Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rapid heat treatment apparatus for fruits and vegetables that performs freezing and cooling treatments for fruits and vegetables, or heating treatments for pretreatment, ripening and deastringency.

[0002]

[Prior art]

 Conventionally, when heat-treating fruits and vegetables, the fruits and vegetables are stored in a container box such as a cardboard box with an air vent, and this container box is placed on a multi-tiered rack in the treatment room, and the treated air supplied from the air conditioner is used. It is designed to act on the fruits and vegetables contained in the container box.

[0003]

[Problems to be solved by the device]

 However, in the conventional fruit and vegetable heat treatment equipment, the entire processing room was air-conditioned by a circulation fan. Generally, in this type of processing equipment, the object to be processed is loaded into the processing chamber with a time difference of half a day unit.Therefore, in the conventional system that air-conditions the entire processing chamber, heat treatment is performed until the processing object fills the processing chamber. However, there is a problem that the processing cycle becomes long. The present invention has been made paying attention to such a point, and an object thereof is to provide a heat treatment apparatus capable of sequentially performing heat treatment as much as it is loaded.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms each processed product storage chamber by forming the processed product placement shelf into a box-type structure with an open transfer path side, and forms each processed product storage chamber. A damper is placed on the back wall located on the side opposite to the loading path, an air conditioner is placed at the rear end of the transfer path, and the process air intake port of this air conditioner is connected to the transfer path to create a rear surface in each processing object storage chamber. It is characterized in that a suction flow is formed from the wall side to the conveyance path side, and the ventilation amount is adjusted for each processed material storage chamber by controlling the opening / closing of the damper.

[0005]

[Action]

 According to the present invention, the processed product placement shelves are formed in a box-shaped structure with the transfer path side open, so that each processed product storage chamber is partitioned and formed, and the rear surface of each processed product storage chamber located on the opposite transfer path side is formed. A damper is placed on the wall, an air conditioner is placed at the far end of the transfer path, and the process air intake port of this air conditioner is connected to the transfer path, so that each processed material storage chamber goes from the rear wall side to the transfer path side. Since the suction flow is formed, it is possible to adjust the ventilation volume for each processing object storage chamber by controlling the opening / closing of the damper. As a result, by controlling the opening / closing of the damper, it is possible to ventilate only the required portion, so that the heat treatment area can be partially formed in the processing chamber.

【Example】

 The drawings show an embodiment of the present invention, FIG. 1 is a vertical sectional front view of a vegetable and fruit heat treatment room, and FIG. 2 is a schematic perspective view thereof. In this vegetable and fruit heat treatment room, a transfer path (2) is formed in the center of the processing room (1), and processing object placing shelves (3) are provided on both sides of the transfer path (2) in the longitudinal direction of the transfer path (2). A differential pressure type air conditioner (4) is arranged at the back end of the transport path (2).

[0007] The processed article placement shelf (3) is divided into compartments by arranging shelves having a plurality of placement sections formed in the longitudinal direction of the transfer path (2) in upper and lower multistages (two stages in the figure). The processed material storage chambers (5) are formed in a structure in which they are arranged in a plurality of stages and a plurality of rows. In each processed material storage chamber (5), the front and rear surfaces and the upper and lower surfaces in the longitudinal direction of the transfer path and the side opposite to the transfer path (rear surface) are closed, and the transfer path (1) side is opened to form a box shape. . Further, a ventilation hole (8) having a damper (7) is opened in the back wall (6) of each treated material storage chamber (5).

The differential pressure type air conditioner (4) is arranged such that its suction port (9) faces the transfer path (2), and the discharge port (10) is located inside the processing chamber (1). It is opened in the outer part of (5). In this case, the upper part of the transfer path (2) and the front opening of the transfer path (2) are closed so that the discharge air of the differential pressure type air conditioner (4) does not short-circuit with the transfer path (5). is there.

The temperature and air flow rate of the air conditioner (4) and the opening / closing degree of the damper are configured to be drive-controlled by a controller (not shown).

In the heat treatment apparatus for fruits and vegetables configured as described above, only the damper (7) on the rear wall (6) of the processing-object storage chamber (5) accommodating the object to be processed is opened, and the object to be processed is not accommodated. The differential pressure type air conditioner (4) is operated with the damper (7) in the treated material storage chamber (5) closed. Then, since the transfer path (2) side becomes a decompressed atmosphere, the processing air flows only from the back side to the transfer path (2) side in the processed object storage chamber (5) in which the processing object is stored. In this case, since the treated air is a suction flow, it becomes an omnidirectional flow and smoothly flows along the surface of the object to be treated, so that the entire object to be treated in the object accommodation chamber (5) is uniformly heat-treated. be able to.

Therefore, it is possible to perform the heat treatment in order from the loaded object by opening and controlling the damper at the loading point each time the object to be processed is loaded. As a result, by adjusting the opening / closing degree of the damper (7) based on the elapsed time after the start of treatment in each treated substance storage chamber (5), the total amount of air flow is not changed in each treated substance storage chamber (5). Since it is possible to secure the required air flow for the air conditioner (4), it is possible to make the air conditioner (4) small. In addition, it is possible to shorten the shipping cycle because the processing is completed in the order of loading.

[0012]

[Effect of device]

 According to the present invention, the processed product placement shelves are formed in a box-shaped structure with the transfer path side open, so that each processed product storage chamber is partitioned and formed, and the rear surface of each processed product storage chamber located on the opposite transfer path side is formed. A damper is placed on the wall, an air conditioner is placed at the far end of the transfer path, and the process air intake port of this air conditioner is connected to the transfer path, so that each processed material storage chamber goes from the rear wall side to the transfer path side. Since the suction flow is formed, it is possible to adjust the ventilation volume for each processing object storage chamber by controlling the opening / closing of the damper. As a result, by controlling the opening / closing of the damper, it is possible to ventilate only the necessary portion, so that the heat treatment area can be partially formed in the processing chamber.

Further, since the treated air acts on the object to be treated by the suction flow, the treated air becomes an omnidirectional flow, and the entire surface of the object to be treated can be uniformly treated, so that the heat treatment efficiency is improved. .
