Abstract
The invention discloses a kind of dense drying method based on the change of bulk curing barn centre leaves, the method is the baking method being changed to foundation with centre leaves, by thermometer is placed on top layer, the control of humiture is as the criterion with top layer, when observing tobacco leaf change, to observe flavescence, the drying of centre leaves, take into account the change of bottom tobacco leaf.The present invention, in bake process, as long as see that centre leaves change reaches target call, then takes into account the leaf base of bottom tobacco leaf, just can determine whether intensification or surely warm fast.Tobacco flue-curing method of the present invention is simple, has simple to operate, obviously can reduce poor sheet cigarette and pornographic movie blue veins, and increase tobacco leaf color and luster and oil content, baking quality of tobacco significantly improves.
Description
Technical field
The invention belongs to tobacco flue-curing field, particularly relate to a kind of dense drying method based on the change of bulk curing barn centre leaves.
Background technology
Within 2009, State Tobacco Monopoly Bureau has issued " bulk curing barn technical specification (trying) revised edition " (domestic cigarettes do comprehensive (2009) No. 418), file consolidation bulk curing barn construction criteria and specification, wherein have also been made the observation window of barn and explicitly call for: " on cigarette-filling house's door and insulated wall, respectively arrange a vertical observation window.Observation window on door is arranged on left-hand door, apart from lower along 900mm centre position, specification 800mm × 300mm.Observation window in insulated wall is arranged on left side apart from abutment wall 320mm, apart from 700mm position, ground, specification 1800mm × 300mm ".Observation window is mainly used in observing tobacco leaf change, to formulate or adjustment baking process, due to existing barn, can be seen the change of second layer tobacco leaf by observation window preferably, but can only see the blade tip of top layer tobacco leaf, the leaf base of bottom tobacco leaf.And existing baking technology mostly emphasizes the tobacco leaf change of heat zone (airflow descending type compression top layer) and cryosphere (airflow descending type compression bottom), tobacco grower can only infer the intensity of variation of top layer and bottom tobacco leaf by the change of second layer tobacco leaf when practical operation, easily cause error, cause baking loss.
Summary of the invention
The object of the present invention is to provide a kind of dense drying method based on the change of bulk curing barn centre leaves, the tobacco leaf change of heat zone (airflow descending type compression top layer) and cryosphere (airflow descending type compression bottom) is mostly emphasized in order to solve existing baking technology, by the observation window of existing bulk curing barn, tobacco grower can only see that the intensity of variation of top layer and bottom tobacco leaf is inferred in centre leaves change when practical operation preferably, easily cause error, cause the problem of baking loss.The present invention formulates the baking method being changed to foundation with centre leaves, thus better combines with existing barn, gives full play to the advantage of existing barn, realizes the simplification of baking process, and significantly improve baking quality of tobacco.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of dense drying method based on the change of bulk curing barn centre leaves, its special character is, the method is the baking method being changed to foundation with centre leaves, by thermometer is placed on top layer, the control of humiture is as the criterion with top layer, when observing tobacco leaf change, to observe flavescence, the drying of centre leaves, take into account the change of bottom tobacco leaf; The method is carried out according to following steps:
(1) after tobacco leaf fills a heatable brick bed, dry-bulb temperature is raised to 36 DEG C, keeps wet-bulb temperature 35 DEG C, until middle level blade tip starts to turn yellow;
(2) after middle level blade tip starts flavescence, dry-bulb temperature is raised to 38 DEG C, keeps wet-bulb temperature 36 DEG C, until more than 80% centre leaves turns yellow 8 one-tenth, the centre leaves of 1/4-1/3 starts to occur hook point simultaneously;
(3) dry-bulb temperature is raised to 42 DEG C, keep wet-bulb temperature 36-37 DEG C, until centre leaves offshoot more than 80% bleaches, blade tip all starts upper hook, occurs significantly hooking sharp crimping;
(4) dry-bulb temperature is raised to 45 DEG C, keeps wet-bulb temperature 36-37 DEG C, until the dry 3-5cm of middle level blade tip;
(5) dry-bulb temperature is raised to 48 DEG C, keep wet-bulb temperature 38 DEG C, until centre leaves master pulse all bleaches, more than 50% tobacco leaf is half-dried;
(6) dry-bulb temperature is raised to 54 DEG C, keeps wet-bulb temperature 39-40 DEG C, until centre leaves master pulse drying more than 1/3;
(7) dry-bulb temperature is raised to 60 DEG C, keeps wet-bulb temperature 40-41 DEG C, until bottom tobacco leaf master pulse more than 80% starts variable color, bottom master pulse obviously shrinks and attenuates simultaneously;
(8) dry-bulb temperature is raised to 68 DEG C, keeps wet-bulb temperature 41-42 DEG C, baking, until bottom master pulse is all dry, makes full a heatable brick bed tobacco leaf cigarette muscle dry.
Further, toasting programming rate is 1 DEG C/h.
Further, step (3), centre leaves offshoot more than 80% bleaches, and blade tip all starts upper hook, occurs significantly hooking sharp crimping, now will take into account bottom tobacco leaf, the leaf base of bottom tobacco leaf is turned yellow.
Further, in step (4), while the dry 3-5cm of middle level blade tip, take into account bottom tobacco leaf, bottom tobacco leaf is obviously fallen down, except master pulse, the whole body is yellow.
Further, in step (5), centre leaves master pulse all bleaches, and while more than 50% tobacco leaf is half-dried, takes into account bottom tobacco leaf, and bottom tobacco leaf master pulse major part is bleached.
Further, in step (6), while centre leaves master pulse drying more than 1/3, bottom tobacco leaf be made absolutely dry, and indivedual master pulse starts variable color, and bottom tobacco leaf is absolutely dry, and emphasis sees that whether leaf base 5cm is absolutely dry.
Dense drying method based on the change of bulk curing barn centre leaves provided by the invention, on the basis of existing dense drying technology, according to position and the feature of bulk curing barn observation window, good judgement can only be had to two layers of tobacco leaf when reality baking operation, by corresponding with the change of centre leaves for each stage of baking, in bake process, as long as see that centre leaves change reaches target call, take into account the leaf base of bottom tobacco leaf again, just can determine whether intensification or surely warm fast.Tobacco flue-curing method of the present invention is simple, has simple to operate, obviously can reduce poor sheet cigarette and pornographic movie blue veins, and increase tobacco leaf color and luster and oil content, baking quality of tobacco significantly improves.
