).

That is, when the rotary closure body 6 has two blades 5, the angle is 90 degrees;
A phase difference of 60 degrees is maintained in the case of three blades, and 45 degrees in the case of four blades as shown in the drawing, and the blade 5 of one of the adjacent rotary closing bodies 6 closes off the conveyance path 4. In this case, the blade 5 of the other rotary closing body 6 is formed so as to communicate with the conveying passage 4. Further, upper grooves 7, 7 and lower grooves 8, 8 are provided at the upper and lower portions of the inner wall surface on both sides of the conveyance passage 4, respectively, to face each other. It enters the high-pressure tank 1 through the chain wheel 10 of the water storage tank 2, passes through the upper grooves 7, 7, circulates inside the high-pressure tank 1, passes through the lower grooves 8, 8, and enters the chain wheel 1' of the water storage tank 2. Then, the pair of conveyor chains 9 are stretched in an endless manner so as to come out above the water storage tank 2 again.
, 9, a porous processing container 11 for storing the processed material is supported, and furthermore, the bottom of the water storage tank 2 and the high pressure tank 1 are supported.
A vibrator 13 having a pump 12 is connected to the vibrator 13 so that the liquid in the water storage tank 2 can be returned to the high-pressure tank 1.

Since the embodiment of the present invention is constructed as described above, the processing container 11 containing the processed material is transferred from the water storage tank 2 by the pair of conveyance chains 9, 9, and at the same time, the rotary closure bodies 6, 6 are rotated clockwise. When moving, the adjacent rotating obturators 6, 6
Due to the phase difference between the blades 5, the conveying path 4 is closed to the rotary blockers 6, 6. The blades 5 of the rotary closing body 6 on the side of the water storage tank 2 in FIG. In the upper part, the processing container 11 is transferred between the rotary closure bodies 6 and 6 with this rotation, and the blade 5 of the rotation closure body 6 on the high pressure tank 1 side is rotated from the open position to the closed position. , 5 is fed into the high pressure tank 1.

On the other hand, in the lower part of the conveyance passage 4, the rotary blocker 6,
Contrary to the above, the processing container 1 is heated and sterilized in the high-pressure tank 1 by the phase difference rotation of 6 and the transfer action of the conveyor chains 9, 9.
1 is sequentially sent out from the high-pressure tank 1 to the water storage tank 2 through the rotary closure bodies 6, 6.

However, in this case, the liquid in the liquid 1 leaks into the water storage tank 1 from the opening/closing of the conveying passage 4 by the rotary blockers 6, 6 and the grooves 7, 7, 8, 8, but this leaked liquid is removed by the pump 12. is returned to the high-pressure tank 1 again.

Incidentally, as the number of blades 5 of the rotary closing body 6 in the present invention increases, the interval between the processing vessels 11 becomes narrower and the processing efficiency is improved. The number of blades is preferably 2 to 6, and both side edges and outer edges of each blade 5 are urged outward with springs so as to slide into contact with the cylindrical casing 3 as airtightly as possible. It is preferable to fit a wear-resistant sliding contact plate made of Teflon, Rulon, or the like.

Further, the number of cylindrical casings 3 in the conveyance passage 4 is not limited to two as in the embodiment, but three or more can be arranged in parallel, and furthermore, the axial distance, that is, the interval between the respective cylindrical casings 3, 3 is also the same as in the embodiment. In this way, it is possible to accommodate not only one processing container 11 but also a plurality of processing containers 11 between the rotary closing bodies 6, 6.

In the present invention, a conveyance passage connecting a high-pressure tank and a water storage tank below the liquid level is formed by arranging a plurality of cylindrical casings in parallel, and a blade rotates within each cylindrical casing while maintaining a phase difference. A rotating blocker is provided to prevent direct communication between the high pressure tank and the water storage tank by opening the transfer passage when the blades of one of the rotating blockers closes the conveyance passage. Since the processing container is carried in or out while blocking the flow of liquid from the high-pressure tank, the high-pressure liquid in the high-pressure tank directly communicates with normal-pressure water and the process is carried out while preventing its outflow as much as possible. Of course, it is possible to heat and sterilize objects by continuously carrying them into and out of the high-pressure tank, and especially because the pressure inside the high-pressure tank does not directly and completely affect the processing container and attachments of the transport means, unlike in conventional methods. It has an excellent feature that it requires very little conveyance power, and there is no need to make the strength of the conveyance chain and the processing container itself unduly strong, and therefore, a decrease in thermal efficiency can be prevented.
