Abstract

The invention relates to the technical field of processing of vegetables, in particular to a processing technology of quick-frozen vegetables. The processing technology comprises the steps of selecting raw materials, performing cooling, performing cleaning, performing pretreatment, performing blanching, performing air cooling, performing draining, performing quick-freezing, performing packaging and performing cold storage. The processing technology disclosed by the invention has the beneficial effects that the appearance and the freshness of general vegetable raw materials having bright colorare good, and through a color selector, the vegetables having good appearance and freshness can be selected out; in the cooling step, cooling temperature is set to be minus 5-2 DEG C, cooling time isset to be 6-12h, and the vegetable raw materials cooled under the condition can maintain the optimum freshness; in the cleaning step, through a helix cleaning machine, foreign matter of sludge and thelike on the surfaces of the quick-frozen vegetables can be eliminated to the maximum extent, the cleaning effects are better than those with a conveyor belt type cleaning machine in a conventional mode; and in the helix cleaning machine, 0.5%-1% of a calcium carbonate solution is added, so that the vegetable raw materials can maintain brittleness.
