Pre-cooling device in production place of perishable fruit

Abstract

The invention discloses a pre-cooling device in a production place of perishable fruit, which comprises a pre-cooling area [15] for a fruit and vegetable box, and a pre-cooling mechanism of the pre-cooling area. The pre-cooling mechanism comprises an ice-water box [1] and an air cooler for cooling the air by utilizing circularly flowing water in the ice-water box. The air cooler is provided with an air outlet [9] and a return air inlet [10] which are communicated with the pre-cooling area. A filling layer [5] is arranged in the air cooler. The ice-water box [1] is connected with a spray nozzle [4] positioned on the filling layer [5] through a water pump [2] and an outlet pipe [3]. An exhaust fan [6] for enabling the air and the water to flow inversely is arranged on the spray nozzle [4]. The pre-cooling device can timely treat the picked perishable fruit at low temperature in the production place by a proper pre-cooling way to rapidly eliminate the field heat, effectively reduce the respiration intensity, maintain the excellent fruit quality and prolong the preservation period of the fruit. The pre-cooling device is rationally designed and simply and conveniently operated, and has lower input cost and wide application prospect in the aspect of perishable fruit storage and fresh preservation.

Description

technical field [0001] The invention relates to a perishable fruit producing place precooling device, which belongs to the technical field of fresh-keeping of agricultural products. Background technique [0002] Fruits contain a variety of nutrients needed by the human body, but fruit production has strong seasonality, regionality, and the perishability of the fruit itself. For example, the subtropical fruit lychee will brown and rot within 36 hours under normal temperature conditions. It is contradictory to the diversity of consumers' needs for fruits. Therefore, how to effectively store and transport fruits and maintain their original quality is a topic of great concern all over the world. According to statistics, about 20% to 25% of the fruit in our country is rotted and damaged in transit, transportation and storage every year, seriously affecting the commodity value of the fruit and the economic benefits of the fruit farmers.

Problems solved by technology

According to statistics, about 20% to 25% of the fruits in our country are rotted and damaged in transit and storage every year, which seriously affects the commodity value of fruits and the economic benefits of fruit farmers.

At present, there is no such research report on the timely and rapid pre-cooling treatment of post-harvest fruits at the place of production at home and abroad.
