Abstract:

The research aims to design a heat load that meets the requirements of cigar tobacco leaf drying process, screen suitable heat loads for the capacity of the drying room, and lay the foundation for the construction of cigar tobacco leaf drying rooms and the development of products with independent intellectual property rights. Building Simulation Analysis Software (DEST) was used to simulate and predict the thermal load of the enclosure structure of the drying room during the drying season. Based on the predicted results, the corresponding power was selected to verify the cigar and tobacco leaf drying. The validation results of air drying showed that the total heat load of the air drying room was the sum of the heat loss of the maintenance structure of the air drying room and the heat loss of the air drying room's dehumidification. The maximum value of the total heat load was 13.39 kW. The average heat load per kilogram of fresh tobacco leaves is 13.39 w / kg, which can be used for the heat load of cigar drying room under the condition of tobacco loading.

Key words: cigar, air room, heat load, heat source, tobacco loading
