Fish meal drying and dehumidifying device

Abstract

The invention discloses a fish meal drying and dehumidifying device which comprises a first independent space and an exhausting body. The first independent space comprises a conveying part which comprises a conveying piece, and materials needing to be dried and dehumidified are placed on the conveying piece. The exhausting body comprises a first exhausting piece. The first exhausting piece is connected with the lower end of the first independent space and comprises a protecting piece and a first exhausting pipe, and hot air is introduced into the first independent space through the first exhausting pipe, and dries and dehumidifies the materials on the conveying piece. According to the fish meal drying and dehumidifying device, closed circulation is adopted for carrying out dehumidifying, and exhausting of waste gas and odor is avoided in the dehumidifying process; and moreover, external heating power supply is not needed, installing is easy, the adjustment period is short, and 3.2-3.4 L of water is dehydrated per 1 KWH on average. The whole drying and dehumidifying production assembly line can treat 25-150 tons of high-moisture fish meal squeezed wet feed every day, can increase or decrease the yield according to needs of users, is free of the influence of external environment temperature and humidity, and meets the use requirement for drying and dehumidifying the fish meal in various areas.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning, in particular to a fishmeal drying and dehumidifying device. Background technique [0002] At present, the fishmeal processing industry usually adopts two times of steam drying in the production of whole deboned fishmeal, and three times of steam drying is generally used in the production of half-debonded or full-fat fishmeal, and finally the high-temperature fishmeal is cooled. [0003] However, this traditional production process and equipment usually have high steam consumption, large discharge of smelly waste heat steam, difficult treatment and poor effect. Moreover, due to the long-time and high-temperature drying in the traditional method, the quality of the fishmeal produced is low, the amino acids in the fishmeal are largely destroyed, the effective protein content is low, and the cost performance of the product cannot be improved. At the same time, it is diffi...

[0003] However, this kind of traditional production process and equipment usually has high steam consumption, large discharge of smelly waste heat steam, difficult treatment and poor effect

Moreover, due to the long-time and high-temperature drying in the traditional method, the quality of the fishmeal produced is low, the amino acids in the fishmeal are destroyed in large quantities, the effective protein content is low, and the cost performance of the product cannot be improved.

At the same time, it is difficult for employees to operate and control, and the cost of equipment maintenance is high
