Description

A kind of hot blast tea drying box

Technical field

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

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 tealeaves typing and sludge proof purpose simultaneously, especially for flat teas tealeaves as Taiping Houkui Tea etc., its baking operation guarantees that it can finally reach flat straight and upright key especially.In actual fabrication, its tealeaves is after flattening moulding, and side is to drying and shaping in dryer; Existing drying plant preferably is wooden drawer-type baking oven, be exactly that plank is done outside framework, dry sieve and be stacked code in housing, below with carbon fire pot or electric energy baking, often there is following problem: at first, production efficiency is extremely low, because existing high-quality drying tea leaves process is still in the majority with the manual operations of bake oven type c, causes its processing and fabricating efficiency to be difficult to promote always; Secondly, the service life of tradition drying plant is low, cause often needing 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, will spend thousand yuan of 3-4 every year 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 when it manufactures efficiency the drying plant that meets demand in high service life, be that technical barrier to be solved is compeled in this area again.

Tealeaves is after tea tree picks, must can preserve for a long time through drying and processing, traditional drying and processing adopts hand-held basketwork brazier to be dried, when adopting hand-held basketwork brazier to dry, in hand-held basketwork brazier, tealeaves is heated inhomogeneous, need artificial frequent stirring, easy like this disconnected broken of tealeaves that cause, affect the quality of tealeaves, and in stirring process, the charcoal taste can penetrate in tealeaves, further affect the quality of tealeaves in the processing process of tealeaves, there are a hot-air drying process in bar shaped and curl shape Famous High-quality Tea processing later stage, the early stage of drying is the Free water volatilization stage, for 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 district, the requirement baking temperature is low, the time is long, traditional heated-air drying mode exists that hot air convective drying efficiency is low, energy consumption is large, the drawback that production efficiency is low, must seek new heat treatment method.

China Patent No.: 201110167664.3 disclose a kind of tea drying box, comprise baking oven, circulating fan, heater; Described baking oven comprises left side wall, left plate, right plate; Described circulating fan is placed in the baking oven right side; Described heater is arranged on the baking oven internal body and by driving described fan to produce on the path of air-flow; It is characterized in that: with air inlet, inner chamber form a hot air circulation the circulated air passage, be placed in the steam vent of baking oven left side wall; Described air inlet is uniform to be arranged on the right plate of casing, with circulating fan, is placed in the baking oven homonymy; Described circulation canal is placed on the interior left plate of baking oven; Described inner chamber consists of pallet and baking oven wall; This practicality is novel by the monolateral heating of design and hot air circulation, has saved a large amount of energy on the one hand, makes on the other hand shorten drying time, has improved drying efficiency.The while China Patent No.: 201110167812.1 disclose a kind of Household tea drying box, comprise casing, electric heater, blower fan, it is characterized in that: the lower left corner of described casing and the upper right corner are respectively arranged with the air inlet adapter, air outlet is taken over; On plate, a plurality of movable charging trays also are set in described casing, there is the ventilation duct of a plurality of branch wind pipes; Described air inlet is provided with electric heater in taking over; Described blower fan directly is connected on the outer end straight tube of air inlet adapter; In in described casing, plate has a plurality of heat radiation pores.A kind of Household tea drying box of this programme, in drying course, without stirring tealeaves, the tealeaves of oven dry is without distortion, without fannings, tea matter is good, simple in structure, not only send hot blast effective, and the thermal efficiency is high, and energy consumption is little, has greatly reduced cost, there is combination property preferably.
