Problems solved by technology

Natural sun drying method is inefficient and requires early drying and late harvesting, which wastes a lot of manpower. It is greatly affected by natural conditions. The germination rate of seeds decreases due to untimely drying in cloudy and rainy days. Improper operation often reduces the germination rate due to direct ultraviolet rays; mechanical drying The dry method requires a special dryer. Due to the large size of the peanut seed ear, one dryer cannot dry at the same time when the peanut seed volume is large. The high temperature of the machine can easily lead to a decrease in the germination rate of the seeds

Embodiment 1

[0032] A new drying process for peanut seeds is characterized in that it comprises the following steps:

[0033] Step S1, one-time drying: place the peanut seeds indoors, spread them evenly, turn on the fan and dehumidifier at the same time, control the indoor temperature to 30°C, and the humidity to 25%, keep observing the drying conditions of the peanut seeds every day, and wait for the moisture content to drop. To 30% and then into the peanut seeds into the warm air of 35 ℃, continue to dry until the water content is reduced to 25%, that is, to obtain a dried peanut seeds; the thickness of the tiled is 8 cm;

[0034] Step S2, secondary drying: Mix the primary dried peanut seeds prepared in step S1 with the peanut seed desiccant to obtain a mixed material, then place the mixed material in a drying room, turn on the air conditioner, and turn on the exhaust fan at the same time to control the indoor temperature gradient When the humidity is below 20%, turn on the fan to blow t...

Embodiment 2

[0040] A new drying process for peanut seeds is characterized in that it comprises the following steps:

[0041] Step S1, primary drying: place the peanut seeds indoors, spread them evenly, turn on the fan and dehumidifier at the same time, control the indoor temperature to 31°C, and the humidity to 27%, keep observing the drying conditions of the peanut seeds every day, and wait until the water content drops To 31%, pass warm air at 37°C into the peanut seeds, and continue to dry until the water content is reduced to 26%, that is, to obtain once-dried peanut seeds; the thickness of the flat laying is 9 cm;

[0042] Step S2, secondary drying: Mix the primary dried peanut seeds prepared in step S1 with the peanut seed desiccant to obtain a mixed material, then place the mixed material in a drying room, turn on the air conditioner, and turn on the exhaust fan at the same time to control the indoor temperature gradient When the humidity is below 20%, turn on the fan to blow the m...

Embodiment 3

[0047] A new drying process for peanut seeds is characterized in that it comprises the following steps:

[0048] Step S1, primary drying: place the peanut seeds indoors, spread them evenly, turn on the fan and dehumidifier at the same time, control the indoor temperature to 33°C, and the humidity to 29%, keep observing the drying conditions of the peanut seeds every day, and wait until the water content drops To 33% and then feed warm air at 37°C into the peanut seeds, and continue to dry until the water content is reduced to 27%, that is, to obtain once-dried peanut seeds; the thickness of the flat laying is 10 cm;

[0049] Step S2, secondary drying: Mix the primary dried peanut seeds prepared in step S1 with the peanut seed desiccant to obtain a mixed material, then place the mixed material in a drying room, turn on the air conditioner, and turn on the exhaust fan at the same time to control the indoor temperature gradient When the humidity is below 20%, the fan is turned on...

Abstract

The invention discloses a novel process for drying peanut seeds. The novel process is characterized in that the steps are that S1, primary drying is carried out; S2, secondary drying is carried out; S3 and third-time drying is carried out. The invention also discloses a peanut seed desiccant for the novel process for drying the peanut seeds. The peanut seed desiccant is made of the following raw materials including, by weight, 25-35 parts of cinerite, 5-10 parts of sea-foam stone powder, 15-30 parts of bentonite, 6-10 parts of active silicon, 3-6 parts of hydroxypropyl-beta-cyclodextrin, 2-4 parts of super absorbent resin, 3-5 parts of aluminium oxide and 100-150 parts of water. The novel process for drying the peanut seeds is simple, convenient to operate, not high in equipment and reaction condition requirement, capable of quickly and safely drying the peanut seeds, capable of effectively prolonging the service life of the peanut seeds, capable of preventing heating and deteriorationof wet peanut seeds and inhibiting microorganisms growth, beneficial to storage and transportation of the peanut seeds and capable of better promoting germination of the peanut seeds. Higher economic, social and ecological values are achieved.

Description

technical field [0001] The invention relates to the technical field of seed treatment, in particular to a new technique for drying peanut seeds. Background technique [0002] Peanuts, also known as groundnuts, are one of the traditional foods loved by the common people. They have been known as "longevity fruit" since ancient times. Regular consumption of peanuts can effectively prevent the deposition of cholesterol in the body and reduce the risk of various heart diseases caused by cholesterol exceeding the normal value in the human body. The incidence of cerebrovascular diseases, delaying human aging, can also promote children's brain development, enhance the memory function of the brain, activate brain cells of middle-aged and elderly people, promote bone development in children, and prevent bone degeneration in the elderly. [0003] Peanut is also a natural chemopreventive agent for tumor diseases, and it can also reduce platelet aggregation, prevent and treat atheroscler...
