Abstract

The invention discloses a low-pressure superheated steam drying system and technology and belongs to the field of processing of aquatic products. The system comprises a drying box; a tray for accommodating to-be-dried products is arranged in the drying box; a steam distributor is arranged below the tray and comprises multiple steam channels and a plurality of steam outlets, the plurality of steam outlets are opposite to the bottom of the tray, the multiple steam channels are connected with a steam heater, the steam heater is connected with a steam generator, steam generated by the steam generator is heated by the steam heater to become superheated steam, and the superheated steam enters the drying box by the aid of the steam distributor to dry the to-be-dried products; and an exhaust outlet is arranged at the top of the drying box and is connected with a condenser.

Description

technical field [0001] The invention belongs to the field of aquatic product processing, and in particular relates to a drying system and process for drying aquatic products. Background technique [0002] In order to increase the shelf life, many aquatic products need to be processed into dry products. For example, sea cucumbers belong to the invertebrate echinodermata sea cucumber class. Sea cucumber has no cholesterol, high protein, low fat, low sugar and is rich in various essential amino acids, vitamins, essential fatty acids and macro and trace elements. It is a health food with high nutritional value. Sea cucumbers are harvested seasonally and are easily autolyzed, so they can only be raised or processed for a short period of time after going out to sea. At present, the processing of sea cucumbers is mainly dried. According to statistics, 90% of sea cucumbers in the world are processed into various dried products. [0003] The traditional sea cucumber drying process...
