Efficient laver drying device based on gas flow velocity negative pressure

Abstract

The invention provides an efficient laver drying device based on gas flow velocity negative pressure, which relates to the technical field of laver drying. The invention discloses the efficient laverdrying device based on gas flow velocity negative pressure, which comprises a drying furnace, an air inlet is fixedly connected to the periphery of the drying furnace, a heating resistance wire is wound in the outer wall of the drying furnace, a first through hole is formed in the inner side of the drying furnace, an air blowing pipe is fixedly connected to the center of the drying furnace, and asecond through hole is formed in the periphery of the air blowing pipe. The invention discloses the efficient laver drying device based on gas flow velocity negative pressure, the laver spreading efficiency is greatly improved, compared with the prior art, the laver spreading is more time-saving and labor-saving, loss of nutritional ingredients of laver is prevented, advanced coking of the upper surfaces of laver cakes due to high dehydration speed is avoided, flowing of gas in the drying furnace is guaranteed, the drying effect is improved, the moisture regaining phenomenon is avoided, the drying efficiency is improved, and laver in the drying furnace is heated more uniformly.

Description

technical field [0001] The invention relates to the technical field of laver drying, in particular to a high-efficiency laver drying device based on gas flow rate and negative pressure. Background technique [0002] Porphyra is a kind of seaweed that grows in the intertidal zone. Its distribution covers cold, temperate, subtropical and tropical seas. Contains dietary fiber, multivitamins, calcium, potassium, magnesium and other trace elements, and also contains algae-specific phycobiliprotein, which has high nutritional value. Laver contains a lot of water after harvesting. In order to improve the storage time of laver, it is convenient For transportation and sale, laver needs to be dehydrated and dried after harvesting. [0003] At first, the dehydration of laver was done by artificial drying, but due to the heavy workload, long drying cycle, and easy to be affected by the weather, it was gradually replaced by various intelligent drying equipment. In order to facilitate th...

Problems solved by technology

[0003] At first, the dehydration of laver was done by artificial drying, but due to the heavy workload, long drying cycle, and easy to be affected by the weather, it was gradually replaced by various intelligent drying equipment. In order to facilitate the packaging of dried laver, Before drying the laver, it is necessary to lay the laver into a round cake of a certain size, but the traditional drying equipment still needs manual operation for laying the laver, which is time-consuming and laborious, and in the process of drying a large amount of laver, it is easy The temperature difference due to different areas reduces the drying effect of laver, and the traditional drying equipment is to speed up the drying and has a strong seal, which makes the air fluidity poor and the evaporated gas inside cannot be discharged well. After drying, it is easy to regain moisture, which is easy to cause rust and damage to the machine
