A curing module is provided of generally rectangular solid configuration of which the bottom is imperforate and includes runners to facilitate lifting by fork lift; the top is imperforate with means for minimizing air leakage between the tobacco and top inner surface; the rear wall is imperforate with horizontal ledges to support the ends of tines which penetrate the tobacco; the front is generally imperforate, but opens to facilitate loading and when closed enables insertion of sharp rods which penetrate the tobacco and provide vertical support; and two opposed perforate side walls which permit horizontal cross-flow of the curing gas. One wall of which may be hinged to permit mechanized unloading of the cured leaf. Also provided is a simplified curing structure to receive the modules which are stacked by conventional fork lift equipment and to direct curing air horizontally through the perforate sides of the modules at controlled temperature, himidity and velocity.

Significant amounts of heat energy, otherwise wasted in the curing and drying systems previously known, are recovered and recycled in the multi-chamber system of the present invention to thereby significantly increase efficiency and reduce fuel requirements. Tobacco or other moisture containing material is cured and dried in batches in a plurality of individual chambers, with each chamber having suitable controls for individually controlling the temperature and humidity conditions of the curing air which is circulated through the chamber. Means and methods are disclosed for recovering and recycling the heat content of the heated exhaust air from the respective chambers, for using solar energy for further heating the air, and for recovering and recycling the heat energy of the batch of material as it is cooled down at the end of the curing and drying cycle.

A tobacco handling and curing system and method is provided and in one aspect includes a curing container of generally rectangular solid configuration of which four side walls are generally imperforate and a pair of opposed side walls are perforate for the passage of curing gas therethrough. Such container may include one or more perforate interior transverse walls parallel to the opposed walls; adjustable edge baffles for the perforate side walls; and means carried by a pair of imperforate side walls to assist in handling the container. In another aspect of the present invention, novel curing mechanism is provided to receive a plurality of the containers and to direct gas therethrough at predeterminable temperature, humidity and volume.
