Embodiment

[0023] ①Turn on the steam generator 1 to make the steam pressure reach 0.18MPa; ②Open and set the blanching temperature of the automatic control box 2 to 120℃ and the airflow speed of 15m / s; ③Adjust the normally open valve 4 and the normally closed valve 5 to reach the setting Set the relative humidity of 40%; ④Put the sea cucumber tray 15 with sea cucumbers into it, and blanch it for 25 minutes; ⑤Open the normally open valve 4, close the normally closed valve 5, and remove the humid air in the air flow channel 9 and the air distribution chamber 10, And adjust the drying temperature to 70°C, the air flow speed to 20m / s, and dry for 9 hours. After the dried sea cucumbers are naturally cooled and packaged, they are placed in a dry and protected warehouse for sale.

[0024] In the above-mentioned embodiment, the steam generator 1 is high-pressure steam generated by electrically heating deionized water.

Abstract

The present invention discloses a cucumber drying method and device with air spray impact belonging to the technical field of food processing. The technical proposal comprises that the viscera of cucumber is removed and the cucumber is put in a steam environment of the relative humidity of 10 to 50 percent, temperature of 90 to 200 Celsius degrees, air speed of 3 to 20m/s for 5 to 40 minutes to thoroughly destroy the autoenzyme; and then the cucumber is dried under an environment of the temperature of 40 to 80 Celsius degrees and air speed of 5 to 20 m/s for 5 to 16 hours. The device comprises a steam generator (1), an automatically controlled box (2), a steam duct (3), an air circulation duct (6), a fan (7), an electric heater (8), an air duct (9), an air distribution chamber (10), a temperature and air speed sensor (11), a humidity sensor (12), a nozzle (13) and a cucumber tray (15). The cucumber dried with the present invention is characterized by no nutrition loss and the properties of saving water, energy and environmental protection and the automatic control is realized in the process.

Description

Technical field [0001] The invention relates to a method and device for drying sea cucumbers by gas jet impacting, in particular to a method and equipment for processing sea cucumbers without nutrient loss, and belongs to the technical field of seafood processing. technical background [0002] Sea cucumbers are called ginseng in the sea. The book "Supplements to Compendium of Materia Medica" has this description: "Sea cucumbers are warm tonic, enough for the enemy's ginseng, hence the name sea cucumber" (Zhao Xuemin (Qing). Supplements to Compendium of Materia Medica (Vol. 10) [M ]. Beijing: The Commercial Press, 1955, 495). Sea cucumbers are high-protein, low-cholesterol, and rich in various physiologically active substances. The sea cucumber acid mucopolysaccharide contained in it can prevent arteriosclerosis and is one of the most effective substances for reducing blood lipids, anti-aging, and repairing old myocardial infarction (Wu Fangyi, Yang Jinyuan, Zhou Peiwen. Stichopus...
