Embodiment 1

[0031] In a typical implementation of the present invention, this embodiment discloses a low-humidity temperature-controlled cycle peanut dryer, which includes a first pair of shell breaking guide rollers 14, a hoist and a drying bin 4, the first pair of shell breaking guide rollers The bottom of 14 communicates with the hoist, and the discharge port 3 of the hoist is positioned at the top of the 4 feed ports of the drying bin body; There is no clear physical boundary between the section and the section; the drying bin body 4 in the present embodiment is cylindrical, and its interior is hollow, and the upper end is provided with a material inlet, and the bottom end is provided with a discharge port 3, and the output of the drying bin body 4 Port 3 is also communicated with the feed inlet of the first cracking guide roller pair 14 to circulate and dry peanuts.

[0032] The ultimate goal of drying peanuts is to obtain dry peanut kernels, which are isolated from external heating ...

Embodiment 2

[0053] In a typical implementation of the present invention, this embodiment discloses a low-humidity temperature-controlled cycle peanut drying method, using a low-humidity temperature-controlled cycle peanut dryer as described in Example 1, and the steps are as follows:

[0054] Peanuts enter the hopper 1, pass through the first pair of guide rollers 13 that rotate in opposite directions, and then pass through the first pair of shell-breaking guide rollers 14, and the shells are broken under the action of the needle-like protrusions. Peanuts that have not fallen on the protrusion are peeled off, and the peanuts are pierced by the needles on the needle breaking roller to break the shell, and enter the bucket elevator 2 through the feeding plate 18; the peanuts are sent into the drying tower through the belt 20 with the hopper 24, and From top to bottom, the peanuts pass through the drying bin 4 and enter the lower hopper 23, then the peanuts pass through the second pair of gui...

Abstract

The invention discloses a low-humidity temperature-control circulating peanut drying machine, and belongs to the technical field of agricultural machinery. The machine is characterized in that pod shells are subjected to needle breaking treatment in the earlier stage of peanut drying by virtue of a needle breaking structure, so that internal moisture can be dissipated outwards in the later drying process; optimal dry air is provided for the whole machine by means of a low-humidity temperature control heat source technology, and meanwhile, the drying energy consumption is reduced and the energy cost is reduced by utilizing circulating waste heat; the machine comprises a first shell breaking guide roller pair, a second shell breaking guide roller pair, an elevator and a drying bin body, the bottom of the first shell breaking guide roller pair communicates with the elevator, and a discharging opening of the elevator is located above a feeding opening of the drying bin body; the drying bin body is divided into a plurality of sections which are communicated; the second shell breaking guide roller pair is arranged at the bottom of the drying bin body, and the bottom of the second shell breaking guide roller pair communicates with the elevator so as to circularly dry peanuts; and needle-shaped protrusions are arranged on the surfaces of guide rollers of the first shell breaking guide roller pair and the second shell breaking guide roller pair so that the peanut shells can be punctured. The drying bin body further communicates with a hot air source capable of outputting high-temperature low-humidity air.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a low-humidity temperature-controlled cycle peanut dryer and a drying method. Background technique [0002] Peanuts are one of the most important oil crops in my country. After harvesting, peanuts have a high moisture content. If they are not dried in time, they will become moldy and deteriorate, which will affect food safety. At present, most peanuts are still dried by stacking in the field, which is greatly affected by the weather, with low drying efficiency and poor quality. Since peanuts are dried in the form of pods after harvest, the different structural composition and moisture content of peanut shells, red coats, and peanut kernels affect the drying efficiency of peanut drying equipment. Most of the existing drying equipment adopts low-temperature hot air drying method. Since the pod structure cannot be changed, the drying time is long, the eff...
