Method for manufacturing dehydrated sweet potato vine powder

Abstract

The invention relates to a method for manufacturing dehydrated sweet potato vine powder, belonging to the field of food processing technologies. The method comprises steps of selecting materials, chopping by a machine, washing and removing peel through ultrasonic, selecting by a machine for the first time, grading manually, steam exploding, rolling into powder, drying, sorting and packaging. The method comprises the step of steam exploding, under huge pressure difference, saturated steam carries out adiabatic expansion on the sweet potato vine so as to ripen the sweet potato vine, and the steaming step is omitted, so that energy consumption is reduced, after steam exploding, the material is cooled to room temperature rapidly, the step of cooling the material can be saved and the next production chain can be directly carried out, the production speed can be accelerated, labor cost is reduced, the cost price of the equipment is saved, and the method is sanitary.

Description

technical field [0001] The invention relates to a method for processing dehydrated potato and rattan powder, which belongs to the field of food processing. Background technique [0002] Dehydrated vegetables are convenient to eat, have low water content, are easy to transport, and have a long storage time, which can effectively adjust the off-peak season of vegetable production. [0003] According to the applicant's understanding, the following problems exist in the processing process of the existing dehydrated vegetables: [0004] 1. The processing of dehydrated vegetables generally includes a cooking process, and the cooking process takes a long time. Generally, the time is recorded in hours, which wastes energy and time; at the same time, the steps after the cooking process need to cool down the cooked dehydrated vegetables. use, further wasting energy and time; [0005] 2. When low-temperature drying is used for processing dehydrated vegetables, it is necessary to cool...

AI Technical Summary

Problems solved by technology

[0004] 1. The processing of dehydrated vegetables generally includes a cooking process, and the cooking process takes a long time. Generally, the time is recorded in hours, which wastes energy and time; at the same time, the steps after the cooking process need to cool down the cooked dehydrated vegetables. use, further wasting energy and time;

[0005] 2. When processing dehydrated vegetables with low-temperature drying, it is necessary to cool down the dehydrated vegetables in advance before using them. The production cycle is long and the production efficiency is low.
