Embodiment Construction

[0030] Weigh 1000kg of persimmons, put the peeled persimmons on a special plastic tray, keep a distance of 1cm when placing them, one side will be bonded to each other during processing, sterilize in a microwave sterilizer for 5min, and put the sterilized The final persimmons are transferred to the heat pump barn for baking, and the temperature of the hot air is controlled at 70°C at the beginning. After the temperature of the barn reaches 55°C, the temperature of the hot air is adjusted to 55°C, so that the temperature of the barn is controlled at 55°C, and baked for 12 hours . After the persimmon fruit is roasted, turn off the hot air and turn on the natural wind fan for 10 hours of natural ventilation. Turn off the natural wind fan, turn on the hot air, and the air inlet temperature is 60°C. After the temperature of the drying room reaches 45°C, reduce the inlet air temperature, keep the drying room at 45°C, and remove the astringency for 18 hours. After the decolorization...

Abstract

The invention discloses a processing method for dried persimmon. According to the method, microwave sterilization is combined with baking of a heat pump curing barn to process, and the processing method applies microwave sterilization to kill microbes on the surface of persimmon, so that the persimmon is prevented from deteriorating during the processing process, meanwhile polyphenol oxidase (PPO) in the persimmon is killed, and the persimmon is prevented from browning. During the processing process of the dried persimmon, most processes are carried out in the curing barn, the continuity is high, and the product pollution is avoided; the production efficiency of the dried persimmon is improved, the production cost is reduced, the operation is simple, the investment is less, the product quality is controllable, and industrialized mass production is facilitated better.

Description

technical field [0001] The invention belongs to the technical field of fruit processing and production, and in particular relates to a method for processing persimmons. Background technique [0002] Persimmon tastes sweet and is rich in nutrition. Persimmon contains sugar, starch, fat, protein, vitamins, iron, calcium, phosphorus and other nutrients. Dried persimmon is a traditional food of our people and has a long history of processing. However, the processing of persimmons has always been manual production, relying on natural drying, which is labor-intensive and time-consuming. The product quality is difficult to guarantee, and the high-quality product rate is low. Especially in rainy weather, the persimmons will become moldy and rot, causing great losses. Therefore, the research on persimmon processing technology is an urgent problem to be solved in production. It can improve the quality of persimmon, supply the market in advance, and increase farmers' income. [0003]...
