Solar air source heat pump device used for vegetable and fruit drying

Abstract

The invention relates to a solar air source heat pump device used for vegetable and fruit drying. The solar air source heat pump device is mainly used for solving the drying problem of various kinds of farm products. Drying equipment mainly comprises a solar air source heat pump system, a machine frame, a drying chamber, a material feeding device, a material discharging device, a lifting device and object carrying plates, wherein the object carrying plates are arranged in the drying chamber, and in addition, the material feeding device, the lifting device and the material discharging device are positioned on the machine frame. The solar air source heat pump system provides heat sources for the drying equipment, the energy is saved, the consumption is reduced, and in addition, the pollution is avoided. The lifting device is mainly used for lifting the object carrying plates, the material discharging device can conveniently and smoothly push out the firstly dried object carrying plates. 15 layers of object carrying plates are placed in the drying chamber, the object carrying plates are overlapped, the hot air utilization rate is improved, and the drying time and the air drying field of farm products are reduced. Under the effects of the material feeding device, the material discharging device, the lifting device and the solar air source heat pump system, the equipment can realize the automatic material discharging, the automatic material feeding and the temperature regulation operation, the work time and the labor resources are saved, and the production efficiency and the energy source utilization rate are improved. The solar air source heat pump device has the advantages that the structure is simple, the operation is convenient, and the automation and flow line operation is convenient.

Description

technical field [0001] The invention relates to a drying device, in particular to a vegetable solar energy-air source heat pump dryer. Background technique [0002] It is not only difficult to preserve fresh agricultural and aquatic products for a long time, but also deteriorates or rots, and is unhygienic. Nowadays, people mostly use vacuum packaging for convenience and sanitation, freshness preservation, storage and transportation. Before packing, it is necessary to clean the stains on the surface of the product with water, and then dry it naturally, but the drying process takes a long time, the productivity is low, and a large amount of drying places are needed. This process will also cause secondary pollution. At the same time, some drying equipment still uses coal, oil and other fuels and electricity as energy sources for generating heat energy, which cannot meet the requirements of energy saving and environmental protection. In order to solve these existing problems ...
