Oil-fired tea dryer

Abstract

The invention belongs to the technical field of tea processing machinery and provides an oil-fired tea dryer. The oil-fired tea dryer comprises a dryer box body, a hot air generating system, a tea feeding system and a tea discharging system, wherein the hot air generating system is arranged above the dryer box body and is communicated with the dryer box body, the tea feeding system is arranged on one side of the dryer box body, and the tea discharging system is arranged at the bottom of the dryer box body. A tea conveying system is arranged in the dryer box body. The tea conveying system comprises at least two conveying layers. The feeding end of the tea conveying system is matched with the tea feeding system. The discharging end of the tea conveying system is matched with the tea discharging system. The hot air generating system, the tea feeding system, the tea discharging system and the tea conveying system are controlled by a control system which is arranged on the dryer box body. According to the oil-fired tea dryer, the structure of the dryer box body is optimized, the path through which hot air enters the dryer box body is shortened, the inner ventilation of the box body is improved, convective heat transfer coefficient is increased through layered conveyance and air intake, and energy loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of tea processing machinery, and in particular relates to a fuel-fired tea drying machine. Background technique [0002] At present, the drying methods used in production mainly include drying, frying, drying, etc., and the corresponding supporting equipment includes dryers (hand-pulled louver dryers, mesh belt dryers, chain plate dryers, etc.), Frying and drying machines (pan-type frying and drying machines, bottle-type frying and drying machines, cylinder-type frying and drying machines, etc.) It was gradually eliminated due to its shortcomings, and now it is only used to make low-grade teas such as black hair tea. Drying and frying are currently the most widely used in production, and the flavor and quality of the processed products have their own characteristics. According to the research of Yin Junfeng et al., the frying and drying process is helpful to obtain a sharp aroma quality, while drying is co...

AI Technical Summary

Problems solved by technology

Firewood and coal-fired drying equipment are gradually replaced by other methods due to serious environmental pollution. Gas-fired drying equipment has disadvantages such as high initial investment and poor temperature control stability. It has advantages such as convenient operation, but the thermal efficiency is low and the operating cost is high, which is unbearable for ordinary small and medium-sized tea production enterprises! Therefore, the industry has never stopped improving and perfecting traditional drying equipment, and plans to develop a new type of drying equipment with precise temperature control, high thermal efficiency, easy operation and large production capacity.
