Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0022] The following combination figure 1 , figure 2 , image 3 To illustrate: the device can realize the functions of fruit and vegetable cleaning, hot soaking, hot water spraying, intermittent heat treatment, etc. at the same time.
[0023] Cleaning: Turn off the air source heat pump system 1, open the shut-off valves 12 and 14, and send tap water through the tap water tank 11 from the bottom of the box body. The clear water is fully oscillated, and the fruits and vegetables moving up and down are in full contact with the oscillating clear water, which improves the cleaning rate and reduces the later incidence of fruits and vegetables;
[0024] Thermal spraying: turn on the air source heat pump system 1, the thermostatic valve 9, the shut-off valves 17 and 27, the air s...

Description
technical field [0001] The invention relates to a multifunctional air source heat pump fruit and vegetable heat treatment device, which belongs to the field of agricultural and forestry product processing. Background technique [0002] As the public pays more attention to the quality of fruits and vegetables, it is necessary to study the heat treatment and preservation technology of harvested fruits and vegetables in depth, improve the quality of refrigeration, and prolong the shelf life of fruits and vegetables. However, many heat treatment equipments now use electric heating. Complicated, each process requires its own equipment, which increases the initial equipment investment and later electric energy, labor investment, etc., combined with the advocacy concept of high, low energy consumption and high efficiency, a multifunctional air source heat pump fruit and vegetable heat treatment device is proposed. Combining energy-saving air source heat pump and fruit and vegetable...
