Drying and sterilizing apparatus for dehydrated vegetable processing use, and drying and sterilizing method of dehydrated vegetables

Abstract

The invention discloses a drying and sterilizing apparatus for dehydrated vegetable processing use. The drying and sterilizing apparatus for dehydrated vegetable processing use comprises a machine body; a material inlet tube is arranged at a top end of the machine body; a material outlet tube is arranged at a bottom end of the machine body; valves are mounted both on the material inlet tube and the material outlet tube; a rotating rod is rotationally installed inside the machine body; spiral blades are mounted on the outer circumference of the rotating rod; a plurality of uniformly arranged nozzles are mounted on an inner wall of the machine body; input ends of the nozzles are connected with an external input pipe; the input pipe is connected with an external steam generator; an air inletpipe is connected with the input pipe; and the air inlet pipe is connected with an external hot air pump. The drying and sterilizing apparatus for dehydrated vegetable processing use integrates vegetable dehydrating-drying equipment and sterilization equipment, so that vegetable processing efficiency is improved with good vegetable drying and sterilizing effects achieved; and moreover, the dryingand sterilizing apparatus for dehydrated vegetable processing use is simple in processing process, and improved in production efficiency.

Description

technical field [0001] The invention relates to the technical field of dehydrated vegetables, in particular to a drying and sterilizing device for processing dehydrated vegetables and a drying and sterilizing method. Background technique [0002] Dehydrated vegetables, also known as rehydrated vegetables, are a kind of dried vegetables made by washing and drying fresh vegetables to remove most of the water in the vegetables. The original color and nutrient content of the vegetables remain basically unchanged. It is not only easy to store and transport, but also can effectively adjust the seasons of low and high seasons for vegetable production. When eating, just immerse it in clean water to restore it, and retain the original color, nutrition and flavor of the vegetable. During the processing of dehydrated vegetables, the raw materials need to be dehydrated and sterilized, but the current sterilization equipment and dehydration equipment are mostly set separately, and the ...

AI Technical Summary

Problems solved by technology

During the processing of dehydrated vegetables, the raw materials need to be dehydrated and sterilized, but the current sterilization equipment and dehydration equipment are mostly set separately, and the vegetables are prone to secondary infection during the intermediate transfer process, resulting in poor product quality
