Description

Rapid precooler for fruits and vegetables {PRECOOLER FOR QUICK COOLING OF GREEN STUFF}

The present invention relates to a rapid pre-cooling device for fruits and vegetables, and more particularly to a pre-cooling device for fruits and vegetables for rapid cooling treatment of fruits and vegetables such as vegetables and fruits in a short time.

Generally, vegetables and fruits harvested in a timely manner are rapidly cooled to a temperature of 0 ℃ -10 ℃ to stop the growth of their own cells to prevent the consumption of nutrients and suppress the growth of various bacteria, thus maintaining freshness for a long time in the distribution process. The fruits and vegetables are being cooled for preservation.

Conventionally, as a facility for cooling fruits and vegetables at low temperature, there is a low temperature refrigerator equipped with a cooling cooler. These cold refrigerators carry fruits and vegetables in their internal cooling chambers and store them for a long time. The cold air circulates the internal cooling chambers to cool the fruits and vegetables, but the cold winds circulate spaces that are less resistant than the fruits and vegetables. The effective low temperature treatment is difficult and takes a long time for the required degree of low temperature treatment.

In the present invention, in view of the above-mentioned point in the prior art, the fruits and vegetables are loaded on the pallet in a state in which the fruits and vegetables are transported in a box and cold air is circulated from both sides to the center by using a trolley and vice versa from the center to both sides. It is to be able to quickly cool the fruits and vegetables by bringing in and out of the container equipped with a cooling chamber.

To this end, according to the present invention, a cooling cooler operated by a cooling unit outside the container is disposed on an upper side of a container in which an upper side wall, a lower side wall, and both side walls and a rear wall are assembled with a heat insulating panel and an opening / closing door is installed on the front side. According to the present invention, the inner bulkhead is placed adjacent to the rear wall to form a front chamber between the rear wall and a side partition wall having a plurality of holes formed adjacent to both side walls. A side chamber is formed between the two side walls to communicate with the front chamber, and these inner and side partition walls form an internal cooling chamber together with the upper side wall and the lower side wall, and a passage communicating with the front chamber is formed in the lower center of the upper side wall. The channel is installed and the lower part of the channel is arranged at a lower distance from the lower side wall at the center of the lower part of the channel. It extends in communication with the vertical channel formed with a number of holes, and divides the internal cooling chamber in the transverse direction, and is formed by installing a fan fan hood between the front chamber and the channel communicating with it on the front side.

Cooling coolers 26 and 28 operated by the cooling unit 24 outside the container are disposed in the chamber, and the inner partition wall 30 is placed adjacent to the rear wall 18 to form a rear wall 18. Between the side walls 14 and 16, the front chamber 32 is formed therebetween, and the side partition walls 36 and 38 in which a plurality of through holes 34 are formed close to both side walls 14 and 16 are inserted. Side chambers 40 and 42 are formed in communication with the front chamber 32, and these inner partition walls 30 and the side partition walls 36 and 38, together with the upper side wall 10 and the lower side wall 12, form an internal cooling chamber. A channel 48 is formed in the lower center of the upper side wall 10 to form a passage 46 communicating with the front chamber 32, and a lower end 50 is formed in the lower center of the channel 48. ) Is a constant distance from the lower side wall 12 52 and disposed on both sides of the diaphragm 54 and 56 to extend the vertical channel 60 in which a plurality of through holes 58 are communicated so as to bilaterally divide the internal cooling chamber 44 in a transverse direction. 26 and 28 are disposed above the internal cooling chamber 44 bisected near the inner partition 30, and are blown between the front chamber 32 and the channel 48 in communication with the front chamber 32 at the front chamber 32 side. The ventilation hood 64 in which the fan 62 is installed is installed, and the lower rail 12 is constructed by installing the trolley rail 66. In the drawings, reference numeral 68 is a fruit and vegetable conveying box, 70 is a pallet, and 72 is a bogie.

The present invention is such that the cooling coolers 26 and 28 installed on the upper part of the internal cooling chamber 44 are operated by the cooling unit 24 to cool the internal cooling chamber 44. The fruits and vegetables to be cooled are loaded in two rows, leaving the center space on the pallet 70 as it is inserted into the fruit and vegetable transport box 68, and the pallet 70 is loaded on the trolley 72. Thus, the fruit and vegetable conveying box 68 loaded on the trolley 72 is stacked in two rows on both sides with a space in the center, and the lower end 50 of the central vertical channel 60 which bisects the internal cooling chamber 44. Is spaced at a constant distance 52 from the lower side wall 12, which forms the bottom surface of the internal cooling chamber 44, so that the center portion of the trolley 72 and the pallet 70 is formed at the lower end 50 of the vertical channel 60. The fruit and vegetable transport box 68 may be carried into the internal cooling chamber 44 divided into two sides of the vertical channel 60 while passing through the lower side. When the fruits and vegetables carrying box 68 is brought into the internal cooling chamber 44, the door 20 is closed, the cooling unit 24 is operated, and the blowing fan 62 in the blowing hood 64 is operated. When the blower fan 62 is operated to circulate the cooled air, that is, the cold air in the direction as shown by arrow C in FIG. 2, the front chamber 32 formed between the inner partition wall 30 and the rear wall 18 The cold air is circulated to the side chambers 40 and 42 on both sides, ie, the side chambers 40 and 42 formed between the side partition walls 36 and 38 and the side walls 14 and 16 to communicate with each other. It is circulated to the internal cooling chamber 44 through the plurality of through holes 34 formed in the (38). Here, the cold air is an open hole (not shown, but a typical green fruit water transport box is typically made of plastic or cardboard, and a plurality of open holes are formed for the purpose of light weight or aeration) After passing through the fruits and vegetables through the circulation to the vertical channel (60) side vertically extending from the top to the center. The vertical channel 60 has a plurality of through holes 58 formed in the diaphragm 54 and 56 on both sides, and the vertical channel 60 has an upper portion through which the passage 46 communicates with the front chamber 32. Is in communication with the channel 48 of the cold air is circulated through the through hole 58 formed in the diaphragm 54, 56 of the vertical channel 60 into the vertical channel 60, the passage formed in the upper channel 48 Continuous circulation is carried out through the 46 to the blowing hood 64 side of the front chamber 32. As such, after circulating the cold air for a predetermined time, the operation of the blower fan 62 is reversed to allow the cold air to circulate in a direction opposite to the circulation direction, thereby further increasing the cooling effect of the fruits and vegetables.

The present invention as described above is that cold air can effectively and quickly cool the fruits and vegetables brought into the internal cooling chamber 44 by forced circulation. This is because the direction of the cold wind can be alternately alternately circulated so that the cold wind is circulated from both sides to the center or from the center to both sides of the internal cooling chamber 44. Cooled fruits and vegetables can be taken out in reverse order.

As such, the present invention loads the fruits and vegetables on the pallet in a state in which the fruits and vegetables are transported in the box, and uses a trolley to carry in and out of the container with a cooling chamber in which cold air is circulated from both sides to the center and circulated from the center to both sides. This has the advantage that it can be cooled quickly.
