Problems solved by technology

2. Effects on endogenous ethylene synthesis in fruits
4. Effect on protein synthesis
The heating method provided by this heat treatment device for post-harvest antiseptic preservation and sterilization of citrus is to use the heater for direct electric heating, which is equivalent to the heating principle of "resistance heater (commonly known as fast heat)", but this heating method consumes electricity High, energy cost increases

Abstract

The invention relates to the technical field of post-harvest processing and storage of agricultural products, in particular to a heat pump device for preservation and sterilization of oranges and a heat treatment method. The device consists of a heat pump device system, a heat preservation box body system and a temperature detection system; in the heat treatment process, the oranges are placed into a heat preservation container, a heat treatment device is started, the heat pump device prepares hot water to be stored in a heat preservation hot water tank, circulating water supply is carried outon the heat preservation container, a plurality of temperature acquisition points are arranged in the heat preservation container, the average temperature difference value between the outer region average temperature and the inner region average temperature of the oranges is less than + / -0.5 DEG C, a computer detects the temperature of each temperature acquisition point in the heat preservation container, and the obtained maximum temperature difference of all the measuring points is less than + / -0.5 DEG C; and after 30 minutes, all the working systems are stopped, the treated oranges are taken out, the water is discharged to the heat preservation hot water tank for storage for later use, and the heat treatment process is completed. The method has the advantages that preservation and sterilization of the oranges can be realized, the storage period of the oranges can be prolonged, the disease resistance of the oranges is improved, and the problem of adjusting the heat treatment yield offruits can be solved.

Description

technical field [0001] The invention relates to the technical field of post-harvest processing and storage of agricultural products, in particular to a heat pump device and heat treatment method for citrus antiseptic preservation and sterilization. Background technique [0002] Fruit postharvest rot has brought great losses to the world's fruit production. According to incomplete statistics, the postharvest rot of fruits generally reaches 20%-30%. Environmental factors in tropical areas are more conducive to the occurrence of postharvest diseases, and the postharvest rot rate of fruits is as high as 50%. Heat treatment is one of the postharvest preservation methods that have attracted much attention in recent years, especially as the problem of pesticide residues has become increasingly serious. Scholars have begun to pay attention to this non-toxic and pesticide-free fruit preservation method, and research in related fields has become quite active. [0003] The applicatio...
