Problems solved by technology

Traditional grain drying often adopts mechanical hot air drying, which has long drying time, high energy consumption, and easy pollution. After drying, the grain quality is low, and heat damage often occurs. When drying rice, it will also cause a high waist burst rate. , poor palatability, low rice yield and other shortcomings
[0003] The far-infrared radiation drying method transmits energy in the form of electromagnetic waves, which has the advantages of direct and rapid heating, clean and hygienic, energy-saving and time-saving, and small footprint, but has the disadvantages of large energy consumption and electric heating.
As a widely used traditional drying method, the hot air convection drying method uses air as the heating medium to contact the grain for heat and mass transfer. It has the advantages of uniform drying, mature technology, and extensive heat sources, but there are low drying efficiency and easy pollution. insufficient

Abstract

The invention provides a grain drying equipment, mainly comprising hot-air radiation storehouse and heat resource generator in it. Said heat resource generator comprises pulsating burner and infrared heater. The grain drying equipment in invention applies pulsating burning, infrared radiation and hot-air convection to radiate the grain in indirectly heated infrared with high temperature and shock air flow of high frequency and heat the grain by hot-air convection in combination at the same time. Compared with conventional method, the equipment is provided with low burning consumption ratio and low electric consumption ratio. It improves the speed of drying and precipitation so as to improve the drying efficiency greatly.

Description

technical field [0001] The present invention relates to a drying device, more specifically, relates to a grain drying device which adopts a pulse burner as an initial heat source and combines far-infrared radiation and convection heating. Background technique [0002] Grain drying research is an important research content in the field of agricultural product processing, and has a very broad application market and prospects. Traditional grain drying often adopts mechanical hot air drying, which has long drying time, high energy consumption, and easy pollution. After drying, the grain quality is low, and heat damage often occurs. When drying rice, it will also cause a high waist burst rate. , Poor palatability, low rice yield and other shortcomings. [0003] The far-infrared radiation drying method transmits energy in the form of electromagnetic waves, which has the advantages of direct and rapid heating, clean and hygienic, energy-saving and time-saving, and small footprint,...
