自体不向きである等の難点があつた。 In addition, in the case of hot water type retort equipment, there is a drawback that the processed material stored in the tray becomes unstable due to the influence of the buoyancy of the hot water, and it is complicated to install a presser lid on the tray. A new configuration was required. This effect is particularly severe in the case of air-containing containers, and in the case of pharmaceutical infusion soft packs, etc., there are disadvantages such as the fact that they are not suitable for immersion in hot water.

一温度化でき効率の良い処理ができる。Function: In the present invention, a spray section that spouts hot water or cooling water is provided on both sides of each tier of trays stacked in multiple tiers, and this spray section is sprayed in response to each tier of trays by the vertical movement of the header pipe. The spray nozzle was positioned so that each stage was evenly sprayed. Therefore, the objects to be processed stored in the trays are sprayed with hot water or cooling water in close proximity to each other at each stage, and as the header pipe moves up and down, each stage of the tray is evenly sprayed. It can be processed quickly and at a uniform temperature. No matter how many trays there are, there is no temperature difference in the vertical direction due to the vertically extending header pipe and the vertical movement of this header pipe, so uniform processing is possible, and unlike processing in hot water, the processing material Since there is no floating water, a stable state is maintained, and the hot water or cooling water is ejected in the form of a fine droplet mist, the temperature around the area where it is sprayed is uniform, allowing for efficient treatment.

が行なわれる。 The trays 2 are stacked in a plurality of stages, and a spray section 4 is provided toward the tray surface of each stage, so hot water or cooling water passes through the circulation path 5 and is sprayed from the spray section 4 into fine water droplet-like mist. Scattered horizontally in a fan shape. Furthermore, since the spray is evenly distributed by the vertical movement of the header pipe, the objects 3 to be treated can be uniformly treated regardless of how the trays are stacked.
加熱工程が終了すると、レトルト外に設けてい

水９を供給し、噴霧に使用していたレトルト内の
熱水を徐冷する。 When the heating process is completed, cooling water 9 is supplied in place of the hot water 8 as a heat source for the heat exchanger 7 provided outside the retort, and the hot water inside the retort used for spraying is gradually cooled.

接供給する。 Eventually, the circulating hot water is indirectly cooled by a heat exchanger, and water that is about 3 to 5 degrees Celsius higher than the cooling water is sprayed into the retort. Additionally, if necessary, the temperature of the circulating water is lowered to a certain extent to a temperature range where there is no need to worry about deformation of the air-containing container (this temperature varies depending on the product being processed, but for example, the temperature difference is around 20°C). At this point, supply cooling water directly to the spray section.
冷却水を循環路からスプレー部に直接供給する
場合はレトルト内の液位が上がらないようポンプ
６の吐出側のバイパス１０からレトルト内の水を
排出するようにした。 When cooling water is directly supplied to the spray section from the circulation path, the water in the retort is discharged from a bypass 10 on the discharge side of the pump 6 to prevent the liquid level in the retort from rising.

る。Effects of the invention In this invention, hot water or cooling water is ejected in the form of a spray from a vertically arranged header pipe, and by the vertical movement of the header pipe, it is evenly distributed horizontally in a fan-shape according to each stage of the tray. Since it is spread, uniform heating treatment is performed at each stage. Hot water has no latent heat of vaporization compared to steam, and is sprayed from the spray section in the form of a fan-shaped mist of fine water droplets, allowing for gentle heat treatment of the object to be treated.

態で処理が行なわれる等の効果がある。 In this invention, even if there are multiple trays as described above, the vertical movement of the header pipe allows the treatment to be carried out without any unevenness in the processing temperature on the plane of the tray according to each tray, resulting in high efficiency and water capacity. I now need less. In addition, since heating is performed using a heat exchanger outside the retort, a hot water tank can be omitted compared to conventional two-tank retort equipment, and furthermore, there is no heat treatment in hot water. Therefore, there are effects such as the processing being carried out in a stable state without the objects to be processed floating.

It is also possible to cool down gradually or in stages.
