JP4387127B2 - Easy-sealed double bag heat treatment method and tray used for this heat treatment - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for heat-treating a double bag used for foods, health foods, medical products and the like with a heat treatment machine such as a retort, and a tray used therefor.
[0002]
The double bag as used in the present invention refers to a bag in which liquid, liquid, powder, liquid, and other two or more contents are separated or stored in a seal part, and easy seal is always a seal part. Two or more kinds of contents are isolated, but it means a sealed state that can be easily opened by fingers during use.
[0003]
[Prior art]
Conventionally, in an easy-seal double bag, no means has been considered for protecting a seal portion that isolates two or more objects to be processed during heat treatment.
[0004]
In the case where a pouch such as food is heat sterilized inside the tray, there is an example in which a protrusion for partitioning the inside of the tray is provided. However, this is limited so that the pouch does not float up or move inadvertently in trays stacked in a plurality of stages, and is different from the example in which the seal portion is protected as in the present invention.
[0005]
Further, there is an example in which a pillow portion is provided at the neck portion of a soft bag made of synthetic resin, and a receiving metal fitting is provided on this pillow portion (Japanese Patent Publication No. 5-55147), but this is different from the configuration of the present invention.
[0006]
[Problems to be solved by the invention]
When an easy-seal double bag is inserted into a high-temperature / high-pressure heat treatment machine such as a retort for sterilization, buoyancy does not work on the double bag, especially in the case of a heating steam injection treatment machine or a hot water spray-type heat treatment machine. In the heat treatment in the state, the strength of the seal part is lowered by heating the double bag that is spread and placed on the tray, and the seal part opens due to the weight of the object to be treated, and two or more kinds of contents are mixed. There was a danger of doing so.
[0007]
An object of the present invention is to provide a heat treatment method in which mixing of two or more kinds of objects to be processed does not occur in a state in which buoyancy does not act on a sealed portion of a double bag that is easily sealed during high temperature heat treatment, and a tray used for this treatment Is to provide.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, in the first invention, a double bag is placed on a tray , inserted into a high-temperature and high-pressure heat treatment machine such as a retort, and when heat treatment is performed without buoyancy acting on the double bag, Heating the double bag as an easy seal that has a partition that partitions the inside of the tray and heat-treats in a state in which the partition supports the seal from below the double bag and can maintain the isolation state of two or more objects to be processed The processing method was used.
[0009]
In the second invention, the double bag according to claim 1, wherein the double bag separates liquid, liquid, powder, liquid, and other two or more objects to be processed by a seal portion, and can be easily opened by fingers during use. A heat treatment method was adopted.
[0010]
In the third invention, as the tray used in the heat treatment method for a double bag according to claim 1 or claim 2, a plurality of partitioning portions crossing the tray are fixed at positions supporting the seal portion of the double bag, or A tray that can be fixed by moving and adjusting as appropriate.
[0011]
[Action]
In the first invention, a partition for partitioning the tray is provided, and the partition supports the seal portion from below the double bag so that two or more kinds of workpieces can be kept in an isolated state. Even if the strength of the part is slightly reduced, the weight of the object to be processed does not directly act on the seal part, so that the seal part does not open.
Accordingly, the easy-sealing double bag can be heated without any concern.
[0012]
In the second invention, the seal part of the double bag uses a liquid, a liquid, a powder, a liquid, and other two or more kinds of contents to be processed, which can be easily opened by fingers during use. .
[0013]
In the third invention, as the tray used in the heat treatment method for a double bag according to the first invention or the second invention, a partition is installed across the tray and fixed on the bottom of the tray, or a double bag seal part By moving to the position of and fixed, the optimum state can be obtained so that the seal portion does not open during the heat treatment.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a heat treatment method for an easy-sealed double bag and a tray used for this heating. The easy-sealed part is a mixture of two or more kinds of liquid and liquid or powder and liquid, etc., which are separated until just before use. The seal part is protected during the sterilization treatment by the heat treatment.
[0015]
【Example】
Sample: 2 liter double bag (synthetic resin pouch)
Contents: Height of dialysis drug 2 liquid partition: 30mm
Heating conditions: 110 ° C, 30 minutes 0.15 MPa Cooling 13 minutes [0016]
When the double bag was heat-treated under the above heating conditions, the treatment was completed without opening the seal part.
[0017]
The shape of the partition can be changed according to the size of the double bag.
[0018]
Details will be described below with reference to the drawings.
[0019]
In FIG. 1, reference numeral 1 denotes a tray, which is stacked in a plurality of stages and carried into a heat treatment machine such as a retort. As shown in FIG. 3, the bottom and side walls have a large number of small holes, for example, in a staggered manner, and correspond to a heating steam spraying type or a hot water spraying type heat treatment machine.
[0020]
Reference numeral 2 denotes a partition, which is arranged in two rows as an inverted U-shape traversing the inside of the tray in the illustrated example, and is fixed to the bottom surface of the tray. Six double bag seals are loaded on these partitions.
[0021]
The partition portion 2 is not limited to the illustrated example, and the fixing position can be appropriately changed depending on the shape of the object to be processed.
[0022]
Reference numeral 3 denotes an object to be treated. For example, two liquids or liquid and powder can be mixed at the time of use like a drug for infusion. Usually, two or more kinds of contents are separated by a seal part 4. Yes. The seal portion 4 can be easily opened by pulling the workpiece so as to be separated by fingers during use. Reference numeral 5 denotes a content entrance / exit.
[0023]
FIG. 2 is a longitudinal sectional view of the tray 1 and shows the state of the partition 2.
[0024]
FIG. 3 illustrates the heating state of the present invention. The double bag 3 is inflated as the contents expand, but the seal part 4 is supported from below by the partition part 2, so that the contents are not opened. This is a state in which mixing of objects does not occur.
[0025]
FIG. 4 shows a conventional heat treatment state, (A) shows a state before heating, and (B) shows a state during heating. It shows that the contents expand during heating and pressure is applied to the bag, and that the weight of the contents is applied to the seal part and there is a high risk of opening the seal part.
[0026]
5 and 6 are reference views showing the side of the tray. Auxiliary ribs 6 are provided and are stacked in a plurality of stages.
[0027]
When the trays are stacked, an interval is maintained such that the bottom of the upper tray does not hit the lower bag.
[0028]
【The invention's effect】
The present invention provides a method of performing a heat treatment in a state where two or more kinds of objects to be treated are not mixed by opening a seal portion of a double bag which is an easy seal at the time of high-temperature and high-pressure heat treatment such as a retort sterilizer and used for this treatment. Was able to provide a tray to do.
