A feed sample freezer for accurate identification.

In general, as a standard for group meals provided in facilities used by multiple people such as schools and hospitals, laws and regulations are provided to prevent meal accidents caused by group meals and to identify causes when an accident occurs. According to this, the food provided in the group food service is to store a serving sample for 72 hours at a temperature of 5 ° C each time, so that the pathogen detected in the patient's specimen and the stored food sample at the time of the feeding accident occur. By comparing the detected pathogens with each other to determine whether they are consistent, the cause of the feeding accident is identified, and post-precautions can be taken or responsible material can be determined.

However, in most of the catering establishments, feeding samples are stored in a general refrigerator. In other words, the feed sample refrigerator that can store the feed sample to meet the conditions prescribed by the relevant laws and regulations is not provided separately, the situation is very poor management.

When the food sample is stored in the refrigerator together with the general food, the refrigerator is frequently opened and closed, so it is very difficult to store the sample in accordance with the legislative conditions, and it is difficult to accurately manage the import and export of the food sample. For example, when the feed sample is temporarily taken out of the refrigerator to store food in the refrigerator compartment and then stored in the refrigerator compartment again, it is difficult to maintain a normal state of the feed sample. In addition, storage in a common refrigerating chamber is difficult to ensure that the storage temperature is kept in compliance with the legislation, and it is difficult to ensure that the storage period is kept in compliance with the legislation. In addition, it is possible to keep the food mixed with various foods, such as the food is damaged or mixed. This series of problems is sufficient to raise questions such as whether feeding samples can be used to determine the exact cause of a feeding accident.

On the other hand, after storing the feed sample for about 3 days at a temperature of 5 ℃, natural decay of the feed sample is started separately from bacteria and the like that caused the feeding accident, it is difficult to identify the actual cause. However, group meals are becoming more and more large, and patients tend to be spread over a large area, and it is not recognized as a meal accident at the beginning of the onset, but it is estimated to be a meal accident after three days, and the investigation is often started. Given this, there is a need to further prolong and strengthen the management of food samples.

The display panel 50 may be formed in a single structure so that the information of the feeding samples for the entire tray 120 may be displayed at once, and the plurality of displays may be displayed separately for the information of the feeding samples of each tray 120. It could be a panel and installed in each sub door.

The cold air supply unit 10 includes an expansion valve for diffusing and evaporating condensed liquefied refrigerant, an evaporator for generating cold air through a heat exchange process by a low temperature / low pressure refrigerant discharged from the expansion valve, and an evaporator. Compressor for sucking the evaporated low-temperature and low-pressure gas refrigerant to increase the pressure to the saturation pressure corresponding to the condensation temperature, and a condenser (condensor) for heat-condensing the high-temperature high-pressure gas refrigerant discharged from the compressor by condensing .

The cold air supply unit 10 is configured on a space provided at the bottom and the rear of the main body 110 to generate cold air by the above-described conventional refrigeration cycle. At this time, the cold air supply unit 10 may store the feed sample at a temperature condition that can be stored for a long period of time without bacteria occurring on its own in a state in which a feed sample of one week is put in, for example, 7 days or less at 18 ° C. (18 ° C.) or less. It is desirable to be designed to have a cooling capacity that can.

The sensing unit 20 is composed of various sensors such as an optical sensor or a proximity sensor that can detect whether a feed sample is taken in or taken out, or a weight sensor that detects a load of an imported feed sample. It may be installed on the inner surface of the main body, the upper surface or the bottom surface of each tray.

The memory 30 is configured such that the stored information is accessible only by the controller 40, and further includes a locking device (not shown) for preventing physically leaving the memory 30.

The control unit 40 stores the detection date and time in the memory 30 for each tray 120 when one of the import and export of the feed sample is detected from each sensing unit 20, and carries in each of the plurality of trays 120. And store the discharge history so as to control driving of the cold air supply unit 10 according to a signal applied from the temperature sensing unit 60 so that the storage temperature of the feed sample is maintained at a predetermined temperature.

On the other hand, the feed sample freezer is configured with an input unit 70 formed of a setting key or a touch pad for inputting information such as setting of a storage temperature or a password of a user.

Hereinafter, the operation of the feed sample freezer according to an embodiment of the present invention.

