Airflow translation type drying room

Abstract

The utility model discloses an airflow translation type drying room which comprises a heating chamber and a material chamber, wherein heating equipment is arranged in the heating chamber; an air inlet for supplying air form the heating chamber to the material chamber and a return air inlet for returning air from the material chamber to the heating chamber are respectively formed in the left side and the right side of a partition wall between the heating chamber and the material chamber; at least one circulating fan is arranged on a hot air circulation channel between the heating chamber and the material chamber, so that a horizontal airflow movement loop is formed between the heating chamber and the material chamber, and the movement of hot airflow in the horizontal direction is very smooth. The level temperature difference and the vertical temperature difference in the drying room are effectively reduced, and materials in the drying room are uniformly heated and synchronously dried, so that the baking time is effectively shortened, and the baking energy consumption is effectively reduced. The labor input of manually stirring the materials because of non-uniform material drying during drying is avoided, while the badly-baking loss as local materials in a traditional drying room cannot be dried in time is also avoided.

Description

technical field [0001] The invention relates to a drying room for agricultural products, in particular to an airflow translational drying room, which is suitable for drying many agricultural products such as apricots, red dates, peppers, grapes, honeysuckle, peanuts, xianggu, dried eggplants, tobacco leaves, etc. processing. Background technique [0002] Fresh fruits and vegetables have high water content, strong postpartum respiratory metabolism, and are extremely perishable. Fruit and vegetable drying is an effective way to adjust supply and demand, digest seasonal surplus, and reduce postpartum rot loss. At the same time, fruit and vegetable drying can also effectively increase the additional value of agricultural products. value, increase farmers’ income, and promote local economic development. [0003] The existing fruit and vegetable drying room usually consists of two parts: a heating room and a material room. And according to the movement direction of the circulati...

Problems solved by technology

However, these two types of drying rooms require the circulating air flow to vertically penetrate the multi-layered material trays in the material room. Due to the large resistance of the air flow movement, the air flow in the drying room is unevenly distributed and the temperature difference in the vertical direction is large. , it is easy to cause the materials in the middle layer to fail to dry, and it is impossible to realize the simultaneous drying of the whole kang materials, resulting in prolonged drying time and waste of energy. Increased drying labor intensity due to artificial tumbling of materials
