Description

[0001] The present invention relates to a tray for drying a surface of fresh strawberry,

The present invention relates to a tray for drying potato surface.

In the case of strawberries, there are two methods of distribution after harvest: circulating at room temperature without precooling, circulating at low temperature without precooling, and circulating at low temperature and precooling. It is known that the method of circulating at a low temperature can keep the freshness of the strawberry high and extend the distribution period.

Thus, fruits such as strawberries are rapidly precooled for extended shelf life after harvest.

If the harvested strawberry is quickly pre-cooled, it is sterilized and the freshness and preservability of the product can be maintained excellent. Generally, fruits and vegetables such as vegetables and fruits harvested at the right time are rapidly cooled to a temperature of 0 ° C to 10 ° C, and the surface of the fruits is dried to stop the growth of their own cells. Thus, consumption of nutrients is prevented, So that it is possible to maintain and preserve freshness for a long time in the distribution process.

Such a precooling device is disclosed in Korean Patent Publication No. 10-2003-0022609.

The above-described pre-cooling device has a plurality of through-holes formed in one side wall of a cylindrical differential pressure generating part, blowing cold air discharged from the cooling unit into a differential pressure generating part by a fan, discharging the cold air through the plurality of through holes, And the pre-cooling treatment of the raw strawberry.

However, when the strawberry is pre-cooled through the above-described pre-cooling apparatus, the strawberry portion contacting the differential pressure generating portion is not brought into contact with the cold air introduced into the differential pressure generating portion, so that the entire surface of the strawberry can not be uniformly precooled, Thereby causing a problem that the mold is parasitized through the non-dried part and the quality is lowered.

The present invention has a problem in solving the above-mentioned problems.

The present invention can solve the above-mentioned problems by providing a tray capable of minimizing the contact area with the loaded juice while having a ventilation structure in upper, lower, left, and right sides.

According to the present invention, when the raw strawberry is pre-cooled through the pre-cooling device, the strawberry portion contacting the tray is minimized, and the cool air introduced into the tray and the entire surface of the raw strawberry are evenly contacted, The entire surface is evenly dried to prevent parasitism of the mold, thereby lowering the deterioration of quality over time and increasing the shelf life.
