Multi-temperature-region ice-temperature fresh keeping storehouse and fresh keeping method for bergamot pears

Abstract

The invention discloses a multi-temperature-region ice-temperature fresh keeping storehouse and a fresh keeping method for bergamot pears. The multi-temperature-region ice-temperature fresh keeping storehouse for the bergamot pears comprises a precooling region, a feeding and discharging channel, a cooling region, an ice temperature detecting device, a grading device, a conveyer belt control device, an automatic storing device, and a temperature rise and fall buffering channel, wherein the cooling region comprises four freezers, and the four freezers are respectively a first freezer of which the storing temperature is 0 DEG C, a second freezer of which the storing temperature is minus 1 DEG C, a third freezer of which the storing temperature is minus 2 DEG C, and a fourth freezer of which the storing temperature is minus 3 DEG C; and the four freezers are connected level by level according to a temperature lapse rule. According to the multi-temperature-region ice-temperature fresh keeping storehouse disclosed by the invention, multi-temperature-region graded storage of the bergamot pears is realized according to the value of ice temperature. Compared with conventional static ice temperature storage, the multi-temperature-region ice-temperature fresh keeping storehouse and the fresh keeping method for the bergamot pears disclosed by the invention have the advantages that the storing partitions of the bergamot pears can be dynamically adjusted according to the changes of the ice point temperature of the bergamot pears, so that the situation that the bergamot pears are always stored under the condition of being close to the ice point temperature can be guaranteed, the bergamot pear fruits are prevented from freeze injury, and the shelf life of the bergamot pears is prolonged.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable fresh-keeping warehouses and fruit and vegetable ice-temperature fresh-keeping, in particular to an ice-temperature fresh-keeping warehouse and a fresh-keeping method for fragrant pears in a multi-temperature area. Background technique [0002] Korla fragrant pears have thin skin, juicy, sweet, crispy, nutritious, and good quality, but they are not resistant to storage. After about 15 days of storage at room temperature, the pulp begins to soften, and the skin loses water and shrinks, thus reducing the commodity value. Therefore, how to extend the fresh-keeping period of fragrant pear more effectively and maintain its original quality and flavor is of great significance. [0003] The existing fresh-keeping methods for fragrant pears mainly include traditional low-temperature refrigeration and modified atmosphere preservation, as well as the ice-temperature storage technology developed ...

AI Technical Summary

Problems solved by technology

Although the invention patent can provide a multi-storey cold storage, and can also perform refrigeration according to refrigeration needs, the invention does not involve ice temperature storage technology, and the storage temperature is not designed according to the law of gradient descent, which may easily lead to chilling injury of fruits and vegetables, occurrence of freezing injury and The quality has declined, and the purpose of freshness preservation has not been achieved
