Static electricity and dry-air blast combined drying device

Abstract

The invention relates to the technical field of food drying, in particular to a static electricity and dry-air blast combined drying device. The device of the invention comprises a drying oven, a drying device, a placing device and a filtering device. The right side of the drying oven is provided with the drying device. The drying device includes a connecting pipe, an outlet pipe, a heat pump, aninlet pipe, a fixed rod, a fan, a humidity sensor, a one-way valve, a high-voltage electrostatic electricity generating pipe, a gas pipe, a fixed box, a first box cover, an air duct, a drying filter screen and an electronic control valve. The connecting pipe is communicated with the top end of the right end face of the drying oven. In the invention, through the high-voltage electrostatic electricity generating pipe and the fan, This arrangement is matched with ozone generated after the high-voltage electrostatic electricity generating pipe generates an electric field, traction of the air by the fan, heating of the air by the heat pump and communication between the connecting pipe and the drying oven, the product can be sterilized and evenly evaporated at a lower temperature when a productwith less moisture is dried. Therefore, the drying time is greatly shortened, and the equipment has advantages of low manufacture cost, environmental protection and energy conservation.

Description

technical field [0001] The invention relates to the technical field of food drying, in particular to a drying device combining static electricity and dry air. Background technique [0002] Food drying is mainly to remove the moisture in food, so as to facilitate the storage of food and prolong the storage time of food. With the continuous progress and development of society, there are more and more methods of food drying, and more and more food drying equipment. More and more, with the continuous increase of food drying equipment, some food drying methods and drying equipment will have some defects when drying food. Therefore, there is an increasing demand for a drying device that combines electrostatic and dry air. [0003] In the field of food drying, the traditional hot air method will cause heat damage to vegetables when drying food with all their heart, seriously affecting food texture, color, aroma components and nutritional value.

Problems solved by technology

[0003] In the field of food drying, the traditional hot air method will cause heat damage to vegetables when drying food with all their heart, seriously affecting food texture, color, aroma components and nutritional value. Traditional drying technology requires high temperature, which is easy to deform, age and lose flavor. , so that the active ingredients of health food and functional food are lost, they cannot be sterilized, the drying time is long, the drying energy consumption is large, and some drying equipment is not convenient for food placement during use, and it is easy to cause incomplete drying of food when placed, and there is Some drying equipment cannot filter the drying gas, because a large amount of external air will enter the equipment when the dried food is placed, and the quality of the dried food will be reduced if the gas is not filtered. Therefore, a combination of electrostatic and dry air drying is proposed to solve the above problems. device
