Description

Technical Field

[0001] The invention relates to the technical field of potato storage and fresh-keeping, in particular to a potato processing device combined with X-ray irradiation processing and a use method thereof. Background Art

[0002] As the fourth largest food crop in the world, the post-harvest storage and processing quality of potatoes directly affect economic benefits and consumer health. Traditional potato storage methods mainly include low-temperature storage, controlled atmosphere storage, and spraying of chemical sprout inhibitors. In recent years, with the application of nuclear technology in the agricultural field, X-ray irradiation technology has gradually attracted attention due to its unique advantages. X-ray irradiation is a physical treatment method that irradiates potatoes with high-energy electron beams or X-rays to destroy the biological activity inside the potatoes, thereby achieving the purpose of sprout inhibition and preservation. Compared with traditional chemical methods, X-ray irradiation has the advantages of no residue, no pollution, and easy operation.

[0003] X-ray irradiation plays multiple roles in potato storage, which not only helps to preserve freshness but also has potential breeding value. X-ray irradiation can effectively inhibit the germination of potatoes during storage. Studies have shown that low-dose X-ray irradiation of 100Gv can significantly reduce the germination rate of potatoes, and this effect has been verified in many potato varieties. For example, in Yellow Rose No. 3, Purple Rose No. 3, Red Rose No. 5 and ordinary potatoes, after 100Gy irradiation, no germination occurred after storage for more than 240 days. Irradiation treatment can also delay the weight loss, hardness loss and VC content loss of potatoes caused by respiration during storage. Specifically, compared with the untreated group, the weight loss rate of potatoes in the irradiated group was significantly reduced, the degree of hardness loss was slowed down, and the VC content loss rate was reduced, which helps to maintain the appearance quality and nutritional quality of potatoes. By inhibiting sprouting and delaying quality deterioration, X-ray irradiation significantly extends the storage life of potatoes, allowing them to maintain excellent quality and taste for a longer period of time.

[0004] The existing X-ray irradiation treatment device for potato storage has some shortcomings when used. First, it cannot turn the potatoes during irradiation, and the irradiation effect is not ideal; second, it cannot grade the potatoes after irradiation, which is not conducive to graded storage.

[0048] The processing method based on the above-mentioned device in this embodiment has the following operating steps: randomly selecting yellow rose No. 3 potatoes on the 15th day after harvest, and sending the harvested potatoes into the loading trough of the annular loading seat through the hopper and the upper sliding tube of the loading assembly; starting the rotary bearing to rotate the annular loading seat at a speed of 2 rpm; adjusting the X-ray irradiator to an irradiation dose of 300 Gy, selecting yellow rose No. 3 tubers with no germination, no lesions, complete tubers, and a tuber weight greater than 50 grams for X-ray radiation treatment, and adjusting the irradiation time according to the volume and density of the potatoes; after the irradiation is completed, starting the rotary bearing again, sending the potatoes out through the unloading outlet pipe and entering the unloading assembly.
