Macadimia nut drying device with weighing devices and macadimia nut drying method

Abstract

The invention discloses a macadimia nut drying device with weighing devices and a macadimia nut drying method. The macadimia nut drying device comprises a barrel-shaped drying bin, the bottom of the drying bin is arranged as an air compartment, and a guide plate is arranged in the air compartment. An air inlet fan is arranged to be connected with the air compartment, an inner chamber of the drying bin serves as a drying room, the inner wall of the drying bin is provided with a sampling hole, a feeding port is formed in the top of the drying bin, and a discharging port is formed in one side of the bottom of the drying bin. The macadimia nut drying device is characterized in that the sidewall of the drying bin is provided with a moisture-removing ventilation opening which is connected with the air inlet fan through an air return pipe, a dehumidifier and a moisture-removing valve are arranged on one side of the air return pipe additionally, an air inlet valve is arranged at the joint between the air inlet fan and the air return pipe, a display device, a temperature probe and a humidity probe are arranged on the sidewall of the drying bin, vertical air supply pipes are arranged on the bottom surface of the drying room and are provided with horizontal water outlet holes, the bottom surface of the drying room is communicated with the air compartment through air outlet holes, and the weighing devices are arranged at the bottom of the drying bin. By the macadimia nut drying device and the macadimia nut drying method, energy consumption is reduced greatly, and drying efficiency is improved.

Description

technical field [0001] The invention belongs to the field of drying device structure, in particular to the technical field of drying granular materials such as nuts and grains. Background technique [0002] When the existing nuts and other particles are drying, pour them into the drying chamber of the drying chamber at one time. Below the drying chamber is a hot air chamber. The hot air blown by the hot air blower is introduced into the hot air chamber, and the hot air passes between the drying chamber and the hot air chamber. The special metal mesh dries the materials in the drying chamber, and the hot air flows upward through the gaps between the granular materials to dry the materials. However, continuous heating at a single temperature for drying and dehydration will cause the outside to dry out, and the interior moisture will not be completely removed, resulting in changes in the cell structure of the nuts. The taste is not crisp, easy to oxidize, not conducive to long-...

AI Technical Summary

Problems solved by technology

However, continuous heating at a single temperature for drying and dehydration will cause the outside to dry out, and the interior moisture will not be completely removed, resulting in changes in the cell structure of the nuts, resulting in a less crisp taste and easy oxidation, which is not conducive to long-term storage, and reduces or even loses the value of the product.
