Problems solved by technology

The drying of fruits and vegetables is mainly done by conventional hot air drying, which has many disadvantages: 1) The apparent color is not good, and it is prone to undesirable color changes such as yellow, brown or black; 2) The loss of nutrients is serious, easy to oxidize, Loss of vitamins; 3) loss of aromatic substances due to volatilization; 4) high-temperature drying material damages the tissue, seriously affecting the quality and taste

Abstract

The present invention discloses a zero-resource-loss heat pump type fruit and vegetable drying processing system and a processing method. The processing system comprises a shell body, a heat pump condenser, a frame body and a heat pump evaporator, and an interior of the shell body is divided into an air treatment chamber, a main drying chamber and an air return channel in head-to-tail sequential communication by partition plates; the air treatment chamber communicates with the main drying chamber through a main circulating fan set; the heat pump condenser is arranged in the air treatment chamber; the frame body is arranged in the main drying chamber; and the heat pump evaporator is arranged in the air return channel, a water receiving tray is placed under the heat pump evaporator and the heat pump evaporator is connected with the heat pump condenser.

Description

technical field [0001] The invention relates to the technical field of deep processing of agricultural and sideline products, in particular to a heat pump type fruit and vegetable drying processing system and processing method with zero resource loss. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Fruits and vegetables are the most important crops other than grains in agricultural production. China is the world's largest producer of fresh fruits and vegetables. The moisture content of fresh fruits and vegetables is high, most of which exceed 80%. Improper handling can easily deteriorate and rot. According to the statistics of the Food and Agriculture Organization of the U...
