Abstract

The utility model discloses a multi-box hot air tea drying device, which structurally includes a pumping pipeline, tea sieves, outer box bodies, hot air pipelines, a hot air supply pipeline, a resistive heater, an exhaust fan and an air inlet pipe, wherein the side walls of the four outer box bodies are connected with the pumping pipeline; the hot air pipelines are arranged on the outer walls of the outer box bodies; the hot air pipelines are mutually communicated and are communicated with the pumping pipeline and the hot air supply pipeline; the hot air supply pipeline at the bottoms of the outer box bodies is connected with the resistive heater; the air inlet pipe is arranged at the lower end of the resistive heater; outdoor air enters the resistive heater through the air inlet pipe, and is heated to a corresponding temperature; the tea sieves are arranged inside the outer box bodies; through holes are formed in the tea sieves. According to the utility model, the design of double box bodies greatly improves the efficiency in tea processing; besides, the heating mode that hot air is extracted is adopted to keep the hot air inside the box bodies to be at a certain temperature and dryness, therefore, the multi-box hot air tea drying device has greater popularization value.

Description

Many casings hot blast tea drying device

Technical field

The utility model relates to a kind of machine for processing tea, relates in particular to many casings hot blast tea drying device.

Background technology

Oven dry is the important procedure that tealeaves is made, its main purpose is place to go tealeaves all moisture content inside and outside, reach simultaneously tealeaves typing and sludge proof purpose, for flat teas tealeaves such as Taiping Houkui Tea etc., its baking operation guarantees that especially it can finally reach flat straight and upright key especially.In the actual fabrication, its tealeaves after flattening moulding, side's drying and shaping to the dryer; Existing preferably drying plant is wooden drawer-type baking oven, be exactly that plank is done outside framework, the baking sieve is stacked code in housing, the below toasts with carbon fire pot or electric energy, often there is following problem: at first, production efficiency is extremely low, because existing high-quality drying tea leaves process hand-manipulated in the majority with bake oven type c still causes its processing and fabricating efficient to be difficult to lifting always; Secondly, the service life of tradition drying plant is low, often needing to cause safeguarding and change, loss is high, if calculate with ten thousand family tea growers, will cut down more than 10,000 cube of timber every year, ruin nearly thousand mu of mountain forests, and will spend thousand yuan of 3-4 every year and be used for changing and maintenance of equipment, but destroy ecological resources when developing the economy; How developing a kind of quality requirements that both can guarantee the tealeaves finished product, can improving the drying plant that satisfies demand in high service life when it manufactures efficient, be that technical barrier to be solved is compeled in this area again.

After tealeaves picks from tea tree, must can preserve for a long time through drying and processing, traditional drying and processing adopts hand-held basketwork brazier to dry, when adopting the hand-held basketwork brazier oven dry, tealeaves is heated inhomogeneous in the hand-held basketwork brazier, need artificial frequent stirring, easy like this disconnected broken of tealeaves that cause affects the quality of tealeaves, and in stirring process, the charcoal taste can penetrate in the tealeaves, the quality that further affects tealeaves is in the processing process of tealeaves, and there are a hot-air drying process in bar shaped and curl shape Famous High-quality Tea processing later stage, and the early stage of drying is the Free water volatilization stage, be permanent rate dehydration, drying efficiency is higher; And the later stage is the constitution water volatilization stage, the tealeaves moisture content is down to 5% from 15%, constitution water need to overcome the resistance that hydrone turns the district, the requirement baking temperature is low, the time is long, traditional heated-air drying mode exists that hot air convective drying efficient is low, energy consumption is large, the drawback that production efficiency is low must be sought new heat treatment method.

Summary of the invention

Deficiency for existing tea drying device exists the utility model proposes many casings hot blast tea drying device.

The utility model adopts following technical scheme to solve existing issue.

Many casings hot blast tea drying device, its structure comprises: pump-line, tealeaves sieve, outer case, hot air duct, hot blast feeding pipeline, resistance heater, air exhauster, air inlet pipe.

Described outer case has four, and the structure of four outer case is in full accord, and the sidewall of two outer case is connected with pump-line.

The outer wall of described outer case is provided with hot air duct, hot air duct be interconnected and with pump-line and hot blast feeding pipeline communication.

The hot blast feeding pipeline of described outer case bottom is connected with resistance heater, and the lower end of resistance heater is provided with air inlet pipe, and outside air enters into resistance heater through air inlet pipe and is heated to corresponding temperature.

The inside of described outer case is provided with the tealeaves sieve, is provided with emptying aperture on the tealeaves sieve, makes things convenient for the circulation of hot blast, simultaneously, is of value to the oven dry of tealeaves.

The beneficial effects of the utility model: the many casings hot blast tea drying device that the utility model proposes, the design of the two casings of employing has improved the efficient of Tea Processing greatly, adopt simultaneously the heat-supplying mode of hot blast pull-out type, so that the hot blast in the casing keeps certain temperature and drying.Of the present utility model simple in structure, with low cost, can be used for the oven dry of tealeaves, therefore, have larger promotional value.
