Fresh longan fruit immersion cleaning, sand shaking, peel wiping and drying integrated equipment and application method of fresh longan fruit immersion cleaning, sand shaking, peel wiping and drying integrated equipment

Abstract

The invention relates to fresh longan fruit immersion cleaning, sand shaking and peel wiping and drying integrated equipment and an application method. The equipment comprises a rack, and a driving mechanism, a rotating barrel body, an automatic sand adding mechanism, an automatic water injection mechanism and a drying mechanism are installed on the rack; the drying mechanism is arranged in the rotary barrel body and regularly dries the fresh longan fruits in the rotary barrel body, the three working procedures of immersion cleaning, sand shaking and peel wiping and drying are combined and sequentially completed on one device, labor force and work and auxiliary time are greatly reduced, and the productivity and economic benefits are improved; the drying procedure is completed under the condition that the fresh longan fruits rotate and roll, compared with a layer-by-layer paving type drying mode of the fresh longan fruits, the fresh longan fruits are heated more uniformly, the heat efficiency is higher, the drying quality is better, meanwhile, under the control of a PLC, the hot air flow and temperature precision adjusted by an air heater and a proportional flow valve is high, and the adaptability to the drying technology is high; and the silica gel plates are completely laid on the inner side of the rotary barrel body, so that temperature resistance and heat preservation can be achieved in the working process.

Description

technical field [0001] The invention relates to the technical fields of dipping, shaking sand and rinsing and drying of fresh longan fruits, in particular to an integrated device and application method of dipping, rinsing and drying of fresh longan fruits. Background technique [0002] Dried longan is a nutritional supplement that is well received by consumers, and has a large consumer market in all parts of my country. The fresh longan fruit matures in the high temperature summer, the harvest period is short and the storage is not resistant, the fresh sales pressure is high, and the price fluctuates violently. Compared with fresh longan, dried longan can be stored for a longer time, is convenient to transport, can expand the sales range and can be made into various high value-added products, further increasing the income of fruit farmers. At present, the number and scale of dried longan processing enterprises in my country are small, mainly scattered in the longan producin...

AI Technical Summary

Problems solved by technology

[0004] At present, the two processes of soaking and sand rubbing are still largely processed by the traditional bamboo cradle method, which is completely dependent on labor, while the drying process is mostly dried in a shelf drying room, and there are serious production problems. Problems such as backward equipment, difficult control of process and technical standards, low efficiency and high cost have greatly restricted the technical progress of dried longan processing and the development of the industry
