Example Embodiment

[0061] Example 1:

[0062] A method for drying and processing Porphyra chinensis includes the following steps:

[0063] (1) Pretreatment:

[0064] The altar seaweed is sent to the vegetable washing tank in order according to the conventional drying process of seaweed for washing, shredding in the shredder, blending in the blender, stirring in the mixer, and cake making in the cake maker. The moisture content of the seaweed plate is 86-88%;

[0065] (2)External dehydration in humid environment:

[0066] The seaweed plate of seaweed obtained in step (1) is sent to a water press for one time pressurization, the pressure is 1.5-2.0KPa, and the moisture content of the pressed seaweed plate is 79-80%; The seaweed plate is then sent to the water press for secondary water pressure, the pressure is 1.5-2.0KPa, and the moisture content of the pressed seaweed plate is 75-78%; then the seaweed plate obtained after the second water pressure is sent to the water press Press water three times in th...

Abstract

The invention discloses a method and device for drying and processing of porphyra haitanensis. The main body of the drying processing device is a 'U' shaped pipe, and is provided with a porphyra haitanensis conveying device, a heating device and a ventilation and heat dissipation device; the porphyra haitanensis conveying device is a cart, the heating device comprises a hot air boiler and hot air pipes, and the ventilation and heat dissipation device comprises a fresh vegetable end exhaust port, a dry vegetable end exhaust port and a moisture exhaust port. The method comprises the following steps: washing porphyra haitanensis, chopping, blending, stirring and making cake to obtain a porphyra haitanensis cake; conducting pressing-dehydration of the porphyra haitanensis cake by external forces in a water press by three times, and then placing the porphyra haitanensis cake in a 'U' shaped dry bake channel; drying at 60-70 DEG C for 45-75min to obtain the finished product of the porphyra haitanensis. The prepared finished product has low water content, can meet the conditions of long-term preservation and avoid the situation of secondary re-drying. Scattering of moisture-containing hot gas in all directions is reduced, environmental pollution is reduced, and moisture loss and heat loss in the heating boiler are reduced.

Description

technical field [0001] The invention relates to a drying processing method and a drying processing device of algae laver. Background technique [0002] Porphyra japonica and Porphyra variegata are the two main economic seaweeds cultivated in my country. Porphyra variegata is cultivated in the waters north of the Yangtze River, and Porphyra variegata is cultivated in the waters south of the Yangtze River. The cultivation and processing of Porphyra zebra adopts the Japanese and Korean models: large-scale cultivation, fully automatic mechanized drying and processing, roasted laver and seasoned laver as the main end products. Porphyra laver is one of the cultivated economic seaweeds with the highest output value in the world, with a breeding area of ​​more than 600,000 mu. In recent years, it has been moved northward to the coast of Jiangsu, where it has been cultivated with the local Porphyra variegata, which has produced significant economic and social benefits. [0003] The...