When the feed sample is to be stored in the feed sample freezer configured as described above, first, the internal temperature of the freezer compartment in which the feed sample is stored is set to a predetermined temperature. The internal temperature is intended to prevent natural decay of the feed sample. It should be decided in response to the period. It will be appreciated that samples stored when the freezing period and temperature do not correspond will lose value as a reference sample to determine the cause of the feeding accident. This example assumes 7 days as the storage period, and the internal temperature is set to be below 18 ° C. so that the feed sample can be stably stored during this period.

In this state, when the food provided to the subject of the meal is cooked, one serving is prepared each time and is put into the internal space of the freezer. In this case, the door 130 may be opened to expose the entire internal space, and then input may be performed. However, when the door 130 is opened, the cold temperature is released as a whole, and the internal temperature is increased, so that the storage temperature of the feed sample is rapidly increased. Change, the energy is wasted by causing unnecessary driving of the cold air supply unit 10 according to the cold air loss. Therefore, as shown in FIG. 3B, when only the tray 120 side sub door 140 corresponding to the input point is opened and the feed sample is pushed in, the problem caused by the discharge of cold air can be reduced.

When the feed sample is brought in, the sensing unit 20 detects this and applies a detection signal to the control unit 40. The control unit 40 controls the memory 30 to correspond to the serial number of the loaded tray and the import date and time according to the detection signal. ) And on the display panel 50 to display the import information of the feed sample.

On the contrary, when the feed sample carried in the tray 120 is taken out for inspection or inspection of the feed sample, the controller 40 stores the export information in the memory 30 and displays the same by the same control operation as when the feed is taken. It is displayed on the panel 50.

As a result, the import and export history of the feed sample is stored and maintained in the memory 30 by the above-described control operation, so that management problems caused by user's error or carelessness and intentional operation by others can be prevented. In this case, the cause can be more accurately identified in the case of a meal accident.

In particular, the feed sample freezer according to the present embodiment, the locking device is provided in the memory 30 in which the information of the feed sample is stored to block the access of others, the information of the feed sample stored in the memory 30 is Since only the legitimate user can be accessed by the control unit 40, it is possible to prevent damage, tampering, etc. by others, thereby improving the reliability of the inspection when identifying the cause of the feeding accident.

The feed sample freezer according to the present invention does not provide an input means by which a user can access the memory 30. Like the black box in the aviation system, the controller 40 performs only an operation of adding information on a new carry-in / out date and time, so that the memory 30 does not delete or change the carry-in / out time for the tray 120. To keep on. Therefore, the possibility of artificial manipulation of the stored information in the memory 30 is excluded, and when a search is required, the lock device for the memory 30 may be released and separated from the freezer to confirm.

In addition, since the internal space of the freezer in which the feed sample is stored is partitioned by a plurality of trays 120, even if a large number of feed samples are brought in, they are conveniently stored more systematically without being confused or mixed with each other. Management is carried out effectively.

For example, when seven trays are prepared on a daily basis, the reference period can be assumed to be seven days. On the other hand, if the five-day week is taken under the same conditions, the reference period can be extended to nine days. For each tray, the food samples are replaced one day per normal storage, so trays that reach the baseline are cycled one day per day. The light emitting lamp 80 corresponding to the tray storing the feeding sample is turned on for the reference period, and when the feeding sample is taken out, the light emitting lamp 80 is turned off.

In this way, the light emitting lamp 80 and the storage space side of each tray 120 in the open state of the door 130, so that the operator can easily recognize the state that the storage period has reached a predetermined reference period It may be installed on the edge of the main body 110 corresponding to the same horizontal line. That is, the door 130 may be installed at the edge of the main body 110 corresponding to the open side edge of the door 130, but may be installed in a manner of being embedded so as not to cause interference or damage when the door 130 is opened or closed.

In addition, the light emitting lamp 80 may be configured at a position adjacent to the display panel 50 so as to easily recognize whether the storage period is reached from the outside, or to emit a green LED when the reference period is not reached. When the period is reached, it will be possible to distinguish the red LED by emitting light. In addition, if the heating wire as described above is provided in the guide rail, the control unit 40 operates the heating wire of the corresponding guide rail while turning on the light emitting lamp 80 when the storage period reaches the reference period.
