High-efficiency energy-saving furnace

Abstract

The invention discloses a high-efficiency energy-saving furnace and relates to the technical field of tea processing. The top of a shell is provided with an air inlet, and one side of the lower end of the shell is provided with an air outlet; the inner cavity of the shell is provided with a combustion chamber made of heat conducting materials, and a hot air passage is formed between the inner side of the shell and the outer side of the combustion chamber; a smoke outlet pipeline is arranged at the upper end of the combustion chamber and extends out of the shell; a plurality of heat transfer plates made of heat conducting materials are arranged on the upper portion of the inner cavity of the combustion chamber, the heat transfer plates are in staggered arrangement and inclined relative to the inner wall of the combustion chamber, a fuel passage made of heat conducting materials is formed at the lower ends of the heat transfer plates, one end of the fuel passage is communicated with one side of the combustion chamber, and the other end of the fuel passage extends out through the air outlet; a plurality of heat conducting plates made of heat conducting materials are circularly arranged on the outer side of the combustion chamber. By the high-efficiency energy-saving furnace, the problems of low drying efficiency and high fuel consumption of domestic tea drying furnaces can be solved.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a high-efficiency and energy-saving furnace used for drying tea at home. Background technique [0002] Tea processing requires multiple processes, and drying is the last process in tea processing; the purpose of drying is to dehydrate the tea in a certain way, so as to achieve a certain water content and facilitate storage; second, during the drying process, Complex thermochemical reactions occur to ensure that the color, aroma, taste and shape of tea are more perfect. Therefore, drying is one of the key processes for the quality of various teas. [0003] At present, tea farmers in various parts of my country generally process the tea leaves at home after picking them; drying the tea leaves with a drying oven usually takes 5-6 hours to dry 75 kg of tea leaves, which is inefficient and consumes a lot of fuel. Contents of the invention [0004] The object of the present ...
