JPS58170465A - Apparatus for controlling post-ripening treatment of fruit - Google Patents

Abstract

PURPOSE:To carry out the post-ripening treatment of fruits in high accuracy, with reduced labor, by controlling the post-ripening-controlling apparatus with a microcomputer. CONSTITUTION:The program for the post-ripening treatment and the patterns of specific setting values are stored in the memory 223 of the microcomputer 22. The kind, amount and the color of the fruit are inputted from the keyboard 225, and then the signal for starting the post-ripening treatment is inputted. The preset signals are transmitted from the CPU222 through the output circuit 224 to the temperature and humidity controller 6, the starter 9 of a blower, and the control valve 21 for feeding ethylene gas, according to the stored program, and the above devices are controlled thereby. The signals from the temperature and humidity detector 5 are inputted through the input circuit 221 of the microcomputer and processed according to the discrimination program of the CPU222, and when the signals are judged abnormal, an alarm is sounded.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to control of ripening of citrus fruits and the like.

Conventionally, there has been a device of this type as shown in FIG.

In the figure, ゛(, U) is a ripening processing vehicle, (2) is a citrus fruit, (3) is a warming machine, (4) is a humidifier, +6) is a temperature and humidity tester, (6) is a Temperature/humidity/darkness controller, (7) is the air intake compressor, (8) is the blower, (9) is the blower start control panel, (select ethylene gas cylinder, 01 is the manual valve).

Moreover, FIG. 8 is a diagram showing a control program for temperature, humidity, and ethylene gas concentration involved in the ripening process.

Next, the operation will be explained. Citrus fruits (2) to be ripened are placed in the ripening processing vehicle +1). In the ripening process, it is necessary to maintain temperature, humidity, and ethylene gas concentration as shown in Figure 8. For this purpose, the temperature and humidity are determined by detecting the temperature MPt' inside the door with a temperature/humidity detector (6).
The temperature mtt controller (6) compares the set temperature and humidity and operates the warming machine (3) and humidifier (4) L'C\11
lJ a L, 'C is there. About ethylene gas concentration
C controls the amount of delivery from the ethylene gas cylinder αQ by adjusting the manual valve @. In addition, for ventilation before and during additional heating, adjust the opening of the air intake log pump (7) and
ts) is operated by the blower starting motion plate (9) and controlled by the blower.

In addition, the temperature and humidity, ethylene residue concentration, and additional heat treatment time depend on the variety of fruit, stocking jkt,, i! It must be changed depending on the iT chromaticity.

A conventional fruit reheating treatment control device is configured as follows.
Therefore, it is necessary to calculate the target value and change the settings each time the variety of fruit or the color and darkness of the fish in stock differs, and during processing, the set value must be changed manually and the blower must be stopped at regular intervals. There was a need.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and provides a fruit ripening process control device that can be automatically controlled by applying a microcomputer to calculate and output a target value. It is intended to.

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, ``(11)'' to ``(11)'' indicate the same or equivalent parts as in FIG. 1. (2) is the input circuit (221), central processing unit CPU (222), memo = J (228)
), an output circuit (224), and a keyboard (225).

FIG. 4 is a diagram showing the set value stored in the memory (228) of the microcomputer and shown in FIG. Microcomputer (
The memory (228) of 2) stores the ripening process control program shown in FIG. 8 and the setting 4m (j) pattern shown in FIG. When inputting the variety and degree of coloring using the keyboard (225) and giving a signal to start ripening, the central processing unit (IT) CPU (222) outputs temperature and humidity through the output circuit (224) according to the program. Setting signals are given to the controller (6), the blower start platen (9), and the ethylene gas delivery control valve υ to control each of them.

In addition, the measurement signal of the temperature and humidity detector (5) is sent to the central processing unit f through the input circuit (221) of the microcomputer.
Processed by the judgment program of j (222), abnormality'
If the value is reached, an alarm will be generated.

In the above embodiment, a single ripening processing rate is controlled, but a plurality of processing warehouses may be controlled by one micro combinator. This invention is also applicable to the ripening of other fruits.

As described above, according to the present invention, since the ripening process control value +5 is controlled by a microcomputer, it is possible to save labor and perform highly accurate ripening process.
