Dry hot air dehydration processing method of low-salt radish

Abstract

The invention discloses a processing method of low-salt dried turnip by adopting hot-air dewatering. The processing method comprises the following steps: (1) cleaning fresh turnip materials, and then splitting into turnip strips, turnip slices or turnip blocks; (2) carrying out hot-air dewatering on the turnip pretreated in the step (1); (3) carrying out low-salt salting on the turnip treated by hot-air dewatering in the step (2); and (4) putting the turnip salted with low salt in a salting jar, and compacting and sealing for salting in the jar. The processing method disclosed by the invention has the advantages that (1) the safety and the stability of the quality of a dried turnip product can be effectively guaranteed, the traditional flavor of the dried turnip is retained and low-salt content is realized; (2) the use amount of the salt is reduced, and bleaching for desalting is not needed, so that the cost is saved; (3) no high-salt salting liquid and bleaching desalting liquid are produced in the production process, so that the pollution to the surrounding environment is avoided; and (4) mechanical dewatering equipment can be adopted, a hot-air dewatering production line is established, no influence is caused by weather, and continuous, standardized, large-scale and modern-factory production is realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a low-salt radish dry-hot-air dehydration processing method. Background technique [0002] Dried radish is an advantageous and characteristic processed agricultural product in some places in Zhejiang Province (Xiaoshan District, Hangzhou City), which has anti-inflammatory, heatstroke prevention and appetizing effects. At present, the main processing methods of dried radish include two processing techniques: open-air natural drying and dehydration and high-salt pickling and dehydration. The dried radishes processed by the open-air natural drying and dehydration process are bright yellow in color, crisp and tender, and have good quality. However, the open-air drying and dehydration process occupies a large area, and the cost of manual drying is high. It is heavily dependent on the weather and cannot achieve continuous and standardized processing....

Problems solved by technology

The dried radishes processed by the open-air natural drying and dehydration process are bright yellow in color, crisp and tender, and have good quality. However, the open-air drying and dehydration process occupies a large area, and the cost of manual drying is high. It is heavily dependent on the weather and cannot achieve continuous and standardized processing. And it is easy to be polluted by air dust, etc., and the hygienic quality is unstable. It cannot realize continuous and large-scale processing in factories. It is only suitable for home-made small quantities.

The high-salt pickling and dehydration process uses the high osmotic pressure of table salt to achieve the purpose of dehydration, and realizes the large-scale, continuous and standardized factory processing and production of dried radish. However, this process has the following defects: 1. The amount of table salt is large, and the product has high salinity , can not meet the low-salt requirements; 2. Secondary processing of rinsing and desalting is required, which not only causes product nutrition loss and increases production costs, but also high-salt pickling liquid and rinsing and desalting liquid cause great pollution to the surrounding environment; 3. Product quality declines , can not reach the excellent quality of natural drying and dehydration process
