Description

A kind of tea drier

Technical field

This utility model is related to tea-processing equipment field, more particularly to a kind of tea drier.

Background technology

In Tea Processing production process, need to dry Folium Camelliae sinensis using dehydrator, to remove the moisture in Folium Camelliae sinensis, The moisture in tea cell is reduced, its activity is reduced and is removed the semi permeability of cell membrane, it is ensured that following process can be normal, suitable Carry out sharply.Existing dehydrator includes that into and out of material mouth and into and out of air port band screen cloth in which is heating cabinet above screen cloth, sieves Housing of the side off the net for hot blast storehouse, after the heating cabinet entered above screen cloth from charging aperture so as to Folium Camelliae sinensis, hot blast is sent from air inlet Enter in the hot blast storehouse below screen cloth, then the air outlet after hot blast is dried to Folium Camelliae sinensis thereon by screen cloth, from the top of feed bin Discharge, as the air outlet at the top of feed bin is provided with air exhauster, air draft is very fast, except containing certain moisture content and dirt in the wind so discharged Outside angstrom, also with higher temperature, therefore so it is expelled directly out necessarily wasting heat resource, is unfavorable for the energy-conservation drop of tea-enterprise Consumption, affects the economic benefit of tea-enterprise.It is therefore desirable to being improved to prior art.

Utility model content

The purpose of this utility model is in view of the shortcomings of the prior art, there is provided a kind of heat recovery of tea drier Device, makes full use of the air exhaust waste heat of tea drier, and reducing energy consumption is cost-effective.

The technical solution of the utility model：

A kind of tea drier, comprising baking oven, hot air generator, connects one at the air inlet of the hot air generator Root heat-exchange tube, is entangled a sleeve pipe, is connected with the air vent of baking oven after the bottom bending of sleeve pipe is L-shaped outside heat-exchange tube Connect, the position of sleeve pipe bending is less than the air vent of baking oven, and the two ends of heat-exchange tube pass the side wall of sleeve pipe and are weldingly fixed on set Guan Shang, heat-exchange tube are set to air entry near one end of cannula tip, and heat-exchange tube is sent out with hot blast near one end of casing shoe The air inlet of generating apparatus is connected, and the position of sleeve pipe bending is provided with a discharge outlet.

Further, the heat-exchange tube is aluminum spiral condensing tube.

Further, described sleeve pipe outer wrapping one layer of heat preservation material.

Further, the air entry arranges dust removal and filtration equipment.

Further, temperature display devices are provided with the baking oven.

Further, a header tank is placed below the discharge outlet.

Prior art is compared, and this utility model is saved to make full use of the air exhaust waste heat of tea drier, reducing energy consumption Cost, arranges a sleeve pipe by the exhaust ports in baking oven, is provided with spiral heat-exchange tube, by using baking oven in sleeve pipe It is middle to discharge hot and humid gas, preheat to flowing through the cold air in the entrance hot air generator of heat-exchange tube, make Initial temperature into the air in boiler is higher, and less energy resource consumption can make into the gas temperature in baking oven to reach Standard, so can be economized on resources with reducing energy consumption, improve the economic benefit of tea processing factory.

Description of the drawings

Fig. 1 is this utility model structural representation.

Specific embodiment

This utility model is expanded on further below in conjunction with the accompanying drawings.It should be understood that these embodiments are merely to illustrate this practicality newly Type rather than restriction scope of the present utility model.In addition, it is to be understood that after the content for having read this utility model instruction, this Art personnel can be made various changes or modifications to this utility model, and these equivalent form of values equally fall within the appended power of the application Sharp claim limited range.

Embodiment 1：

A kind of tea drier, as shown in figure 1, baking oven 1, hot air generator 2 is included, the hot air generator 2 Connect a heat-exchange tube 3 at air inlet 21, entangle a sleeve pipe 4 outside heat-exchange tube 3, after the bottom bending of sleeve pipe 4 is L-shaped It is connected with the air vent 11 of baking oven 1, the position of the bending of sleeve pipe 4 is less than the air vent 11 of baking oven 1, and the two ends of heat-exchange tube 3 are worn Go out the side wall of sleeve pipe 4 and be weldingly fixed on sleeve pipe 4, heat-exchange tube 3 is set to air entry 31 near the one end on 4 top of sleeve pipe, heat Exchange pipe 3 to be connected with the air inlet 21 of hot air generator 2 near one end of 4 bottom of sleeve pipe, the position of the bending of sleeve pipe 4 is provided with One discharge outlet 41.The heat-exchange tube 3 is aluminum spiral condensing tube.4 outer wrapping one layer of heat preservation material of described sleeve pipe.It is described Air entry 31 arranges dust removal and filtration equipment.Temperature display devices are provided with the baking oven 1.One is placed below the discharge outlet 41 Header tank.

Start tea drier, the high-temperature gas Jing after hot air generator 2 is heated is dried to the Folium Camelliae sinensis in baking oven 1 After dry, in 11 sleeve pipe 4 of air vent at the top of Jing baking ovens 1, from 4 bottom of sleeve pipe to sleeve pipe 4 at the top of after discharge, by heat friendship Change, the cold air in the spiral condensing tube of aluminum will be flowed through and heated, the gas in the heat-exchange tube 3 after heating is entered Further heat in hot air generator 2, then be admitted in baking oven 1, so circulate.Hot and humid gas in sleeve pipe 4 is passed through The water condensed after heat exchange is collected process in entering header tank by the osculum 41 of 4 bottom of sleeve pipe.

Heat-exchange tube 3 is aluminum spiral condensing tube, and one is the heat conductivility of the heat conductivility higher than ferrum of aluminum, and two is spiral The condensation of shape further increases contact area, makes full use of the heat of the hot and humid gas after discharge, reaches to greatest extent Heat exchange.

4 outer wrapping one layer of heat preservation material of sleeve pipe, is to reduce scattering and disappearing for heat, increasing the transformation efficiency of heat；Air-breathing Mouth 31 arranges dust removal and filtration equipment, is the quality for improving drying Folium Camelliae sinensis for the quality for ensureing air.

, in order to make full use of the air exhaust waste heat of tea drier, reducing energy consumption is cost-effective for this utility model, by drying The exhaust ports of case arrange a sleeve pipe, are provided with spiral heat-exchange tube in sleeve pipe, high by using high temperature is discharged in baking oven Wet gas, preheats to flowing through the cold air in the entrance hot air generator of heat-exchange tube, makes in boiler The initial temperature of air is higher, and less energy resource consumption can make to reach standard into the gas temperature in baking oven, so may be used With reducing energy consumption, economize on resources, improve the economic benefit of tea processing factory.
