High swelling speed undaria pinnatifida leaf drying processing method

Abstract

The invention discloses a high swelling speed undaria pinnatifida leaf drying processing method, which is simple in operation, saves energy sources and improves production efficiency. The method comprises the following steps in turn: selecting pickled undaria pinnatifida, desalting by a drum desalting machine, combing the undaria pinnatifida and then cutting the undaria pinnatifida with a cutting machine; continuously washing the cut undaria pinnatifida with filtered clean seawater in a seawater filtrating chain type steam bubble washing machine twice; dewatering the washed undaria pinnatifida for 3 to 5min by using a hydraulic press; soaking the dewatered undaria pinnatifida in 3 mass percent saline water for 25 to 35s, and then dewatering the soaked undaria pinnatifida for 3 to 5min; breaking up the dewatered undaria pinnatifida for 1 to 2min by using a breaker; delivering the undaria pinnatifida to a three-segment drying machine by a fan, and drying for 30 to 40min at the temperature of 120 to 130 DEG C; delivering the undaria pinnatifida into a drum drier for drying twice at the temperature of 120 to 130 DEG C for 25 to 30min respectively; and packaging after wind selection, screening, manual selection, static selection and metal selection.

Description

Technical field: [0001] The invention relates to a processing method of wakame, in particular to a processing method of dried wakame leaves with simple operation, energy saving, improved production efficiency and fast rebubbling speed. Background technique: [0002] Wakame is one of the edible seaweeds. It is a natural treasure house of trace elements and minerals. It contains more than a dozen essential amino acids, calcium, iodine, zinc, selenium and vitamins. It is extremely beneficial to children's bone and intellectual development. Because of its high nutrition and low calorie characteristics, it has significant effects in weight loss, cleaning the intestines, protecting the skin, delaying aging, etc., and can prevent many diseases. It is known as the king of seaweed, beauty dish, health dish, green Sea cucumber etc. The existing wakame processing methods include freezing, salting, dry products, etc., because freezing and salting wakame can only be processed according ...

Problems solved by technology

Although 90% of the leaves of dried wakame can be unfolded within 30-60 seconds, its processing method has no desalination process, and the high salt content not only directly affects the quality of the dried product, but also prolongs the drying time, especially after initial drying, salt water, etc. The processing method of washing and then final drying is to rehydrate the initially dried wakame once and finally dry it again, which further prolongs the drying time. The drying times of the two examples are 5 hours and 3 hours respectively, which not only wastes energy, but also reduces production efficiency. Low, and it will also cause the loss of nutrients and surface hardening and drying of wakame
