Problems solved by technology

[0005] However, it is not easy to process starch from taro. Taro is rich in vegetable gum, and taro starch particles are very fine. After the two are mixed in water, it is extremely difficult to separate them with existing technology. This is why taro cannot enter starch for a long time. Root Causes in Machining Fields

Embodiment Construction

[0020] The production of taro starch consumes a lot of water, so it is necessary to choose a place with convenient water supply and drainage and transportation, design and build a factory according to the production process and technical requirements, and must build supporting wastewater treatment facilities.

[0021] After the production line has been built and debugged, it can be produced according to the steps and process requirements determined by the present invention:

[0022] 1. Sol, wash, peel and chop the taro, flow into the pulverizer with water and pulverize it into a slurry, slowly add diluted lye under stirring, adjust the pH value to 9.5, keep for 45 minutes to dissolve the taro gum, and pulverize The amount of water added in is 3 times of the weight of taro;

[0023] 2. Filtration. Use a double-layer rotary vibrating screen to filter the sol-treated slurry in two stages. The first stage is 60 mesh, and the second stage is 200 mesh. During the filtration, add wat...

Abstract

This invention relates to taro starch production process, belongs to subsidiary agricultural products deep processing region. The invention mainly transit sol, filtration, chromatography, separation, dryness etc. steps to extract taro starch.

Description

1. Technical field [0001] The invention belongs to the technical field of deep processing of agricultural and sideline products, and relates to a method for producing taro starch. 2. Technical background [0002] Taro, Araceae, perennial herb, is an annual cultivated crop, and likes high temperature and humidity. It is widely planted in southern my country, especially in Guangdong and Guangxi. [0003] As a vegetable, taro has long been known, but few people thought of it as a starchy raw material. In fact, taro contains 16-17% starch, which is similar to that of sweet potato. Sweet potato has long been used as one of the raw materials of the starch industry and has entered deep processing, but taro has been excluded from the starch industry. It is sold as a vegetable in the market, but now there are many varieties of vegetables, and people have a lot of choice. After all, the sales volume of taro is limited. Due to the difficulty in sales, many farmers have given up planti...
