Description

{DEVICE IN USING COLD CONTAINER}

The present invention is a technology applied to a distribution structure in which producers directly transfer fresh fruit and the like to a consumer through a small-scale distribution. It quickly removes moisture on the skin during low-temperature storage of the harvested fruit and improves the quality of low-temperature storage by lowering the temperature The present invention relates to a post-harvest fruit quality control system for preventing surface condensation due to a temperature difference between a storage and an outside air and preventing quality deterioration during distribution through dehumidification.

Blueberries, oats, bokbunja, etc. are soft and long-term preservation is weak, harvest is done at high temperature and high humidity, there is some time difference between harvesting and consumption, and fruits that require low temperature storage for a certain period of time, Is very important.

For example, blueberry is a shrub plant belonging to the genus Ericaceae ( Vaccinium ). It is known that it possesses powerful functions such as antioxidation and visual enhancement, Long-term preservation is weak, and the harvest is made in the period of high temperature and high humidity from July to August. In particular, the fruit isolated from the tree has a temperature rise of 7 ° C over a short period of time due to self-respiration, and if left at 27 ° C, the average temperature of the harvester, the respiration rate increases by almost 20 times, Occurs

In order to prevent this, it is necessary to sufficiently dry the skin surface within 4 hours after harvest and refrigerate at a temperature in the range of 1 to 5 ° C to suppress the respiratory action of the fruit to near dormancy, And the harvesting box requires quality control efforts such as not to accumulate fruit over 10cm for ventilation and heat dissipation.

In this way, the quality management according to the fruit characteristics has achieved the sufficient result by the experience and the trial and error, but the quality management after the storage of the stored products is not carried out, especially the courier which can not use the cold chain In the distribution process of direct producers and consumers, there is a problem of deterioration due to rapid exposure to outside air. That is, there is a distribution process between harvesting and consumption, and since small-scale distribution can not utilize cold chain network, condensation in the epidermis necessarily occurs due to exposure to outside air accompanied by a rapid temperature change during packaging and distribution.

The over-humidity condition due to condensation is inevitably generated when the material is moved to a packing chamber maintaining a temperature of about 20 to 25 ° C in order to carry out small-volume packing in a small-size box and a styrofoam box for packing and distribution at a low temperature storage state of 1 to 5 ° C.

Moisture condensed by condensation keeps on the bottom of the packaging box and keeps the fruit in a wet state so that there is a drastic change in the quality of the primary fruit during arrival at the final consumer, The quality is changed, and the consumer perceives it as a defect of quality, which causes the product to be returned, resulting in a decrease in consumption.

However, if it is packed without dehumidification under proper conditions, the quality deterioration can not be essentially solved considering the distribution period of at least 2 days. There was a problem.

The present invention provides a technical means for preventing condensation due to a temperature difference between a fruit product temperature and a packaging room in the process of subdividing fruit taken from a low temperature storage container and quickly removing moisture, It is also aimed to improve the low temperature storage quality by rapidly removing the moisture from the epidermis and rapidly lowering the temperature even at low temperature storage of the harvested fruit.

To this end, the present invention provides a refrigerator comprising: a low-temperature reservoir having a cold storage chamber and a packaging chamber each having an independent air cooling system having an insulating panel assembly structure, and having an access door to allow access to and exit from the cold storage chamber through a packaging chamber; A pre-cooling dehumidifier having a separate dehumidifying fan, a rack for feeding fruit, and wheels for moving; An inlet and an outlet for connecting the cryogenic storage compartment and the packaging compartment to and from the pre-cooled dehumidifier; A rail installed so as to support and move the pre-cooled dehumidifier to the respective packaging rooms and the cold storage room through the entrance; And an opening / closing door configured to open / close the door when the pre-heating / dehumidifying device is located in either the cold storage room or the packaging room.

Further, the present invention is characterized in that, in constructing the above-described pre-cooling dehumidifier and the opening and closing door, a front door is integrally installed at the front of the pre-cooling dehumidifier to close the door at the packing chamber side, and a rear door The front door and the rear door are attached with wheels for performing the function of braking the pre-cooling dehumidifier. When the pre-dehumidifier is moved on the rails and exposed to the packaging chamber, the rear door closes the door, And the front door is closed when the door is exposed to the cold storage room by moving on the rail.

The present invention relates to a structure having a cold storage chamber and a packaging chamber each having an independent air cooling system, and a pre-cooling and dehumidifying unit that travels on a rail to a cold storage chamber and a packing chamber. The harvested fruit is passed through a packing chamber, In the process, the pre-cooling dehumidifier is used as a bogie for pre-cooling, dehumidification and fruit-conveying of fruits.
