Gas type agricultural product drying device

Abstract

The invention discloses a gas type agricultural product drying device which comprises a drying oven. The gas type agricultural product drying device further comprises a hot air generating device connected with a drying oven body through a pipeline, an air inlet channel connected with an air outlet of the hot air generating device is arranged on the bottom of the drying oven body, a plurality of drying racks are arranged in the drying oven body, trays for bearing agricultural products are transversely arranged among the drying racks, a plurality of air bellows are arranged in the drying racks, the air bellows are respectively communicated with the air inlet channel, an air outlet is formed in each air bellow in the direction facing the corresponding trays, and a moisture outlet pipeline is further formed in the top of the drying oven body. According to the gas type agricultural product drying device, hot air generated by the hot air generating device is input through the bottom of the drying oven body, and is evenly distributed to the trays through the air outlets of the air bellows, the heat of the hot air evaporates moisture of materials continually, the hot air is supplemented continually, set working temperature can be maintained accurately, moisture discharging amount is equal to water evaporated by the materials under automatic humidity control, the set optimum drying temperature can be maintained accurately, and drying quality requirements can be guaranteed.

Description

technical field [0001] The invention relates to drying equipment, in particular to a gas-fired drying device for agricultural products. Background technique [0002] At present, with the popularization and improvement of agricultural production mechanization in our country, a modern and mechanized farming pattern has emerged as the times require. Farmers no longer rely on traditional farming models, but need fast and efficient farming models. Sowing, harvesting, and storage are all It's fast paced. At present, most of the drying equipment used for crops are large-scale dryers, which have complex structures, high manufacturing costs, and difficult transportation. [0003] At present, most of the units used for heating and drying agricultural and sideline products use steam drying or direct drying using conventional coal-fired furnaces, and what's more, the natural drying method is used to process agricultural and sideline products. The above-mentioned drying processing meth...

AI Technical Summary

Problems solved by technology

The above-mentioned drying processing method has the following defects: in the drying process of agricultural products, it is necessary to manually control the drying parameters such as drying temperature, humidity and drying time, so that the drying environment in the drying equipment cannot be maintained stably. And then affect the quality of the product obtained by drying

[0004] The main internal structure of the existing dryer is a heating furnace. Due to the single structure, it will cause incomplete drying and uneven drying. If the granular crops are too wet, the particles that are not fully heated and dried will be Agglomerates fall to the bottom of the equipment, causing blockage at the outlet and affecting the normal operation of the equipment
