Problems solved by technology

[0005] In order to prolong the period of pears on the market, pear storage and fresh-keeping technology is very important. At present, most of them are kept fresh in underground ventilated cellars. The storage and fresh-keeping time of this method is short. This traditional storage and preservation method can no longer meet the production needs

Embodiment Construction

[0013] In order to describe the present invention in detail, the following will be further described in conjunction with specific examples,

[0014] Pack the fruit in boxes and put them in a cool place for 1 to 2 days and nights, and put them into storage before 8 o'clock the next day. The fruit boxes are placed in the shape of a product, with a distance of 2 to 3 cm between boxes and a distance between the stack and the top of the wall. 60cm, keep a good working channel, lower the storage temperature to 15°C before the fruit is put into the warehouse, close the door after the fruit is put into the warehouse, start the refrigeration and temperature and humidity instrument switch, control the storage temperature to drop by 1°C every 2 days, after falling to 10°C , drop 1°C every day, keep constant temperature after falling to 0-1°C, keep the relative humidity in the cold storage at 85-90%, when the relative humidity is high, use ventilation to reduce the humidity, when the relat...

Abstract

The invention discloses a method for refrigerating crown pears in a cold store, and relates to the technical field of agricultural production. The method comprises the following steps of: boxing and packing the fruits, filling the pre-cooled fruits in the cold store for storing, cooling the cold store to the temperature of 15 DEG C before the fruits are put into the cold store, closing a store door after the fruits are put into the cold store, starting refrigeration, temperature and humidity instrument switches, controlling the store temperature to drop 1 DEG C every two days, cooling the store for 1 DEG C every day after the temperature is dropped to 10 DEG C, keeping constant temperature after the temperature is dropped to 0-1 DEG C, and keeping the relative humidity in the cold store at 85 to 90 percent. By adopting a cold store fresh-keeping mode in the method, the storage and fresh-keeping time of the crown pears is long; cold damage of the crown pears can be effectively avoided by step-by-step cooling; the operation is simple and convenient; and the refrigerating conditions are easily controlled.

Description

Technical field: [0001] The invention relates to the technical field of agricultural production, in particular to a method for storing and refrigerating Huangguan pears. Background technique: [0002] my country is one of the birthplaces of the genus Pyrus. Most of the pears of the genus Pyrus in Asia originate in eastern Asia. Japan and Korea are also the original origins of Asian pears. [0003] Dangshan pear is a famous product among Chinese fruits. It is well-known at home and abroad for its huge fruit, bright yellow color, thin and juicy skin, multi-core meat and small, sweet and crisp. In 2010, Dangshan County was listed in the Guinness Book of World Records as the number one pear county in China. [0004] Due to the single variety, large quantity and consistent maturity period of Dangshansu pear, it has brought great pressure on the fruit sales market in various places. In order to promote the adjustment of the pear industry structure, since 2000, Chinese and forei...
