Intelligent low-temperature baking device and baking method thereof

Abstract

The invention discloses an intelligent low-temperature baking device and a baking method thereof. The intelligent low-temperature baking device comprises a burning machine; an internal circulation heat exchange device and a baking device are separately arranged on one side of the burning machine; and a weight sensor which can weigh a material to be dried is mounted in the baking device. The devicecan automatically control the water content of the material within a specified range by automatically sensing the weight of the material through the weight sensor and manually setting a drying rate;the baking situation does not need to be observed repeatedly; intelligent baking is realized in the whole process; the requirements of people can be met better; two types of heat recycling structuresare designed in a device through an ingenious design; compared with the conventional heat exchange device, the structure is simpler; the energy utilization rate is improved above 95 percent; and the scheme disclosed by the application is applicable to baking various types of agricultural and sideline products and traditional Chinese medicinal materials, is suitable for small-batch baking, can alsomeet the requirement of large-scale production, and is wide is application range.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to an intelligent low-temperature baking device and a baking method thereof. Background technique [0002] With the improvement of people's living standards, more and more people like agricultural and sideline products. The production of dry agricultural and sideline products is inseparable from the drying process. Since agricultural and sideline products contain a lot of water, the drying process of agricultural and sideline products will last for a long time. For a long time, in order to speed up the drying of agricultural and sideline products and improve production efficiency, some crops are generally dried by manually exposing the crops to the sun or drying them in a drying room. Since the heat energy directly radiates to the crops, the crops are heated Uneven, large dust pollution, long dehydration time of crops. [0003] In view of this, the Chinese invention patent...

AI Technical Summary

Problems solved by technology

However, the existing drying settings also have the following problems in specific use: (1) The existing drying room does not have the effect of intelligent drying at all. Before drying, in order to know the weight of the material, it is necessary to put the material Weigh the material by weighing, and then put it into the drying room for baking, and when drying, the only way to judge the degree of drying of the material is to observe the material repeatedly with the naked eye, and because the human eye will also have a certain degree of drying. The error makes the degree of material drying will also have certain errors, the product quality cannot be guaranteed, and manual repeated observation is required, which will also consume more labor costs; (2) Some of the existing drying equipment uses combustion Drying machine for drying, and some use gas for drying. When drying, the high-temperature flue gas after combustion is directly passed into the drying room for baking, that is to say, the flue gas will directly contact with the material. Due to the flue gas Contains a large amount of granular dust and toxic fumes, which will pollute the materials to be dried and affect the quality of the materials; (3) The residual heat in the flue gas cannot be effectively recovered during the baking process, and the energy utilization rate is low
