Abstract

The invention discloses a tobacco dryer and a control method for electric heating of the tobacco dryer, and the tobacco dryer comprises an indoor unit which comprises an indoor heat exchanger workingas a condenser; an outdoor unit including a compressor and an outdoor heat exchanger operating as an evaporator; an indoor temperature sensor which is used for detecting the indoor environment temperature; an outdoor temperature sensor which is used for detecting the outdoor environment temperature; a PTC electric heating module which is arranged on the indoor unit and used for heating the dryingchamber; a controller which is configured to determine mode required heat corresponding to the operation mode of the tobacco dryer according to the first temperature difference value and the second temperature difference value; determining heat required by tobacco drying according to the tobacco absorption heat and the mode required heat; and controlling the compressor and the PTC electric heatingmodule to be started on the basis of the heat required by tobacco drying, so that the phenomenon that the compressor is frequently started and stopped is reduced, and the service life of the compressor is guaranteed.

Description

technical field [0001] The present application relates to the field of tobacco drying, and more specifically, to a tobacco dryer and a method for controlling electric heating of the tobacco dryer. Background technique [0002] Nowadays, many people have the habit of smoking. To become the last cigarette purchased by consumers, tobacco needs to go through many processes. Among them, tobacco drying is an indispensable process in the tobacco production process. [0003] The current air source heat pump dryers all use fixed-frequency compressors. When the drying room needs to be heated, the compressor will start heating with a fixed power after it is turned on, and the drying room will soon reach the target temperature. At this time, the compression The machine is turned off, and when the temperature in the oven drops to a certain temperature, the compressor is turned on again for heating, and the cycle is like this. When the amount of dehumidification is particularly large, th...
