Energy-saving grain drying system

Abstract

The invention discloses an energy-saving grain drying system, and relates to the technical field of grain drying. The drying system involves a first drying oven unit, a third drying oven unit and a second drying oven unit, wherein the first drying oven unit, the third drying oven unit and the second drying oven unit are the same and each comprises a drying oven; a first air pipe is connected between a second air outlet of the first drying oven unit and a second air inlet of the third drying oven unit; a second air pipe is connected between a second air outlet of the third drying oven unit anda second air inlet of the second drying oven unit; a third air pipe is connected between a second air outlet of the second drying oven unit and a second air inlet of the first drying oven unit; and afirst valve, a second valve and a third valve are arranged on the first air pipe, the second air pipe and the third air pipe respectively. According to the energy-saving grain drying system, through cooperative use of the three drying oven units, hot air generated by a hot air source is repeatedly and secondarily utilized while drying is facilitated, the characteristics of saving energy and beingenvironmentally friendly are achieved, and meanwhile, continuous drying is achieved, uninterrupted drying is carried out while material changing is carried out, and the drying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of grain drying, in particular to an energy-saving grain drying system. Background technique [0002] Grain drying is a key link in the process of grain production, and it is also an important part of realizing the mechanization of grain production. Due to the vigorous development of organic food and green food, new demands and challenges have been put forward for grain storage technology. "High quality, high More and more countries in the world have paid more and more attention to the green grain storage technology of high efficiency, low energy consumption and low pollution; therefore, the cooling and drying technology of grain is particularly important. Existing grain dryers mostly use a single oven, which includes a hot air inlet and a hot air outlet. When in use, the energy utilization rate of the hot air is low and energy is wasted. Contents of the invention [0003] The purpose of the present inven...
