Description

Air flow interactive intelligent curing barn

Technical Field

The utility model relates to the technical field of baking equipment, in particular to an air flow interactive intelligent baking room.

Background

The air flow interactive curing barn is an important device in the drying process, and improves the drying efficiency and uniformity of materials by controlling the flow mode of air flow. According to the movement direction of the air flow, the common air flow interactive baking houses are mainly divided into two types of air flow rising type and air flow falling type.

The design of the air-rising type curing barn enables hot air to flow from bottom to top, and heat is transferred to materials when the hot air passes through the material layers, so that a drying effect is achieved. This design takes advantage of the natural flow characteristics of hot air, since the hot air density is less than cold air, which naturally rises. However, this also means that in a curing barn, the air temperature gradually decreases from the bottom to the top, resulting in uneven temperature field for drying the material, the material at the bottom may be overdried due to higher temperature, and the material at the top may be underdried due to lower temperature.

The airflow descending type curing barn is opposite to the airflow ascending type, and the design of the airflow descending type curing barn enables hot air to flow downwards from top to bottom. The advantage of this design is that the effect of gravity can be used to make the hot air more evenly cover the whole material layer, which theoretically helps to improve the uniformity of material drying. However, in actual operation, due to the natural rising trend of the hot air, even in the airflow-descending type baking room, a certain temperature gradient can occur, namely, the temperature gradually rises from the top to the bottom, and the uniformity of material drying is also affected.

Whether the air flow is in an ascending type or in a descending type, as the air flow is in unidirectional circulation, obvious temperature gradient exists in the curing barn, and further the uniformity and the efficiency of material drying are affected.
