AI Technical Summary

Technical Problem

Existing circulating grain dryers require multiple lifting and repeated drying of grains, resulting in energy waste.

Method used

Design a continuous grain drying equipment, including a box and a heating mechanism. The box is provided with a grain storage section, a drying tempering section and a cooling section from top to bottom. The drying tempering section includes multiple drying tempering zones arranged vertically. Each drying zone is provided with an independent heating branch pipe and an inlet and outlet air guide assembly. The material falls by its own gravity and passes through multiple drying zones and tempering zones in sequence for drying.

Benefits of technology

This method enables multiple drying and tempering of materials during a single drying process, avoiding energy waste, improving drying efficiency, and reducing costs.

Abstract

This invention discloses a continuous grain drying device, comprising a housing and a heating mechanism. The housing, from top to bottom, includes a grain storage section, a drying and tempering section, a cooling section, and a grain discharge section. The top of the grain storage section has a drying inlet, and the bottom of the grain discharge section has a drying outlet. The drying and tempering section includes multiple drying and tempering zones arranged vertically, each zone comprising a drying zone and a tempering zone. Each drying zone is equipped with an air inlet guide assembly and an air outlet guide assembly. The heating mechanism includes a heating main unit, a main heating pipe, and branch heating pipes. The hot air inlet of the main heating pipe is connected to the heating main unit. The air outlet of the branch heating pipe is connected to the air inlet guide assembly of the corresponding drying zone, and the air inlet of the branch heating pipe is connected to the hot air outlet of the corresponding main heating pipe. This continuous grain drying device solves the technical problem of existing circulating dryers, which require multiple lifting and circulating of grain for drying, easily leading to energy waste.
