Constant-temperature and constant-humidity unfreezing device based on Internet of Things and control method thereof

Abstract

The invention relates to a constant-temperature and constant-humidity unfreezing device based on the Internet of Things and a control method thereof. The unfreezing device comprises a heat preservation and insulation warehouse body, an electric heating system, a humidifying system, a refrigerating system, a control system and a remote control system. The device comprises two working modes, namelyan unfreezing mode and a fresh-keeping mode. In the unfreezing mode, the electric heating system and the refrigerating system are jointly controlled to achieve variable-temperature unfreezing control,the humidifying system conducts humidity control according to the set target humidity, and it is guaranteed that the unfreezing process is conducted in the constant high-humidity environment. And inthe fresh-keeping mode, the refrigerating system performs constant-temperature control. Corresponding food thawing and fresh-keeping treatment can be carried out according to different requirements, remote online parameter configuration and control can be realized, thawing parameters are greatly convenient to set and update, the quality of thawed food is guaranteed, and the economic benefit is considerable.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an Internet of Things-based constant temperature and humidity thawing device and a control method thereof. Background technique [0002] Thawing has always been a very important link in the meat food processing technology, and the quality of thawing directly affects the quality of meat. Research on thawing in my country started relatively late, but there are many studies on thawing devices, such as air thawing devices and water thawing devices. Although these thawing devices can complete the thawing preferably, there are respective shortcomings in the thawing process. The low-temperature air thawing operation is simple, but the thawing time is long, the temperature difference between inside and outside is large, the juice loss is serious, and it occupies a large area and the investment cost is high. The water thawing device is simple, the thawing speed is fast, and the wei...

Problems solved by technology

Though these thawing devices can finish thawing preferably, also there is respective shortcoming in the thawing process

Low-temperature air thawing is easy to operate, but the thawing time is long, the temperature difference between inside and outside is large, the juice loss is serious, and it occupies a large area and the investment cost is high.

The water thawing device is simple, the thawing speed is fast, and the weight loss is small, but there are disadvantages such as waste of water resources, easy loss of soluble substances in food, and easy contamination of food by microorganisms in water.
