Abstract

The invention discloses an energy-saving food drying baking room. The room comprises a baking room, an air inlet and an air outlet, wherein a first scavenging valve is arranged at the air inlet; a second scavenging valve is arranged at the air outlet; a heat-pipe heat exchanger is arranged between the air outlet and the air inlet and used for recycling waste heat; a variable-frequency circulating fan is arranged between the top layer of the baking room and a ceiling and used for controlling the air quantity in the drying baking room; and a heater is arranged in front of the circulating fan and used for raising the temperature in the drying baking room. The baking room has the advantages of overcoming the defects of high energy consumption, high pollutant discharge and the like in the conventional food drying process, enhancing energy utilization ratio, further reducing energy consumption and lowering cost.

Description

technical field [0001] The invention relates to a drying and baking room, in particular to an energy-saving food drying and baking room. Background technique [0002] High energy consumption and serious impact on product quality are the two most important problems in food drying. Drying is an operation with high energy consumption. There is still a great contradiction between the economy of drying and product quality. How to obtain high-quality dehydrated and dried products with low energy consumption and low cost is an urgent research in the current food drying research. It is also one of the biggest challenges in the research and development of drying technology. At present, in the food drying industry, large-scale drying still relies on burning coal, petroleum and other fossil fuels to provide heat, which seriously pollutes the environment. [0003] Therefore, the fundamental purpose of the energy-saving optimization design of the drying system is to make full use of ne...
