Abstract

The invention relates to a device and method for drying agricultural products. The method comprises the following steps of carrying out stage drying by using microwave energy of a microwave drying mechanism and thermal energy of a thermal energy drying mechanism, and using a vibrating mechanism to allow a material to be in a uniform fluidized state in the drying process. The microwave drying mechanism is respectively provided with first microwave power, second microwave power and third microwave power, and the thermal energy drying mechanism is respectively provided with a first drying temperature, a second drying temperature, a third drying temperature and a fourth drying temperature; a vibrating motor of the vibrating mechanism is respectively provided with a first vibration frequency, a second vibration frequency, a third vibration frequency and a fourth vibration frequency. The device comprises a rack, the microwave drying mechanism, the thermal energy drying mechanism and a material pallet which are arranged on the rack, and also comprises the vibrating mechanism, wherein the material pallet is arranged relative to the microwave drying mechanism and the thermal energy drying mechanism. According to the device and the method provided by the invention, the utilization rate of thermal energy and microwave energy is improved, the drying energy consumption is reduced, the uniformity of microwave drying is effectively improved, and the quality of products is improved.

Description

technical field [0001] The invention relates to an agricultural product processing and drying device and method, in particular to an agricultural product drying device and method that adopts vibratory fluidized drying and microwave and thermal energy to dry fruits and vegetables in sections. Background technique [0002] Microwave drying uses microwave radiation energy to heat the medium of the material as a whole. It has fast drying speed, high efficiency and low energy consumption, and has strong technical advantages. my country's atmospheric pressure microwave drying technology and equipment are also widely used in chemical industry, light industry, medical treatment and agricultural product processing, and are most widely used in chemical and medical industries. However, the uniformity of microwave drying is poor, and it is easy to cause coking at the edge or sharp corner of the material due to overheating, product surface hardening and internal gelatinization, etc., res...
