AI Technical Summary

Technical Problem

Existing liquid classification drying equipment suffers from low drying efficiency and low temperature control accuracy, making it impossible to accurately adjust the temperature according to the characteristics of the material at different drying stages, thus affecting the quality of the final product.

Method used

A stepped drying table was designed, including first, second, and third drying plates with progressively increasing inclination angles. It is equipped with an electric heating film and a temperature sensor, and precise temperature control is achieved through a PLC controller. Combined with a Teflon non-stick coating, it reduces material flow resistance.

Benefits of technology

It improves drying efficiency, ensures that materials are under optimal drying conditions at each stage, avoids local overheating or insufficient temperature, and guarantees the quality stability of the final product.

Abstract

This utility model discloses a liquid grading drying device, including a shell, inside which is arranged a stepped drying platform. The stepped drying platform consists of a first drying plate, a second drying plate, and a third drying plate with progressively increasing inclination angles. The first, second, and third drying plates are distributed in a step-like manner from high to low. This liquid grading drying device, with its stepped drying platform and progressively increasing inclination angles and reasonably set lengths for the first, second, and third drying plates, adapts to the changes in material flowability at different drying stages, ensuring sufficient drying time and improving drying efficiency. Simultaneously, through the cooperation of a temperature sensor and a PLC controller in the heating assembly, the temperature of each drying plate can be precisely controlled, avoiding local overheating or insufficient temperature, solving the problem of low temperature control accuracy, and ensuring the quality of the final product.
