Technical Field

The invention relates to the technical field of cherry postharvest treatment, in particular to a small-sized sweet cherry commercialized treatment device.

Background

The sweet cherries are one of the main fresh fruits in China, the yield and the consumption are increased year by year in recent years, and according to incomplete statistics, the planting area of the sweet cherries in China reaches 320 ten thousand mu and the yield is nearly 100 ten thousand tons by 2020. The sweet cherries are high in economic value, are mainly sold in the form of fresh fruits, are easily lost in commodity due to rotting in high-temperature seasons when being sold on the market, if the fresh cherries are not precooled in time and are kept fresh, the loss of the sweet cherries caused by rotting and quality deterioration in the whole country is more than 10 million tons, and the economic loss is billions of yuan.

Precooling the picked sweet cherries in time can reduce the respiratory intensity, the activity of various enzymes and the growth of microorganisms, delay aging and keep good flavor and taste. The sweet cherry precooling mainly comprises three modes of standing precooling in a cold storage, forced air cooling and water precooling. The water pre-cooling is the development trend of the pre-cooling of the sweet cherries, and has the advantages of high speed of water pre-cooling and cooling, high efficiency, low energy consumption and less water loss of the fruits. Spraying with 0-3 deg.C cold water for 15min to reduce the temperature of sweet cherry to 3-5 deg.C.

The grading of sweet cherries is an important means for improving the quality of commodities and realizing standardization. The grading according to the size is the most common grading method for sweet cherries in China, the manual grading and the roller grading are mainly used, the manual grading efficiency is low, each person can only grade 100kg per day on average, and the roller grading easily causes mechanical damage. Photoelectric classification is the most advanced classification method at present, and can be classified according to shape, size, color and luster and defective condition. In China, photoelectric grading equipment is tried on small fruit grading, but the commercial application is very few. The friction between the machine and the sweet cherries in the grading process is easy to cause mechanical damage, and the friction damage of the sweet cherries can be reduced by using air flow and running water conveying.

Decay by fungi causes the most serious losses in the storage and transportation of sweet cherries. The coating of the biological preservative for the sweet cherries can inhibit the growth of mold, reduce water evaporation and respiratory metabolism and play a good role in preserving and preserving the sweet cherries. After the sweet cherry is coated, dehumidification is carried out at low temperature, the surface moisture is removed, and the preservative is formed on the surface of the cherry.

Fresh-keeping sweet cherry by modified atmosphere packaging, by changing CO in packaging environment₂And O₂Can slow down the metabolic intensity and inhibit the growth of microorganisms. Wherein O is₂The concentration has obvious influence on the respiration intensity of the sweet cherry when the concentration is O₂At concentrations below 10%, the respiration intensity of the fruit decreases dramatically. Sweet cherry to CO₂Non-sensitive, high concentration of CO₂The treatment can inhibit endogenous ethylene production, inhibit Peroxidase (POD) and polyphenol oxidase (PPO) activity, and reduce malondialdehyde content, thereby inhibiting sweet cherry ripening and aging.

At present, no sweet cherry commercialized treatment equipment patent is searched, and only a sweet cherry precooling equipment patent and a plurality of fruit grading equipment patents are searched.
