Embodiment 1

[0064] In this embodiment, a control method for a heat pump tobacco dryer is provided, such as figure 1 shown, including:

[0065] S1. Obtain the actual temperature of the baking room, control the operating frequency of the compressor according to the difference between the set temperature and the actual temperature of the baking room, and gradually increase the temperature rise rate of the baking room by controlling the operating frequency of the compressor, so that the temperature of the baking room reaches target temperature range.

[0066] In step S1, the operating frequency of the compressor is controlled according to the difference between the set temperature of the baking room and the actual temperature, and the temperature rise rate of the baking room is increased in stages by controlling the operating frequency of the compressor, so that the temperature of the baking room can reach the target temperature range smoothly. include:

[0067] According to the obtained ac...

Embodiment 2

[0121] This embodiment provides a heat pump tobacco dryer, including a storage medium and a processor, the storage medium is a non-transitory computer-readable storage medium for storing computer programs, and the processor is used for calling the A computer program in the storage medium, when the computer program runs, executes the control method in Embodiment 1 as an example.

Abstract

The invention discloses a heat pump type tobacco dryer and a control method thereof, which are used for solving the problems that tobacco leaves crack and the baking effect is not ideal due to the fact that the temperature rise of the dryer is too fast. The control method of the heat pump type tobacco dryer comprises the steps that the actual temperature of a curing barn is obtained, the operation frequency of a compressor is controlled according to the difference value of the set temperature and the actual temperature of the curing barn, the temperature rise rate of the curing barn is increased in a staged mode by controlling the operation frequency of the compressor, and the temperature of the curing barn reaches a target temperature interval. The temperature rise rate of the curing barn is increased in stages, operation of the compressor is controlled through different strategies according to the current curing barn dry-bulb temperature average value and the preset curing barn temperature critical value, the temperature rise speed of the curing barn can be prevented from being too high, and the curing barn is prevented from being too hot in the temperature drying stage.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a heat pump tobacco dryer and a control method thereof. Background technique [0002] The cultivation and production of flue-cured tobacco in my country started from 1910 to 1915. In the past 100 years, the barn equipment has gradually formed a structural form suitable for my country's rural economic and technological conditions from low-level to high-level, from simple to complex. Before the 1950s, our country has been using the simple and crude soil baking room, and the fire is directly heated in the baking room. In the 1960s, with the popularization and use of flue-cured tobacco dry and wet thermometers, the curing technology was improved, but the curing process was still based on experience. After entering the 1970s, the baking process aimed to pursue yellow, fresh and clean, and adopted the operation technology of "high temperature and fast roasting". From the mid-to-late ...
