Continuous conveying double-face air drying device for eel roasting and hot air drying method

Abstract

The invention discloses a continuous conveying double-face air drying device for eel roasting. The continuous conveying double-face air drying device comprises a conveying device, an air blowing device, an air drying bin and a filtering device; the conveying device is used for feeding eels needing to be subjected to air drying into the air dying bin, and hot air blown out from the air blowing device conducts air drying treatment on the eels in the air drying bin after being filtered by the filtering device; the air drying bin comprises an air purifying and filtering bin and an air drying mainbin; the filtering device is arranged in the air purifying and filtering bin and comprises a feeding roller, a filter felt and a winding roller; and the air drying main bin is internally provided witha gear ring, a planet gear, a center shaft and a connection rod, the planet gear is provided with a protrusion, and the protrusion can rotate into guide grooves of a four-corner rotation piece and drive the four-corner rotation piece to do angular motion. The invention further discloses an eel air drying method. The continuous conveying double-face air drying device for eel roasting and the eel air drying method have the advantages that feeding is conducted, the air drying continuity is high, automatic turning over can be achieved, and the air drying cleanliness is high.

Description

technical field [0001] The invention relates to the technical field of grilled eel processing, in particular to a continuous conveying double-sided air-drying device and a hot-air drying method for grilled eel processing. Background technique [0002] Eel is rich in vitamin A and vitamin E, the content is 60 times and 9 times that of ordinary fish respectively. Among them, vitamin A is 100 times that of beef and more than 300 times that of pork. Rich in vitamin A and vitamin E, it is of great benefit to prevent vision deterioration, protect the liver, and restore energy. Other vitamins such as vitamin B1 and vitamin B2 are also rich in content. Eel is also rich in "good" fats. The phospholipids contained in it are indispensable nutrients for brain cells. In addition, eel also contains DHA and EPA (deep-sea fish oil components, DHA is docosahexaenoic acid, EPA is eicosapentaenoic acid), commonly known as "brain gold", the content is higher than other seafood and meat , w...

Problems solved by technology

This technical solution has the following deficiencies: one, the fish and shrimp are relatively static in the drying net during the air-drying process, and the wind direction blows the fish and shrimp from bottom to top, causing the degree and efficiency of the lower surface of the fish and shrimp to be far greater than The degree and efficiency of the upper surface of the fish and shrimp cause uneven drying, which affects the drying efficiency and effect; and the method of manually turning over the fish and shrimp in the drying net to improve the drying effect still consumes labor, The technical problem of inconvenient operation; secondly, before air-drying, the fish and shrimp are pre-placed behind the drying net, and then air-dried uniformly, resulting in that the two processes of feeding and air-drying are separated successively, which cannot meet the requirements of feeding and air-drying at the same time. The technical effect causes the continuity of processing to be weak; thirdly, although the technical scheme mentions that the first air inlet of the temperature control room and the third air outlet of the air cleaning room are provided with protective nets, which can prevent mosquitoes, flies and Flocks and other sundries enter the drying room to ensure that fish, shrimp and other seafood are always air-dried in a clean environment, and the sanitation is better. However, it is difficult for the protective net to filter fine dust and suspended particles in the air; After the net is used for a long time, it needs to be replaced and cleaned. When the drying room needs to be used continuously for a long time, the replacement or cleaning of the protective net will undoubtedly interrupt the continuous process
