Processing process for preparing nutritional fruit and vegetable powder

Abstract

The invention relates to a processing process for preparing nutritional fruit and vegetable powder and adopts a nutritional fruit and vegetable powder preparation processing device. The nutritional fruit and vegetable powder preparation processing device comprises a preparation box, a drying plate, a movable drying mechanism, a screening guide mechanism and a rotary drying mechanism. The device can solve the following problems in the production and processing process of the nutritional fruit and vegetable powder: a, equipment has large space occupation and small space utilization since dryingis performed by adopting a movable drying mode in a traditional processing process of nutritional fruit and vegetable powder production, the nutritional fruit and vegetable powder is not turned over in the processing process, and the nutritional fruit and vegetable powder is not evenly dried and has a relatively poor drying effect; and b, the dried nutritional fruit and vegetable powder has unevenparticle size since lyophilized and crushed nutritional fruit and vegetable powder is not screened or filtered in traditional nutritional fruit and vegetable powder processing equipment, the qualityof the nutritional fruit and vegetable powder is influenced, and the subsequent taste effect is influenced.

Description

technical field [0001] The invention relates to the field of preparation of nutritious fruit and vegetable powder, in particular to a preparation and processing technology of nutritious fruit and vegetable powder. Background technique [0002] Nutritious fruit and vegetable powder is a powdery solid processed by fresh fruits and vegetables through the existing freeze-drying technology and equipment, pretreatment, quick-freezing, vacuum drying, ultraviolet sterilization, packaging and storage, etc. Due to its low moisture content, storage period The characteristics of long life and high utilization rate of raw materials have gradually entered people's daily life. Because nutritional fruit and vegetable powder increases the nutritional content of the product during the production and processing process, and improves the color and flavor of the product, nutritional fruit and vegetable powder is more and more accepted by people. . [0003] At present, the following problems exi...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a preparation and processing technology of nutritious fruit and vegetable powder, which can solve the following problems in the production and processing of nutritious fruit and vegetable powder: As a result, the equipment space is too large, the space utilization rate is small, and the nutritional fruit and vegetable powder is not turned during the processing process, resulting in uneven drying of the nutritional fruit and vegetable powder, and the drying effect is poor. b In traditional nutritional fruit and vegetable powder processing equipment, due to The freeze-dried and crushed nutritious fruit and vegetable powder is not sieved and filtered, resulting in different particle diameters of the dried nutritious fruit and vegetable powder, which affects the quality of the nutritious fruit and vegetable powder, and then affects the subsequent taste effect
