Heat pump drying controller for crop drying and control method thereof

Abstract

The invention discloses a heat pump drying controller for crop drying and a control method thereof. The heat pump drying controller for crop drying comprises a control panel and an upper computer system. The upper computer system comprises a human-computer interface and an image processing module. The three-section variable temperature cyclic drying process is adopted for a controller. After an operator selects a required drying mode on the upper computer system according to the initial conditions of crops, the controller automatically controls the drying process of materials; meanwhile, the upper computer system monitors and records the system running conditions; the controller samples images of the materials through an industrial camera in real time in the drying process and slightly adjusts the drying mode according to the processing results of the material images. The heat pump drying controller for crop drying realizes the heat pump automatic crop drying technology and can guarantee the appearance quality and the nutritive value of the dried crops; the controller is reliable in operation; the quality of the dried materials is stable; the system drying efficiency is high, energy consumption is low, manual intervention is not needed, the drying cost is lowered, no pollutant emission and no noise pollution happen in the drying process.

Description

technical field [0001] The invention relates to a heat pump controller, in particular to a heat pump drying controller for drying crops and a control method thereof. Background technique [0002] With the maturity of heat pump drying technology, tobacco leaves, herbs, etc. are dried using heat pump technology, but the current heat pump controller has the following problems: [0003] The operator needs to control the drying process based on experience, and the operator is required to respond to various problems in the drying process in a timely manner. The drying effect is greatly affected by human beings, resulting in unstable product quality and low drying efficiency. [0004] At present, crops mainly use hot air drying technology, which has imprecise temperature regulation, high energy consumption, and pollutant emissions during the drying process. Contents of the invention [0005] In order to solve the shortcomings of the above technologies, the present invention prov...
