Vibration type multifunctional combined drying device capable of automatically controlling temperature and humidity

Abstract

The invention relates to a fruit and vegetable material drying device, in particular to a vibration type multifunctional combined drying device capable of automatically controlling temperature and humidity. The device is composed of a control device, an infrared thermometer, a weighing sensor, a weighing frame, an optical fiber thermometer, a computer, a hot air heating device, a microwave magnetron, a drying cavity, a material tray, a vibration device, a rotating device, a vacuum pump, an observation window, a drying cavity door, an electromagnetic valve, an illuminating lamp and the like. In the drying process, movement of the materials is regulated and controlled through the vibration device and rotating equipment, hot air drying can be coupled with microwave drying under the non-vacuum condition, the heat and mass transfer directions of the materials can be consistent, hot spots of the materials are avoided, and the purpose of uniform and rapid drying is achieved. Through an automatic temperature and humidity control device, the internal temperature of the materials is monitored in real time, overheating damage of the materials is avoided, meanwhile, the real-time water content of the materials is tracked, and the drying end point is judged. According to the device, the flexibility of equipment is remarkably improved, materials are vibrated and rotated under the conditions of microwave vacuum drying and microwave coupling hot air, the purpose of efficient and uniform drying is achieved, the quality of dried products is effectively improved, energy consumption is remarkably reduced, and the production cost is reduced.

Description

Technical field [0001] The present invention relates to a fruit and vegetable product drying apparatus, particularly an automatic temperature-controlled vibrating multifunctional combined drying device. Background technique [0002] Fruits and vegetables are the main source of human body necessary dietary nutrients (vitamins, minerals, dietary fibers, etc.), which possess a very important position in modern balanced diet. Drying as one of the most common machining units in the field of fruit and vegetable processing, is the main purpose to suppress the growth and reproduction of the material and the growth of the microorganism, extend the product shelf period, increase the product appliance, and increase the product add-on. Balanced market supply and demand relationship. The cooling product is high, but the cost is high, and the dry production capacity is limited. Traditional hot air drying due to surface temperature overheating and drying time, the sample is prone to browning, t...
