Four-layer tobacco loading bulk curing barn

Abstract

The invention discloses a four-layer tobacco loading bulk curing barn which comprises a hot air chamber and a tobacco loading chamber. Heat-partition walls are arranged between the hot air chamber and the tobacco loading chamber, the hot air chamber and the tobacco loading chamber are communicated with each other via hot air inlets and hot air return openings so that hot air flow circulation can be carried out, the four-layer tobacco loading bulk curing barn is provided with moisture removal openings connected with the external, a tobacco loading frame is arranged in the middle of the tobacco loading chamber and is provided with four layers of longitudinal beams and three upright columns, four grooves or bosses which are flush with the corresponding longitudinal beams of the tobacco loading frame are arranged on two opposite side walls of the tobacco loading chamber, one of the three upright columns is positioned at an end of one side of a curing barn door, the other two upright columns are positioned at trisection positions of the middle of the curing barn, and the other ends of the longitudinal beams are inserted into the heat-insulation walls. The four-layer tobacco loading bulk curing barn has the advantages that the tobacco loading frame is arranged by the aid of the grooves on the walls instead of being arranged on side walls of the tobacco loading chamber, the construction cost of the curing barn is greatly reduced, space occupied by existing wall leaning tobacco loading frames is vacated, tobacco hanging quantities of tobacco rods of various layers are increased, the quantity of tobacco which is loaded and cured at one step is increased by 30% at least, and the construction occupied area of the curing barn is reduced under the condition of identical tobacco loading capacity.

Description

technical field [0001] The invention relates to a four-layer smoke-intensive barn. Background technique [0002] Under the current background of large-scale agriculture, the State Tobacco Monopoly Bureau formulated the "Revised Edition of Technical Specifications for Intensive Curing Barns (Trial Implementation)" (Guoyanbanzong [2009] No. 418) to guide the construction of tobacco leaf preparation facilities across the country. The intensive curing barn has been promoted on a large scale across the country. In addition to being used for curing flue-cured tobacco leaves, it is also widely used in drying processing of vegetables, fruits, Chinese medicinal materials and fungus cultivation during idle seasons. [0003] As far as the technical specifications of the currently popularized barns are concerned, the main problems or deficiencies in the application are: first, the curing capacity is relatively low, the construction cost is relatively high, and the utilization rate of he...
