Abstract

A roaster for roasting coptis comprises a feed inlet, a feed outlet, an air outlet, a furnace tank communicating a flame path in its bottom, a roasting chamber, a rotary roast cage disposed inside the roasting chamber, a double-path suspending flue disposed below the rotary roast cage and communicated with the flame path. The harvested rhizomes of coptis are fed through the feed inlet into the rotary roast cage, and the air in the roasting chamber is heated by flame that is produced by the furnace tank and passes through the flame path and double-path suspending flue. The rotary roast cage is rotated and the water in the rhizomes of coptis is evaporated by the hot air and discharged from the suction holes. The rotary roast cage is rotated counterclockwise and the dried rhizomes of coptis are discharged from the feed outlet. This roaster avoids the roast directly with open fire, and the toast temperature is homogeneous, which ensures short roast time, high yield; and low labor intensity since frequent manual turnover is not required. During the roasting process, mud and sand are screened out of holes in the wall of rotary roast cage, ensuring quality of roasting. It takes about 5 hours to finish one roasting process.

Description

A kind of oven that toasts the coptis

Technical field

The utility model relates to a kind of oven that toasts the coptis.

Background technology

The coptis is a conventional Chinese medicine, in the Shennong's Herbal of Han dynasty, just classify as top grade. be the Mao Tuke herbaceos perennial, having multiple pharmacological effect such as antibiotic, anti-inflammatory, Hangzhoupro protozoon, antiviral, anti-radiation, detoxifcation, step-down, cholagogic, enhancing immunity function, is one of important conventional medicament of using always of middle herbalist.

Coptis artificial growth history is very long in China, though plantation history is very long, but the still more original backwardness of its baking process, the drying processing method of the coptis, " the drying processing method of the coptis " [friend of farmers' as Zou Jiuan, 2004 (2): 46] with " the drying processing method of the rare traditional Chinese medicine coptis " [rural area practical technique and information, 2004 (4): 50-51], introduced in two literary compositions with a kind of representational Coptic root baking method, the coptis rhizome that is about to excavate places in a heatable brick bed sieve, timber with the frame of scaffolding dismantling is done fuel, and in the igniting heating of vent place, pyrotechnics enters a heatable brick bed sieve by quirk a heatable brick bed sieve coptis is toasted.Also have " a kind of rotary food baking machine " (patent No. 02243734), it comprises frame, transmission mechanism, heater, circular bake plate and circular orbit and shell, loam cake.Transmission mechanism converts the high speed rotary motion of motor to the low-speed rotation of bake plate, below circular bake plate, be provided with rectangle combined type Honey-comb briquet stove, the faint flue dust that produces during the honeycomb briquette burning, concentrate discharger and outdoor by the flue dust that is provided with on the stove and accessory, provide infra-red radiation heat energy simultaneously to circular bake plate with the outdoor thin chimney discharge that communicates.

The tradition baking method yields poorly, and every stove once can only toast tens kilograms of coptiss; Need ceaselessly to grab son with iron during the baking and stir, beat, labour intensity is big; This method is directly with naked light baking, and firepower is difficult to control, makes medicinal material uneven and roasting paste of being heated, and the pernicious gas that is produced in the combustion process might be absorbed by medicinal material, directly influences product quality.A kind of rotary food baking machine only is used for roasting food.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aim to provide a kind of rational in infrastructure, use light and flexible, easy to operate a kind of oven that toasts the coptis.

The implementation of the utility model purpose is, a kind of oven that toasts the coptis, body of heater one end has charging aperture 10, discharging opening 12, and there is chimney 4 at the top, has the bleeding point of air exhauster 7, under breast hole 15 is arranged, burner hearth 18 usefulness fire bars 17 are separated by with ventilating duct 19, and there is rotary baking cage 5 in baking vessel 8, and the cage wall has sieve aperture, in have and stir tooth bar 9, the cage axle 11 of rotary baking cage 5 connects reducing motor 2, and rotary baking cage has double hanging type flue 16 for 5 times, and double hanging type flue 16 communicates with quirk 14.

When using the utility model, the coptis rhizome of excavating is back put into rotary baking cage 5 from charging aperture 10, at burner hearth 18 internal combustion faggot or coals, flame process quirk 14 and double hanging type flue 16 are with the air heat of baking vessel, and the rotary baking cage clockwise direction rotates, and hot gas comes out the water evaporates in the coptis rhizome, the steam of evaporation is discharged by aspirating hole, after the coptis rhizome drying, be rotated counterclockwise rotary baking cage, the coptis is drawn off automatically by the discharging opening 12 of oven bottom.

The utility model compared with prior art has the following advantages and characteristics:

1, because of rotary baking cage is arranged, and ceaselessly evenly rotate, the coptis is evenly stirred in bake process, be heated evenly unanimity, avoided that the traditional handicraft local temperature is too high is stuck with paste burned by baking or local temperature is crossed low dry not saturating phenomenon and taken place, silt sifts out from the cage wall sieve aperture of rotary baking cage in the dry run, has guaranteed product quality;

2, every stove once can toast the coptis more than 200 kilograms, and the efficient height has improved several times than traditional handicraft;

3, the heat conduction is fast and even, good heat preservation performance, energy utilization rate height;

4, need not manually stir in the bake process, labour intensity is low.

The specific embodiment

Body of heater of the present utility model has charging aperture 10, discharging opening 12, chimney 4, bleeding point 7, breast hole 15, burner hearth 18 usefulness fire bars 17 are separated by with ventilating duct 19, there is rotary baking cage 5 in baking vessel 8, and there is double hanging type flue 16 the rotary baking cage below, and double hanging type flue communicates with quirk 14.

With reference to Fig. 1, the bearing 3 that links to each other with reducing motor 2 is supported by bracing frame 1, and the cage wall of rotary baking cage 5 is supported by interior support 6, and there is the ventilating duct 19 that communicates with burner hearth 18 on ground 13.

When using the utility model, the coptis rhizome of excavating is put into rotary baking cage 5 from charging aperture 10, at burner hearth 18 internal combustion faggot or coals, flame process quirk 14 and double hanging type flue 16 are with the air heat of baking vessel, and hot-air toasts the coptis, bake process divides two stages, phase I, 85-90 ℃ of control temperature is incubated 3-4 hour, 80-85 ℃ of second stage control temperature is incubated 1-2 hour.In bake process, turn clockwise by reducing motor driven rotary formula baking cage, hot gas comes out the water evaporates in the coptis rhizome, and the steam of evaporation is extracted out from aspirating hole by the air exhauster of being adorned on the aspirating hole 7.After the coptis drying, be rotated counterclockwise by reducing motor driven rotary formula baking cage, the coptis is drawn off automatically by the discharging opening 12 of oven bottom.When rotary baking cage rotated, the silt that drops from the coptis sifted out from the sieve aperture of cage wall, makes the coptis remove silt simultaneously in dry run, has guaranteed product quality.
